[0002] Quantum dot film, as a novel nano-luminescent material, is playing an increasingly important role in the field of electronic displays. It is mainly produced into large-size rolls through a coating process, and then needs to be slit and rolled into smaller rolls before it can be used in subsequent die-cutting processes. Finally, it becomes a sheet film used in electronic devices. This film is widely used in the high-end display market such as laptops and TVs, and can significantly improve the color gamut and color performance of the display, making the picture more vivid and realistic, and bringing users a better visual experience.

[0003] In existing technologies, adjusting the position of the slitting blade is inconvenient and difficult to adapt to the slitting requirements of quantum dot films of different widths; adjusting the slitting blade individually or synchronously is complex and affects processing efficiency; and the slitting blade is not securely fixed, which may affect slitting accuracy and stability.

[0029] Please see Figures 1-5A slitting and winding structure for a quantum dot film includes a winding roller 1, with support shafts 2 on both sides of the winding roller 1. A drive device is connected to one end of each support shaft 2. A moving groove 3 is provided inside the winding roller 1, and a partition 4 is provided inside the moving groove 3. A threaded sleeve 5 is rotatably provided on one side of the partition 4, and a threaded rod 6 is rotatably provided on the other side. Moving blocks 7 are threadedly connected to both the threaded sleeve 5 and the threaded rod 6. A slitting blade 8 is provided on the moving blocks 7. One end of the threaded sleeve 5 extends out of the support shaft 2 and is fixedly provided with a first handle 9. One end of the threaded rod 6 extends out of the threaded sleeve 5 and the support shaft 2 and is fixedly provided with a second handle 10. A locking device is provided between the support shaft 2 and the first handle 9, and a limiting device is provided between the first handle 9 and the second handle 10.

[0030] In this embodiment, during use, the slitting blade 8 is mounted on the moving block 7. The thread pitch on the threaded sleeve 5 and the threaded rod 6 is the same. By rotating the first handle 9, the threaded sleeve 5 is rotated, adjusting the position of the slitting blade 8 on the threaded sleeve 5. By rotating the second handle 10, the threaded rod 6 is rotated, thereby adjusting the position of the moving block 7 and the slitting blade 8 on the threaded rod 6. This improves the flexibility and practicality of adjusting the slitting blade 8 on the slitting roller. The locking device connects and fixes the support shaft 2, the first handle 9, and the second handle 10 to prevent the slitting blade 8 from shifting during slitting, thus improving the accuracy and stability of slitting. The drive device adopts existing technologies such as motors and transmission devices to drive the slitting roller to rotate. After the quantum dot film is slitted by the slitting blade 8, it is wound up.

[0031] Please see Figures 2-5 As one embodiment of the locking device and limiting device: the locking device includes a locking rod 11, which is slidably disposed within the support shaft 2. A locking hole 12, cooperating with the locking rod 11, is provided circumferentially on the first handle 9. A locking groove 13 is provided within the support shaft 2, and a sliding groove 14 is provided within the locking groove 13. A locking plate 15 is provided within the locking groove 13 on the locking rod 11. A sliding block 16, cooperating with the sliding groove 14, is provided on the locking plate 15. A turning groove 17 is provided at the bottom of the sliding groove 14. A support groove 18 is provided on one side of the locking groove 13, and the support groove 18 engages with the locking... A telescopic rod 19 is provided between the plates 15. A compression spring 20 is wound around the outside of the telescopic rod 19. One end of the locking rod 11 is provided with a slot 21. The limiting device includes a limiting sleeve 22. The limiting sleeve 22 is circumferentially fixed on the first handle 9. A limiting rod 23 that cooperates with the limiting sleeve 22 is slidably provided on the second handle 10. A fixed sleeve 24 is provided on the second handle 10. A limiting plate 25 is fixedly provided inside the fixed sleeve 24. A limiting spring 26 is provided between the limiting plate 25 and the fixed sleeve 24. A limiting handle 27 is provided at one end of the limiting rod 23.

[0032] More specifically, when the second handle 10 is rotated alone, the first handle 9 is fixed to the support shaft 2 via the locking device. Pulling the limiting handle 27 outward causes the limiting rod 23 to move outward and disengage from the limiting sleeve 22. Simultaneously, within the fixed sleeve 24, the limiting plate 25 is compressed and the limiting spring 26 is compressed. Subsequently, the limiting rod 23 drives the second handle 10 to rotate, which in turn drives the threaded rod 6 to rotate. Adjusting the position of the moving block 7 and the cutting blade 8 on the threaded rod 6 releases the limiting handle 27. The limiting rod 23 extends into the limiting sleeve 22, fixing the position of the second handle 10. When the first handle 9 and the second handle 10 are rotated simultaneously, a screwdriver is inserted into the slot 21 to press the locking rod 11. This causes the locking rod 11 to drive the sliding block 16 of the locking plate 15 to slide along the sliding groove 14, compressing the telescopic rod 19 and the compression spring 20. When the sliding block 16 moves into the turning groove 17, the screwdriver drives the locking rod 11 to rotate. Rotation causes the sliding block 16 to extend into the steering groove 17, limiting the position of the sliding block 16 and the locking rod 11. The first handle 9 and the second handle 10 are fixed by the limiting device. Rotating the first handle 9 and the second handle 10 simultaneously achieves the effect of keeping the distance between the two slitting blades 8 constant and moving the two slitting blades 8 in the same direction. Then, continue to rotate the locking rod 11 so that the sliding block 16 is aligned with the sliding groove 14. Under the elastic force of the compression spring 20, the locking plate 15 drives the locking rod 11 to extend into the locking hole 12, fixing the position of the first handle 9 and the second handle 10. When only the first handle 9 needs to be rotated, the locking device is unlocked and the limiting device is opened. When the limiting device is opened, one hand fixes the position of the limiting handle 27 and the second handle 10, and the other hand rotates the first handle 9. This allows only the position of the moving block 7 on the threaded sleeve 5 and the slitting blade 8 to be adjusted. The adjustment of the position of the slitting blade 8 is simple, convenient and highly practical.

[0033] In summary, during use or operation of the overall equipment: When in use, the slitting blade 8 is mounted on the moving block 7. The thread pitch on the threaded sleeve 5 and the threaded rod 6 is the same. By rotating the first handle 9, the threaded sleeve 5 is rotated, adjusting the position of the slitting blade 8 on the threaded sleeve 5. By rotating the second handle 10, the threaded rod 6 is rotated, thereby adjusting the position of the moving block 7 and the slitting blade 8 on the threaded rod 6. This improves the flexibility and practicality of adjusting the slitting blade 8 on the slitting roller. A locking device connects and fixes the support shaft 2, the first handle 9, and the second handle 10, preventing the slitting blade 8 from shifting during slitting, thus improving the accuracy and stability of slitting. The drive device uses existing technologies such as motors and transmission devices to drive the slitting roller to rotate. After the quantum dot film is slitted by the slitting blade 8, it is then wound up.

[0034] When the second handle 10 is rotated alone, the first handle 9 is fixed to the support shaft 2 via the locking device. Pulling the limiting handle 27 outward causes the limiting rod 23 to move outward and disengage from the limiting sleeve 22. Simultaneously, the limiting plate 25 is compressed and the limiting spring 26 is compressed within the fixed sleeve 24. Subsequently, the second handle 10 is rotated via the limiting rod 23, which in turn causes the threaded rod 6 to rotate. Adjusting the position of the moving block 7 and the cutting blade 8 on the threaded rod 6 releases the limiting handle 27. The limiting rod 23 extends into the limiting sleeve 22, fixing the position of the second handle 10. When the first handle 9 and the second handle 10 are rotated simultaneously, a screwdriver is inserted into the slot 21 to press the locking rod 11. This causes the locking rod 11 to drive the sliding block 16 of the locking plate 15 to slide along the sliding groove 14, compressing the telescopic rod 19 and the compression spring 20. When the sliding block 16 moves into the turning groove 17, the locking rod 11 is rotated via the screwdriver. This allows the sliding block 16 to extend into the turning groove 17, limiting the positions of the sliding block 16 and the locking rod 11. The first handle 9 and the second handle 10 are fixed by the limiting device. By rotating the first handle 9 and the second handle 10 simultaneously, the distance between the two slitting blades 8 is kept constant, and the two slitting blades 8 move in the same direction. Then, the locking rod 11 is rotated so that the sliding block 16 is aligned with the sliding groove 14. Under the elastic force of the compression spring 20, the locking plate 15 drives the locking rod 11 to extend into the locking hole 12, fixing the positions of the first handle 9 and the second handle 10. When only the first handle 9 needs to be rotated, the locking device is unlocked and the limiting device is opened. When the limiting device is opened, one hand fixes the position of the limiting handle 27 and the second handle 10, and the other hand rotates the first handle 9. This allows only the position of the moving block 7 and the slitting blade 8 on the threaded sleeve 5 to be adjusted. The adjustment of the position of the slitting blade 8 is simple, convenient, and highly practical.
