Description

technical field [0001] The invention relates to the field of office supplies machinery, in particular to a shredder paper feeding device with a protective cover. Background technique [0002] 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 shredding knife, the existing shredding methods include: granular, segmental, strip and so on.

Some offices have a large amount of data, and often need to process a lot of paper in a short period of time. The existing paper shredders are generally fed by the user by hand, or by an automatic paper feeding device, but now Some automatic paper feeding devices generally use rubber rollers to feed paper, which is prone to paper slippage, the paper feeding speed is slow, and it is impossible to feed a large amount of paper in a short time, and the paper is easy to roll up when feeding, causing paper jams and affecting work efficiency
