The high-speed cross cutter for cutting paper according to claim 1, wherein: the transverse cutter (7) comprises a blunt port (71) and an arc-shaped cutter edge (72), the blunt port (71) is positioned on two side edges of the transverse cutter (7), and the arc-shaped cutter edge (72) is fixed at the bottom of the transverse cutter (7).
10. A cutting method of a high-speed cross cutter for cutting paper according to any one of claims 1 to 9, characterized by comprising the steps of:
s1: according to production requirements, determining the length a and the width b of the paper sheets and the speed Y of the conveyor belt (311), c being the motion path of the cross-cutting knife (7) according to the formula (a + (S · Y) + b = c, and then determining the horizontal included angle X of the cross-cutting knife (7) relative to the conveyor belt mechanism (3) according to a trigonometric function, S being the time for cutting one paper sheet;
s2: determining the speed for cutting one paper sheet by the cross cutter (7) according to a trigonometric function, wherein the time S in the steps S1 and S2 can be changed according to production requirements, and the longer the time is, the slower the movement speed of the cross cutter (7) is, the faster the speed is, the shorter the time S is, and the self-regulation and control can be carried out according to production requirements;
s3: adjusting the position of the conveying belt (3) through the angle adjusting device (6) according to the included angle X obtained in the step S1, so that the horizontal included angle of the transverse cutter (7) relative to the conveying belt mechanism (3) is X;
s4: the position of the transverse cutter (7) above the conveyer belt mechanism (3) is adjusted by the lifting cylinder and the single cylinder (11), so that the transverse cutter (7) can cut paper;
s5: the rolled paper is put into a traction mechanism (5), the traction mechanism (5) sends the paper to a conveying belt mechanism (3) to move, and then a transverse cutter (7) reciprocates on the paper to cut the paper.
