Abrasive disk with automatic screening function

Abstract

The invention discloses an abrasive disk with an automatic screening function. The abrasive disk comprises a supporting frame, a protection groove is fixed to the top of the supporting frame, a grinding groove which vertically slides is formed in the inner wall of the groove, discharging holes which are evenly arranged are formed in the two sides of the grinding groove, a driving device is fixed to the top of the protection groove, a collision device is arranged on the driving device, the bottom of the driving device is provided with an abrasive disk body acting with the grinding groove mutually, a blowing device is rotatably connected to the bottom of the abrasive disk body, the blowing device and the grinding groove are fixedly sleeved, the blowing device is movably connected with the top of the supporting frame, the raw material can be automatically ground, during grinding, the grinding groove can move up and down, the grinding effect between the raw material and the abrasive disk body is better, meanwhile, the ground coating raw material can be blown out, automatic grinding and screening can be achieved, grinding is more convenient, and the machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of raw material screening, in particular to a grinding disc with automatic screening function. Background technique [0002] Paint is a substance that can form a complete film and be firmly bonded to the surface of an object when it is applied to the surface of an object. Early paints were mainly made of natural animal oils (butter, fish oil, etc.), vegetable oils (tung oil, linseed oil, etc.) and natural resins (rosin, lacquer), etc., so paints are also called paints. Since the 1950s, the rapid development of the world's petrochemical industry and polymer synthesis industry has provided a good material basis for the development of the paint industry. Therefore, in addition to a small amount of natural resin and oil, the current paint is mainly made of synthetic resin. for film-forming substances. [0003] After the existing paint raw materials are ground, the ground raw materials are often poured out, which is too ...

AI Technical Summary

Problems solved by technology

[0003] After the existing paint raw materials are ground, the ground raw materials are often poured out. The operation is too cumbersome and the efficiency is low. Therefore, we propose a grinding disc with automatic screening function.
