Description

Technical Field

[0001] The present application relates to the field of paper cutters, and in particular to a paper pressing device of a paper cutter. Background Art

[0002] A paper cutter is a mechanical device used to cut paper or other paper materials. They are commonly used in various occasions, including offices, printing plants, packaging industries, etc., to cut paper into the required size or shape. Paper cutters can be manually operated or automated. The specific models and functions will vary, but the basic principle is to cut the paper with a blade or knife. Since the stacked paper is in a loose state as a whole, it needs to be pressed before cutting, and the paper cutting operation is performed after the paper is compacted.

[0003] During the paper pressing operation, pressure is generally applied to the upper surface of the stacked paper so that the paper is pressed against each other tightly. However, the stacked paper has a certain height. During the pressing process, the paper may have a certain positional offset when moving, which in turn causes the stacked paper to tilt as a whole. This causes a certain degree of accuracy deviation in the paper after compaction and cutting, reducing the overall cutting effect of the paper after paper pressing.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the stacked paper has the defect of being tilted due to position deviation during the pressing process, and therefore proposes a paper pressing device for a paper cutter to solve the above-mentioned problem.
