AI Technical Summary

Technical Problem

Traditional hot melt adhesive coating equipment has shortcomings in temperature control and precise adhesive replenishment, which leads to a drop in hot melt adhesive temperature, poor fluidity, easy clogging, and affects production efficiency and coating quality.

Method used

A hot melt adhesive coating device including a movable heat-insulating adhesive applicator was designed. By setting the heat-insulating adhesive applicator above the slit extrusion die, the temperature of the hot melt adhesive is maintained by the heating element, and the sliding mechanism is used to achieve precise adhesive applicator application, ensuring the consistency of temperature and amount of hot melt adhesive in all areas of the die.

Benefits of technology

It effectively solves the clogging problem caused by the drop in hot melt adhesive temperature, improves coating quality and production efficiency, and achieves efficient and uniform hot melt adhesive replenishment.

Abstract

The application discloses a hot melt adhesive glue-filling coating device, which comprises a rack, a slit extrusion die, a heat-preservation glue-filling device, a carrier plate and a coating roller. The heat-preservation glue-filling device comprises a heat-preservation shell, a heating element arranged in the heat-preservation shell, a glue injection port matched with a glue inlet of the slit extrusion die and a driving device for controlling the moving speed and position of the heat-preservation glue-filling device. The heat-preservation glue-filling device continuously injects hot melt adhesive into the slit extrusion die through the glue injection port during the moving process. The hot melt adhesive is extruded through the slit extrusion die and coated on the coating roller, and then the coating roller transfers the hot melt adhesive to the surface of a substrate on the carrier plate. The hot melt adhesive coating device realizes efficient glue filling of the hot melt adhesive through the innovative design of the heat-preservation glue-filling device, and effectively solves the problems of blockage and coating quality caused by the temperature drop of the hot melt adhesive in the traditional glue supply mode. The heat-preservation glue-filling device continuously injects hot melt adhesive into the slit extrusion die through the glue injection port during the moving process, thereby ensuring the temperature uniformity of the hot melt adhesive and improving the coating quality.
