[0002] Plastic pellets refer to granular plastics, which are the raw materials for storage, transportation and processing of plastics in the form of semi-finished products. In daily life, recycled pellets can be used to make various plastic bags, toys, furniture, stationery and other daily necessities and various plastic products. The value and versatility of plastics made into pellets mainly come from their excellent chemical resistance, and their cost is also relatively low. Whether in transportation or storage, they are far superior to the cost required for finished plastics.

[0003] The production of plastic particles has always been a matter of great concern to various manufacturers. The equipment required for the production of plastic particles is usually a pelletizer. The plastic particles cut by the pelletizer need to be transported to the storage tank and then discharged and packaged. Among the plastic particles cut by the pelletizer, there will inevitably be a small number of uneven sizes, which will affect the overall quality of the plastic particles. At the same time, during granulation, there will be a lot of dust on the plastic raw materials, which will also affect the granulation quality of the particles. At the same time, unqualified granulation density is also a problem that needs to be paid attention to in granulation production. Summary of the invention
