[0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 types and subdivided into several thousand types. Common plastic particles include general-purpose plastics, engineering plastics, and special plastics. General-purpose plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. Engineering plastics: nylon, polytetrafluoroethylene, polyformaldehyde, polycarbonate silicone, etc. Special plastics: thermosetting plastics, functional polymer plastics. PVC pellets need to be colored during their production process, and a coloring device is required. When the coloring device is used, the pigment and PVC pellets are put into the coloring device, and then the two are stirred to achieve the coloring of the PVC pellets. This method requires a long stirring time and the coloring efficiency is not high enough. Therefore, a PVC pellet coloring device is proposed to improve efficiency. Utility Model Content
