The feeding system mainly consists of a central control console, storage units (such as storage tanks and hoppers), a conveying pipeline network (main and branch pipelines), auxiliary modules (such as a central dehumidification and drying system, mixing device, and dust collector), and an intelligent control system (such as a PLC and sensors).
The feeding system uses pneumatic conveying, primarily including two modes: vacuum negative pressure conveying and positive pressure conveying. Vacuum negative pressure conveying utilizes the negative pressure generated by a vacuum pump to suck up and transport materials. Its workflow typically includes stages such as air extraction, material conveying, air-material separation, and material discharge.
The system employs centralized automatic control via a microcomputer (such as a PLC), coupled with a human-machine interface (HMI), enabling 24-hour continuous feeding of granules, independent and precise control of the coloring process of multiple molding machines, raw material status monitoring, fault diagnosis, and safety protection functions.
