[0002] Plastic pellets are a type of granular plastic material, usually used as semi-finished raw materials for the production of plastic products, and are made through processes such as melting, extrusion, and granulation. These pellets are easy to store, transport, and process, and are an indispensable raw material in the production of plastic products. Plastic pellets can be divided into many types, including general-purpose plastics, engineering plastics, thermosetting plastics, and special plastics such as functional polymer plastics.

[0003] The utility model with patent number CN212400293U relates to the technical field of plastic processing equipment, specifically, to an extruder feeding device, including a feeding barrel, a barrel cavity is provided in the feeding barrel, a bottom sleeve is provided at the bottom end of the feeding barrel, a through opening is provided at the outer surface of the feeding barrel, an inner barrel is sleeved in the barrel cavity, a tooth groove is provided on the inner barrel, a rotating motor is provided on the side of the feeding barrel, a gear is installed at the end of the output shaft of the rotating motor, and a scraper is provided inside the feeding barrel. The extruder feeding device, through the inner barrel provided inside the feeding barrel and the rotating motor outside and the scraper provided inside the feeding barrel, when the rotating motor drives the inner barrel to rotate in the feeding barrel through the gear during operation, the scraper can scrape off the plastic particles adhering to the surface of the inner barrel, so as to prevent the feeding barrel from being blocked due to the plastic adhering to the inner wall of the feeding barrel after high-temperature baking.

[0004] When processing plastic pellets, it is necessary to continuously feed raw materials to the extruder. Although the device in the above patent prevents the pellets from sticking to the barrel wall, the raw material feeding rate is relatively random, and it is difficult to adjust the speed of feeding raw materials according to needs, which reduces the feeding efficiency. For this reason, we provide an anti-blocking plastic pellet extruder servo feeding mechanism to solve the above problems. Utility Model Content
