AI Technical Summary

Technical Problem

Existing spray dispensing valves are prone to glue overflow when changing glue cartridges, resulting in waste and product damage. Furthermore, the connection is unstable, affecting the consistency of dispensing quality.

Method used

A dispensing assembly with easy-to-replace glue cartridges was designed. It achieves quick disassembly and connection between the glue cartridge and the valve body through magnetic attraction and threaded connection. The ball and spring structure controls the connection and cut-off of the glue flow channel to ensure the stability and consistency of the glue.

Benefits of technology

This technology ensures the stability and consistency of the adhesive solution during the glue cartridge replacement process, avoids spillage and waste, improves the connection stability and assembly accuracy of the dispensing components, and guarantees the consistency and efficiency of dispensing quality.

Abstract

The dispensing assembly comprises a glue supply barrel and a glue inlet block installed on the lower end face of a valve body, the lower end of the glue supply barrel is connected with a glue supply block internally provided with a glue supply runner, a connecting block is installed on the side end face of the end, facing the glue supply block, of the glue inlet block, and a through hole is formed in the glue supply connecting block; a glue supply nut with a first central through hole is installed at the end, close to the glue supply runner, of the through hole, one end of a first spring in the through hole makes contact with the end face of the glue supply nut, a first ball is arranged at the other end of the first spring, and the inner wall of the middle of the through hole is arranged to be a slope face matched with the first ball; a runner hole is formed in the end face of one end of the glue inlet connecting piece, and a glue inlet nut with a second central through hole is installed at one end of the runner hole. The glue supply barrel can be conveniently replaced to continuously supply glue to the valve body, the stability and consistency of glue liquid in the glue outlet runner before and after the glue supply barrel is replaced are kept, and then the consistency of the glue dispensing quality is guaranteed.
