Abstract
A high-breakage-rate paper shredder blade comprises a circular blade body. Knife points protruded outwards are arranged at the peripheral edge of the circuit blade body, and an axis hole matching with a shaft lever is arranged at the center of the circular blade body. The high-breakage-rate paper shredder blade is characterized in that the periphery of the circular blade body is provided with at least one convex lug lower than the knife points. Compared with the prior art, the high-breakage-rate paper shredder blade has the advantages that on the condition of not changing standard dimension of the largest outer diameter positions (the knife points) of the blade, the convex lugs arranged on the periphery of the circular blade body correspondingly effectively support the knife points to shred paper, thereby increasing paper shredding efficiency of the knife points of the paper shredder blade.
Description
Technical field
The utility model relates to shredder, especially a kind of high cataclasm rate kneader bar.
Background technology
As everyone knows, cutter for paper grinder is by a pair of cylindrical shape hobboing cutter bar construction that rotates in rightabout.Cylindrical shape hobboing cutter rod is assembled by axostylus axostyle and most break bars that are placed on the axostylus axostyle, break bar then by and the two secondary kneader bars that are close together constitute.Existing kneader bar comprises that periphery is provided with the circular lamellar body 2 of the outer point of a knife 1 that stretches out as shown in Figure 1, and circular lamellar body 2 centers are provided with the axle center hole 3 that cooperates with axostylus axostyle.Kneader bar is fixed on the cutter shaft 4 of shredder by axle center hole 3, when cutter shaft 4 rotations, kneader bar rotates synchronously, after the periphery sword that rotates in rightabout two circular lamellar bodies 2 is with paper 6 cutting sliverings, by the point of a knife 1 of the circular lamellar body 2 peripheries paper scrap that breaks in rotary course.Because the point of a knife 1 of circular lamellar body 2 peripheries is in the paper scrap process that breaks, the lower end of being pricked disconnected paper 6 is in hanging shape, 1 pair of paper 6 of point of a knife breaks and carries out under the corresponding support of nothing, the impulsive force of 1 pair of paper of point of a knife during kneader bar rotates by means of high speed fully to breaking of paper.Therefore, can reduce the efficient that breaks of paper greatly.Secondly, can fully prick disconnected paper scrap for satisfying point of a knife 1, improve the cataclasm rate of being pulverized paper, can strengthen or thicken the point of a knife 1 of circular lamellar body 2 peripheries usually, this can make the cutter for paper grinder structure increase, and finally can be directed at the shredder overall structure and strengthen.This undoubtedly can increase equipment material and manufacturing cost.
Summary of the invention
Technical problem to be solved in the utility model is to remedy above-mentioned the deficiencies in the prior art, under the situation that does not strengthen the point of a knife outside dimension, designs the high cataclasm rate kneader bar that a kind of cataclasm rate that can satisfy shredder requires.
The utility model is solved by the following method.
This height is cataclasm rate kneader bar comprises: periphery is provided with the circular lamellar body of the outer point of a knife that stretches out, and circular lamellar body center is provided with the axle center hole that cooperates with axostylus axostyle.
The characteristics of this height is cataclasm rate kneader bar are:
Described circular blade peripheral edge is provided with a lug that highly is lower than point of a knife at least.
Technical problem of the present utility model is further solved by the following technical programs.
Described lug is arranged on the circular blade peripheral edge of two point of a knife spacers.
Described lug that quantity is set is corresponding with the point of a knife number of circular blade peripheral edge.
The nose of described lug is an arc surface.
The beneficial effect that the utility model is compared with the prior art is:
This height is cataclasm rate kneader bar is under the condition that does not change blade maximum outside diameter (point of a knife place) specification, by the mode of lug is set at circular lamellar body peripheral region, provide corresponding effective support for point of a knife breaks to paper, thereby improve the break efficient of the point of a knife of kneader bar paper.
Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is traditional kneader bar structural representation;
Fig. 2 is the structural representation of high cataclasm rate kneader bar;
Fig. 3 is the cataclasm rate kneader bar of a height shown in Figure 2 working state schematic representation.
The specific embodiment
The basic structure that can be clear that high cataclasm rate kneader bar from Fig. 2 is identical with existing kneader bar, comprising: periphery is arranged with the circular lamellar body 2 of two points of a knife that stretch out 1 outward, and circular lamellar body 2 centers are provided with the axle center hole 3 that cooperates with axostylus axostyle.Difference is: be arranged with two lugs 5 that highly are lower than point of a knife 1 on the periphery at 2 liang of point of a knife 1 intervals of described circular lamellar body.The nose of described lug is an arc surface.
The course of work of this high cataclasm rate kneader bar on a pair of cylindrical shape hobboing cutter rod that rotates in rightabout be as shown in Figure 3: open 6 when waste paper and enter between the two hobboing cutter rods from the top, after the periphery sword that rotates in rightabout two circular lamellar bodies 2 is with paper 6 cutting sliverings, the point of a knife 1 that is symmetricly set on circular lamellar body 2 peripheries is in the paper scrap that breaks, the lug 5 that is symmetricly set on circular lamellar body 2 peripheries on the opposite cutter shaft 4 can support the corresponding position that withstands paper 6, paper 6 can be given full play to the ability that breaks of 1 pair of paper of point of a knife under the skill support effect of lug 5, and then improves the cataclasm rate of cut paper of shredder.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
Claims (4)
1. one kind high cataclasm rate kneader bar comprises: periphery is provided with the circular lamellar body of the outer point of a knife that stretches out, and circular lamellar body center is provided with the axle center hole that cooperates with axostylus axostyle, it is characterized in that:
Described circular blade peripheral edge is provided with a lug that highly is lower than point of a knife at least.
