During the combing process, the friction between the plastic wire 11 and the gear rod is large, resulting in poor protection of the plastic wire 11. The film passes through the pad 3 and the mounting frame 4, and the multiple groups of cutting knives 6 on the mounting frame 4 cut the film into multiple groups of plastic wires 11, and then the plastic wire 11 passes through the combing wire.

[0019] During the wire drawing process of the plastic wire 11, the plastic wire 11 will contact the rotating ring 9 and the rotating rod 10 on the combing rod 7, and can rotate freely through the rotating ring 9 and the rotating rod 10. When the plastic wire 11 contacts the rotating ring 9 and the rotating rod 10, the rotating ring 9 and the rotating rod 10 will be driven to rotate, thereby reducing the friction between the plastic wire 11 and the combing rod 7, avoiding the breakage of the plastic wire 11, and helping to improve the protection of the plastic wire 11.

[0020] Working principle: in the process of drawing the plastic wire 11 by the existing wire drawing device, in order to avoid the entanglement of the plastic wire 11, the plastic wire 11 needs to be combed and stripped, and the wire drawing is separated by setting a plurality of gear rods.

Then the plastic wire 11 passes through the combing rod 7, and the rotating rod 10 on the combing rod 7 isolates the plastic wire 11 into strips. Then the plastic wire 11 bypasses the guide roller 13, and then the plastic wire 11 passes through the first drawing roller 18 and the second drawing roller 19, and is driven by the motor 22 to rotate the first rotating shaft 16, and the first rotating shaft 16 drives The first gear 20 rotates, and the first gear 20 pushes the second gear 21 to rotate, and the second gear 21 drives the second rotating shaft 17 to rotate, that is, the first rotating shaft 16 and the second rotating shaft 17 rotate synchronously relative to each other, driving the first wire drawing roller 18 and the second wire drawing roller 19 to rotate synchronously relative to each other, and the first wire drawing roller 18 and the second wire drawing roller 19 stretch the plastic wire 11 to achieve wire drawing processing; in the process of wire drawing of the plastic wire 11, the plastic wire 11 will contact the rotating ring 9 and the rotating rod 10 on the combing rod 7, and can rotate freely through the rotating ring 9 and the rotating rod 10. When the plastic wire 11 contacts the rotating ring 9 and the rotating rod 10, it will drive the rotating ring 9 and the rotating rod 10 to rotate, reducing the friction between the plastic wire 11 and the combing rod 7, avoiding the breakage of the plastic wire 11, which is beneficial to improving the protection of the plastic wire 11.
