Description
Technical field
The utility model relates to the shredder field, relates in particular to paper shredding cutters and blade in shredder.
Background technology
In daily life and work, people are leaked for fear of confidential data, usually use shredder that confidential document is ground into to paper scrap.
Shredder relies on paper shredding cutters as shown in Figure 1 to carry out shredded paper.In this paper shredding cutters, the first rotor 01 and the second rotor 02 are arranged side by side, blade 011 and comb tablet 012 all have been arranged alternately on the first rotor 01 and the second rotor 02, and the blade 011 on the first rotor 01 is corresponding with the comb tablet 012 on the second rotor 02, and blade 011 on the first rotor and the blade 011 on the second rotor 02 are staggered, and then realize shredded paper work by blade 011 and comb tablet 012 engagement.As shown in Figure 2, blade 011 is fit together and is formed by the first auxiliary-blade 011a and the second auxiliary-blade 011b.In the shredded paper process, paper scrap easily enters between the first auxiliary-blade 011a and the second auxiliary-blade 011b, and then affects the shredded paper effect.In addition, blade 011 easily deforms, and the blade on blade 011 is easy to wear, causes the service life of shredder short.
As fully visible, the blade shredded paper weak effect in existing paper shredding cutters, and easily deform, blade is easy to wear, and then causes the service life of paper shredding cutters short.
The utility model content
For solving existing paper shredding cutters shredded paper weak effect, blade is yielding, blade on blade is easy to wear, and then cause paper shredding cutters short problem in service life, the utility model proposes a kind of blade for shredding paper, the laminated structure that this blade is annular, be arranged at intervals with some cutting lugs on the outer rim of this blade, and be provided with blade on described cutting lug end; Be provided with the location lug on the inner edge of this blade.Such blade can not hidden paper, good crushing effect, and the blade on blade is not yielding, wearing and tearing, long service life.
Preferably, be provided with two blades on described cutting lug, and be provided with spacing convave trough between these two blades.Like this, while pulverizing paper, blade is stressed less, not yielding, long service life, and can further improve crushing effect,
Preferably, the number of described cutting lug is 24, and is uniformly distributed on the outer rim of described blade.Like this, paper can be ground into to paper scrap of uniform size, can further improve crushing effect.
Preferably, the thickness of described blade is 0.7-0.9mm.Further, the thickness of described blade is 0.8mm.Like this, paper can be ground into to width is the paper scrap of 1mm left and right, the security classification of having improved shredder.
Preferably, the both sides of described location lug are provided with detent, and the bottom land of this detent is arcuate structure.Like this, be convenient to blade is installed on cutter shaft, and, when blade is installed, blade and cutter shaft are difficult for sustaining damage.
The utility model blade for shredding paper can not hidden paper, good crushing effect, and blade is not yielding, wearing and tearing, long service life.Between two blades on cutting lug end, spacing convave trough is set, and makes to cut lug and be uniformly distributed on the blade outer rim, can further improve crushing effect.The thickness of blade is limited between 0.7-0.9mm, can improves the security classification of shredder.In lug both sides, location, the detent that bottom land is arcuate structure is set, can protects blade and cutter shaft.
The utility model also proposes a kind of paper shredding cutters, and the blade in this paper shredding cutters is above-mentioned any one blade.Preferably, V-shaped for the locating slot that described blade is installed on the cutter shaft of this paper shredding cutters, and extend to the other end from an end of described cutter shaft.Such paper shredding cutters can avoid blade to rotate around cutter shaft on cutter shaft, and good crushing effect, and security classification is high.
In addition, the utility model also proposes a kind of shredder, and this shredder is equipped with above-mentioned any one paper shredding cutters.Such shredder good crushing effect, and security classification is high.

Fig. 2 is the structural representation of the blade on the rotor in Fig. 1;
Fig. 3 is the structural representation of the utility model paper shredding cutters;
Fig. 4 is the perspective view of the blade in the utility model paper shredding cutters;
Fig. 5 is the perspective view of the cutter shaft in this practical paper shredding cutters.
The specific embodiment
As shown in Figure 3, the utility model paper shredding cutters comprises two rotors that are arranged side by side 1, and this rotor 1 comprises cutter shaft 11, some blade 12 and some comb tablets 13 as shown in Figure 4.Wherein, blade 12 is identical with the thickness of comb tablet 13, and blade 12 and comb tablet 13 alternately arrange on cutter shaft 11, and then make a blade 12 on rotor 1 corresponding with the comb tablet 13 on another rotor 1, to realize shredded paper work.
As shown in Figures 3 and 5, on the axial plane of the cutter shaft 11 in paper shredding cutters, be provided with locating slot 111, and this locating slot 111 is V-shaped on axial plane, and extends to the other end from an end of cutter shaft 11.Preferably, the groove at locating slot 111 notch places is along being projected on locating slot 111, and like this, outstanding groove, along blocking blade 12, avoids blade 12 to rotate around cutter shaft 11 on cutter shaft 11.
As shown in Figures 3 and 4, the blade in paper shredding cutters 12 is the annular laminated structure.Be arranged at intervals with some cutting lugs 121 on the outer rim of blade 12, and be provided with two through grinding the blade 1211 formed on the end of cutting lug 121, and be provided with spacing convave trough 1212 between these two blades 1211, separate with two blades 1211 that will cut on lug 121, and then improve the shredded paper effect.The thickness of blade 12 is 0.7-0.9mm, preferred 0.8mm, and like this, the width of the paper scrap that pulverizing can be obtained is controlled at the 1mm left and right, to improve shredder shredded paper effect, and then the security classification of improving shredder.Preferably, be provided with 24 cutting lugs 121 on the outer rim of blade 12.Certainly, also can be according to the size of the external diameter of blade and the quantity of the shredded paper effect adjustment cutting lug 121 that shredder will be satisfied.Preferably, 24 cutting lugs 121 that are positioned on the outer rim of blade 12 are evenly distributed.Like this, the paper scrap obtained after the shredder shredded paper is even.Be provided with the location lug 122 of rectangular configuration on the inner edge of blade 12.Like this, when blade 12 is arranged on cutter shaft 11, location lug 122 is stuck in locating slot 111, but blade 12 is fixed on cutter shaft 11, though and the rotation of cutter shaft 11 and rotating.Preferably, be provided with detent 1221 in the both sides of this location lug 122.Like this, be convenient to by blade 12 sheathed be stuck in while being installed on cutter shaft 11 the outstanding groove of locating slot 111 on cutter shaft 11 along on, and then avoid blade 12 to rock on cutter shaft 11.Preferably, the bottom land of detent 1221 is arcuate structure, like this, can avoid causing damage when being installed on cutter shaft 11 by blade 12.
The utility model also proposes a kind of shredder, and this shredder comprises above-mentioned paper shredding cutters.When using such shredder to carry out shredded paper work, while rotating under the driving of the motor in cutter shaft 11 shredders, its band cutting blade 12 rotates, thereby the paper cutting that will enter in cutter for paper grinder is broken into paper scrap.Due to the thickness of blade for shredding paper, between 0.7-0.9mm, the width of the paper scrap that the shredder shredded paper forms is in the 1mm left and right, and like this, people are difficult to obtain secure content from paper scrap, and security classification is higher.
