Abstract
The utility model discloses a novel paper shredder blade which comprises a metal blade body, wherein a sleeving hole is formed in the metal blade body; a metal spacer bush is arranged at the edge of the sleeving hole in the front surface of the metal blade body; a paper shredding blade tip is convexly arranged on the circumferential surface of the metal blade body; a paper shredding blade edge is arranged at the joint between the front blade surface of the paper shredding blade tip and the front surface of the metal blade body; an inclined surface is arranged at the top end of the paper shredding blade tip; a pushing bulge is arranged on the inner wall of the sleeving hole of the metal blade body. According to the novel paper shredder blade, the metal blade body is integrated with the metal spacer bush, and during operation, a rotary shaft of a paper shredder does not need to be sleeved with a plastic spacer bush, namely that two adjacent paper shredding blade groups can be spaced through a metal spacer bush; the pushing bulge is arranged, so that the rotary shaft can be stably sleeved with the metal blade body and the metal spacer bush, the metal blade body can not slip during paper shredding, and the stable reliability is good. The novel paper shredder blade has the advantages of being novel in structural design, good in stable reliability and capable of effectively simplifying the rotary shaft structure of the paper shredder.
Description
Technical field
The utility model relates to shredder technical field, relates in particular to a kind of new-type kneader bar.
Background technology
In enterprise's office, the paper that was much used and cancelled, because the data of recording is above comparatively responsive, for preventing that other people from obtaining the data of recording on file, this just need to carry out pulverization process by paper, and shredder arises at the historic moment.
Shredder mainly completes shredded paper operation by the blade being installed on turning cylinder, and multiple blade for shredding paper groups are installed on turning cylinder, each blade for shredding paper group is just forming arranging and spell the blade for shredding paper being against together by two, for making two adjacent blade for shredding paper groups spaced apart, rotating shaft is moved between two adjacent blade for shredding paper groups and is set with plastic cement spacer.
For above-mentioned shredder, because plastic cement spacer more easily damages compared with blade for shredding paper, this just makes the maintenance rate of shredder very high.
Summary of the invention
The purpose of this utility model is to provide a kind of new-type kneader bar for the deficiencies in the prior art, and this new-type kneader bar structural design novelty, reliability are good and can effectively simplify the structure of shredder turning cylinder.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of new-type kneader bar, include the metal blade body of rounded shape, the center of metal blade body offers the suit hole of running through completely and matching with shredder turning cylinder, the front of metal blade body is provided with along the direction extension of suit axially bored line and is circular metal spacer, metal spacer and this body by integral forming of metal blade in the edge part in suit hole;
The periphery of metal blade body convexes with at least two shredded paper points of a knife that are circumference ring-type even interval layout and difference shape triangular in shape, the junction in the rake face of each shredded paper point of a knife and metal blade body front is respectively arranged with shredded paper blade, and the top ends of each shredded paper point of a knife is provided with respectively the inclined-plane that makes the top ends of shredded paper point of a knife be tetrapyamid shape;
The suit hole inwall of metal blade body is provided with cross section shape triangular in shape and is the equally distributed card convex of supporting of circumference ring-type and rises, and respectively supports card convex and plays the outer face that extends to respectively metal spacer from the back side of metal blade body.
The beneficial effects of the utility model are: the new-type kneader bar of one described in the utility model, it comprises metal blade body, metal blade body is offered suit hole, metal blade body front arranges metal spacer in suit bore edges portion, metal spacer and this body by integral forming of metal blade, metal blade body periphery is convexly equipped with shredded paper point of a knife, the junction in shredded paper point of a knife rake face and metal blade body front arranges shredded paper blade, end, paper shredding blade pinnacle arranges inclined-plane, metal blade body suit hole inwall arranges cross section shape triangular in shape and is the equally distributed card convex of supporting of circumference ring-type and rises.Metal blade body and metal spacer are designed to integrative-structure by the utility model, and in the time that the utility model is installed on shredder turning cylinder, turning cylinder is without being inserted in plastic cement spacer again, and adjacent blade for shredding paper group can realize by metal spacer spaced apart; Rise and can make metal blade body and metal spacer stably be inserted in turning cylinder to card convex, when shredded paper, metal blade body there will not be the phenomenon of skidding, and reliability is good.Design by said structure, the utlity model has structural design novelty, reliability good and can effectively simplify the advantage of shredder rotation shaft structure.
Brief description of the drawings
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing does not form any restriction of the present utility model.
