Abstract
A paper shredder blade with an improved structure comprises a blade body and a blade point extending towards the periphery from the blade body. The blade point is arranged on the outer rim of the blade body, an installation hole is arranged in the middle of the blade body, the blade point comprises a first blade point and a second blade point, one end of the first blade point is connected with the blade body, the other end of the first blade point is connected with the second blade point, and the second blade point is bent along the rotation direction of the blade body. Due to the fact that the second blade point is bent along the rotation direction of the blade body, the second blade point pricks paper in advance, area and thickness of the blade can be reduced, furthermore the second blade point pricks paper surfaces vertically, and shredding efficiency is high.
Description
Technical field
The utility model relates to the shredder technical field, relates in particular to a kind of structure improved kneader bar.
Background technology
Existing kneader bar, the outer rim of blade forms some points of a knife, and point of a knife is used for puncturing paper in the shredded paper process; Point of a knife is an acute angle, and the inner side edge of point of a knife is a straight flange or arc limit, when point of a knife is pricked paper; The angle of point of a knife inner side edge and paper is acute angle, and cataclasm rate is not high, needs increase blade area and thickness to strengthen pricking paper intensity; Required driving force was bigger when point of a knife was pricked paper, and power demand is bigger during the shredder shredded paper.This blade cost is high, and makes shredder overall volume and weight increase.
The utility model content
The purpose of the utility model is to the deficiency of prior art a kind of structure improved kneader bar to be provided; Because second point of a knife is along the direction bending of blade body rotation; Second point of a knife is pricked paper in advance; Can reduce the area and the thickness of blade, and second point of a knife is vertically to prick paper, cataclasm efficient is high.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme.
A kind of structure improved kneader bar; Comprise blade body and the point of a knife that is extended outside by said blade body, said point of a knife is arranged at the outer rim of said blade body, and the middle part of said blade body offers installing hole; Said point of a knife comprises first point of a knife and second point of a knife; Said first point of a knife, one end is connected with said blade body, and the said first point of a knife other end is connected with said second point of a knife, and said second point of a knife is along the direction bending of said blade body rotation.
The side of the outer end of said first point of a knife is provided with an inclined-plane, and the outer end of said first point of a knife forms one and pricks paper portion.
That said second point of a knife is set to extend out along the direction of said blade body rotation and to the pointed cone portion that is used for pricking in advance paper of said blade body one side direction bending.
Angle between said first point of a knife and said second point of a knife is the obtuse angle.
Further, the medial surface of said second point of a knife is a curved surface.
Further, the medial surface of said second point of a knife is for facing directly.
Said point of a knife is provided with three.
Three said points of a knife are even settings of periphery along said blade body.
Wherein, the inwall of the installing hole in the middle part of the said blade body is provided with internal tooth.
Further, the installing hole in the middle part of the said blade body is set to polygonal hole.
The beneficial effect of the utility model: because the direction bending that second point of a knife of the utility model rotates along blade body, second point of a knife is pricked paper in advance, and the diameter of blade is littler, and blade its arm of force when pricking paper is littler, and power is littler during shredded paper, energy savings.
The second, under the situation with identical shredded paper effect, the area of producing the required sheet material of blade is littler, reduces the material use amount, reduces cost.
The three, the second point of a knife is vertically to prick paper, and point of a knife punctures paper more easily when shredded paper, and the paper bundle is disconnected, and cataclasm efficient is high.
