1. A winding shaft, for winding plates and comprising:
a winding shaft body comprising a first winding surface;
an adjustment member configured to be mounted on the winding shaft body and movable simultaneously in an axial direction of the winding shaft and in a radial direction of the winding shaft, wherein the adjustment member comprises a second winding surface, and the first winding surface and the second winding surface are configured to wind the plates jointly, wherein the adjustment member comprises a first end and a second end that are opposite each other in the axial direction of the winding shaft;
an actuator configured to drive the adjustment member to move to change a relative position of the second winding surface with respect to the first winding surface to change a winding circumference of the winding shaft; and
an elastic member, wherein the elastic member is for connecting the winding shaft body and the adjustment member, and the elastic member is configured to be compressed or stretched to apply an acting force to the adjustment member in the axial direction of the winding shaft and/or the radial direction of the winding shaft; and, wherein
in the axial direction of the winding shaft, at least part of the elastic member is located between the first end and the winding shaft body, the actuator is connected to the second end, the elastic member is compressed or released during movement of the adjustment member, and the elastic member is configured to apply an acting force to the adjustment member in the axial direction of the winding shaft during movement of the adjustment member; or
in the axial direction of the winding shaft, at least part of the elastic member is located between the second end and the winding shaft body, the actuator is connected to the second end, the elastic member is stretched or released during movement of the adjustment member, and the elastic member is configured to apply an acting force to the adjustment member in the axial direction of the winding shaft during movement of the adjustment member.
