[0033] Before cutting the release film, two rolled release film tubes are placed on both sides of the table top of the processing table 1, and the two release film tubes are fixed, and then the dual-axis motor 8 is started to rotate the two worm gears 9, and the two rotating rods 3 and the cutting wheel 4 are rotated at the same time through the engagement of the worm gear 9 and the worm wheel 10, and then the driving motor 14 is started to drive the reciprocating screw rod 16 to rotate.

[0034] Example 2

[0035] Embodiment 2 is based on Embodiment 1 in order to stably clamp the release film tube before cutting.
