During the sliding process, The spring 808 brings the block 809 into the hole 807.

[0023] Furthermore, multiple groups of bases 2 are arranged on the bottom surface of the bracket 1, and are symmetrically arranged at the four corners of the bracket 1 with respect to the central axis of the bracket 1. Through the arrangement of the base 2, the arrangement of multiple groups of bases 2 can increase the friction between the bracket 1 and the contact surface, making it more stable when placed on the ground.

[0024] Furthermore, the rotating mechanism 7 includes a driving motor 701, a rotating shaft 702, a transmission gear 703, a rotating gear 704, a first rotating rod 705, a second rotating rod 706, a guide wheel 707 and a guide rod 708. The upper surface of the fixed plate 3 is fixedly connected to the driving motor 701, one end surface of the driving motor 701 is fixedly connected to the rotating shaft 702, the outer wall surface of the rotating shaft 702 is fixedly connected to the transmission gear 703, the outer wall surface of the transmission gear 703 is meshed with the rotating gear 704, one end surface of the rotating shaft 702 is fixedly connected to the first rotating rod 705, one end surface of the rotating gear 704 is fixedly connected to the second rotating rod 706, the inner wall surface of the second rotating rod 706 is rotatably connected to the guide wheel 707, and one end surface of the rotating shaft 702 is fixedly connected to the guide rod 708.

When the stranding machine is in use, the driving motor 701 is started, the rotating shaft 702 drives the transmission gear 703 to rotate, and the rotating gear 704 meshing therewith rotates at the same time, the first rotating rod 705 drives the two sets of guide wheels 707 to rotate greatly, and the rotating gear 704 drives the second rotating rod 706 to rotate, so that the second rotating rod 706 drives the guide wheel 707 to complete a small rotation. Through rotation, the relative movement between the guide wheel 707 and the stranded wire is smoother, reducing friction resistance, and sending the wire wrapped on the surface of the guide wheel 707 to the guide rod 708, so that it passes through the holes at both ends of the guide rod 708 and is sent to the tension structure for tension.

[0025] Furthermore, the transmission gear 703 forms a rotating structure with the rotating shaft 702 through the driving motor 701, and two groups of guide wheels 707 are symmetrically arranged with the central axis of the bracket 1. Through the arrangement of the driving motor 701, the rotating shaft 702, the transmission gear 703 and the wire wheel 707, the driving motor 701 drives the rotating shaft 702 and the transmission gear 703 to rotate, which can make the guide wheel 707 rotate.

Through the setting of the servo motor 803 and the threaded rod 804, the slider 805 can automatically slide in the slide groove 801 through the threaded hole 806.

[0028] Furthermore, the outer wall size of the block 809 is consistent with the inner wall size of the adjustment hole 802, and the spring 808 and the block 809 cooperate with each other to form a telescopic structure. Through the setting of the adjustment hole 802, the spring 808 and the block 809, the adjustment hole 802 limits the block 809 so that it can play a locking effect on the slider 805.

[0029] Working principle: First, the setting of multiple groups of bases 2 can increase the friction between the bracket 1 and the contact surface, making it more stable when placed on the ground. When the material quality is different, the required tensioning degree is also different. At this time, the tensioning degree can be adjusted by adjusting the height of the tension wheel 811. Start the servo motor 803, and the slider 805 slides up and down in the slide groove 801 through the threaded hole 806 on the inner wall as the threaded rod 804 rotates. During the sliding process, the spring 808 brings the block 809 into the hole 807. Every time it passes through an adjustment hole 802, the spring 808 will bounce the block 809 from the hole 807 into the adjustment hole 802, which has a positioning effect. At the same time, it can also limit the sliding of the slider 805 when the threaded rod 804 stops rotating. As the slider 805 slides, the adjustment rod 810 fixed to it also It will drive the tension wheel 811 to slide up and down, thereby completing the adjustment of the height of the tension wheel 811 and realizing the adjustment of the tension degree of different materials. When the stranding machine is in use, the drive motor 701 is started, and the rotating shaft 702 drives the transmission gear 703 to rotate, and the rotating gear 704 meshing therewith rotates at the same time, and the first rotating rod 705 drives the two sets of guide wheels 707 to rotate greatly, and the rotating gear 704 drives the second rotating rod 706 to rotate, so that the second rotating rod 706 drives the guide wheel 707 to complete a small rotation. Through rotation, the relative movement between the guide wheel 707 and the stranded wire is smoother, reducing friction resistance, and sending the wire wrapped on the surface of the guide wheel 707 to the guide rod 708, so that it passes through the holes at both ends of the guide rod 708 and is sent to the tension wheel 811 for tensioning, thereby completing the use process of a tension device for stranded wire.
