[0006] By adopting the above technical solution, it is convenient to send the sheet metal parts into the spraying room for spraying, avoiding affecting the environment, and the sheet metal parts can be quickly sprayed on both sides to improve the spraying efficiency.

[0007] The annular portion is also provided with an access port for connecting with an external paint spray pump.

[0008] By adopting the above technical solution, it is convenient to transport the paint liquid for spraying.

[0009] The upper end surface of the tooth plate is integrally provided with a slide rail, and the movable frame slides along the slide rail.

[0010] By adopting the above technical solution, it is convenient to move the sheet metal parts.

[0011] The middle part of the gear ring is a hollow structure and is fixed to the annular part through a pipe.

[0015] The beneficial effects of the automobile sheet metal spraying device of the utility model are:

[0016] The sheet metal is hung on the hook, and the driving motor drives the moving frame to move through the lead screw. The movement of the moving frame drives the gear ring to move into the spray chamber at the same time. Because the gear ring is meshed with the gear plate and the gear ring rotates on the moving frame through the annular part, the gear ring can rotate while moving, and the spray pipe rotates synchronously. After the sheet metal enters the spray chamber, the chamber door can be closed, and the paint liquid is transported to the inlet through the pipeline through the external spray pump.
