[0002] Plastic particles are an important intermediate product in the production process of plastic products, which are usually small granular substances prepared by processing plastic raw materials. Plastic particles are the basic raw materials in the production process of plastic products, usually in the form of particles with relatively consistent size and shape, facilitating storage, transportation and subsequent processing. They are prepared by mixing, melting, extruding, cooling and cutting processes of plastic raw materials (such as resins, additives, etc.).

[0003] In the field of plastic particle production, mixing, cooling and melt extrusion are important production links. Traditional production equipment usually puts raw materials into a mixing device for mixing at one time, then sends the mixed raw materials to a melt extrusion device for processing, and then uses a cutting knife to cut and cool the extruded plastic to complete the production of plastic particles.
