The central centralized feeding system adopts microcomputer centralized automatic control to achieve 24-hour continuous feeding operation of granular materials. Multiple small microcomputers control the coloring process of each molding machine, ensuring accurate measurement, uniform mixing, and flexible color change to meet the requirements of multiple colors and varieties of products. Flexibly adjust the feeding amount according to the production capacity of different molding machines. Multiple supply pipeline designs can ensure diverse requirements for main materials. The system has multiple monitoring and protection functions, ensuring safe and reliable operation. The aliases of the central feeding system include: centralized feeding system, automatic feeding system, etc.

The central feeding system adopts vacuum conveying method, which transports plastic raw materials from storage tanks to the central dehumidification and drying system through a centralized pipeline system, and then transports the dried raw materials to each injection molding machine. The central feeding system adopts a design of "one machine, one pipe" to ensure that the air in the entire system transports the raw materials and prevents moisture regain after dehumidification and drying. At the same time, stable operation and material blockage occur in each transmission. It is used in conjunction with the central dehumidification and drying system, and after the dehumidification and drying cycle, the conveying pipeline will be cleaned to ensure that there are no residual particles in the pipeline. This not only avoids moisture regain of the raw materials, but also ensures 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 formed products.

1、 Efficient: The central feeding system can automatically supply various raw materials to any injection molding equipment in multiple rooms, including drying, color matching, and proportional crushing and recycling of raw materials. It can achieve high automation control, monitoring, and meet the production needs of 24-hour non-stop operation.

2、 Energy saving: The central feeding system is easy to operate and only requires a few people to control the feeding demand of the entire injection molding factory, thereby reducing a large amount of labor costs. Secondly, it reduces the raw material belt and corresponding auxiliary equipment next to the injection molding machine, and improves the utilization of space. In addition, due to the use of central feeding, a significant reduction in the number of standalone equipment has been achieved, resulting in energy savings and reduced maintenance costs.

3、 Personalization: The central feeding system can cater to different users, workshop characteristics, and raw material usage requirements. A plan that can be designed according to actual needs.

4、 Modern factory image: The central feeding system will reduce the pollution of raw materials and dust to injection molding production to a certain extent, thereby maintaining a clean production workshop. The centralized dust recovery system of the central feeding system makes cleaning more convenient, and the environmental protection effect meets the standard of 100000 level clean room operation, reducing noise and ultimately achieving unmanned automated production workshop, establishing the image of modern factory management.

The central feeding system adopts a sealed circuit design with one machine and one pipe, ensuring stable operation of the entire system and preventing plastic moisture regain and material blockage. It is used in conjunction with a central drying machine (dehumidifier) system to allow dry air to re dry the raw materials, preventing the plastic from moisture regain after drying. At the same time, the conveying pipe is cleaned after each conveying cycle to ensure that there is no residual material inside the pipe. While avoiding the moisture regain of raw materials, it also ensures the quality of the raw materials added to the injection molding machine. Under the action of vacuum negative pressure, the original dust in the raw materials is filtered out through the filter (dust collector) system, which is beneficial for improving product quality.
