Description

Shredder is with novel thin blade and set of blades thereof

Technical field

The utility model relates to a kind of novel shredder cutting blade, more specifically, relate to a kind of with foil by the mechanical stamping moulding, or the novel thin set of blades of the novel thin blade of die cast and corresponding formation.

Background technology

Shredder at present commonly used has two kinds of vertical bar formula shredder (stripe-cut shredders) and crushing type shredders (cross-cutshredders).Its basic functional principle is to be set on the cutter shaft with cutting blade collocation spacer ring, and it is right to utilize motor and geared system to drive two parallel and counterrotating cutter shafts, and the paper that the shearing force that utilization forms will be passed through cuts into fine strip shape.

See also the common blades schematic diagram of Fig. 1 shredder commonly used and the common blades combination stereogram of Fig. 2 shredder commonly used, this common blades is material with the metal sheet, be shaped to circular shear blade by mould with mechanical stamping, blade center forms a polygonal centre bore 1 that can supply cutter shaft to run through, the blade circumference is outwards given prominence to every about 90 degree and is formed with hook-shaped blade 2, when two blades that are applied in cutter shaft F as shown in Figure 2 are merged into a set of blades H in back-to-back (back-to-back) mode, the hook-shaped blade of these two blades will form the approximate V font edge of a knife 3, then two blades be separated with the spacer ring (not shown) on the cutter shaft F ' of opposite and form another set of blades H ' in the mode of (face-to-face) face-to-face.When the paper of needs fragmentation by two counterrotating cutter shaft F, F ' time, via the blade circumference be so-called cutter 4 and cutter 4 ' relatively rotate, paper is as cutting as scissors, again via the edge of a knife 3 and opposite cutter 4 ' the relative motion paper slip horizontal cutting that will cut already become broken official form for filing a lawsuit sheet.

The common blades of shredder commonly used is formed through the mould integrated punching by the metal sheet of 1.5mm, 2.0mm, 2.5mm or 3.0mm equal thickness usually now, accordingly, it is thick that independent one group of blade unit is respectively 3.0mm, 4.0mm, 5.0mm or 6.0mm, wide 3.0mm, 4.0mm, 5.0mm or the 6.0mm of being respectively mutually of thus obtained shredded paper, its length can be 6mm, 10mm, 23mm, 37mm, 44mm or 55mm etc. according to external diameter and the point of a knife number of itself.

Because in the shredded paper process, relative two groups of blades are to have point of a knife to prick the hole earlier on paper, cut (squeeze and open) again, after pull apart the paper scrap (as shown in Figure 2) of the shape that becomes to break, because the width that cuts the back paper slip is equal to the thickness of common blades group, and be to guarantee the intensity of blade when carrying out horizontal cutting, higher to the point of a knife requirement of strength, blade thickness can not be too thin otherwise blade will have distortion even broken possibility, so adopt corresponding thicker material to be stamped to form, this restriction causes material cost high, can't adapt to the violent day by day industry present situation of shredder price competition really.In addition, because the thickness of common blades can fall,, need more high-powerly could drive two groups of combination cutter shafts and carry out the shredded paper function again because blade is an entity, and its quality is heavier relatively.

For the problems referred to above and the defective that solves existence, be necessary very much the common blades of shredder commonly used is improved.

The specific embodiment

In order more to be expressly understood technology contents of the present utility model, see also Fig. 3 to shown in Figure 7.

For the deficiency of the blade that overcomes shredder commonly used, pass through long term studies and test now, successfully create and can replace present shredder cutting blade, can reach the novel thin blade of same shredded paper requirement.As shown in Figure 3, novel thin blade 10 of the present utility model mainly is made of cutter portion 11, cutter 12, wherein:

Novel thin blade 10 is to adopt sheet metal that thickness is about 0.3mm～1.0mm through the mechanical stamping moulding, or the disk shape blade of die cast.The circumferential outer outstanding cutter portion 11 that forms of disk shape blade, or form cutter portion 11, or outstanding formation cutter portion 11 every arbitrarily angled outside as required every about 180 degree or every 90 degree are outwards outstanding.See also Fig. 3, Fig. 4, Fig. 5 and Fig. 6 b, cutter portion 11 is the blade 111 of the common blade profile of tool, be used to puncture the paper of pulling apart the needs fragmentation, the blade difference of the more general direct punching press of processing of blade 111 inside, it makes the blade center protrusion go out subtriangular muscle platform 151 by mechanical stamping, the edge of the muscle platform 151 of projection has thickened the edge of blade 111, the height of muscle platform 151 can be any, but be generally 1.5mm, 2.0mm, 2.5mm or 3.0mm, promptly make the thin blade of original 0.3mm～1.0mm reach 1.5mm by muscle platform 151,2.0mm, 2.5mm or the whole profile thickness of 3.0mm, as Fig. 3, Fig. 4, shown in Fig. 6 a and Fig. 6 c, thereby satisfy the demand that paper size after the fragmentation is had requirement, and strengthened the intensity of whole point of a knife, and make blade 111 can finish the action of shredded paper and can not be damaged, two blades can be pulled apart (seeing also Fig. 7) to the paper that has punctured after overlapping relatively and forming one group of set of blades completely.

There is the hole 13 that can intert knife pivot of paper crusher at the center of novel thin blade 10, and hole 13 is generally polygonal holes, runs through connection for cutter shaft.On the cutter of novel thin blade 10 12, with muscle platform 151 in the same way, central protrusion forms a big muscle platform 152, highly be no more than muscle platform 151, communicate or do not communicate with muscle platform 151, big muscle platform 152 shapes are any, but generally have symmetry, so that the balance of blade is good.Muscle platform 151 and big muscle platform 152 play the effect of the bending strength that strengthens novel thin blade 10 simultaneously.Novel thin blade 10 also can be other suitable shapes such as equilateral triangle, square or other regular polygons.

When two that are applied in cutter shaft A as shown in Figure 7 novel thin blade A1 and B1 in back-to-back (back-to-back) mode, be the mode of muscle position by the muscle position, when being merged into a set of blades 16, the cutter portion of these two blades combines the approximate V font edge of a knife 17 of formation, set of blades 16 is one group of cutter unit, be separated by with spacer ring 19 between many group cutter units, make that the interval between two groups of cutter units just is the thickness of one group of cutter unit, be through cutter shaft A and go up formation cutter shaft A group, then two blades are separated with spacer ring 19 on the cutter shaft B of opposite and form another set of blades 18 in the face-to-face mode of (face-to-face), set of blades 18 is another group cutter unit, and a plurality of cutter units tightly are through cutter shaft B in tool setting portion of cutter portion mode and go up formation cutter shaft B group.

Like this, when two groups of cutter shaft group A carry out relative the rotation with B by the drive of motor, set of blades 16 and set of blades 18 relative rotations, when the paper of needs fragmentation by two counterrotating cutter shaft A, during B, via the blade circumference be so-called cutter 12 and cutter 12 ' relatively rotate, paper is as cutting as scissors, again via the V font edge of a knife 17 and opposite cutter 12 ' relative motion, the V font edge of a knife 17 at first punctures needs broken paper, again the paper that punctures is pulled apart, thereby the paper slip horizontal cutting that will cut already becomes broken official form for filing a lawsuit sheet, thus the function of realization shredded paper.

In fact, set of blades 16 just is equivalent to the function that blade unit realized of (as shown in Figure 2) originally with the function that set of blades 18 realizes, but unique design with upper member by novel thin blade 10, such as the big muscle platform 152 of cutter 12 (as Fig. 3, shown in Fig. 6 a and Fig. 6 c), the muscle platform 151 of blade 11 is (as Fig. 3, Fig. 5, shown in Fig. 6 a and Fig. 6 b), when having reached the same shredded paper effect of shredder commonly used, greatly reduce the weight of blade, reached the purpose that reduces single-piece production material cost and complete machine cost greatly, thereby greatly reduce production cost, simultaneously because the reduction of blade weight, also greatly reduce the power consumption of motor, thereby saved the energy.The height of the muscle platform 151 on the cutter of novel thin blade 10 12 more hour can be pulverized paper more brokenly than shredder commonly used.

Need to prove that in this specification, the utility model is described with reference to its certain embodiments.But obviously, those skilled in the art still can make various changes or modifications the utility model and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
