[0029] Working principle: Before using this non-woven fabric slitting positioning device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, the staff operates the extrusion mechanism 3 to make the positioning plate 103 squeeze the non-woven fabric on the cutting table 102. At this time, the cutting knives 105 on both sides of the positioning plate 103 can quickly cut the edge of the non-woven fabric. When the non-woven fabric needs to be cut into different widths, the staff places the appropriate cutting table 102 and the positioning plate 103 on the top of the workbench 1.

At this time, the first telescopic spring 212 stretches and resets, and the tension generated by the first telescopic spring 212 can make the installation of the toothed plate 207 more stable. The design of the limit block 214 can make the rotation of the rotating rod 204 more stable. The design of the rotating block 215 can facilitate the staff to rotate the worm 206.

[0030] The rotation of the turntable 308 drives the movable rod 310 to rotate in a circular trajectory, and then the movable rod 310 pulls the push rod 309 to slide inside the bracket 101, and then the positioning plate 103 can be driven up and down by the connecting frame 104.
