[0002] Plastic masterbatch is a concentrate made by loading an unusual amount of plastic additives into a resin. It is usually processed with the help of an extruder. Through multiple steps such as feeding, melting, extrusion, and shearing, the raw materials are processed into granular products. After the product is extruded, it needs to be cooled to avoid adhesion between the products. However, before the product is extruded, some unstable and small-particle defective products will appear. This product will be mixed with normal products, which will not only cause a waste of resources, but also require secondary sorting, thereby increasing the processing steps.

[0003] The application number is 202321712682.X. A polymer plastic masterbatch extrusion device relates to the technical field of plastic masterbatch production, which includes: a support frame, an extruder main body is arranged on the support frame, a cooling component and a resistance component are arranged on the support frame and located at the discharge end of the extruder main body, the resistance component includes a partition box fixedly installed on the support frame, a filter plate is arranged at the lower part of the partition box, an inclined plate is fixedly connected to the right side of the partition box, a fan is arranged on the right part of the partition box, and an air outlet cavity is fixedly connected to the output end of the fan. Through the cooling component and resistance component, while providing cooling, the extruded products can also be sorted and filtered, and smaller defective products can be separated from normal products, which facilitates the secondary utilization of resources, reduces the processing steps, and is very convenient to use.

[0004] The above technical solution utilizes a filter plate with mesh to separate smaller defective products, but during the separation process, the plastic masterbatch is easily stuck in the mesh, causing blockage of the filter plate and affecting the separation effect of the defective products. Therefore, the present application provides a plastic masterbatch extrusion device to meet the needs. Utility Model Content
