Description

Technical Field

[0001] The utility model relates to the technical field of recycled plastic particle manufacturing, in particular to a pelletizer for producing recycled plastic particles. Background Art

[0002] Plastic is a high molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Recycled plastic refers to recycled plastic waste that has undergone a series of physical or chemical treatments to remove impurities and additives, and then processed into recycled plastic particles through heating, granulation and other production processes, and finally used to produce plastic products. Recycled plastic has the advantages of environmental protection and energy saving, reducing waste pollution, and reducing production costs.

[0003] In the production process of recycled plastics, the last step is usually to pelletize the cooled plastic rods. However, most pelletizers use manual feeding during operation, which is inefficient and may cause uneven size of pellets. In addition, plastic pellets may splash out of the machine during the cutting process, or even accumulate inside the machine, making it difficult to collect and even affecting work efficiency.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
