Hopper Automated Dosage System
The automatic batching system of the hopper is designed based on the multi-station control requirements, selecting the core of the system control circuit, the weighing sensor, the proportional valve, and the peripheral circuits. The weighing system mainly consists of the weighing module, the material tank, the pneumatic conveyor, and the gas pressure control proportional valve with feedback function. To enhance the stability and reliability of the system, by comparing the input signal and the output signal (pressure) difference, the supply pressure is continuously adjusted under the action of the internal control loop, so that the output pressure is basically equal to the set value. And it is transmitted to the PLC through the Modbus protocol.
