Description

Technical Field

[0001] This utility model relates to the field of BOPP film technology, specifically to a trimming machine for BOPP film production. Background Technology

[0002] BOPP film is a type of biaxially oriented polypropylene film with advantages such as high mechanical strength, good dimensional stability, light weight, non-toxicity, moisture resistance, and good sealing performance. It is widely used in printing, bag making, and lamination. Common types of BOPP film include ordinary type, heat-sealable type, cigarette packaging film, pearlescent film, metallized film, and matte film.

[0003] However, due to its strong tensile properties, existing BOPP film often produces some sections that stick together after being cut during trimming. If this is not addressed, these stuck sections will pull together the waste BOPP film during transport, causing the BOPP film to get stuck on the roller bearings and jam the machine.

[0004] Therefore, in order to solve the above problems, a trimming machine for BOPP film production is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a trimming machine for BOPP film production, in order to solve the problem mentioned in the background art that existing BOPP films, due to their strong tensile properties, always have some parts that stick together after being cut during trimming. If these parts are not treated, they will carry the connected waste BOPP films along with them, causing the BOPP films to get stuck on the roller bearings and jam the machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trimming machine for BOPP film production, comprising: a support structure, a limiting structure, and a trimming structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a threaded rod, a blade, a slot, a first limiting rod, and a second roller. The threaded rod drives the blade to move left and right to adjust the distance between the blades, which makes the blade more flexible in cutting BOPP films of different widths.

[0015] 2. This utility model comprises a second drive motor, a first rotating disk, a third rotating disk, a second rotating disk, a first belt, a second belt, a third roller, and a fourth roller. The second drive motor rotates the second rotating disk, which in turn drives the first and third rotating disks to rotate via the first and second belts. This, in turn, causes the second and third rotating disks to rotate the inner connected third and fourth rollers, pulling the edges of the BOPP film. This prevents the BOPP film from flowing back during trimming due to unclean cutting. Attached Figure Description
