Background technique

Stranding machine is an important equipment in wire and cable production equipment. It mainly twists multiple single lines into a single wire or cable according to the design requirements. Turning to enter the twisted bow, through the rotation of the twisted bow, the multi-strand wires are twisted into shape, and the length of the twist formed by twisting is controlled by the mechanically driven traction wheel that operates in the same proportion as the twisted bow speed. When changing the twisted length, it is necessary to To change the linear speed of the traction pulley, there are generally two ways to change the transmission ratio without changing the wheel diameter and to change the wheel diameter without changing the transmission ratio. On the wire reel; such a mechanism is relatively complicated, and the linear speed of the traction wheel relative to the rotation speed of the winch bow must be changed to achieve the adjustment of the twist pitch. At the same time, when twisting wires, the tension of the wire harness caused by the speed change due to untimely adjustment often does not meet the requirements, which directly affects the product quality, and may even cause the wire harness to break, bringing economic losses to the enterprise.
