Description

Technical Field

[0001] The utility model relates to the technical field of output adjustment structures of spray guns, in particular to an output adjustment structure of a spray gun for electrostatic powder spraying on metal surfaces. Background Art

[0002] A spray gun is a device that uses liquid or compressed air to release quickly as power. There are two types of spray guns: general pressure type and pressurized type. There are also pressure spray guns, Carle spray guns, and automatic recovery spray guns. Spray guns can be used directly with paint in the industry, that is, a simple spray gun, which can be installed in automated equipment such as automatic glue sprayers, automatic glue coating machines, automatic paint sprayers, coating machines and other spraying equipment. The spray gun includes a gun body and a gun head, and the gun body and the gun head are connected by a connecting mechanism; the gun head includes a nozzle, and a number of metal round steels are welded inside the nozzle; the connecting mechanism includes a flange and a chain pin, and can effectively prevent the gun head from falling off and wearing.

[0003] The output of the spray gun used for electrostatic powder spraying on metal surfaces is particularly important during construction. If the output cannot be controlled, the product requirements will not be met during operation, and the sprayed surface will be too thick or too thin, affecting product quality. At the same time, too thick spraying will cause waste of raw materials and increase production costs. Too thick spraying will increase product quality. In precision instruments, this spraying method may cause the product to be directly scrapped and cannot be used, causing economic losses. Utility Model Content

When in use, the rotating block is rotated, and the output of the spray gun is controlled by controlling the size of the misalignment of the first through hole and the second through hole. The first sight block and the second sight block are provided, so that the output can be controlled more intuitively. Appropriate adjustment of the output of the spray gun can avoid waste of raw materials, increase the aesthetics of the product, and increase product sales. The setting structure is simple, and the output can be controlled by rotating the rotating block. The structure is simple and easy to operate. At the same time, the nozzle, the adjustment component and the connecting shell can be directly disassembled, which is convenient for later maintenance and replacement.

[0018] 2. In the utility model, an anti-blocking component is arranged at the front end of the adjusting component, which can prevent the powder in the connecting shell from being blocked when the nozzle output becomes smaller after adjustment, thereby avoiding extending the production cycle due to blockage, increasing practicality, and having a simple structure.
