Description

Technical Field

[0001] The present application relates to the field of film coating technology, and in particular to a film coating device for a surface. Background Art

[0002] Coating the surface of a sheet is a surface treatment method that achieves different functions or meets specific requirements by covering the surface of the sheet with a film or coating. This treatment is usually used to protect the surface of the sheet, beautify the appearance, increase wear resistance, corrosion resistance or improve specific physical properties.

[0003] At present, in the process of laminating the surface of the board, since the edges of the board may not be properly cut or trimmed, the adhesion effect of the film at the edges will be affected, and bubbles and wrinkles will be easily generated at the edges of the lamination. Loose lamination can easily lead to loose contact between the film and the surface of the board, reducing the protective performance of the film. Utility Model Content

[0006] Preferably, the edge pressing mechanism includes a bracket fixedly connected to the inner side of the device frame, and an electric push rod is fixedly installed on the bracket. The edge pressing mechanism can further pressurize and hold the film attached to the edge of the plate, thereby improving the connection stability and tightness of the coating.

[0007] Preferably, the output end of the electric push rod is fixedly connected with a concave plate, and a damping shaft is fixedly penetrated through the inner side of the concave plate. The design of the damping shaft here can adapt to coated plates with different slopes.

[0009] Preferably, inner shafts are fixedly provided at both ends of the platform, and rollers are rotatably connected to the outer surfaces of the inner shafts.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The film laminating device for the surface can make the roller roll along the edge of the film laminating plate through the edge pressing mechanism, so that the film is more closely attached to the surface of the plate, improving the stability of the attachment, and at the same time providing continuous pressure and friction, which helps to ensure the close contact between the film and the plate. This continuous pressure helps to exclude air and any gaps that may cause bubbling or loosening of the film.

[0012] 2. The surface coating device can adjust the position of the roller according to the coated panels of different heights and surface inclinations through the design of the electric push rod and the damping shaft, ensuring that the rollers at both ends of the platform can be stably pressed against the surface of the panel with appropriate force, which can adapt to a wider range of application scenarios.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1-3A coating device for a surface comprises a device frame 1, a conveying platform 2 is fixedly installed inside the device frame 1, a coating plate 3 is transported on the conveying platform 2, a fixed cylinder 4 is fixedly connected to the inner side of the device frame 1, a slide rod 5 is slidably sleeved on the inner surface of the fixed cylinder 4, a spring 6 is movably sleeved on the outer surface of the slide rod 5, and the top of the spring 6 is fixedly connected to the bottom of the fixed cylinder 4, a base 7 is fixedly connected to the bottom of the slide rod 5, a seat shaft 8 is fixedly penetrated on the inner side of the base 7, a coating roller 9 is rotatably connected to the outer surface of the seat shaft 8, and an edge pressing mechanism is arranged on the device frame 1.

[0019] Through the above technical solution, when the device is in use, the plate is transported on the conveyor table 2. During this process, the coating roller 9 will be pressed against the surface of the plate with appropriate force under the action of the spring 6. Along with the transportation of the coated plate 3 by the conveyor table 2 and the rolling of the coating roller 9, the film can be attached to the plate. Then, the edge pressing mechanism can allow the roller 17 to continuously roll and press along the edge of the coated plate 3, thereby improving the tightness and stability of the film during the attachment process.

[0020] Specifically, the edge pressing mechanism includes a bracket 10 fixedly connected to the inner side of the device frame 1 , and an electric push rod 11 is fixedly mounted on the bracket 10 .

[0021] Through the above technical solution, the electric push rod 11 can push the roller 17 forward to a suitable height to adapt to the film-coated plates 3 of different heights.

[0022] Specifically, the output end of the electric push rod 11 is fixedly connected with a concave plate 12 , and a damping shaft 13 is fixedly penetrated through the inner side of the concave plate 12 .

[0023] Through the above technical solution, since the damping shaft 13 has damping characteristics, the connecting frame 14 will remain in a relatively stable state after rotating to a suitable position along the damping shaft 13, which is to fine-tune the inclination angle of the platform 15 to adapt to the coated board 3 with different surface slopes.

[0024] Specifically, the outer surface of the damping shaft 13 is rotatably connected with a connecting frame 14 , the bottom of the connecting frame 14 is fixedly connected with a platform 15 , and there are two groups of platforms 15 .

[0025] Through the above technical solution, rollers 17 are provided at the ends of the two sets of platforms 15, which are used to perform secondary lamination treatment on the film-coated plate material 3.

[0026] Specifically, inner shafts 16 are fixedly provided at both ends of the platform 15 , and rollers 17 are rotatably connected to the outer surface of the inner shaft 16 .

[0027] Through the above technical solution, when the roller 17 rolls against the film on the surface of the film-coated plate 3 , it will rotate along the inner shaft 16 .

[0028] Working principle: When the device is in use, the coated sheet material 3 is transported on the conveying platform 2. Under the action of the spring 6, the slide bar 5 can slide along the inside of the fixed cylinder 4 and drive the base 7 to make the coating roller 9 press against the coated sheet material 3 with appropriate force. During the rotation of the coating roller 9 along the seat shaft 8, the film can be unfolded and attached to the coated sheet material 3. While the sheet material is coated, the electric push rod 11 can be turned on to push the connecting frame 14 to tilt and push down until the roller 17 is pressed against the coated sheet material 3 with appropriate force. During this process, the connecting frame 14 can be rotated along the damping shaft 13 until the platform 15 is adjusted to a suitable inclination angle. This process is to allow The rollers 17 at both ends of the platform 15 are pressed against the film-coated sheet material 3 with the same and appropriate force, thereby adapting to the film-coated sheet material 3 with different surface slopes, improving the functionality of the device, and the rollers 17 can increase the adhesion between the film and the sheet material during the continuous rolling along the edge of the film-coated sheet material 3. The rollers 17 continuously apply pressure by rolling, so that the film is more closely attached to the surface of the sheet material, thereby improving the stability of the adhesion, and the continuous rolling of the rollers 17 can provide continuous pressure and friction, which helps to ensure close contact between the film and the sheet material. This continuous pressure helps to eliminate air and any gaps that may cause bubbling or loosening of the film.
