Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to a pelletizing device of a pelletizer used for plastic particles. Background Art

[0002] Plastic granules are widely used in the production of various types of plastic products. The production of conventional plastic granules is carried out through processes such as melting, extrusion, and slitting. In the slitting process, conventional slitting machines use guillotine blades to cut, thereby producing granular plastic granules. However, during the long slitting process of conventional slitting machines, the high-temperature plastic masterbatch is very likely to adhere to the guillotine blades, requiring manual cleaning and maintenance, which not only reduces the production quality of plastic granules, but also increases the maintenance costs of the enterprise.

[0003] After searching, China disclosed a particle cutting mechanism of a plastic particle granulator with patent publication number CN217943906U on December 2, 2022.

[0004] Although the cutter of the above-mentioned prior art solution is not prone to material adhesion during long-term operation, plastic particles are likely to fall into the liquid storage mechanism when the cutter cuts downward, resulting in the need for frequent cleaning and affecting work efficiency.
