Abstract

The utility model relates to a knife flywheel of a paper breaker, which has the advantages of easy assembly and few failures. A knife flywheel blade of a paper breaker comprises knife flywheel blades. The utility model is characterized in that each knife flywheel blade is formed integrally and convexly extended with a long and a short convex seats from the periphery of a middle hole. The long convex seats of the adjacent knife flywheel blades are in mutual contact to form a long interval, and the short convex seats on the other side are in mutual contact to form a short interval. Thus, a plurality of knife flywheel blades of whole knife flywheel rods are repeatedly arranged in unequal intervals. As a consequence, when the two knife flywheel rods are arranged in parallel, the knife flywheel blades are mutually staggered to realize the shearing function. The utility model is used for cutting paper, etc.

Description

The paper crusher knife wheel sheet

The utility model relates to paper crusher knife wheel.

Existing paper crusher knife wheel is as shown in Figure 1, 2: two break bar bars 1 are arranged side by side, and the Knife flywheel blade 11 staggered forks of wearing are arranged, and form the shearing function of left and right sides balance therebetween; In the polygonal column 14 of central actuating shaft, with Knife flywheel blade 11, long spacer ring 12, Knife flywheel blade 11, short spacer ring 13 ... be arranged in break bar bar 1 in regular turn; Because long and

short spacer ring

12,13 length differences are apart from very little, between the thickness-1mm of about two Knife flywheel blades 11, it is accurate, accurate that assembling is difficult for, and influences the paper shear effect.And the spare part complexity, just in case one of them part generation problem will cause whole break bar bar loosening, influence is used.

The purpose of this utility model provides the paper crusher knife wheel sheet of a kind of easy assembling, few fault.

The purpose of this utility model is achieved in that the paper crusher knife wheel sheet, and it comprises Knife flywheel blade, it is characterized in that: that this each Knife flywheel blade is formed in one and extend from the periphery of mesopore and to be extruded with long and short prominent seat.

Above-mentioned design when many groups Knife flywheel blade is combined tandem when the driving rotating shaft forms the break bar bar, is with the prominent seat of the length of its adjacent Knife flywheel blade prominent of length is contradicted each other, and forms a long interval; The prominent seat of the weak point of another side contradicts each other to short prominent group, form a short interval, make whole break bar bar a plurality of Knife flywheel blades can with repeatedly not equi-spaced apart arrange, and then when two break bar bars are arranged side by side, make the interlaced one-tenth of Knife flywheel blade shear function, this shredded paper break bar with not equi-spaced apart effect has reached the effect that has easy assembling, lacks fault.

Below by accompanying drawing, embodiment the utility model is described further again.

The existing paper shredding blade wheels list of Fig. 1 props up break bar bar stereogram;

Fig. 2 has the state diagram arranged side by side of paper shredding blade wheels now;

Fig. 3,4 the utility model Knife flywheel blade stereograms;

Fig. 5 the utility model Knife flywheel blade and polygonal rotating shaft combination cross-sectional schematic;

Fig. 6 the utility model knife wheel set front view.

Shown in Fig. 3-6: the utility model comprises Knife flywheel blade 10, it is characterized in that: this each Knife flywheel blade 10 is that be formed in one and extend from the periphery of mesopore 100 and to be extruded with long and short prominent seat 102,105.Wherein, it is thin discoid that this Knife flywheel blade 10 is, its center is provided with and can holds the mesopore 100 that a polygonal rotating shaft 14 is passed through, along mesopore 100 peripheries, extend the prominent seat 102 of length of corresponding rotating shaft 14 corner portion 140 in the one side of Knife flywheel blade 10, the prominent seat of this length 102 ends are bent into one pinch of angle mouth 103 to the center, the corner portion 140 of this pinch angle mouth 103 in order to nip rotating shaft 14; At the another side of Knife flywheel blade 10, extend the prominent seat 105 of weak point of the planar portions 141 of corresponding rotating shaft 14 along mesopore 100 peripheries, the center of the prominent seat of this weak point 105 ends is bent into one pinch of plate 106 and nips the planar portions 141 of polygonal rotating shaft 14.

This shows, the utility model makes a plurality of Knife flywheel blade 10 tandems in rotating shaft 14, arrange with the Knife flywheel blade that forms break bar bar 1 and to have the unequal-interval of arranging repeatedly, and long and short prominent seat 102,104 all has to pinch and smashs heart rotating shaft 14 and make Knife flywheel blade 10 directly be driven and be formed break bar by polygonal rotating shaft 14.

Claims

1, paper crusher knife wheel sheet, it comprises Knife flywheel blade, it is characterized in that: that this each Knife flywheel blade is formed in one and extend from the periphery of mesopore and to be extruded with long and short prominent seat.

2, paper crusher knife wheel sheet as claimed in claim 1, it is characterized in that: wherein, it is thin discoid that this Knife flywheel blade is, its center is provided with and can holds the mesopore that a polygonal rotating shaft is passed through, along the mesopore periphery, extend the prominent seat of length of corresponding shaft rotary corner portion in the one side of Knife flywheel blade, the prominent seat end of this length is bent into one pinch of angle mouth to the center, and this pinch angle mouth is in order to nip the corner portion of rotating shaft; At the another side of Knife flywheel blade, extend the prominent seat of weak point of the planar portions of corresponding rotating shaft along central peripheral, the terminal center of the prominent seat of this weak point is bent into one pinch of plate and nips the planar portions of polygonal rotating shaft.
