[0025] In use, the cloth roll is placed in the feeding space 002 of the feeding frame 3. At this time, the lifting claws 27 are placed below the cloth roll. The fixed rod 29 is moved upward by cooperating with the hydraulic cylinder 28, so that the one end of the plurality of lifting claws 27 is synchronously moved upward, and then the lifting claws 27 lift the cloth roll and send it into the unwinding space 001. The cloth roll does not need to be manually placed into the unwinding space 001, which saves time and effort. At this time, the cloth roll is placed on the transmission roller 6, and the limiting rod 26 limits the cloth roll to prevent the cloth roll from moving out of the unwinding space 001 when rotating, which is not conducive to the unwinding of the cloth 07 on the cloth roll.
