Technical Field
[0001] This utility model relates to the field of packaging film processing technology, specifically to a strip cutting device for packaging film processing. Background Technology
[0002] A film is a thin, soft, transparent sheet made of plastic, adhesive, rubber, or other materials. Scientifically, a film is a two-dimensional material formed by the deposition of atoms, molecules, or ions on the surface of a substrate. Films are widely used in industries such as electronics, machinery, and printing. Packaging is a common type of film, and packaging films need to be cut into strips during processing due to packaging requirements.
[0003] However, current slitting devices are still not ideal in operation because after each cut, the film and the slitting device need to be manually adjusted to ensure the next cut, which is very inconvenient and needs to be optimized.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: a strip-cutting device for packaging film processing, including a workbench 1, with symmetrically distributed fixing blocks 11 fixedly installed at the top of the workbench 1, a screw 12 rotatably installed at the opposite end of the fixing blocks 11, an L-shaped frame 13 threaded onto the outer side of the screw 12, a support shaft 14 installed at one end of the L-shaped frame 13, a film roll 15 installed on the outer side of the support shaft 14, a motor 16 fixedly installed on the outer side of one fixing block 11, the drive end of the motor 16 fixedly connected to one end of the screw 12, a sliding groove 17 opened at the top of the workbench 1, a movable plate 18 slidably installed inside the sliding groove 17, a strip-cutting device 19 fixedly installed at one end of the movable plate 18, a support plate 20 fixedly installed on one side of the top of the workbench 1, an electric push rod 21 fixedly installed at one end of the support plate 20, and one end of the electric push rod 21 fixedly connected to one end of the movable plate 18.
[0020] One end of the L-shaped frame 13 is fixedly installed with symmetrically distributed connecting blocks 22. A locking post 23 is fixedly installed on the top of the connecting block 22. A rotating block 24 is rotatably installed on the outside of the locking post 23. A retaining ring 25 is fixedly connected to the top of the rotating block 24. One end of the retaining ring 25 is movably engaged with the outside of the support shaft 14. A lower fixing block 26 is fixedly installed on one end of the connecting block 22. An upper fixing block 27 is fixedly installed on one end of the retaining ring 25. A bolt 28 is threadedly installed on one end of the lower fixing block 26. One end of the bolt 28 is threadedly connected to the upper fixing block 27.
[0021] By adopting the above technical solution, the snap ring 25 is fastened to the support shaft 14 to facilitate the positioning of the film roll 15. The bolt 28 is not fixed to the upper block 27, so the snap ring 25 is rotated to disengage from the support shaft 14. This makes it convenient to collect the film roll 15 after it has been cut and to assemble the film roll 15 ready to be cut. The structure is flexible and makes the film roll 15 more stable during processing.
[0022] The top of the workbench 1 is fixedly equipped with symmetrically distributed N-shaped plates 29, and one end of the L-shaped frame 13 is slidably sleeved on the outside of the N-shaped plates 29.
[0023] By adopting the above technical solution, the L-shaped frame 13 is supported and reinforced by setting the N-shaped plate 29.
[0024] Symmetrically distributed limiting pieces 30 are fixedly installed on the outer side of the locking post 23, and one end of the limiting piece 30 is in contact with the rotating block 24.
[0025] By adopting the above technical solution, the movement of the rotating block 24 and the retaining ring 25 is limited by setting the limiting piece 30.
[0026] The bottom of the workbench 1 is fixedly equipped with an array of moving wheels 31.
[0027] By adopting the above technical solution, the worktable 1 can be moved by setting the moving wheels 31.
[0028] A handle 32 is fixedly installed on the side of the workbench 1.
[0029] By adopting the above technical solution, the handle 32 makes it easy to control the direction of movement of the moving wheel 31.
[0030] Working principle: First, when the film roll 15 needs to be cut into strips, the motor 16 is controlled to rotate the screw 12. The rotation of the screw 12 drives the L-shaped frame 13 to move horizontally. The N-shaped plate 29 guides and supports the L-shaped frame 13. The L-shaped frame 13 then drives the support shaft 14 and the film roll 15 to contact the cutting device 19 and cut strips. Then, the film roll 15 is controlled to reset. Then, the electric push rod 21 pushes the moving plate 18 to slide in the slide groove 17 to adjust the position of the cutting device 19 and cut strips again, thus realizing continuous cutting processing, which is more convenient and efficient and improves processing efficiency. During the processing, the film roll 15 is fastened to the support shaft 14 by the retaining ring 25 to facilitate the limiting of the film roll 15. The bolt 28 is not fixed to the upper fixing block 27, so the retaining ring 25 is rotated to disengage from the support shaft 14, which facilitates the collection of the cut film roll 15 and the assembly of the film roll 15 ready for cutting. The flexible structure makes the film roll 15 more stable during processing.
[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
