Description
Die Erfindung bezieht sich auf eine Mischmaschine für die Rohstoffe und Zusätze von Weich-und Hart-Schaumkunststoffen. Es können mit einer solchen Mischmaschine die verschiedenen Schaumstoffe aus Kunstharz od. dgl. hergestellt werden, wobei die Rohstoffe in Pulverform oder flüssig in der Maschine verarbeitet werden können. The invention relates to a mixing machine for the raw materials and additives of soft and rigid foam plastics. It can with such a blender the various foams made of synthetic resin od. The like. Are made, wherein the raw materials can be processed in the machine in powder or liquid form.
Die Erfindung besteht darin, daß die Maschine einen Wellenteil mit Nocken erhält, die zwischen mit dem Gehäuse verbundenen Gegennocken umlaufen. Hierbei können die Nocken an einem Verlängerungsstück der Welle und die Gegennocken auf in das auswechselbare Ansatzstück des Gehäuses geschobenen Ringen angebracht sein. Hierbei sind sowohl die Ringe mit den Gegennocken als auch das Verlängerungsstück beliebig austauschbar, und außerdem ist die glatte Welle durch eine Mischwelle ersetzbar. Durch einfache Umstellung lassen sich grob- oder feinporige Schaumstoffe herstellen, wobei das Volumen der Fertigprodukte gleichzeitig in weiten Grenzen beeinflußbar ist. The invention consists in that the machine has a shaft part Receives cams that rotate between counter-cams connected to the housing. Here you can place the cams on an extension piece of the shaft and the counter cams on be attached rings pushed into the interchangeable extension piece of the housing. Here are both the rings with the counter-cams and the extension piece interchangeable as required, and the smooth shaft can also be replaced by a mixing shaft. Coarse or fine-pored foams can be produced by simple conversion, the volume of the finished products can be influenced within wide limits at the same time is.
Die Düsenrohre für den Beschleuniger und zum Einblasen von Luft enden vorteilhaft dicht oberhalb des Verlängerungsstückes. Nach Mischung der Stoffe erfolgt der Ausfluß in bereitgestellte Behälter, in denen alsdann der Schäumungsprozeß beginnt. Die Auslauföffnung der fertigen Mischung ist ebenfalls leicht auswechselbar angeordnet, so daß man die Maschine auch sehr leicht und bequem reinigen kann. The nozzle pipes for the accelerator and for blowing air end advantageously just above the extension piece. After mixing the substances takes place the discharge into prepared containers, in which the foaming process then begins. The outlet opening of the finished mixture is also arranged to be easily exchangeable, so that the machine can also be cleaned very easily and conveniently.
In der Zeichnung ist ein Ausführungsbeispiel einer Mischmaschine gemäß der Erfindung dargestellt, und zwar zeigt Fig. I den Längsschnitt, Fig. 2 den Querschnitt und Fig. 3 die Ansicht der einsetzbaren Mischwelle. In the drawing is an embodiment of a mixing machine shown according to the invention, namely Fig. I shows the longitudinal section, Fig. 2 the cross section and FIG. 3 the view of the insertable mixing shaft.
In dem wassergekühlten Gehäuse I der Maschine läuft die Welle 2 um, über die an ihrem vorderen Ende ein Verlängerungsstück 3 aufgeschoben ist. The shaft 2 rotates in the water-cooled housing I of the machine, over which an extension piece 3 is pushed on at its front end.
Die Welle und das Verlängerungsstück sind gegen Verdrehung zueinander durch einen Keil gesichert.The shaft and the extension piece are against rotation to each other secured by a wedge.
Das Verlängerungsstück 3 trägt an seinem äußeren Umfang die umlaufenden Nocken 4. Über das Verlängerungsstück sind in ein Ansatzstück 14 Ringe j geschoben, die an ihrem inneren Umfang Gegennocken o tragen. Dlie Nocken 4 und 6 bewirken eine innige Mischung der Rohstoffe. Das Düsenrohr 7; durch das der Beschleuniger eingebracht wird, ist durch einen Nocken bis auf das Verlängerungsstück 3, hindurchgeführt. Die Luftzusatzdüse ist ebenfalls durch einen Ring 5 und durch einen Nocken hindurchgeführt. Der Zutritt der Rohstoffe erfolgt durch die Ansätze 10 und I I. Die Austrittsdüse g ist in das Ansatzstück 14 auswechselbar eingeschoben.The extension piece 3 carries the circumferential on its outer circumference Cams 4. 14 rings j are pushed over the extension piece into an extension piece, which have counter-cams o on their inner circumference. Dlie cams 4 and 6 cause one intimate mix of raw materials. The nozzle pipe 7; through which the accelerator is introduced is, is passed through a cam up to the extension piece 3. The additional air nozzle is also passed through a ring 5 and a cam. The raw materials are admitted through batches 10 and I I. The outlet nozzle g is inserted interchangeably into the extension piece 14.
Durch Beimengen von Luft durch die Luftzusatzdüse 8 kann das Fertigprodukt volumenmäßig beeinflußt werden. Auch durch Änderung der Drehzahl der Welle 2 oder der Nocken 4 und 6 läßt sich das Fertigprodukt ändern. By adding air through the additional air nozzle 8, the finished product be influenced in terms of volume. Also by changing the speed of shaft 2 or the cams 4 and 6 can be used to change the finished product.
Die Welle 2 kann auch gegen eine Mischwelle 12 (Fig. 3) ersetzt werden, wodurch die Mischung verstärkt und das Gefüge des Eertigproduktes geändert wird. The shaft 2 can also be replaced by a mixing shaft 12 (Fig. 3), whereby the mixture is strengthened and the structure of the finished product is changed.
