Central feeding system

Dongguan Huichuang Plastics Machinery Co., Ltd. The central feeding system, also known as the centralized feeding and processing system, enables centralized processing and enclosed input of raw materials, completely eliminating noise, dust, and heat pollution in the workshop. To ensure continuous and stable machine operation, the system employs imported PLC touch screens and fully computerized automatic control, reducing manual intervention and significantly improving product quality. A system designed for the production of plastic products in injection molding workshops. The central feeding system is specifically designed for the production of plastic products in injection molding workshops, enabling uninterrupted, unmanned, and continuous molding operations. It allows for flexible adjustment of raw material types and combinations of multi-colored materials as needed, automating the coloring process. The system can automatically regenerate and reuse sprue cold material in a fully automated manner, controls all feeding equipment, and prevents blockages in the storage bins. Furthermore, it achieves full automation through the setup of a central monitoring station. Operating Principle The central feeding system uses vacuum conveying to transport plastic raw materials from storage tanks to a centralized dehumidification and drying system via a centralized pipeline network, and then delivers the dried materials to each injection molding machine. The central feeding system adopts a “one machine—one pipe” design, ensuring that air continuously transports the materials throughout the system and preventing re-humidification of the dried materials after dehumidification. At the same time, each delivery line operates smoothly without any blockages occurring. When used in conjunction with a centralized dehumidification and drying system, the system cleans the delivery pipelines after each cycle of dehumidification and drying, ensuring that no residual pellets remain inside the pipelines. This not only prevents re-humidification of the materials but also guarantees consistent material properties when fed into the injection molding machines. Under the effect of vacuum negative pressure, dust originally present in the raw materials is filtered out by a dust filtration system, thereby helping to improve the quality of the molded products.
