As an important equipment system for automatic control in industrial production, the feeding system integrates sensing technology, driving technology, mechanical technology, interface technology, computer technology and other technologies. It is mainly composed of measuring tank, weighing module, signal amplifier, input and output interface, host (host computer) and so on. In order to meet the needs of dynamic measurement, the weighing module input the address, weight and sensitivity of each weighing module, you can automatically balance the "four corners" or "corners" of the scale, without repeatedly adjusting. The digital system can realize "self-diagnosis", that is, the diagnostic program continuously checks whether the signal of each weighing module is interrupted and whether the output is obviously out of range. If there is a problem, it will automatically display or alarm on the weighing instrument or controller panel, and users can use the keys on the panel to find each weighing module, independently determine the cause of the problem and troubleshoot. Remote management can be realized through the digital metering module, and the computer in the control room can be networked with the computer in the general manager's office. The general manager can check the production situation and production report in real time. The digital weighing module is controlled by frequency converter, which can improve the batching precision, thus improving the quality and stability of the product.

The dosing process of the feeding system is divided into two stages of feeding and unloading. After the dosing starts, the feeding Feeder is started first, and the controller detects and samples the weight of the material in the metering bucket. When the weight of the material in the metering bucket reaches the upper limit set by the dosing, the feeding is stopped. At the same time, the controller detects and samples the weight of the material in the metering bucket. When the weight of the material in the metering bucket (feeding amount) reaches the upper limit set by the batching, the feeding will be stopped. In the unloading stage, the controller starts the unloading feeder, and the material in the metering bucket is discharged to the next level of the feeding equipment. When unloading, the controller detects and samples the weight of the material in the metering hopper. When the weight of the material in the metering hopper reaches the lower limit set by the batching, it feeds the metering hopper again. However, after the second feeding stage begins, the discharge feeder continues to discharge without stopping. Intelligent control management: The control function can choose the system operation mode: loading and unloading linkage, quantitative loading, quantitative unloading, manual operation, formula access, formula selection, etc.
