The knife flywheel mechanism comprises an upper cutter shaft, a lower cutter shaft, an upper bush, upper round blades, a lower bush, lower round blades and key bars, wherein one end of the upper cutter shaft and one end of the lower cutter shaft are meshed together through a gear; and the other end of the lower cutter shaft is connected with a power mechanism. According to the cutter flywheel mechanism of the paper shredder disclosed by the invention, the upper round blades and the lower round blades of the same size are meshed together in a staggered mode, the structure is simple, the problem that a rotary blade type structure is low in adaptability can be completely solved, particularly the cutter is difficultly blocked in the process of shredding materials with large thickness and high toughness, and the shredded paper scraps are consistent in size.
Description
Technical field
The invention belongs to shredder field, be specifically related to a kind of kneader knife wheel mechanism.
Background technology
Shredder is comprised of one group of blade rotating, paper comb and CD-ROM drive motor.Paper is sent in the middle of the blade of mutual interlock, is divided into a lot of tiny scraps of paper, to reach secret object.Shredded paper mode refers to the shape after paper is shredded by paper shredding blade after shredder is processed.According to the building form of paper shredding blade, existing shredded paper mode has: broken shape, granular, section shape, foam shape, strip, thread etc.
Common printed product generally do not need just to destroy and can recycle, and relating to bill, ticket, paper class etc. has valency or secret printed matter must after first fragmentation, reclaim again.The type of existing shredder can be divided into two kinds according to serviceability to causing greatly function: the one, and small files destruction shredder; The 2nd, large scale industry shredder.The latter is mainly used in paper-making industry.As the manufacturing enterprise that has valency class and secret class printed document, there are a large amount of useless time printed matters and consumptive material to need broken destruction, there is on the one hand the inevitable demand of using shredder, face again inorganic optional awkward situation on the one hand, the shredder of above-mentioned two types is all not suitable for.
Existing shredder rotating blade crumbling method adaptability is poor, is mainly reflected in: the scraps of paper after, smashing are not of uniform size, can not all reach destruction dimensional requirement; Two, easy swaging clamp during broken thicker cost waster; Three, be easily wound around during broken thin, tough paper; Four, cannot crushing aluminum matter ps forme.
