Abstract

The invention relates to a device (1a..1g) for processing thermoplastic material, comprising a storage container (2) / a conveying line (11) for pieces of plastic particles and a conveying screw (3) connected thereto. The device further comprises (1a.. 1g) an extruder (4) which connects to the conveying screw (3), and a temperature control device (7) arranged in the course of the conveying screw (3). In addition, a temperature sensor (8, 8a, 8b) is arranged in the course of the conveying screw (3) / the extruder (4), and/or means (10) are provided for detecting a load of a drive (6) of the extruder (4). Finally, the device (1a..1g) comprises means for influencing the temperature control device (7) and a control/regulation unit (9) which is connected to the at least one temperature sensor (8, 8a, 8b) and/or the influencing means of the temperature control device (7). Furthermore, an operating method for the device (1a.. 1g) is specified, in which the pieces of plastic particles are temperature-controlled by a temperature control device (7) in the course of the conveying screw (3).

Description

technical field [0001] The invention relates to a plant for processing thermoplastic materials, said plant comprising a storage container for holding bulk plastic granules or a conveying pipeline for conveying lumpy plastic granules, which is connected to the storage vessel / conveying pipeline at a transfer port A screw conveyor attached and an extruder attached to the screw conveyor. Furthermore, the invention also relates to a method for operating the above-mentioned device. Background technique [0002] Devices and methods of the above-mentioned type are known in principle from the prior art. For example, EP 0 934 144 B1 discloses a device for processing thermoplastic materials in this regard. The equipment consists of a machine housing with a feed hopper and a driven slide that presses the plastic material to be processed on a floor into a processing drum or conveying pipe. The blades are mounted helically on the processing drum. The blade and the screw conveyor immed...
