AI Technical Summary

Technical Problem

Traditional grinding machines rely on manual control during the sole polishing process, which can easily lead to over-polishing, resulting in excessively thin edges or uneven bonding surfaces, thus affecting the quality of the sole.

Method used

Design a grinding machine equipped with a side guard. The side guard is fixedly connected to the grinding wheel to form a physical barrier boundary, protecting areas that do not need to be ground and preventing over-grinding.

Benefits of technology

It improved the pass rate of sole grinding, reduced edge errors, enhanced the consistency and efficiency of bonding surfaces, and reduced the scrap rate.

Abstract

A grinding wheel machine equipped with an edge guard includes a grinding wheel, an output shaft that fixes a grinding wheel, and an edge guard that is annular in shape, acting as an outer cover for the grinding wheel to form a physical barrier boundary. A screw with external threads is fixed to the rear side of the grinding wheel, and a base plate with threaded holes is fixed to the edge guard. The grinding wheel and the edge guard are fixed together by the engagement of the screw and the threaded holes. Compared with the prior art, the technical advantage of this invention is that the edge guard protects areas on the sole of a shoe that do not need to be ground, preventing over-grinding and improving the pass rate.
