[0025] By placing the cutting edge of the optical film between the two pressure plates 3, and placing the rubber strip on the upper and lower ends of the cutting edge of the optical film, and then driving the main gear 9, the sub-gear 10 and the bidirectional screw 7 to rotate through the operation of the first forward and reverse motor 8, the bidirectional screw 7 will drive the two push plates 6 to approach each other, so that the push plate 6 will push the synchronization rod 5, the synchronization plate 4, the guide rod 12, the pressure plate 3 and the pressure roller 11 into the inner edge sealing frame 2, and then the rubber strip on the cutting edge of the optical film is pressed by the pressure roller 11 on the pressure plate 3, which is conducive to regularly fitting the rubber strip on the cutting edge of the optical film.
