Abstract
The utility model relates to office equipment, in particular to a crusher with A-shaped cutters. In the crusher, the A-shaped cutters are arranged in groups, each of the A-shaped cutters is formed by splicing a left cutter blade and a right cutter blade, each of the left cutter blade and the right cutter blades is provided with a through hole for being installed on a rotation shaft, and 'A' shapes are formed between first cutter points of the left cutter blade and second cutter points of the right cutter blade. In the crusher, with the adoption of the A-shaped cutters, when the left cutter blade and the right cutter blade are used for cutting a plurality of pieces of paper, the force born by each cutter blade (left cutter blade or the right cutter blade) is reduced, the probability of deformation of the cutter points is reduced; and as the force born by the cutter points of the cutter blades is reduced, the load for a gear transmission system is reduced, and the occurrence that scraps of paper are blocked between the cuter blades is reduced.
Description
Technical field
The utility model relates to a kind of office equipment, especially a kind of shredder of A word cutting knife.
Background technology
Cutting knife is the movement important component part of shredder, and the excellence of cutting edge is directly connected to the cut paper quality and the cut paper ability of shredder, and the form of the splicing of cutting edge also is one of important embodiment of cut paper quality and ability.
At present, the cutting knife that common powder is cut is that left and right two cutting edges are stitched together, and the point of a knife of the point of a knife of left cut blade and right cut blade forms " V " font.The monolithic cutting edge that powder is cut (left cut blade or right cut blade) is generally all very thin, the intensity of its point of a knife a little less than, and point of a knife intensity is not strengthened, in the cut paper process, point of a knife is stressed very big, is prone to produce distortion, thereby influences cut paper quality and ability.The flatness of general cutting edge can not be accomplished absolute flat, during with the cutting knife cut paper of the shredder of V word cutting knife composition, has the slit; Have paper scrap and be stuck between two cutting edges, go down for a long time, cutting edge meeting spreading; The length cutting knife can produce interference in the running, causes the cutting knife damage.
The utility model content
The technical problem that the utility model will solve is: based on the problems referred to above; Provide a kind of monolithic power that cutting edge is shared little; The probability of point of a knife distortion is low, and the load of gear train assembly is little, and paper scrap is stuck in the obviously shredder of the A word cutting knife of minimizing of two phenomenons between the cutting edge.
The utility model solves the technical scheme that its technical problem adopted: a kind of shredder of A word cutting knife; Has the A word cutting knife of arranging by group; Described A word cutting knife is made up of left cut blade and the splicing of right cut blade; Left cut blade and right cut blade are provided with the through hole that is installed on the turning cylinder, become " A " font between first point of a knife of left cut blade and second point of a knife of right cut blade.
For guaranteeing the intensity of monolithic cutting knife, the left cut blade and the right cut blade of said A word cutting knife are stamping forming.
The beneficial effect of the utility model is: the utility model adopts A word cutting knife, and left cut blade and right cut blade are when cutting the as much paper, and the power that single piece blade (left cut blade or right cut blade) is shared will reduce, thereby has reduced the probability of point of a knife distortion; Because stressed the reducing of point of a knife of cutting edge also will reduce the load of gear train assembly, adopt A word cutting knife also will reduce paper scrap and be stuck in two phenomenons between the blade.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the A word cutting knife of the utility model.
Fig. 2 is the structural representation of V word cutting knife.
Fig. 3 is the structural representation of the shredder cutting knife formed of the A word cutting knife of the utility model.
Among the figure: 1. left cut blade, 2. right cut blade, 3. through hole, 4. first point of a knife, 5. second point of a knife.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A word cutting knife as shown in Figure 1; It is made up of left cut blade 1 and 2 splicings of right cut blade; Left cut blade 1 or right cut blade 2 are provided with the through hole 3 that is installed on the turning cylinder, become " A " font between first point of a knife 4 of left cut blade 1 and second point of a knife 5 of right cut blade 2.
V word cutting knife as shown in Figure 2 is stitched together by left and right two cutting edges, and the point of a knife of the point of a knife of left cut blade and right cut blade forms " V " font.The cutting knife of the shredder of being made up of V word cutting knife is in the cut paper process, and point of a knife is stressed very big, is prone to produce distortion, thereby influences cut paper quality and ability.
The cutting knife of the shredder that is arranged in by group by A word cutting knife as shown in Figure 3, in the shredded paper process, the power that single piece blade (left cut blade 1 or right cut blade 2) is shared is little, thereby has reduced the probability of point of a knife distortion; Because stressed the reducing of point of a knife of cutting edge also will reduce the load of gear train assembly.
Further, for guaranteeing the intensity of monolithic cutting knife, the left cut blade 1 and the right cut blade 2 of said cutting knife are stamping forming.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
Claims (2)
1. the shredder of an A word cutting knife; Has the A word cutting knife of arranging by group; It is characterized in that: described A word cutting knife is made up of left cut blade (1) and right cut blade (2) splicing; Left cut blade (1) and right cut blade (2) are provided with the through hole (3) that is installed on the turning cylinder, become " A " font between first point of a knife (4) of left cut blade (1) and second point of a knife (5) of right cut blade (2).
2. the shredder of a kind of A word cutting knife according to claim 1 is characterized in that: the left cut blade (1) and the right cut blade (2) of said A word cutting knife are stamping forming.
