In such an embodiment, under the action of the first compression spring 533, the pressing wheel 531 applies a pressure to one side of the clamping portion 54, and the pressing portion 53 can always abut against the outer side of the formed paper roll in a state that the paper tape 8 is wound on the outer side of the clamping portion 54 one by one, so as to overcome the tension of the paper and effectively prevent the structure of the paper roll from being loosened.

Fig. 8 is a schematic view of a state in which the nip portion 54 nips the paper in the exemplary embodiment shown in fig. 1. Fig. 9 is a schematic view of a state in which the nip 54 of the exemplary embodiment shown in fig. 1 winds paper.

In such an embodiment, the fixed lever 541 and the movable lever 542 are each configured in a semi-cylindrical structure, and a gap formed between the movable lever 542 and the fixed lever 541 is adapted to receive a front end portion of paper to penetrate therethrough in a state where the movable lever 542 is at a position separated from the fixed lever 541. As shown in fig. 8, after the movable lever 542 is driven by the second driving unit 56 to move to the clamping position so that the movable lever 542 and the fixed lever 541 clamp and fix the leading end portion of the paper, as shown in fig. 9, the rotary disk 52 is driven by the first driving unit 55 to rotate so that the paper of the paper tape 8 is wound around the outside of the winding mechanism 5 one by one (since the thickness of the paper is small, the distance between the movable lever 542 and the fixed lever 541 is negligible, and the axes thereof overlap). After the paper tape 8 is wound for a predetermined number of turns to reach a predetermined thickness, the fixing rod 541 is moved away from the movable rod 542 to release the clamping portion 54 for a short time and re-clamp the end of the paper tape 8 after a hollow cylindrical space is formed in the center of the paper tape so as to facilitate removal of the paper tape after the winding is completed. After the paper document is rolled, the paper roll structure can be taken down along the axial end of the clamping part 54, and then the paper document with the paper roll structure is filed and stored (in order to prevent the taken-down paper roll structure from being loose, at least one of a protective sleeve, an elastic tape or a colloid is sleeved on the outer side of the paper roll structure to seal the position of the notch 84 of the paper roll structure so as to tie up the paper roll structure).

In such an embodiment, the second compression spring 32 is adapted to urge the conveying roller 33 against the table top (upper surface as shown in fig. 1) of the platform 6. The third motor drives the conveying roller 33 to rotate around the shaft so that the paper between the table top and the conveying roller 33 is conveyed along the upper surface of the table top by the friction force.

In an exemplary embodiment, the rotational speeds of the conveying rollers 33 of both conveying assemblies are configured to be independently controlled so that the two conveying rollers 33 can rotate at the same speed or at different speeds. Such that the first sheet 81 conveyed by one conveying roller 33 and the second sheet 82 conveyed by the other conveying roller 33 can be formed at the same or different speeds so that the overlapping portion of the first sheet 81 and the second sheet 82 can be controlled.

According to the embodiment of the present invention, as shown in fig. 1, the binding mechanism 7 is disposed between two conveying assemblies and is in communication connection with the conveying assemblies, so that the conveying roller 33 stops rotating in a state where the sheets are bound, to maintain the position of the sheets with respect to the binding mechanism 7.
