[0026] The other end of the bottom of the U-shaped mounting bracket 1 is fixed with a drying box 4, and the bottom of the L-shaped mounting bracket 2 is equipped with a heating mechanism;

[0027] A film-coating storage box 6 is fixed to one end of the top of the U-shaped mounting bracket 1. A material pump 7 is bolted to the film-coating storage box 6. The input end of the material pump 7 is connected to the film-coating storage box 6, and the output end of the material pump 7 is connected to the rectangular scraper 3. The rectangular scraper 3 has a discharge port inside. Through the operation of the material pump 7, the film-coating liquid inside the film-coating storage box 6 can be injected into the interior of the rectangular scraper 3 and injected into the surface of the printed product through the discharge port.

[0028] The rotating mechanism includes a transverse hydraulic cylinder 9, which is fixed to the outside of the U-shaped mounting bracket 1. The output end of the transverse hydraulic cylinder 9 is rotatably connected to a longitudinal sliding column 10 via a bearing. A transverse transmission column 11 is rotatably connected to the outside of the longitudinal sliding column 10. A transverse rotating column 12 is rotatably connected to one end of the transverse transmission column 11. A longitudinal rotating column 13 is fixed inside the transverse rotating column 12. The longitudinal rotating column 13 passes through the interior of the U-shaped mounting bracket 1 and is rotatably connected to the U-shaped mounting bracket 1 via a bearing. The longitudinal rotating column 13 is located on the side close to the rectangular scraper 3 and is fixedly connected to the rectangular scraper 3.

[0029] A dovetail slider is fixed on the side of the longitudinal sliding column 10 near the U-shaped mounting bracket 1. A dovetail groove is provided inside the U-shaped mounting bracket 1. The longitudinal sliding column 10 and the U-shaped mounting bracket 1 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. By setting the dovetail slider and the dovetail groove, the longitudinal sliding column 10 can move laterally on the outside of the U-shaped mounting bracket 1, and thus can enter the movement trajectory of the longitudinal sliding column 10.

[0030] The bottom of the drying oven 4 is provided with rectangular ventilation holes. A fan 14 is fixed on the outside of the drying oven 4. Multiple first U-shaped heating tubes 15 are evenly distributed inside the drying oven 4. The fan 14 allows outside air to enter the drying oven 4. The operation of the first U-shaped heating tubes 15 heats the air and injects it into the surface of the coated color-printed products through the rectangular ventilation holes, thereby improving the drying efficiency of the color-printed products after touch.

[0031] Here, the operation of the material pump 7 enables the coating liquid inside the coating storage tank 6 to be injected into the rectangular scraper 3 and then injected into the surface of the printed product through the discharge port.

[0032] The operation of the transverse hydraulic cylinder 9 enables the longitudinal sliding column 10 to move laterally on the outside of the U-shaped mounting frame 1. The movement of the longitudinal sliding column 10, through the transverse transmission column 11 and the transverse rotating column 12, enables the longitudinal rotating column 13 to rotate, thereby enabling the longitudinal rotating column 13 to rotate inside the U-shaped mounting frame 1. The rotation of the longitudinal rotating column 13 enables the rectangular scraper 3 to rotate, and the rotation of the longitudinal rotating column 13 enables the coating liquid to be applied evenly and continuously to the surface of the printed product.

[0033] The heating mechanism includes a U-shaped support plate 18, with a drying drum 5 rotatably connected inside the U-shaped support plate 18 via bearings. A rectangular fixing plate 20 is fixed to one end of the top of the U-shaped support plate 18, and a second drive motor 21 is bolted to one end of the rectangular fixing plate 20. The second drive motor 21 is connected to the drying drum 5 via a track. A second U-shaped heating tube 19 is installed inside the drying drum 5, and the other end of the second U-shaped heating tube 19 is fixedly connected to the U-shaped support plate 18. A lifting assembly is installed between the L-shaped mounting bracket 2 and the U-shaped support plate 18. The operation of the second drive motor 21 causes the drying drum 5 to rotate inside the U-shaped support plate 18 via the track, thereby allowing the drying drum 5 to rotate outside the second U-shaped heating tube 19. The operation of the second U-shaped heating tube 19 heats the temperature of the drying drum 5, enabling the drying drum 5 to quickly dry the laminated printed products and prevent the undried film layer from sticking or being damaged in subsequent processes.

[0034] The lifting assembly includes a first drive motor 8, the top of the L-shaped mounting bracket 2 is fixed with the first drive motor 8, the output end of the first drive motor 8 is fixed with a vertical threaded rod 22, the outer side of the vertical threaded rod 22 is threaded with a rectangular lifting frame 17, the bottom of the rectangular lifting frame 17 is fixedly connected with a U-shaped support plate 18, the outer side of the rectangular lifting frame 17 is slidably connected with a rectangular mounting box 16, and the top of the rectangular mounting box 16 is fixedly connected with the L-shaped mounting bracket 2.

[0035] Vertical light rods 23 are provided at both ends inside the rectangular mounting box 16. The top of the vertical light rods 23 is fixedly connected to the L-shaped mounting bracket 2. The vertical light rods 23 penetrate the interior of the rectangular lifting frame 17 and are slidably connected to the rectangular lifting frame 17. By setting the vertical light rods 23, the rectangular lifting frame 17 can slide vertically on the outside of the vertical light rods 23, thereby guiding the vertical lifting trajectory of the rectangular lifting frame 17.

[0036] Here, the operation of the first drive motor 8 enables the vertical threaded rod 22 to rotate. The rotation of the vertical threaded rod 22 enables the rectangular lifting frame 17 to slide vertically inside the rectangular mounting box 16, thereby enabling the U-shaped support plate 18 to rise and fall vertically. This makes the position and height of the drying drum 5 adjustable. The vertical guide rod 23 guides the vertical rising and falling trajectory of the rectangular lifting frame 17, and the position of the drying drum 5 is adjustable, thus allowing adjustment according to the height of different printed products.

[0037] The operation of the second drive motor 21 enables the drying drum 5 to rotate inside the U-shaped support plate 18 via the track, thereby allowing the drying drum 5 to rotate outside the second U-shaped heating tube 19. The operation of the second U-shaped heating tube 19 can heat the temperature of the drying drum 5, enabling the drying drum 5 to quickly dry the coated printed products and prevent the undried film layer from sticking or being damaged in subsequent processes.

[0038] By setting a discharge port inside the rectangular scraper 3 and combining it with a rotating mechanism, the coating liquid can be evenly and continuously applied to the surface of the printed products, avoiding the problems of liquid accumulation or uneven coating that may occur when coating with a traditional coating roller. This significantly improves the flatness and consistency of the coating. The use of a vertically adjustable drying roller 5 allows for flexible adjustment of the heating position according to the thickness of the printed products, enabling the surface of the printed products to dry quickly after coating. This prevents the uncured film layer from sticking or scratching during subsequent winding or stacking, thus improving the production yield.

[0039] Working principle: Through the operation of the material pump 7, the coating liquid inside the coating storage tank 6 can be injected into the rectangular scraper 3 and then injected into the surface of the printed product through the discharge port.

[0040] The operation of the transverse hydraulic cylinder 9 enables the longitudinal sliding column 10 to move laterally on the outside of the U-shaped mounting frame 1. The movement of the longitudinal sliding column 10, through the transverse transmission column 11 and the transverse rotating column 12, enables the longitudinal rotating column 13 to rotate, thereby enabling the longitudinal rotating column 13 to rotate inside the U-shaped mounting frame 1. The rotation of the longitudinal rotating column 13 enables the rectangular scraper 3 to rotate, and the rotation of the longitudinal rotating column 13 enables the coating liquid to be applied evenly and continuously to the surface of the printed product.

[0041] The operation of the first drive motor 8 enables the vertical threaded rod 22 to rotate. The rotation of the vertical threaded rod 22 allows the rectangular lifting frame 17 to slide vertically inside the rectangular mounting box 16, thereby enabling the U-shaped support plate 18 to rise and fall vertically. This makes the position and height of the drying drum 5 adjustable. The vertical guide rod 23 guides the vertical rising and falling trajectory of the rectangular lifting frame 17, and the position of the drying drum 5 is adjustable, thus allowing adjustment according to the height of different printed products.

[0042] The operation of the second drive motor 21 enables the drying drum 5 to rotate inside the U-shaped support plate 18 via the track, thereby allowing the drying drum 5 to rotate outside the second U-shaped heating tube 19. The operation of the second U-shaped heating tube 19 can heat the temperature of the drying drum 5, enabling the drying drum 5 to quickly dry the coated printed products and prevent the undried film layer from sticking or being damaged in subsequent processes.
