Particularly, with reference to figure 4, Fig. 6, Fig. 7 and Fig. 9, described rimmer knife tooth 121 and described short sword tooth 122 have first shear surface 1211 and second shear surface 1221 respectively.Described first shear surface 1211 intersects with the surface of described cutter shaft 12 and forms first intersection, and the plane of crossing described first intersection and being tangential on described cutter shaft 12 surfaces is spent greater than 90 with the angle α that described first shear surface 1211 forms.Preferably, described angle α is 120 degree.Described second shear surface 1221 intersects with the surface of described cutter shaft 12 and forms second intersection, and the plane of crossing described second intersection and being tangential on described cutter shaft 12 surfaces is spent greater than 90 with the angle β that described second shear surface 1221 forms.Preferably, described angle β is 120 degree.And the central axis 120 of described cutter shaft 12 is positioned at the upper right side of described flange 112.Like this, cutting is during paper, and first shear surface 1211 of described rimmer knife tooth 121 and second shear surface 1221 of described short sword tooth 122 can not only the THE ADIABATIC SHEAR IN paper, and can automatically the paper that shreds be withdrawed from.
Preferably, described rimmer knife tooth 121 and described short sword tooth 122 are respectively along two radial diameter symmetries of described cutter shaft 12.Described rimmer knife tooth 121 has the symmetry axis symmetry of 1211, two described first shear surfaces 1211 of two described first shear surfaces along described rimmer knife tooth 121.Described short sword tooth 122 also has the symmetry axis symmetry of 1221, two described second shear surfaces 1221 of two second shear surfaces along described short sword tooth 122.Like this, make that described cutter shaft 12 mounting means are flexible.
As Fig. 8 and shown in Figure 9, described shredder 20 comprises described paper shredding cutters 10 and paper feed mechanism 30.Described paper feed mechanism 30 comprises two intake rollers 31 and 32, and described intake roller 31 and 32 is installed in rotation on two described installing racks 111, and two described intake rollers 31 and 32 side relative with described cutter shaft 12 of being positioned at described cutter table 11.Treat that broken paper 33 enters from the centre of two described intake rollers 31 and 32, and be delivered to flange 112 places of the cutter table 11 of described paper shredding cutters 10 by two described intake rollers 31 and 32, thereby by cooperating of described rimmer knife tooth 121 and described breach 1121 and cooperating of described short sword tooth 122 and described double wedge 1122, carry out the process of shredded paper respectively.
Do a detailed explanation below in conjunction with the operation principle of Fig. 8-9 pair of shredder 20 of the present invention: two intake rollers 31 and 32 rotate under the driving of paper feed drive unit (not shown), thereby will be clipped in paper 33 in the middle of two intake rollers 31 and 32 are transported to cutter table 11 along the upper surface of the cutter table 11 of paper shredding cutters 10 flange 112 places.Simultaneously, cutter shaft 12 rotates under the driving of gear (not shown), thereby the rimmer knife tooth 121 and the short sword tooth 122 that drive on the cutter shaft 12 rotate, when described rimmer knife tooth 121 enters in the breach 1121 of cutter table 11, when perhaps short sword tooth 122 turns to double wedge 1122 places, rimmer knife tooth 121 cooperates with breach 1121, or short sword tooth 1122 and double wedge 1122 cooperations, and paper 33 is carried out the part cutting.Then, when short sword tooth 122 turns to double wedge 1122 places, perhaps rimmer knife tooth 121 enters in the breach 1121 of cutter table 11, short sword tooth 122 cooperates with double wedge 1122, perhaps rimmer knife tooth 121 cooperates with breach 1121, the part of not shearing to paper 33 is sheared, thereby finishes the shearing to paper 33.Understandably, if the user need cut into the tiny scraps of paper or particle with paper 33, the paper feeding speed that can control paper feed mechanism 30 is slack-off, thereby paper 33 is cut into the tiny scraps of paper or particle.
Therefore, because paper shredding cutters 10 of the present invention is made up of the cutter shaft 12 and the fixed cutter table 11 of rotating, cut paper speed is the velocity of rotation decision by cutter shaft 12, paper 33 to be cut is to be delivered to paper shredding cutters 10 by the paper feed mechanism of controlling separately in addition 30, like this, cut paper and paper feed can be controlled respectively, thereby can be in the process of cutting according to user's needs, control the size of the scraps of paper of chopping by the paper feeding speed of control paper 33, so the shredded paper privacy degrees of paper shredding cutters 10 of the present invention is unrestricted, can carry out multi-stage paper shredding.On the other hand, because paper shredding cutters 10 of the present invention is to utilize rimmer knife tooth 121 and 122 pairs of paper 33 of short sword tooth to shear, after the shearing, rimmer knife tooth 121 and short sword tooth 122 can be drained the paper of chopping automatically, thereby paper shredding cutters 10 of the present invention do not need independent from mechanism of paper, thereby reduced production cost and installation difficulty.
