Technical Field
[0001] The utility model belongs to the technical field of release film processing, and particularly relates to a release film slitting device. Background Art
[0002] A release film, also known as an isolation film or a demolding film, is a thin film material with a special coating on its surface, mainly used to separate formed composite materials, tapes, labels, etc. from molds or other surfaces during industrial production. The coating of this thin film usually has a low surface energy or specific chemical properties, making it difficult for adhesives, resins, etc. to adhere. Thus, after the product manufacturing is completed, it can be easily detached from the mold without leaving any residues, ensuring the surface quality of the product and the reuse of the mold. Release films are widely used in industries such as electronics, printing, die-cutting, medical, and construction.
[0003] In the existing traditional release film slitting technology, during the operation of the slitting device, it is usually necessary to unwind the release film that has been wound up. However, in this step, the tightly wound release film often shows a dislocation phenomenon when being unwound. This problem leads to the incompleteness of the slitting process, thereby affecting production efficiency and product quality. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a release film slitting device to solve the problem that in the existing traditional release film slitting technology, during the operation of the slitting device, it is usually necessary to unwind the release film that has been wound up. However, in this step, the tightly wound release film often shows a dislocation phenomenon when being unwound.

[0013] 1. By means of structures such as the limiting plate provided in the present utility model, when the release film is unrolled, the device is installed at the feeding end of the slitter. The handle is rotated, and the handle drives the driving gear to rotate through the rotating shaft, so that the driven gear and the adjusting rod rotate.

However, in this step, the tightly wound release film often shows a dislocation phenomenon when it is released, which leads to the incompleteness of the slitting process, thereby affecting the production efficiency and product quality.
[0014] 2. By means of the telescopic rod structure and the spring structure provided in the present utility model, when the limiting plate squeezes the release film towards the middle, a buffering effect is achieved through the telescopic rod structure and the spring structure, thereby preventing the release film from being squeezed and wrinkled directly, which may lead to the problem of deformation during slitting.

Specific implementation manners
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-6, the present utility model provides a technical solution: a release film slitting device, which includes a main body frame 1. An adjustment groove 2 is formed on the inner surface of the main body frame 1. An adjustment rod 3 is rotatably connected inside the adjustment groove 2. Both ends of the surface of the adjustment rod 3 are threadedly connected with adjustment blocks 8. The middle part of the side surface of the adjustment rod 3 is fixedly connected with a driven gear 4. A rotating shaft 6 is rotatably connected through the upper end inside the main body frame 1. The lower end of the side surface of the rotating shaft 6 is fixedly connected with a driving gear 7. The driving gear 7 and the driven gear 4 are meshed with each other. An installation groove 9 is formed at the lower end of the inner surface of the adjustment block 8. A telescopic rod structure 10 is installed on the inner surface of the installation groove 9. The output end of the telescopic rod structure 10 is installed with a limiting plate 12. By setting structures such as the limiting plate 12, when unwinding the release film, the device is installed at the feeding end of the slitter. Rotate the handle 5, and the handle 5 drives the driving gear 7 to rotate through the rotating shaft 6, so that the driven gear 4 and the adjustment rod 3 rotate. The two adjustment blocks 8 at both ends of the adjustment rod 3 slide towards the middle at the same time, thereby driving the limiting plate 12 to squeeze towards the middle. The two sides of the winding roller winding the release film are limited and blocked by the limiting plate 12, achieving the purpose of limiting the position of the release film during feeding. At the same time, the limiting plate 12 structure that can be adjusted left and right can achieve the purpose of unwinding and limiting release films of different widths, facilitating the subsequent slitting work of the slitter, and effectively avoiding the problem that in the existing traditional release film slitting technology, during the operation of the slitting device, it is usually necessary to unwind the release film that has been wound up. However, in this step, the tightly wound release film often shows a dislocation phenomenon when being unwound. This problem leads to the incompleteness of the slitting process, thereby affecting the production efficiency and product quality.
[0025] In the present utility model, preferably, the main body frame 1 is detachably installed inside the slitter through fixing bolts.
[0026] In the present utility model, preferably, the upper end of the rotating shaft 6 is fixedly connected with a handle 5.
[0027] In the present utility model, preferably, a spring structure 11 is arranged on the surface of the telescopic rod structure 10. By setting the telescopic rod structure 10 and the spring structure 11, when the limiting plate 12 squeezes the release film towards the middle, a buffering effect is achieved through the telescopic rod structure 10 and the spring structure 11, thereby preventing the release film from being squeezed to produce wrinkles due to direct extrusion, resulting in deformation during slitting.
[0028] In the present utility model, preferably, a plurality of installation holes 13 are formed on the inner surface of the limiting plate 12.
[0029] In the present utility model, preferably, an installation bolt 14 is provided inside the installation hole 13, and the limiting plate 12 is fixedly installed at the output end of the telescopic rod through the installation bolt 14. Through structures such as the installation hole 13 and the installation bolt 14, a detachable connection is achieved between the limiting plate 12 and the adjusting block 8, facilitating the purpose of limiting release films with different thicknesses.
[0030] In the present utility model, preferably, a baffle 15 is fixedly connected to the inner surface of the limiting plate 12.
[0031] The working principle and usage process of the present utility model: When using this release film slitting device, first install the device at the feeding end of the slitter and ensure its stability through fixing bolts. Then, rotate the handle 5. The handle 5 drives the rotation shaft 6 to rotate, and further drives the driving gear 7 to rotate, causing the driven gear 4 and the adjusting rod 3 to rotate accordingly. At this time, the adjusting blocks 8 at both ends of the adjusting rod 3 slide towards the middle, driving the limiting plate 12 to squeeze towards the middle, achieving the limitation and blockage of the release film winding roller. Through the buffering effect of the spring structure 11, wrinkles on the release film during the squeezing process are avoided. After the limiting plate 12 is fixed in a suitable position, the release film can be unwound. During the unwinding process, the limiting plate 12 can be adjusted left and right to adapt to release films with different widths. If it is necessary to replace release films with different thicknesses, the distance between the limiting plate 12 and the adjusting block 8 can be adjusted by removing the installation bolt 14. The presence of the baffle 15 ensures the stability of the limiting process, thereby improving the slitting efficiency and product quality of the slitter.
[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
