[0024] Working principle: First, the self-adhesive composite film is placed flat at the starting end of the first conveyor belt 5. The device is started, and the rotating rollers 4 and 8 drive the conveyor belts 5 and 9 to run synchronously, so that the composite film is conveyed to the cutting area at a uniform speed. When the composite film reaches the top of the cutting area, the hydraulic pump 16 is started, and the hydraulic rod 17 drives the cutting blade 18 to cut downwards along the mating groove 14. After completion, the hydraulic rod 17 drives the cutting blade 18 to return to its original position. At the same time, the mating groove 14 assists the cutting blade 18 to return to its initial state more quickly. The cut composite film leaves the cutting area under the conveyor belt and can be collected at the end.
