Embodiment

[0015] Embodiment: From Fig. 3 and Fig. 4, it can be clearly seen that the lightweight blade 1 of the shredder cylindrical hob is provided with a knife body 11 with an outwardly protruding knife point 12 and a knife compound at the knife body The tip reinforcement layer 13 at the tip is formed. The center of the cutter body 11 is provided with an axial hole 14 that can be matched with the shaft.

[0016] The thickness of the blade tip reinforcement layer 13 is the same as that of the blade body 11 .

[0017] The blade tip reinforcement layer 13 is formed by bending, folding and flattening a sheet material which is reserved on the blade tip side of the blade body 11 and has the same thickness as the blade body 11 .

[0018] In order to improve the blade strength of the lightweight blade 1 of the present invention, concave and convex ring-shaped reinforcing grooves 15 and 16 are provided on the blade portion of the blade body 11 .

[0019] The cutter wheel that lightweight bla...

Abstract

A light blade set for the cylindrical rotor of paper breaker has a knife body with extended cutting tips on its periphery and a central hole matched with the shaft, and features that said cutting tip has a reinforcing layer for higher thickness and strength.

Description

technical field [0001] The invention relates to a paper shredder blade, in particular to a lightweight blade of a paper shredder cylindrical hob. Background technique [0002] As everyone knows, the existing paper shredder cutter is made of a pair of cylindrical hobs rotating in opposite directions. The cylindrical hob is assembled from a shaft and a plurality of cutter wheels that are sleeved on the shaft and spaced with gaskets, and the cutter wheel is composed of two pairs of blades that are close together. Existing blade as shown in Figure 1 and Figure 2, is an all-steel blade, and the periphery of blade is provided with a plurality of protruding knife points, and the center of blade is provided with the axis hole that can cooperate with polygonal shaft. In order to satisfy the matching of the knife tip parts when the two cylindrical hobs in opposite directions cut paper. The cutting edge protruding from the periphery of the blade usually needs to have a certain thickn...
