Abstract
A blade structure of shredder is composed of a pair of columnar hobs, each columnar hob comprises a polygon axle and a plurality of break blades sheathed on the axle. The break blades, each composed of two sets of secondary blades, are assembled on the two columnar hobs in an interlaced manner. The secondary blade which is wholly relatively thin is convexly provided with a ring of raised loops therein to improve the thickness of the blade. Two secondary blades are connivently connected through the raised loops to form a break blade. Thus, the break blade is relative light by weight with more than half material saved. Furthermore, the cutting edge of each secondary blade formed by planishing a multi-layer edge, which has being folded so as to increase the thickness, into a bevel and trimming the bevel is wholly thicker than the regular cutting edge. As a result, it is difficult for paper to clamp and more easy to cut off during a paper cutting operation.
Description
Technical field
The utility model is relevant for a kind of shredder structure, refers to a kind of can easily paper being blocked especially and is difficult for the blade structure of the shredder of holding paper.
Background technology
Consult shown in Figure 1, the cutter for paper grinder of traditional type be by two cylindrical shape hobboing cutters 1,1 ' constitute, each hobboing cutter comprises polygonal axostylus axostyle 2, and several are sheathed on the offset blade 4 on this axostylus axostyle, and it is spaced apart with it to be provided with a packing ring 6 between two adjacent offset blades 4, makes that the offset blade 4 on the two cylindrical shape hobboing cutters is assembled in staggered mode.As shown in Figure 2, each offset blade 4 is back-to-backly constituted by the auxiliary-blade 4a that puts by two groups, and have a plurality of sword 4b that block on each auxiliary-blade 4a periphery, and when the sword 4b that blocks of shredder carries out paper when blocking operation, the blocking sword 4b and can block paper simultaneously of blade, sheet-fed more easily blocks, when many paper is desired to block, need bigger shaft horsepower, and noise is bigger, the strength that the shredder driven wheel is born is relatively large, and the tooth on the gear has the anxiety that breaks.
In view of this utility model people accumulates and is engaged in the industry experience for many years, is study intensively and test improvement repeatedly, nowadays creates a kind of novel kneader bar finally, and the habitual product shortcoming of can forgoing is to promote effect.
Summary of the invention
Main purpose of the present utility model is to provide a kind of blade structure of shredder, it can effectively overcome the above-mentioned defective of traditional structure, when shredder carries out shredded paper Zhang Zuoye, the shaft horsepower that needs is less, noise is less, and the strength that driven wheel bore is less relatively, the weight of offset blade gentlier and only needs half following material of former shredder auxiliary-blade, is difficult for holding paper and can carries out paper swimmingly and block operation.
Technical solutions of the utility model:
A kind of blade structure of shredder, it comprises two cylindrical shape hobboing cutters that can rotate round about, each hobboing cutter comprises a polygonal axostylus axostyle, and several are enclosed within the offset blade on this axostylus axostyle, has pad between adjacent offset blade, offset blade on the two cylindrical shape hobboing cutters fits together interlacedly, wherein each offset blade is constituted by the auxiliary-blade of putting by two groups, have on the auxiliary-blade periphery of each offset blade and one or morely block sword, it is characterized in that by what the auxiliary-blade periphery outwards protruded out:
The inboard of the auxiliary-blade of offset blade is protruding with one in order to the thick circle bulge loop of bed hedgehopping cutter, and two groups of auxiliary-blades by the offset blade put abut against on the bulge loop; The blade that blocks sword by the multilayer blade folding thicken to flatten become the oblique angle and constitute.
The utility model mainly each auxiliary-blade with cutter for paper grinder offset blade is thinner, and two auxiliary-blades utilize bulge loop that bulge loop is abutted against becomes one group of offset blade, thereby saves cost; And block sword and utilize folding pressing of multilayer blade to form for the oblique angle cuts deburring again, so still more abundant.
The utility model beneficial effect: according to said structure, the utility model has reached the defective that effectively overcomes traditional structure, when shredder carries out shredded paper Zhang Zuoye, the shaft horsepower that needs is less, noise is less, and the strength that driven wheel bore is less relatively, the weight of offset blade gentlier and only needs half following material of former shredder auxiliary-blade, is difficult for holding paper and can carries out the purpose that paper blocks operation swimmingly.
Understand in order to allow the auditor that the utility model is had further, Zi Zuo is as follows with graphic detailed description the utility model:

The specific embodiment
Consult shown in Figure 3, cutter for paper grinder of the present utility model be by two cylindrical shape hobboing cutters 10,10 ' constitute, each hobboing cutter comprises polygonal axostylus axostyle 12, and several are sheathed on the offset blade 14 on this axostylus axostyle, it is spaced apart with it to be provided with a pad 16 between the adjacent offset blade 14, makes that two offset blades 14 on the two cylindrical shape hobboing cutters 10,10 ' are assembled in staggered mode.As Fig. 4~shown in Figure 6, each offset blade 14 is back-to-backly constituted by the auxiliary-blade 14a that puts by two groups, be respectively equipped with one group of above sword 14b that blocks on each group auxiliary-blade 14a periphery, two groups can be blocked paper by the corresponding sword 14b that blocks on the auxiliary-blade 14a that puts.Principal character of the present utility model is:
The auxiliary-blade 14a integral thickness attenuation of each offset blade 14 (than traditional type auxiliary-blade thin 1/2 even littler), the inboard of each auxiliary-blade 14a is convexly equipped with a circle bulge loop 14c, but this bulge loop 14c is thick except bulk strength and the bed hedgehopping cutter that can strengthen auxiliary-blade 14a, two groups are to utilize bulge loop 14c that bulge loop 14c is abutted against to form one group of offset blade 14 together by the auxiliary-blade 14a that puts, thereby save cost.
Moreover, the sword 14b point of a knife place of blocking of auxiliary-blade 14a is that the sword of multilayer is thick, its preparation method is mainly blocked the multilayer of general auxiliary-blade 14a folding earlier the thickening of sword 14b and is also flattened (14a is concordant with auxiliary-blade) afterwards, to block sword 14b point of a knife again and be pressed into the oblique angle, last deburring again is to excise unnecessary blade, form the abundant sword 14b that blocks, this blade that blocks the general shredder of sword 14b blade is thick, so it is powerful and be difficult for holding paper to cut paper.
In when operation, cutter for paper grinder of the present utility model is frustrated to paper and is utilized auxiliary-blade 14a outer rim blade that the paper scrap of each strip is blocked into sectional chip again by the sword 14b that blocks of the two offset blades 14 that are staggeredly set, to guarantee confidentiality.In addition, because the special structure design of cutter for paper grinder of the present utility model makes that all the auxiliary-blade 14a on the cutter 10 are all thinner thickness and block the more abundant structure of sword 14b blade; And two groups of hobboing cutters 10, when 10 ' two offset blades 14 are staggered, wherein an offset blade 14 block the bulge loop 14c back that sword 14b is against another offset blade 14 (two groups utilize bulge loop 14c against bulge loop 14c to form one group offset blade 14 by the auxiliary-blade 14a system of putting), thereby reach one high-quality, high efficiency, low noise and improve effect cheaply.
In sum, the blade structure of the utility model shredder has its novelty, can be effectively, positively eliminate the shortcoming of existing shredder, and be one to have the creation of practicality, creativeness and novelty concurrently.
