[0002] A cable stranding machine is a mechanical device applied in the wire and cable processing industry. Its main function is to twist multiple wires or conductors together according to a certain rule to form a wire and cable product with a certain strength and structure. The stranding machine generally consists of a frame, a stranding system, a tension adjustment system, a wire take-up device, etc. The frame is the supporting structure of the entire device. The stranding system consists of a series of rotating dies, which are used to twist multiple wires together according to a certain rule. The tension adjustment system is used to adjust the tension of the wires during the stranding process to ensure the stranding quality. The wire take-up device winds up the stranded wires to form a product with a certain structure. At the stranding part, a fixed tubular object is often used for stranding, which is not convenient for replacing the components at the stranding part. And for the heavier stranding part, a single transmission part is used, which is not conducive to the rotational stability of the longer stranding device. Content of the Utility Model

The rotating wheel 12 and the rotating wheel 2 14 are one of a pulley, a sprocket and a synchronous pulley. The transmission belt 13 is one of a belt, a chain and a synchronous belt that cooperates with the rotating wheel 12 and the rotating wheel 2 14. The fixed box 3 and the rotary support seat 5 are preferably rotatably connected through a bearing. The connection between the rotary support seat 5 and the fixed box 3 passes through the support tube 4.
