The invention discloses a steel cord pay-off tension control device. The device comprises a first supporting ring, wherein a plurality of through holes are evenly formed in the periphery of the firstsupporting ring, first spring rods are movably arranged in the through holes, the first spring rods can only move in the through holes away from and close to the axis of the first supporting ring, external threads are formed in the inner sides of the peripheries of first spring rod fixing rods, nuts are installed in the external threads, the peripheries of the nuts are connected with the inner periphery of conical friction wheels, and the sides, close to the inner wall of the first supporting ring, of the conical friction wheels are rotationally connected with the inner wall of the first supporting ring through bearings. The pay-off tension control device is simple in structure and ingenious in conception, the positions of arc-shaped friction blocks can be automatically adjusted accordingto the abrasion condition
