How does a high-precision multihead weigher work efficiently? In order to ensure the normal and accurate operation of the high-precision multihead weigher, the following key points must be paid attention to in the whole process of installation and application: 1) The multihead weigher platform is reasonably and reliably installed and fixed: because the weight sensor is an elastic deformation component, External vibration will affect it. The most taboo in the application of high-precision multihead weigher is the vibration hazard of the natural environment. Therefore, when installing the scale body, it should be ensured that the scale body can be protected from vibration hazards as much as possible; 2) There should be no cyclone fluidity in the natural environment: In order to better improve the weighing accuracy, the sensor selected by the multihead weigher specified by the high-precision regulations is very smart, and all movements will have certain harm to the weight sensor. Therefore, using the indoor airflow of the natural environment to install the multihead weigher is one of the effective ways to ensure the normal operation of the high-precision multihead weigher; 3) Scale body connection: the upper and lower conductive soft connections should be light and soft to prevent the upper and lower machines The equipment has an impact on the multihead weigher. The most ideal raw material used before is smooth and soft satin; 4) The distance between the hopper and the silo: the less the connection distance between the large hopper and the upper silo, the better, especially for these adhesions For raw materials with strong properties, when the connection distance between the large hopper and the upper silo is longer, the larger the raw material adheres to the wall thickness, when the raw material on the wall thickness adheres to a certain level, once it falls, it is a multihead weigher. Very large influence; 5) Try to avoid connection with the outside: Whenever the external net weight of the multihead weigher scale body must be kept stable, the purpose is to better reduce the harm of the external interaction force to the scale body; 6) Make up The feeding rate should be fast: in order to make the feeding rate as fast as possible, it is necessary to ensure the smoothness of the feeding during the whole feeding process. For raw materials with poor circulation, in order to avoid their railway bridges, the best solution is to add mechanical stirring to the large hopper. The biggest taboo is cyclone arch breaking, but the stirring cannot be operated all the time. The most ideal is the mixing and The whole process of feeding should be consistent, that is, the same as the feeding gate valve; 7) The lower limit value of feeding and the upper limit value of feeding should be set appropriately: the guideline for setting is that the raw materials are between the two quantities here. The apparent density in the silo is basically the same. This can be obtained by carefully observing the frequency transition of the soft starter. When the apparent density of the raw materials in the silo is basically the same, most of the frequency transition of the soft starter is not large.
The lower limit value of feeding and the upper limit value of feeding are suitable to improve the linearity of the whole feeding process. As mentioned earlier, the multihead weigher is in static data operation during the feeding process. If the feeding can be maintained The frequency basis of the front, rear, left and right soft starters will not change, and the measurement accuracy of the whole feeding process is also largely guaranteed. In addition, under the condition of ensuring that the apparent density is basically the same, try to avoid the frequency of feeding, that is, try to add more material each time. These two are contradictory and should be taken into consideration.
This is also the basis for ensuring the precision of the whole feeding process; 8) The time setting of the feeding time should be appropriate: the guideline for setting is to ensure that all raw materials have already fallen on the scale body, and the less the setting time, the better it is good. It has already been said that the multihead weigher is in static data manipulation during the feeding time, so the less time the better. This time can also be obtained by careful observation. In the adjustment stage, the time can be set longer first, and observe how long the total weight on the scale can not fluctuate (not easy to increase) after each feeding is completed. tends to be stable (the total weight on the scale body decreases steadily), then this time is the appropriate feeding time.
