Problems solved by technology
During the production of Rutherford cables, the pay-off cradle needs to ensure that the superconducting wires are laid out horizontally, and the winch plate on which the cradle is installed needs to perform a rotary motion, which will increase the difficulty of realizing the automation of the pay-off tension. In addition, each cradle pays off the wire Uneven tension will affect the forming effect of Rutherford cables and increase the scrap rate of Rutherford cables;
[0003] At present, most of the existing Rutherford cable pay-off devices are friction-type damping methods, and the friction of the brake disc is controlled by the brake band, which will lead to inaccurate tension control, and the tension of each pay-off is different. When adjusting the tension, it is necessary to stop the machine and adjust the tension one by one to reduce production efficiency; in addition, there are also tension adjustment and control using damping adjusters, transmission gear sets or motors, but their structures are complex and costly, resulting in waste of resources

The invention discloses a tension-adjustable payoff device in production of a Rutherford cable. The tension-adjustable payoff device in production of the Rutherford cable comprises a base, a hollow spindle, a stranding cage disc and a cradle device. The tension-adjustable payoff device is characterized in that the tension-adjustable payoff device also comprises a slip ring 1, a wire 1, a control cabinet and a wire 2. The control cabinet for carrying out tension control on the cradle device is connected with the front end of the slip ring 1 through the wire 1; the slip ring 1 is fixedly arranged on the base; the back end of the slip ring 1 is connected with one end of the wire 2; the stranding cage disc is sleeved on the hollow spindle; the hollow spindle is provided with a small hole in the position making contact with the stranding cage disc; and the other end of the wire 2 passes through the small hole from the inner portion of the hollow spindle and is connected with the cradle device. The tension-adjustable payoff device in production of the Rutherford cable, under the condition of not halting, through tension setting of the control cabinet, realizes adjustment of payoff tension, and ensures constant tension; and the payoff device is simple in structure and convenient to operate, realizes stable tension output and improves tension accuracy.
Description
technical field [0001] The invention relates to a pay-off device, in particular to a pay-off device with adjustable tension in Rutherford cable production, which belongs to the field of wire pay-off equipment. Background technique [0002] Rutherford cable refers to a double-layer flat cable formed by gradually deforming a certain number of superconducting wires. During the production of Rutherford cables, the pay-off cradle needs to ensure that the superconducting wires are laid out horizontally, and the winch plate on which the cradle is installed needs to perform a rotary motion, which will increase the difficulty of realizing the automation of the pay-off tension. In addition, each cradle pays off the wire Uneven tension will affect the forming effect of Rutherford cables and increase the scrap rate of Rutherford cables; [0003] At present, most of the existing Rutherford cable pay-off devices are friction-type damping methods, and the friction of the brake disc is con...
