Description
Technical field
The utility model relates to a kind of blade for shredding paper, relates in particular to a kind of blade for shredding paper of realizing high strength chopping, life-span length, saving material.
Background technology
In enterprise office, the paper that much was used and cancelled owing to the data of top record is a corporate secret, need paper be carried out pulverization process in order to prevent the data that other people obtain on the file to be put down in writing, thereby shredder arises at the historic moment.Traditional shredder generally comprises two cutter shafts and is fixed on some to blade for shredding paper on the cutter shaft.During shredded paper, drive a series of gears by motor and transfer out than the slow-speed of revolution, to cutter shaft two cutter shafts rotated than high pulling torque, when paper passes between the cutter shaft of two rotations, two cutter shafts extruding paper, thus waste paper is cut into thin paper slip or particle.
In order to make the intensity of blade for shredding paper enough; Blade for shredding paper comprises two blade monomers; Each said blade monomer comprises blade, is located at the installing hole at said blade center and the edge of a knife that is positioned at said blade periphery; Said blade monomer is extended with point of a knife along its edge of a knife, the blade correspondence of two blade monomers fit together and two said blade monomers on position of tool tip relative.Yet because above-mentioned blade monomer is directly to be suppressed by solid sheet metal to form, the blade for shredding paper of processing is waste material too.
In order to save material; Prior art personnel have worked out a kind of hollow blade for shredding paper; With reference to utility model patent CN200620057862.9 (a kind of kneader bar that has salient point), and kneader bar pastes by two blade monomers back of the body and forms, and two blade monomers have two or more salient points next by punch forming respectively on the plane that the back of the body pastes; Salient point correspondence on the blade monomer is close together, and forms the big space between the blade.Yet this blade for shredding paper fits together near the several salient points on it, and intensity difference can only be used for short, easy deformation of cutting a small amount of paper and life-span; On the other hand because the centre of this type blade for shredding paper has big space, thin paper slip after the cutting or particle can the cavity of rotating clamp between two blade monomers along with blade for shredding paper in, hinder shredded paper work.
Therefore, be badly in need of a kind of blade for shredding paper that overcomes the problems referred to above.
The utility model content
The purpose of the utility model is to provide a kind of blade for shredding paper of realizing high strength chopping, life-span length, saving material.
Another purpose of the utility model is to provide a kind of blade for shredding paper monomer of realizing high strength chopping, life-span length, saving material.
For on realizing purpose is arranged; The utility model provides a kind of blade for shredding paper; Formed by the relative applying of two blade monomers, each said blade monomer comprises blade, is located at the installing hole at said blade center and the point of a knife that stretches out and form along said blade periphery, and the medial surface of said blade is provided with the division wall of some pits and the said pit of formation separation; Said division wall interconnects, and said pit is covered with said blade and makes the medial surface of said blade be netted or cellular.
Preferably, triangular in shape, polygon of the opening of said pit or circle.Pit is a regular shape, makes it on blade, be convenient to arrange.
Preferably, said division wall is strip and interlaced so that said medial surface is netted.Netted blade makes the utility model not reduce on the blade monomer intensity based, and the ratio of the gross area of pit and division wall is reached maximum, further saves material.
Preferably, said pit is uniformly distributed in the medial surface of said blade, makes that the intensity of blade is even.
Preferably, the lateral surface of said blade is plane, is convenient to the shredded paper of hollow blade for shredding paper.
Correspondingly; The utility model also provides a kind of blade for shredding paper monomer; Said blade monomer comprises blade, is located at the installing hole at said blade center and the point of a knife that stretches out and form along said blade periphery; The one side of said blade is provided with some pits and forms the division wall of separating said pit, and said division wall interconnects, and said pit is covered with said blade and makes the one side of said blade be netted or cellular.
Preferably, triangular in shape, polygon of the opening of said pit or circle.Said division wall into strips and interlaced so that said medial surface is netted.Said pit is uniformly distributed in the medial surface of said blade.The lateral surface of said blade is plane.
Compared with prior art, the blade medial surface of the said blade for shredding paper of the utility model is netted or cellular, and the division wall that which is provided with some pits and separate said pit, above-mentioned technical characterictic make and the utlity model has following advantage:
On the one hand; Said some pits are covered with the material that said blade has been saved the blade monomer; And the division wall that interconnects has strengthened the intensity of blade monomer, even makes the intensity of the utility model blade for shredding paper be better than the solid blade for shredding paper of same thickness, not only can realize high-intensity shredded paper cutting; And not yielding, long service life.
On the other hand; Because each pit of the utility model is separated by said division wall; Make the cavity of fitting two blades the back forming be several areolas that has been spaced apart out; And the cavity of two blades is not necessarily relative, has further reduced the unit space of said cavity, and thin paper slip after guaranteeing to cut or particle can not be clipped in the cavity in the middle of the blade for shredding paper.
Again on the one hand, because said pit compartment of terrain has been covered with whole blade, when therefore making the blade monomer; Can on milling train, extrude a side earlier and have concavo-convex metallic plate; Again concavo-convex metallic plate is put into the diel punch forming and become blade, pit is processed through the mode of roll forming does not so not only have waste material, and when the moulding of blade monomer, need not the punching press pit; Reduced the tonnage demand of stamping machine, production technology is simple and cost is low.
