[0028] In the embodiment, if the winding tension is adjusted too large during winding, the paper will be deformed with both sides upturned, the paper will be folded during winding, and the winding effect is affected, by setting the transmission mechanism, when the paper winding machine body 2 drives the paper leading roll 3 to rotate to wind the paper, the motor 16 is started, the motor 16 drives the threaded rod 17 to rotate, the external threads on the surface of the threaded rod 17 extrude the internal threads in the screw hole 19, so that the transmission block 18 and the stable block 20 move downward, the connecting plate 5 and the L-shaped plate 6 move downward synchronously with the transmission block 18, until the lower surface of the compression roller 9 contacts with both sides of the upper surface of the paper, the height of the compression roller 9 is adjusted to adjust the tension of the paper, with the limitation of the compression roller 9, both sides of the paper will not be upturned and deformed, and the winding effect of the paper is improved.

[0029] One side of stable block 20 is fixedly connected with dovetail sliding block 21, the inner wall of support frame 4 is provided with dovetail sliding groove 22 matched with dovetail sliding block 21.

[0031] Example two:

[0032] On the basis of embodiment one, the transmission mechanism in this embodiment can adjust the height of the compression roller 9, so that the lower surface of the compression roller 9 is in contact with the upper surface of the paper on both sides, thereby avoiding excessive tension causing the paper to deform and rise on both sides. However, considering the different widths of the paper, if the compression roller 9 cannot accurately press on both sides of the upper surface of the paper, the paper may still deform and rise. The positioning mechanism in this application includes a U-shaped frame 10 fixedly connected to the top of the L-shaped plate 6, a positioning column 11 arranged inside the U-shaped frame 10, the bottom of the positioning column 11 penetrating into the inside of the L-shaped plate 6, a plurality of positioning grooves 12 on the top of the connecting plate 5 for cooperation with the positioning column 11, a guide rod 13 fixedly connected to the top of the positioning column 11, the top of the guide rod 13 penetrating into the top of the U-shaped frame 10, a guide hole 14 on the top of the U-shaped frame 10 for cooperation with the guide rod 13, and two traction blocks 15 fixedly connected to the circumferential side of the positioning column 11 in a symmetrical manner.

[0033] In this embodiment, by pushing the traction block 15 upwards, the traction block 15 drives the positioning column 11 to move upwards under the limitation of the guide rod 13 and the guide hole 14, so that the positioning column 11 moves away from the inside of the positioning groove 12. At this time, the position of the L-shaped plate 6 can be moved, so that the two compression rollers 9 are respectively located on both sides of the upper surface of the paper. Then, the traction block 15 is loosened, and the elastic force generated by the spring 23 pushes the positioning column 11 to move downwards, so that the positioning column 11 enters the corresponding positioning groove 12 inside, completing the adjustment of the position of the compression roller 9, and making the positions of the two compression rollers 9 correspond to both sides of the upper surface of the paper.

[0039] The position of the L-shaped plate 6 can be moved by pushing the traction block 15 upward, the traction block 15 drives the positioning column 11 to move upward under the limitation of the guide rod 13 and the guide hole 14, so that the positioning column 11 is away from the inside of the positioning groove 12, at this time, the position of the L-shaped plate 6 can be moved, so that the two compression rollers 9 are located on the two sides of the upper surface of the paper, then the traction block 15 is loosened, the elastic force generated by the spring 23 pushes the positioning column 11 to move downward, so that the positioning column 11 enters the corresponding positioning groove 12, the position adjustment of the compression roller 9 is completed, and the positions of the two compression rollers 9 correspond to the two sides of the upper surface of the paper.
