Cutter holder device in a pelletizer.

摘要

A cutter holder device for a pelletizer in which a cutter shaft (1) is coupled to a cutter holder (3) through a crowned involute spline gear (2) and an elastic member (30a) so that cutter blades (6) are kept in close contact with a die surface (8a). In the cutter holder device, the cutter shaft is coupled to the cutter holder through the crowned involute spline gear and the elastic member, to allow for misalignment of the shaft, while keeping the cutter blade in close contact with the die surface.
