Description

Technical Field

[0001] The utility model belongs to the technical field of liquid crystal film unwinding, in particular to an unwinding device for composite liquid crystal film processing. Background Art

[0002] In the production and processing of composite liquid crystal film, each process is inseparable from the unwinding device, which needs to be used for winding and unwinding. At present, the unwinding device of the composite liquid crystal film winds up the composite liquid crystal film in a naked manner. At this time, the fine gray particles on the surface of the composite liquid crystal film will scratch its surface. Small scratches require subsequent rework. If the scratch area is too large, the composite liquid crystal film will be classified as a defective product.

[0003] In the prior art, a Chinese patent with a reference number of CN 218909478 U discloses a reeling device for processing a quantum dot composite liquid crystal film, including a quantum composite liquid crystal film reeling machine and a protective upper film component, wherein the quantum composite liquid crystal film reeling machine and the protective upper film component are installed together, and two protective upper film components are installed in total, and the protective upper film components are correspondingly installed at the two sides of the quantum composite liquid crystal film reeling machine, and the quantum composite liquid crystal film is rolled up on the quantum composite liquid crystal film reeling machine. The utility model protects the quantum dot composite liquid crystal film by an attached protective film, so as to prevent the dust particles on the surface of the quantum dot composite liquid crystal film from scratching the surface of the quantum dot composite liquid crystal film after the quantum dot composite liquid crystal film is rolled up, thereby reducing the subsequent rework rate, and in addition, preventing large-area scratches on the whole, which would cause the whole to become a defective product.

[0004] The comparative document provides an unwinding device for processing quantum dot composite liquid crystal film, but the above patent uses glue on the bonding protrusions to adhere the protective film to the outer wall of the quantum dot composite liquid crystal film when protecting the quantum dot composite liquid crystal film. Due to the presence of glue, the outer wall of the quantum dot composite liquid crystal film will be adhered to the glue when it is unrolled, causing problems that are difficult to clean later.

[0005] Therefore, a reeling device for composite liquid crystal film processing is proposed. Utility Model Content

[0024] It should be noted that, since the existing unwinding device for processing quantum dot composite liquid crystal films utilizes the glue on the adhesive protrusions to achieve the adhesion of the protective film to the outer wall of the quantum dot composite liquid crystal film when protecting the quantum dot composite liquid crystal film, the presence of glue will cause the outer wall of the quantum dot composite liquid crystal film to adhere to the glue when it is unwound, resulting in subsequent difficulties in cleaning. This embodiment guides, conveys, presses and winds the composite liquid crystal film 17 and the protective film 18 to achieve the protection film 18 being adhered to the outer wall of the composite liquid crystal film 17 for winding, thereby protecting the composite liquid crystal film 17 through the protective film 18. When unwinding, it is only necessary to rewind the protective film 18. The outer wall of the composite liquid crystal film 17 will not absorb impurities such as particles and glue, and the composite liquid crystal film 17 can be conveniently processed.

[0025] Specifically, in the present embodiment, the present scheme mainly comprises a composite liquid crystal film unwinding roller 7 and a protective film unwinding roller 10. When the composite liquid crystal film 17 is unwound, the composite liquid crystal film 17 is unwound and sequentially passes through two third conveying rollers 13 and two first conveying rollers 8 and then is wound on the outer side wall of the composite liquid crystal film unwinding roller 7. The protective film 18 is unwound and sequentially passes through two second conveying rollers 12 and two first conveying rollers 8 and then is wound on the outer side wall of the composite liquid crystal film unwinding roller 7. The composite liquid crystal film 17 and the protective film 18 overlap between the two first conveying rollers 8. The two first conveying rollers 8 press the composite liquid crystal film 17 and the protective film 18 tightly. The first motor 6 outputs the composite liquid crystal film 17 and the protective film 18 through one side thereof. The end drives the composite liquid crystal film take-up and unwinding roller 7 to rotate, and the composite liquid crystal film take-up and unwinding roller 7 winds up the compressed composite liquid crystal film 17 and the protective film 18 together, and the protective film 18 is attached to the outer side of the composite liquid crystal film 17 to protect the composite liquid crystal film 17. When the composite liquid crystal film 17 and the protective film 18 on the composite liquid crystal film take-up and unwinding roller 7 are gradually wound and thickened, the hydraulic cylinder 14 drives the lifting frame 15 to move upward through the output end on one side thereof, and the pressure roller 16 on the lifting frame 15 moves upward synchronously, and the spacing between the pressure roller 16 and the composite liquid crystal film take-up and unwinding roller 7 becomes larger, which provides space for the winding of the composite liquid crystal film 17 and the protective film 18, and can also ensure the tightness of the composite liquid crystal film 17 and the protective film 18 after winding.
