[0002] Laser film generally adopts computer dot lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. From the perspective of product composition, laser film products can be roughly divided into three types: OPP laser film, PET laser film and PVC laser film. Laser packaging is a sub-industry in the packaging industry and has achieved rapid development. Compared with other products in the packaging industry, laser packaging materials not only have novel and bright appearance, but also have high-tech anti-counterfeiting functions. It is known as the most cutting-edge technology product in the world's packaging and printing industry.

[0003] After the laser film is produced, it is a whole and needs to be slit and rolled. For example, a Chinese patent with authorization announcement number CN218664621U discloses a transparent laser film slitting and rolling device, including a limiting winding plate and a use device, the use device includes an adjusting roller, a threaded slider, a threaded rod, a mounting frame, a motor, a roller shaft, a connecting sleeve, and a fastening bolt; the limiting winding plate is provided with a sliding groove, one end of the adjusting roller is movably installed with the threaded slider, the threaded slider is sleeved on the outer wall of the threaded rod, and the threaded slider is threadedly connected to the threaded rod.

[0004] Although the device realizes the slitting function, the slitting blades cannot adjust the spacing and have a narrow application range. At the same time, the surface of the laser film is not cleaned during slitting and winding, and the dust particles attached to the surface can easily damage the laser film under the squeezing force of winding. Therefore, we propose a slitting device for laser film processing to solve the above problems. Utility Model Content

[0024] Specifically, the cross-section of the vertical slide groove 4 is a cross-shaped structure, which cooperates with the slider 5 of the cross-shaped structure to ensure that the slider 5 slides linearly while preventing the slider 5 from detaching. The tool holder 10 is an L-shaped structure, and the tool holder 10 in the upper horizontal slide groove 8 and the tool holder 10 in the lower horizontal slide groove 15 are symmetrically staggered.

When in use, the laser film to be cut is placed at the position of the unwinding roller 14, and then the laser film passes through the tensioning roller 12. The tensioning roller 12 supports and tensions the laser film. The laser film then passes through the bottom of the adjusting seat 2, and the cutter 11 performs a cutting operation on the laser film.

The slitting laser film passes through the movable plates 7, passes through the tensioning roller 12, and finally is wound up by the winding roller 13. The two ends of the movable plate 7 are fixedly connected to the slider 5 by screws, and the two opposite ends of the slider 5 are fixedly connected to the spring 6 respectively.
