[0022] 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.

[0023] Please see Figure 1-4A widely applicable film slitting device includes a worktable 1, support legs 2, brackets 3, a top plate 4, a lifting device 5, an adjusting assembly, and a cutting assembly. The support legs 2 are located at the four lower corners of the worktable 1, and the brackets 3 are located at the four upper corners of the worktable 1. The top plate 4 is positioned above the four sets of brackets 3. The adjusting assembly includes a sliding frame 6, a motor 7, positive and negative threaded screws 8, a slider 9, and a mounting frame 10. The lifting device 5 passes through the top plate 4 and is connected to the center of the top wall of the sliding frame 6. A sliding groove is provided below the sliding frame 6, and two sets of symmetrically arranged sliders 9 and threaded screws 8 are arranged in the sliding groove. The two sets of sliders 9 are threadedly connected to the threaded screws 8. The output end of the motor 7 passes through the sliding frame 6 and is connected to the threaded screws 8. A mounting frame 10 is also provided below the sliders 9. The cutting assembly includes a blade holder 11, a connector, and a blade body 12. The blade holder 11 is connected to the mounting frame 10 through the connector, and the blade body 12 is also provided below the blade holder 11.

[0024] The four corner supports 2 at the bottom of the worktable provide stable bottom support for the entire device, ensuring that the device is placed stably. The brackets 3 at the four corners above the worktable 1 connect upwards to the top plate 4, forming a frame structure that provides a mounting base for other components such as the lifting device 5 and the adjustment components, ensuring the overall stability of the device. The motor 7 is a servo motor 7, whose output end passes through the slide frame 6 and connects to the threaded screw 8. When the motor 7 starts, it can precisely control the rotation of the threaded screw 8, providing power for adjusting the position of the cutting components. The threaded screw 8 is located in the slide groove below the slide frame 6 and is threadedly connected to two sets of symmetrically arranged sliders 9. Due to the special design of the threaded screw 8, when it rotates, the two sets of sliders 9 will move in opposite directions or backwards along the axis of the screw in the slide groove. This motion method allows for precise adjustment of the distance between the two sliders 9. A mounting frame 10 is connected below the sliders 9. As the sliders 9 move, the mounting frame 10 changes position accordingly, thereby moving the cutting assembly mounted on the mounting frame 10. This allows for adjustment of the cutting spacing to accommodate the cutting requirements of films of different widths. The lifting device 5 uses a cylinder, one end of which passes through the top plate 4 and connects to the center of the top wall of the sliding frame 6. By controlling the extension and retraction of the cylinder, the sliding frame 6 can be raised and lowered vertically. This allows for precise adjustment of the height of the cutting assembly according to the film thickness, ensuring the blade 12 is positioned appropriately for cutting the film, further expanding the device's applicability. A guide rod 16, passing through the top plate 4, is installed on the sliding frame 6. During the raising and lowering of the sliding frame 6, the guide rod 16 acts as a guide, ensuring the sliding frame 6 rises and falls smoothly in the vertical direction, avoiding swaying or deviation, guaranteeing the stability of the cutting assembly during the raising and lowering process, and thus improving cutting accuracy.

[0025] In actual use, the connector includes an elastic element and a locking block 13. Movable grooves are provided on both sides of the blade holder 11. The two ends of the elastic element are connected to the inner wall of the movable groove and the locking block 13, respectively. The mounting frame 10 has locking holes adapted to the locking block 13. The elastic element includes a spring 14 and a telescopic rod 15. The spring 14 is sleeved on the telescopic rod 15. Both ends of the spring 14 and the telescopic rod 15 are connected to the inner wall of the movable groove and one end of the locking block 13, respectively. The blade holder 11 of the cutting assembly is connected to the mounting frame 10 via the connector. The connector consists of an elastic element (a combination of spring 14 and telescopic rod 15) and a locking block 13. Within the movable grooves on both sides of the blade holder 11, the two ends of the elastic element are connected to the inner wall of the movable groove and the locking block 13, respectively. When installing the tool holder 11, align the locking blocks 13 on both sides of the tool holder 11 with the locking holes on the mounting frame 10. The locking blocks 13 automatically engage with the locking holes under the elastic force of the spring 14, enabling quick installation of the tool holder 11 and the mounting frame 10. For disassembly, press the locking blocks 13 to overcome the elastic force of the spring 14 and retract them into the movable grooves, disengaging them from the locking holes. The tool holder 11 can then be removed from the mounting frame 10, facilitating maintenance and replacement of the tool holder 11 and the tool body 12.

[0026] The two mounting frames 10 drive their respective connected blade holders 11 and blade bodies 12, adjusting their positions as the slider 9 moves. During film cutting, the two blade bodies 12 can simultaneously cut the film from both sides. This dual-sided cutting method ensures uniform force on the film during cutting, effectively avoiding the uneven cutting edges caused by uneven force in traditional single-sided cutting, guaranteeing the flatness of the film edges after cutting, and improving subsequent processing quality.

[0027] It is important to note that during cutting, both ends of the film must be kept taut. One end is secured by a winding device, and the other end is positioned by a movable clamping device, which is then used in conjunction with the cutting device for cutting.
