Installation for preparing and further processing a thermoplastic material and method for operating said installation

摘要

Screw compounding machine driven by an electric motor is combined with a metering unit driven by motors. A following processing unit has a drive unit which operates intermittently for a specific period. A control unit linked to both motors and the molding machine drive unit operates the motors for the compounding machine and metering unit for the same period as the molding press. Screw compounding machine (1) driven by an electric motor (6) is combined with a metering unit (10,14) driven by motors(12,15). A following processing unit (26) has a drive unit (28) which operates intermittently for a specific period. A control unit (29) linked to both motors and the molding machine drive unit operates the motors for the compounding machine and metering unit for the same period as the molding press. An Independent claim is also made for the plant operation process in which the screw drive motor (6) and the metering motors (12,15) are controlled for the same cycle time as the processing unit. compounder (26).
