The utility model provides a winding tension adjustment mechanism for a rotor spinning machine, and belongs to the technical field of textile mechanical components and parts. The tension adjustment device comprises a first conical pulley, a second conical pulley, a first transmission shaft, a second transmission shaft, a driving belt, a helical gear, a screw rod and a clamping roller, wherein the first transmission shaft and the second transmission shaft are parallel to a winding shaft and a doffing shaft, and are respectively in transmission connection with the doffing shaft and the winding shaft; the first conical pulley and the second conical pulley are respectively sleeved on the first transmission shaft and the second transmission shaft; the big end of the first conical pulley corresponds to the small end of the second conical pulley; the driving belt is sleeved on the outer surfaces of the first and second conical pulleys and matched with the first and second conical pulleys; the output shaft of a doffing motor is in transmission connection with the second transmission shaft; the axis of the screw rod is parallel to the first transmission shaft and the second transmission shaft; the clamping roller is movably sleeved on the driving belt and fixedly connected with the helical gear; and the helical gear is matched with the screw rod. The winding tension adjustment mechanism can be used for solving the problem that an existing rotor spinning machine is not convenient in winding tension adjustment and does not have a good adjustment effect.
