Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a spray gun structure of a spray machine which can prevent paint from splashing. Background Art

[0002] Paint splashing is a common problem in spraying operations, which not only affects the coating quality but may also have adverse effects on the environment and operators. Traditional spray gun structures often cause paint splashing during the spraying process due to improper control of the paint spray angle and pressure or unreasonable nozzle design. Therefore, designing a spray gun structure that can effectively prevent paint splashing is of great significance for improving spraying efficiency, ensuring coating quality and protecting the operating environment.

[0003] Reference announcement number CN221016870U is a spray gun structure for preventing paint from splashing, which includes a gun body, a trigger movably connected to one side of the gun body, a paint inlet connected to the top of the gun body, and an air interface connected to the bottom of the gun body; it also includes: an anti-splash cleaning mechanism installed above the atomizing nozzle; a collecting assembly installed below the atomizing nozzle, the spray gun structure for preventing paint from splashing is equipped with an anti-splash cleaning mechanism, which drives the first gear to rotate through the output end of the micro motor when the device is in use, and then drives the first gear to rotate through the second gear. The meshing of the first gear and the second gear drives the atomizing nozzle to rotate, and at the same time drives the scraper to rotate inside the protective cover to clean the inner wall of the protective cover. The scraped spray liquid falls into the liquid receiving tank at the bottom through the discharge trough opened at the bottom of the protective cover, completing the cleaning and collection of the residual spray liquid inside the protective cover. The collection efficiency is higher and the residual spray liquid in the protective cover is prevented from solidifying and being difficult to clean. According to the above, although the spray gun structure can be well applied, it is usually not convenient to adjust the liquid inlet rate of the paint, and thus it is difficult to spray the object as needed, and it needs to be improved. Utility Model Content

[0004] The purpose of the present utility model is to provide a spray gun structure for a sprayer that prevents paint from splashing, so as to solve the problem in the above-mentioned background technology that although the spray gun structure can be well applied, it is usually not convenient to adjust the liquid feeding rate of the paint, and thus it is difficult to spray objects as needed.

[0005] The top of the spray gun is provided with a nozzle, and the nozzle is provided with a nozzle, and the nozzle is provided with a nozzle, and the nozzle is provided with a nozzle, and the nozzle is provided with a nozzle.

[0006] Preferably, an air inlet is provided on the outer wall of one side of the spray gun handle body, and the air inlet is provided so as to be connected to the air supply pipe of the spray machine.

[0007] Preferably, a protective cover is movably connected to the outer wall of the spray nozzle outside the spray port, and a driven gear is fixed to the outer wall of the protective cover. The provision of the protective cover can reduce the splashing phenomenon generated when the paint is sprayed.

[0008] Preferably, a positioning frame is provided at the top end of the spray nozzle, and a rotary driving member is installed on the outer wall of the positioning frame, so that the driving gear can be driven to rotate through the arrangement of the rotary driving member.

[0009] Preferably, scrapers are provided on the outer walls of the spray nozzles on both sides of the spray port, and the outer walls of the scrapers touch the inner wall of the protective cover. The scrapers are provided to scrape and clean the inner wall of the protective cover.

[0010] Preferably, a rotating shaft is installed at the output end of the rotating drive member through a coupling, and a driving gear is provided at the end of the rotating shaft away from the rotating drive member. The driving gear and the driven gear are engaged with each other, so that the driven gear is driven to rotate when the driving gear rotates.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the spray gun structure for preventing paint from splashing can not only adjust the rate at which paint enters the interior of the spray gun body as needed, thereby improving the convenience of using the spray gun structure, but also reduces the phenomenon of paint splashing when spraying, thereby ensuring the spraying effect of the spray gun structure on the object when using it, and reduces the phenomenon of paint adhering to the inner wall of the protective cover;

[0012] (1) The telescopic driving member drives the linkage shaft to rotate through the driving arm, so that the linkage shaft drives the tube core located inside the feed tube to rotate, and the opening and closing size of the tube core can be adjusted to adjust the speed of the paint entering the interior of the spray gun body as needed, thereby improving the convenience of the spray gun structure when used;

[0013] (2) By installing the protective cover on the outer wall of the spray nozzle outside the spray port, the protective cover can shield the paint sprayed from the spray port, thereby reducing the splashing phenomenon when the paint is sprayed, so as to ensure the spraying effect of the object when the spray gun structure is used;

[0014] (3) The driving gear is driven to rotate by the rotating drive member via the rotating shaft. Since the driving gear and the driven gear are meshed with each other and the diameter of the driving gear is smaller than that of the driven gear, the driving gear drives the outer wall of the protective cover located at the spray nozzle to rotate slowly through the driven gear, and the scraper can scrape and clean the inner wall of the protective cover, thereby reducing the phenomenon of paint adhering to the inner wall of the protective cover.
