AI Technical Summary

Technical Problem

The existing glue gun cannot meet the glue application task of disposable slippers of different shapes, resulting in waste of glue and waste cannot be separated and recycled. The residual glue drops when the spray gun is broken, which affects the next glue output.

Method used

An arc-retard scraper set is designed, including a heating runner, a retard gun assembly and a prototypical scraper head module. The reverse spray gun cleans the residual glue through the suction action when the glue is broken. The contoured scraper head is designed according to the shape of the product to reduce glue waste and achieve secondary recycling.

Benefits of technology

It effectively solves the problems of glue waste and residual glue cleaning, reduces the defective yield rate, improves the compatibility and maintenance convenience of equipment, and realizes the secondary recycling of glue.

Abstract

The utility model provides an arc reverse extraction scraper set designed for the disposable slipper industry, which comprises a heating runner, a glue inlet joint is arranged on one side of the heating runner, through an integrated design mode, the size is small, a reverse extraction spray gun and a scraper gluing module can be directly installed on the heating runner, under the condition of high-temperature use, heat transfer is more direct, and the service life of the scraper set is prolonged. Compared with the prior art, heating is faster, the temperature is more uniform and stable, the temperature of the spray gun does not need to be increased deliberately to make up for the problems of insufficient temperature transfer and serious heat loss, it is guaranteed that fluid works within a reasonable use temperature range, and the structural characteristics of hot melt adhesive are prevented from being damaged. When the back-extraction spray gun is closed, the back-extraction spray gun has a back-suction effect, the back-suction effect solves the problem that residual glue and dripping glue exist on a scraper head when glue of the spray gun is broken, the profiling scraper head is made below a heating runner according to the shape of a product, the scraper head is in the shape needed by the product at a glue coating starting point and a glue coating ending point, and waste of glue liquid is reduced.
