- the stenter is around a horizontal by means of a stenter drive Tensioning frame rotation axis rotatable.
- a turntable drive is used the one here for a turntable from the stenter drive via a Gear is derived.
- the other turntable which is designed to be extendable, is rotated with a clamped mix container.
- the jig, d. H. the mutual adjustment of the turntable is with the help of a arranged on the clamping frame and rotating with this clamping drive controllable as an electric motor.
- the individual drives are either controlled by a control device Manual, externally controlled or in a program sequence when available certain switch-on and switch-off conditions, in particular via limit switches and position switches are specified.
- the well-known pull-out device for a turntable as well as the door the mixer housing are operated by hand, which is a certain Power and time required with a risk that cannot be excluded of operating errors.
- the object of the invention is a generic To further develop biaxial mixers in such a way that functional reliability and ease of use increase.
- a co-rotating drive motor is on the stenter attached for the puller.
- the drive motor is over the already existing control unit by using existing Components or additions familiar to a specialist controlled.
- control unit and thus the drive motor for the pull-out device by hand or in a larger mixing line with several devices also done externally can be used independently of other mixing programs, for example as pure manual control can be provided for the pull-out device.
- a manual switch via an initialization switch Establishment of a basic program position required, whereby by hand For example, the turntable should be extended once at the beginning of a working day and remains at the end of a working day by hand is retracted in the housing.
- the mixing process takes place program-controlled automatically.
- the Mixing container placed and the mixing process by hand or externally controlled started with a program start switch.
- an automatic door control claimed below the but can also be done by hand in a simple version can.
- the mixing process runs automatically after starting that the turntable retracted and the housing door closed becomes.
