Description
Technical field
The present invention relates to a kind of cutter, and in particular to be prevented from the cutter for paper grinder of circumferencial direction relative motion.
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 be prevented from circumferencial direction relative
The cutter for paper grinder of motion, it passes through to set has smooth and sharp edge blade, and cutter shaft is set into prism, can be with
Make paper broken more thoroughly and avoid blade and cutter shaft that relative motion occurs in circumferencial direction.
The present invention is achieved through the following technical solutions：
It is prevented from the cutter for paper grinder of circumferencial direction relative motion, including cutter shaft and set of blades, the set of blades suit
On cutter shaft, the cutter shaft is prism, and the quantity of the set of blades is multigroup, and the spacing between every two groups of set of blades is identical, often
Group set of blades includes two panels identical blade, and every piece of blade is provided with a knife back and multiple blades, and blade is located at the outer of the knife back
On circumference, the polygonal hole for being provided centrally with running through of the knife back, the side number of polygonal hole is identical with the stupefied number of cutter shaft, polygonal hole
Size match with the prism size of cutter shaft, blade top is acute angle, a side of acute angle by the knife back center.Due to
The cutter of shredder constantly rotates to reach the purpose of shredded paper in use, if the centre bore of cutter shaft and blade set
It is toroidal, after the interaction force between cutter shaft and blade makes the centre bore side of cutter shaft surface or blade wear and tear,
So there is relative motion between blade meeting and cutter shaft, cause shredded paper not in time, if the paper for not having enough time to crush brought into
Shredder will result in paperboard, and the present invention by cutter shaft due to being set to prism, and by the through hole at knife back center be set to
The polygonal hole that cutter shaft prism matches, even if wearing and tearing, also will not occur blade relative between cutter shaft in circumferencial direction
Motion, so as to avoid the paper jam phenomenon during shredded paper；Secondly, it is acute angle by blade top, shredded paper can be treated with fast-crushing
, efficiency high, action is fast, crush paper it is more thorough；In addition, every group of set of blades sets two panels blade, can increase every
The toughness of group set of blades, because shredder rate request is not high, as long as selecting suitable blade material, it is possible to which satisfaction can be broken
Paper can crush the functional requirement of the hard materials such as CD, clip again.
Further, the first location hole and the second location hole being provided through on the knife back of the blade.Set first
Location hole and the second location hole, can not only be used to position when set of blades is assembled, and can also mitigate the weight of blade, save former
Material, reduces cost.
Further, every group of preceding surface of a piece of blade of set of blades is fitted with the rear surface of another blade, and two panels
First location hole of blade overlaps.
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 divided with the front and rear surfaces of the knife back
It is not coplanar.
Further, the knife back and blade are formed in one structure.
Further, every piece of blade of blade with the center of the knife back 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 quantity of the blade 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.
