leather shoe grinding wheel

Abstract

The invention discloses a leather shoe grinding wheel. The grinding wheel comprises an inner grinding wheel and an outer grinding wheel; the inner grinding wheel comprises an inner shaft sleeve and an inner wheel disc arranged on the inner shaft sleeve in a sleeving manner, the outer grinding wheel comprises a grinding wheel base and an outer wheel disc arranged on the periphery of the grinding wheel base in a sleeving manner, grinding faces are arranged on the circumferences of the inner wheel disc and the outer wheel disc, the interior of the grinding wheel base is circumferentially connected with a nut sleeve in a limiting manner, the inner shaft sleeve is provided with a stud segment in an extending manner, and penetrates a center hole of the inner wheel disc to be in threaded connection with the nut sleeve, a circumferential-limiting axial one-way moving fit structure is formed by the inner shaft sleeve and the inner wheel disc, an open cavity matched with the inner wheel disc in outer diameter is formed in the grinding wheel base, the inner wall of the open cavity is smooth and flat, and the periphery of the inner wheel disc achieves the aim that the periphery of the inner wheel disc is locally or completely exposed out of the outer wheel disc along with relative movement of the inner shaft sleeve and the nut sleeve. Through relative axial movement of the inner grinding wheel and the outer grinding wheel, the width of the grinding face of the inner grinding wheel can be adjusted, edges with different widths, front edges with different heights, uppers, soles and the like can be ground, efficiency is improved, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of shoe processing and beautifying equipment, in particular to a leather shoe grinding wheel for grinding leather shoe edges and sticky bottoms (or double bottoms). Background technique [0002] In traditional crafts, leather shoes consist of an upper and a sole. When the upper and the sole are bonded or sewn together, a leather edge of a certain width is reserved at the edge for inward folding, through which the leather edge is connected and fixed to the sole. But usually in order to make the connection between the upper of a shoe and the sole more tightly and firmly, before bonding, the leather edges on the upper surface of the shoe need to be polished and polished; The post-processing technology of shoes and boots" is aimed at a kind of shoes with leather welts. After the upper and sole are shaped, a series of post-processing is required for the leather welts: use a grinding wheel to polish the sole side ...

AI Technical Summary

Problems solved by technology

Because the conventional grinding wheel has a fixed grinding surface, it can only be used for grinding leather shoes with a certain edge width. Its application range is narrow, and it cannot be used for efficient grinding for leather edges with different widths, nor can it be used for both uppers and soles at the same time. polished
