Technical Field

[0001] The utility model relates to the technical field of a cutter adjustment device for a paper cutter, in particular to a cutter adjustment structure for a paper cutter. Background Art

[0002] Paper cutter is a traditional product used to handle the paper cutting needs in the later stage of printing. It has developed from mechanical paper cutter to tape-controlled paper cutter, and then to microcomputer program control, color display, full image operation guided visual processing and computer-aided cutting external programming and editing of production data cutting system, which shortens production preparation time, improves cutting accuracy, reduces labor intensity and makes operation safer. The knife cutting mechanism of paper cutter is a part of paper cutter, which is used to cut paper.

[0003] The Chinese patent CN214352878U authorized and announced on December 8, 2020 discloses a paper cutter cutting mechanism that is easy to adjust, which includes a knife holder and multiple blades. The knife holder includes a lead screw and a stabilizing rod arranged in parallel, and multiple sliding knife seats are provided on the lead screw and the stabilizing rod. Multiple fixing nuts are provided on the lead screw. The fixing nuts and the sliding knife seats are arranged at intervals. The sliding knife seat is fixed on the lead screw through the fixing nuts at both ends. The upper part of the knife seat is provided with a first through hole and a second through hole. The lead screw and the stabilizing rod are respectively inserted into the first through hole and the second through hole. The bottom of the sliding knife seat is provided with a mounting groove, and the back of the blade is arranged in the mounting groove and fixed by a fixing mechanism. In the above application document, when the cutter cuts the paper, the impact force generated downward on the paper is likely to cause certain damage to the surface of the base. Long-term operation causes certain wear on the base and the cutter. At the same time, it is difficult to effectively position the paper when cutting the paper, and it is difficult to position and maintain the paper stably when cutting. Utility Model Content
