[0047] Working principle:

[0048] When winding, the cylinder 1102.1 extends out, and the clamping part 1102.14 is just clamped in the clamping interface of the wire take-up drum 1102.10, and the movable support rod is in a horizontal position. The wire to be taken up passes through the first wire feeding wheel 1101.13, the second connecting rod 1101.12, and the third wire feeding wheel 1101.16 on the left frame and is then taken up by the reel. When winding, the wire pressing wheel presses the wire, and then the wire falls onto the movable support rod around the four wire taking-up rods. As more and more wire is taken up, the lifting telescopic assembly 1102 as a whole rotates and descends with the lifting screw until the winding is completed. Then the trolley moves to the bottom of the reel, the lifting cylinder retracts, the wire support plate 1107.1 rises to the height of the wire rack 1107.2, the wire roll on the movable support rod falls onto the wire support plate 1107.1, the wire take-up drum body falls onto the protective ring, and then the wire is cut, the cylinder 1102.1 retracts, driving the wire take-up drum body to rise and return to its position.

[0049] The lifting cylinder extends, the wire support plate 1107.1 descends, the wire roll on the wire support plate 1107.1 falls onto the wire rack 1107.2, the horizontal cylinder pushes to the right, pushes the trolley to the right, and finally the swing cylinder 1107.6 moves to push the wire roll off the wire rack 1107.2. Since the wire falls freely on the reel, no extra squeezing force is generated during the winding process, reducing the external force on the wire after winding, and ensuring the quality of the wire after winding.
