When more and more paper is on the rewinding roller 606, the damper 804 and the spring 805 will drive the arc plate 806 to move downward, which will not hinder the rewinding operation on the rewinding roller 606. At the same time, the elastic force of the spring 805 will provide tension to the rewinding roller 606 to maintain the tightness of the rewinding roller 606 during rewinding.

[0041] When the paper roll is rewound for a certain period of time, the first motor 3 is controlled to stop, the control system controls the cylinder rod of the first telescopic cylinder 708 to extend, the cylinder rod drives the slide plate 702 to slide on the track 701 toward the direction close to the tensioning device 8, the slide plate 702 drives the mounting plate 703 to slide, the mounting plate 703 drives the waste box 704 to slide, the waste box 704 drives the fan 705 to slide, the fan 705 drives the adsorption plate 706 to slide, and when it slides to the position of the paper to be cut, the fan 705 is controlled to start, and the control system controls the second motor 503 rotates, the second motor 503 drives the first screw rod 504 to rotate, the first screw rod 504 drives the slider 505 to slide on the first screw rod 504, the slider 505 drives the glue box 506 to slide, the glue box 506 drives the cutting knife 507 to slide, and the paper between the unwinding roller 4 and the rewinding roller 606 is cut, and the electromagnetic dispensing valve 508 is controlled to start, and glue is sprayed on the paper on both sides, and the fan 705 drives the adsorption plate 706 to absorb the paper scraps during cutting, and at the same time absorbs the end of the paper close to the unwinding roller 4.

[0042] After the cutting knife 507 cuts the paper between the unwinding roller 4 and the rewinding roller 606, the fourth motor 604 is controlled to rotate, and the fourth motor 604 drives the rewinding roller 606 to rotate, so that the end of the glue-sprayed paper sticks to the paper roll. When the rewinding is completed, the control system controls the cylinder rod of the first lifting cylinder 803 to retract, and the cylinder rod drives the first lifting plate 802 to slide downward, and the first lifting plate 802 drives the arc plate 806 to slide downward, so that the arc plate 806 does not affect the rotation of the rotating plate 603. The control system controls the third motor 602 to rotate, and the third motor 602 drives the rotating plate 603 to rotate, and rotates the rewinding roller 606 in the rewinding position to the unloading position.

[0043] When the rotating device 6 rotates the rewinding roller 606 that has completed rewinding to the unloading position, the cylinder rod of the first telescopic cylinder 708 is controlled to extend, and the cylinder rod drives the fan 705 to slide in the direction of the rewinding roller 606. The fan 705 drives the adsorption plate 706 to stick the end of the glue-sprayed paper to the rewinding roller 606 in the rewinding position, and controls the first motor 3 and the fourth motor 604 to rotate, and rewinds the paper on the unwinding roller 4 onto the rewinding roller 606.

[0044] When the rewinding roller 606 rotates to the unloading position after the rewinding is completed, the control system controls the cylinder rod of the second lifting cylinder 903 to extend, and the cylinder rod drives the unloading plate 907 and the long plate 908 to slide upward. When the electric heating tube 909 moves to be coaxial with the groove 607, the cylinder rod of the second telescopic cylinder 910 is controlled to extend, and the cylinder rod drives the long plate 908 to move away from the second telescopic cylinder 910. When the electric heating tube 909 completely enters the groove 607, the electric heating tube 909 is controlled to heat up, so that the glue stuck on the rewinding roller 606 falls off due to the heat. After the electric heating tube 909 heats up for a period of time, the electric heating tube 909 is controlled to stop heating, and the second telescopic cylinder 910 is controlled to stop heating. The cylinder rod of the cylinder 910 is retracted, and the cylinder rod drives the long plate 908 to move toward the direction close to the second telescopic cylinder 910. When the electric heating tube 909 moves out of the groove 607, the cylinder rod of the second lifting cylinder 903 is controlled to extend, and the cylinder rod drives the second lifting plate 902 to continue to move upward. When the paper roll on the rewinding roller 606 is completely in the through groove of the long plate 908, the fifth motor 905 is controlled to rotate, and the fifth motor 905 drives the second screw rod 906 to rotate. The second screw rod 906 drives the unloading plate 907 to slide in the direction away from the fifth motor 905. The unloading plate 907 pushes the paper roll to be unloaded from the through groove of the long plate 908 and enters the next process.

[0045] When unloading is completed, the control system controls the cylinder rod of the second lifting cylinder 903 to retract, and the cylinder rod drives the second lifting plate 902 to slide downward, and the second lifting plate 902 drives the unloading plate 907 to slide downward, so that the unloading plate 907 does not affect the rotation of the rotating plate 603.
