Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a raw material crushing device for plastic manufacturing. Background Technology

[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that transform synthetic resins or plastics into plastic products. It is a major production sector in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, finishing and assembly. The latter four processes are carried out after the plastic has been molded into products or semi-finished products, and are also known as secondary plastic processing.

[0003] In existing technologies, when plastics are processed, the plastic raw materials need to be crushed. The general crushing method is to directly drive a single rotating rod at the output end of the motor to rotate, and the rotating rod drives the crushing blades fixedly connected to it to crush the material.

[0004] However, relying solely on a single rotating rod to drive the crushing blades for crushing processing cannot completely crush plastic raw materials, and some materials may leak through the gaps in the crushing blades, thus reducing the crushing quality and effect. At the same time, existing raw material crushing devices do not have automatic dust removal functions, resulting in a large amount of dust being generated during the crushing of raw materials. This dust is dispersed in the air, and workers inhaling the dust poses a health hazard, reducing the environmental protection effect of the raw material crushing device. Utility Model Content
