Description

Technical Field

[0001] The utility model relates to the technical field of shoe last manufacturing, in particular to a grinding device used for shoe last manufacturing. Background Art

[0002] The shoe last is the mother of the shoe. It is the molding mold of the shoe. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits the foot and whether it can protect the foot. Therefore, the design of the shoe last must be based on the foot shape, but it cannot be the same as the foot shape, because the foot changes in shape, size, stress, etc. when it is static and in motion. In addition, the shoe variety, style, processing technology, raw and auxiliary material properties, wearing environment and conditions are also different. The shape and size of each part of the shoe last cannot be exactly the same as the foot shape.

Regular cleaning of the cleaning box can avoid the accumulation of debris.

[0004] This patent uses a U-shaped block to fix the shoe last. However, when the patent is sanded, since only the U-shaped block is used to fix the shoe last, it is very easy to cause the shoe last to shake during sanding, resulting in inaccurate sanding position, which is very troublesome.
