Description

Vorrichtung zum Zerstören der Struktur des Preßstranges in Strangpressen Es sind Vorrichtungen bekanntgeworden, die dazu dienen sollen., Strukturen im Massestrang vor dem Austreten aus dem Mundstück -der Strangpresse zu zerstören. Es sind dazu Messer, die schneckenförmig neben-und übereinander angeordnet sind, verwandt worden, zwischen denen sich der Strang durchquetschen Lind auch: die Drehung der Messer bewirken sollte. Der Durchgang des Materials an dieser Stelle zeigte einen verengten; Querschnitt des Zylinders.Device for destroying the structure of the extruded strand in extrusion presses Devices have become known which are intended to serve., Structures in the ground strand to be destroyed before exiting the die of the extruder. There are to Knives that are arranged next to and above one another in a helical shape have been used, between which the rope squeezes and also: the rotation of the knife should effect. The passage of the material at this point showed a narrowed; Cross section of the cylinder.

Ferner ist eine Vorrichtung bekannt, wo bei, gleichem freien Querschnitt wie beim Zylinder Schneckenmesser übereinander angeordnet sind, die in gleicher Richtung umlaufen.Furthermore, a device is known where, with the same free cross section As with the cylinder worm knives are arranged one above the other, which in the same Circulate direction.

Zweck der vorliegenden Erfindung ist .es, die Übelstände der vorstehend erwähnten Vorrichtungen auszumerzen, da sie ihren Zweck nicht -erfüllen. Zu diesem Zweck erhält der zwischen Preßzyl,inder und Preßkopfeingeschaltete Apparat zwei übereinanderliegznde, sich berührende Förderschnekken, die den Durchgangsquerschnitt nicht verengen, aber in entgegengesetzter Richtung umlaufen und dadurch die Struktur des, Stranges verschieben und zerstören. Diese Arbeit wird noch weiter dadurch unterstützt, daß die jeweils der Drehrichtung entsprechenden außen; sitzenden Schneckengänge in entgegengesetzter Richtung arbeiten, um zu verneid.en, daß sich das Material an den Seiten des Schneckengehäuses anhäuft. Hierdurch wird die Wirkung des Strukturzerstörers noch erhöht. .The purpose of the present invention is to remedy the shortcomings of the above to stamp out the devices mentioned, as they do not serve their purpose. To this The purpose of the apparatus, which is switched between the press cylinder, the inder and the press head, is twofold Superposed, touching screw conveyors that form the passage cross-section do not narrow, but go around in the opposite direction and thereby the structure des, move and destroy strand. This work is further supported by that the outside corresponding to the direction of rotation; sedentary snail ducts work in the opposite direction to avoid letting the material move accumulates on the sides of the screw housing. This will destroy the structure still increased. .

Auf der Zeichnung ist der Erfindungsgegenstand meinem Ausführungsbeispiel dargestellt, und zwar zeigt Abb. i den Apparat im Aufriß, Abb. a im Querscaumtt.In the drawing, the subject of the invention is my embodiment shown, namely Fig. i shows the apparatus in elevation, Fig. a in a cross-section.

Anschließend an den Zylinder der Strangpresse a i;st das Gußstück b mit Deckel c und d angebracht. Die beiden Wellen e und f -tragen. die Schneckenböden g, die sich in entgegengesetzter Richtung drehen. Der Antrieb erfolgt durch konische Räder 1v und i oder auch durch Schneckenrad und Schnecke von der Welle der Einzugwalze h der Strangpresse aus mittels Kettentrieb 1. Schneckenböden m und iz erhalten entgegengesetzte Steigung. Die Übertragung von der angetriebenen: Welle auf die getriebene Welle erfolgt durch Kuppelräder o. An dem Apparat wird der Preßkopf >> in der bekannten Weise angeschlossen. Then the casting b with cover c and d is attached to the cylinder of the extruder ai; st. The two waves e and f - wear. the screw bottoms g, which rotate in the opposite direction. It is driven by conical wheels 1v and i or also by a worm wheel and worm from the shaft of the feed roll h of the extrusion press by means of a chain drive 1. Screw bottoms m and iz have opposite inclinations. The transmission from the driven shaft to the driven shaft takes place through coupling wheels o. The press head >> is connected to the apparatus in the known manner.

PATENTANSPRUCH: Vorrichtung zum Zerstören der Struktur des Preßstranges in Strangpressen mit Hilfe zweier im Pressenrumpf vor dem Pressenmundstück übereinander gelagerter Förderschnecken; dadurch gekennzeichnet, daß die beiden Förderschnecken das Preßgut in .entgegengesetzter Richtung befördern, wobei die Endschneckengänge (n bzw. m) jeder Förderschnecke eine zum übrigen Teil der zugehörigen Förderschnecke entgegengesetzte Förderrichtung aufweisen, um das Anhäufen des. Preßgutes an den Seiten des Schneckengehäuses zu verhüten und die Strukturzerstörung noch zu ;erhöhen.PATENT CLAIM: Device for destroying the structure of the extruded strand in extrusion presses with the aid of two screw conveyors placed one above the other in the press body in front of the press mouthpiece; characterized in that the two screw conveyors convey the material to be pressed in opposite directions, the end screw threads (n and m) of each screw conveyor having a conveying direction opposite to the remaining part of the associated screw conveyor in order to prevent the material to be pressed from piling up on the sides of the screw housing and the structural destruction will increase.
