Office paper shredder with self-cleaning function

Abstract

The invention relates to the technical field of paper shredders, and discloses an office paper shredder with a self-cleaning function. The office paper shredder comprises a shredding shaft, wherein the outer side wall of the shredding shaft is fixedly connected with shredding blades, and one side of the shredding shaft is provided with a fixed seat; and the interior of the fixed seat is slidably connected with a transmission rack, one end of the transmission rack is fixedly connected with a transverse moving rod, and the outer side wall of the transmission rack is engaged with arc-shaped gears. The transverse moving rod drives the transmission rack to reciprocate, the transmission rack drives hinge rods on the arc-shaped gears to swing left and right, then the hinge rods drive semicircularplates on supporting seats to swing left and right, and brushes on the semicircular plates make contact with the shredding blades and rub against the shredding blades, so that paper fibers adhering to the shredding blades are brushed off, the purpose of automatic cleaning is achieved, and then the phenomenon that paper files are not completely cut due to the fact that the cutting effect of the blades is affected when the paper fibers are stacked to a certain degree is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of shredders, in particular to an office shredder with self-cleaning function. Background technique [0002] At present, in office activities, in order to keep paper documents confidential, a paper shredder is usually used to shred the paper documents. The paper shredder is composed of a group of rotating blades, a paper comb and a driving 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. [0003] Because paper documents have fibers, the cutting surface of the blade is easy to stick to paper fibers during the cutting process. When paper fibers...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an office paper shredder with self-cleaning function, capable of automatically cleaning the surface of the blade and blowing the paper fibers on the blade by airflow while the blade is working. It solves the problem that the existing shredders cannot automatically clean the blades during the working process, and need to stop working to clean them, and because the blades are closely arranged together, it is easy to appear dead angles during cleaning question
