Description

Technical Field

[0001] The utility model relates to the technical field of strip-type film processing, in particular to a strip-type film cutting device. Background Art

[0002] A film is a material widely used to protect the surface of an object. It is designed to be temporarily attached to an object to prevent it from being damaged by scratches, dust, stains, and moisture. Taking the case as an example, the film is attached to the surface of the case through a strip to provide protection for its surface.

[0003] During the production process, the mold film is first squeezed into a thin film by an extruder, and then cooled and trimmed by a roller press to ensure its flatness. However, due to the different sizes and shapes of the casing, the mold film usually needs to be precisely cut to meet different needs.

[0004] The traditional film cutting method usually uses a single knife cutting method, first measuring one end of the film and cutting it, then moving the cut end to the cutting platform and measuring and cutting it again. This method is not only cumbersome to operate, but also prone to deviations during manual measurement, affecting the quality of the cut product. In addition, the single knife cutting method requires multiple reciprocating lifts and drops, which is inefficient.

[0005] More importantly, due to the characteristics of the material itself, the mold film is prone to wrinkles or loosening during the cutting process, resulting in an uneven cut end surface, further reducing the quality of the finished mold film. Utility Model Content

[0056] The cutting steps of the cutting device for the strip film of the utility model are as follows:

[0057] The steps of placing the strip film on the processing platform 10 are as follows: the strip film passes through the gap between a set of limiting baffles 20 and the processing platform 10, is laid flat on the processing platform 10, and is limited by another set of limiting baffles 20. Thus, the strip film is laid.

[0058] The steps of cutting the strip film are as follows: the fixed frame 501 is rotated downward, and the driving shaft 401 is driven to rotate during the rotation of the fixed frame 501, and the driving shaft 401 drives the push rod 402 and the outer baffle 302 to contact and connect, thereby driving the movable bracket 303 to rotate, and the movable bracket 303 is driven to move the flat pressing mechanism 304 on the processing platform 10 during the rotation. And the driven shaft 503 rotates with the fixed frame 501, and the driven shaft 503 moves in the limit groove 603, and the driven shaft 503 and the outer sleeve 601 are separated, and the reset component 604 drives the outer sleeve 601 to rotate, and the pressing plate 602 is pressed on the processing platform 10 to press and fix the front end of the strip film. And when the fixed frame 501 rotates downward, the pressing roller 3044 in the flat pressing mechanism 304 moves, and the strip film is flat on the processing platform 10. Then, during the cutting process of the cutting knife 502, it is ensured that the strip film has no wrinkles, the cutting end face is smooth, and the finished product has high quality.
