Abstract

The invention discloses a cutting-type paper shredding mechanism. The cutting-type paper shredding mechanism comprises two cutting-type paper shredding tools which are arranged oppositely, wherein each cutting-type paper shredding tool comprises a cutter shaft and a plurality of paper shredding blades which are installed at certain intervals or integrally formed on the cutter shaft; two sides of the tail end of a cutter body of each paper shredding blade are respectively provided with long cutting edges and short cutting edges with different lengths, and a long cutting edge of one cutting-type paper shredding tool and a short cutting edge of the other cutting-type paper shredding tool are mutually matched to shred paper, so that according to the invention, when paper is shredded, two cutting edges with different lengths are matched to cut paper, and meanwhile paper is cut open, and force is saved in paper shredding; on the other hand, when the two paper shredding cutter blades provided by the invention are matched to shred paper, because two cutting edges corresponding to opposite surfaces of two adjacent cutter blades are a long cutting edge and a short cutting edge with different lengths, when paper is shredded, paper shredded particles obliquely fall off between two adjacent cutter blades, and paper is difficult to clamp.

Description

technical field [0001] The invention relates to the field of knives, in particular to the field of shredding knives. Background technique [0002] With the rapid development of knowledge today, people's awareness of confidentiality is getting stronger and stronger. In daily life or work, there are often documents that need to be destroyed, so as to prevent others from obtaining the information recorded on the documents. Correspondingly, all kinds of discarded paper technical materials should be shredded before being thrown away as garbage. Different shredding methods are suitable for different occasions. If it is a general office occasion, you can choose segmental, granular, filamentary, or strip-like. But if it is used in some occasions that require high confidentiality, it must use foam. So at present, various paper shredders are widely used in offices. The paper shredding cutter of the paper shredder includes two oppositely arranged cutter shafts, and a number of shre...
