Description
Technical field
It the utility model is related to a kind of cutter, and in particular to the cutter for paper grinder of circumferencial direction relative motion can be avoided.
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 directly to throw into dustbin in the past, but was presently not, shredder be for modern offices can not or
Scarce instrument, needed for the discarded file of need for confidentiality, confidential data, drawing, the waste paper of base friend's security information and paper etc.
The security article of safe handling is wanted, was destroyed in the past with hand, but this method was both dangerous, efficiency is again low, and compares expense
Power, some information carriers (such as CD, floppy disk etc.) especially for the modern times have not been just methods.
We are combed usual shredder by blade, the paper of one group of rotation, drive motor and reduction gearing form, paper
Open and be sent among the blade being mutually twisted, be 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 the metal gear of initial V belt translation, plastic gear, Chain conveyer till now
It is indispensable a kind of simple to be increasingly becoming office as a kind of privacy device for dynamic, high duty alloy gear drive, shredder
Device, being not only because it has function of keeping secret, is even more because it can provide a environment-protecting clean for modern offices
Ensure.
The cutter of shredder is the core entirely to work, although current cutter for paper grinder is consumer institute at present
Receive, but traditional cutter for paper grinder to be in actual use there are still having much room for improvement in place of inconvenience, such as knife be present
The problems such as piece occurs relative motion in circumferencial direction with cutter shaft and causes paperboard, and paper is not carefully enough broken, and cost is high.
Utility model content
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided can avoid circumferencial direction
The cutter for paper grinder of relative motion, it has smooth and sharp edge blade by setting, and cutter shaft is arranged into prism,
It can make paper is broken to obtain more thorough and avoid blade that relative motion occurs in circumferencial direction with cutter shaft.
The utility model is achieved through the following technical solutions：
The cutter for paper grinder of circumferencial direction relative motion, including cutter shaft and set of blades, the set of blades suit can be avoided
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 and the prism size of cutter shaft match, blade top is acute angle, and the center of the knife back is passed through in a side of acute angle.Due to
The cutter of shredder is constantly rotated to reach the purpose of shredded paper in use, if the centre bore of cutter shaft and blade set
For toroidal, after the interaction force between cutter shaft and blade wears the centre bore side of cutter shaft surface or blade,
Relative motion so occurs between blade meeting and cutter shaft, causes shredded paper not in time, if the paper for not having enough time crushing brought into
Shredder will result in paperboard, and the utility model is set due to cutter shaft is arranged into prism, and by the through hole at knife back center
For the polygonal hole to match with cutter shaft prism, even if wearing, will not also occur in circumferencial direction between blade and cutter shaft
Relative motion, so as to avoid the paper jam phenomenon during shredded paper；Secondly, it is acute angle by blade top, can be treated with fast-crushing
Shredded paper, efficiency high, action is fast, paper is crushed more thorough；In addition, every group of set of blades sets two panels blade, Ke Yizeng
The toughness of big every group of set of blades, because shredder rate request is not high, as long as selecting suitable blade material, it is possible to which satisfaction is
Energy shredded paper and can crushes the functional requirement of the hard materials such as CD, clip.
Further, the first positioning hole and the second positioning hole being provided through on the knife back of the blade.Set first
Positioning hole and the second positioning hole, it can not only be used to position when set of blades assembles, the weight of blade can also be mitigated, saved former
Material, reduce cost.
Further, the preceding surface of a piece of blade of every group of set of blades is bonded with the rear surface of another blade, and two panels
First positioning 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 the rear surface of chamfer plane and blade intersects at blade
Top.
Further, the thickness of the blade is identical with the knife back, and the front and rear surfaces of blade and the front and rear surfaces of the knife back point
It is not coplanar.
Further, the knife back and blade are formed in one structure.
Further, the blade of every piece of blade is using the center of the knife back as 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, the quantity of the blade of every piece of blade is 11.
The utility model compared with prior art, has the following advantages and advantages：1st, by the way that cutter shaft is arranged to
Prism, and the polygonal hole that the through hole at knife back center is arranged to match with cutter shaft prism, can avoid cutter from using
During it is caused abrasion make relative motion circumferentially occurs between blade and cutter shaft, so as to avoid paper from integrally bringing shredded paper into
Machine causes paper jam phenomenon；2nd, due to paper jam phenomenon has been reduced or avoided, operating efficiency can be improved and reduce maintenance cost；3rd, lead to
It is acute angle to cross blade top, can be with fast-crushing paper cutting, efficiency high, and action is fast, paper is crushed more thorough；4、
Blade and the knife back are formed in one structure, processing technology is simple, and die cost is low, so that the cost of shredder subtracts
It is few；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
Rule, processing is simple, and stress is good.
