摘要：An underwater pelletizer cutting system allowing fine adjustments of therelative spacial relationship between an extrusion die and the blades of a cutting
assembly. The cutting assembly, which may be self-aligning in nature, is borne on the endof a drive shaft driven by a motor mounted on a carriage. The carriage is moveablerelative a fixed frame by a servomotor driving a ball screw. The ball screw, which
preferably has zero backlash, has a shaft attached at one end to the carriage for movingthe carriage. A PLC control system may be provided to accept inputs from an operatorand to run a cutting program, providing appropriate signals to the servomotor toadvance the cutting assembly as needed as the blades of the cutting assembly wear. ThePLC system may receive signals from a measuring system adapted to measure thecontact pressure between the cutting assembly and the face of the extrusion die.
