The existing cutting devices for paper production have inconvenience in adjusting the distance between cutting knives and tightening the paper. The scope of use is limited, and there is a lack of a tightening structure for paper.
By introducing a bidirectional threaded rod and a sliding block into the cutting mechanism, the first driving motor is used to drive the bidirectional threaded rod to rotate, causing the sliding block to move relative to each other or in opposite directions, thereby adjusting the distance between the cutting knives. At the same time, the paper guide mechanism adopts an electro-hydraulic rod, spring and roller structure. The second drive motor drives the active roller to rotate, and cooperates with the spring and guide rod to guide and tighten the paper.
It realizes the flexible adjustment of the distance between the cutting knives to adapt to different cutting needs, and improves the cutting accuracy through the tensioning effect of the paper guide mechanism.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-4 , the utility model provides a technical solution:
[0024] A cutting device for paper production, comprising a base 1, a fixed frame 2 is fixedly installed at the center of the surface of the base 1, a cutting mechanism 3 for cutting paper is installed on the inner top of the fixed frame 2, and paper guide mechanisms 4 for tightening and guiding paper are arranged on both sides of the fixed frame 2 and the cutting mechanism 3;
[0025] The cutting mechanism 3 includes a bidirectional threaded rod 31, which is rotatably installed on the inner walls of both sides of the fixed frame 2, and one end of the bidirectional threaded rod 31 passes through the fixed frame 2 and is fixedly connected to a first driving motor 32, and the outer walls at both ends of the bidirectional threaded rod 31 are threadedly connected to sliding blocks 33, and an electric push rod 34 is fixedly installed at the bottom of the sliding block 33, and a cutting knife 36 is installed at the bottom of the piston rod of the electric push rod 34, so that the bidirectional threaded rod 31 can be driven to rotate by the first driving motor 32, so that the sliding blocks 33 threadedly connected to the outer walls at both ends of the bidirectional threaded rod 31 can move relative to or oppositely, thereby adjusting the distance between the cutting knives 36 at the bottom of the two groups of sliding blocks 33.
[0026] The paper guide mechanism 4 includes an electric hydraulic rod 41, which is fixedly installed on the top of the fixed frame 2. One end of the piston rod of the electric hydraulic rod 41 penetrates the fixed frame 2 and is fixedly connected to a mounting plate 42. A plurality of groups of springs 43 are fixedly installed at the bottom of the mounting plate 42 at equal intervals. A mounting frame 44 is fixedly connected to the bottom of the plurality of groups of springs 43. A driven roller 45 is rotatably installed inside the mounting frame 44. An active roller 46 is installed directly below the driven roller 45 on the fixed frame 2. The driven roller 45 and the active roller 46 are arranged correspondingly up and down, so that the driven roller 45 at the bottom of the mounting plate 42 can be driven to move toward the active roller 46 by the extension and retraction of the piston rod of the electric hydraulic rod 41, so that the driven roller 45 contacts the active roller 46.
[0027] The active roller 46 is rotatably mounted on the inner walls of both sides of the fixing frame 2 , and one end of the active roller 46 passes through the fixing frame 2 and is fixedly connected to a second drive motor 47 , so that the active roller 46 can be driven by the second drive motor 47 to rotate and cooperate with the driven roller 45 .

At the same time, several groups of springs 43 and two groups of guide rods 48 at the bottom of the mounting plate 42 cooperate to make the driven roller 45 have a squeezing effect on the paper, thereby playing a guiding and tightening role when cutting the edge materials on both sides of the paper, which can improve the cutting accuracy.
