[0024] Reference Figures 1-3 An embodiment of this utility model provides a double-cylinder rotary coating device, including a base plate 1, a hydraulic cylinder 2 fixedly connected to the upper surface of the base plate 1, a transmission gear plate 3 fixedly connected to the output end of the hydraulic cylinder 2, a first gear 4 meshing with the outer wall of the transmission gear plate 3, a lower surface of the transmission gear plate 3 slidably connected to the upper surface of the base plate 1, a transmission shaft 5 fixedly connected to the inner wall of the first gear 4, a second gear 6 fixedly connected to the outer wall of the transmission shaft 5, a support plate 11 rotatably connected to the outer wall of the transmission shaft 5, a gear column 7 meshing with the outer wall of the second gear 6, a support column 8 slidably connected to the outer wall of the gear column 7, a bottom column 10 fixedly connected to the upper surface of the base plate 1, a sliding column 9 slidably connected to the inner wall of the bottom column 10, a condensate tank 12 provided on the upper surface of the gear column 7, and a fixing component provided on the outer wall of the condensate tank 12 for fixing the chassis 15;
[0025] Specifically, hydraulic cylinder 2 is activated, which drives the transmission gear plate 3 to move. The movement of the transmission gear plate 3 drives the first gear 4 to rotate. The rotation of the first gear 4 drives the transmission shaft 5 to rotate. The rotation of the transmission shaft 5 drives the second gear 6 to rotate. The rotation of the second gear 6 drives the gear column 7 to move up and down, thereby achieving the effect of adjusting the height of the coating equipment.
[0026] Reference Figure 3 and Figure 4 The fixed assembly includes a water pipe 13, the outer wall of which is fixedly connected to the outer wall of the condensate tank 12. A connecting post 14 is fixedly connected to the outer wall of the condensate tank 12. A chassis 15 is fixedly connected to the outer wall of the connecting post 14. A rotating disk 16 is rotatably connected to the outer wall of the chassis 15. A fixing post 17 is fixedly connected to the outer wall of the rotating disk 16. A connecting cap 18 is fixedly connected to the outer wall of the fixing post 17. A rotating arm 19 is rotatably connected to the inner wall of the rotating disk 16. A fan blade 20 is rotatably connected to the outer wall of the rotating arm 19.
[0027] Specifically, rotating the connecting cap 18 drives the fixed column 17 to rotate, which in turn drives the rotating disk 16 to rotate, which in turn drives the rotating arm 19 to rotate, which in turn drives the fan blade 20 to rotate, thereby quickly adding cooling water to the condensate tank 12 to reduce the temperature generated during equipment operation.
[0028] Reference Figure 1 and Figure 4 The outer wall of the fan blade 20 is rotatably connected to the outer wall of the chassis 15; the lower surface of the support plate 11 is fixedly connected to the upper surface of the base plate 1; the lower surface of the support column 8 is fixedly connected to the upper surface of the base plate 1.
[0029] Specifically, the fan blade 20 rotates on the outer wall of the chassis 15, and the support plate 11 is used to support the drive shaft 5 to rotate.
[0030] Working principle: When this double-cylinder rotary coating equipment is needed, firstly, the hydraulic cylinder 2 is started. The hydraulic cylinder 2 will drive the transmission gear plate 3 at its output end to move. When the transmission gear plate 3 moves, it will drive the first gear 4 on its outer wall to rotate. When the first gear 4 rotates, it will drive the transmission shaft 5 on its inner wall to rotate. When the transmission shaft 5 rotates, it will drive the second gear 6 on its outer wall to rotate. When the second gear 6 rotates, it will drive the toothed column 7 on its outer wall to slide up and down on the inner wall of the support column 8, thereby achieving the effect of adjusting the coating equipment to a suitable height. Rotating the connecting cap 18 will drive the fixing column 1 on its outer wall to rotate. When the fixed column 17 rotates, it drives the rotating disk 16 on its outer wall to rotate. When the rotating disk 16 rotates, it drives the rotating arm 19 on its inner wall to rotate. When the rotating arm 19 rotates, it drives the fan blade 20 on its outer wall to rotate, thereby quickly adding cooling water to the condensate tank 12, reducing the heat generated during equipment operation, and extending the service life of the equipment. Finally, this double-cylinder rotary coating equipment can not only adjust the equipment to a suitable height by moving the toothed column 7 up and down, but also add cooling water to the condensate tank 12 through the fan blade 20, preventing the equipment's service life from being reduced due to excessive temperature.
