Description
BiBUOTHEKLIBRARY
Zum Verarbeiten von organischen plastischen Kunststoffen sind Schneckenpressen bekannt, in welchen die plastische Masse erweicht und gegenüber der Spritzform gestaucht wird. Diese Pressen bestehen aus einer oder mehreren Schnecken, die sich mit geringer Geschwindigkeit in einem mit einer Eintritts- und Austrittsöffnung versehenen Gehäuse drehen und, wenn mehrere Schnecken vorhanden sind, wechselseitig ineinandergreifen. Dabei ergeben sich je nach der Zähigkeit und der Adhäsionskraft des behandelten Stoffes hohe Axialdrücke an den Schnecken, welche durch Gegenstützlager aufgenommen werden.Screw presses are known for processing organic plastic plastics, in which the plastic mass softens and is compressed in relation to the injection mold. These presses exist consisting of one or more screws that move at low speed in one with an inlet turn the casing provided with the outlet opening and, if there are several screws, reciprocally interlock. Depending on the toughness and the adhesive force of the treated material high axial pressures on the screws, which are absorbed by counter support bearings will.
Durch diese hohen Axialdrücke, die eine ausreichende Schmierung der Lagerstellen erschweren oder vollständig verhindern, werden der Anlauf der Schnecken und ihre Umdrehung bei den bekannten Maschinen außerordentlich erschwert. Diese Nachteile machen sich besonders bemerkbar, wenn die im Betrieb befindlichen Maschinen vorübergehend angehalten und nach kurzer Pause wieder in Gang gesetzt werden, wodurch nach einer geringen Anzahl von Umdrehungen infolge der schlechten Reibungskoeffizienten in den Stützlagern die mechanische Leistung abnimmt.Due to these high axial pressures, which make adequate lubrication of the bearing points difficult or complete prevent the start of the screws and their rotation in the known machines extremely difficult. These disadvantages are particularly noticeable when the ones in operation Machines are temporarily stopped and restarted after a short break, whereby after a small number of revolutions due to the poor coefficient of friction in the mechanical performance of the support bearings decreases.
Gegenstand der Erfindung ist eine Schneckenpresse zum Verarbeiten plastischer Kunststoffe, bei welcher die erwähnten Nachteile dadurch vermieden sind, daß zwischen den zur Aufnahme der Axialdrücke dienenden Stützlagern der Schnecken und dem Gegenlager frei auf den Schneckenwellen drehbare, vorzugsweise gesondert angetriebene scheibenförmige Zahnräder angeordnet sind. Diese Zahnräder können mit beliebig hohen Drehzahlen, beispielsweise 1500 Umdrehungen in der Minute, umlaufen und dank ihrer schnellen Drehbewegung eine zwangläufige Schmierung zwischen den dem hohen Achsdruck unterworfenen Elementen aufrechterhalten. Das Schmiermittel kann durch an sich bekannte Einrichtungen, wie beispielsweise eine ölpumpe, zugeführt werden.The invention relates to a screw press for processing plastic plastics, in which the disadvantages mentioned are avoided in that between the serving to absorb the axial pressures Support bearings for the screws and the counter bearing freely rotatable on the screw shafts, preferably separately driven disc-shaped gears are arranged. These gears can be used with any high speeds, for example 1500 revolutions per minute, and thanks to their fast Rotary movement creates an inevitable lubrication between the elements subject to the high axle pressure maintain. The lubricant can by means known per se, such as, for example oil pump, are supplied.
Ein Ausführungsbeispiel einer Schneckenpresse nach der Erfindung ist in der Zeichnung in rein schematischer Form in einem Axialteilschnitt dargestellt. An embodiment of a screw press according to the invention is shown in the drawing in FIG schematic form shown in a partial axial section.
In dem Gehäuse 1 mit Antrittsöffnung 2 sind die Schnecken 3 und 4 zum Kneten und Stauen der
Kunststoffmasse drehbar angeordnet. Sie tragen am rückwärtigen Ende ihrer Wellen fest mit ihnen verbundene
Stützlager 5. Zwischen der als Gegenstützlager dienenden Wandung des Gehäuses 1 und den
Schneckenpresse zum Verarbeiten
von organischen plastischen KunststoffenIn the housing 1 with the opening 2, the screws 3 and 4 are rotatably arranged for kneading and damming the plastic mass. At the rear end of their shafts they have support bearings 5 firmly connected to them. Between the wall of the housing 1, which serves as a counter support bearing, and the screw press for processing
of organic plastic plastics

Stützlagern 5 sind auf den Schneckenwellen frei drehbar Zahnräder 6 angeordnet, die mit hoher Geschwindigkeit umlaufen. Ihre Drehung wird von einem Zahnrad 7 übertragen, das auf einer vorzugsweise von einem besonderen Motor angetriebenen Welle 8 sitzt. Wenn die Schnecken beispielsweise mit 6 bis 30 Umdrehungen in der Minute umlaufen und die Zahnräder 6 eine Umlaufzahl von 1500 in der Minute haben, so ist die relative Geschwindigkeit zwischen den Stützlagern einerseits und den Zahnrädern andererseits 1500 ± (6 bis 30) und 1500—(6 bis 30) Umläufe in der Minute; darauf ergibt sich eine ausreichende Gleichmäßigkeit für die Ölverteilung auf den gegenseitigen Reibungsflächen. Selbstverständlich können zwischen den der Druckaufnahme dienenden Organen auch Rollenstützlager angebracht werden.Support bearings 5 are arranged on the worm shafts freely rotatable gears 6, which operate at high speed circulate. Your rotation is transmitted by a gear 7, which is preferably on a by a special motor driven shaft 8 is seated. For example, if the snails are from 6 to 30 revolutions per minute and the gears 6 a number of revolutions of 1500 per minute have the relative speed between the support bearings on the one hand and the gears on the other hand 1500 ± (6 to 30) and 1500- (6 to 30) revolutions per minute; it results Sufficient uniformity for the oil distribution on the mutual friction surfaces. Of course, roller support bearings can also be used between the organs used for pressure absorption be attached.
Die Erfindung kann bei allen Maschinen dieser Art mit einer oder mehreren Schnecken angewandt werden.The invention can be applied to all machines of this type with one or more screws will.
