[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model connects the cylinder to push the cylinder, the auxiliary disc and the auxiliary cylinder to move in the circular groove. When the auxiliary cylinder completely penetrates the paper roll and the auxiliary disc contacts the paper roll, the paper roll is pushed toward the motor by the cylinder.

[0012] 2. The utility model disconnects the motor and the cylinder contracts inward. When the wound paper roll contacts the support seat, the paper roll cannot enter the circular groove because its thickness is greater than the circular groove, that is, only the auxiliary cylinder, the auxiliary disc and the column are received in the circular groove. When the auxiliary cylinder completely enters the circular groove, the paper roll falls downward and moves along the slope. When the winding film on the paper roll contacts the blade, it is cut off, thereby realizing the automatic discharge and cutting functions of the wound paper roll. BRIEF DESCRIPTION OF THE DRAWINGS
