[0002] Composite doors are made from two or more primary materials, typically consisting of an inner frame, a door core, and decorative panels. The materials and construction of each component determine performance, quality, and price. Composite doors undergo a series of scientific processes, including drying, cutting, planing, mortising, drilling, high-speed milling, pressing, polishing, and painting. After processing, composite door panels require a protective film coating to prevent scratches during storage and transportation, which could affect their appearance and sales.

[0003] Some existing film application methods rely on manual labor. This involves first securing a roll of protective film to one end of the door panel, then pulling the film to apply it to the door panel. Tools are then used to press the film onto the door panel, and scissors are used to cut away any excess film at the edges. This completely manual process is associated with low efficiency and high labor intensity. Furthermore, manual cutting during the film application process can easily lead to skewed edges, resulting in poor results. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1 、 Figure 2 and Figure 3As shown, an embodiment of the present invention proposes: a film-sticking device for a composite door panel, comprising a pressing piece 1, a tensioning assembly 2 and a cylinder 4. The pressing piece 1 is fixedly connected to the movable end of the cylinder 4 through a connecting frame 3, and the cylinder 4 is fixedly connected to the frame of the workbench, so that the pressing piece 1 and the cylinder 4 can be stably installed on the workbench. During use, the film can be used together with the film unfolding equipment. After the film is unfolded, it is pressed and covered on the composite door panel placed on the workbench to complete the film-sticking operation on the composite door panel. The cylinder 4 is driven by the pressure when it is running. As the pressing member 1 moves up and down, the film is squeezed so that the film can be stably attached to the composite door panel, thereby smoothly completing the film application. A pressing airbag 102 is arranged in the cavity provided on the first shell 101 of the pressing member 1, which is convenient for the pressing airbag 102 to press the film during use, so that the film can be stably attached to the composite door panel, thereby improving the speed and quality of film application. The pressing airbag 102 is connected to the telescopic airbag 104 through the connecting air pipe 106, and the lower part of the telescopic airbag 104 is fixedly connected to the cutting The knife 105, the telescopic airbag 104 and the cutting knife 105 are all placed in the second shell 103, so that when the squeezing and pressing airbag 102 is deformed, the squeezed gas enters the telescopic airbag 104, causing the telescopic airbag 104 to deform, and then the cutting knife 105 is pushed out of the second shell 103 to cut the film, and the excess film on the four sides of the composite door panel after the film is applied is cut off. In addition, the tensioning assembly 2 is placed at both ends of the first shell 101, and the tensioning roller 201 of the tensioning assembly 2 is connected to the roller shaft 20 2 is rotatably connected to the mounting frame 203, and the mounting frame 203 is fixedly connected to the first shell 101 through the connecting seat 205. An elastic support plate 206 is installed between the mounting frame 203 and the connecting seat 205, so that when the pressing piece 1 moves down to press the film onto the composite door panel, the tensioning assembly 2 moves down together and first contacts the film. Then, under the action of stress, the tensioning roller 201 rotates toward the two ends of the pressing piece 1, thereby tensioning the film so that the film can be evenly covered and adhered to the composite door panel, thereby improving the quality of the lamination.

[0024] like Figure 1 and Figure 2As shown, in some embodiments, the pressed airbag 102 is composed of a hard connecting seat 1021 and a soft airbag 1022. The hard connecting seat 1021 is fixedly connected to the cavity provided on the first shell 101, so that the pressed airbag 102 can be stably installed in the first shell 101 for stable use, and one end of the communicating air pipe 106 is fixedly connected to the air hole provided at the corresponding position on the hard connecting seat 1021, and the other end of the communicating air pipe 106 passes through the through-hole provided at the corresponding position on the second shell 103 and is fixedly connected to the air hole provided at the corresponding position on the telescopic airbag 104, so that the soft airbag 1022 of the pressed airbag 102 can be pressed against the membrane and the composite door panel during use. , deformation occurs under continuous extrusion, and the gas is squeezed into the telescopic airbag 104 from the communicating air pipe 106, causing the telescopic airbag 104 to deform, pushing the cutting knife 105 to slide in the second shell 103, so that the cutting knife 105 is pushed out, cutting the film covering the composite door panel, and stably pressing the film to the composite door panel during the extrusion process, completing the film laminating operation. After the film is cut, the pressing airbag 102 is separated from the composite door panel, and the pressing airbag 102 loses the extrusion and returns to its original shape. The gas in the telescopic airbag 104 flows back into the pressing airbag 102 from the communicating air pipe 106 again, thereby causing the cutting knife 105 to slide back into the second shell 103;

[0025] The upper end of the telescopic airbag 104 is fixedly connected to the inner wall of the second shell 103, and the lower end is fixedly connected to the connection base provided on the upper part of the cutting knife 105. The cutting knife 105 is slidably connected to the internal cavity of the second shell 103 through the connection base. When the telescopic airbag 104 is deformed, it drives the cutting knife 105 to slide smoothly in the second shell 103, pushing the cutting knife 105 out of the second shell 103 to cut the film on the composite door panel.

[0026] The second shell 103 is fixedly connected to the placement cavity formed by the four sides of the first shell 101 and the pressed airbag 102, and the lower part of the second shell 103 is provided with a knife outlet groove for cooperating with the cutting knife 105 to slide up and down, so that the cutting knife 105 can slide smoothly in the second shell 103, cut the film covering the composite door panel, and smoothly complete the film-sticking operation of the composite door panel.

[0027] like Figure 1 and Figure 3As shown, in some embodiments, a connecting rod 204 is fixedly connected between the mounting frames 203 at both ends of the tensioning roller 201, so as to stably connect the two mounting frames 203 together to form a whole, thereby ensuring stable use, and the roller shaft 202 on the tensioning roller 201 is rotatably connected to one end of the mounting frame 203 through a bearing, so as to stably install the tensioning roller 201 on the mounting frame 203, while ensuring that it can rotate smoothly during use, so as to facilitate stable use, and the other end of the mounting frame 203 is rotatably connected to the rod shaft 2052 set on the connecting seat 205 through a bearing. The connecting base 205 is connected to the first shell 101 by bolts, so that the connecting base 205 can be stably installed on the first shell 101, thereby stably installing the entire tensioning assembly 2 on the pressing piece 1, so that the two can be stably used together. At the same time, during use, it can be ensured that when the mounting frame 203 is subjected to force, it can generate appropriate rotation on the connecting base 205, so that the tensioning roller 201 rotates toward the two ends of the pressing piece 1, thereby tensioning the film to be pressed, so that the film can be evenly covered and attached to the composite door panel, thereby improving the quality and efficiency of film application.

[0028] The connecting shaft arranged at the corresponding position on the mounting frame 203 is rotatably connected to the connecting ear plate integrally arranged at the lower end of the elastic support plate 206, and the upper end of the elastic support plate 206 is rotatably connected to the connecting shaft arranged at the corresponding position on the support rod 2051 on one side of the connecting seat 205. When the elastic support plate 206 can be deflected between the mounting frame 203 and the connecting seat 205, appropriate deformation will be generated accordingly. Both ends of the elastic support plate 206 adopt a rotating connection method, which can ensure appropriate rotation when deformation occurs, thereby ensuring smooth use. At the same time, when the external force is lost, the elastic support plate 206 can drive the mounting frame 203 to return to its original position with the tensioning roller 201, ensuring stable use.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
