Working principle and function of control device of centralized feeding system

Centralized feeding system plays an important role in industrial production. By adopting single pipe, sealing circuit design and other methods, the whole system can be ensured to run smoothly without moisture regain and material blocking, which can not only improve the working efficiency, but also ensure the molding quality of plastic products. The following is mainly to introduce the working principle of centralized feeding system:

The control of the centralized feeding system can be basically divided into two parts: the control part and the execution part. The centralized feeder control is the control part, which is the execution part of the centralized feeder control relative to the operator, memory and peripheral.

A connection between the central supply control element and the actuating element is through the control line. The controller sends different control commands to the executive part through the control line. Usually, such control commands are called micro commands, and the actions taken by the executive part after receiving the micro commands are called micro operations.

Another connection between controllability and actuator is feedback information. The actuator reflects the operation status to the control part through the feedback circuit, so that the control element can send a new micro-command according to the status of the actuator, also known as "status test". Inching is a basic set of operations in the execution section.

Through the control device, the centralized feeding system enables the centralized drying, dehumidification, metering, mixing, centralized treatment and closed transportation of raw materials, completely avoiding the waste of raw materials polluted by workshop noise, dust and hot gas, and establishing a modern enterprise image.
