Description

Technical Field

[0001] This utility model relates to the field of optical protective film slitting technology, and in particular to a film slitting machine for producing optical protective films. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide sheets of paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable manufacturing, and printing and packaging machinery. Slitting machines are primarily used for cutting non-woven fabrics, mica tape, paper, insulating materials, and various films, and are particularly suitable for cutting narrow strips (non-woven fabrics, paper, insulating materials, mica tape, films, etc.). Optical protective film is one of the simplest optical thin films, a smooth, isotropic, homogeneous dielectric thin layer. In this case, the optical properties of the optical thin film can be studied using the theory of light interference. In the production of optical protective film, wide films are usually first made into rolls as semi-finished products, and then slitting machines cut the wide films into appropriate sizes.

[0003] Existing film slitting machines for optical protective films use slitting blades to cut the films. However, the blades are in a relatively fixed position, making it difficult to adjust the positions of multiple blades evenly and at equal intervals. This also makes it difficult to cut wider optical protective films into multiple narrower ones at equal intervals. Furthermore, the blades wear down after prolonged use, causing a significant pause in the cutting process when replacing them. This prevents the machines from quickly replacing the blades and minimizing the downtime.

[0004] Therefore, a film slitting machine for producing optical protective films is proposed to solve the problems mentioned above. Utility Model Content
