Description

Technical Field

[0001] The utility model belongs to the technical field of film production, in particular to a film production trimming machine. Background Art

[0002] Film production trimming machine is a device used to trim the edges of films. It removes excess parts on both sides of the film through a precise cutting mechanism to ensure that the edges of the film are flat and smooth.

[0003] When using the existing film production trimming machine, the circular cutter is usually driven to cut and trim the two ends of the film. Since films of different widths are produced, the circular cutter needs to be disassembled in advance when trimming, and then the circular cutter needs to be moved to a suitable position and fixed. This method is not easy to quickly adjust the position of the circular cutter, resulting in complicated operation and low efficiency when the cutter position needs to be adjusted. Therefore, we propose a film production trimming machine. Utility Model Content

[0004] The purpose of the utility model is to provide a film production trimming machine, which provides a fixed frame, specifically a second starting motor to drive the bidirectional threaded rod to rotate. At this time, the two internal thread moving blocks will move closer to or away from each other, and the fixed frame will move together. The fixed frame drives the circular cutter to slide on the rotating rod, thereby adjusting the positions of the two circular cutters at the same time to meet the trimming requirements of different widths. There is no need to disassemble the circular cutter for adjustment, which reduces the operation steps and improves the adjustment efficiency. It solves the problem that the existing trimming machine needs to disassemble the circular cutter in advance when trimming films of different widths, and then move the circular cutter to a suitable position for fixing, which leads to complicated operation and low efficiency.
