Abstract

The invention discloses a combined structure blade of a paper shredder, which particularly relates to a combined structure blade of a paper shredder which is made from two kinds of materials and can reduce the blade cost and the paper shredder cost, and a preparation method thereof. The combined structure blade comprises a blade which is positioned at periphery and has a cutting blade and a base ring positioned inside the combined structure blade, the center of the base ring is an axis hole which can match various shapes of axial rods, wherein, the blade is made from metal material, the base ring is made from high polymer material, the blade and the base ring are integrated by injection molding. The combined structure blade is characterized in that the blade consists of a multi-segment arc blade which can surround a circle of the base ring, the multi-segment arc blade separates a breaking point along the periphery of a complete unbroken original blade, the breaking point is positioned below the tip of the cutting blade and reaches the intersection point between the connecting line of the tip of the cutting blade and the axis and the periphery of the original blade, and the quantity of the multi-segment arc bade is same as that of the cutting blade on the blade.

Description

technical field [0001] The invention relates to a cutter used in a paper shredder, in particular to a combined structure blade of a paper shredder which is composed of two kinds of materials and can reduce the cost of the blade and the cost of the whole machine, and a manufacturing method of the combined structure blade. technical background [0002] The patent document with the patent number 200610033714.8 discloses a combined structure blade of a shredder cylindrical hob, which is characterized in that: the blade is composed of a steel sheet with a cut-off edge and a plastic sheet for positioning the steel sheet. The base ring is composed of; the center of the plastic base ring is provided with an axial hole that can be matched with a polygonal shaft; the steel sheet is glued on the periphery of the plastic base ring. This technology minimizes the amount of steel used on the blade, and replaces the blade body with a plastic base ring made of light-weight materials. It will...
