The two upper delivery pipes 241 are telescopic pipes, and one end rod bodies of the two groups of delivery pipes 241 are penetrated and fixedly connected to each other, and the one end rod bodies of the two groups of delivery pipes 241 that are fixedly connected to each other are respectively penetrated and fixedly connected to the outer walls of both ends of one side of the inclined nozzle 238.

[0023] The above scheme is adopted: the moving trajectory of the rectangular groove plate 235 and the two sliding rods 236 will pass through the limit of the block 237 and perform horizontal reciprocating sliding up and down, and then the sliding rod 236 below can synchronously drive the inclined nozzle 238 and the round square long plate 239 to move up and down, and the passive round square long plate 239 will drive the bellows 240 on the outer walls of the upper and lower ends to perform intermittent expansion and contraction respectively, thereby causing the inner cavity of the two bellows 240 to repeatedly generate negative pressure suction and extrusion pressure. The extrusion pressure will drive the paint that has been drawn into the bellows 240 in advance, and it will be sprayed out from the inclined nozzle 238 with impact force through the corresponding delivery pipe 241, and sprayed onto the surface of the rotating and moving automobile stamping part body 28.

[0026] The working principle and use process of the present invention are as follows: after the motor 22 on the L-shaped support frame 21 is started to drive the screw rod 23 to rotate, the two partition panels 12 are then taken out, and the rotating screw rod 23 drives the slider 24 to perform guided limited translation in the rectangular groove 25, thereby the translational slider 24 will synchronously drive the spur gear, the hook 27 and the automobile stamping part body 28 in the meshing component 1 26 to move horizontally, and the spur gear will mesh with the tooth plate during the passive translation process to generate self-rotation, thereby driving the hook 27 and the automobile stamping part body 28 to move and rotate, thereby facilitating the subsequent comprehensive painting of the surface of the automobile stamping part body 28; At the same time, the rotation of the screw 23 can also drive the connected synchronous belt 29, and through the synchronous belt 29, the rotating rod 231 and the meshing component 232 on the transmission rotating rod 231 are driven to rotate. The meshing component 232 in the rotating state will drive the T-shaped turntable 233 to perform a limited fixed-point rotation on the sleeve plate, thereby driving the handle 234 to perform a sliding rotation in the inner wall of the rectangular slot plate 235, thereby driving the rectangular slot plate 235 and the slide bars 236 installed at the upper and lower ends thereof to move. The moving trajectory of the rectangular slot plate 235 and the two slide bars 236 will pass through the limit of the block 237 and perform a horizontal reciprocating sliding up and down, so that the above-mentioned movement presents a circular to linear motion trajectory, and then the slide bar 236 below can The inclined spray head 238 and the round square long plate 239 are synchronously driven to move up and down reciprocatingly. The passive round square long plate 239 will drive the bellows 240 on the outer walls of the upper and lower ends to extend and retract intermittently, thereby causing the inner cavities of the two bellows 240 to repeatedly generate negative pressure suction and extrusion force. The extrusion force will drive the paint previously drawn into the bellows 240 to be ejected from the inclined spray head 238 through the corresponding delivery pipe 241 with impact force, and sprayed onto the surface of the rotating automobile stamping part body 28. The suction force generated by the bellows 240 will quantitatively draw the paint in the paint box 244 through the suction pipe 242, thereby repeatedly spraying the automobile stamping part body 28 with impact force, and the painting operation can be completed quickly and evenly. The painted automobile stamping parts body 28 will continue to move under the transmission. During the movement, it will pass through the heater plate 13 installed in the inner wall at the top of the spray machine box 1. The heat emitted by the two spray machine boxes 1 can dry the surface paint of the automobile stamping parts body 28 until all the automobile stamping parts body 28 move to the inner wall on one side of the spray machine box 1 close to the machine door 11. At this time, the motor 22 can be paused, the machine door 11 can be opened, and the painted and dried automobile stamping parts body 28 can be manually removed, and then the unpainted automobile stamping parts body 28 can be hung for the next round of painting operation.
