Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a paper cutter which is convenient for recycling waste scraps. Background Art

[0002] In the printing industry, paper needs to be cut before printing to ensure that the printed books and other finished products are neat and beautiful, and the printed layout is standardized. Generally, paper is cut by a paper cutter. There are different ways to recycle the waste paper after cutting.

[0003] According to a disclosed efficient paper cutter dust removal mechanism (publication number: CN 209335691 U3), in the paper cutter in the above application, dust removal mechanisms are symmetrically provided on both side walls of the cutting frame, and the dust removal mechanism includes a dust removal duct and a fan with a filter cartridge, one end of the dust removal duct opens on the corresponding inner side wall of the cutting frame, and the other end of the dust removal duct penetrates the corresponding side wall of the cutting frame and is connected to the corresponding fan. The fine dust generated during the paper cutting process can be captured by the dust removal ducts on both sides after entering the air, making it difficult for the fine dust to affect the air quality in the workshop, thereby effectively protecting the workshop environment.

[0004] However, in actual use of the above equipment, when the paper cutter cuts paper, sometimes not only waste scraps but also large pieces of paper are cut off. The exhaust fan nozzle cannot suck and clean such paper, which may cause the dust removal mechanism to be unable to clean the large pieces of paper, affecting the paper cutting efficiency of the paper cutter. In view of this, we propose a paper cutter that is easy to recycle waste scraps. Utility Model Content
