Description

Technical Field

[0001] This utility model relates to integrated wall panel production equipment, and more specifically, to a film coating device for integrated wall panels. Background Technology

[0002] Integrated wall panels are a new type of interior decoration material that combines the decorative and protective functions of walls, featuring aesthetics, durability, and easy installation. There are many types of integrated wall panels, including wood-based panels, composite material panels, and polymer-based panels (such as PVC and PET).

[0003] For polymer-based integrated wall panels, the manufacturing process generally includes mixing the polymer and additives, extrusion molding, lamination, and cutting. Common integrated wall panels include flat types and non-flat types with continuous raised square structures. Lamination of flat integrated wall panels is relatively simple; the surface film is simply applied and pressed flat. However, non-flat integrated wall panels with continuous raised square structures require multiple rollers to work together, pressing and bonding the panels section by section. For example... Figure 1 and Figure 2 The image shows a simplified laminating device for a non-planar integrated wall panel (7 consisting of only one continuous raised square). The laminating machine conveys the surface film to the top of the integrated wall panel. First, the surface roller 1 presses the surface film onto the upper surface of the integrated wall panel. Then, the side roller 2 applies the film to the sides of the integrated wall panel. Next, the edge plate roller 3 and end plate roller 4 apply the film to the upper surface and sides of the edge plate 8 of the integrated wall panel. Finally, the edge-trimming roller 5 trims the surface film, ensuring that any excess film adheres to the bottom of the integrated wall panel. Additionally, two inclined rollers 6 are provided at the corners of the edge plate 8 for bending the surface film. It should be noted that the surface roller 1, side roller 2, and edge plate roller 3 form a raised pressing roller group. When there are multiple continuous raised squares on the integrated wall panel, a pressing roller group with the same number of continuous raised squares can be used. Each integrated wall panel has two side panels 8, so each side panel 8 only needs to be equipped with one end face roller 4, one edge finishing roller 5 and two oblique rollers 6.

[0004] Current lamination equipment can adhere the surface film to the surface of integrated wall panels relatively smoothly and firmly. However, for the surface film at the edge, the edge width is small, generally around 1cm (related to cost control), and small protrusions or bumps are prone to appear at the edges of integrated wall panels. If these protrusions are encountered, they will affect the edge finishing effect, causing the surface film at the edge to be unstable or fall off after a short time, affecting product quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a film coating device for integrated wall panels, which improves the film coating effect by smoothing the edge of the integrated wall panel.

[0006] The present invention provides a film coating device for integrated wall panels, comprising a support frame and surface rollers, side rollers, edge plate rollers, end face rollers, edge finishing rollers and inclined rollers rotatably mounted on the support frame. A leveling device is provided between the edge plate rollers and the end face rollers, and the leveling device is fixedly mounted on the support frame.

[0007] The leveling device includes a base and a leveling blade; the base is fixedly mounted on a support frame, the leveling blade is located on one side of the base and faces the extrusion direction of the integrated wall panel; an air inlet is provided below the base, and a cold air chamber and a hot air chamber are opened in the base and connected to the air inlet; a cold air duct is provided on one side of the cold air chamber and faces the leveling blade; a hot air duct is provided above the hot air chamber, and a chip removal channel is provided between the base and the leveling blade, and the hot air duct is connected to the chip removal channel.

[0008] Preferably, an isolation plate is provided between the cold air chamber and the hot air chamber, and the air outlet direction of the air inlet connector faces the isolation plate.

[0009] Preferably, the end of the isolation plate near the air intake connector has a semi-circular shape.

[0010] Preferably, both sides of the chip removal channel are provided with protrusions extending toward the center, and the sidewalls of the protrusions are inclined.

[0014] Beneficial effects

[0015] The advantages of this invention are as follows: A leveling device is installed between the side plate roller and the end face roller. This device levels the edges of the lower surface of the integrated wall panel's side plate, thus avoiding the problem of uneven edges affecting the lamination effect. Furthermore, the leveling device can also provide cold air to blow away the trimmed debris, preventing it from affecting the lamination effect.

Detailed Implementation

[0022] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0023] This utility model discloses a film-coating device for integrated wall panels, comprising a support frame and surface rollers 1, side rollers 2, edge plate rollers 3, end face rollers 4, edge-trimming rollers 5, and inclined rollers 6 rotatably mounted on the support frame. Since this utility model does not improve upon the above rollers, their specific installation and application will not be described in detail here. The following will refer to… Figures 3-5 The coating device of this utility model will be introduced using a simplified model of the integrated wall panel 7.

[0024] A leveling device 10 is provided between the side plate roller 3 and the end face roller 4, and the leveling device 10 is fixedly mounted on the support frame. The leveling device 10 is used to level the edge of the lower surface of the side plate 8 of the integrated wall panel 7, thereby avoiding the problem of uneven edges affecting the lamination effect. In addition, the leveling device 10 in this embodiment can also provide cold air to blow away the trimmed debris, preventing the debris from affecting the lamination effect. Furthermore, the leveling device 10 can also provide hot air, which can further blow away debris and dust at the edge position, and can also heat the area to be laminated, which is beneficial for subsequent lamination, thereby greatly improving the lamination effect. In this embodiment, the leveling device 10 is installed between the side plate roller 3 and the end face roller 4. From the rolling direction, the surface film in front of the leveling device 10 (i.e. the side of the integrated wall panel that has not been leveled) is only in contact with the side plate 8, and the edge of the surface film is in a position parallel to the upper surface of the side plate 8. At this time, the lower surface of the side plate 8 is leveled, dust is removed, and then the side of the side plate 8 is attached and the edge is finished. This can prevent debris from adhering to the surface film and causing poor film coating effect.

[0025] The leveling device 10 includes a base 11 and a leveling blade 12. The base 11 and the leveling blade 12 are an integral structure, improving the overall strength of the leveling device. The base 11 is fixedly mounted on a support frame, and the leveling blade 12 is located on one side of the base 11, facing the extrusion direction of the integrated wall panel 7. An air inlet 16 is located below the base 11, connecting to an external air source. The base 11 has a cold air chamber 14 and a hot air chamber 13 connected to the air inlet 16. A cold air duct 19 is located on one side of the cold air chamber 14, facing the leveling blade 12, used to blow away the trimmed debris. A hot air duct 18 is located above the hot air chamber 13, and a chip removal channel 20 is located between the base 11 and the leveling blade 12. The hot air duct 18 is connected to the chip removal channel 20, used to further blow away debris and dust at the edges, while simultaneously heating the area to be coated.

[0026] In this embodiment, an isolation plate 15 is provided between the cold air chamber 14 and the hot air chamber 13, and the air outlet direction of the air inlet 16 faces the isolation plate 15. That is, the cavity inside the seat 11 is separated by the isolation plate 15 to form two air chambers. This design eliminates the need for an additional air inlet to supply both hot and cold air. The hot air chamber 13 is equipped with an electric heater 17 to heat the gas inside, forming hot air, while the cold air chamber 14 directly blows out the gas supplied from the air inlet 16. To reduce interference between the two air chambers, the inner walls of both chambers are lined with an insulation layer, and the isolation plate 15 is made of a material with poor thermal conductivity, such as insulation cotton or ceramic.

[0027] Preferably, the end of the baffle plate 15 near the air inlet connector 16 has a semi-circular shape, so that the end face of the baffle plate 15 forms an air guiding surface and reduces wind resistance.

[0028] In this embodiment, both sides of the chip removal channel 20 are provided with protrusions 21 extending toward the center, and the sidewalls of the protrusions 21 are inclined. That is, when viewed from above, the protrusions 21 have a V-shaped structure, which is conducive to the discharge of hot air and at the same time avoids the accumulation of debris and dust on the wall surface of the chip removal channel.

[0029] In this embodiment, a hot-pressing roller 9 is provided between the end-face roller 4 and the edge-trimming roller 5. The edge-trimming process, consisting of the hot-pressing roller 9 and the edge-trimming roller 5, enhances the adhesion of the surface film through hot pressing. Furthermore, the secondary rolling action of the edge-trimming roller 5 significantly improves the adhesion effect of the surface film. The hot-pressing roller 9 and the edge-trimming roller 5 have the same external structure; the difference lies in the fact that the hot-pressing roller contains a heating wire, which heats the surface film, thereby achieving hot pressing.

[0030] The working principle of this utility model is as follows: The laminating machine conveys the surface film to the integrated wall panel 7. First, the surface roller 1 presses the surface film onto the upper surface of the integrated wall panel 7. Then, the side roller 2 applies the film to the sides of the integrated wall panel 7. Next, the edge plate roller 3 applies the film to the upper surface of the edge plate 8. After the integrated wall panel 7 is laminated to the upper surface of the edge plate 8, it moves to the leveling device 10. The leveling device 10 smooths the lower edge of the edge plate 8 and uses a combination of hot and cold air blown from the leveling device 10 for dust removal, while the hot air heats the leveled area. When the integrated wall panel 7 moves to the end roller 4, it applies the film to the sides of the edge plate 8. Finally, the hot pressing roller 9 and the edge-gathering roller 5 gather the surface film, so that the excess surface film adheres to the lower part of the integrated wall panel 7.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
