The application relates to the winding field and discloses a winding material winding support device and a winding equipment. The winding material winding support device comprises a mounting frame, a winding frame, a winding shaft and a support shaft. The mounting frame has a containing space. An inclined guide groove is arranged on the side wall of the containing space along a first direction. The winding frame is arranged in the containing space. The winding shaft is rotatably arranged on the winding frame. The two ends of the support shaft are slidably arranged in the guide groove. The two ends of the support shaft are slidably arranged in the inclined guide groove of the side wall of the mounting frame. Under the action of gravity, the support shaft automatically slides along the guide groove and abuts against the peripheral surface of the winding shaft, thereby providing rigid support for the printed medium in the form of a small roll in the initial winding stage. The support shaft directly lifts the medium in the sagging area, eliminates the relaxation and sagging of the medium, ensures that the medium maintains horizontal tension during the winding process, and enables the medium to be stacked and wound on the winding core in a flat and uniform manner, thereby solving the problem of longitudinal creases of the medium caused by the sagging of the winding shaft.
