The automatic feeding system picks up the weight through the pressure weighing module, amplifies and filters the picked up weight signal, enters into the A/D converter for analog-to-digital conversion, and then sends it to the microcontroller to analyze and process the signal, and outputs the result to the industrial control through the RS232C communication serial port, and at the same time, makes the corresponding reaction and performs the corresponding operation according to the result of the signal.
020-34563445The feeding system mainly realizes the automatic control of the whole system through the Electronic scale, and mainly completes the functions of automatic feeding, discharging, transporting, mixing and stirring of materials. It adopts the centralized control mode of industrial computer batching, which consists of a host and several slaves connected through the network, and the host gives the control task to each slave to complete.
Collective control of dosage through the pressure weighing module for the weight of the pick-up, and pick-up weight signal amplification, filtering, into the A/D converter for analog-to-digital conversion, and then sent to the microcontroller for signal analysis, processing, and the results of the RS232C communication serial port output to the industrial control, and at the same time, according to the results of the signal to make the appropriate response and perform the corresponding operation.
The dosing process and control requirements include feeding, material transportation, mixing and discharging. Each raw material reactor bank has a complete feeding system and a discharging system, which do not interfere with each other. Prior to dosing start-up, the staff needs to establish the raw material recipe and material proportioning program.
When the dosing starts, the feeding system will feed the material according to the set program and the feeding ends. When the raw material reactor is discharging, the material is discharged by detecting whether the material flow reaches the set value, and when the material reaches the set value, the discharging valve will be closed to complete the discharging.
After the process is completed, the material is transported to the corresponding intermediate reactor through the conveyor belt. After transportation, the materials are mixed and stirred in the intermediate reactor.
After mixing in the intermediate reactor, the material reaches the conveyor belt through the discharge valve and enters the mixing reactor through the conveyor belt.
At the end of the step, the material reaches the mixing reactor and starts mixing and stirring. After mixing, the unloading system is activated and the material starts to be unloaded through the unloading valve.
