Abstract

The utility model relates to a cataclasm type blade of kneader, including the center be equipped with with shredder cutter shaft complex centre bore, peripheral evagination has the cutting edge, its characterized in that, periphery still are equipped with a little cutting edge at least, little cutting edge lies in between two cutting edges, the height that highly is lighter than the cutting edge of little cutting edge. Blade through the little cutting edge that increases can effectively cut the paper, the paper of knife sword between with two cutting edges supports and is taut, makes things convenient for the cutting edge to prick disconnected paper, and the cutting edge that improves the blade is to the disconnected effect of the bundle of paper.

Description

A kind of fracture type blade of shredder

Technical field

This utility model belongs to shredder technical field, is specifically related to the fracture type blade of a kind of shredder.

Background technology

People often have file paper in daily life or work to be needed to destroy, thus preventing other people from obtaining data described on file, shredder has become people to destroy the important tool of file.

No matter existing shredder is electronic or manual, substantially can be divided into two kinds, and one utilizes its blade that waste paper is cut to acinous, and one is fine strip shape.It is broken into granuliform shredder to be usually and be broken in the process of strip by the scraps of paper, the paper of strip is carried out cataclasm simultaneously, the particulate after cataclasm, it is usually the distance between two blades on blade.Owing to the blade of insert periphery is in the process of cataclasm paper scrap, being in hanging shape by the lower end of cataclasm paper scrap, blade carries out under without corresponding support paper scrap is cataclasm, therefore that the cataclasm effect of paper scrap is less desirable.

Existing shredder fracture type blade, is provided with the centre bore coordinated with knife pivot of paper crusher including center, and periphery evagination has blade, and the quantity of blade and size are different and design, generally at least 2 according to shredded paper size and number, as shown in Figure 1 and Figure 2.Existing blade Shortcomings part, as knife-edge cutting edge cut paper is not opened, point of a knife pricks the continuous phenomenon of paper. and having research design to pass through to strengthen point of a knife, increase knife-edge cutting edge external diameter, this can increase cost.As Chinese patent description CN201783367U discloses a kind of high cataclasm rate kneader bar, but the support effect of lug is unsatisfactory.

Utility model content

For solving the not enough problem that present technology exists, the utility model proposes the fracture type blade of a kind of shredder, improve the blade disconnected effect of bundle to paper of blade.

The technical solution adopted in the utility model is as follows.

The fracture type blade of shredder includes center and is provided with the centre bore coordinated with knife pivot of paper crusher, and periphery evagination has blade, it is characterised in that periphery is also at least provided with a small knife edge, and small knife edge is between two blades, and the height of small knife edge is less than the height of blade.

In above technical scheme, having at least a small knife edge is in the centre of two blades, and all the other small knife edges are symmetrically distributed in middle small knife edge both sides.

In above technical scheme, the quantity of the small knife edge between adjacent two blades is 1 or 3, has at least a small knife edge to be located at the centre of two blades.

In above technical scheme, all the other small knife edges are symmetrically distributed in the both sides of middle small knife edge, form 30 degree or 20 degree of angles with middle small knife edge.

In above technical scheme, the shape of described small knife edge is pointed or one or more in rectangle, semicircular arc or circular arc.

Knife height or the constant situation of outside dimension, namely basic when not changing cost, blade is by increasing small knife edge, reach following purpose, the cutter shaft of shredder is usually regular hexagon, the centre bore of kneader bar, it is common that N number of regular hexagon, N is usually 1,2 or 3, when such blade penetrates cutter shaft, it is possible to rotate to an angle, blade is made to become helical arrangement on cutter shaft, which reduce the blade quantity at the disconnected paper of bundle of same time, and reach labour-saving effect.

The technical solution of the utility model have technical effect that, can effectively cut paper by the cutting edge of small knife edge increased；Small knife edge, by the sheet support between two blades and tension, facilitates blade to prick disconnected paper, improves the blade disconnected effect of bundle to paper of blade.

Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is elaborated.

As shown in Figure 3, the fracture type blade of the present embodiment includes center and is provided with the centre bore 1 coordinated with knife pivot of paper crusher, periphery evagination has two blades 2, has small knife edge 3 between two blades, and the height of small knife edge or outside dimension are less than the height of blade or outside dimension, the quantity of small knife edge is six, dividing two groups of each three both sides being distributed in blade, often group has a small knife edge 3a to be in the centre of two blades 2a, 2b, another two small knife edge 3b, 3c are in middle small knife edge lateral symmetry distribution.

Such as Fig. 3, Fig. 4, shown in Fig. 5 and Fig. 6, when two groups of knife pivot of paper crusher rotate, paper 4 is cut by the knife-edge cutting edge 5 of two relative blades, paper 4 is pricked disconnected by the point of a knife 21 of blade, the size of small knife edge is bigger than the outer rim at knife-edge cutting edge place, more effective incision paper 4, paper 4 between two blades is supported and strains by small knife edge, blade is facilitated to prick disconnected paper 4, wherein small knife edge 3a is distributed in blade 2a, knife-edge cutting edge institute between 2b is circumferentially, small knife edge 3b, it is 30 degree that 3c is then symmetrically distributed in the small knife edge 3a both sides difference number of degrees, here it is dodecagon that 30 degree are because blade endoporus, blade rotation angle is 360/12=30 degree.

As it is shown in figure 9, small knife edge shape is pointed or one in rectangle, semicircular arc or circular arc, the height of small knife edge blade point and and blade cutting edge between.The tip of small knife edge 33 is rounding on small knife edge 32 basis, and small knife edge 34 is two of small knife edge 33, and tip rounding desirably prevents the disconnected paper in too Jianzha County, tip.

As shown in Figure 7, Figure 8, fracture type blade for another embodiment, the centre bore coordinated with knife pivot of paper crusher it is provided with including center, periphery evagination has four blades, small knife edge is had between every two blades, the height of small knife edge or outside dimension are less than the height of blade or outside dimension, and small knife edge is provided in the centre of two blades.
