Description
Die Erfindung bezieht sich auf eine Misch- und Knetmaschine für Gummi und ähnliche plastische Massen, bei der in einem Gehäuse Kneter umlaufen. Die Erfindung besteht darin, daß der Boden des Gehäuses als Klappe ausgebildet ist, die mit Hilfe eines von der Kolbenstange eines oszillierenden Zylinders gesteuerten Gestänges vollkommen geöffnet und dicht geschlossen wird.The invention relates to a mixing and kneading machine for rubber and the like plastic masses in one case Circulate the kneader. The invention consists in that the bottom of the housing as a flap is formed by means of one of the piston rod of an oscillating cylinder controlled linkage is fully opened and tightly closed.
Die Bodenklappe ist ferner mit einer Sperrvorrichtung versehen, die ebenfalls durch die Kolbenstange des oszillierenden Zylinders in die Verschlußlage gebracht wird.The bottom flap is also provided with a locking device, which is also through the The piston rod of the oscillating cylinder is brought into the closed position.
Hierdurch wird erreicht, daß nicht allein der Boden des Knetgehäuses während der Be-Schickung schnell und sicher abgedeckt, sondern auch ein Austreten des Rohmaterials trotz des bedeutenden Gegendruckes verhindert wird. Die Dichthaltung der Klappe während des Kneten» wird dabei dadurch be-This ensures that not only the bottom of the kneading housing during loading covered quickly and safely, but also prevents the raw material from escaping despite the significant counter pressure will. The tightness of the flap during kneading »is thereby reduced.
wirkt, daß der im Innern des Gehäuses herrschende hohe Druck durch einen gleich hohen Druck auf der Gegenseite ausgeglichen wird. Dies geschieht dadurch, daß der Verschluß ebenso wie die Öffnung durch den Kolben desselben oszillierenden Zylinders hervorgebraciht wird, so zwar, daß beim Rückwärtsgang des Kolbens die Öffnung der Bodenklappe durch ein besonderes Gestänge erfolgt, während ίο beim Vorgang des Kolbens der Verschluß der Bodenklappe durch das Gestänge in der Totpunktlage des letzteren hervorgebracht wird. Das letztere Moment ist deshalb wichtig, weil dadurch an Betriebskraft während des Verschlusses' der Bodenklappe gespart j wird. !acts that the prevailing inside the housing high pressure by an equally high Pressure on the opposite side is balanced. This is done by the closure as well as the opening through the piston of the same oscillating cylinder is, so that when the piston is in reverse, the opening of the bottom flap through a special linkage takes place, while ίο the closure during the operation of the piston the bottom flap brought about by the linkage in the dead center position of the latter will. The latter moment is important because it gives rise to operating power during the closure 'of the bottom flap is saved j. !

Das Gehäuse 4 der Misch- und Knet- ; maschine ist mit einer Bodenöffnung 5 versehen, welche durch eine Klappe 6 geschlossen werden kann, die von der im Maschinenrahmen gelagerten Welle 7 getragen wird1. Um die Klappe drehen zu können, ist sie mit einem vorspringenden Arm 8 versehen, welcher am freien Ende gelenkig mit einer Kolbenstange 9 eines Kolbens 11 verbunden ist, da er in einem oszillierenden Zylinder 10 auf und ab bewegt wird. Der Zylinder 10 besitzt in seinem Bodendeekel ein Schwinglager 12, um welches er pendeln kann. Wird in den Zylinder 10 Dampf, Wasser oder Druckluft oberhalb des Kolbens 11 eingelassen, so wird mittels des Kolbens 11 und der Kolbenstange 9 der Arm 8 der Klappe 6 .derart bewegt, daß die Klappe die öffnung 5 schließt. Wird dagegen unterhalb des Kolbens 11 das Druckmittel eingeführt, so wird dadurch die Klappe in die in Abb. 2 in punktierten Linien angegebene Stellung bewegt, also geöffnet. Die Zuführung des Druckmittels zum Zylinder 10 kann in beliebiger Weise gesteuert werden.The housing 4 of the mixing and kneading; The machine is provided with a bottom opening 5 which can be closed by a flap 6 carried by the shaft 7 mounted in the machine frame 1 . In order to be able to rotate the flap, it is provided with a projecting arm 8 which is articulated at the free end to a piston rod 9 of a piston 11, since it is moved up and down in an oscillating cylinder 10. The cylinder 10 has a swing bearing 12 in its bottom cover, around which it can swing. If steam, water or compressed air is let into the cylinder 10 above the piston 11, the arm 8 of the flap 6 is moved by means of the piston 11 and the piston rod 9 in such a way that the flap closes the opening 5. If, on the other hand, the pressure medium is introduced below the piston 11, the flap is thereby moved into the position indicated in dotted lines in FIG. 2, that is to say opened. The supply of the pressure medium to the cylinder 10 can be controlled in any way.
Die Klappe wird in der Verschluß lage durch einen Ansatz 13 gehalten, welcher, wenn er mit der Rolle 14 in Eingriff gelangt ist, von dieser gestützt wird; die Rolle ist zu diesem Zweck in den oberen Enden der Arme 15 angebracht, die mit der Welle 16, welche im Maschinenrahmen gelagert ist, fest verbunden sind. Die Welle 16 ist mit einer Stange 17 versehen, weiche zur Freigabe der Klappe entsprechend bewegt werden muß. Das äußerste Ende der Stange 17 steht durch eine Gelenkstange 18 mit der Kolbenstange 19 in Verbindung. Die Kolbenstange 19 wird in ähnlicher Weise wie -die Kolbenstange 9 durch einen im Zylinder 21 beweglichen. Kolben 20 angetrieben. Soll die Klappe geöffnet werden, so wird das Druckmittel auf die entsprechende Kolbenseite des Kolbens 20 im Zylinder 21 zur Einwirkung gebracht, wodurch die Stange 17 die in punktierten Linien (Abb. i) angegebene1 Lage annimmt. Hierdurch wird die Welle 16 ebenfalls zum Ausschwingen gebracht und bewegt ihrerseits die Rolle 14, so daß letztere außer Eingriff mit dem Ansatz 13 der Klappe 6 tritt. Sobald die Klappe 6 durch den Kolben 11 wieder geschlossen ist, wird die Welle 16 durch den Kolben 20 zurückbewegt, so daß alsdann die Rolle 14 mit dem Ansatz 13 wieder in Eingriff tritt.The flap is held in the closure position by a projection 13 which, when it has come into engagement with the roller 14, is supported by this; For this purpose, the roller is mounted in the upper ends of the arms 15, which are firmly connected to the shaft 16, which is mounted in the machine frame. The shaft 16 is provided with a rod 17 which must be moved accordingly to release the flap. The outermost end of the rod 17 is connected to the piston rod 19 by a toggle rod 18. The piston rod 19 is in a similar manner to the piston rod 9 by a movable in the cylinder 21. Piston 20 driven. If the flap is to be opened, the pressure medium is brought into action on the corresponding piston side of the piston 20 in the cylinder 21, whereby the rod 17 assumes the 1 position indicated in dotted lines (Fig. I). This also causes the shaft 16 to oscillate and in turn moves the roller 14 so that the latter disengages from the projection 13 of the flap 6. As soon as the flap 6 is closed again by the piston 11, the shaft 16 is moved back by the piston 20, so that the roller 14 then comes into engagement with the projection 13 again.
Anstatt getrennte Zylinder zum Verschluß und zum Öffnen der Klappe zu benutzen, kann die Klappe mit der Grundplatte 22, wie Abb. 3 zeigt, mittels zweier Gelenkglieder 23, 24 verbunden sein. Eines dieser Glieder, beispielsweise 24, ist mit der Kolbenstange 25 des Kolbens 26 des Zylinders 27 gelenkig verbanden, 'der ebenfalls, jedoch in horizontaler Lage, schwingen kann. Sobald die Klappe bei dieser Anordnung geschlossen ist, liegen die Gelenkglieder 23 und 24 in einer geraden Linie, so daß dadurch eine Totpunktlage samtlicher Drehzapfen eintritt, und die Klappe in der Verschlußstellung gehalten wird.Instead of using separate cylinders for closing and opening the flap, the flap with the base plate 22, as shown in Fig. 3, by means of two joint members 23, 24 be connected. One of these links, for example 24, is connected to the piston rod 25 of the piston 26 of the cylinder 27 articulated, 'which is also, but in a horizontal Able to swing. As soon as the flap is closed in this arrangement, lie the joint members 23 and 24 in a straight line, so that thereby a dead center position more all Pivot enters, and the flap is held in the closed position.
Wird der Kolben in entgegengesetzter Richtung bewegt, so nehmen die Gelenkglieder 23, 24 die in Abb. 3 in punktierten Linien angegebene Stellung ein, so daß die Klappe 6 geöffnet wird.If the piston is moved in the opposite direction, the joint links take off 23, 24 the position indicated in Fig. 3 in dotted lines, so that the flap 6 is opened.
