Embodiment Construction

[0023] In the exemplary embodiment shown in FIG. 1 , a device for processing material, in this case plastic, is shown. The device comprises an extruder, wherein the extruder has two screws 1 , 2 for plasticizing the plastic. The screws 1 , 2 are mounted rotatably in a housing 3 , which in this case is designed as a barrel. Furthermore, the screws 1 , 2 can be driven by a drive (not shown), wherein the screws 1 , 2 and the drive can be coupled via two transmission elements, also not shown.

[0024] According to the invention, the transmission element is designed in this exemplary embodiment in such a way that the screw 1 , 2 can be exchanged with respect to its position and / or the direction of rotation of the screw 1 , 2 can be reversed. In this embodiment, each screw 1 , 2 can be coupled to the drive at different positions via each transmission element.

[0025] The drive, not shown, includes an electric motor and a gear that can be operated in both directions of rotation. ...

Abstract

The invention relates to a device for processing a material, for example, plastic, rubber or similar, with an extruder, whereby the extruder comprises at least two screws (1, 2) for processing the material. Said screws (1, 2) are mounted to rotate in a housing (3) and are driven by at least one drive. Transmission elements for transmission of the force between the screws and the drive are provided. According to the invention, the service life of the housing (3) may be improved, whereby the screws (1, 2) are embodied to be exchangeable with regard to the position thereof and / or the direction of rotation of the screws (1, 2) may be reversed. Furthermore, a method for operation of a device for processing a material and a gearbox for application with the device for processing a material are disclosed.

Description

technical field [0001] The invention relates to a device for processing materials, such as plastics, rubber or the like, with an extruder, wherein the extruder has at least two screws for processing the material, wherein the screws are rotatably mounted in a housing And it can be driven by at least one drive device, and a transmission element for transmitting force between the screw and the drive device is arranged therein. The invention also relates to a method for operating a plant for processing material, wherein the screw is coupled to a drive via at least one transmission element, wherein the screw is run in a first direction of rotation via the drive, and wherein the material processing is stopped . Furthermore, the invention relates to the transmission used, wherein the transmission has at least one gear wheel and / or at least one pinion for force transmission. Background technique [0002] Plants for processing materials with extruders have long been known in practi...
