The classification of industrial electronic belt scales

The classification of industrial electronic belt scales

According to the mechanical structure type of industrial electronic belt scale

1. According to whether the belt conveyor mechanism has been made into an integrated structure when manufacturing the belt scale, it can be divided into:

Embedded type belt scale and whole type belt scale. The embedded belt scale and its supporting belt conveyor may not be designed and manufactured at the same time. Usually, the belt scale manufacturer will go to the user's site and install the weighing unit (including weighing platform and weighing sensor) on the rack of the belt conveyor which is usually separately provided by the user to form the weighing system together. The conveyor required by the whole type belt scale, including conveyor frame, roller and roller, conveyor belt, drive motor and so on, has been designed and manufactured into an integrated structure with the belt scale weighing components, the length of the conveyor is generally shorter than the embedded type.

2. According to the bearing device type of belt scale, it can be divided into:

Weighing table belt scale and conveyor belt scale. The bearing device of the weighing table belt scale only includes part of the conveyor. As a part of the belt conveyor, this kind of belt scale transports materials together with the belt conveyor. The carrying capacity of conveyor belt scale is a complete conveyor. This kind of belt scale has its own power and can transport materials independently.

Divided into: single - speed belt scale, multi - speed belt scale and variable - speed belt scale. Among them, the multi-speed belt scale can be scheduled in several different speed belt speed, while the variable speed belt scale can be within a certain speed range without change. If the above belt scale in use only one of the fixed design belt speed, also known as the constant speed scale; If in use will need to change the material flow and in its design with speed within the range of regulation, also known as speed control balance.

3. According to the feeding side of the belt scale, it is divided into:

Feeding belt scale and dragging belt scale. In the former case, the materials in the silo are not in direct contact with the conveyor belt, but are fed to the conveyor belt successively by other feeding devices (such as vibrating feeder, disk feeder, star feeder, etc.). In the latter case, materials in the silo are pressed directly on the conveyor belt and dragged out when the conveyor belt is in operation. For the towing balance, the variable speed balance should be used to change the running speed of the conveyor belt to adjust the material flow. For the feeding scale, it is generally used to adjust the feeding speed of the feeding device to change the flow rate of the material. The belt scale with suitable speed can be used for many purposes, or it can be used occasionally. If necessary, the feeding speed of the feeding device and the running speed of the conveyor can also be adjusted simultaneously.

Digital electronic truck scale in the rainy day how to do bubble water?

The daily use of digital electronic truck scale is more afraid of lightning strike and bubble water, but in case of digital electronic truck scale bubble water how to do?

First, check the junction box. If the junction box is flooded, all the signals of the weighing sensor are sent out by the junction box. And the circuit inside the junction box is short-circuit due to water, then the signals sent out must be unstable. The treatment methods used are:

Remove the junction box, dry the water in the junction box with a hair dryer, and try again to see if it weighs properly. If it still doesn't work, the junction box needs to be replaced.

2. The four corners of the weighing sensor of digital electronic truck scale will be too large when it is flooded. If the electronic weighing sensor is net soaked in water for a long time, the internal circuit of the weighing sensor may be damaged, resulting in too many weighing errors; The solution is:

Measure the weighing sensor on one side with a multimeter to see which weighing sensor has been damaged. Generally speaking, the cost of repairing the weighing sensor is relatively high, and the repair time is also relatively long, so it is more appropriate to consider direct replacement.

3. The external environment for the electronic scale load sensor formation is mainly the following aspects, the influence of the high corrosive environment, such as moisture, acid formation of sensor elastomer, damaged or short circuit, so if the digital electronic truck scale, environment is poor, should choose the shell made plastic or stainless steel shell junction box, good corrosion resistance and impermeability.

The four-step method of selecting electronic scale scientifically

The four-step method of selecting electronic scale scientifically

Many people have the experience of weighing themselves on the scales and weighing their mobile phones on the scales, but the consequences of weighing can be very inaccurate. Because the difference of industrial environment makes the application environment of scale complex and changeable, each kind of scale has its special purpose. If in the industrial production of mixed use, wrong use, it will affect the quality of products. Only by using the proper scale, can we obtain the reliable weight result and guarantee the product quality. The "Four Steps of Choosing a scientific scale" can help friends to better choose their own scales.

 

Step 1: Determine the weighing environment

Weighing environment refers to the external environment in which on-site temperature, humidity, dust and vibration will have a significant impact on weighing consequences. According to the different external environment, it is necessary to choose different scales to meet the needs of the site. Such as: it is very humid environment, it is necessary to choose IP grade high scale.

Step 2: Determine the requirements for weighing accuracy

This step is an important step in the scientific selection of scales, and it is necessary to confirm two aspects of information:

(I) Process requirements

It can be understood from the following three questions:

What is the maximum weight that can be weighed? (including tare)

What is the minimum weight to weigh? (Excluding tare)

What is the weighing tolerance? The weight determines the scale; The minimum weight and allowance for weighing determine the accuracy requirements of the scale.

(2) The accuracy of the scales

There must be an error between the weighing result and the actual value of the scale. The error is caused by linearity, Angle difference, repeatability, lag, temperature stability, stability time and degree. Because of the different design concept and sensor instrument technology, the error will be very different.

Step 3: Define the requirements

In accordance with the trade settlement demarcation, if the scale used for commercial transactions is priced by weight, it must be defined as "trade settlement". The scale must meet the requirements of China's national measurement laws and regulations.

Confirm explosion protection requirements

Scales used in explosive environment must comply with China's explosion-proof regulations. Application building must meet the requirements of explosion-proof area.

Step 4: Determine what is necessary

With the development of the function of the scale, jinan electronic scale is not simply to provide you with the weighing results, choose different effects of the scale can greatly affect the production line.

Tips for hook scale - tak kong hook scale

Although the aluminum alloy material is very good, if the technology is not good, it will affect the aluminum alloy effect. So, when you buy hook scale, not only to see the hook scale shell material, but also need to pay attention to the production process of the hook scale. Because aluminum alloy is a die-casting molding, if not a die-casting molding, then there will be a big gap, from this point, will certainly have a great impact on the hook scale. Therefore, we must carefully check this point, for each gap is necessary to observe, or there is any leak, the hook scale interference is very big. So, must want to hold good every detail, use rise so simple and convenient a lot of. In addition, also need to pay attention to the aluminum alloy shell do not use some corrosive liquid to wipe, just use water to wipe.

Key words: hook scale

Hook scale market details - tak kong hook scale

Hook scale is used in the external environment of the equipment, this equipment often need wind blowing rain, so for the shell manufacturing process and material requirements are very strict, if not up to the requirements of the hook scale, then such a shell will be eliminated, and is easy to cause a variety of rust phenomenon. Then what kind of material is better for the shell of hook scale?

 

At present, the market sales hook scale, the use of the shell of aluminum alloy, channel steel, stainless steel three kinds, the three types of material, actually have its good place, the advantage is very obvious. But because the hook scale shell is used in the external environment, many factors can not be ruled out, so the three materials are required to resist the impact of some external strength, not only electrical and thermal conductivity is good, but also need to do not easily deformation. From these requirements can be analyzed, the effect of aluminum alloy is the best, because although channel steel quality is also very good, conductivity and thermal conductivity is good, but do not because the channel is generally very hard material, used as a beam, so the conductive it is must be strictly forbidden, so, channel steel hook scale is commonly used in indoor, but cannot be used in outdoor. In addition is stainless steel, stainless steel stability is obvious to all, but stainless steel relative to aluminum alloy, to be thinner, that is to say, use stainless steel to make hook scale shell, easy to appear phenomenon is deformation, so it is very inappropriate to use in the field of hook scale. Such calculation down words, only the most suitable use of aluminum alloy in the hook balance of the shell. Because, in the aluminum alloy, increased the alloy element, and the existence of the alloy element, can ensure that in the use of the phenomenon, will not appear deformation, more stable. And the strength is higher, because it adds high strength aluminum, and aluminum stability and strength is relatively high, so that, even in the face of a strong impact, it is difficult to make this hook scale shell change. In addition, aluminum alloy has a great advantage is the density, the density is not easy to be eroded by external forces. At this point, the advantage of aluminum alloy is very obvious, so aluminum alloy will be used in the hook scale field, and is used in the most important shell above, to protect the hook scale.

Electronic loadometer debugging method
Electronic loadometer debugging method
1, electronic loadometer bearing key debugging, the weight equivalent to the maximum weight is evenly added to the electronic loadometer bearing platform, according to the various weighing display instructions in the position and method, so that the display value and weight value is consistent, remove the weight, and confirm that the empty balance is displayed as "0". Finally, the maximum weight is divided into several parts, which must include the minimum weight of the scale, the maximum weight and tolerance change of each weighing point, requires that the weight error of each point of the electronic weighometer is not greater than the maximum tolerance requirements of each measuring point.
2. Use the digital voltmeter to measure the output voltage of each weighing sensor of the electronic weighometer in turn. If there is any inconsistency, the corresponding two precision adjustable resistors in the junction box can be adjusted to reduce the difference between them. However, the adjustment must be noted that the rotation direction of the two adjustable resistors should be the same, and the rotation amount should also be the same. When rotating clockwise, the resistance will decrease, the output voltage will increase, and the display value will increase; otherwise, the other way around. Until adjusted to the electronic loadometer only weighing sensor output consistent. Debugging generally available weight method, the biggest weighing weight, 1/10 in turn put to electronic scale load bearing center position and the weighing sensor at the top of the bearing platform, only with real difference method to measure accurately the only differences of the weighing sensor output quantity, at the same time adjust each ChengChongDian electronic loadometer weighing sensor respectively corresponding two precision adjustable resistance, decrease the difference between each other, but the direction of rotation and rotation as well....
Common problems in the use of electronic loadometer
Common problems in the use of electronic loadometer
1) the value is out of tolerance
Indicates that the indication error of electronic loadometer is greater than the maximum allowable error of national verification regulations. The simple error of indication is not a fault. Because any kind of measuring instrument after working for a period of time, certain performance have a certain amount of change. Electronic loadometer after installation and debugging, the various performance measurement are within the scope of permissible error, the error will change after using for a long time, there may be error is greater than the value for use in the margin of error, namely "error", it is difficult to find, for the operator only calibration measurement department personnel verification can be found in the standard weight.
2) faults caused by environmental problems
One of the main reasons is the use of electronic loadometer site environmental hygiene is poor, such as long-term weighing bulk, debris, dust into the scale under the square or crawler into the internal meter, when the damp weather, debris and dust due to moisture absorption and conductivity, causing components or circuit fault, sometimes may burn components. This type of failure is usually abnormal display.
3) sensor failure
The electronic loadometer is generally used in parallel with 4~10 sensors, and its error is generally less than 0.02%FS. The damage of the sensor is mostly caused by weighing overload, improper use or internal quality (patch, insulation, etc.) of the sensor. Therefore, the protection of sensors should be strengthened....
Why digital truck scales?

Why digital truck scales? Hebei truck scale manufacturers for you to introduce it:

For electronic truck scale with digital sensor, the adjustment of the Angle difference of the scale body only needs to be made on the instrument or computer to adjust the coefficient of the corresponding sensor (or it can be done automatically by the instrument or computer). Due to the superposition of digital signals, the output signal is large and the signal-to-noise ratio is much better than the analog sensor, which improves the accuracy of measurement data.

Digital electronic truck scale has the function of fault self-diagnosis, which is convenient for fault treatment and maintenance. In the scale body using analog sensor, to replace a sensor, the whole scale body needs to be adjusted and calibrated again, and the digital sensor has good consistency, no need to adjust the original measurement after replacing the damaged digital sensor, only the number of the sensor in the field can be trimmed. Because of the digital signal output by each sensor, it has strong anti-interference ability and avoids the metering error caused by the continuous connection error of the analog sensor and the temperature change of the impedance of the long-distance transmission line.

Due to the digital sensor response speed and communication speed is not very high, only suitable for the use of static electronic truck scale. Finally, through the digital transformation of the electronic truck scale, the main convenient debugging and maintenance work, to ensure the accuracy of measurement data and operation stability n, but due to A/D conversion within the digital sensor.

CPU and communication interface increase the cost and make the distribution cost too high. There is A digital junction box with analog sensor, which is suitable for multi-sensor metering system. The analog signal output by the sensor is converted into digital signal through A/D, making the analog sensor have the function of digital sensor. Because a truck scale only needs a digital junction box, so the cost is not very high, in the multi-sensor electronic scale, has a wide range of promotion value.

Through a common type of electronic crane scale after in-depth research, said from the electronic crane to crane scale, appeared on the electronic application direction in all kinds of new balance always has its very wonderful part, from the principle of crane scale design direction to give analysis found that actually crane scale on the specific principle of master has its natural aspect, from the whole application architecture of electronic crane said to understand the future of balance control exactly what are the defining standard, we also is not hard to find, we use the original hook scale and the process of electronic crane scale, gradually feel the charm of intelligent. From the previous application of various types of electronic scales to give the reference discovery, high quality electronic weighing is often inseparable from some places worth playing.
In fact, whether it is electronic scale or other types of weighing tools, we can always find that in the actual standard of control of the hook scale, everyone can more or less find that almost all the analysis mechanisms for the control of the crane scale have their clear definition of use.
Hook scale has a lot of development space waiting for people to dig, xingtai degang electronics co., LTD has been with you!...
Hook balance overload of the disadvantage
Hook balance overload of the disadvantage
You know the hook scale can move a lot of volume for us, but it is also limited. If it exceeds its rated power, it will become an overloading state. What's the harm? Xingtai dehong electronics co., LTD. Is organized as follows:
Increase operational risk
Originally for the use of hook scales, there is a certain risk factor. However, if the operation can be carried out strictly according to regulations, it can guarantee the safety in the operation process. However, in the case of overload weighing, it may lead to an increase in the risk factor, which may lead to a dangerous accident in the operation process. In general, overuse will cause damage to its hooks, which will lead to the accidental fall of the weighed goods. After all, for such a weighing tool, the items that are weighed tend to be heavier. Therefore, it is necessary to avoid overloading, so as to avoid the increase of risk factor.
Internal parts were damaged
Overload weighing not only increases the risk of accidents, but also causes damage to the tools' internal parts. In the process of overloading and weighing, the pressure of its parts increases beyond its capacity, resulting in damage. In such cases, it is necessary to replace the parts, resulting in unnecessary expenditure. Weigh in strict accordance with the regulations, do not exceed the maximum value of the weighing, it can certainly reduce the damage to parts, so that the use life of weighing tools can achieve the longest effect.
Affects the performance of weighing tools
If the hook scale is overused for a long time, it will affect the performance of the tool. From a professional perspective, such tools are relatively stable in weighing performance and can ensure the accuracy of weighing. However, if overloading is used, its performance will be affected, resulting in failure of performance, failure of accurate weight data display, and greatly reduced overall performance. For weighing tools, once there is imprecision, it will lose its original value and meaning.
Therefore, when using the machine must take care of the bearing capacity, do not let her bear too much, otherwise things will be turned against you!...

Attention should be paid to the use of electronic hook scale.

The electronic hook scale is a precision measuring instrument. Special attention should be paid to the following points in application.
1. The electronic hook scale has good anti-vibration and rain-proof performance, but it should avoid violent vibration and long-term rain, especially when it falls from the hook.
2. When working in high temperature environment, electronic hook scale should pay attention not to let the scale stay in high temperature area for a long time. The general principle is that scaling shell hot (70 C) will not have adverse effects on the scale.
3, avoid overloading to avoid damage to sensors.
4. When stored, it should be placed in the matching packing box. The storage area should be ventilated, and the relative humidity is not greater than 85%.

As a necessary dynamic weighing equipment, the precision of electronic belt weigher is unavoidable in the day after day, which determines the profit of the enterprise and the heart of the enterprise manager.
Although the belt conveyer is equipped with a constant belt tension automatic regulation device, it can only adjust the tension change caused by heat expansion and contraction, especially in summer. The "hot" phenomenon produced by the high temperature on the belt scale is particularly obvious. This requires the operator to master the daily maintenance knowledge of the belt scale, and learn how to maintain and maintain the electronic belt scale in summer.
After a period of time, the precision of the belt weigher must be checked, including zero point calibration (belt scale zero) and chain code check (or physical check, hanging code check), and its accuracy has been detected.
To check whether the electronic belt scale can operate smoothly without vibration, whether the mechanical parts are flexible or not loose.
If installed in the indoor electronic belt scale, the ventilation and drying should be maintained during the summer high temperature and rainy season, so as to prevent the belt from overheating and sticky and affect the weighing accuracy.
If the electronic belt scale is installed outside, it must be symmetrical on the various sensors and electronic equipment on the heavy frame to protect against rain, lightning and high temperature exposure.
Check whether the running of the belt has the phenomenon of deviation.
Regular electronic belt scale cleaning, eliminating unnecessary interference factors affecting the accuracy of measurement.
There are more thunderstorms in summer. It is necessary to ensure good grounding of the scale (including metal conductor parts such as signal lines and junction boxes), otherwise the belt scale will be damaged due to lightning.
Do not weigh work in thunderstorm weather, and cut off all the power supply of the belt scale to prevent static electricity generated by lightning.
In the summer, safety production must be carried out and prevented from happening.

1. form of foundation pit:
There are two types of foundation pit for electronic truck scale, one is no foundation pit, the other is shallow foundation pit. The shallow foundation pit is the installation method of the automobile scale in the foundation pit, the surface of the scale platform and the ground, and the car balance without foundation pit is installed on the ground. It can be regularly cleaned, no water is accumulated, and the cost is cheaper. Generally choose the installation method of all electronic truck scale without foundation pit.
2. site selection:
The installation position of truck scale should have a good drainage channel, and will not be flooded with truck scale due to rainstorm or flash flood. For shallow foundation pit, drainage channel should be set up. In addition, the two ends of the truck scale must have a straight length of enough length for the upper and lower scales of the vehicle. The two ends must be at least equal to the length of the scale.
Another factor that affects the installation position of weighing apparatus is the number of cars you weigh every day. If you weigh only about twenty cars per day, a car balance should be enough to make a double - phase road. If you have to check in about 50 cars every day, you need to get ready to stop, a car balance should be enough, and it's best to prepare a by-pass. If you go far more than 100 cars a day, you should consider two car scales at the same time. In use, each weighing instrument can weigh heavy cars or empty cars in two directions and use by-pass.
You should consider: where should the car stop? Do you want to queue up at the time of the pound? What happens to heavy snow, heavy rain or during peak season? And so on, you need to pay attention to it.
3. basis:
The truck scale must be built of concrete foundation. This foundation must be excavated below the local permafrost line. In the construction, the concrete marks should be guaranteed. The embedded parts should be poured to ensure the geometric dimensions of the level, the position degree and so on. In the irrigation of concrete, it is necessary to ensure the non displacement of the embedded parts. After completion of the foundation pouring, it shall be maintained according to the civil code, and the truck can be installed only when the concrete reaches the design strength index. If we want to shorten the curing period, we should take measures such as adding "early strength agent" under the guidance of professional technicians. To prevent thunder, you should set up a grounding pile according to the local conditions and ensure the grounding resistance <4 Europe. From the center position of the scale to the pound room, a pipe should be laid to wear the signal cable.
Please refer to our company's basic plan, basic construction period and basic maintenance period. It will take about 20 days before and after construction.
4. lbs. room:
The pound room should be close to the car scale, in order to place weighing instruments, or computers, printers and other equipment. In addition, to ensure that the officer can also contact the driver, transfer the balance sheet, ensure the car scale, identify the license plate number and check the goods and so on.
5. installation and verification:
In most cases, the units are responsible for installation and commissioning, and the manufacturers assist in installation.
Crane (or forklift truck), Jack (greater than or equal to 5T) 2, level, electric welding machine (need time) and two odd jobs.
After installation and commissioning, the certificate can be officially opened after the certificate is verified and issued.

Below, I will give you a brief introduction to how to resist the interference of the Shanghai electronic scale. The most effective method is the product grounding method, and the following small editor says the benefits of grounding.
Benefit one: the electronic scale product is better to increase the distance between the grounding device in the process of installation.
The two benefits: the greater the depth difference between the earthing bodies in the installation of electronic scales, the less interference between them, but in practical use, increasing the depth of the grounding body can reduce the grounding resistance, but it will damage the economic benefits, so we can increase the length properly.
Benefit three: the grounding of the electronic scale product installation process can prevent the lightning strike in the rainy weather, so the grounding wire should be introduced to prevent the interference from other grounding systems, especially the lightning protection or the neutral point grounding wire system of the power network.
And the electronic scale products should be grounded in the process of installation....

There are many types of hook scale products, in the form of work: axle seat type, driving type, hook head suspension type, embedded four kinds, generally applicable to transportation, steel market, building materials market, papermaking, industrial and mining and warehousing and other industries on the loading and unloading of goods measurement.

Hook scale products can help many industries in the air and unstable space for loading and unloading and accurate measurement, reducing the working time, at the same time can at the same time loading and unloading, measurement work. Speed up the work efficiency of enterprises, reduce a lot of manpower and material resources, and are suitable for a large number of loading and unloading industry. When used, the operation is convenient, flexible, and does not occupy space. The remote metering can be monitored and controlled in high altitude. The product can not be controlled without a long distance, and the maximum equipment and energy saving state is achieved. Many times we see high altitude cargo handling, also encountered some people were injured in the work. So the hook scale is very careful at this point. It sets up remote control and has no remote control settings relative to the electronic weighbridge. In this way, there will be no accidental injury in the work, and also ensure the safety of the work.

The hook scale uses the advantage of the horn hook.

1. the hook hook is directly connected to the sensor, which has simpler structure and lower production cost. Although the structure of the eye hook is relatively simple, the shaft pin connection is adopted, which virtually increases the cost.

There is usually a connecting device between the 2. eye hook and sensor, which is threaded through the sensor. Practice shows that thread connection is usually the weakest link in the whole hanging system. But the use of horns hook does not have to worry about this problem.

In the purchase of electronic hook scales, there will be such a problem, such as the hook scale free warranty for 1 years, but the battery inside only 3 months warranty, some purchase may have a very good opinion. In fact, the sales manufacturers have his reason, the same hook scale battery, some companies can use two years, three years or even more, some companies may not be bad for a year, in fact, this is also related to the user's own method of use. How can we make our hook cell longer?
1, the first very important is the battery charging time, can only be filled with the original charger, it is possible that there are several hook scales in the company, and sometimes the charger is not up to the number, this later will be very problematic, very bad battery.
2, if the temperature is very low, as little as possible with the hook scale, I said here is less use, not do not use, because the temperature is low long time work on the facade nickel cadmium battery damage, more tragedies are often see some factories directly put the hook scale in the open area, that is a few degrees below zero degrees ah.
3, if not, the best artificial discharge.
4, this is the same as general cell phone batteries, electric vehicle batteries, is the first time when charging, it is best to rush for 12 hours or more.
5, the new battery starts with several charging and discharging processes to achieve the best results.
6, even if it is not the first charge, if the charger is full, it is best to rush for a few more hours. This is only good for the battery, and it's no harm.
7, if there is no need for an electronic hook scale for a period of time, it is better to put off the hook scale and put it in a dry and cool place.
Through the above knowledge, I believe that in the future use of electronic hook scales, how to let your hook scale battery life longer have a deeper understanding.

When the electronic hanging scale is working in the open air, it will cause great damage to the electronic crane scale when it meets thunderstorm and is struck by lightning. Lightning is a common natural phenomenon, and some electronic scales must work in the open-air environment. Facing this situation, how to prevent lightning strikes is particularly important. According to the requirements of modern lightning protection technology, the concept of comprehensive protection, system protection and level by step protection is set up.
The lightning protection that the electronic hanging scale needs to do:

1. special equipotential lightning protection for all parts of the electronic weighing apparatus such as electronic scale sensor and two meter.
2. cut off the electrical channel of the sensor elastomer and scale platform, and provide the discharge channel of the current.
3. power supply system for multilevel lightning protection
4. build a lightning protection grounding network around the electronic scale, including the scale foundation. The whole system is single grounded near the scale.
5. installation of lightning recorder, real-time detection of electronic weighing instrument lightning protection system, the main interference and suppression technology of electronic scale.
1. Power interference
2, alternating current interference
3. Induced interference
4. Radio frequency interference
5, electrostatic interference

The electronic scale generally realizes the above technology. In the thunderstorm day operation, the possibility of being struck by lightning or being disturbed is greatly reduced, which ensures a great majority of safety and does not affect the work process.

Electronic belt weigher - basic composition
(1) belt conveyor and its driving unit (although the manufacturers of embedded belt scales are generally not provided, but if the belt scale is not complete, it can not work properly.) Weighing unit, speed measuring unit, signal acquisition, processing and control unit.
For conveyor belt scales, the whole belt conveyer is the loader; for the weighing platform belt scale, its weighing and weighing roller and the conveyer belt that run just above it constitute the loader.
The weighing sensor is a component that converts the gravity of the said material into analog or digital electrical signals. The combination of weighing table and weighing sensor is often called weighing unit. The electronic belt weigher, as a dynamic measuring instrument, is also used to measure the speed of the said material.
Signal acquisition, processing, and control units are electronic devices used to receive and process electrical signals from the output of sensors, to give measurement results in units of quality, and to complete other predetermined functions. It can be a single instrument (such as a "dynamic weighing display controller"), or a combination of several independent parts (for example, a separate sensor to stimulate a power supply, a signal collector on the site, an integrator for a central control room and a upper computer, etc.). In order to describe the convenience, this volume tutorial often referred to signal acquisition, processing, and control unit (both single and combined) as "display control device"....

In addition to the quality of the electronic belt scale, the actual precision of the electronic belt scale depends to a great extent on the situation of the belt conveyer to install the electronic belt scale, the selection of the installation position of the belt scale, the quality of the installation and the maintenance of the site operators. In the actual installation, we often touch on the following aspects, and make a brief introduction to the problems and solutions at the scene.

One, the situation of belt conveyer

At present, most of the production plants of belt machines are TD75 or DTII belt conveyer. Because the production plant is not strictly according to the standard in the process of production and installation, it has a great influence on the installation of the follow-up electronic belt scale.

1. When the belt conveyer is transported by air, most of the middle flat roller of the groove roller does not rotate or turn. This is mainly because the height of the driving drum and the reformed drum is slightly higher than the nominal height of the groove roller. When the material is on the belt, the belt is attached to the middle supporting roller by gravity. This kind of belt machine has little influence when it is used only for transportation, but the belt conveyor must be reformed when the belt weigher is installed. The simple practice is to make the support roller support as a whole. If the belt is too narrow or too tight, it must be high in the middle of the middle flat roller of the groove roller, so as to ensure that the belt conveyer is transported by air. Each roller can rotate normally. Otherwise, in the process of measuring the belt scale, the horizontal tension of the belt counteracts the downward gravity of some material, so the belt scale sensor can not accurately weigh the material weight on the belt, and the influence on the measurement precision is very large, and the measurement precision can not be guaranteed. The concrete method of high roller cushion is to weld a certain height on both ends of the shaft of the middle pinch roller. The concrete height of the pad can be held by the middle roller, and the quantity of the transformation is not less than 6 sets of rollers at both ends of the belt scale.

2. The precision of the manufacturing precision of the roller frame of the belt conveyor is low. Because the production quality of belt conveyor trough type roller group is uneven, it is necessary to check the dimension of the roller. In the process of site installation, we found that the height of the two pillars of the support roller support is not consistent, which causes the middle roller not to be horizontal, one is that the belt is easy to run off, and the two is to influence the measuring precision of the belt scale. The solution is to install the thin wire rope or fine wire on both sides of the belt conveyor of the belt conveyor when the belt conveyor is installed. The support of the middle roll to the belt and the rotation of the rotor should be observed after the two sides of the roller are normal. If the problem is found, the roller frame should be removed to measure, and the change or replacement should be carried out if it is incorrect.

3. The height of the middle frame of the belt conveyer is not consistent. The main reason is that the quality of the belt conveyer is not qualified, or the height of the left and right side changes due to the long-term use. If the level height difference is too large in the installation, it is impossible to guarantee the normal installation of the belt scale frame, so the belt conveyor should be adjusted. According to the height of the difference between the left and right, the level of the roll group is not less than 6 groups before and after the belt scale, and the scale body level is guaranteed in the installation, so that the measurement accuracy can be guaranteed.

Two, the installation location of belt scale and attention to the general situation, the user order the belt scale in advance to consult, to the belt scale production plant, such as conveyor belt width and length, maximum transmission, measurement precision requirements and other data, by the belt scale manufacturers to assist selection, model initial determination, and then the user to provide The size parameters of the belt conveyor or the manufacturer send people to the site for actual measurement. If the user only provides the type of belt conveyor, the belt weigher production plant must pay attention to the actual measurement of the size of the belt conveyor and the middle frame, so as to avoid the difficulty in installation of the belt scale size and the actual size of the field, which may seriously affect the measurement accuracy. If the construction and installation of the belt conveyor is still not carried out, it is only purchased according to the design drawings, then it is necessary and the user to ask which manufacturer produces the belt machine, and then the belt machine manufacturers further determine the type and size of the belt conveyor, if possible, the belt machine can be installed to carry out the field measurement, or Ask the user to request the belt machine factory to make and install strictly according to the standard, avoid the size of the belt scale scale and the actual size of the belt conveyor, and affect the measurement accuracy. After installing the personnel to the installation site, we must first determine whether the size of the belt scale is in line with the size of the site, and it can be installed without error. In addition to strictly operating according to the installation requirements of the belt scale, we should pay special attention to the following points:

1, select the installation location. The selection of the correct installation position of the belt weigher is very critical. Some users may specify the location of the installation. The site installation personnel must choose according to the actual situation of the belt conveyer, and find that the designated position of the other side has a reasonable place to explain to the other party, and it can not be moved to each other blindly. When the driving drum of the belt conveyor is on the head, the scale should be positioned in the middle and near the tail cutting point. The support at the installation position of the belt scale should be strong enough to be properly reinforced when the strength is insufficient.

2. The belt conveyor with convex arc segments should be at least 6m above the convex arc curve. The belt conveyor with concave arc segments should be at least 12m above the concave arc curve.

3, the aligning roller, the guide roller or the vertical roller must be at least 183 meters from the belt scale before and after the belt weigher. It can not be satisfied at least 6 meters away.

4. The 4 groups of transition rollers before and after belt weigher should be slightly higher than other belt conveyor idlers 1 - 2.

We all know that the electronic hook scale is a very practical electronic weighing device. In fact, no matter what he is good or not, he is good for us as long as we are fit for him. But many users are lack of experience in choosing electronic hook scales. They don't know our electronic hook scale too much. So it is very hard to choose and buy a better electronic hook scale.
Selection of electronic hook scales of small skills:
1) in the case of steelyard, such as steelyard, if it is in the room, it is possible to choose a direct view electronic hook scale which is convenient and convenient to read in the near distance, and the wireless digital electronic hook scale is suitable for the outdoor selection of remote control operation.
2) light and shade can be chosen in bright occasions because of light and dark in weighing occasions. LED screens with higher brightness are selected on darker occasions.
3) the environmental factors are influenced by the temperature, humidity and explosion of the working environment, so the electronic hook scale should be selected according to the environmental factors. If it is a high temperature occasion, it is necessary to choose the high temperature electronic hook scale.
4) the wireless hook scale should be chosen at the distance from far and near to the needs of long distance or high altitude in metallurgical and wharf occasions.
5) the weighing range electronic hook scale has a certain range and the bearing limit, so we should also determine the appropriate range of the electronic hook scale according to the range of the weighing required.
6) the frequency of the use of the scale in some occasions when the frequency is frequently used, it is necessary to choose the long and durable electronic hook scale, otherwise the frequent charging will affect the normal work of the occasion.

The electronic hook scale is not working. How to find fault? The repairman must have a certain knowledge of electronic technology and digital circuit to repair the electronic hook scale. Before the hands-on repair, we must first understand the failure and use of the trouble to the user. For example, understand the use of the electronic scale, environmental conditions, the phenomenon of overweight, scale body, instruments have no collision phenomenon, first according to the normal use method, make the scale in the live working state (scale body can not hang on the crane).

1, check whether there is abnormal sound, whether there is alarm, whether there is a regular sound interval.

2, whether the scales or meters have abnormal smell, such as transformers, plastic wires, printing boards, etc., may cause a lot of abnormal smell due to the heating and burning of the circuit.

3, look at the display status of the display, whether the appearance is damaged, whether the components are broken or welded. 4, touch integrated chip and electronic components, feel its temperature is too high, the suspicious components can be replaced directly with a good device, this method is very effective for the whole machine's large current failure phenomenon. 5, the operating electronic hook scale function is normal, the key is flexible, can combine "listen" and "look" at the same time, can quickly reduce the scope of finding the fault, to lay the foundation for the next step.

1. The composition of the belt scale consists of four parts: weighing frame, weighing sensor, speed sensor and display instrument.
Two, the control principle of the belt scale
1. The scale is used for the quantitative feeding of scattered materials. In the process of feeding, the feeder is continuously supplied by the belt. The feeder will transport the material from the user to the silo or other feeding equipment in the future and carry on the weight test through the weighing bridge. At the same time, the speed sensor of the tail wheel is installed to carry out the speed measurement of the belt. The measured weight signal and the speed signal are sent to the MT3105P integrator to perform differential processing and show the instantaneous flow per hour per unit. According to the corresponding signal value (PID signal) of the output of the deviation size, the speed of the motor is changed by the frequency converter to change the feed amount, so as to make it with the set value. In order to complete the control of the constant feed flow. From the weighing principle, the instantaneous flow rate of the material measured by the electronic belt weigher depends on two parameters, that is, the instantaneous flow rate is equal to the material load value Q (kg/m) measured by the weighing sensor and the two parameters of the velocity value V (m/s) measured by the speed sensor. That is, w (T) =qv can be seen and the speed sensor is measured. The accuracy and stability of measurement are equally important to the accuracy and stability of weighing sensors. At present, the accuracy of weighing sensors is generally increased to a few thousandths, and the accuracy of the speed sensor is mostly in a few thousandths, so improving the accuracy of the speed sensor is one of the ways to improve the accuracy of the electronic belt scale system.
2, starting feeder: press the start button in the field operation box 1SB, 1KA1, 1KA3 relay at the same time, the frequency converter starts the signal closed, at this time the feeder and the motor fan start running, the running indicator 1HL2 light (when the proportioning scale fails this light flashes), through the spot speed knob 1RP to make the frequency converter output current change and The motor speed is also changing. During the running process, it is found that the stop button should be pressed by 1SB2, the belt should be adjusted, or the machine can be switched on. The central control boot usually talks about the switch switch to the central control position. The panel's ready lamp must be on the bright side, otherwise it will not be able to turn on the middle control or damage the lamp.
Three, setting of parameters and calibration of weighing feeder
1, calibration of instrument parameters: after the belt tends to be stable for a period of time, the parameters of MT3105 instrument parameters can be set, such as the position of the small number point of the input instrument, the unit and capacity of the scale, the capacity of the sensor and the sensitivity of the sensor, and the length of the belt for one week. Initial use requires input of original parameters, and normal use usually does not need to be altered at will.
2. The calibration of weighing feeder: first obtain the test cycle, then carry on the zero point calibration, the zero point can be calibrated after the stable, the interval calibration can be divided into physical calibration, chain code calibration, hanging code calibration and other methods, using the special AUTO MAT (automatic material calibration) software of Ramsay, can automatically correct the belt scale. After the N value is calibrated, the weighing value can be weighed and accumulated.
Four, drift of zero point and drift of interval, the drift of zero point is generally related to the conveying system, and the reasons for zero drift are:
A. weighed the dust and aggregate on the bridge.
B. materials and clutter cards are in the weighed bridge.
The C. belt conveyer has sticky material.
D. belt tension is not uniform.
E. because of the temperature characteristics of materials and the long-term use of belts, the belt is stretched.
F. failure of electronic measurement components.
The severe overload of the g. load sensor.
The cause of the interval drift
Change of belt tension of conveyer
(2) the change of the sliding or its diameter of a velocity measuring drum...

(2) check regularly whether the spacing is reasonable, and the bolt should not collide with the scale.

(3) a semiannual maintenance is carried out on the connector, and the head is buttered with butter.

(4) it is forbidden to carry out arc welding operation on the scale platform. Please pay attention to the following points: (disconnect the connection between the signal cable and the weighing display controller; the ground wire of the arc welding must be set near the welded part and firmly in contact with the scale body; the sensor can not be used as part of the arc welding circuit).

2. electronic weighing and weighing display controller maintenance

(1) check whether the wiring is loose or broken, and whether the grounding wire is reliable.

(2) the weighing display controller is not used for a long time (for example more than one month), and the electricity should be checked according to the environmental conditions, so as to avoid the impact of moisture or other bad gas erosion on the reliability.

(3) weighing display controller avoids proximity to heat source and vibration source.

(4) there should be no inflammable and explosive gas or dust in the use environment.

(5) no inductive load, such as doorbell, is allowed on the same phase line of the weighing display controller.

(6) the weighing display controller must be cut off for long periods of time, replacing fuse, moving position or removing dust.

(7) the weighing display controller should quickly break off the power if the fault occurs, and then notify the professional department and the personnel to check and arrange, the user may not open the chassis at will, and will not change the internal parts at will.

(8) weighing personnel and instrument maintenance personnel need special training to operate and maintain.

3. electronic weigh - replacement sensor

(1) open the upper cover of the sensor (damaged), jack up the scale, and remove the sensor ground wire.

(2) open the junction box and release the damaged sensor cable from the junction box. Pull out the cable at the end of the sensor. Note: when the wire is drawn, a lead is passed through the scale body so that when the new sensor is replaced, the cable line passes through the scale body and enters the junction box.

(3) referring to the second methods mentioned above, the sensor cable line passes through the scale body and enters the junction box.

(4) fix the cable core wires on the corresponding terminals of the junction box according to the wiring diagram.

(5) release the jack, set up the scale and cover the cover.

(6) after replacing the sensor, the truck scale must be reset and calibrated.

(7) after the sensor has been installed, the excess cables should be tied into bundles and not placed directly on the ground.

(8) in order to ensure consistency and interchangeability of sensors, the sensor cable should not be truncated at will.

(9) in the process of installation and demolition, there should be no scratch or knock sensor phenomenon, and the cable should be well protected.

4. computer maintenance

(1) to ensure that the computer grounding system is good.

(2) strictly prohibit frequent switching, free movement and dismantling of computers.

(3) the computer should be far away from the water source and strong electromagnetic interference.

(4) it is strictly forbidden to use foreign floppy disks at random, so as to prevent infection of viruses.

(5) it is strictly prohibited to strike a keyboard with a hard object, such as a screwdriver.

(6) the engine room should be kept clean and the temperature should comply with the specifications of the machine.

(7) the operator needs to be trained after training.

5. system maintenance

(1) after the installation of the weighing apparatus, the instructions, certificates, installation drawings and other materials should be properly preserved, and they shall be put into use by the local Metrology Department or the national approved Metrology Department.

(2) before the system is electrified, it is necessary to check whether the grounding device of the power supply is reliable.

(3) weighing apparatus should check whether the scale is flexible before use, and whether the supporting parts are of good performance.

(4) the weighing display controller must be pre heated, usually about 30 minutes.

(5) in order to ensure the accurate measurement of the system, the lightning protection facilities should be protected. When the electric welding operation near the weighing device, the scale platform is strictly forbidden to be used as zero line grounding to prevent the damage of electrical components.

(6) for the ground balance in the field, the drainage devices in the foundation pit should be regularly checked to avoid clogging.

(7) keep the junction box dry. Once the wet air and water droplets are immersed in the junction box, the hair dryer can be dried.

(8) in order to ensure the normal metering of weighing instruments, it should be calibrated regularly.

(9) there should be no impact when lifting heavy weights; when measuring heavy vehicle loads, it should not exceed the rated weight of the system.

(10) the axle load of truck scale is related to the capacity of sensors and the distance between sensors and pivots. The general truck scale prohibits the short wheelbase vehicles such as forklifts that are close to the maximum scale.

(11) both the operator and the instrument maintenance personnel need to read the instructions and relevant technical documents before going to work.

Definition of scales
Weighing, as the name suggests, is used to control the air handling and weighing weighing equipment. The crane is lifting and driving the common name. An electronic balance weighing is installed on the crane, is a kind of non-standard scales, usually used in some iron and steel plant, metallurgical factory.
In some iron and steel metallurgy factory, because sometimes because the temperature is too high or the crane lifting height is not enough, the electronic balance can not be used, especially in the special occasions of large tonnage hoisting, large tonnage of electronic steelyard cost increases and more safety is also reduced, lifting height and high temperature limit, the use of hook scale is limited, but it must be measured on the weight lifting work, it is the case, the strength of the individual and the weighing apparatus factory crane factory jointly developed a scale crane (crane scale). But because of the impact process and sensor performance making, weighing (running scale) usually accuracy is not too high, probably at about 0.5%--1%. Therefore, in accordance with national standards, in accordance with the standard three level scale can be used for industrial and commercial use and scales, crane scales (crane scale) can only be classified as grade four scales, so under normal circumstances, weighing (Driving Scale) just for internal settlement or process control.
