Chain Knife Shredder with Single Cut Longitudinal Shredder

Abstract

The invention discloses an interlink knife paper shredder with single-cut longitudinal paper shredding mechanisms, which comprises a rack, a first paper shredding mechanism, a second paper shredding mechanism and a driving mechanism, wherein the first paper shredding mechanism, the second paper shredding mechanism and the driving mechanism are arranged on the rack; the first paper shredding mechanism is a single-cut longitudinal paper shredding mechanism, the second paper shredding mechanism is a transverse paper shredding mechanism or a single-cut longitudinal paper shredding mechanism, a paper shredding channel of the first paper shredding mechanism and a paper shredding channel of the second paper shredding mechanism are communicated and carry out paper shredding sequentially, the single-cut longitudinal paper shredding mechanism comprises two oppositely-arranged unilateral paper shredding knives, each unilateral paper shredding knife comprises a knife shaft and a plurality of unilateral cutting edges, the plurality of unilateral cutting edges are wound around the knife shaft and axially distributed along the knife shaft, and only one side and same side of the plurality of unilateral cutting edges are provided with a knife edge. Therefore, the interlink knife paper shredder disclosed by the invention carry out paper shredding by using two sets of paper shredding mechanisms without knife points; and the interlink knife paper shredder is simple in structure, convenient for paper shredding, labor-saving, easy to maintain, and long in service life.

Description

technical field [0001] The invention relates to the field of paper shredding, in particular to a chain knife shredder which uses two sets of shredding mechanisms to sequentially cut paper. Background technique [0002] At present, in daily life or work, there are often documents that need to be destroyed, so as to prevent others from obtaining the information recorded on the documents. The paper shredder mainly uses relatively rotating shredding cutters to cut waste paper into longitudinal strips or shreds. refer to figure 1 The traditional shredding mechanism 100 includes two shredding knives 61, 62 arranged oppositely, and the two shredding knives 61, 62 are engaged with each other. Shredding blades 612 , 622 protrude from the cutter shafts 611 , 621 . Both sides of the shredding blades 612 , 622 have knife edges, and the shredding blades 612 , 622 are opposite to each other in the gap between the shredding blades 622 , 612 . When shredding paper, the cutter shafts 611,...

AI Technical Summary

Problems solved by technology

To sum up, the traditional shredding mechanism is extremely labor-intensive and wastes energy when cutting paper, and it is inconvenient to leave the paper, which is easy to jam

[0003] Furthermore, when the traditional shredding mechanism cuts paper, in order to cut the paper into shreds, the shredding blade must be provided with several knife points, and the processing of the knife points makes it necessary to use a stamping process when manufacturing such shredding knives. Or shovel out the knife tip after the blade processing is completed, not only the process is complicated and the cost is high, but also in the traditional mechanism, after the two shredding knives cut paper for a long time and cause wear, a new shredding knife must be replaced, the service life is short, and the cost is high
