AI Technical Summary

Technical Problem

The nozzle assembly of existing hot melt adhesive spray guns is prone to displacement when subjected to external force from other directions, and the connecting bolts are prone to loosening in intermittent spraying mode, resulting in uncontrolled spraying of hot melt adhesive.

Method used

The nozzle assembly design incorporates a spraying component that connects to the mounting component via a snap-fit ​​groove. This snap-fit ​​groove distributes the impact force of the high-pressure hot melt adhesive, and multiple directional limiting functions reduce displacement and loosening.

Benefits of technology

It improves the reliability of the nozzle assembly, reduces uncontrolled hot melt adhesive spraying, facilitates the installation, replacement and maintenance of the adhesive spraying parts, and enhances the overall reliability and maintenance efficiency of the spray gun.
