[0002] A spray gun is a device that uses the rapid release of liquid or compressed air as a power source. Spray guns are divided into two types: standard pressure and pressurized. There are also pressure spray guns, cascade spray guns, and automatic recovery spray guns. In the industry, spray guns can be directly loaded with paint for use, which is a simple spray gun. They can also be installed in automated equipment, such as automatic glue spraying machines, automatic glue coating machines, automatic paint spraying machines, coating machines, and other spraying equipment.

[0031] Working principle: First, the height adjustment cylinder 3 below the spray gun body 1 is fixed to the spraying line, so that the spray head 7 of the spray gun body 1 faces the workpiece to be sprayed. By activating the electric push rod 9 at the top of the spray gun body 1, the electric push rod 9 pushes the horn cover 8 sleeved on the spray head 7 to move laterally to the left. During this process, several telescopic rods 10 installed between the spray gun body 1 and the horn cover 8 extend adaptively, so that the horn cover 8 is transferred from the tail of the spray head 7 to the nozzle area of ​​the spray head 7, until the horn cover 8 covers the surface of the workpiece to be sprayed, achieving the purpose of limiting the spraying range. It is suitable for small-area targeted spraying operations. The first motor 4 drives the first bevel gear 13 to rotate. Since the spray gun body 1 is connected to the rotating disk 12 on the top of the angle adjustment box 2 via the mounting base 11, and the second bevel gear 14 at the bottom of the rotating disk 12 meshes with the first bevel gear 13, the rotating disk 12 drives the spray gun body 1 to adjust the spraying angle. By starting the second motor 5, the gear is driven to rotate. Since the height adjustment cylinder 3 is guided and connected to the lifting column 15 via the guide rail 17 and the sliding part 18, and the rack 16 on the side of the lifting column 15 meshes with the circular gear 6, and the top of the lifting column 15 is connected to the angle adjustment box 2, as the circular gear 6 drives the lifting rod to extend out of the height adjustment cylinder 3, the lifting rod drives the spray gun body 1 above it to adjust the height.
