Function components are arranged on one side of the vertical plate, and power components are arranged on the other side of the vertical plate. The function components include a left film feeding device 1, a right paper feeding device 2, and an intermediate laminating device 3.

[0031] In some specific embodiments of the present utility model, the functional components may further include a paper receiving device to increase production, and at the same time, there is no need to consider the problem of product storage.

[0032] For the left film releasing device 1, the left film releasing device 1 is used to release the film.

[0034] During use, a drum is installed on the film releasing shaft 7. A large amount of film is pre-wound on the drum. Then, the film releasing shaft 7 is rotated, and the film is unwound and unfolded by the film releasing shaft 7. Next, the film is tensioned and flattened by the guide rollers 8. Then, the film passes through the gap between the lower guide roller and the upper pressing roller and moves to the gluing device 4.

[0035] The first clamping assembly includes a first lower guide roller 9 and a first upper pressing roller 10 located above the first lower guide roller 9, which can delay the film supply, make the film passing through the gluing device 4 flat, and make the glue evenly distributed along the conveying direction of the film.

[0036] Referring to Figure 2 , for the gluing device 4, the gluing device 4 is located above the left film releasing device 1. The gluing device 4 includes a support roller 5 and a glue gun 6.

The plurality of glue spraying assemblies 28 are located above the support roller 5 and are arranged axially along the support roller 5. The glue gun 6 further includes a plurality of control units, and the control units correspond to the glue spraying assemblies 28 to control the plurality of glue spraying assemblies 28 to spray glue onto the film.

[0037] It is easy to understand that in this embodiment, by setting the glue gun 6, the glue application chamber includes a plurality of glue spraying assemblies 28, and the plurality of glue spraying assemblies 28 are arranged axially along the support roller 5, and each glue spraying assembly 28 is connected to a control unit. Therefore, by configuring the control unit, the glue spraying assembly 28 can spray glue or stop spraying glue and spray glue in sequence, generating different glue application modes, producing glue films with different glue application modes to verify the bonding quality, and also facilitating the provision of glue film products produced by different glue application modes, making the equipment have diverse functions, easy to be universal, and have a wide application range.

[0038] For the control unit, the control unit includes a solenoid valve, a sliding component, and a fixing component. The fixing component has a glue containing cavity, and the glue inlet cavity is communicated with the glue containing cavity. The solenoid valve is used to control the sliding component to perform linear reciprocating motion in the fixing component to connect or block the glue containing cavity and the nozzle opening, and further control the glue spraying assembly 28 to spray glue.

[0039] In some specific embodiments of the present utility model, the glue applicator 6 may include a turning frame 13 for mounting a plurality of glue spraying components 28. The turning frame 13 swings up and down to bring the plurality of glue spraying components 28 close to the film on the supporting roller 5.

[0040] It is easy to understand that in this embodiment, by providing the turning frame 13, the glue spraying components 28 swing close to or away from the film, avoiding lifting and lowering directly in the vertical direction, facilitating the separation of the glue spraying components 28 from the film, preventing the film from being lifted and stretched, and avoiding affecting the film quality.

The pressing rod 18 is parallel to the paper feeding shaft 14 and presses against the bottom of the paper feeding shaft 14.

[0043] It is easy to understand that in this embodiment, by providing the paper pressing arm 15, it also prevents the paper roll from loosening rapidly due to unwinding, avoids moisture being sucked in through the gap and affecting the quality of the base paper, and protects the base paper.

[0044] In some specific embodiments of the present utility model, the intermediate laminating device 3 may include a first supporting plate 11 for guiding the film. The first supporting plate 11 is capable of lifting and lowering, and the top surface of the first supporting plate 11 is used to abut against the film.

[0046] In some specific embodiments of the present utility model, the intermediate laminating device 3 may include a first roller group 12 for guiding the film. The first roller group 12 is located above the first supporting plate 11. The first roller group 12 supports the film to enable the film to be away from the glue applicator 6 at different angles.

[0047] It is easy to understand that in this embodiment, by providing the first roller group 12, the film is also enabled to be away from the glue application device 4 at different angles to change the glue application quality, such as the thickness of the glue.

[0048] In some specific embodiments of the present utility model, the glue applicator 6 may include a glue scraping plate. When the film is laminated with the base paper through the first roller group 12, the glue scraping plate abuts against the film to scrape the glue.

[0049] It is easily understandable that in this embodiment, by providing a glue scraping plate, the sprayed glue can be scraped to increase the glue coating width and reduce the influence of the nozzle size and position of the glue spraying assembly 28 on the glue coating quality.

[0050] For the middle laminating device 3, the middle laminating device 3 includes a left pressure roller 19, a right pressure roller 20, and a cylinder 22 that drives the right pressure roller 20 to approach the left pressure roller 19. Sliders 21 are connected to both ends of the right pressure roller 20, and each slider 21 is connected to a cylinder 22.

[0051] It is easily understandable that in this embodiment, by providing the left pressure roller 19 and the right pressure roller 20, the left pressure roller 19 and the right pressure roller 20 clamp the film and the base paper with a certain pressure, which also facilitates the discharge of air and the immersion of glue into the base paper, resulting in high bonding consistency and improved bonding quality.

[0052] Refer to Figure 3 , in some specific embodiments of the present invention, a paper receiving device may be provided below the right paper feeding device 2. The paper receiving device includes a second clamping assembly 23 and a paper receiving shaft 24, and the base paper is wound around the paper receiving shaft 24 after passing through the second clamping assembly 23.

[0053] It is easily understandable that in this embodiment, by providing the paper receiving device, the glue film can be wound up, reducing the on-site occupied space and facilitating storage, which is suitable for mass production.

[0054] In some specific embodiments of the present invention, a third clamping assembly 25 may be provided on the side of the second clamping assembly 23 facing away from the paper receiving shaft 24. The third clamping assembly 25 includes a third upper pressure roller 26 and a third lower guide roller 27 located below the third upper pressure roller 26, and the outer surface of the third upper pressure roller 26 is provided with indentation patterns.
