technical field

The invention relates to the technical field of paper shredder equipment, in particular to a double-crushing civil paper shredder.

Background technique

A shredder consists of a set of rotating blades, a 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 to achieve the purpose of confidentiality. The shredding method refers to the shape of paper shredded by a shredder knife after being processed by a shredder. According to the composition of the shredder knife, the existing shredding methods include: crushed, granular, segmental, foamy, strip, and silky.

At present, most paper shredders are set with a single set of hobs, which is not thorough enough to shred the paper. At the same time, most of the shredded paper strips are placed in an orderly manner, resulting in low confidentiality. Therefore, we propose a double shredding type for civilian use. Shredders are used to solve the above problems.
