[0002] Common plastics include general-purpose plastics, engineering plastics, and specialty plastics. With the development of the times and advancements in science, the application areas of plastics are gradually expanding. A plastics processing feeder is a comprehensive system designed to efficiently and accurately feed plastic raw materials into processing machinery for subsequent processing.

[0003] During the use of the feeding device of the existing plastic processing machinery, the plastic raw materials contain particles of different sizes and shapes, and the feeding device is usually unable to effectively screen them. The uneven particle size will lead to uneven heat transfer in the subsequent melting process. Some small particles may melt prematurely, while large particles melt slowly, resulting in uneven melt temperature, thereby reducing the quality of the final product. A reasonable raw material delivery volume helps to maintain the stable operation of the production line, avoid frequent shutdowns and adjustments, and thus optimize the production rhythm. Usually, the raw material delivery volume is adjusted by workers increasing or decreasing the number of injections, which requires workers to operate frequently and adjust according to the production plan, thereby increasing labor costs.
