Description

Technical Field

[0001] This utility model relates to the field of protective film cutting technology, specifically to a self-adhesive protective film cutting device. Background Technology

[0002] Protective films can be classified into coated films and self-adhesive films according to their properties. Self-adhesive film is short for self-adhesive protective film, which is used to protect fragile plastic films. Compared with coated films, self-adhesive films have many advantages, such as no residue, stable adhesion, low cost and high profit. In recent years, self-adhesive films have become the mainstream in the market.

[0003] Chinese Patent No. CN219882558U discloses a high-temperature resistant self-adhesive protective film cutting device, including a worktable. A set of mounting frames is provided on the worktable, and a protective film roll is mounted on the mounting frames. Two sets of auxiliary mounting frames are also mounted on the worktable, with a conveyor roller rotatably connected between each set of auxiliary mounting frames. An L-shaped frame is fixedly mounted on the worktable, and two electric telescopic rods are fixedly mounted on the L-shaped frame. A U-shaped lowering plate is fixedly mounted at the bottom of the output end of the electric telescopic rods, and a cutting blade is fixedly mounted at the bottom end of the lowering plate. This invention has the following advantages: the two electric telescopic rods can drive the lowering plate and the cutting blade to descend, completing the protective film cutting. Before cutting, the lowering component contacts the surface of the protective film in advance, thus ensuring that the film is flattened during cutting, ensuring a neat cut and avoiding affecting product quality.

[0004] However, the above technical solution has the following shortcomings: the spacing between the conveyor rollers is difficult to adjust; when cutting protective films of different thicknesses, the clamping force between the conveyor rollers and the protective film is difficult to adjust; when cutting thicker protective films, the clamping force of the conveyor rollers on the protective film is too large, which can easily lead to excessive compression of the protective film; when cutting thinner protective films, the clamping force between the conveyor rollers and the protective film is insufficient, and slippage can easily occur between the conveyor rollers and the protective film, causing the conveyor rollers to be unable to transport the protective film, increasing debugging and maintenance costs.
