Detailed Description

The invention will be further explained with reference to the accompanying drawings 1-4:

a cylinder 1 and a guide plate 5 are fixed on a bottom plate 11, a guide groove 14a extending along a straight line and a guide groove b15 with a bending part are arranged on the guide plate 5, the cylinder 1 is connected with a driving block 16 positioned in the guide groove a14, a driven block 17 is connected in a sliding way in a guide groove b15, the driving block 16 is connected with a scissor leg a7, a scissor leg b10 is rotatably connected with the scissor leg a7 through a rotating shaft 9, a compression spring 6 is sleeved on the rotating shaft 9, two ends of the compression spring 6 are respectively contacted with a scissor leg a7 and a fastening nut b13, the fastening nut b13 is positioned at the top of the rotating shaft 9, the end of the scissor leg b10 is connected with the driven block 17, the scissor leg a7 and the scissor leg b10 are both movably arranged at the lower part of the guide plate 5, the end of the scissor leg a7 is connected with a shearing edge a8, and the end of the scissor leg b10 is connected with a shearing edge b 18. The cylinder 1 is fixed to the base plate 11 by a fixing plate 19. The output end of the cylinder 1 is connected with a sliding support 4, the bottom of the sliding support 4 is connected with a driving block 16, and the sliding support 4 is connected on a guide plate 5 in a sliding mode. The sliding support 4 is fixedly connected with the output end of the cylinder 1 through nuts a2 and limiting nuts 3 on two sides. The bottom plate 11 is connected to the mask rope processing machine through a connecting block 12, and the bottom plate 11 is located on the side of a moving path of the mask rope.

The mask rope is moved and conveyed in the mask rope processing machine, moves for a preset distance, namely a preset length, the air cylinder 1 drives the shear blade a8 and the shear blade b18 to extend to a moving path of the mask rope and cut, the mask rope returns after being cut, and the process is circulated to cut the mask rope with a fixed length. The specific cutting action is as follows: the air cylinder 1 drives the driving block 16 to linearly move leftwards along the guide groove a14 (as shown in fig. 2), the driving block 16 drives the scissor leg a7 to move leftwards, the scissor leg a7 drives the scissor leg b10 to move leftwards, the scissor leg b10 drives the driven block 17 to move along the guide groove b15, when the driven block passes through the bending part of the guide groove b15, the driven block 17 changes the direction, the scissor leg b10 rotates around the rotating shaft 9, the scissor edge b18 is closed to the scissor edge a8, and the scissor edge a8 and the scissor edge b18 are pressed tightly in the longitudinal direction under the action of the compression spring 6, so that the mask rope is cut.
