In this embodiment, by setting the fixing mechanism 2, the position of the paper can be fixed by the fixing mechanism 2 when the paper reaches the position of the crease, so as to prevent the position of the paper from shifting during the folding period, resulting in inaccurate crease position, and by the cooperation of the roller 19 and the telescopic rod 17, the roller 19 can flatten the paper, so as to prevent the inaccurate crease position caused by the bending and wrinkling of the paper, and the folding effect can be further improved.
[0028] Reference Figure 4 , a guide plate is provided on one side of the limit plate 10 and the top plate 11, and the rack 12 is meshed with the driving gear 9. The limit plate 10 and the top plate 11 are connected to the driving gear 9 through the rack 12. The guide plate is divided into an upper and lower layer, and the lower layer limits the movement of the limit plate 10. In this embodiment, by setting the guide plate, the position of the limit plate 10 and the top plate 11 can be prevented from being misaligned during movement, ensuring that the moving direction of the guide plate and the top block is correct and will not cause jamming. By setting the rack 12, the rack 12 is integrated with the limit plate 10 and the top plate 11 respectively, and the rack 12 is only on one side of the top plate 11, and the top plate 11 is sleeved on the outer surface of the gear, so that the driving gear 9 can drive the limit plate 10 and the top plate 11 to move toward each other, so that the limit plate 10 and the top plate 11 can achieve a clamping and limiting effect on the paper.
[0029] A knife groove 23 is provided at one end of the limiting mechanism 7. The knife groove 23 is detachable and replaceable. The folding angle of the paper can be adjusted through the cooperation between the knife groove 23 and the folding knife head 5.
[0030] The implementation principle of this embodiment is:
[0031] When in use, put the paper into the operating table 21, start the driving motor, and the output shaft of the driving motor drives the driving gear 9 to rotate. Because the driving gear 9 is engaged with the rack 12, the driving gear 9 drives the limiting plate 10 and the top plate 11 to move towards each other. The top plate 11 pushes the paper on the operating table 21 forward, and the limiting plate 10 drives the limiting wheel 13 to move in the direction of the paper to limit the horizontal position of the paper.

[0032] When the paper is bent and wrinkled, the fixed cylinder 16 is started, and the fixed cylinder 16 drives the telescopic rod 17 to move. The telescopic rod 17 drives the roller 19 to move forward through the bearing block 18. The roller 19 moves forward on the top of the paper. The roller 19 flattens the wrinkled and bent paper to prevent the crease position from being inaccurate due to the bending of the paper, further improving the folding effect. The driving cylinder 6 drives the lifting rod to move, and the lifting rod drives the folding knife head 5 to move downward. Through the cooperation of the folding knife head 5 and the knife groove 23, the paper reaches the required angle, so the device has certain practicality.
[0033] Compared with the prior art, the present invention has the following beneficial effects:
[0034] The adjustable folding mechanism of the folding machine can fix the position of the paper by setting a fixing mechanism 2 when the paper reaches the position of the crease, so as to prevent the position of the paper from shifting during the folding period, resulting in an inaccurate crease position. Moreover, through the cooperation of the roller 19 and the telescopic rod 17, the roller 19 can flatten the paper to prevent the inaccurate crease position caused by bending and wrinkling of the paper, thereby further improving the folding effect. By setting a limiting mechanism 7, the horizontal position of the paper can be limited, and the limiting wheel 13 can allow the paper to continue to move forward when it reaches the position.
[0035] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
