This utility model relates to the field of food processing equipment manufacturing technology, and in particular to a composite motion drive mechanism for a gluten roll winding device, which consists of a torque output unit and a drag force output unit. The winding assembly performs circumferential rotation under the drive of the torque output unit; the unloading cylinder, driven by the drag force output unit, completes axial reciprocating movement, causing the formed gluten to detach. The drag force output unit uses a transmission shaft as its power source, and through the cooperation of a cam mechanism, a multi-component transmission mechanism, a rocking component, and an elastic reset component, converts the power into the reciprocating rocking motion of the rocking component, thereby driving the unloading cylinder to move synchronously. Thus, on the one hand, the composite motion drive mechanism has a relatively simple design structure, and thanks to the operating characteristics of the cam mechanism, the unloading cylinder can achieve non-rigid unloading force application; on the other hand, by adjusting the contour curve of the cam mechanism and the parameters of the multi-component transmission mechanism, and with the assistance of the elastic reset component, the gluten roll winding device can adapt to various unloading requirements.
