Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum foil paper processing equipment, and in particular to a dry lamination device for aluminum foil paper. Background Technology
[0002] Aluminum foil lamination is a process that combines aluminum foil with a substrate (such as paper), primarily used to enhance material properties or meet specific application requirements. The process involves first selecting suitable aluminum foil and a substrate, and preparing appropriate adhesives. Next, the adhesive is evenly coated onto the substrate, then dried in an oven to remove solvents and cure the adhesive. Afterward, the treated aluminum foil and substrate are bonded together under pressure to ensure a strong bond. Subsequently, natural cooling and curing steps are performed to stabilize the composite material structure. Finally, the laminated material is cut, slit, and rolled according to actual needs, thus completing the entire lamination process.
[0003] In the pressure lamination process of aluminum foil, the adhesive applied to the substrate surface retains a certain temperature after drying in an oven. This temperature is crucial for ensuring a strong and reliable bond in subsequent pressure lamination steps. Ideally, this heat helps maintain the adhesive's optimal viscosity and flowability, thus promoting a tight bond between the aluminum foil and other materials. However, in actual production operations, especially in cold weather, the adhesive, which has dried but still retains heat on the substrate surface, may experience rapid cooling. This can prevent the adhesive from performing the pressure lamination process at its optimal state, thus affecting the bonding effect. As a result, voids or other defects may appear between the aluminum foil and other materials, severely impacting the quality and performance of the final product. These adverse effects not only reduce yield but can also increase production costs, necessitating improvements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a dry lamination device for aluminum foil paper.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0006] A dry laminating apparatus for aluminum foil includes a frame, multiple guide rollers mounted on the frame, a laminating roller rotatably mounted on the frame, a drive mechanism one for driving the laminating roller, a pressing roller mounted on the frame and cooperating with the laminating roller, and a drive mechanism two for driving the pressing roller to oscillate; the laminating roller is a hollow roller with one end open; a heating tube is fixedly connected to the frame, and the heating tube extends into the laminating roller from the open end of the laminating roller.
[0007] Preferably, the drive mechanism includes a geared motor fixedly connected to the frame, a rotating shaft fixedly connected to the output end of the geared motor, and a transmission mechanism for driving and connecting the rotating shaft and the composite roller; the rotating shaft is rotatably mounted on the frame.
[0008] Preferably, the pressing roller includes a pressing section in the middle and connecting sections at both ends of the pressing section; the transmission mechanism is a sprocket transmission mechanism, which includes a driving sprocket fixedly connected to the rotating shaft, a driven sprocket fixedly connected to the corresponding connecting section, and a chain meshing the driving sprocket and the driven sprocket.
[0009] Preferably, the second drive mechanism consists of two sets, located at both ends of the pressing roller. The second drive mechanism includes a swing arm hinged to the frame in the middle and a cylinder. The cylinder includes a piston rod and a cylinder body. One end of the swing arm is rotatably connected to the pressing roller, and the other end is rotatably connected to the end of the piston rod. The tail of the cylinder body is rotatably connected to the frame. When the piston rod of the cylinder extends or retracts, it drives the swing arm to swing forward and backward, thereby pushing the pressing roller closer to or away from the composite roller.
[0010] Preferably, the cylinder body is connected to the frame via a connecting seat.
[0011] Preferably, the heating element is provided with a fixing seat, which is fixed to the frame by screws; the frame is provided with a through hole for the heating element to pass through.
[0012] Preferably, the composite roller is connected to the frame via a mounting base with a through hole in the middle.
[0013] The above technical solution has the following advantages:
[0014] This invention employs a hollow composite roller with a heating element installed inside, and is equipped with a suitable drive mechanism to ensure smooth rotation. As the composite roller rotates during operation, the built-in heating element provides comprehensive heating, instantly preheating the substrate near the roller. This ensures that both the substrate and aluminum foil maintain a suitable temperature range during lamination, effectively avoiding problems caused by excessively low ambient temperatures. Specifically, at lower ambient temperatures, adhesives often fail to reach their optimal working state, directly affecting the bonding effect during pressure lamination. However, by using this heated composite roller, even under cold conditions, the adhesive maintains its ideal flowability and viscosity, achieving a stronger and more reliable bond, overcoming various defects caused by insufficient temperature in traditional processes. This invention not only improves the quality of the final product but also enhances the stability and efficiency of the production process. Attached Figure Description

Detailed Implementation
[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] As shown in the attached figure, a dry lamination device for aluminum foil includes a frame 1, multiple guide rollers 2 mounted on the frame 1, a lamination roller 3 rotatably mounted on the frame 1, a drive mechanism 4 for driving the lamination roller 3, a pressing roller 5 mounted on the frame 1 and cooperating with the lamination roller 3, and a drive mechanism 6 for driving the pressing roller 5 to swing. The lamination roller 3 is a hollow roller with one end open. A heating tube 7 is fixedly connected to the frame 1, and the heating tube 7 extends into the lamination roller 3 from the open end of the lamination roller 3.
[0027] As a specific technical solution in this embodiment, the drive mechanism 4 includes a reduction motor 8 fixedly connected to the frame 1, a rotating shaft 9 fixedly connected to the output end of the reduction motor 8, and a transmission mechanism 10 that drives and connects the rotating shaft 9 and the composite roller 3; the rotating shaft 9 is rotatably mounted on the frame 1. The pressing roller 5 includes a pressing section 14 in the middle and connecting sections 15 located at both ends of the pressing section 14; the transmission mechanism 10 is a high-temperature resistant sprocket transmission mechanism, which includes a driving sprocket 11 fixedly connected to the rotating shaft 9, a driven sprocket 12 fixedly connected to the corresponding connecting section 15, and a chain 13 meshing with the driving sprocket 11 and the driven sprocket 12. Obviously, the transmission mechanism 10 can also adopt a suitable transmission mechanism such as a gear transmission mechanism.
[0028] As a specific technical solution in this embodiment, the second driving mechanism 6 consists of two sets, located at both ends of the pressing roller 5. The second driving mechanism 6 includes a swing arm 16 hinged to the frame 1 in the middle, and a cylinder 17. The cylinder 17 includes a piston rod 18 and a cylinder body 19. One end of the swing arm 16 is rotatably connected to the pressing roller 5, and the other end is rotatably connected to the end of the piston rod 18. The tail of the cylinder body 19 is rotatably connected to the frame 1. When the piston rod 18 of the cylinder 17 extends or retracts, it drives the swing arm 16 to swing forward and backward, thereby pushing the pressing roller 5 closer to or away from the composite roller 3. When the pressing roller 5 is in contact with the composite roller 3, pressure bonding of the aluminum foil and the substrate can be achieved. When the pressing roller 5 is away from the composite roller 3, it facilitates the threading of the aluminum foil and the substrate.
[0029] As a specific technical solution in this embodiment, the cylinder body 19 is connected to the frame 1 via a connecting seat 20 to facilitate installation and maintenance.
[0030] As a specific technical solution in this embodiment, the heating tube 7 is provided with a fixing seat 21, which is fixed to the frame 1 by screws 22; the frame 1 is provided with a through hole (not shown in the figure) for the heating tube 7 to pass through. The fixing seat 21 facilitates the quick assembly and disassembly of the heating tube 7. The heating tube 7 is preferably made of constant temperature PTC heating material, but a temperature controller can also be used for temperature control.
[0031] As a specific technical solution in this embodiment, the composite roller 3 is connected to the frame 1 through a mounting base 23 with a through hole in the middle, thereby improving the convenience of assembly and disassembly.
[0032] When the composite roller 3 rotates during operation, the built-in heating tube 7 remains stationary. When powered on, it heats the composite roller 3 comprehensively, thereby preheating the substrate close to the composite roller 3 in an instant. This ensures that the substrate and aluminum foil can be maintained within a suitable temperature range during the lamination process, effectively avoiding various defects caused by excessively low ambient temperatures.
