[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: As shown in Figures 1-4, this utility model provides a technical solution for a metal product surface spraying equipment, including a spraying box 1, a door installed on the front side of the spraying box 1, a discharge pipe 100 installed on one side of the spraying box 1, a fixed structure inside the spraying box 1, a frame 4 inside the spraying box 1, a pushing structure on the outside of the frame 4, two worm gears 10 on one side of the frame 4, and a rotating rod 101 on one side of the frame 4. Both worm gears 10 are fixedly connected to the outside of the rotating rod 101, and support blocks 11 are rotatably connected to both ends of the outside of the rotating rod 101. Both support blocks 11 are fixedly connected to the frame 4. A handle is installed at the bottom of the rotating rod 101. Worm gears 9 are meshed with the outer sides of both worm gears 10. Hollow tubes 7 are fixedly connected to the rear side of the worm gears 9. L-shaped seats 8 are rotatably connected to both ends of the outer side of the hollow tubes 7. Both L-shaped seats 8 are fixedly connected to the frame 4. Multiple nozzles 13 are provided on the outer side of the hollow tubes 7. The multiple nozzles 13 have different lengths. Multiple nozzles 130 are installed on the multiple nozzles 13. A connecting structure is provided between the nozzles 13 and the hollow tubes 7. A material conveying structure is provided between the two hollow tubes 7.

[0023] The connection structure includes a connecting plate 12 and a connecting pipe 14. The connecting plate 12 is disposed between the nozzle 13 and the hollow pipe 7. Both ends of the connecting plate 12 are fixedly connected to the hollow pipe 7 and the nozzle 13, respectively. The connecting pipe 14 is disposed between the nozzle 13 and the hollow pipe 7. Both ends of the connecting pipe 14 are fixedly connected to the nozzle 13 and the hollow pipe 7, respectively. A valve 15 is installed on the outside of the connecting pipe 14.

[0024] The material conveying structure includes a U-shaped tube 700, which is fixedly connected between two hollow tubes 7. A sliding tube 701 is fixedly connected to the outside of the U-shaped tube 700. One end of the sliding tube 701 passes through the inside of the spray box 1 and is slidably connected to the spray box 1. A flexible hose 702 is installed at one end of the sliding tube 701.

[0025] Specifically, turning the throttle causes the lever 101 to rotate the two worm gears 10. The two worm gears 10 mesh with the two worm wheels 9 respectively. Since the threads on the two worm gears 10 are opposite, they mesh with the two worm wheels 9 respectively, causing the two worm wheels 9 to drive the two hollow tubes 7 to rotate in opposite directions. The two hollow tubes 7 drive multiple nozzles 13 to rotate, thus allowing two nozzles 13 of the same length to be switched. This allows for the selection of two suitable nozzles 13 for metal plates of various lengths. After opening two valves 15, paint can be sprayed from the nozzles 130 on the selected two nozzles 13, painting both sides of the metal plate. This improves the practicality of the device and avoids paint waste.

[0026] Connect the hose 702 to the feeding equipment. The coating enters the two hollow tubes 7 through the hose 702, the sliding tube 701 and the U-shaped tube 700. Then, it can enter the two selected spray pipes 13 through the two valves 15, so that the material can be sprayed out through multiple nozzles 130.

[0027] Example: As shown in Figures 1-2, the fixing structure includes two clamping plates 2, both of which are set inside the spray box 1. Rubber anti-slip pads are installed on opposite sides of the two clamping plates 2. Two hydraulic rods 3 are fixedly connected to the outside of the clamping plates 2. Both hydraulic rods 3 pass through the inside of the spray box 1 and are fixedly connected to the spray box 1.

[0028] Specifically, multiple hydraulic rods 3 are activated, and each hydraulic rod 3 drives two clamping plates 2 to move in opposite directions, thereby fixing the metal plate. The two rubber anti-slip pads improve the stability of fixing the metal plate.

[0029] Example: As shown in Figures 1-2, the pushing structure includes two hydraulic rods 5 and four sliding columns 6. The two hydraulic rods 5 are fixedly connected to one side of the frame 4. One end of each hydraulic rod 5 passes through the inside of the spray box 1 and is fixedly connected to the spray box 1. The four sliding columns 6 are all located inside the spray box 1. One end of each sliding column 6 passes through the frame 4 and is slidably connected to the frame 4. Both ends of each sliding column 6 are fixedly connected to the spray box 1.

[0030] Specifically, the two hydraulic rods 25 are activated, which push the frame 4 to move. The frame 4 slides on multiple sliding columns 6, thus enabling the two hollow tubes 7 to move left and right. The surface of the metal sheet can be sprayed through multiple nozzles 13.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
