The inner wall of the conveyor belt 2 is rotatably connected to two rotating rollers 15. Both ends of each rotating roller 15 are rotatably connected to the inner side wall of the conveyor frame 1. The rotating rollers 15 can drive the conveyor belt 2 to rotate, which makes it convenient to drive the conveyor belt 2 to transport sheet metal and increases the convenience of sheet metal transportation.
[0025] Each multi-port pipe 7 has several air blowing heads 8 fixedly connected to its outer surface. Two processing boxes 9 are fixedly installed on the upper surface of the support frame 3. Activated carbon plates 10 are slidably connected to the inner wall of each processing box 9. The input end of each air pump 4 passes through the processing box 9 and extends into its interior. A stepper motor 16 is fixedly installed on the left side of the conveyor frame 1. The power output end of the stepper motor 16 passes through the conveyor frame 1 and is fixedly connected to the left end of one of the rotating rollers 15. The stepper motor 16 can provide power for the rotation of the rotating roller 15, thus facilitating the rotation of the rotating roller 15 to drive the conveyor belt 2 to rotate, further increasing the convenience of sheet metal conveying.
[0026] Each processing box 9 has a fixedly connected conveying pipe 11 on its front. Each conveying pipe 11 has three fixedly connected suction hoods 12 on its outer surface. The outer surface of each suction hood 12 is fixedly connected to the outer surface of the support frame 3. Two liquid storage tanks 17 are fixedly installed on the upper surface of the support frame 3. One liquid storage tank 17 stores primer, and the other liquid storage tank 17 stores topcoat. Two liquid pumps 18 are fixedly installed on the upper surface of the support frame 3.

[0030] The working principle of this utility model is as follows: In use, first connect the air pump 4, heating element 6, stepper motor 16, and electric telescopic rod 21 to the power supply. When it is necessary to coat the sheet metal surface, manually place the sheet metal on the conveyor belt 2. The stepper motor 16 drives the rotating roller 15 to rotate, which in turn drives the conveyor belt 2 to transport the sheet metal. The liquid pump 18 draws the primer out of the storage tank 17, allowing it to be delivered to the spray head 20 through the infusion hose 19. The spray head 20 sprays the primer onto the sheet metal surface. The conveyor belt 2 continues to move the sheet metal after the primer has been sprayed. The suction force provided by the air pump 4 draws air from the processing tank 9 into the heating tank 5. The heat provided by the heating element 6 heats the incoming air. The heated air is guided by the multi-port pipe 7 and directly delivered to the blowing head 8. The blowing head 8 blows the heated air onto the sheet metal surface. This allows for the drying of the painted sheet metal. After the air pump 4 extracts the air from the inside of the treatment box 9, a negative pressure is generated inside the treatment box 9, which allows the suction hood 12 to absorb the harmful gases generated during the drying of the sheet metal coating. The harmful gases are then guided directly to the treatment box 9 through the delivery pipe 11. The activated carbon plate 10 can treat the harmful gases, thus facilitating the rapid drying of the painted sheet metal during coating. This improves the drying efficiency of the painted sheet metal and also treats the harmful gases generated during drying. After the primer dries, the sheet metal continues to move. The liquid pump 18 can extract the topcoat stored in another liquid tank 17, allowing the primer to be delivered to the spray head 20 through the liquid delivery hose 19. The spray head 20 can spray the primer onto the sheet metal surface, thus enabling multi-layer coating of the sheet metal and making the multi-layer protective sheet metal surface coating device more practical.
