The air roller structure of this paperboard unwinding machine uses a clamping plate to increase the contact area between the air roller and the paper roll, thereby initially preventing the paper roll from loosening. Furthermore, the anti-slip pads on the outside of the clamping plate increase the friction, further preventing the paper roll from loosening. This results in a larger contact area between the air roller and the paper roll, preventing the paper roll from loosening during the unwinding process.

[0018] 2. The air-expansion roller structure of this paperboard unwinding machine uses high-pressure gas to input into the roller body, causing the piston rod to drive the pressing plate to move. The pressing plate then presses against the inside of the paper roll, thereby fixing the paper roll in place. By moving the pressing plate a different distance with the piston rod, the pressing plate can press against paper rolls of different specifications, thus enabling the air-expansion roller to be used with paper rolls of different specifications, resulting in a high air-expansion roller performance.
