Description

Technical Field

[0001] This utility model relates to the field of thin film cutting technology, specifically a semi-automatic film roll cutting mechanism. Background Technology

[0002] A thin film is a thin, soft, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is a two-dimensional material formed by the deposition of atoms, molecules, or ions on the surface of a substrate. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in industries such as electronics, machinery, and printing.

[0003] The patent CN222475648U discloses a semi-automatic winding equipment for lithium battery production. This patent discloses a convenient cutting technology solution, which solves the problem that existing lithium battery separator winding equipment does not have the function of automatically cutting lithium battery separators.

The electric push rod 5 is activated. The output end of the electric push rod 5 drives the connecting roller 6 to move downward, so that the cutter 11 and the film are bonded. The connecting roller 6 is supported by the sliding connection between the sliding block 18 and the sliding groove 9, thereby improving the stability of the connecting roller 6.

[0037] It should be noted that the electric actuator 5 is a conventional device known in the prior art, and its specific structure and working principle will not be described in detail here.

The moving plate 24 and the limiting block 25 are in contact, and the limiting block 25 is fixed. The film is wound up by the winding roller 3 and supported by the... Roller 29 and bonding roller 7 support the film, which is located between connecting roller 6 and bonding roller 7. The electric push rod 5 is activated, and its output end drives the connecting roller 6 downward, so that the cutter 11 and the film are bonded. The connecting roller 6 is supported by the sliding block 18 and the sliding groove 9, which improves the stability of the connecting roller 6. The drive motor 17 is activated, and its output shaft drives the first screw 16 to rotate. Through the threaded connection between the first screw 16 and the linkage plate 14 and the sliding connection between the linkage plate 14 and the linkage groove 15, the first screw 16 drives the cutter 11 to move through the linkage plate 14, so that the cutter 11 moves back and forth to cut the film.
