Abstract
An extruder arrangement for viscous material, especially rubber or natural or synthetic rubber mixtures, is provided. It has a screw extruder (12) with an extruder screw (16) that in the direction of conveying is followed downstream by a conveying device. The conveying device is a planetary pump (18), the outer ring (22) of which is rotatably supported.
Claims10
Extruder arrangement for viscous material, especially rubber or natural or synthetic rubber mixtures, including a screw extruder (12) having an extruder screw (16) which, in a direction of conveyance, is followed downstream by a conveying device, characterized in that the conveying device is a planetary pump (18) the outer ring (22) of which is rotatably mounted.
Extruder arrangement according to one of the preceding claims, characterized in that the central gear (20) of the planetary pump (18) is fixedly connected with the extruder screw (16).
Extruder arrangement according to one of the preceding claims, characterized in that the outer ring (22) is coupled with a brake.
Extruder arrangement according to one of the preceding claims, characterized in that the outer ring (22) is provided with a separate drive, which is controllable.
Extruder arrangement according to one of the preceding claims, characterized in that a pressure sensor is provided at the input side of the planetary pump (18) and is connected to a control device that controls the rotation of the outer ring (22).
Extruder arrangement according to one of the preceding claims, characterized in that the planetary pinions (26 to 30) are mounted from the intake side and the planetary carrier (24) is provided with recesses (36,38, and 40) through which the viscous material can flow.
Extruder arrangement according to one of the preceding claims, characterized in that the helical gearing has an angle of 10 to 60 degrees, preferably somewhat greater than 20 degrees.
