[0029] Reference Figure 3-Figure 5The top of the gantry 3 is fixedly connected with an air pump 19, and the output end of the air pump 19 is fixedly connected with a fixed pipe 20 through a telescopic hose. The telescopic hose can be telescopically deformed when the lifting frame 5 is lifted, so as to ensure that the air pump 19 is connected to the fixed pipe 20. The lifting frame 5 also provides a fixing function for the fixed pipe 20. The outer wall of the fixed pipe 20 is fixedly connected with a collar 21, and the inner surface of the collar 21 is rotatably connected with a hollow ring 22. The area of ​​the hollow ring 22 that contacts the collar 21 is open, so that the fixed pipe 20 can introduce the wind source into the interior of the hollow ring 22.

[0030] Working principle: after the cable is twisted through the twisting mechanism 1, it is guided and reeled through the twisting wheel 8, and the cylinder 4 is started. The cylinder 4 drives the lifting frame 5 to adjust the height, and the motor 6 drives the rotating shaft 7 to make the twisting wheel 8 rotate counterclockwise to twist the cable. When the twisting wheel 8 and the cable are twisted, the rubber block 12 will contact with it. Due to the inclined direction of the rubber block 12, it helps the cable to transition to the twisting wheel 8 more smoothly, improve the twisting effect, and prevent the cable from being stuck or damaged at the contact point. At the same time, it can adapt to cables of different thicknesses and provide a more flexible twisting method for the cable. When it is necessary to adjust the degree of contact between the rubber block 12 and the cable, before the twisting wheel 8 twists the cable, the dial ring 15 is manually dialed, and the dial ring 15 drives the bidirectional screw rod 14 to rotate, so that the two groups of threaded blocks 13 drive the two groups of connecting rods 10 to move inside the through hole 11, and the two groups of rubber blocks 12 The forces can be close to or away from each other. When the rubber block 12 is displaced, the two groups of support rods 18 will drive the slider 25 to slide inside the slide groove 17 to ensure the adjustment stability of the rubber block 12, thereby adjusting the friction coefficient of the contact point between the cable and the stranding wheel 8, and reducing the friction resistance in the stranding process. When the stranding wheel 8 is on the way of stranding the cable, the air pump 19 draws in the outside air and passes it through the filter. After being filtered, it is transmitted to the inside of the hollow ring 22 through the fixed pipe 20. The air supply pipe 23 introduces air into the inside of the stranding wheel 8 and finally sprays it out through multiple groups of through holes 24. The cable contacts the stranded wire. Blowing can reduce the accumulation of static electricity caused by friction during the stranding process. At the same time, the friction between the cable and the stranding wheel 8 may generate a lot of heat. The heat on the surface of the cable is removed through the heat exchange principle by blowing heat, thereby avoiding overheating of the cable and ensuring the product quality of the cable in production.

The above is only a preferred embodiment of the present invention.
