Frame-stranding pay-off rack tension control device

The utility model discloses a frame-stranding pay-off rack tension control device which comprises a base, a box body is fixedly arranged at the top of the base, a rack is fixedly arranged at the top of the box body, a pay-off mechanism is fixedly arranged on the rack, and two guide wheel sets are symmetrically and fixedly arranged at the top of an inner cavity of the rack. The tension detection mechanism and the pressure sensor are used in cooperation to detect the tension of the cable, when the numerical value detected by the pressure sensor is larger than the numerical value set on the single-chip microcomputer controller, the single-chip microcomputer controller controls the motor to increase the rotating speed, and when the numerical value detected by the pressure sensor is smaller than the numerical value set on the single-chip microcomputer controller, the single-chip microcomputer controller controls the motor to increase the rotating speed. The single-chip microcomputer controller can control the moto
