At the same time, the mounting plate 14 is connected to the first driving component 15 for adjusting the upper circular knife. The upper circular knife 13 is connected to a first adjusting component 16 for adjusting the upper and lower positions, the first adjusting component 16 is one of a cylinder, a hydraulic cylinder or an electric telescopic rod, the first adjusting component 16 is connected to a second adjusting component 17 for adjusting the left and right positions of the upper circular knife 13, the second adjusting component 17 is a slider rail adjusting component, the upper and lower positions of the upper circular knife 12 can be adjusted by the first adjusting component 16, and the left and right positions of the upper circular knife 12 can be adjusted by the second adjusting component 17, so as to adjust the upper circular knife 13 to a suitable position, thereby effectively cutting the paper.

The lower traction roller 22 is connected to a second driving component 23 for driving the lower traction roller 22 to rotate. The second driving component 23 is a synchronous belt driving component. The lower traction roller 22 can be driven to rotate by the second driving component 23. The paper can be pulled and transported between the upper traction roller 21 and the lower traction roller 22. At the same time, the outer wall of the upper traction roller 21 is provided with an anti-slip groove. At the same time, the anti-slip groove can increase the friction between the upper traction roller 21 and the paper to prevent the paper from sliding between the upper traction roller 21 and the lower traction roller 22, thereby effectively pulling the paper.

[0024] In this embodiment, the cross-cutting mechanism 3 includes an upper cross-cutting roller 31 and a lower cross-cutting roller 32 arranged below the upper cross-cutting roller 31.

The paper after longitudinal cutting and transverse cutting can be output through the conveyor belt 41, and the rear end of the front conveyor belt 41 is higher than the front end of the rear conveyor belt 41. When the conveyor belt 41 is conveying the cut paper, the above design can make a certain height difference between the tail of the upper paper and the head of the lower paper, so as to avoid the tail of the upper paper blocking the head of the lower paper, thereby avoiding affecting the conveying of the lower paper. At the same time, a guide roller 42 is installed above the conveyor belt 41, and a plurality of guide wheels 43 are equidistantly installed on the guide roller 42. The paper conveyed on the conveyor belt 41 can be pressed by the guide wheel 43, so that the paper can be smoothly conveyed on the conveyor belt 41, and the paper can be prevented from flying when being conveyed on the conveyor belt 41.

The cut paper can be conveyed by the conveying mechanism 4 and fall onto the lifting plate 53 for collection. When more and more paper is collected on the lifting plate 53, the height of the paper continues to increase. At the same time, the fourth driving component 54 drives the lifting plate 53 to slowly descend to stack and collect the paper. Side baffles 55 are provided on the left and right sides above the lifting plate 53. When the paper falls on the lifting plate 53, the two side baffles 55 can block the paper from the left and right sides so that the paper can fall on the lifting plate 53. The two side baffles 55

[0027] The third adjusting assembly 56 is respectively connected to the third adjusting assembly 56 for adjusting the left and right positions of the two side baffles 55, the third adjusting assembly 56 is a slide rail slider adjusting assembly, the third adjusting assembly 56 is a slider slide rail adjusting assembly, the third adjusting assembly 56 is connected to the fourth adjusting assembly 57 for adjusting the front and rear positions of the two side baffles 55, the fourth adjusting assembly 57 is a slider slide rail adjusting assembly, the left and right positions of the two side baffles 55 can be adjusted by the third adjusting assembly 56, and the front and rear positions of the two side baffles 55 can be adjusted by the fourth adjusting assembly 57 The rear position of the rear baffle 58 can be adjusted so that the two side baffles 55 can effectively block the paper from the left and right sides. At the same time, a rear baffle 58 is provided above the lifting plate 54. When the paper falls on the lifting plate 53, the rear baffle 58 can block the paper from the rear so that the paper can fall onto the lifting plate 53. The rear baffle 58 is connected to a fifth adjusting component 59 for adjusting the front and rear position of the rear baffle 28. The front and rear position of the rear baffle 58 can be adjusted by the fifth adjusting component 59, so that the rear baffle 58 can effectively block the paper from the rear.

When in use, the paper can be wound around the lower recurve roller 62, the intermediate recurve roller 63 and the upper recurve roller 61 in sequence, and the bent paper can be straightened, so that the paper can be better cut. The intermediate recurve roller 63 is connected to a sixth adjustment component 64 for adjusting the front and rear position of the intermediate recurve roller 63. The fourth adjustment component 64 is a screw adjustment component. The relative position between the intermediate recurve roller 63 and the upper recurve roller 61 and the upper recurve roller 62 can be adjusted through the sixth adjustment component 64, so that the strength of the recurve can be adjusted according to the thickness of the paper.

[0029] The specific principle is that when the paper is cut, the paper can be pulled and transported by the traction mechanism 2. When the paper is transported to the recurving mechanism 6, the bent paper can be straightened by the recurving mechanism 6. The straightened paper can be cut longitudinally by the longitudinal cutting mechanism 1. The paper after longitudinal cutting can be cut transversely by the transverse cutting mechanism 3.
