Description

Technical Field

[0002] With the widespread use of plastic molding equipment, the screw, as the core component of plastic molding equipment, is also being used more and more widely. Usually, the screw needs to be polished before use. Screw polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the screw to obtain a bright and smooth surface. The polishing process is the last process in screw manufacturing. The surface finish of the polished screw is improved, the friction between the screw and the material is reduced, and the conveying capacity of the screw is improved. However, the existing screw polishing methods, usually manual polishing or using a screw polishing machine for polishing, have certain limitations. Manual polishing has the defect of low efficiency, and the existing screw polishing machine has limited precision, the surface finish of the polished product is not high, the consistency is poor, and only one screw can be polished at a time, and the work efficiency is also low. If the precision of the screw polishing can be improved and its work efficiency can be improved at the same time, and after the polishing is completed, the abrasive attached to the surface of the screw can be cleaned up simultaneously, the applicability of the screw polishing can be greatly improved, and a lot of manpower and material resources can be saved.
