The other end of the paint channel penetrates through the inner wall of the U-shaped positioning frame and is provided with a paint spraying head. Suction seats are provided in the middle of the inner walls on both sides of the U-shaped positioning frame. A positioning groove is provided on the suction seat, and a telescopic shaft is movably embedded in the positioning groove. The sliding automatic painting device effectively improves the convenience of the painting work.

One end of the first lead screw 4 is welded with a first knob 5. Two groups of sliders 6 are symmetrically assembled in the chute 3. An installation frame 7 is installed on the slider 6. A rotating plate 8 is rotatably installed on the installation frame 7. A steel structure 26 is clamped between the two rotating plates 8. A clamping block 9 is installed on the rotating plate 8. A rotating rod 10 is rotatably installed on one of the installation frames 7. The rotating rod 10 is fixedly connected to the rotating plate 8. A worm gear 11 is fixedly sleeved on the rotating rod 10. Two fixed blocks 12 are fixedly installed on the installation frame 7. A worm 13 is rotatably installed on the fixed block 12. The worm 13 meshes with the worm gear 11. One end of the worm 13 is welded with a second knob 14; during operation, in the process of painting the steel structure 26 with the existing painting device, when turning over the steel structure 26, it is necessary to disassemble and adjust the direction, resulting in poor convenience for turning over. By placing the steel structure 26 between the two rotating plates 8, turning the first knob 5 drives the first lead screw 4 to rotate. The first lead screw 4 drives the two groups of sliders 6 on it to move relatively synchronously. The two groups of sliders 6 drive the two groups of installation frames 7 to move relatively synchronously. The two groups of installation frames 7 drive the two groups of rotating plates 8 to move relatively synchronously, so that the two rotating plates 8 clamp and fix both sides of the steel structure 26; then the nozzle 21 moves horizontally along the axis of the steel structure 26, and the nozzle 21 quickly sprays paint on one side of the steel structure 26. After that, it is necessary to turn over the steel structure 26. By turning the second knob 14, the worm 13 is driven to rotate. The worm 13 pushes the worm gear 11 on it to rotate. The structure of the worm 13 and the worm gear 11 has self-locking property. The worm gear 11 drives the rotating rod 10 to rotate. The rotating rod 10 drives the rotating plate 8 to rotate. The rotating plate 8 drives the clamped steel structure 26 to rotate, realizing the direction adjustment of the steel structure 26 and turning over the steel structure 26, which is beneficial to improving the convenience of turning over.

[0020] Please refer to Figures 4-5As shown, a moving groove 15 is formed in the base 2. A second lead screw 16 is rotatably installed on the inner wall of the moving groove 15. A stepping motor 17 is installed on the side wall of the base 2 through a machine base. The output shaft of the stepping motor 17 is connected to one end of the second lead screw 16. A moving block 18 is assembled in the moving groove 15. A moving frame 19 is installed on the moving block 18. A material plate 20 is installed on the moving frame 19. Multiple groups of nozzles 21 are installed on the material plate 20. A storage tank 22 is installed on the support frame 1 through a fixing plate. The storage tank 22 is connected to a water pump 23 through a conduit. The water pump 23 is connected to the material plate 20 through a conduit. The base 2 is provided with a discharge port. A hopper 24 is installed at the discharge port of the base 2. The discharge end of the hopper 24 is connected to the storage tank 22. A filter plate 25 is fixedly installed on the inner wall of the hopper 24; during operation, the existing painting device cannot recycle the paint, resulting in a low paint recovery rate and serious paint waste. The two rotating plates 8 are used to clamp and fix both sides of the steel structure 26. Then, the stepping motor 17 operates, driving the second lead screw 16 to rotate. The second lead screw 16 drives the moving block 18 thereon to move horizontally. The moving block 18 drives the moving frame 19 to move horizontally. The moving frame 19 drives the material plate 20 to move horizontally. The material plate 20 drives the nozzles 21 to move horizontally. At the same time, the water pump 23 operates. The water pump 23 guides the paint in the storage tank 22 into the material plate 20 and then sprays it out from the nozzles 21. The nozzles 21 move uniformly along the axial direction of the steel structure 26 to spray one side of the steel structure 26 comprehensively; the excess paint drips into the hopper 24. The hopper 24 and the filter plate 25 are made of high-density polyethylene plastic. The surface of the high-density polyethylene plastic plate is smooth and flat and is not easily adhered to the paint. After the excess paint drips into the hopper 24, it is filtered by the filter plate 25, and the pure paint flows back into the storage tank 22, realizing the recycling of the paint and being beneficial to improving the paint recovery rate.

[0021] Working principle: During the painting process of the steel structure 26 by the existing painting device, when turning over the steel structure 26, it is necessary to disassemble and adjust the direction, resulting in poor convenience of turning over. By placing the steel structure 26 between two rotating plates 8, turning the first knob 5 drives the first lead screw 4 to rotate. The first lead screw 4 drives two sliders 6 thereon to move synchronously relative to each other. The two sliders 6 drive two mounting brackets 7 to move synchronously relative to each other. The two mounting brackets 7 drive two rotating plates 8 to move synchronously relative to each other, so that the two rotating plates 8 clamp and fix both sides of the steel structure 26; then the nozzle 21 moves horizontally along the axial direction of the steel structure 26, and the nozzle 21 quickly sprays one side of the steel structure 26. After that, when it is necessary to turn over the steel structure 26, by turning the second knob 14, the worm 13 is driven to rotate. The worm 13 pushes the worm gear 11 thereon to rotate. The structure of the worm 13 and the worm gear 11 has self-locking property. The worm gear 11 drives the rotating rod 10 to rotate. The rotating rod 10 drives the rotating plate 8 to rotate. The rotating plate 8 drives the clamped steel structure 26 to rotate, realizing the direction adjustment of the steel structure 26 and turning over the steel structure 26, which is beneficial to improving the convenience of turning over; the existing painting device cannot recycle the paint, resulting in a low paint recovery rate and serious paint waste. By clamping and fixing both sides of the steel structure 26 with two rotating plates 8, then the stepping motor 17 operates to drive the second lead screw 16 to rotate. The second lead screw 16 drives the moving block 18 thereon to move horizontally. The moving block 18 drives the moving frame 19 to move horizontally. The moving frame 19 drives the material plate 20 to move horizontally. The material plate 20 drives the nozzle 21 to move horizontally. At the same time, the water pump 23 operates. The water pump 23 guides the paint in the storage tank 22 into the material plate 20 and then sprays it out from the nozzle 21. The nozzle 21 moves uniformly along the axial direction of the steel structure 26 to spray the whole side of the steel structure 26; the excess paint drips into the hopper 24. The hopper 24 and the filter plate 25 are made of high-density polyethylene plastic. The surface of the high-density polyethylene plastic plate is smooth and flat and not easy to adhere to the paint. After the excess paint drips into the hopper 24, it is filtered by the filter plate 25, and the pure paint flows back into the storage tank 22, realizing the recycling of the paint and being beneficial to improving the paint recovery rate.
