[0052] Embodiment two:

[0053] Embodiment two of the present application discloses a winding and overturning mechanism. Referring to Figures 6-7 , the difference between the present embodiment two and the embodiment one is that the outer frame 1 is provided with a first locking member 12 for locking the rotating gear ring 33, a second locking member 13 for locking the first rotating shaft 21, and a third locking member 14 for locking the second rotating shaft 26.

When the unlocking disc 15 rotates, the unlocking lever 151 can pass through the first guide groove 1222 and the second guide groove 1322 in sequence.

[0056] When the unlocking lever 151 moves in the first guide slot 1222, the first locking tooth 121 gradually disengages from the inner ring 331, and then the first locking member 12 is in the unlocking state and the second locking member 13 is in the locking state.

Similarly, when the first roll 4 performs the winding operation, the second locking member 13 is in the unlocked state, and the first locking member 12 and the third locking member 14 are in the locked state; when the second roll 5 performs the winding operation, the third locking member 14 is in the unlocked state, and the first locking member 12 and the second locking member 13 are in the locked state.

[0065] Referring to Figure 12 and Figure 14 , the transverse cutting member 9 comprises a transverse cutting knife 91, a transverse moving piece 92 used for driving the transverse movement of the transverse cutting knife 91, and a linear module 93 used for driving the transverse moving piece 92 to move towards or away from the rotary frame 2.
