Pneumatic grinding equipment for plastic pressing edge production and processing

Abstract

The invention discloses pneumatic grinding equipment for plastic pressing edge production and processing, and relates to the technical field of plastic product processing devices. The pneumatic grinding equipment comprises a workbench, an annular step is fixedly connected to the workbench, and the annular step is connected with a cover body through a controllable telescopic rod in the prior art; and a sealed annular cavity is formed between the cover body and the annular step when the cover body moves downwards to a limit position, the annular step forming the inner wall of the annular cavity is sleeved with a plurality of to-be-ground plastic pressing edges, a plurality of air inlets and air outlets are formed in the cover body forming the annular cavity, and a refrigerating device is installed in the cover body. When the plastic pressing edges are ground, cold airflow is output from the annular cavity where the plastic pressing edges are placed through the refrigerating device and cools the plastic pressing edges, so that the rigidity of the plastic pressing edges is improved, the deformation degree of the plastic pressing edges is small when the plastic pressing edges are subjected to external acting force in the grinding process, and therefore, burrs and flashes on the plastic pressing edges can be conveniently ground and removed.

Description

technical field [0001] The invention relates to the technical field of plastic product processing devices, in particular to a pneumatic grinding device for plastic edge production and processing. Background technique [0002] Plastic is a kind of polymer material with good plasticity. It is usually used as raw material for injection molding. Under certain temperature and pressure, the molten plastic raw material is cooled and formed in the corresponding mold, so that it can be processed into a shape at room temperature. Stable holding of various plastic products. In plastic products, the plastic blank is a circular plastic part with a rectangular cross section. After the plastic blank is processed and formed, the edge of the plastic blank will produce burrs, which not only affects its appearance but also affects its appearance. Due to the influence of size formation, it needs to be further processed after it is processed and formed, that is, the burrs and flashes are remove...

AI Technical Summary

Problems solved by technology

[0003] The invention proposes a kind of pneumatic grinding equipment for plastic edge production and processing, which aims to solve the problem that the grinding equipment in the traditional technology often only grinds one side of the plastic edge so that the grinding efficiency is low.
