Description
Technical field
The present invention relates to a kind of cutter, and in particular to a kind of shredded paper equipment based on shredder.
Background technology
With the development in epoch, commercial competition is more and more fierce, and the secrecy of daily data also becomes particularly important, and some are done
Official document part was all in the past directly to throw into dustbin, but was presently not, shredder be for modern offices can not or
Scarce instrument, the friend's security information of waste paper and paper discarded file, confidential data, drawing, base to(for) need for confidentiality etc. are needed
The security article of safe handling is wanted, was destroyed with hand in the past, but this method was both dangerous, and efficiency is again low, and compares expense
Power, has not been just method especially for some modern information carriers (such as CD, floppy disk etc.).
What our usual shredders were made up of one group of blade of rotation, paper comb, drive motor and reduction gearing, paper
The feeding from the middle of the blade being mutually twisted is opened, is divided into many tiny scraps of paper, to reach the purpose of secrecy, shredder is to now
The development course of several generations is experienced untill, is passed by initial V belt translation, plastic gear, Chain conveyer metal gear till now
Dynamic, high duty alloy gear drive, shredder has been increasingly becoming office indispensable a kind of simple as a kind of privacy device
Device, being not only because it has function of keeping secret, even more because it can provide a environment-protecting clean for modern offices
Ensure.
The cutter of shredder is the core of whole work, although current cutter for paper grinder is consumer institute at present
Receive, but traditional cutter for paper grinder has much room for improvement there are still inconvenience part in actual use, for example, there is knife
There is relative motion and cause paperboard in piece and cutter shaft, paper is not carefully enough broken in circumferencial direction, the problems such as high cost.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, there is provided a kind of shredded paper based on shredder
Equipment, it passes through to set has smooth and sharp edge blade, and cutter shaft is set into prism, paper can be made broken more
Plus thoroughly and avoid blade and cutter shaft that relative motion occurs in circumferencial direction.
The present invention is achieved through the following technical solutions：
A kind of shredded paper equipment based on shredder, including set of blades and cutter shaft, the set of blades is sleeved on cutter shaft, described
Cutter shaft is prism, and the set of blades includes multiple identical blades, and every piece of blade is provided with multiple blades and a knife back, knife
Sword is located on the excircle of the knife back, and the knife back is provided centrally with the polygonal hole for running through, the side number of polygonal hole and the stupefied number of cutter shaft
Identical, the size of polygonal hole matches with the prism size of cutter shaft, and blade top is acute angle, and a side of acute angle is by knife
Back of the body center.Because the cutter of shredder constantly rotates to reach the purpose of shredded paper in use, if by cutter shaft and blade
Centre bore be provided in round shape, when the interaction force between cutter shaft and blade makes the centre bore side of cutter shaft surface or blade
After wearing and tearing, then relative motion occurs between blade meeting and cutter shaft, shredded paper is caused not in time, if will not have enough time to crush
Paper bring shredder into and will result in paperboard, and the present invention is by cutter shaft due to being set to prism, and by the logical of knife back center
Hole is set to the polygonal hole matched with cutter shaft prism, even if wearing and tearing, also blade and knife will not occur in circumferencial direction
The relative motion of between centers, so as to avoid the paper jam phenomenon during shredded paper；In addition, be acute angle by blade top, can be quick
Crush paper cutting, efficiency high, action is fast, crush paper it is more thorough.
Further, the angle on the blade top is 33 degree.
Further, the preceding surface of the blade is provided with chamfering, and chamfer plane intersects at blade with the rear surface of blade
Top.
Further, the thickness of the blade is identical with the knife back, and the front and rear surfaces of blade are total to the front and rear surfaces of the knife back
Face.
Further, the blade and the knife back are formed in one structure.
Further, every piece of blade of blade with knife back center be the rounded array in the center of circle.
Further, the cutter shaft is hexagonal prism, and the centrally disposed polygonal hole of the knife back is hexagonal hole.
Further, every piece of blade quantity of blade is 11.
The present invention compared with prior art, has the following advantages and advantages：1st, it is set to prism by by cutter shaft
Body, and the polygonal hole that the through hole at knife back center is set to match with cutter shaft prism, can avoid cutter from using process
The abrasion of middle generation makes circumferentially relative motion between blade and cutter shaft, is made so as to avoid paper from integrally bringing shredder into
Into paper jam phenomenon；2nd, due to paper jam phenomenon has been reduced or avoided, operating efficiency can be improved and maintenance cost is reduced；3rd, by inciting somebody to action
Blade top is acute angle, can be with fast-crushing paper cutting, and efficiency high, action is fast, crush paper it is more thorough；4th, by knife
Sword and the knife back are formed in one structure, and processing technology is simple, and die cost is low, so that the cost of shredder is reduced；
5th, cutter shaft is set to hexagonal prism, the centrally disposed polygonal hole of the knife back is set to hexagonal hole so that cutter shaft and blade shapes are advised
Then, process simple, stress is good.
