  Misch-und Knetmaschine.



   Die Erfindung betrifft eine   Misch-und      Knetmaschine    mit einem Gehäuse, das innen mit zahnartigen Vorsprüngen ausgerüstet ist und das eine drehbare Schnecke enthält, zwi  schen welcher und    dem Gehäuse eine relative   Hin-und Herbewegung    stattfinden kann, wobei diese   Schneeke    durch radiale Schlitze in eine Anzahl von Schneckenflügeln aufgeteilt ist, zwischen denen im Betrieb der Maschine die erwähnten Zähne des Gehäuses   hindurch-    treten können.



   Bei diesen bekannten   Schneckenmischern    wird im Betrieb aus jedem Schneckengang immer wieder ein Teil des die Schnecke passierenden Gutes durch die Zähne des Gehäuses in den vorangehenden Schneckengang   zurüek-    geführt.   Ifierdurch    wird eine kombinierte   Knet-und Mischwirkung    erzielt, und man kann in vereinfachter Betrachtungsweise sagen, dass jede Massnahme, welche die im wandernden Mischgut entstehenden   Stromungs-    fäden zerreisst, eine Verbesserung der Mischwirkung bringt, während jede Massnahme, durch welche das Mischgut auf seinem Wege erhöhten   Wechseldrucken    ausgesetzt wird und das   Zerquetschen    von Klumpen erfolgt,

   die   Knetwirkung    aber infolge der hiermit verbundenen Erhöhung der innern Reibung auch die Erwärmung des Mischgutes steigert.



   Die Erfindung beruht auf der Erkenntnis, dass man durch passende Ausgestaltung der vom Gehäuse getragenen Zähne und gegebenenfalls auch der die   Durchtrittsspalte    begrenzenden Flanken der Schneckenflügel ohne   merkliehe    Steigerung der ErwÏrmung des Mischgutes die   Mischwirkung    zu steigern vermag. Die   machine    nach der Erfindung kennzeichnet sich dadurch, dass die Frontflächen der Zähne mindestens annähernd senkreeht zur Richtung der Relativbewegung stehen, mit der die Zähne die Spalte zwischen den Sehneekenflügeln passieren.

   Die Zähne schieben dann jeweils einen breiten Haufen des Mischgutes im Spalte vor sich her und führen diesen hierbei jeweils in den vorangehenden Schneckengang   zurüek.    Diese Wir  kung    lässt sich noch erhöhen, wenn man gleiehzeitig die den Spalt begrenzenden Flanken der Schneckenflügel parallel zur Rich  tung    der erwähnten Relativbewegung stellt, so dass die Zähne wie Kolben in einer   Füh-    rung vom einen Schneckengang in den andern hinübergleiten und dabei das Mischgut vor sich   hersehieben.   



   Auf der beiliegenden Zeichnung ist ein Ausfiihrungsbeispiel des Erfindungsgegenstandes veranschaulicht.



   Fig.   1    zeigt einen teilweisen schematischen Längsschnitt und eine teilweise Ansieht einer   : lTisch- und Knetmaschine.   



   Fig. 2 zeigt einen Teil der Abwicklung von Schnecke und Gehäusezähnen in einem   Alantelsehnitt,    der den Eingriff dieser Glieder erkennen lässt.



   Gemäss Fig.   1    läuft die Schnecke 1 mit der Welle 2 innerhalb des Gehäuses 3 in der Richtung des   Drehpfeils      1vl    um und fördert hierbei das Mischgut vom Einlass 4 zum Aus lass   5.    Gleichzeitig wird das Schneckengehäuse 3 durch ein Triebwerk 6 in der   Richtung des Wechselpfeils P2    hin-und   her-    bewegt.



   Die Schnecke 1 ist durch eine Reihe von   Sehlitzen    in eine Anzahl von   Schneeken-    fl geln aufgeteilt,   währenddasGehäuse3    eine entsprechende Anzahl von Zähnen 7 trÏgt, die lÏngs einer Schraubenlinie auf der GehÏuseinnenflÏche verteilt angeordnet und so bemessen sind, dass sie durch die Schlitze zwischen den   Schneekenflügeln      hindureh-    treten können.



   Durch eine synchronisierte Bewegung des Triebwerkes 6 mit der Drehbewegung der Schneckenwelle 2 lϯt sich bei   einer solehen    Anordnung bekanntlich erreichen, da¯ die Zähne 7a,   7 & ...    des Gehäuses 3 auf den aus Fig.   2      erkennbaren'Weglinienzwischenden    Schneckenfl geln 1a, 1b, 1c... hin- und hergeführt   werden.-Sie gehen    hierbei periodisch aus dem Schneckengang I in den Schneckengang II über, um dann in einer Wellenlinie wieder in den Schneckengang I zur ck  zukehren.   



   Wie man nun insbesondere aus Fig. 2 erkennt, sind die   Frontfläehen F    der Zähne 7a, 7b... mindestens annähernd senkrecht zur Richtung der Relativbewegung V gestellt, mit der die Zähne   7a,    7b... die Spalte zwischen den Schneckenflügeln 1a, 1b... passieren.



  Infolgedessen schieben die ZÏhne 7a, 7b... bei ihrem Durchgang durch die erwähnten Spalten das Mischgut in breiter Front vor sich her. Zur Erh¯hung dieser Wirkung werden die den Spalt begrenzenden Flanken der Schneckenfl gel la, l b... vorzugsweise in der dargestellten Art (Fig. 2) so abgeschrägt, dass die parallel zur Richtung V der   genann-    ten Relativbewegung stehen. Sie wirken dann als Führung für das vom Zahn durch den Spalt hindurchgeschobene Mischgut.



  



  Mixing and kneading machine.



   The invention relates to a mixing and kneading machine with a housing which is equipped with tooth-like projections on the inside and which contains a rotatable screw, between which and the housing a relative back and forth movement can take place, this snow turning through radial slots in a number is divided by worm blades, between which the mentioned teeth of the housing can pass when the machine is in operation.



   In these known screw mixers, part of the material passing through the screw from each screw flight is repeatedly returned to the preceding screw flight through the teeth of the housing. As a result, a combined kneading and mixing action is achieved, and in a simplified way it can be said that every measure that breaks the flow threads created in the moving mix brings an improvement in the mixing effect, while every measure that causes the mix on its way is exposed to increased alternating pressures and the crushing of lumps occurs,

   However, the kneading effect also increases the heating of the material to be mixed due to the associated increase in internal friction.



   The invention is based on the knowledge that the mixing effect can be increased without a noticeable increase in the heating of the material to be mixed by suitable design of the teeth carried by the housing and possibly also the flanks of the screw vanes delimiting the passage gaps. The machine according to the invention is characterized in that the front surfaces of the teeth are at least approximately perpendicular to the direction of the relative movement with which the teeth pass the gaps between the tendon wings.

   The teeth then push a wide heap of the mixture in front of them in the gap and lead them back into the previous screw thread. This effect can be increased if at the same time the flanks of the screw vanes delimiting the gap are placed parallel to the direction of the above-mentioned relative movement, so that the teeth slide over in a guide from one screw thread to the other and the material to be mixed in front to kill themselves.



   An exemplary embodiment of the subject matter of the invention is illustrated in the accompanying drawing.



   Fig. 1 shows a partially schematic longitudinal section and a partial view of a table and kneading machine.



   Fig. 2 shows part of the development of the worm and housing teeth in an alantel cut, which shows the engagement of these members.



   According to Fig. 1, the screw 1 with the shaft 2 rotates inside the housing 3 in the direction of the arrow 1vl and conveys the mixture from the inlet 4 to the outlet 5. At the same time, the screw housing 3 is driven by a drive mechanism 6 in the direction of the arrow P2 moved back and forth.



   The worm 1 is divided into a number of snow cap blades by a series of seat strands, while the housing 3 has a corresponding number of teeth 7, which are arranged along a helical line on the inside of the housing and are dimensioned so that they pass through the slots between the snow cap blades being able to step through.



   With such an arrangement, a synchronized movement of the drive mechanism 6 with the rotary movement of the worm shaft 2 can, as is known, achieve that the teeth 7a, 7 & ... of the housing 3 on the path lines between the worm blades 1a that can be seen in FIG , 1b, 1c ... are moved back and forth. -You go periodically from screw flight I into screw flight II, and then return to screw flight I in a wavy line.



   As can now be seen in particular from Fig. 2, the front surfaces F of the teeth 7a, 7b ... are at least approximately perpendicular to the direction of the relative movement V with which the teeth 7a, 7b ... the gaps between the worm blades 1a, 1b ... happen.



  As a result, the teeth 7a, 7b ... push the mix in front of them in front of them as they pass through the gaps mentioned. To increase this effect, the flanks of the screw blades 1 a, 1 b ... which delimit the gap are beveled, preferably in the manner shown (FIG. 2), in such a way that they are parallel to the direction V of the relative movement mentioned. They then act as a guide for the mix pushed through the gap by the tooth.
