Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable stranding, specifically a kind of adjustable power cable stranding device and method. BACKGROUND

[0002] The cable stranding device is a kind of mechanical equipment for producing cable, mainly used for stranding multiple thin wires or conductors according to certain order and mode into a cable. It is widely used in power, communication, industrial automation and other fields, especially in the production of power cable, control cable, communication cable, etc.

[0003] At present, the cable stranding device in the prior art has many deficiencies. For example, the tension control of traditional equipment is not accurate enough in the stranding process, which leads to uneven tension of each cable, which not only easily causes deformation or damage of the cable at the stranding point, but also affects the electrical performance and mechanical strength of the final product. Secondly, the cable is often tangled and knotted during winding and unwinding due to non-optimal path or fixed guiding device, which increases the frequency of manual intervention and reduces production efficiency, and may cause surface scratches or insulation layer damage of the cable, shortening the service life. In addition, the existing device has complex structure and lacks flexibility in adjustment mechanism, for example, it cannot adjust the cable path length in real time to adapt to different specifications or stranding requirements, which limits the universality and adaptability of the equipment. Especially in high-speed stranding operation, there is a lack of effective tension balance and anti-winding design, which easily leads to cable accumulation, interruption or quality defects, causing material waste and cost increase.
