Utility Model Content

[0015] 3. The support column can separate the installation shell from the ground to prevent dust and other impurities on the ground from contaminating the paper roll. When unwinding the paper roll body, the staff will first put the roll sleeve on the fixed sleeve to fix the position of the paper roll body during unwinding, thereby increasing the stability of the position of the paper roll body during unwinding.

[0025] During use, after the deviation correction of the rotating shaft 3 is completed, the staff will start the cylinder 15. The extension of the telescopic rod of the cylinder 15 will drive the limit hook plate 16 to rotate with the rotating column 18 as the center, and make the hook part of the limit hook plate 16 squeeze and fit on the surface of the rotating shaft 3, so as to limit the rotating shaft 3 and prevent the rotating shaft 3 from deviating again after the deviation correction is adjusted.
