Description

technical field [0001] The invention belongs to the field of shredders, in particular to an electric shredder and a paper shredding method for the electric shredder. Background technique [0002] A paper shredder is a daily office item that can quickly shred confidential documents. At present, the shredding methods of paper shredders can be divided into shredding from the top of the upper cover and shredding from the bottom of the upper cover; It is set on the upper part of the upper cover, and the paper feed roller is set under the upper cover. The pressure plate supports the paper against the paper feed roller, and the paper feed roller sends the paper to be shredded to the shredder roller; the method of shredding paper from the bottom of the upper cover, such as China Patent No. 200820151690.0 discloses a paper shredder. The cardboard is arranged at the lower part of the upper cover, and the paper is folded in half to shred the paper. The disadvantage is that the paper t...

Problems solved by technology

At present, the shredding methods of paper shredders can be divided into shredding from the top of the upper cover and shredding from the bottom of the upper cover; It is set on the upper part of the upper cover, and the paper feed roller is set under the upper cover. The pressure plate holds the paper against the paper feed roller, and the paper feed roller sends the paper to be shredded to the shredder roller; the method of shredding paper from the bottom of the upper cover, such as China Patent No. 200820151690.0 discloses a paper shredder. The paper support board is set at the lower part of the upper cover, and the paper is shredded after being folded in half. The disadvantage is that the paper to be shredded cannot be put in at any time.

U.S. Patent Nos. US20060430121 and US20040866145 respectively disclose a paper shredder pallet capable of folding and shredding paper and a paper shredder capable of folding paper in half. At both ends of the paper mouth, the place where the shredded paper is folded in half is the middle of the paper. The disadvantage is that the second paper can only be shredded after one paper is shredded.

[0003] From the way of shredding paper under the upper cover, how to fold and shred multiple sheets of paper in half, and add paper to be shredded at any time, so as to further improve shredding efficiency and save energy, the current technology still has inconveniences and defects, and further improvement is urgently needed
