Description

"Stranr@presse für plastische Massen. Die sogenannten Schnecken- oder Schlauchpressen .enthalten be'lcanntlich ein als Schnecke gestaltetes Transport-. Knet- und Plastizierungsorgan, welches in einem die Schnecke umschließenden. Arbeitszylinder so gelagert ist, daß die Schnecke eine zuverlässige und reibungsmindernde Lagerung nur dort besitzt, wo das zu behandelnde Material in den Arbeitszylinder einfließt, während im übrigen die Schnecke nur durch die Berührung der Außenfläche ihrer Gänge mit der Zylinderinnenwandung gegen seitliche Kräfte gestützt wird. Die beim Arbei-ggang auftretenden recht beträchtlichen Reibungskräfte rufen einerseits einen .erheblichen Widerstand hervor, der die Antriebsäraft für :die Maschine in nutzloser Weise erhöht, anderseits entsteht eine verhältnismäßig starke Abnutzung an den erwähnten führenden Flächen zier Arbeitsteile, woraus ein Unruhelaufen und Schlagen der Schnecke im Zylinder resultiert."Stranr @ press for plastic masses. The so-called screw or Hose presses are known to contain a transport conveyor designed as a screw. Kneading and plasticizing organ, which in one surrounding the screw. Working cylinder is mounted in such a way that the worm has a reliable and friction-reducing mounting only possesses where the material to be treated flows into the working cylinder, while the rest of the snail only by touching the outer surface of its flights is supported with the cylinder inner wall against lateral forces. The one at work Occurring quite considerable frictional forces on the one hand cause a considerable Resistance, which uselessly increases the driving force for: the machine, on the other hand, there is a relatively strong wear and tear on the leading ones mentioned Surfaces decorate working parts, from which a balance running and beating of the snail in the Cylinder results.

Erfindungsgemäß werden diese Nachteile außerordentlich einfach dadurch beseitigt, daß die Schnecke am Austrittsende der Presse eine einwandfreie Lagerung, zweckmäßig ein Kugel-oder Rollenlager, erhält.According to the invention, these disadvantages become extremely simple as a result eliminates the problem that the screw at the outlet end of the press is properly supported, appropriately a ball or roller bearing is obtained.

Die neue Lagerung besitzt den besonderen Vorteil, daß dir: Berührung oder Stützung zwischen der zylindrischen Umfläche der Schnekkengänge und der Innenwandung des Arbeitszylinders überhaupt entbehrlich und zwischen diesen Teilen ein radiales Spiel eingeschaltet wird, so daß hierdurch auch eine ganz erhebliche Herabsetzung der Reibungsarbeit beim Betrieb entsteht.The new storage has the particular advantage that you: touch or support between the cylindrical outer surface of the screw flights and the inner wall of the working cylinder is dispensable at all and a radial one between these parts Game is switched on, so that hereby also a very considerable reduction the friction work occurs during operation.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt: Abb. i einem achsialen Längsschnitt von Arbeitszylinder und Schnecke und Abb. z einen Schnitt nach A-A der Abb. i. Am Austrittsende der Schnecke ist letztere abgesetzt und hier ein reibungsminderndes Lager eingeschaltet, welches :durch Kugeln oder Rollen gebildet ist. Zwischen dem Arbeitszylinder und den Schneckengängen besteht ein geringes radiales Spiel, so daß sich die Schnecke auf ihre ganze Länge, soweit sich die Schneckengänge erstrecken, vollkommen frei im Arbeitszylinder drehen kann.In the drawing, an embodiment of the invention is shown, namely shows: Fig. i an axial longitudinal section of the working cylinder and screw and Fig. z a section along A-A of Fig. i. At the exit end of the screw is the latter discontinued and switched on a friction-reducing bearing, which : is formed by balls or rollers. Between the working cylinder and the worm flights there is a slight radial play, so that the worm extends over its entire length, as far as the worm threads extend, rotate completely freely in the working cylinder can.
