The instruction feeding system is a production equipment used in industry to automatically and accurately process different powders or liquid materials in a certain proportion. It usually consists of a Weighing system, weighing control instruments, PLC system, and upper computer. The weighing system includes various equipment such as raw material storage, conveying, weighing and batching, dust removal, and material mixing; The batching method can be reasonably selected based on industry characteristics, production process requirements, and specific material characteristics, such as "incremental" or "subtractive" weighing methods, with multiple working modes including single bucket single material, single bucket multiple material, and multi bucket multiple material. The feeding system uses PLC as the central control area to complete the entire process of weighing and feeding. The PLC central control area sends a signal to activate the corresponding solenoid valve to inject liquid into the reaction kettle, and at the same time, the weighing module starts working. When the amount of liquid in the reaction tank increases to the weight set by the quantitative setting indicator, the central control area receives an action signal from the weighing module and immediately closes the solenoid valve for adding liquid, stopping the addition of liquid. Automatically start the mixing switch, send instructions from the control area, activate the corresponding solenoid valve of the mixer, and start timing according to the programmed timer. The mixer uniformly mixes the solution; When the timer reaches the set value, the control area sends a command to close the solenoid valve and stop stirring.

The weighing and Feeding machine is mainly composed of a weighing scale, pneumatic valve, weighing system, safety valve, weighing module, temperature sensor, control circuit, and intelligent control cabinet. The hopper is designed with a vertical cylindrical weighing scale, and the upper and lower ends are welded with heads. A partition plate is vertically welded from the middle of the lower head to the lower end of the upper head to symmetrically separate the weighing scale; There are silos between the upper and middle upper parts of the partition and the weighbridge, and measuring connection plates are welded on the horizontal plane between the lower part of the partition and the lower head weld. The measuring connection plates are welded to the partition, and there is a gap between them and the hopper. A discharge pipe is welded vertically downward at the center of the measuring connection plate. The discharge pipe of the hopper extends from the lower head and is connected to the inlet of the pneumatic valve. The outlet of the pneumatic valve is connected to the oil collection pipeline through the discharge pipe; There is a weighing control system installed at the lower part of the outer circumference of the scale on the partition. The upper end of the weighing control system is connected to the built-in valve inside the upper head through an electromagnetic valve, and the lower end is connected to the pneumatic valve outside the lower head; There is a liquid distribution pipe in the middle between two silos, and each middle of the liquid distribution pipe is equipped with an inlet liquid pipe. The inlet liquid pipe is vertically led out of the hopper and connected to the outlet of the pneumatic valve. The inlet of the pneumatic valve tee is connected to the inlet liquid pipe; A temperature sensor is installed on the gas-liquid pipeline, and a safety valve is installed on the upper head. The pneumatic valve, weighing system, weighing module, and temperature sensor are connected to the control circuit of the intelligent control cabinet.
