Abstract
The invention discloses a shredder cutter, which comprises a cutter shaft and blades, wherein the outer circumference of the cutter shaft is in a regularly dodecagonal shape, and the inner hole of each blade is matched with the outer circumference of the cutter shaft; seventeen cuter teeth are uniformly distributed on the outer circumference of each blade, and a group of blades are arranged on the cutter shaft; every adjacent blades relatively rotate 1.76 degrees, and a distance sleeve is arranged between the adjacent blades; the tip of each cutter tooth is in a curved shape, and the thickness of each blade is between 1.9mm and 2.1mm; and the distance between the adjacent blades is between 1.9mm and 2.1mm. According to the shedder cutter, a group of blades are arranged on the cutter shaft, and every two adjacent blades relatively rotate 1.76 degrees to form a one-way spiral groove; the one-way spiral groove cutter is more stable than a V-shaped spiral line cutter, so that paper is not accumulated in the middle; with the spiral line matched by the method, the paper cutting force of the cutter shaft can be smaller in the whole length, the service life of the blades can be prolonged, and meanwhile, 1-2 more sheets of paper can be cut every time compared with the traditional cuttuer, so that the shredding efficiency is improved.
Description
Technical field
The present invention relates to a kind of cutter, particularly a kind of cutter for paper grinder belongs to office equipment component technology field.
Background technology
In the office appliance, shredder has been a common equipment, includes cutter for paper grinder in the shredder in the core component at present; Said cutter for paper grinder comprises cutter shaft, blade usually; Being installed on the cutter shaft of the arrangement of said blade rule; Arrangement mode commonly used at present is " V " shape; This cutter for paper grinder is easy paperboard in use, causes the paper jam of shredder.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed that a kind of shredded paper efficient is high, the life-span is long, the improved cutter for paper grinder of paper jam not.
Technical solution of the present invention is achieved in that a kind of cutter for paper grinder, comprises cutter shaft, blade; The excircle of said cutter shaft is positive 12 limit shapes; Said blade endoporus is for to match with the excircle of cutter shaft; Be provided with 17 cutters tooth on the excircle of said blade equably; Be provided with one group of blade on the said cutter shaft, every adjacent knife blades is rotated a degree relatively; Be provided with separation sleeve between adjacent knife blades; Said a is 1.76.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Because cutter for paper grinder of the present invention is provided with one group of blade on the said cutter shaft, every adjacent knife blades rotation 1.76 degree relatively forms the one-way spiral groove; The one-way spiral groove is more stable than V-type helix cutting knife, long-pending paper in the middle of not allowing to occur; The helix of being joined by this way can make the paper cutting force of cutter shaft on total length littler, can prolong the service life of blade, at every turn can cut 1-2 simultaneously more and open paper, has improved shredded paper efficient.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1 is the stereogram of cutter for paper grinder of the present invention;
Fig. 2 is the front view of cutter for paper grinder of the present invention;
Fig. 3 is the left view of cutter for paper grinder of the present invention;
Fig. 4 is the stereogram of cutter shaft of the present invention;
Fig. 5 is the left view of cutter shaft of the present invention;
Fig. 6 is the stereogram of blade of the present invention;
Wherein: 1, cutter shaft; 2, blade; 3, cutter tooth; 4, separation sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of cutter for paper grinder of the present invention like Fig. 1-6, comprise cutter shaft 1, blade 2; The excircle of said cutter shaft 1 is positive 12 limit shapes; Said blade 2 endoporus are for to match with the excircle of cutter shaft 1; Be provided with 17 cutters tooth 3 on the excircle of said blade 2 equably; Be provided with one group of blade 3 on the said cutter shaft 1, the angle that every adjacent knife blades is rotated between the relative cutter tooth that a degree also is an adjacent knife blades (3a, 3b) relatively is a degree; Be provided with separation sleeve 4 between adjacent knife blades; Said a is 1.76; The tip of said cutter tooth 3 is a curve; The thickness of said blade 2 is 2mm; Spacing distance between the said adjacent knife blades 2 is 2mm.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Because cutter for paper grinder of the present invention is provided with one group of blade on the said cutter shaft, every adjacent knife blades rotation 1.76 degree relatively forms the one-way spiral groove; The one-way spiral groove is more stable than V-type helix cutting knife, long-pending paper in the middle of not allowing to occur; The helix of being joined by this way can make the paper cutting force of cutter shaft on total length littler, can prolong the service life of blade, at every turn can cut 1-2 simultaneously more and open paper, has improved shredded paper efficient.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
