[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-7 A PVC film coating machine includes a coating box 1, a U-shaped support 2 at one end of the coating box 1, a rotatable film feeding roller 3 at the bottom inside the U-shaped support 2, a rotatable film taking roller 4 at the top inside the U-shaped support 2, and a first drive motor 5 bolted to the top and bottom of one side of the U-shaped support 2. The output end of one of the first drive motors 5 is fixedly connected to the film feeding roller 3, and the output end of the other first drive motor 5 is fixedly connected to the film taking roller 4.

[0033] The top and bottom of one end of the coating box 1 are rotatably connected to a first driven roller 11, and the inside of the other end of the coating box 1 is rotatably connected to a second driven roller 12. A PVC film is sleeved on the outside of the second driven roller 12. One end of the PVC film is connected to the unwinding roller 3, and the other end of the PVC film is connected to the rewinding roller 4. The PVC film passes between the two first driven rollers 11. Through the operation of the first drive motor 5, the unwinding roller 3 can unwind, and the rewinding roller 4 can rewind. The PVC film can pass between the two first driven rollers 11 and is located outside the second driven roller 12.

[0034] The coating box 1 is equipped with a cleaning component for cleaning PVC film. The coating box 1 is also equipped with two coating mechanisms for coating PVC film. One coating mechanism is located on the top of the PVC film outside the bottom of the second driven roller 12, and the other coating mechanism is located on the top of the PVC film outside the top of the second driven roller 12, so that the two coating mechanisms can spray both sides of the PVC film.

[0035] The cleaning assembly includes a rectangular cleaning box 7, which is fixed inside the coating box 1. Rotatable longitudinal cleaning rollers 6 are provided at the top and bottom of one end of the rectangular cleaning box 7. An adjustment mechanism for adjusting the distance between the two longitudinal cleaning rollers 6 is provided on one side of the rectangular cleaning box 7. A U-shaped dust collection box 13 is also provided at the other end of the rectangular cleaning box 7. A blower 10 is bolted to the other side of the rectangular cleaning box 7. The input end of the blower 10 is connected to the U-shaped dust collection box 13. Through the operation of the blower 10, the U-shaped dust collection box 13 can collect dust and discharge it to the outside, so as to facilitate the collection of dust on the surface of the PVC film, ensure that the cleaning force is moderate, avoid damage to the film material, and can quickly and accurately adapt to PVC films of different thicknesses.

[0036] The adjustment mechanism includes a transverse hydraulic cylinder 17. A transverse hydraulic cylinder 17 is fixed on one side of a rectangular cleaning box 7. A transverse sliding plate 18 is fixed to the output end of the transverse hydraulic cylinder 17. A transverse rotating column 19 is rotatably connected to the top and bottom of the transverse sliding plate 18 via a pin. A U-shaped sliding seat 16 is rotatably connected to the end of the transverse rotating column 19 away from the transverse sliding plate 18 via a pin. A second drive motor 8 is bolted to one side of the U-shaped sliding seat 16. The output end of the second drive motor 8 is fixedly connected to the longitudinal cleaning roller 6.

[0037] The rectangular cleaning box 7 has a vertical groove inside. The U-shaped sliding seat 16 is located inside the vertical groove and is slidably connected to the rectangular cleaning box 7 through the vertical groove. The vertical groove allows the U-shaped sliding seat 16 to slide vertically inside the rectangular cleaning box 7, thereby allowing the distance between the two U-shaped sliding seats 16 to be adjusted.

[0038] Here, the operation of the first drive motor 5 enables the longitudinal cleaning roller 6 to rotate, allowing the longitudinal cleaning roller 6 to clean the dust on the surface of the PVC film. The operation of the blower 10 enables the U-shaped dust collection box 13 to collect the dust on the surface of the PVC film. When the thickness of the PVC film changes, the operation of the transverse hydraulic cylinder 17 enables the transverse sliding plate 18 to move. The movement of the transverse sliding plate 18 causes the U-shaped sliding seat 16 to slide vertically inside the rectangular cleaning box 7, thereby allowing the distance between the two longitudinal cleaning rollers 6 to be adjusted, so that the two longitudinal cleaning rollers 6 can adapt to PVC films of different thicknesses.

[0039] The coating mechanism includes a vertical hydraulic cylinder 9, a vertical rectangular frame 20 fixed to the output end of the vertical hydraulic cylinder 9, a longitudinal spray pipe 21 fixed inside the U-shaped support 2, a vertical lifting plate 22 fixed to one side of the vertical rectangular frame 20, and the longitudinal spray pipe 21 located at the bottom of the vertical lifting plate 22. The two ends of the vertical lifting plate 22 are rotatably connected to the inclined partition 15 by a pin, and the bottom of the inclined partition 15 is rotatably connected to the vertical partition plate 14 by a pin. U-shaped support frames 23 are provided on both sides between the two vertical partition plates 14, and the U-shaped support frames 23 are fixedly connected to the coating box 1.

[0040] The coating box 1 has a vertical through slot inside. The vertical rectangular frame 20 is located inside the vertical through slot and is slidably connected to the coating box 1 through the vertical through slot. The vertical through slot allows the vertical rectangular frame 20 to be vertically raised and lowered inside the coating box 1, thereby allowing the longitudinal spray pipe 21 and the vertical lifting plate 22 to be vertically raised and lowered.

[0041] The vertical partition plate 14 has a horizontal through groove inside. The U-shaped support frame 23 is located inside the horizontal through groove and is slidably connected to the vertical partition plate 14 through the horizontal through groove. The horizontal through groove allows the vertical partition plate 14 to slide on the outside of the U-shaped support frame 23, thereby allowing the distance between the two vertical partition plates 14 to be adjusted.

[0042] Here, the operation of the vertical hydraulic cylinder 9 enables the vertical rectangular frame 20 to be vertically raised and lowered inside the coating box 1. The raising and lowering of the vertical rectangular frame 20 enables the vertical lifting plate 22 and the longitudinal spray pipe 21 to be vertically raised and lowered. The raising and lowering of the vertical lifting plate 22 enables the vertical partition plate 14 to slide laterally on the outside of the U-shaped support frame 23 via the inclined partition 15, thereby adjusting the distance between the two vertical partition plates 14. The setting of the inclined partition plate 15 and the vertical partition plate 14 can effectively prevent liquid splashing, improve the spraying accuracy and coating uniformity, reduce the waste of coating materials, and reduce production costs.

[0043] In use: the operation of the first drive motor 5 enables the longitudinal cleaning roller 6 to rotate, so that the longitudinal cleaning roller 6 can clean the dust on the surface of the PVC film. The operation of the blower 10 enables the U-shaped dust collection box 13 to collect the dust on the surface of the PVC film. When the thickness of the PVC film changes, the operation of the transverse hydraulic cylinder 17 enables the transverse sliding plate 18 to move. The movement of the transverse sliding plate 18 enables the U-shaped sliding seat 16 to slide vertically inside the rectangular cleaning box 7, thereby allowing the distance between the two longitudinal cleaning rollers 6 to be adjusted, so that the two longitudinal cleaning rollers 6 can adapt to PVC films of different thicknesses.

[0044] The operation of the vertical hydraulic cylinder 9 enables the vertical rectangular frame 20 to be vertically raised and lowered inside the coating box 1. The raising and lowering of the vertical rectangular frame 20 enables the vertical lifting plate 22 and the longitudinal spray pipe 21 to be vertically raised and lowered. The raising and lowering of the vertical lifting plate 22 enables the vertical partition plate 14 to slide laterally on the outside of the U-shaped support frame 23 via the inclined partition 15, thereby adjusting the distance between the two vertical partition plates 14. The setting of the inclined partition plate 15 and the vertical partition plate 14 can effectively prevent liquid splashing, improve the spraying accuracy and coating uniformity, reduce the waste of coating materials, and reduce production costs.

[0045] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
