Feeding system (centralized feeding system)

Feeding system (centralized feeding system)
The feeding system is designed for the production of plastic products in the injection molding workshop, achieving uninterrupted unmanned continuous molding operations. The variety of raw materials and the combination of multi-color materials can be changed as needed to achieve automation of the coloring process. The system is capable of regenerating and using cold materials from the injection port in a fully automated manner, controlling all feeding equipment and preventing blockages in the storage bin. It achieves full automation by setting up a monitoring console.
The 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 feeding system include centralized feeding system, automatic feeding system, etc.

Composition of the feeding system:The system consists of a control panel, pulsating dust collector, filter, fan, branch station (raw material selection rack), drying hopper, dehumidifier, micro motion hopper, electric eye hopper, cut-off valve, cut-off valve, pipeline, etc.

Working principle of feeding:
The feeding system adopts vacuum conveying method, which transports plastic raw materials from the storage tank to the dehumidification and drying equipment through a centralized pipeline system, and then transports the dried raw materials to each injection molding machine. The feeding system adopts“ One machine, one tube; The design method ensures 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 a dehumidification and drying system. 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 consistent 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.
Characteristics of the feeding system
(1) Efficient: The feeding system can automatically supply various raw materials to any injection molding equipment in multiple rooms, including drying treatment, color matching treatment, and proportional crushing and recycling of materials. It can achieve high automation control, monitoring, and meet the production needs of 24-hour non-stop operation.
(2) Energy saving: The 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 feeding methods, a corresponding reduction in the number of standalone equipment has been achieved, which saves energy and reduces maintenance costs.
(3) Personalization: The feeding system can cater to different users, workshop characteristics, and raw material usage requirements. We can design customized solutions according to actual needs.
(4) Modern factory image: The 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 feeding system is equipped with a centralized dust recovery system, which is more convenient to clean and has an environmental protection effect that meets the requirements of a 100000 level clean room operation, reduces noise, and ultimately achieves unmanned automated production workshops, establishing the image of modern factory management.
Introduction to the configuration of the feeding system
Console features:
