By starting the drive motor, the driving wheel can be driven to rotate, and then the driving wheel can drive the driven wheel to rotate through a belt, and the driven wheel can drive the connecting rod to rotate, so that the connecting rod can drive the powder storage tank and the spray gun to rotate to achieve powder spraying at different angles, avoiding the problem that the angle of the spray gun cannot be adjusted, resulting in the need to manually adjust the position of the spray gun when objects at different positions need to be sprayed, thereby solving the problem that manual adjustment is time-consuming and labor-intensive, and will greatly delay the work efficiency of the staff, and improving the practicality of the device.

[0004] In the above technical solution, in the existing powder spraying equipment, the powder is often blocked during the transportation process due to factors such as uneven particle size, improper humidity control or unreasonable design of the conveying pipeline.
