Abstract
A composite breaker bar of a cylindrical shredder hob is composed of two pairs of cutting edge rings arranged with truncating edge on the outer ring and a plastic base ring arranged with a spacer sleeve. The center of the plastic base ring is provided with an axial center hole which can be engaged and mounted with a polygonal shaft lever. Two pairs of the cutting edge rings are installed on the plastic base ring and embedded together after being combined. Two cutting edge rings that construct the breaker bar are preinstalled on the plastic base ring with the spacer sleeve to form a group of shaped hobs with the spacer sleeve, therefore the two blades and the spacer sleeve need to be installed separately before integrated to be one component, and the assemble process of the cylindrical hob is simplified. As the cutting edge ring and the plastic base ring are of engaged structure and the body of the blade is replaced with plastic base ring made of lightweight material, the usage of steel can be reduced without affecting the original paper cutting function of the hob. Therefore the steel consumption and the weight of the hob are reduced, and the integral weight of the cylindrical hob after assembly is further reduced.
