The roller weighing Feeder is a combination of weighing sensors, weighing instruments and control systems. A system that achieves the weighing and measurement of the material tank and then controls it. It can be directly connected to the PLC system and terminal control system to achieve multi-process control and automatic control. The weak weight signal output by the weighing module is digitally processed to obtain high-precision weighing data. The software is equipped with rich digital filtering technologies and emergency software to prevent the interference system from losing control, etc. The collection, processing, control and output of signals are realized. The level signal of the hopper is collected. According to the collected data, the operation of the motor, solenoid valve and vacuum tube is controlled through the relay. Meanwhile, the feeding process can be manually controlled through the keyboard. The level information, working status, etc. can be displayed on the LCD screen. The externally expanded storage space is used to store important information such as the conveying, discharging, full material and empty material of the two production lines of the automatic feeder.

The operation process of the automatic feeder is to convey plastic particles into a vacuum tube. During the conveying process, the vacuum tube automatically closes, and when discharging, it automatically opens to send the plastic particles to the discharging funnel. The control system requires a total of two relay controllers, which respectively control the directional valve in the working direction and the production motor. When the air pump of the feeder rotates, the air pump generates negative pressure to form a vacuum airflow. The material is sucked into the suction nozzle, forming a material airflow, which then passes through the suction pipe to reach the material bin of the Feeding machine. The filter completely separates the material from the air. When the material fills the silo, the controller will automatically cut off the power supply, the vacuum feeder will stop working, and at the same time, the silo door will automatically open, and the material will fall into the hopper of the equipment. Meanwhile, compressed air automatically cleans the filter through the pulse back-blowing valve. When the time sensor or the material level sensor sends a feeding signal, the feeding machine will start automatically. The high vacuum generated by the vacuum pump, the vacuum powder feeder of the air pump achieves the transportation of materials by generating high vacuum through the rotation of the air pump. It eliminates the stratification of the conveyed materials and ensures the uniformity of the composition of the mixed materials. It is the preferred equipment for automatic feeding of machinery such as spinning machines, tablet presses, capsule Filling machines, dry granulators, packaging machines, crushers, and vibrating screens. The feeding machine control system sets the parameter values for conveying, discharging, full material, and empty material of two production lines according to the requirements of the feeding process. It can also load the parameter values of the previous process of the system. The basic control requirements of this feeding machine are: One motor is used to control two production lines. It should be capable of detecting the full material status and displaying the conveying, discharging and full material times, with a time error of 0.1 seconds, and have anti-interference capabilities.
