Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, in particular to a grinding and finishing device for plastic products. Background Art

[0002] As a common material in our daily life, plastic is favored by various fields because of its light weight, low cost, easy manufacturing, long service life, safety and convenience. Plastic products need to be processed secondary after production. For example, after the production of plastic pipes, the outer end surface needs to be polished and trimmed with a grinding device to ensure that its size meets the use requirements.

[0003] For example, application number: CN201921543152.0 involves a plastic pipe grinding device, including a base, a grinding frame, multiple rotating structures, multiple limiting structures and a supporting structure are provided on the base, a second motor and a sliding groove and a limiting groove connected to the sliding groove are provided on the grinding frame, a screw and a slider are provided in the sliding groove, the slider is threadedly connected to the screw, one end of the screw is connected to the output end of the second motor, a limiting block matching the limiting groove is provided on the slider, the limiting block is connected to the support plate through a connecting block, a third motor is provided on the top of the support plate, a driving gear is provided at the output end of the third motor, the bottom of the support plate is connected to the grinding roller through a connecting plate, and a transmission gear meshing with the driving gear is provided at one end of the grinding roller. By adopting the above structure, uniform grinding is achieved and the consistency of grinding is ensured. The structure of the whole device is novel and reasonable, easy to operate and use, suitable for grinding pipes of various calibers, wide range of application, and extremely practical.

[0004] As for the existing plastic product grinding device, its grinding and finishing structure is imperfect. After the cylindrical plastic product is formed, a convex structure (such as the water outlet of a pipe, etc.) will be retained on one end. Due to the lack of a limiting structure, during grinding, the grinding roller is likely to collide with the convex structure on the outer end of the plastic product, thereby causing damage to the plastic product. In addition, as for the existing plastic product grinding device, its grinding range is fixed. Therefore, when grinding some longer plastic products, grinding and finishing need to be performed in multiple times, which increases the time cost. Summary of the invention
