[0029] Two sets of positioning plates 3 are respectively installed on one side wall of the two sets of support plates 2;

[0030] Paper roller 4 is mounted on the side walls of the two sets of positioning plates 3;

[0031] Cutting blade 5 is located on the other side above the base plate 1;

[0032] The pressing assembly is used to press and fix the cut paper and is set on two sets of support plates 2. The pressing assembly is a roller rotation pressing and limiting structure. The pressing assembly includes a fixing plate 6, which is set on the side wall of the two sets of support plates 2.

[0033] The pressing assembly also includes two sets of fixing blocks 8. The two sets of fixing blocks 8 are disposed on one side of the upper end face of the fixing plate 6. A set of support rods 9 are disposed on one side wall of each of the two sets of fixing blocks 8. A set of connecting blocks 10 is disposed at one end of each of the two sets of support rods 9. A set of brackets 11 is disposed on the lower end face of each of the two sets of connecting blocks 10. A set of fixing frames 12 is disposed on the lower end face of each of the two sets of fixing frames 11. A set of pressing rollers 13 is disposed on the inner wall of each of the two sets of fixing frames 12.

[0034] Specifically, during use, the paper on the paper roller 4 is passed through two sets of feeding rollers 38, between the fixed plate 6 and the pressing plate 7, and below the two sets of pressing rollers 13. Through the pressing assembly, the pressing plate 7 and the two sets of pressing rollers 13 can press the paper. Then, the drive motor 14 is started, and the drive motor 14 drives the cutting blade 5 to move up and down, so that the cutting blade 5 can cut the pressed paper. This avoids the paper moving during cutting, which would prevent the cutting blade 5 from cutting the paper at the accurate position, thus reducing the quality of paper cutting and improving the efficiency of paper cutting.

[0035] like Figures 1-5As shown, a base plate 40 is provided on the side wall of a set of support plates 2. A drive motor 14 is provided on the side wall of the base plate 40.

The other end of the hinge rod 16 is hinged to a second rotating rod 17. The second rotating rod 17 is rotatably connected to the side wall of another set of support plates 2. A first bevel gear 18 is provided on the outer wall of the second rotating rod 17. A second bevel gear 19 is meshed on one side of the base plate 1. A rotating shaft 20 is mounted on the side wall of the second bevel gear 19. The rotating shaft 20 is rotatably mounted on a support frame 21, which is connected to the upper surface of the base plate 1. The other end of the rotating shaft 20 is connected to a rotating plate 22. A slider 23 is mounted on the upper side wall of one side wall of the rotating plate 22. The slider 23 is slidably mounted on the inner wall of a slide groove 24, which is mounted on the side wall of a lifting member 25. The lifting member 25 is slidably mounted on the outer side of two sets of slide rods 26.

A mounting plate 28 is set on one side of the two sets of support blocks 27, and the lower end of the mounting plate 28 is set on the upper end of the base plate 1. A connecting rod structure 29 is connected to one side of the lifting component 25, and the connecting rod structure 29 is connected to the cutting blade 5. The drive motor 14 is started, and the drive motor 14 drives the first rotating rod 15 to rotate. The first rotating rod 15 drives the second rotating rod 17 to rotate through the hinge rod 16. The second rotating rod 17 drives the rotating shaft 20 to rotate through the first bevel gear 18 and the second bevel gear 19. The rotating shaft 20 drives the slider 23 to slide inside the slide groove 24 through the rotating plate 22, so that the lifting component 25 slides downward outside the two sets of sliding rods 26, and drives the cutting blade 5 to cut the paper through the connecting rod structure 29. Then the drive motor 14 is started in reverse to reset the cutting blade 5, which facilitates reciprocating cutting of the paper.

When the first rotating rod 15 rotates, it can drive the second gear 31 to rotate through the first gear 30. The second gear 31 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the circular plate 33 to rotate. The circular plate 33 drives the driving component 35 to slide inside a set of driving grooves 36 through the driving rod 34, thereby driving the driving turntable 37 to rotate. The driving turntable 37 drives the feeding roller 38 to rotate, thus conveying the paper for easy cutting by the cutting blade 5. A collection box 39 is provided on one side of the base plate 1 to facilitate the collection of the cut paper.

[0037] The above embodiment discloses an automated paper cutting device. In use, paper from the paper roller 4 is passed through two sets of feeding rollers 38, between the fixed plate 6 and the pressing plate 7, and below the two sets of pressing rollers 13. Then, the drive motor 14 is started, driving the first rotating rod 15 to rotate. The first rotating rod 15 drives the second rotating rod 17 to rotate via the hinge rod 16. The second rotating rod 17 drives the rotating shaft 20 to rotate via the first bevel gear 18 and the second bevel gear 19. The rotating shaft 20 drives the slider 23 to slide inside the slide groove 24 via the rotating plate 22, causing the lifting member 25 to slide downwards outside the two sets of slide rods 26. The rod structure 29 drives the cutting blade 5 to cut the paper, and then the drive motor 14 is started in reverse to reset the cutting blade 5. When the first rotating rod 15 rotates, it can drive the second gear 31 to rotate through the first gear 30. The second gear 31 drives the rotating rod 32 to rotate. The rotating rod 32 drives the circular plate 33 to rotate. The circular plate 33 drives the driving component 35 to slide inside a set of driving grooves 36 through the driving rod 34, thereby driving the driving turntable 37 to rotate. The driving turntable 37 drives the feeding roller 38 to rotate, thereby conveying and flattening the paper, which is convenient for the cutting blade 5 to cut.
