AI Technical Summary
In a paper cutter, when manually placing palletized paper, it is difficult to ensure that the paper is parallel to the cutting knife, which easily leads to inclination of the cutting surface and affects the cutting quality. At the same time, the paper is not fixed well and it is easy to move due to cutting pulling power.
A guide structure of a paper cutter is designed, including a paper cutting table, a moving groove, a bidirectional screw, a moving seat, a guide plate and a servo motor. The servo motor drives the two-directional screw to rotate. The moving seat and the guide plate are used in combination to ensure that the paper remains parallel during cutting, and the paper is fixed through an extrusion mechanism to avoid movement due to cutting pull.
It effectively avoids the tilt and movement of the paper during cutting, improves the cutting quality and practicality, ensures that the paper is parallel to the cutter, and ensures the accuracy and consistency of cutting.

When cutting printed paper, paper cutters are needed. However, when using paper cutters to cut stacked paper, most of them are manually placed under the cutter. However, the cutting position of the paper is not convenient to ensure that it is parallel to the cutter, which easily causes the paper cutting surface to tilt, affecting the quality of paper cutting; and when the cutter cuts the paper, the paper is not easy to fix, and the paper will be pulled downward by the cutter, causing the paper to move. For this reason, we propose a guide structure for a paper cutter. Utility Model Content
