Description

Technical Field

[0001] This utility model relates to the field of thin film processing technology, specifically a thin film slitting device. Background Technology

[0002] A thin film is a thin, flexible, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is a two-dimensional material formed by the deposition of atoms, molecules, or ions on a substrate surface. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. After film production, width slitting is required. Currently, the spacing between the blades in existing film slitting devices is not easily adjustable, which hinders the slitting of films of different widths, making it inconvenient to use and unable to adequately meet practical application needs.

[0003] A search revealed a PU film slitting device with application number CN202322700264.5, belonging to the field of PU film processing technology. It includes a fixed frame, with a feeding roller and a receiving roller rotatably mounted on both sides of the upper end of the fixed frame, and a support column fixedly connected to the middle of the fixed frame. The support column is equipped with a cutting mechanism and an adjustment mechanism. This technical solution also suffers from the aforementioned technical problems. Utility Model Content

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 1-6A film slitting device includes a base 1, a central shell 2 rotatably mounted above the base 1, a plurality of slitting blades 3 movably mounted on the surface of the central shell 2, a square frame 16 inside the slitting blades 3, the inner wall of the square frame 16 slidably connected to the surface of the central shell 2, the square frame 16 being made of metal and connected to the slitting blades 3 by welding, baffles 17 being fixedly connected to the top and bottom of the square frame 16, the baffles 17 contacting the slitting blades 3, the spacing between every two adjacent slitting blades 3 being adjustable, a support plate 4 fixedly connected to one side of the top of the base 1, a support shaft 5 rotatably connected to the side of the support plate 4, a bearing 23 being disposed in a groove on the side of the support plate 4, the inner wall of the inner ring of the bearing 23 being fixedly welded to the surface of the support shaft 5. The outer ring of bearing 23 is fixedly welded to the support plate 4. The inner and outer rings of bearing 23 can rotate relative to each other, which allows the support shaft 5 to rotate relative to the support plate 4. However, the support shaft 5 will not detach from the support plate 4. The side of the central shell 2 is fixedly connected to the end of the support shaft 5. A movable plate 6 is provided on the other side of the top of the base 1. A slitting motor 7 is installed on the upper part of the side of the movable plate 6. A drive shaft 8 is fixedly connected to the output shaft of the slitting motor 7. A drive disk 9 is fixedly connected to the end of the drive shaft 8. A drive rod 10 is fixedly connected to the side of the drive disk 9. The end of the drive rod 10 away from the drive disk 9 is movably inserted into the central shell 2. There are two drive rods 10, which are symmetrically arranged on the drive disk 9. The rear side of the central shell 2 is open.

[0024] Please see Figure 1-6 A disassembly groove 11 is provided on the right side of the top of the base 1. A track 12 is fixedly connected to one side of the inner wall of the disassembly groove 11. A slider 13 is slidably connected to the surface of the track 12. The top of the slider 13 is fixedly connected to the bottom of the moving plate 6. A limit plate 14 is fixedly connected to the side of the moving plate 6. A limit rod 15 is movably connected to the top of the limit plate 14. The bottom end of the limit rod 15 extends downward and passes through the track 12. A pull plate 24 is fixedly connected to the top of the limit rod 15. A tension spring 25 is sleeved on the surface of the limit rod 15. One end of the tension spring 25 is fixedly connected to the limit plate 14, and the other end of the tension spring 25 is fixedly connected to the pull plate 24.

[0025] Please see Figure 1-6An adjusting plate 18 is provided inside the central shell 2. Several adjusting blocks 19 are fixedly connected to the top of the adjusting plate 18. A slot 20 adapted to the adjusting groove is opened inside the square frame 16. A telescopic rod 21 is fixedly connected to the bottom of the adjusting plate 18. The end of the telescopic rod 21 away from the adjusting plate 18 is fixedly connected to the inner wall of the central shell 2. A stabilizing spring 22 is sleeved on the surface of the telescopic rod 21. One end of the stabilizing spring 22 is fixedly connected to the inner wall of the central shell 2, and the other end of the stabilizing spring 22 is fixedly connected to the adjusting plate 18. The stabilizing spring 22 is in a compressed state as shown in the figure. The stabilizing spring 22 provides the tendency for the adjusting plate 18 to move inside the central shell 2, so that the adjusting blocks 19 will be stably inserted into their corresponding slots 20. The centrifugal force generated by the central shell 2 during rotation also tends to drive the stabilizing spring 22 to extend. Therefore, the rotational force of the central shell 2 will not cause the adjusting blocks 19 to disengage from the slots 20.

[0026] In use, this technical solution is used in conjunction with the existing winding and unwinding mechanism. This technical solution is responsible for the film cutting. The slitting motor 7 operates, driving the central shell 2 to rotate via the drive shaft 8, drive disk 9, and drive rod 10. The central shell 2 then drives the slitting blade 3 to rotate via the square frame 16. The slitting blade 3 cuts the film. When it is necessary to adjust the cutting distance between two adjacent slitting blades 3, a hand is inserted through the opening on the rear side of the central shell 2, and the adjusting plate 18 is turned. The telescopic rod 21 and the stabilizing spring 22 are compressed, and the adjusting plate 18 drives the adjusting block 19 to move. The adjusting block 19 moves into the central shell 2, thus disengaging from the slot 20 on the square frame 16. This allows the square frame 16 to slide on the surface of the central shell 2. After adjustment, release the adjusting plate 18. The stabilizing spring 22 will drive the adjusting block 19 to move through the adjusting plate 18. The new adjusting block 19 will be inserted into the slot 20. When the slitting blade 3 needs to be disassembled, pull the limiting rod 15 upward through the pull plate 24. The tension spring 25 will extend, and the limiting rod 15 will disengage from the track 12, causing the moving plate 6 to move to the right. The moving plate 6 will drive the slider 13 to disengage from the surface of the track 12. Then repeat the above process of adjusting the position of the slitting blade 3. When the adjusting block 19 disengages from the slot 20, the square frame 16 will slide on the surface of the central shell 2, and the slitting blade 3 can be disassembled from the surface of the central shell 2.
