[0063] When the film roll 1 is conveyed to the trimming unit 3 by the conveyor 51, the lifting screw module 521 drives the lifting plate 522 at the top pipe mechanism I 32 to rise, so that the film roll 1 rises to the coaxial position of the center pipe and the first center pin 321 and the second center pin 322. Then the first cylinder 323 drives the first center pin 321 to insert into the positioning hole at one end of the center pipe, and the second cylinder 324 drives the second center pin 322 to insert into the positioning hole at the other end of the center pipe.
