Gluing method of shoepad and apparatus thereof

Abstract

A method and apparatus for applying gum to shoe pad features that the sheet used to make shoe pad is passed through a gap between a gum applying roller and a pressing roller for applying the gum to itin the dots mode, resulting high air permeability.

Description

Technical field: [0001] The invention relates to the technical field of shoemaking, in particular to a method and equipment for gluing insoles. Background technique: [0002] At present, the most commonly used in the production process of insoles is a kind of adhesive called yellow glue. The production method is to smear the raw material EVA or the midsole of the insole with yellow glue, and this yellow glue is glued to the EVA or the midsole. Then it solidifies into blocks. These glued EVA or midsole boards are finally formed into insoles, and some materials, such as cowhide or other leather materials, are added to the surface of the EVA or midsole boards. When molding, the cowhide or other leather materials are first glued to the EVA or Put it on the midsole plate, put it in the oven and bake it for a certain period of time, then take it out and pass it through a molding machine to form it, and after cooling, cut it into pieces as needed. Because this method of forming i...

AI Technical Summary

Problems solved by technology

Because this method of forming insoles requires high-temperature grilling before the insoles are formed, if the surface material of the insoles cannot withstand high temperatures, quality problems will occur during the grilling process, and the material of the surface materials will be damaged seriously. The surface material of the insole formed by this gluing method is limited by high temperature

In addition, yellow gum contains a diluent (toluene) that is quite harmful to the human body, which will be emitted during the process of gluing and grilling, and long-term inhalation will damage human health.
