[specific embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, kneader knife chip module 100 with the utility model kneader bar 10 comprises two turning cylinders that be arranged in parallel 11,12, fixed cover is provided with some kneader bars 10 on each turning cylinder 11,12, kneader bar 10 on one of them turning cylinder 11 staggers mutually with the kneader bar 10 on another turning cylinder 12, but the edge fits together mutually, thereby when treating that shredded paper enters on this two turning cylinder 11,12 between the kneader bar 10, this kneader bar 10 can treat that shredded paper shreds to this.
In the present embodiment, kneader bar 10 shapes on above-mentioned two turning cylinders 11,12, structure are identical.Therefore, below only a kneader bar 10 be elaborated for example.
As shown in figures 1 and 3, this kneader bar 10 comprises with the paired dish type first blade monomer 14 and the second blade monomer 15 that axis is installed.The center of the first blade monomer 14 and the second blade monomer 15 offers first installing hole 141 and second installing hole 151 respectively, and the inner surface of this first installing hole 141 and second installing hole 151 evenly is provided with some triangle projections 142,152, to playing 142,152 by tubercula, corresponding turning cylinder 11,12 outer surfaces also are provided with accommodates groove accordingly, install thereby be convenient to this first blade monomer 14 and the second blade monomer, 15 coaxial lines, and can rotate with this correspondence turning cylinder 11,12.
As shown in figures 1 and 3, the edge of this first blade monomer 14 and the second blade monomer 15 extends outward two pairs of disconnected paper blades, i.e. the first disconnected paper blade 143 and the second disconnected paper blade 153.The disconnected paper blade of this two couple is interval 180 degree circumferentially, and also space set is many to disconnected paper blade, as three pairs, four equities as required certainly.
As shown in Figures 2 and 3, because the shape of every pair of disconnected paper blade, structure are identical, below only a pair ofly be elaborated for example.The first disconnected paper blade 143 and the second disconnected paper blade 153 are to draw close the arc-shaped bend setting in opposite directions mutually, thereby make two extending ends of this first disconnected paper blade 143 and the second disconnected paper blade 153 fit together, and cut off and treat shredded paper.
Extremely shown in Figure 19 as Fig. 1, Fig. 2, Fig. 3, Fig. 8 to Figure 11 and Figure 16, treat shredded paper in order to cut off better, the top 1433,1533 of this first disconnected paper blade 143 and the second disconnected paper blade 153 respectively is provided with first, second contact-making surface 1431,1531 of vertical mutual applying, thereby make the extending end of this first disconnected paper blade 143 and the second disconnected paper blade 153 more stably fit together, guarantee the cutting direction of the first disconnected paper blade 143 and the second disconnected paper blade 153; And the cross section of the disconnected paper of first, second of a side of being located at this first disconnected paper blade 143 and the second disconnected paper blade 153 portion 1432,1532 becomes pointed shape, forms blade, and this pointed shape blade can cut off tartly and treat shredded paper, improves and cuts off the effect for the treatment of shredded paper.In addition, the top 1433,1533 of this first disconnected paper blade 143 and the second disconnected paper blade 153 be pointed shape, treat shredded paper thereby also be beneficial to cut off.
As Fig. 1, Fig. 3, Fig. 4, Fig. 6, Fig. 8, Figure 12, Figure 13 and shown in Figure 16, this dish type first blade monomer 14 is along first projection, 144 and second projection 145 of its stretched annular in installation shaft alignment front and back, first installing hole 141 is located on the top of this first projection 144, thereby the end face of this first projection, 144 and second projection 145 forms and first convex surface 1441 and second convex surface 1451 that are the sealing annular that axis normal is installed.This dish type second blade monomer 15 is along the 3rd projection the 154 and the 4th projection 155 of its stretched annular in installation shaft alignment front and back, second installing hole 151 is located on the top of the 3rd projection 154, thereby the end face of the 3rd projection the 154 and the 4th projection 155 forms and the 3rd convex surface 1541 and the 4th convex surface 1551 that are the sealing annular that axis normal is installed.Wherein this first convex surface 1441 and second convex surface 1451 respectively with the 3rd convex surface 1541 and the 1551 corresponding settings of the 4th convex surface.
As Fig. 1, Fig. 3, Fig. 6, Fig. 8, shown in Figure 13 and Fig. 16, when some kneader bars 10 are installed in same turning cylinder 11, after on 12, first convex surface 1441 of same kneader bar 10 and the 1541 corresponding applyings of the 3rd convex surface, this second convex surface 1451 and the 4th convex surface 1551 respectively with the 4th convex surface 1551 and the 1451 corresponding applyings of second convex surface of adjacent kneader bar 10, in order to replace the cutter ring in traditional shredder assembling, thereby cause the width of the thickness sum of the first blade monomer 14 and the second blade monomer 15, so this kneader bar 10 can be saved material less than the shredded paper that cuts out; And prevent that shredded paper from entering generation coil paper phenomenon in the kneader bar 10; Can avoid also simultaneously that to produce assembling bad because of cutter ring size precision in the prior art produces cumulative errors, thereby improve its assembly precision.
In addition, extremely shown in Figure 15 as Fig. 4 to Fig. 7 and Figure 12, the peripheral intervals of this first blade monomer 14 is provided with some first cutters tooth 146; The peripheral intervals of this second blade monomer 15 is provided with some second cutters tooth 156.As optimal way, these some first cutters tooth 146 and some second cutter tooth, 156 indentations.And each first cutter tooth 146 back to the surface 1461 of the second blade monomer 15 for being obliquely installed, form first basil; This second cutter tooth 156 for being obliquely installed, forms second basil back to the surface 1561 of the first blade monomer 14.This first basil and second basil can produce the forward and backward angle of cutting, are beneficial to cutting, promote tatter amount.
Although the utility model is disclosed by above embodiment, but scope of the present utility model is not limited thereto, do not departing under the condition of the utility model design, more than each element or construct available under technical field personnel similar or equivalent element or the structure understood replace.
