[0001] This utility model relates to the field of protective film preparation, specifically a slitting device for preparing PET protective film. Background Technology

[0002] Screen protectors can be categorized by their application, including digital product protectors, automotive protectors, household protectors, and food preservation protectors. With the widespread use of mobile phones and other digital products in China, "screen protector" has gradually become a general term for screen protectors, and their functions within the screen protector field are incredibly diverse.

[0003] Patent CN213011143U discloses a slitting device for producing a buffered multilayer antistatic protective film. This slitting device includes a base plate with four support columns on its top outer wall. A first fixing frame and a second fixing frame are also provided on the top outer wall of the base plate. A feeding roll is rotatably connected to the first fixing frame. A fixing plate is provided on the top outer wall of the four support columns. A flattening mechanism and a fixing column are respectively provided on the top outer wall of the fixing plate. A slitting plate is provided on one side of the fixing column. This invention, by setting a slitting plate, a slide rail, and cutters, allows the cutters to slide on the slide rail on the slitting plate, thereby adjusting the distance between each cutter. After adjusting the distance between the cutters, the cutters are fixed to the slitting plate with screws, allowing the slitting device to cut protective films of different widths, effectively improving the applicability of the slitting device.

[0004] While the aforementioned patents can effectively cut protective films, the production of protective films may involve adhesives or dust attracted by electrostatic adsorption. After the cut protective film is rolled up, it is not convenient to disassemble the roll roller. After long-term use, material residue is easily left on the roller surface. The inability to disassemble leads to difficulty in cleaning and affects the subsequent slitting quality. Therefore, we propose a slitting device for PET protective film preparation to solve the above problems. Utility Model Content

[0023] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-5 As shown.

[0024] A slitting device for preparing PET protective film includes a base plate 1. Two support plates 9 are connected to the upper surface of the base plate 1. A drive motor 10 is connected to the outer surface of one of the support plates 9. First bearings 11 are embedded in the sides of the two support plates 9 that are close to each other. Rotating columns 12 are connected to the inner rings of the two first bearings 11. One end of one rotating column 12 is connected to the output end of the drive motor 10. Fixed plates 13 are connected to the ends of the two rotating columns 12 that are close to each other. A worm gear 14 is provided on the outer surface of each fixed plate 13. A first gear 15 is connected to the outer surface of each worm gear 14. A second gear 16 is hinged to the interior of each fixed plate 13 via a pin. Each first gear 15 meshes with a second gear 16. Multiple transverse grooves 17 are formed on the outer surface of each fixed plate 13. A transverse slider 1 is slidably connected to the inner wall of each transverse groove 17. 8. Each transverse slider 18 has a clamping plate 21 connected to its outer surface. The outer surfaces of the two second gears 16 are provided with multiple arc-shaped grooves 19. The inner wall of each arc-shaped groove 19 is slidably connected to a first slide rod 20. One end of each first slide rod 20 is connected to the outer surface of the transverse slider 18. By rotating the worm gear 14, the first gear 15 is driven to rotate. Because the first gear 15 meshes with the second gear 16, the second gear 16 uses the rotation of the first gear 15 to make the first slide rod 20 slide inside the arc-shaped groove 19. This causes the first slide rod 20 to drive the transverse slider 18 to slide inside the transverse groove 17, thereby causing the transverse slider 18 to drive the clamping plate 21 to be adjusted. The clamping plate 21 can be effectively adjusted, allowing for quick installation and disassembly of the material receiving assembly, which is beneficial for the long-term use of the device and increases its flexibility.

[0025] In this embodiment, multiple sets of support components 2 are formed on the outer surface of the base plate 1. Each set of support components 2 includes a first threaded hole 201. An adjusting rod 202 is threadedly connected to the inner wall of each first threaded hole 201. A screw block 203 is connected to the top of each adjusting rod 202, and a base 204 is connected to the bottom of each adjusting rod 202. By rotating the screw block 203, the adjusting rod 202 rotates inside the first threaded hole 201, which can effectively support the device and adjust its height. To enhance the stability and convenience of the device, an unwinding assembly 3 is connected to the upper surface of the base plate 1. The unwinding assembly 3 includes two support plates 301. Each support plate 301 has a second bearing 302 embedded on one side that is close to each other. The inner rings of the two second bearings 302 are connected to a rotating rod 303. A feeding roller 304 is connected to the outer surface of the rotating rod 303. When the material is being taken in, the rotating rod 303 rotates using the second bearings 302, thereby causing the feeding roller 304 to rotate on the outer surface of the rotating rod 303 to feed the material.

[0026] In this embodiment, a leveling assembly 4 is connected to the upper surface of the base plate 1. The leveling assembly 4 includes a leveling platform 401. Multiple rollers 403 are connected inside the leveling platform 401 via a first pin 402. Two grooves 404 are formed on the outer surface of the leveling platform 401. Electric push rods 405 are connected inside the two grooves 404. The output ends of the two electric push rods 405 are connected to an adjusting plate 406. A heating plate 407 is connected to the bottom surface of the adjusting plate 406. The adjusting plate 406 is adjusted by the electric push rods 405, thereby heating and leveling the protective film by the heating plate 407. At the same time, the protective film can flow normally by using the first pin 402 and the rollers 403, which increases the flexibility of the device. A placement groove 7 is formed on the outer surface of the support frame 601. A scale 8 is connected inside the placement groove 7. The moving block 603 can be quickly adjusted by the scale 8 inside the placement groove 7, making the adjustment more accurate.

[0027] In this embodiment, a slitting assembly 6 is connected to the upper surface of the base plate 1. The slitting assembly 6 includes a support frame 601, and a second slide rod 602 is connected inside the support frame 601. Multiple moving blocks 603 are slidably connected to the outer surface of the second slide rod 602. A blade 604 is connected to the bottom surface of each moving block 603. By sliding the moving block 603 on the outer surface of the second slide rod 602, the position of the blade 604 can be effectively adjusted, allowing workers to adjust the blade 604 according to different widths, increasing the convenience of the device. The outer surface of the support frame 601 is provided with a fixing component 5. The fixing component 5 includes a second threaded hole 501. The second threaded hole 501 is located on the upper surface of the support frame 601. A fastening bolt 502 is threadedly connected to the inner wall of the second threaded hole 501. The bottom end of the fastening bolt 502 passes through the support frame 601 and is connected to a pressure plate 503. By rotating the fastening bolt 502 inside the second threaded hole 501, the pressure plate 503 is adjusted so that the pressure plate 503 contacts the upper surface of the moving block 603, which can effectively fix the blade 604 and prevent the blade 604 from moving during use.

[0028] Working principle: When in use, rotating the worm gear 14 drives the first gear 15 to rotate. Since the first gear 15 meshes with the second gear 16, the first gear 15 drives the second gear 16 to rotate, thereby causing the first slide rod 20 to slide the transverse slide block 18 in the transverse slide block 17 inside the arc-shaped slide groove 19. This causes the transverse slide block 18 to drive the clamping plate 21 to fix the receiving assembly. Then, the protective film is wound onto the outer surface of the receiving assembly. Finally, the drive motor 10 is started, causing the rotating column 12 to rotate using the first bearing 11. This causes the rotating column 12 to drive the fixing plate 13 to rotate, thus winding up the cut protective film.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
