[0002] In the production process of cable strands, a stranding machine is usually used for production operations. The inner stranded core passes through the through hole in the center of the reel. There are multiple strands of wire, which are arranged around the inner stranded core and pass through the wire holes of the reel. By rotating the reel, the strands are continuously wound around the inner stranded core. During this process, if a single strand is subjected to too much tension, the strand with greater stress will break, which will greatly affect the quality of the finished product and the subsequent processing flow.

The utility model can drive the turntable to rotate by starting the adjusting motor, so that the guide block moves on the inner wall of the arc guide groove, and the position of the guide block changes to drive the lifting rod to move along the lifting rod guide groove as the path, thereby driving the stranded wire to move synchronously, and can adjust the tightness of the stranded wire to avoid low or high tightness of the stranded wire during stranding.

[0005] Therefore, improvements are made to address the above problems. Utility Model Content

A rotating shaft 3-3 is provided at the output end of the wire-paying motor 3-2. A wire-paying drum 3-4 and a fixing screw 3-5 are mounted on the rotating shaft 3-3. The fixing screw 3-5 can connect and fix the wire-protecting drum to the rotating shaft 3-3.

The elastic rod 3-9 shrinks in the groove 3-8, and a distance sensor 3-11 is provided at the bottom of the circular groove 3-8. When the tension of the wire is too large, the elastic rod 3-9 will sink. After sinking to a certain depth, it can be detected by the distance sensor 3-11, so that it can timely find out which wire is too tight and timely speed up the defense line motor. A frame 3-12 is provided on the upper end of the elastic rod 3-9 and two rotating wheels 3-13 are connected to the inside for rotation. The wire passes through the rotating wheels 3-13 and is transported by the rotation of the rotating wheels 3-13.

[0037] Furthermore, the surface of the rotating wheel 3-13 is a concave structure, and the rotating wheels 3-13 fit together.

[0038] In this embodiment, the concave structure allows the two rotating wheels 3-13 to fit together, and the wires can be kept inside without slipping, thereby maintaining stability during transportation.

[0039] Furthermore, the cross section of the connection between the rotating shaft 3-3 and the pay-off reel 3-4 is a polygonal structure.

During the cabling process, the drive motor 4-3 is started to control the shell 2 to rotate at a uniform speed. When the tension of individual wires is too large during the pay-off process, the elastic rod 3-9 will shrink into the circular groove 3-8. After reaching a certain depth, the distance sensor 3-11 generates feedback, and cooperates with the controller 5 to timely control the pay-off motor 3-2 to adjust the pay-off speed. During the pay-off process, the wire can be transported while maintaining its position unchanged, which can protect the wire.
