Mutual alignment and annexation
A blade, B blade lean on mutually by the one side that is provided with the convex closure muscle separately, and land leans on mutually, the seamed edge alignment of polygon through hole, and being superimposed with each other constitutes two-in-one double-edged blade group; Double-edged blade group cutting edge towards the knife pivot of paper crusher direction of rotation, is assembled on the polygon prismatic cutter shaft by the side set series connection of pad interval.
Operation principle
Because superimposed double-edged blade group has a differential seat angle in radial direction, point of a knife penetrates in the paper at different time during shredded paper, helps reducing the cutting resistance, avoids producing paper slip and twines; The optimization of cutting edge set of data parameter anterior angle, relief angle, transition cambered surface is adapted to the cutting and grinding to all kinds of paper, is convenient to chip removal, reduces the cutting resistance.
Beneficial effect
Optimize land anterior angle, relief angle, make land sharper, point of a knife can pierce through and catch on paper easily and avoid slippage, helps alleviating shredder live load energy consumption, improves shredded paper efficient; Thickening land thickness has strengthened land intensity, helps prolonging blade service life; The design of spoke shape convex closure muscle helps guaranteeing the mechanical strength and the flatness of blade integral body, has also simplified the punching out mould structure of blade simultaneously, has reduced the punching out die cost, has prolonged the service life of punching out mould.
Above-mentioned, the utility model adopts by two blades of A, B and is overlapped into the twolip sharp knife sheet that staggers before and after the blade tip, and the technical scheme of optimization cutting edge set of data structural parameters, the blade that has overcome the prior art shredder exists that load is heavy, energy consumption is big, noise is big, the problems and shortcomings of fragile, easy winding, the kneader bar of a kind of superimposed twolip that is provided, by reducing the cutting resistance, avoid producing the cutting paper slip and twine, make kneader bar work reach underload, energy-conservation, noise reduction, durable, the purpose of not twining.
