Technical Field
[0001] This utility model relates to the field of protective film manufacturing technology, specifically to a multilayer composite pressing device for a high-transparency, fade-resistant protective film. Background Technology
[0002] In today's era of rapid technological advancement, high-transparency anti-fading protective films have been widely used in numerous fields. From screen protection for consumer electronics to decoration and protection of high-end architectural glass, and even automotive windows and optical instruments, high-transparency anti-fading protective films, with their excellent optical performance, weather resistance, and anti-fading properties, have become an important material for ensuring product quality and aesthetics.
[0003] High-transparency, fade-resistant protective films are typically composed of multiple layers of film materials with different functions, each layer playing a specific role. For example, the base layer provides basic mechanical support, ensuring the strength and toughness of the protective film; the transparent functional layer gives the protective film high transparency, ensuring that light can pass through smoothly without affecting the visual effect; and the fade-resistant layer effectively blocks harmful rays such as ultraviolet rays, preventing the protective film from fading during use and extending its service life.
[0004] To achieve a perfect bond between these multilayer films, multilayer composite pressing devices have emerged. These devices precisely control parameters such as pressure and time to tightly press the layers of film together to form a whole. However, currently, many multilayer composite pressing devices use the traditional adhesive supply method, which involves applying adhesive to the surface of a certain layer of film manually or with simple mechanical equipment before pressing, and then feeding each layer of film into the pressing device for pressing. This method is time-consuming, labor-intensive, and inefficient.
[0005] Therefore, in order to address the above problems, the applicant needs to design a multi-layer composite pressing device for a highly transparent, fade-resistant protective film to solve the problem. Utility Model Content
[0006] The purpose of this invention is to provide a multilayer composite pressing device for a highly transparent, fade-resistant protective film, in order to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite pressing device for a high-transparency, fade-resistant protective film, comprising a support frame, and a rotating roller rotatably mounted on the support frame.
[0008] It also includes: a pressing roller coupled to the rotating roller, and a linkage rod is provided on the inner side of the pressing roller. The linkage rod is provided with a linkage component, and the linkage component is used to drive the linkage rod to rotate in an arc shape; a glue supply mechanism is provided on the support frame, and the glue supply mechanism supplies glue to the rotating roller. The glue supply mechanism includes a threaded rod rotatably connected to the support frame, and a movable sleeve is threaded on the threaded rod. A fixed frame is fixedly provided on the movable sleeve, and a buffer tank is provided on the fixed frame. A connecting pipe is connected to the buffer tank, and the discharge end of the connecting pipe is connected to a glue supply chamber. A hole is provided on the side of the glue supply chamber near the rotating roller. A limit sleeve is fixedly provided on the movable sleeve, and a sliding rod is slidably provided on the inner side of the limit sleeve. A fixed block is fixedly provided on the sliding rod, and a fixed plate is provided on the fixed block. The fixed plate is fixedly connected to the support frame.
[0009] Furthermore, the linkage component includes a fixed rod that is fixedly connected to the support frame, and a cylinder is provided on the fixed rod. A connector is provided at the output end of the cylinder, and a rotating component is provided on the connector. A sliding sleeve is provided on the rotating component, and the sliding sleeve is rotatably connected to the linkage rod.
[0010] Furthermore, a hollow sleeve is fixedly provided on the rotating component, and a limit rod is rotatably provided on the inner side of the hollow sleeve, and the limit rod is fixedly connected to the support frame.
[0011] Furthermore, one end of the rotating roller is provided with a coupling that is fixedly connected to the support frame, and a servo motor is provided on the coupling.
[0012] Furthermore, a reinforcing plate is fixedly installed on the glue supply hopper, and the reinforcing plate is fixedly connected to the movable sleeve.
[0013] Furthermore, one end of the threaded rod is provided with a coupling two that is fixedly connected to the support frame, and a servo motor two is provided on the coupling two.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the multi-layer composite pressing device for the high-transparency anti-fading protective film facilitates the pressing of multi-layer protective films and can automatically supply adhesive during the pressing process, thereby improving the pressing quality and efficiency. The specific details are as follows:
[0015] In use, the multi-layer composite pressing device for this high-transparency, fade-resistant protective film uses a servo motor 2 to drive a threaded rod to rotate via a coupling 2. This drives a movable sleeve and a glue supply mechanism fixed thereon to move at a uniform speed along the axial direction of the rotating roller. Simultaneously, the adhesive in the buffer tank is transported to the glue supply bin through a connecting pipe and evenly coated onto the surface of the rotating roller through the side wall holes. The servo motor 1 drives the rotating roller to rotate via a coupling 1, continuously conveying the glue-coated base film to the pressing station. At the same time, other functional layer films are fed in synchronously. At this point, the cylinder pushes the connecting piece to drive the rotating piece to rotate around the limit rod. The sliding sleeve pulls the linkage rod downward in an arc shape, causing the pressing roller to tightly composite the multi-layer film with controllable pressure. The axial movement of the glue supply mechanism and the circumferential rotation of the rotating roller work together to achieve full coverage of the adhesive. The cylinder dynamically adjusts the pressing force to ensure that the film is bonded without air bubbles, ultimately completing a high-precision, automated multi-layer composite process, improving pressing quality and efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-4As shown, this utility model discloses a multi-layer composite pressing device for a high-transparency, fade-resistant protective film, comprising a support frame 1, on which a rotating roller 10 is rotatably mounted; a pressing roller 11 coupled to the rotating roller 10, with a linkage rod 12 disposed on the inner side of the pressing roller 11, a linkage component disposed on the linkage rod 12, and the linkage component being used to drive the linkage rod 12 to rotate in an arc; and an adhesive supply mechanism 2 disposed on the support frame 1, which supplies adhesive to the rotating roller 10. The adhesive supply mechanism 2 includes a threaded rod 20 rotatably connected to the support frame 1, and the threaded rod 20 has... A movable sleeve 21 is provided with a thread, a fixed frame 22 is fixedly provided on the movable sleeve 21, and a buffer tank 23 is provided on the fixed frame 22. A connecting pipe 24 is connected to the buffer tank 23. The discharge end of the connecting pipe 24 is connected to a glue supply hopper 25. A hole is provided on the side of the glue supply hopper 25 near the rotating roller 10. A limit sleeve 27 is fixedly provided on the movable sleeve 21, and a slide rod 28 is slidably provided inside the limit sleeve 27. A fixed block 29 is fixedly provided on the slide rod 28. A fixed plate 290 is provided on the fixed block 29, and the fixed plate 290 is fixedly connected to the support frame 1.
[0023] The linkage component includes a fixed rod 15 fixedly connected to the support frame 1, and a cylinder 150 is provided on the fixed rod 15. A connector 151 is provided at the output end of the cylinder 150, and a rotating part 152 is provided on the connector 151. A sliding sleeve 155 is provided on the rotating part 152, and the sliding sleeve 155 is rotatably connected to the linkage rod 12. By driving the connector 151 and the rotating part 152 through the cylinder 150, and combined with the sliding sleeve 155 driving the linkage rod 12 to rotate in an arc, the precise lifting and lowering control of the pressing roller 11 is realized, the degree of automation of the pressing process is improved, and the pressure of the multilayer film is uniform and stable in dynamic lamination, thereby improving the bonding quality and production efficiency of the protective film.
[0024] A hollow sleeve 153 is fixedly installed on the rotating component 152. A limit rod 154 is rotatably installed inside the hollow sleeve 153, and the limit rod 154 is fixedly connected to the support frame 1. The rotational engagement structure of the hollow sleeve 153 and the limit rod 154 provides reliable rotational limit support for the rotating component 152, effectively preventing the linkage components from shifting or shaking during the movement, and enhancing the operational stability of the device.
[0025] One end of the rotating roller 10 is provided with a coupling 13 that is fixedly connected to the support frame 1, and a servo motor 14 is provided on the coupling 13.

[0026] A reinforcing plate 26 is fixedly installed on the glue supply tank 25, and the reinforcing plate 26 is fixedly connected to the movable sleeve 21. The reinforcing plate 26 rigidly connects the glue supply tank 25 and the movable sleeve 21 to form a stable glue supply unit as a whole, which effectively counteracts the inertial force generated when the glue supply mechanism 2 moves laterally, prevents the glue supply tank 25 from deviating from the preset position due to vibration, ensures that the glue is accurately coated onto the surface of the rotating roller 10 through the holes, and reduces glue overflow or glue breakage.

The servo motor 201 controls the precise rotation of the threaded rod 20 through the coupling 200, and drives the moving sleeve 21 to drive the glue supply mechanism 2 to reciprocate linearly.
[0028] Working principle: When using the multi-layer composite pressing device for high-transparency, fade-resistant protective film, servo motor 201 drives the threaded rod 20 to rotate via coupling 200, which in turn drives the moving sleeve 21 and the glue supply mechanism 2 fixed thereon to move at a uniform speed along the axis of the rotating roller 10. At the same time, the adhesive in the buffer tank 23 is transported to the glue supply bin 25 through the connecting pipe 24, and is evenly coated onto the surface of the rotating roller 10 through the holes in its side wall. Servo motor 14 drives the rotating roller 10 to rotate via coupling 13, so that the glue-coated base film is continuously transported to the pressing device. At the same time, other functional layer films are fed in simultaneously. At this time, the cylinder 150 pushes the connector 151 to drive the rotating part 152 to rotate around the limiting rod 154. The sliding sleeve 155 pulls the linkage rod 12 to press down in an arc, so that the pressing roller 11 tightly laminates the multi-layer film with controllable pressure. The axial movement of the glue supply mechanism 2 and the circumferential rotation of the rotating roller 10 work together to achieve full coverage of the glue. The cylinder 150 dynamically adjusts the pressing force to ensure that the film is bonded without air bubbles. Finally, a high-precision and automated multi-layer lamination process is completed, improving the pressing quality and efficiency.
