Start the rotating motor 407, and the rotating motor 407 drives the rubber wheel 405 to rotate. Then, through the extrusion between the rubber wheel 405 and the conveyor belt 410, the zipper can be conveyed. At the same time, the driving motor 201 rotates to drive the cam 202 to rotate. Then, under the rotation and contact of the cam 202 and the elastic force of the spring 304, the lifting column 10 slides up and down in the through groove 9, driving the lifting plate 302 to move up and down on the limiting column 301. Finally, the cutting knife 303 can be driven to cut the zipper. The cut zippers fall from the blanking port 11 into the collection box.
