[0033] With reference to Figure 2 - Figure 4, the outer wall of the rotating shaft 24 and the interior of the mounting frame 1 are jointly provided with a control component 26, the control component 26 includes a mounting groove 261, the mounting groove 261 is in the shape of a cylindrical groove and an annular groove connected together, the mounting groove 261 is opened on the inner wall of the mounting frame 1 above the slide groove 22, the inner wall of the mounting groove 261 is fixedly connected with a fixing rod 262, the fixing rod 262 is in the shape of a cylinder, the mounting groove 261 is rotatably connected to the inner wall of the outer side of the fixing rod 262 with a rotating sleeve 263, the rotating sleeve 263 is in the shape of a circular tube, and the circles corresponding to the cross-sections of the rotating sleeve 263 and the fixing rod 262 are concentric circles, and the mounting groove 261 is in the fixed The inner wall of the outer side of the fixed rod 262 is provided with an annular area whose inner and outer diameters are both matched with the shape of the rotating sleeve 263. The number of mounting grooves 261 is set to two, and the annular area of ​​the mounting groove 261 is set on the side where the two mounting grooves 261 are away from each other, and the length of the fixed rod 262 is consistent with the distance between the annular areas of the two mounting grooves 261. By setting the distance, it is ensured that when the rotating sleeve 263 is inside the annular area of ​​the mounting groove 261, it is limited by the inner wall of other areas of the mounting groove 261, so it can and can only rotate relative to the mounting groove 261, and cannot move, thereby achieving the expected effect, and at the same time does not affect the installation of the fixed rod 262.

[0034] Reference Figure 2 - Figure 4 The inner wall of the rotating sleeve 263 and the outer wall of the fixed rod 262 are elastically connected by a torsion spring 264. One end of the torsion spring 264 is fixedly connected to the inner wall of the rotating sleeve 263, and the other end of the torsion spring 264 is fixedly connected to the outer wall of the fixed rod 262. The product of the number of rotatable turns of the torsion spring 264 and the outer diameter of the rotating sleeve 263 is greater than the length of the damping rope 265.

[0036] When the stainless steel wire rope stranding machine starts working, when the required tension of the stainless steel wire rope decreases, the torsion spring 264 drives the rotating sleeve 263 to rotate under the action of the torsion force, so that the rotating sleeve 263 causes the damping rope 265 to be wrapped around its outer wall during rotation, thereby shortening the length of the damping rope 265 between the rotating sleeve 263 and the damping disk 266.

[0037] With the damping rope 265 becoming shorter, the damping disc 266 is driven by the damping rope 265 to move upwards, so that the control wheel 25 moves upwards, when the control wheel 25 moves upwards, the length of the stainless steel wire rope between the two positioning wheels 21 and the control wheel 25 changes, so that the total length of the stainless steel wire rope that is stretched changes, so as to change the tension change amount of the stainless steel wire rope, and the single movement can make the tension change amount of the stainless steel wire rope greater.

[0038] At the same time, since the sliding block 23 is inside the sliding groove 22, the paths of the sliding block 23, the rotating shaft 24 and the control wheel 25 moving up and down are fixed, so that the control wheel 25 will not deviate during movement.
