When the printing medium on the unwinding roller 2140 in the feeding mechanism 2100 is completely unwound, and the unwinding roller 2140 needs to be removed, the piston end of the first cylinder 2130 is driven to contract to drive the lifting piece 2110 to rotate counterclockwise, so that the stagnation accommodating groove of the lifting piece 2110 rises to the limiting groove 2041. When the lifting member 2110 rotates clockwise, the lifting member 2110 abuts against the rolling member 2160 at one end of the locking member 2150, so that the locking member 2150 rotates counterclockwise to the position shown in fig. 15, at this time, the end of the locking member 2150, which is provided with the locking groove, no longer covers the opening of the limiting groove 2041, and the user pushes the unwinding roller 2140 into the retention groove. When the piston end of the first cylinder 2130 is extended, the lifting member 2110 rotates counterclockwise such that the lifting member 2110 no longer abuts the roller member 2160 of the locking member 2150, and the locking member 2150 returns to the normal position as shown in fig. 16; and the lifting piece 2110 rotates anticlockwise, so that the stagnation accommodating groove of the lifting piece 2110 descends, and the unreeling roller 2140 is driven to descend. The first cylinder 2130 may be replaced by a hydraulic cylinder or an electric push rod in this embodiment. The structure of the blanking mechanism 2900 is the same as that of the feeding mechanism 2100 except that the unwinding roller 2140 is replaced by a winding roller, and the other structure and operation principle of the blanking mechanism 2900 are the same as those of the feeding mechanism 2100.
