Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to a hot melt adhesive casting machine. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. It is popular because the product itself is solid, easy to package, transport, store, solvent-free, pollution-free, and non-toxic; and has the advantages of simple production process, high added value, high bonding strength, and fast speed. Hot melt adhesive is often needed in the processing of shoe uppers. Since hot melt adhesive is thermoplastic, if the hot melt adhesive film is not compounded with the mesh during production, it needs to be completely melted and reprocessed to combine it with the mesh later. Therefore, hot melt adhesive casting machines are often used in the processing of hot melt adhesive shoe uppers.

[0003] CN202121298104.7 introduces a hot melt adhesive casting machine for upper processing. By heating, the mesh cloth stretched on the first tensioning roller and the second tensioning roller can gradually sink into the hot melt adhesive film. After smoothing by the smoothing roller, the required composite hot melt adhesive film can be obtained. The combination of the two can be achieved without making the hot melt adhesive enter a molten state. It has practical significance and promotion value, and is expected to produce good economic benefits. However, the casting machine is not convenient for limiting the hot melt adhesive according to the width of the upper processing. After the hot melt adhesive is heated and melted, the two ends tend to collapse and flow to both sides, which easily affects the effect of the upper processing. Utility Model Content
