Automatic paper feeding structure of shredder

Abstract

The invention discloses an automatic paper feeding structure of a shredder, which overcomes the technical defect that a paper twisting wheel of a conventional automatic paper feeding structure skids on a waste paper file to fail to twist the waste paper file and finish automatic paper feeding. The adopted scheme is that: the automatic paper feeding structure comprises a group of paper twisting wheels, a paper supporting board and a control spring, wherein the group of paper twisting wheels are axially and uniformly distributed on a paper twisting shaft which is fixed on a frame; the radial end face of each paper twisting wheel is of a cam shape; the paper twisting wheels 1 are in movable contact connection with the paper supporting board 2 with an adjustable contact gap; the paper supporting board is fixed on the frame through a supporting shaft; and the control spring is connected with the frame and the paper feeding end of the paper supporting board to form the movable connection of the paper supporting board which can swing around the supporting shaft under the action of the control spring. The automatic paper feeding structure has the advantages of simple structure, high practicality, safety, reliability, low cost and the like.

Description

technical field [0001] The invention relates to an office equipment, in particular to a paper shredder, in particular to an automatic paper feeding structure of the paper shredder. Background technique [0002] A paper shredder is a commonly used office equipment used to shred waste paper documents. Due to the strengthening of people's awareness of information security, the application of paper shredders has increasingly become a necessary equipment for office work. In daily work, when using a paper shredder to shred documents, the blade assembly of the paper shredder rotates quickly to cut paper. In order to increase the efficiency of paper shredding, the existing paper shredders began to increase the automatic paper feeding structure. The existing automatic paper feeding structure uses the circular paper pickup wheel to directly rub against the shredded waste paper documents, and the circular paper pickup wheel and the shredded waste paper documents are directly rubbed. ...

Problems solved by technology

[0004] In order to overcome the technical defect that the pickup roller slips on the waste paper files and cannot rub the waste paper files, and cannot complete automatic paper feeding, the present invention designs an automatic paper feeding structure for a paper shredder. By changing the shape and support of the pickup roller The change of the relative position of the cardboard changes the rubbing position of the pickup roller against the waste paper document and the feeding angle of the waste paper document, so as to overcome the slippage of the pickup roller on the waste paper document
