What are the feeding methods of the central feeding system?

The central feeding system completes uninterrupted unmanned continuous forming operations. The variety of materials can be changed according to the needs, the automation of the coloring process can be completed, and the combination of multi-color materials can be used. The system can regenerate and use the sprue cold material in a fully automatic way, can control all feeding equipment, and avoid the occurrence of blockage in the storage bin. After setting up a central monitoring station to complete full automation, the central feeding system is for It is designed for the production of plastic products in the injection molding workshop.

There are several feeding methods in the hopper of the central feeding system. The spring feeding system, the central feeding system, the automatic feeding system, the centralized feeding system, the automatic feeding system, the vacuum feeding and the compressed air can be selected. Methods such as pipeline transportation and feeding. The following is a detailed introduction to us:

1. Central feeding system equipment: It is mainly composed of fans, suction pipes, storage bins, suction pipes, filters, electric control boxes and other components.

When the hopper of the feeding system needs to be loaded, the fan 2 starts, and passes through the suction pipe 4 and the filter screen 3 to form a negative pressure in the central storage bin; at the same time, the suction connected to the central storage bin and the material box The material pipe 8 sucks the material in the material box into the central storage bin. When a certain amount is sucked in, the feeding relay acts, the central system fan stops working, and the suction operation stops; at this time, the discharge valve is opened, which is the extruder. The hopper feeds then to the effect of the central system.

2. Fully automatic feeding system equipment:

The method of fully automatic air pipeline conveying and feeding is used, which is mostly used in the production and supply of several extruders side by side. In such a relatively large-scale production of extrusion products workshop, the conveying system consists of a general feeding pipeline, which is divided into two parts. Several branch pipes are sent out to feed each extruder hopper respectively. This method relies on compressed air and uses air ducts to transport materials. It occupies a small area, uses few people, and the environment is relatively clean. It can be used to transport pellets and powders.

3. Spring feeding system equipment: it installs a coil spring in a rubber tube, and the spring is directly driven by a motor and rotates at a high speed in the rubber tube. When the hopper needs to be loaded, the motor is started to drive the spring to rotate, and the material is spirally driven to rise by the spring. The upper end of the rubber tube is aligned with the hopper and there is a discharge port, and the material rising to the discharge port is rotated by the spring. Force to throw out the discharge port, into the hopper. This kind of feeding equipment has a simple structure, is easy to operate and repair, and is suitable for the transportation of granules and powders.
