Technical Field
[0001] This utility model relates to the field of aluminum profile processing technology, specifically to a film flattening structure for an aluminum profile processing film cutting machine. Background Technology
[0002] Die-cutting machines are mainly used for die-cutting, creasing, and hot stamping of some non-metallic materials, self-adhesive labels, EVA, etc. By applying a certain pressure through the printing plate, the printed products or paperboard are rolled into a certain shape. In the aluminum profile processing and production process, a film cutting machine is needed to cut the film into appropriate sizes, and then a film laminating machine is used to apply the cut film onto the aluminum profile.
[0003] During the operation of current film cutting machines, wrinkles easily occur when the film is conveyed by the conveyor belt, resulting in uneven film that needs to be flattened. Since the width and thickness of the film are different, the existing die-cutting machines cannot adapt to different types of film.
[0004] As disclosed in CN212245562U, a film flattening structure for a film cutting machine uses a motor-controlled conveyor belt to transport the film. A rotating handle drives a gear to rotate, and the meshing gears drive a moving plate and a connecting plate to move. The height of the first and second pressure rollers is controlled to accommodate films of different thicknesses. An adjusting plate is threaded onto different positions of the connecting piece. The first pressure roller pushes uneven areas to both sides, and then the two second pressure rollers flatten both sides of the film. The first and second pressure rollers work together to flatten films of different widths, adapting to various types of film flattening. The operation is simple, convenient, and quick.
[0005] However, this flattening structure lacks protective devices, and the first and second pressure rollers will collide with the conveyor belt, which can easily cause damage to the pressure rollers or the conveyor belt.
[0006] Therefore, we urgently need a film flattening structure for an aluminum profile film cutting machine. Utility Model Content
[0007] The purpose of this utility model is to provide a film flattening structure for an aluminum profile processing film cutting machine, so as to solve the problem mentioned in the background art that the first and second pressure rollers collide with the conveyor belt, which easily causes damage to the pressure rollers or the conveyor belt.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a film flattening structure for an aluminum profile processing film cutting machine, comprising a film cutting machine body and a housing, wherein the housing is fixedly installed on the top left side of the film cutting machine body, and a flattening device is provided on the top of the film cutting machine body, wherein the flattening device comprises a flattening unit, a limiting unit and a pre-pressing unit.
[0009] The flattening unit is located inside the housing, the limiting unit is located on the top right side of the film cutting machine body, and the pre-compression unit is located on the right side of the housing.
[0010] The flattening unit includes a telescopic component, a connecting plate, a spring, a damping rod, a bracket, and a pressure roller. The telescopic component is fixedly installed on the top of the box, the connecting plate is fixedly installed on the bottom of the telescopic component, the spring is fixedly installed at both ends of the bottom of the connecting plate, the damping rod is installed inside the spring, the bracket is fixedly installed at the bottom of the spring, and the pressure roller is installed inside the bracket.
[0011] Preferably, the lower surface of the box is open, allowing the pressure roller to move below the box to flatten the film on the conveyor belt.
[0012] Preferably, the limiting unit includes a fixing block, a threaded rod, a limiting rod, and a limiting plate. The fixing block is fixedly installed at the front and rear ends of the top right side of the film cutting machine body. The threaded rod is rotatably connected to the inside of the two fixing blocks. The limiting rod is fixedly installed at the upper end of the inside of the two fixing blocks. The upper end of the limiting plate is installed on the outside of the threaded rod and the limiting rod.
[0013] Preferably, the threaded grooves on the front and rear sides of the threaded rod are in opposite directions, and the limiting plates are symmetrically distributed on the front and rear sides of the threaded rod and are threadedly connected to the threaded rod. By rotating the threaded rod, the distance between the front and rear limiting plates is adjusted so that the distance between the two limiting plates is equal to the width of the film. Thus, the limiting plates limit the conveying of the film and prevent the film from shifting during conveying.
[0014] Preferably, the pre-compression unit includes a side plate, a second threaded rod, a mounting frame, and a second pressure roller. The side plate is fixedly installed at the lower right end of the housing. The second threaded rod is threadedly connected to the inside of the side plate. The mounting frame is rotatably connected to the bottom of the second threaded rod. The second pressure roller is installed inside the mounting frame.
[0015] Preferably, the side plate has an internal thread, and the threaded rod is threaded into the inside of the side plate. By rotating the threaded rod and connecting it to the side plate, while holding the mounting frame to prevent it from rotating, the mounting frame moves vertically in a straight line, so that the pressure roller comes into contact with the upper surface of the film, thus preventing the conveyed film from warping and affecting the subsequent flattening operation.
[0016] Preferably, the threaded rod does not have a threaded groove in the middle to avoid collision between the front and rear limiting plates.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The film flattening structure of the aluminum profile processing film cutting machine, by setting a flattening unit, reduces the collision between the first pressure roller and the conveyor belt when the first pressure roller collides with the conveyor belt through the support compression spring and damping rod, thereby improving the service life of the device and solving the problem in the background technology that the first and second pressure rollers will collide with the conveyor belt, which can easily cause damage to the pressure rollers or the conveyor belt.
[0019] 2. The film flattening structure of this aluminum profile processing film cutting machine, by setting a limiting unit, adjusts the distance between the two limiting plates by rotating the threaded rod, so that the distance between the two limiting plates is equal to the width of the film, thereby limiting the film conveying by the limiting plates and preventing the film from deviating during conveying.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0026] Please see Figures 1-4 This utility model provides a technical solution:
[0027] Example 1:
[0028] A film flattening structure for an aluminum profile processing film cutting machine includes a film cutting machine body 1 and a housing 2. The housing 2 is fixedly installed on the top left side of the film cutting machine body 1. The lower surface of the housing 2 is open, allowing the pressure roller 306 to move to the bottom of the housing 2 to flatten the film on the conveyor belt. A flattening device is provided on the top of the film cutting machine body 1. The flattening device includes a flattening unit, a limiting unit, and a pre-pressing unit.
[0029] The flattening unit is located inside the housing 2, the limiting unit is located on the top right side of the film cutting machine body 1, and the pre-compression unit is located on the right side of the housing 2.
[0030] The flattening unit includes a telescopic component 301, a connecting plate 302, a spring 303, a damping rod 304, a bracket 305, and a pressure roller 306. The telescopic component 301 is fixedly installed on the top of the housing 2. The telescopic component 301 includes a hydraulic cylinder and a hydraulic rod. The hydraulic cylinder is fixedly installed on the top of the housing 2, and the hydraulic rod is installed at the output end of the hydraulic cylinder. The connecting plate 302 is fixedly installed on the bottom of the telescopic component 301. The spring 303 is fixedly installed at both the front and rear ends of the bottom of the connecting plate 302. The damping rod 304 is installed inside the spring 303. The spring 303 and the damping rod 304 reduce the collision between the pressure roller 306 and the conveyor belt. The bracket 305 is fixedly installed on the bottom of the spring 303. The pressure roller 306 is installed inside the bracket 305 and flattens the film through the pressure roller 306.
[0031] Example 2: Based on Example 1: The limiting unit includes a fixing block 401, a threaded rod 402, a limiting rod 403, and a limiting plate 404. The fixing block 401 is fixedly installed at the front and rear ends of the top right side of the film cutting machine body 1. The threaded rod 402 is rotatably connected to the interior of the two fixing blocks 401. The threaded grooves on the front and rear sides of the threaded rod 402 are in opposite directions. The limiting plate 404 is symmetrically distributed on the front and rear sides of the threaded rod 402 and is threadedly connected to the threaded rod 402. The movable threaded rod 402 adjusts the distance between the two limiting plates 404, making the distance between the two limiting plates 404 equal to the width of the film. This limits the film's movement by the limiting plates 404, preventing the film from shifting during transport. The limiting rod 403 is fixedly installed inside the upper part of the two fixing blocks 401. The limiting rod 403 limits the movement of the limiting plates 404. The upper part of the limiting plates 404 is installed outside the threaded rod 402 and the limiting rod 403.
[0032] Example 3: Based on Example 1: The pre-pressing unit includes a side plate 501, a threaded rod 502, a mounting frame 503, and a pressure roller 504. The side plate 501 is fixedly installed at the lower right side of the housing 2. The side plate 501 has an internal thread, and the threaded rod 502 is threadedly connected to the inside of the side plate 501. By rotating the threaded rod 502 and connecting it to the side plate 501, while holding the mounting frame 503 to prevent it from rotating, the mounting frame 503 moves vertically, allowing the pressure roller 504 to contact the upper surface of the film, preventing the conveyed film from warping and affecting subsequent flattening operations. The threaded rod 502 is threadedly connected to the inside of the side plate 501, and the mounting frame 503 is rotatably connected to the bottom of the threaded rod 502. The pressure roller 504 is installed inside the mounting frame 503. The pressure roller 504 pre-presses the film, making the film adhere tightly to the conveyor belt, which facilitates the subsequent flattening operation of the film.
[0033] Example 4: Based on Example 2: No threaded groove is opened in the middle of the threaded rod 402 to avoid collision between the front and rear limit plates 404.
[0034] In use, place the film to be flattened on the conveyor belt of the film cutting machine body 1, then rotate the threaded rod 402 to adjust the distance between the two limiting plates 404, so that the distance between the two limiting plates 404 is equal to the width of the film. Then rotate the threaded rod 502 to move the mounting frame 503 down, so that the pressure roller 504 reaches the appropriate position. Then start the film cutting machine body 1 to convey the film, and use the limiting plates 404 to limit the film and prevent the film from shifting. When the film moves to below the pressure roller 504, the pressure roller 504 presses the film. Pre-compression ensures the film adheres tightly to the conveyor belt. When the film moves below pressure roller 306, it is flattened by the pressure roller 306. When flattening films of different thicknesses is required, the telescopic component 301 is activated to move the connecting plate 302 and the bracket 305 up and down, adjusting the distance between pressure roller 306 and the upper surface of the conveyor belt to process films of different thicknesses. When pressure roller 306 collides with the conveyor belt, the bracket 305 compresses the spring 303 and the damping rod 304 to reduce the collision between pressure roller 306 and the conveyor belt, thus improving the service life of the device.
