Paper shredder

Abstract

The invention provides a paper shredder. The paper shredder comprises a first paper shredding shaft and a second paper shredding shaft which are in running fit with each other for paper shredding, wherein a first paper cutting shaft and a second paper cutting shaft which are in running fit with each other are arranged at paper feeding ports of the first paper shredding shaft and the second paper shredding shaft, and a plurality of sets of paper cutting blades which are matched with each other for paper cutting are respectively arranged on the first paper cutting shaft and the second paper cutting shaft at intervals. After being fed into the paper feeding ports, the paper firstly passes through the first paper cutting shaft and the second paper cutting shaft, and is cut into a plurality of parts by the plurality of sets of paper cutting blades, and the cut paper is shredded. Through the cutting of the first paper cutting shaft and the second paper cutting shaft, a whole piece of paper is cut into a plurality of pieces which are cut respectively, so that the cutting resistance of the first paper shredding shaft and the second paper shredding shaft is decreased, and the radius of the paper shredding shafts can be set to be reduced, so that the using cost of the paper shredding shafts and the production cost of the paper shredder are lowered.

Description

technical field [0001] The present invention relates to the technical field of office equipment, and more specifically, relates to a paper shredder. Background technique [0002] The paper shredder consists of a set of rotating blades, a paper comb and a drive motor. The paper is fed from the middle of the interlocking blades and is divided into many small pieces of paper. [0003] When a traditional shredder shreds paper, it needs to shred the paper. Usually, the whole paper is directly sent to the paper inlet, and the shredding blade assembled on the shredder shaft rotates to shred and break the paper. The paper shredder directly shreds the whole paper, and the whole paper is directly fed into the shredder from one end for shredding. Since the fixing plate fixing the two shredding shafts is far away, the shafts are easy to bend when shredding, so it needs to be shredded. The paper shaft has a larger outer diameter so that it will not bend, and the shredder knife is requir...

AI Technical Summary

Problems solved by technology

The paper shredder directly shreds the whole paper, and the whole paper is directly fed into the shredder from one end for shredding. Since the fixing plate fixing the two shredding shafts is far away, the shafts are easy to bend when shredding, so it needs to be shredded. The paper shaft has a larger outer diameter so that it will not bend, and the shredder knife is required to provide greater shredding power, resulting in higher production costs for the shredder
