[0041] Specifically, during the spraying operation, the spraying device adjusts the angle of the movable frame 2 by driving the first electric cylinder 204. After adjusting the movable frame 2, the switch 202 can be turned on to inflate through the air pressure pump 201, and the paint is introduced into the interior of the spray plate 4 through the liquid inlet pipe 203. The spray plate 4 conducts large-area spraying work. During the spraying operation, the spray splash-proof baffle 401 diverts the paint, atomizes it through multiple diversion holes 402, and conducts heating and drying treatment through the constant temperature fan 105 to improve the processing efficiency. Moreover, the reduction motor 601 drives the support pad 5 to rotate, cooperating with the rolling balls at the bottom of the pressure plate 301, so that the automotive trim on the surface of the support pad 5 rotates. While rotating, spraying work is carried out through the two spray plates 4, and the spraying range is wider.

[0042] Working principle: When spraying automotive trim, the automotive trim to be sprayed is placed above the support pad 5. The second electric cylinder 3 is extended to press down the pressure plate 301 to limit and fix the position of the automotive trim. The angle of the movable frame 2 is adjusted by driving the first electric cylinder 204. After adjusting the movable frame 2, the switch 202 can be turned on to inflate through the air pressure pump 201. The air pressure pump 201 introduces the gas into the spray plate 4. Affected by the air pressure, the paint is squeezed in front of the solenoid valve. After the solenoid valve is opened, the paint sprays out through the diversion holes 402 along with the high-pressure air for atomized spraying work. During the spraying operation, the spray splash-proof baffle 401 diverts the paint, atomizes it through multiple diversion holes 402, and conducts heating and drying treatment through the constant temperature fan 105 to improve the processing efficiency. Moreover, the reduction motor 601 drives the support pad 5 to rotate, cooperating with the rolling balls at the bottom of the pressure plate 301, so that the automotive trim on the surface of the support pad 5 rotates. While rotating, spraying work is carried out through the two spray plates 4, and the spraying range is wider. When the automotive trim moves, the damping gasket 302 reduces vibration, and the position of the constant temperature fan 105 is adjusted by adjusting the position of the telescopic plate 503 inside the device bracket 1 and the connecting sleeve plate 502 to adapt to automotive trims of different sizes, thus meeting different types of spraying work.
