Die Erfindung betrifft eine zwei- oder mehrwellige Schneckenmaschine zum kontinuierlichen Aufbereiten, Mischen, Kneten, Entgasen und Extrudieren von plastischen Massen, insbesondere thermoplastischen Kunststoffmassen, bei welcher die zur jeweiligen S Massebehandlung unterschiedlichen Schneckenteile drehfest auf der Antriebswelle aufgesteckt und austauschbar sind. Der wesentliche Vorteil dieser Art Schneckenmaschinen ist, daß die Schneckenteile von ihrer Welle abgezogen und durch andere z. B. durch solche mit anderer Gewindesteigung, anderer Einzugswirkung, anderer Knet- und Mischwirkung oder anderer Auspreßwirkung ersetzt werden können. Beim Auswechseln der unter der Masseeinfüllöffnung der Maschine befindlichen und dem Masseeinzug in die Maschine dienenden Schneckenteile müssen jedoch erst alle anderen Schneckenteile von der Welle abgezogen und nach dem Auswechseln der dem Masseeinzug dienenden Schneckenteile wieder in entsprechender Folge aufgesteckt werden.The invention relates to a twin or multi-shaft screw machine for continuous processing, Mixing, kneading, degassing and extrusion of plastic materials, especially thermoplastics Plastic masses in which the screw parts that are different for the respective S mass treatment non-rotatably attached to the drive shaft and interchangeable. The main advantage of this type Screw machines is that the screw parts are withdrawn from their shaft and replaced by other z. B. by those with a different thread pitch, a different pull-in effect, a different kneading and mixing effect or other expressing effect can be replaced. When replacing the under the compound filler opening screw parts located in the machine and used to feed the mass into the machine However, only all other screw parts are removed from the shaft and after replacing the dem Mass feed serving screw parts are re-attached in the appropriate sequence.

Zur Behebung dieser Schwierigkeiten sind erfindungsgemäß die die Schneckenteile tragenden Wellen im Bereich der dem Masseeinzug in die Maschine dienenden Schneckenteile zweigeteilt und die jeweils zusammengehörigen Wellenstücke mittels eines von außen zugänglichen, * das eine Wellenstück längsdurchdringenden und im anderen Wellenstück fest angebrachten, beispielsweise fest angeschraubten Spannbolzens axial zusammenhaltbar eingerichtet. Dadurch wird erreicht, daß zum Auswechseln der an der Antriebsseite befindlichen Schneckenteile nicht erst alle anderen Schneckenteile von der Welle abgezogen werden müssen, sondern sie können mit dem ihnen zugehörigen Wellenstück im ganzen aus der Maschine entfernt werden, nachdem zuvor die an der Teilstelle der Welle vorgesehene axiale Verbindung gelöst worden ist.In order to overcome these difficulties, the shafts carrying the screw parts are according to the invention divided into two parts in the area of the screw parts serving to feed the mass into the machine and each Corresponding shaft pieces by means of an externally accessible, * longitudinally penetrating one shaft piece and firmly attached in the other shaft piece, for example firmly screwed on Clamping bolt set up so that it can be held together axially. This ensures that to replace the on the screw parts located on the drive side do not first pull all other screw parts off the shaft must be, but they can with their associated shaft piece in the whole of the Machine are removed after the axial connection provided at the part of the shaft has been resolved.

Ein Ausführungsbeispiel ist aus der Zeichnung ersichtlich. Dargestellt ist eine zweiwellige Schnekkenmaschine mit einer Mehrzahl von Schneckenteilen a, b, c, d, e. Die unter der Masseeinfüllöffnung 1 der Maschine befindlichen Schneckenteile α dienen dem Masseeinzug in die Maschine, die Schneckenteile δ zum Mischen und Kneten, die Schneckenteile c sind sogenannte Bremsgewinde zur Bestimmung der Verweilzeit im Wirkungsbereich der mischend und knetend sowie auch plastifizierend wirkenden Schnekkenteile b. Die Schneckenteile d unter der Öffnung 2 fördern die mittels der Schneckenteile b plastifizierte Masse mit relativ steilgängigem Gewinde von den Bremsschnecken c weg und nahezu drucklos zu den der Auspressung dienenden Schneckenteilen e hin. Da-Zwei- oder mehrwellige SchneckenmaschineAn exemplary embodiment can be seen from the drawing. A twin-screw screw machine is shown with a plurality of screw parts a, b, c, d, e. The screw parts α located under the mass filling opening 1 of the machine are used to feed the mass into the machine, the screw parts δ for mixing and kneading, the screw parts c are so-called brake threads to determine the dwell time in the area of action of the mixing, kneading and plasticizing screw parts b. The screw parts d under the opening 2 convey the mass plasticized by means of the screw parts b with a relatively steep thread away from the brake screws c and almost without pressure to the screw parts e used for pressing out.

bei ist ein Entgasen der Masse durch die Öffnung 2möglich. Von den zum Auspressen dienenden Schneckenteilen e wird die plastifizierte Masse durch ein Mundstück 3 ausgepreßt. Alle Schneckenteile α bis e sind auf die Antriebswellen 4 bzw. 4' drehfest aufgesteckt und am vorderen Ende der Wellen beispielsweise durch Kopfschrauben 5, 5' axial fest verriegelt. .at a degassing of the mass through the opening 2 is possible. The plasticized mass is pressed out through a mouthpiece 3 from the screw parts e used for pressing. All screw parts α to e are attached to the drive shafts 4 and 4 'in a rotationally fixed manner and are axially firmly locked at the front end of the shafts, for example by means of head screws 5, 5'. .

Zum einfacheren Auswechseln der dem Masseeinzug dienenden Schneckenteile α sind die Wellen 4 bzw. 4' im Bereich der dem Masseeinzug dienenden Schneckenteile α zweigeteilt, was in der Zeichnung an den mit χ bezeichneten Stellen deutlich erkennbar ist. Bei den durch die Zweiteilung sich ergebenden Wellenstücken sind in die einen die Spannbolzen 6 bzw. 6' eingeschraubt, die die anderen in axialen Bohrungen nach außen durchdringen. Mit Schraubmuttern 7 bzw. T oder irgendwelchen anderen an den freien äußeren Enden der Spannbolzen 6 bzw. 6' angebrachten Spannmitteln werden die Wellenstücke während des Betriebes der Maschine fest zusammengespannt und können zum Auswechseln der dem Masseeinzug dienenden Schneckenteile α ohne weiteres voneinander gelöst werden.For ease of replacement of the α serving the ground auger parts, the shafts 4 and 4 'in the field of serving the ground auger parts are α divided into two, which is clearly seen in the drawing to the designated points χ. In the case of the shaft pieces resulting from the division into two, the clamping bolts 6 or 6 'are screwed into one, which penetrate the other in axial bores to the outside. With screw nuts 7 or T or any other clamping means attached to the free outer ends of the clamping bolts 6 or 6 ', the shaft pieces are firmly clamped together during operation of the machine and can be easily detached from one another to replace the screw parts α used for mass collection.

Das Abziehen von und Wiederaufstecken auf die Welle ist nur noch für die tatsächlich auszuwechselnden Schneckenteile α erforderlich.Removing and re-attaching the shaft is only required for the screw parts α that are actually to be replaced.

Die Teilstellen und die Verspannungsmittel können, wenn notwendig, auch im Bereich anderer Schneckenteile der Maschine vorgesehen werden, bei- t spielsweise auch im Bereich der zum Mischen, Kneten und Plastifizieren dienenden Schneckenteile b. The sub-locations and the clamping means may, if necessary, the machine also be provided in the area of the other scroll members, examples t play, also in the field of serving for mixing, kneading and plasticizing screw parts b.
