Gluing device for pull-ups with knitted elastic cloth

By designing a special glue-coating structure of knitted elastic cloth in the pull-up trouser glue coating device, only the two sides of the elastic cloth are glued, which solves the problem of hindering the reset of the elastic cloth after hot melt glue fills the holes, and maintains the elastic properties of the elastic cloth.

AI Technical Summary

Technical Problem

During the glue application process of the existing pull-up trouser glue coating device, the holes of the knitted elastic cloth deform and expand when stretched. After the hot melt glue is filled, the holes of the elastic cloth are reset and affected, affecting the elasticity of the elastic cloth.

Method used

A pull-up trouser glue coating device with knitted elastic cloth is designed. By installing a surface roller, a bottom roller and an elastic cloth roller in the processing cover, and two coating rollers are used in the glue coating mechanism to place the two coating rollers on both sides of the rollers. Only the two sides of the elastic cloth are glued to form an intermediate space to avoid hot melt glue filling the holes on the surface of the elastic cloth.

Benefits of technology

It effectively reduces the glue coating area of ​​the knitted elastic cloth and avoids hot melt adhesives hindering the resetting of the elastic cloth holes, thereby maintaining the elastic properties of the elastic cloth.

Abstract

The utility model discloses a pull-ups gluing device with knitted elastic cloth, which comprises a processing cover, a surface layer roller, a bottom layer roller and an elastic cloth roller are arranged in the processing cover, the pull-ups gluing device further comprises a glue box fixedly mounted in the processing cover, a cavity is formed in the glue box, a roller in contact with the elastic cloth is rotatably mounted on the lower side of the glue box, and the elastic cloth roller is arranged in the cavity. And coating rollers are fixedly installed on the two sides of the roller, leaking holes are formed in the positions, located on the upper sides of the coating rollers, of the lower side of the glue box, and bristles making contact with the edges of the leaking holes are installed on the surfaces of the coating rollers. The two coating rollers are located on the two sides of the roller correspondingly, so that only the two sides of the elastic cloth are treated, the situation that the middle is hollow and the two sides are coated with glue is formed, and when the elastic cloth only coated with the glue on the upper side moves to the position between the two pressing rollers, due to the fact that the elastic cloth is knitted elastic cloth, and a plurality of holes are formed in the surface of the elastic cloth, in the extrusion process of the pressing rollers, the elastic cloth does not fall off. The hot melt adhesive part on the surface of the elastic cloth is moved to the lower side of the elastic cloth, so that the surface fabric, the elastic cloth and the bottom fabric are bonded.
