Description

Technical Field

[0001] The utility model relates to the technical field of screw polishing, in particular to an omnidirectional screw polishing device. Background Art

[0002] With the widespread use of plastic molding equipment, screws, as the core components of plastic molding equipment, are also increasingly widely used. Usually, screws need 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 screw after polishing is improved, and the friction between the screw and the material is reduced, thereby improving the conveying capacity of the screw. However, the existing screw polishing methods, usually manual polishing or polishing with a screw polishing machine, have certain limitations;

[0003] In this regard, a Chinese utility model patent with authorization announcement number CN221364329U discloses a screw polishing machine, which relates to the field of screw production technology. The screw polishing machine includes a housing and a motor. The motor is installed on one side surface of the housing. A transmission shaft is installed on one side surface of the motor. A clamp is installed on the outer surface of the transmission shaft. A track disc is installed on the outer surface of the transmission shaft. A transmission track is installed on the outer surface of the track disc. A polishing assembly is installed on one side surface of the inner wall of the housing. When the slider moves, the utility model drives the fixed ring and the movable ring to move on the outer surface of the screw through the support frame. The polishing sponge installed on the inner wall of the fixed ring and the movable ring realizes reciprocating polishing of the screw, thereby solving the problem that the screw polishing machine in the prior art needs to reposition the screw when performing secondary polishing on the screw. The efficiency of reciprocating polishing is higher than that of manual polishing, thereby solving the problem of low efficiency of manual polishing in the prior art.

[0004] The polishing blocks in the existing polishing devices are prone to wear after long-term use, which makes the screw polishing effect worse and the work efficiency lower. Therefore, we propose an all-round screw polishing device to solve the above problems. Utility Model Content
