s5, when the razor is used for cutting, the upper cutter (22) is replaced by the razor frame (8), the razor frame (8) is clamped by the upper cutter clamping mechanism (25) through a PLC program instruction, the upper cutter arranging electric cylinder (21) is combined with the upper cutter servo motor (24) to drive the upper moving frame (27) to drive the upper cutter clamping mechanism (25) and the razor frame (8) to move, and meanwhile, the razor frame (8) is accurately placed to a program appointed position through sensing of the upper cutter sensor (26);

s6, after the razor frame (8) is placed, the razor frame (8) is fixed by automatic inflation of the upper cutter air expansion shaft (23), and finally the swing servo motor (42) drives the gear (44) to swing and rotate the swing arm (47) to a set position to realize cutting.
