Description

Technical Field

[0001] The utility model relates to the technical field of decorative paper production and processing, in particular to a decorative paper surface film laminating device. Background Art

[0002] At present, a decorative paper surface film laminating device is a device used to cover a layer of film on the surface of decorative paper. Its main purpose is to improve the protection, aesthetics and durability of decorative paper. The decorative paper surface film laminating device is an automated device that combines mechanical, electrical and control technologies and can evenly and quickly cover a layer of film on the surface of decorative paper.

[0003] In the Chinese utility model patent with the publication number of CN220261997U, a decorative paper surface film laminating machine is disclosed. In the above prior art, although the second electric telescopic rod is started to move the push plate by the moving base to evenly squeeze and align the edges, during the film laminating process, the tension of the film and the decorative paper is particularly important. Because when the glue is not stored well, it will cause the decorative paper to absorb too much water or the glue to be too dry, resulting in slight deformation of the decorative paper. In this way, the adhered decorative paper will also produce wrinkles and deformations, and after drying and shaping, it will be unable to be changed and unusable, causing waste. Therefore, it is necessary to design a decorative paper surface film laminating device that can make the film and the decorative paper flat by changing the overall tension after the film and the decorative paper are squeezed and adhered together. Summary of the Utility Model

[0004] To solve the technical problem that the decorative paper film laminating will produce deformation when the glue is not stored well, the utility model provides a decorative paper surface film laminating device.

[0005] The utility model is realized by adopting the following technical solutions: A decorative paper surface film laminating device includes two support frames. Between the two support frames, there is a first unwinding assembly for unwinding decorative paper. On one side of the first unwinding assembly, there is a second unwinding assembly for unwinding film. On one side of the first unwinding assembly, there is a glue coating assembly. Between the two support frames, there is also a winding assembly for winding the film-laminated decorative paper. On one side of the winding assembly, there is a drying assembly for drying the film-laminated decorative paper. On one side of the drying assembly, there is an extrusion assembly for extruding and laminating the decorative paper and the film. Between the drying assembly and the extrusion assembly, there is a tension assembly for changing the tension of the film-laminated decorative paper. On both sides of the tension assembly, there are moving assemblies for adjusting the position of the tension assembly. The tension assembly includes a rotating shaft arranged between the two support frames and an adjusting roller rotatably sleeved on the rotating shaft.

[0006] Through the above technical solution, after the film and the decorative paper are squeezed together by the squeezing assembly, the tension assembly will lift the coated decorative paper, increasing the tension of the decorative paper. In this way, the bulges and slight deformations of the decorative paper will be flattened due to the tension, preventing the decorative paper from deforming after drying.

[0007] As a further improvement of the above solution, sliding grooves are provided on the opposite surfaces of the two support frames. The moving assembly includes a moving plate disposed between the two support frames and sliding blocks slidably installed inside each sliding groove.

[0008] Through the above technical solution, when the moving plate moves up and down, the adjusting roller will also move accordingly, thereby changing the tension on the decorative paper.

[0009] As a further improvement of the above solution, one end of the moving plate is fixedly installed with an adjacent sliding block, and a first threaded column is fixedly installed at the other end of the moving plate. A threaded sleeve rotatably installed with an adjacent sliding block is threadedly sleeved on the first threaded column.

[0010] Through the above technical solution, when the threaded sleeve rotates, it will move relative to the first threaded column, thereby exerting a squeezing effect on the moving plate and enabling the moving plate to fix the position of the tension assembly.

[0011] As a further improvement of the above solution, a plurality of push bars arranged in central symmetry are fixedly installed on the circumferential surface of the threaded sleeve.

[0012] Through the above technical solution, the push bars will make the rotation of the threaded sleeve more convenient.

[0013] As a further improvement of the above solution, positioning plates are fixedly installed at both ends of the rotating shaft, and one end of each of the two positioning plates penetrates through the moving plate.

[0014] Through the above technical solution, when the positioning plate moves upward, the adjusting roller will also move, thereby changing the tension on the decorative paper.

[0015] As a further improvement of the above solution, second threaded columns are provided on one side of each of the two positioning plates. One end of each of the two second threaded columns threadedly penetrates through the moving plate and is fixedly installed with a rotating block.

[0016] Through the above technical solution, when the second threaded column rotates, the position of the positioning plate will be fixed.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a tension assembly and a moving assembly, when the decorative paper and the film are pressed and bonded together by the pressing assembly, the position of the moving assembly is roughly adjusted according to the tension required for the film-covered decorative paper. Then, the position of the tension assembly is finely adjusted so that the tension assembly can support the film-covered decorative paper. In this way, the bulges and slight deformations of the film-covered decorative paper will be lifted by the tension assembly to maintain a flat unfolded state. This setting can prevent the decorative paper from deforming due to glue and its own tension, thereby improving the production yield of the film-covered decorative paper.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0025] Please refer to Figures 1-3, A surface film laminating device for decorative paper in this embodiment includes two support frames 1. Between the two support frames 1, there is a first unwinding assembly 2 for unwinding decorative paper. On one side of the first unwinding assembly 2, there is a second unwinding assembly 3 for unwinding the film. On one side of the first unwinding assembly 2, there is a glue coating assembly 4. Between the two support frames 1, there is also a winding assembly 5 for winding the film-laminated decorative paper. On one side of the winding assembly 5, there is a drying assembly 6 for drying the film-laminated decorative paper. On one side of the drying assembly 6, there is a pressing assembly 7 for pressing and laminating the decorative paper and the film together. Between the drying assembly 6 and the pressing assembly 7, there is a tension assembly for changing the tension of the film-laminated decorative paper. On both sides of the tension assembly, there are moving assemblies for adjusting the position of the tension assembly. The tension assembly includes a rotating shaft 801 arranged between the two support frames 1 and an adjusting roller 802 rotatably sleeved on the rotating shaft 801. After the film and the decorative paper are pressed together by the pressing assembly 7, the tension assembly will lift up the film-laminated decorative paper, increasing the tension of the decorative paper. In this way, the bulges and slight deformations of the decorative paper will be flattened due to the tension, so that the decorative paper will not deform after drying.

[0026] Combined with Figure 2 and Figure 3 , on the opposite surfaces of the two support frames 1, sliding grooves are respectively formed. The moving assembly includes a moving plate 901 arranged between the two support frames 1 and sliding blocks 902 slidably installed inside each sliding groove. One end of the moving plate 901 is fixedly installed with the adjacent sliding block 902. The other end of the moving plate 901 is fixedly installed with a first threaded column 10. A threaded sleeve 11 rotatably installed with the adjacent sliding block 902 is threadedly sleeved on the first threaded column 10. On the circumferential surface of the threaded sleeve 11, a plurality of push bars 12 arranged in central symmetry are fixedly installed. When the moving plate 901 moves up and down, the adjusting roller 802 will also move together, thereby changing the tension of the decorative paper. When the threaded sleeve 11 rotates, it will move relative to the first threaded column 10, thereby generating a squeezing effect on the moving plate 901, enabling the moving plate 901 to fix the position of the tension assembly.

[0027] Combined with Figure 2 and Figure 3 , both ends of the rotating shaft 801 are fixedly installed with positioning plates 13. One end of each of the two positioning plates 13 penetrates through the moving plate 901. On one side of each of the two positioning plates 13, there is a second threaded column 14. One end of each of the two second threaded columns 14 threadedly penetrates through the moving plate 901 and is fixedly installed with a rotating block. When the positioning plate 13 moves upward, the adjusting roller 802 will also move, thereby changing the tension of the decorative paper.

[0028] In the embodiment of the present application, the implementation principle of a surface film laminating device for decorative paper is as follows: when the film and the decorative paper are squeezed and bonded together by the squeezing assembly 7, the position of the moving plate 901 is adjusted according to the required tension of the decorative paper. Rotating the threaded sleeve 11 can reduce the squeezing force of the first threaded post 10 on the sliding block 902 and the moving plate 901, so that the moving plate 901 can move up and down. After the position of the moving plate 901 is adjusted, the cooperation of rotating the threaded sleeve 11 in the reverse direction with the first threaded post 10 can fix the moving plate 901. Then, slide the positioning plate 13 to make the adjusting roller 802 contact the film-laminated decorative paper, so as to precisely control the tension. After the tension is controlled, rotating the second threaded post 14 can fix the position of the positioning plate 13, so that the adjusting roller 802 can always change the tension of the film-laminated decorative paper. In this way, the bulges and slight deformations of the film-laminated decorative paper will be lifted by the adjusting roller 802 to maintain a flat unfolded state. Such a setting can prevent the film-laminated decorative paper from deforming due to glue and its own tension problems, thereby improving the production yield of the film-laminated decorative paper.

[0029] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present utility model belong to the protection scope required by the present utility model.
