Wire rewinding pay-off rack and wire rewinding system

The utility model relates to a wire rewinding pay-off rack and a wire rewinding system.The wire rewinding pay-off rack comprises a base, a first rotating shaft, a pay-off tray and an air compression butterfly brake, a brake disc is rotationally connected to the base, one end of the first rotating shaft is rotationally connected to the base, and the first rotating shaft is connected with the brake disc to drive the brake disc to rotate; a pay-off tray is arranged on the first rotating shaft in a penetrating manner and is fixedly connected with the first rotating shaft; and the air compression butterfly brake is fixed on the base and is used for braking the brake disc. According to the device, a magnetic powder clutch is abandoned, air pressure control is adopted, and the situation that magnetic powder loses efficacy due to oxidation sintering, and consequently the wire is likely to loosen or be snapped in the pay-off process can be avoided. And by means of air pressure control, the responsiveness is better, op
