Abstract
The utility model provides a kneader cut paper blade, blade group and cutters that is efficient and the shredded paper is effectual. Including blade tip part, knife face portion and back of a knife blade portion, the last pressure arm of angle of blade tip part is located different avriss respectively with sunk angle limit in the back of a knife blade portion, presses the outer fringe of the arm of angle and knife tip to meet, and its inner edge and knife face portion meet, the outer fringe and the blade circumference outer wall on sunk angle limit meet, and its inner edge meets with back of a knife blade portion. The utility model discloses breaking through to some extent on blade stamping process and assembly method, setting up the pressure arm of angle on the blade blade tip part and sunk angle limit in the back of a knife blade portion at different avriss respectively, press arm of angle setting in knife face portion, the sunk angle limit sets up in back of a knife blade portion, again with two such razor blade assembly one -tenth blade groups, then recomposition cutters. It thoroughly eliminates the point portion clearance among the prior art. Making the shredded paper roll the paper effect and obviously improving, the paper of incision does not have long note form, can not appear pressing from both sides paper stopper paper phenomenon between two blades yet, has improved the paper percentage of damage greatly.
Description
Technical field
The utility model is related to a kind of shredder, more particularly to a kind of with a kind of cut paper of novel blade for shredder master
Blade, set of blades and cutter.
Background technology
Paper cutting blade of paper shredder of the prior art is generally made up of (such as Fig. 1,2 institutes left-hand blade 1 and dextrad blade 2
Show), then by left-hand blade 1 and dextrad blade 2 with knife back portion 5 (one side with sharp edges on blade is referred to as into knife face portion 4,
The one side that bevel edge is processed in corner on blade is referred to as into knife back portion 5, claims outer circumferential walls 6 by blade periphery, similarly hereinafter) connect
Mode constitute paper cutting blade group 7 (as shown in Figure 3), afterwards some groups of paper cutting blade groups 7 are be arranged in parallel installed in two again
Rotating shaft 9 on constitute cutter 8 (as shown in Figure 4), paper cutting blade group 7 in two rotating shafts 9 is overlapped alternately and locally.
When using, the paper that will be crushed is sent into by the overlapping part of paper cutting blade group 7, you can cut in nose part 3 and tearing for knife face portion 4
Cut off and be broken for paper scrap.
Above-mentioned left-hand blade 1 and dextrad blade 2, the pressure arm of angle 31 of nose part 3 thereon is (i.e. in the side of nose part 3
Bevel edge is processed into, similarly hereinafter) it is respectively positioned on the knife back portion 5 of the blade with the arm of angle 51 that collapses (also referred to as bevel edge, similarly hereinafter) in knife back portion 5
Side, so, when left-hand blade 1 and dextrad blade 2 are connected into the composition set of blades 7 in the way of knife back portion 5 connects, two knives
A gap (hereinafter referred to as tip clearance 71) triangular in shape, the point are just formed between the pressure arm of angle 31 of the nose part 3 on piece
Portion gap 71 can produce following defect：
1) it is well known that on blade the effect of nose part 3 be for pulling paper and paper being pricked into disconnected, i.e., in paper X side
Upwards the paper is pricked into disconnected, and the effect of knife face portion 4 is for by paper cutting growth paper slip shape, i.e., by the paper in paper Y-direction
Open and isolate, thus, paper is crushed.But described tip clearance 71 cause shredded paper to roll paper effect is undesirable always, the paper of incision
Zhang Chengchang paper slip shapes are more.
2) the easy holding paper plug paper of tip clearance 71, the shredded paper filled in during shredded paper in the tip clearance 71 is continuous
Extruding and produce outside component f, make left-hand blade 1 and the dextrad blade 2 there is detached tendency, time length can make nose part 3
Flexural deformation.

Reference is as follows：
Left-hand blade 1, dextrad blade 2, nose part 3, pressure the arm of angle 31, knife face portion 4, knife back portion 5, the arm of angle 51 that collapses,
Outer circumferential walls 6, set of blades 7, tip clearance 71, cutter 8, rotating shaft 9, component f, pressure F.
Specific embodiment
As shown in Figure 7,8, paper cutting blade of paper shredder of the present utility model point left-hand blade 1 and dextrad blade 2, every blade
The upper outer circumferential walls 6 for including nose part 3, knife face portion 4, knife back portion 5 and blade, on every blade its even circumferential of ring be provided with to
Few three shape identical nose parts 3, described blade thickness can be in 0.4mm-3.0mm.
The nose part 3 refers to the part of point of a knife, and it is cutting edge of a knife or a sword that knife face portion 4 is referred on blade with the angle between outer circumferential walls 6
That surface of Li Jiao, knife back portion 5 refers to that face for being down a hypotenuse on blade with the angle between outer circumferential walls 6.
The left-hand blade 1 and dextrad blade 2 referred to when knife face portion 4 thereon is placed in the same plane, nose part 3 thereon
Point of a knife points to contrary or opposite.
The utility model is that the pressure arm of angle 31 in the nose part 3 by every blade is distinguished with the arm of angle 51 that collapses in knife back portion 5
Different avris are arranged on, the pressure arm of angle 31 is arranged at into the side of knife face portion 4, the arm of angle 51 that will collapse is arranged at the side of knife back portion 5, will
The outer rim of the pressure arm of angle 31 connects (be away from the blade center of circle outer, the proximity blade center of circle is interior), its inner rim and knife face with point of a knife
Portion 4 connects；The outer rim of the arm of angle 51 that collapses connects with blade outer circumferential walls 6, and its inner rim connects with knife back portion 5.
As shown in figure 9, paper cutting blade of paper shredder group 7 of the present utility model is by described left-hand blade 1 and dextrad blade 2
Set of blades 7 is combined in the coaxial mode of connecting side by side in knife back portion 5, so, the set of blades 7 for being constituted without tip clearance 71, and
Knife face portion 4 is exposed outside.Wherein, the nose part 3 on left-hand blade 1 is identical stacked with the nose part 3 on dextrad blade 2.
If left-hand blade 1 of the prior art and dextrad blade 2 are combined into into the set of blades 7 without tip clearance 71,
Structure as shown in Figure 5,6 occurs, i.e. the knife face portion 4 of two blades connects, and knife back face then it is exposed outside, actual broken
Paper can only be punctured but can not slitted the paper into vertical bar for it during paper, therefore not reach the mesh that paper is broken into disconnected official form for filing a lawsuit bits
, i.e., cannot carry out shredded paper.
As shown in Figure 10, shredder cutter 8 of the present utility model is some groups of aforesaid set of blades 7 to be assembled two
In individual parallel and tool rotating shaft 9 at regular intervals, the blade being characterized in the rotating shaft of set of blades 7 and second in first rotating shaft
Group 7 is alternately locally overlapped successively on the centerline direction of first rotating shaft and the second rotating shaft spacing, described in per two adjacent groups
Paper cutting blade of paper shredder group 7 with 0-0.25mm gaps setting, in the plane that connects, the nose part 3 in two groups of set of blades 7 is wrong
Position is arranged.
Without described tip clearance 71, nose part 3 is easy to prick disconnected by paper and cuts the cutter 8 of said structure,
And during shredded paper, the shredded paper in every group of both sides space of set of blades 7 can produce the pressure to this group of set of blades knife back portion 5
F, thus, the point of a knife that more closely makes for making that left-hand blade 1 and dextrad blade 2 combine is difficult flexural deformation, and shredded paper is more laborsaving so reach
To the effect of shredded paper energy-conservation.
