What is a central feeding system?

1. What is a central feeding system?

The central feeding system is designed for the production of plastic products in the injection molding workshop, realizing uninterrupted unmanned continuous molding operations. The combination of raw material varieties and multi-color materials can be changed as needed to realize the automation of the coloring process. The system can regenerate and use cold materials at the injection port in a fully automatic manner, can control all feeding equipment, and prevent the occurrence of blockage in the storage bin. It is fully automated by setting up a central monitoring station.

The central feeding system adopts microcomputer centralized automatic control to realize 24-hour continuous feeding of pellets. Multiple small microcomputers control the coloring process of each molding machine respectively, with accurate measurement and uniform mixing, and can flexibly change colors to meet the requirements of multi-color and multi-variety products. According to the production volume of different molding machines, the feeding amount can be flexibly changed. Multiple feeding pipelines are designed to ensure the requirements for diversified main materials. The system has multiple monitoring and protection functions, and works safely and reliably.

2. Working principle of the central feeding system

The central feeding system adopts vacuum transmission to transport plastic raw materials from the storage tank to the central dehumidification and drying equipment through a centralized pipeline system, and then transports the dried raw materials to each injection molding machine. The central feeding system adopts the design of "one machine, one pipe" to ensure that the air of the entire system transports the raw materials to prevent the raw materials from rehumidifying after dehumidification and drying. At the same time, each conveying operation is stable and there is no material blockage. It is used in conjunction with the central dehumidification and drying system. After the dehumidification and drying cycle, the conveying pipeline will be cleaned to ensure that there is no residual pellets in the pipeline. While avoiding the rehumidification of the raw materials, it also ensures the consistency of the performance of the raw materials added to the injection molding machine. Under the action of vacuum negative pressure, the original dust in the raw materials will be filtered out through the dust filtration system, which helps to improve the quality of the molded products.
