[0002] A wire harness usually refers to a group of wires, cables or optical fibers that are bundled or woven together to facilitate the transmission of power, data or signals. These wire harnesses are usually used in various fields such as electronic equipment, automobiles, aerospace vehicles, and industrial machinery. When recycling and reprocessing the wire harness, a stripping machine is usually used. A wire harness stripping machine is a device used to strip the outer insulation material of wires or cables.

[0030] Specifically, the rotating shaft 4 can drive the turntable 11 to rotate, and when the turntable 11 rotates, the vortex teeth 16 will also rotate.

When the tooth block 15 moves, it can drive the corresponding fixed plates 7 to approach or move away at the same time through the fixed connecting rod 8, so that it can be adjusted according to the different inner diameters of the wire harness roll, and under the action of the groove 6, the fixed plate 7 can also be stuck in the groove 6 to ensure the minimum inner diameter of the wire harness ring that can be applied to the pay-off shaft 3, so as to achieve the effect of being applicable to wire harness rolls of different specifications.

[0031] Reference Figure 1-Figure 3 The leveling mechanism 2 includes a bracket 201, which is fixedly connected to the other side of the top wall of the base 1, and a connecting plate 202 is fixedly connected to the top wall of the bracket 201.

[0032] Specifically, by starting the servo motor 209, the bidirectional screw 212 can be driven to rotate, and under the action of the two limit rods 213, the movable frame 210 connected to the bidirectional screw 212 cannot rotate, so that the movable frame 210 connected to the front and rear ends of the bidirectional screw 212 will drive the roller 214 to approach each other, so that the stripped wire harness can be leveled from the front and back sides, and by starting the servo motor 1 204, the bidirectional screw 1 205 can be driven to rotate.
