With this device, when the distance between the first paper pressing frame 1 and the second paper pressing frame 2 changes, the total length of the paper pressing roller can be adjusted, so that different sizes of paper can be processed well.

[0023] Specific working principle: During use, place the placement block 9 on the auxiliary paper pressing roller 8 into the first placement rack 6, align the limit hole 10 on the placement block 9 with the through hole 7 on the first placement rack 6, then pass the limit rod 11 and the threaded rod 13 through the limit hole 10 and the through hole 7, and make the disc 12 closely adhere to the first placement rack 6. Then screw the pressing plate 14 onto the threaded rod 13 to make the pressing plate 14 tightly abut and fix against the surface of the first placement rack 6, so that the auxiliary paper pressing roller 8 can be installed on the cross bar 4, increasing the length of the paper pressing roller. With this device, when the distance between the first paper pressing rack 1 and the second paper pressing rack 2 changes, the total length of the paper pressing roller can be adjusted, so that different sizes of paper can be processed well.
