Description

Longitudinal and transverse cutting integrated paper shredder combined cutter
Technical Field
The invention belongs to the technical field of paper shredder accessories, and particularly relates to a combined cutter of a paper shredder with integrated longitudinal and transverse cutting.
Background
The paper shredder mainly cuts paper by two adjacent side-by-side knife rolls of a paper shredding mechanism, and each knife roll is integrally provided with a row of blades along the axial direction. In the same knife roller, a comb sheet is arranged between two blades so as to be tightly matched with the blades in the same row, and when two knife rollers are arranged in close proximity side by side, paper cutting can be realized by mutual meshing between the blades. In this process, the comb is relatively stationary, which serves as a space for supporting blades and for combing paper, and since the comb is generally a sheet-like member, its shape and contour have a large influence on the role of the comb, a shredder is a business machine that destroys confidential or private document materials by cutting. Some shredders can cut credit cards and compact discs in addition to paper materials. The shapes cut by the automatic paper shredder mainly comprise long strips, short strips, granules and the like. In general, the smaller the cut pieces, the lower the likelihood that someone else will piece together the content from the pieces. In order to enhance the security, the cutting direction should be perpendicular to the writing direction of the characters, and the fragments should be scattered and disturbed before being discarded, otherwise the documents cut by the paper shredder can be recovered through the effort, and the cutting principle of the paper shredder is that the blades or the cutters are arranged in a staggered way, and the paper is torn under the action of the power source. If the cutter or the blade is provided with the cutter point, the paper shredding effect is sectional or granular, if the cutter or the blade is not provided with the cutter point, the effect is strip, when the existing paper shredder is used for shredding paper, the main shredding mode is horizontal cutting or longitudinal cutting, and the problems that the shredding is not thorough, the cutting can be carried out only in one direction, the shredding effect is poor and the like exist.
