[0025] During operation, the papermaking mesh blanket bypasses the transition roller 2, and two pressure rollers 5 press the papermaking mesh blanket against the transition roller 2. The cutting assembly is moved on the track 7 according to the width of the papermaking mesh blanket to be cut, and the motor 3 drives the transition roller 2 to rotate to transport the papermaking mesh blanket backward. When the motor 3 drives the transition roller 2 to rotate, it drives the driving gear 8 to rotate, and the driving gear 8 engages to drive two driven gears 9. The two driven gears 9 drive the two pressure rollers 5 to rotate, and the rotation directions of the transition roller 2 and the two pressure rollers 5 are opposite, so that the papermaking mesh blanket is efficiently transported, so that the cutting assembly cuts the papermaking mesh blanket. Since the papermaking mesh blanket is tightened by the two pressure rollers 5 and the transition roller 2, the papermaking mesh blanket will not bulge when being cut, thereby improving the cutting quality.
