Multi-segment slitting type paper shredder and paper shredding method

Abstract

The invention discloses a multi-segment slitting type paper shredder. The multi-segment slitting type paper shredder comprises a rack, N paper shredding mechanisms, a paper dividing mechanism, a paper guiding mechanism and a driving mechanism, wherein the N paper shredding mechanisms, the paper dividing mechanism, the paper guiding mechanism and the driving mechanism are mounted on the rack, and N is an integer which is equal to or greater than two; the paper dividing mechanism is used for dividing a piece of paper into N parts in the longitudinal direction of the paper; the paper guiding mechanism comprises N paper guiding channels, and the N paper parts obtained through division are conveyed to the N paper shredding mechanisms through the N paper guiding channels; and the driving mechanism is used for driving the paper shredding mechanisms and the paper dividing mechanism to act. According to the multi-segment slitting type paper shredder, cutter shafts of the paper shredding mechanisms can be made quite short, so that paper shredding cutters are made high in strength and low in cost; and the driving mechanism drives the short paper shredding cutters to rotate, so that labor is saved, consumption is reduced, impact force of the paper shredding cutters during paper feeding is reduced, the load power needing to be borne by the driving mechanism is reduced, and the service life of the paper shredder is prolonged. In addition, the invention discloses a corresponding multi-segment slitting type paper shredding method.

Description

technical field [0001] The invention relates to the field of paper shredders, in particular to a paper shredder and a paper shredding method for shredding paper in stages. Background technique [0002] With the rapid development of knowledge today, people's awareness of confidentiality is getting stronger and stronger. 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. Correspondingly, all kinds of discarded paper technical materials should be shredded before being thrown away as garbage. Different shredding methods are suitable for different occasions. If it is a general office occasion, you can choose segmental, granular, filamentary, or strip-like. But if it is used in some occasions that require high confidentiality, it must use foam. So at present, various paper shredders are widely used in offices. [0003] However, when the current paper shredder shreds paper...

Problems solved by technology

[0003] However, when the current shredder shreds paper, the paper guide channel in the shredder mechanism directly guides the paper into the shredder mechanism, and the driving mechanism needs to drive the shredder mechanism to cut the entire paper. When the amount of shredded paper is relatively large, it is necessary to The strength of the cutter shaft and blade in the shredding mechanism is required, which makes the cost of the shredder high, and when the paper is shredded (when paper is fed), due to the large impact force, the load power required by the driving mechanism is relatively large. Prone to failure and affect shredder life
