[0024] The plastic wire initially extruded by the extruder 2 is guided to the bottom of a pair of guide rollers 3, and then wound around a plurality of wire drawing rollers 5 in an interlaced manner in sequence, and finally wound around a winding roller 6. The rotating winding roller 6 drives a plurality of wire drawing rollers 7 to rotate, thereby winding the plastic wire attached to the winding roller 6 around the winding roller 6. The above operations complete the preliminary installation of the plastic wire.

[0025] The cutting device includes an electric telescopic rod 8 fixedly installed on the top of the support frame 4, the output end of the electric telescopic rod 8 passes through the top plate of the support frame 4 and is fixedly installed with a lifting plate 9, a cutter 10 is fixedly installed at the bottom of the lifting plate 9, and a rotating rod 11 is slidably installed on both side walls of the support frame 4, one end of the rotating rod 11 is rotatably connected to one side of the lifting plate 9, and a connecting plate 12 is fixedly installed on the other end of the rotating rod 11, a first rack 13 is fixedly installed at a position near the rotating rod 11 on one side of the support frame 4, and a first gear 14 meshing with the first rack 13 is fixedly installed at a position near the first rack 13 on the outer peripheral wall of the rotating rod 11;

Then the lifting plate 9 is moved upward, and the cutter 10 is moved away from the transmission path of the plastic wire while the two extrusion cylinders 17 drive the plastic wire to fit on the winding roller 6. While the two extrusion cylinders 17 drive the plastic wire toward the winding roller 6, the two extrusion cylinders 17 pull out a section of the plastic wire and finally fit it on the winding roller 6.
