AI Technical Summary

Technical Problem

Existing powder coating guns are prone to clogging during the coating process due to particulate matter mixed in with the coating material, resulting in low coating efficiency, cumbersome maintenance, and time-consuming disassembly of the coating head.

Method used

A powder coating gun with an anti-clogging structure was designed. A magnetic block is used to quickly connect the spray head to the spray gun body. The spray head can be quickly replaced by rotating the threaded sleeve and sealing ring. The top column is used to push out the clogging particles to ensure that the inside of the spray head is unobstructed.

Benefits of technology

It enables quick replacement and cleaning of the spray head, reduces maintenance time, improves spraying efficiency, avoids spraying problems caused by particulate matter clogging, and enhances the continuity and efficiency of spraying.
