Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shoe production and processing, and particularly relates to a clamping device for grinding the outer side of a shoe sole. Background Art
[0002] When producing shoes, since there may be some minor unevenness or size deviations in the production process, grinding can make the outside of the sole smoother. At the same time, grinding the outside of the sole can remove excess material and burrs, so that the sole and the upper can be closely combined in the subsequent bonding process, improving the overall stability and comfort of the shoe. In addition, grinding can remove defects, scratches or rough surfaces on the outside of the sole, making its appearance smoother and more beautiful, thereby improving the grade and market competitiveness of the product. It is necessary to grind the outside of the sole of the shoe, and when grinding the outside of the sole of the shoe, there are usually manual grinding, machine grinding and hot press grinding. When performing manual grinding, sandpaper, grinding wheels or other grinding tools are mostly used to manually grind the outside of the sole. When performing machine grinding, a professional sole grinder is used to grind the sole by a rotating grinding wheel or grinding head. For soles of some special materials, hot press grinding is used. The sole is heated to soften it, and then a mold or a pressure wheel is used to shape and polish the outside of the sole. When polishing the outside of the sole of ordinary shoes, it is usually done by mechanical polishing. During polishing, in order to facilitate the operation of the staff, the edge of the sole of the shoe will be clamped and limited to keep the shoe stable during polishing. Currently, common clamping devices mostly fix the sole with various clips. Although this fixing method can provide stability for the shoe when the shoe is polished, it will cause clamping marks at the clamping point of the sole, affecting the quality of the shoe. At the same time, the clamping surface of the clip may cause damage to the sole of the shoe. Utility Model Content
