Description

Technical Field

[0001] This utility model belongs to the field of plastic product recycling, specifically, it relates to a plastic product crushing device. Background Technology

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastic. They include all injection-molded, vacuum-formed, and other plastic products. Injection-molded plastic products need to be deburred or de-burred. The scraps generated during this process need to be shredded and ground into smaller pieces when recycling scraps or defective injection-molded products.

[0003] Compared to the plastic product crushing device disclosed in CN221187235U, this device includes a crushing device housing with an inlet at the top and an outlet at the bottom. An operating box is located on one side of the housing. A first crushing rod is rotatably connected inside the housing. Multiple crushing blocks are evenly distributed on the surface of the first crushing rod. Both ends of the first crushing rod have first drive shafts, and the outer wall of the first drive shaft near the operating box has multiple drive teeth. The first crushing rod effectively crushes the plastic. When the plastic enters the inlet, it is squeezed and crushed by the continuously rotating first crushing rod. The plastic then falls onto multiple second crushing rods for secondary crushing, resulting in better crushing effect, reduced plastic blockage, and improved work efficiency.

[0004] The aforementioned comparative documents, while utilizing the first and second crushing rods to perform secondary crushing of recycled plastic products and scraps entering the casing, suffer from several drawbacks. Firstly, when the plastic product is too large, it may become stuck in the feed inlet and fail to enter the crushing chamber. Secondly, when the injection-molded part is circular, the two first crushing rods may have difficulty finding a point of contact, causing the circular plastic product to rotate between the first crushing rods, thus affecting efficiency. Therefore, this utility model is proposed to address these issues. Utility Model Content
