Abstract

The invention discloses a paper shredder combination cutter integrating vertical and horizontal cutting, which comprises two vertical and parallel fixed frames, the two ends of the cutter shaft are respectively connected to the fixed frames in rotation, and a plurality of longitudinal cutter shafts are respectively arranged on the cutter shaft. The two ends of the blade and the fixed scissors are respectively fixed on the fixed frame, and the movable scissors are located at the upper end of the fixed scissors. The driving motor drives the driving sprocket to pull the first driven sprocket or the second driven sprocket to rotate, and the first driven sprocket Drive two intermeshed gears to mesh with each other; the second driven sprocket drives the disc to rotate, the disc drives the slider to reciprocate left and right, and the slider and push rod drive the fixed scissors to reciprocate left and right on the movable scissors. The present invention cuts the paper longitudinally through the mutual cooperation of the cutter shaft and the longitudinal blades, and cuts the paper into long strips. Then, on the basis of the longitudinal cutting of the paper, under the shearing action of the moving scissors and the fixed scissors, the lateral Cut again, and the degree of fragments can be adjusted.

Description

technical field

[0001] The invention belongs to the technical field of paper shredder accessories, and in particular relates to a paper shredder combination cutter integrating vertical and horizontal cutting. Background technique

[0002] The shredder mainly cuts paper by two adjacent knife rollers of its shredding mechanism, and each knife roller is integrally equipped with a row of blades along its axial direction. In the same knife roll, a comb is installed between the two blades so that the blades in the same row are closely matched. When two such knife rolls are arranged side by side, the paper can be cut through the mutual engagement between the blades. In this process, the comb piece is relatively static, and it plays the role of supporting the blade and combing the paper activity space. Since the comb piece is generally a sheet-like piece, its shape and contour have a greater effect on it. A shredder is a business machine that destroys confidential or privacy-relate...
