Inside the frame 31, guide wheels 32 are arranged in an up-and-down distribution. The guide wheels 32 are rotatably connected inside the frame 31. One end of the guide wheel 32 is connected to the output end of the stepping motor 33. The guide wheel 32 is driven to rotate by the stepping motor 33, and the guide wheel 32 squeezes and clamps the PET plastic steel wire and rotates and drives it.
[0022] A guide post 4 is arranged on the workbench 1. The guide post 4 is perpendicular to the bracket 2. A guide groove 41 is arranged on the guide post 4. A pressing mechanism 5 is arranged in the guide groove 41. A knife groove 42 is arranged on the guide post 4. The guide groove 41 guides the PET plastic steel wire to pass through the guide post 4, straightening the PET plastic steel wire and facilitating cutting.
[0023] A cutting device 6 is arranged on the workbench 1 and on one side of the guide post 4. The cutting device 6 includes a hinge seat 61 and a cutter 62. The hinge seat 61 is bolted to the workbench 1. One end of the cutter 62 is hinged to the hinge seat 61. The cutting device 6 cuts the PET plastic steel wire. After the PET plastic steel wire is pressed by the pressing mechanism 5, the hinged cutter 62 cuts the PET plastic steel wire.
