[0021] In one embodiment of this application, the moving component includes a belt conveyor 4, a vacuum suction cup 5 disposed on the belt conveyor 4, and a vacuum pump 13. The inner cavity of the vacuum suction cup 5 is connected to the air inlet of the vacuum pump 13 through a vacuum tube. The vacuum tube can be made of corrugated pipe. The vacuum suction cup 5 is adapted to the slot 12. When the aluminum profile is tightly attached to the top of the vacuum suction cup 5, the operation of the vacuum pump 13 enables the vacuum suction cup 5 to achieve a negative pressure connection with the aluminum profile, and the belt conveyor 4 can drive the aluminum profile to move.

[0022] The spraying cavity is provided with a spraying component 16 in the middle. The spraying component 16 is the prior art. In one embodiment of this application, the spraying component 16 is disclosed in the authorized patent document with application number CN202322648579.X, and will not be described in detail here.

[0023] Two sets of baffles 3 are provided on both sides of the spraying component 16. A spacer groove adapted to the aluminum profile is provided between the two sets of baffles 3. The baffles 3 can divide the spraying cavity into a feeding area, a spraying area and a discharging area. The spraying component 16 is located in the spraying area, and the baffles 3 can intercept the suspended coating material, reducing the amount of suspended coating material entering the feeding area and the discharging area.

[0024] Adsorption plates 14 are provided on both sides of the bottom center of the spraying chamber. The top of the moving end is located between the two adsorption plates 14. The tops of both ends of the adsorption plates 14 are connected to the bottom of the baffle 3. The distance between the two adsorption plates 14 is not less than the width of the gap groove. The size of the adsorption plates 14 and the distance between the two adsorption plates 14 can be set according to the requirements and are not limited here. Both the baffle 3 and the adsorption plates 14 are hollow structures. Suction holes are provided on the outer side of the baffle 3 and the inner side of the adsorption plates 14. The inner cavity of the baffle 3 and the inner cavity of the adsorption plates 14 are connected through the connecting pipe 6.

[0028] In summary: When using this aluminum profile surface spraying device, the moving component drives the aluminum profile to move within the spraying chamber. When the aluminum profile moves to the spraying area, the spraying component 16 sprays the surface of the aluminum profile. The suspended coating generated during the spraying process can enter the feeding area, the discharging area, and the inner cavity of the slot 12. The exhaust fan 1 9 and exhaust fan 2 7 work. The operation of exhaust fan 1 9 causes the air around the baffle 3 to enter the coating along the baffle 3, connecting pipe 1 6, connecting pipe 2 10, and connecting pipe 3 15. Inside the recycling bin 11, the operation of the exhaust fan 7 causes the air containing suspended paint in the spraying area to enter the paint recycling bin 11 through the air inlet pipe 8 and the air outlet pipe. The suspended paint in the air is recycled in the paint recycling bin 11. During this process, outside air enters the spraying area through the slot 12, the air inlet area and the air outlet area, reducing the amount of suspended paint in the spraying area, facilitating paint recycling, and preventing paint from adhering to unsprayed or sprayed aluminum profiles and moving components, thus ensuring the quality of aluminum profile spraying.
