Description

Die Erfindung betrifft Schneckenpressen für Tonwaren u. dgl. mit Schlitzvorlage und durch -,eine in den Pressenzylinder hineinragende Düse gebildeter Entlüftungsvorrichtung. Bei Schneckenpressen dieserArt wird fürden Regeffall Sicherheit dagegen geschaffen, daß in die Mündung der Entlüftungsvorrichtung Ton gelangt und dadurch die Wirkung des Vakuums verringert. lAlenn in der Presse zunächst festes und anschließend weiches Material verarbeitet wird, kann es aber vorkommen, daß die durch die Düse gebildete Entlüftungsvorrichtung sich verstopft. In diesem Fall muß Jie Düse gereinigt werden. Aufgabe der Erfindung ist es, eine einfache, betriebssichere Vorrichtung zu schaffen, die das Reinigen der Düse ohne Unterbrechung des Pressenbetriebes ermöglicht.The invention relates to screw presses for pottery and the like with a slot template and a venting device formed by a nozzle protruding into the press cylinder. With screw presses of this type, security is created against that sound gets into the mouth of the venting device and thereby the effect the vacuum is reduced. lAlenn in the press first firm and then soft Material is processed, but it can happen that the formed by the nozzle Ventilation device clogged. In this case, the nozzle must be cleaned. The object of the invention is to create a simple, reliable device, which enables the nozzle to be cleaned without interrupting the press operation.

Diese Aufgabe wirderfindungsgemäß,dadurch gelöst, daß die Presse mit einem während, des Betriebes in die Düse eingeführten Stößel ausgerüstet ist.This object is achieved according to the invention in that the press with a plunger inserted into the nozzle during operation.

Der Stößel wird vorzugsweise durch einen stabförrnigen Körper gebildet, der im wesentlichen die Öffnung der Düse ausfüllt. Dieser Stößel kann z. B. schwenkbar mit einer Welle sein. d.ie aus dem Pressengehäuse nach außen iherausgeführt und hier mit einem Hebel verbunden ist. Der Stößel kann auch geradlinig bewegt werden, und man kann einen selbsttätigen, masehineflen Betrieb des, Stößels vorsehen.The plunger is preferably formed by a rod-shaped body, which essentially fills the opening of the nozzle. This plunger can, for. B. pivotable be with a wave. d.they are taken out of the press housing to the outside and connected here with a lever. The ram can also be moved in a straight line, and one can provide for an automatic, self-contained operation of the ram.

In der Zeichnung ist ein Ausführungsbeispieldes Erfindungsgegenstandes in Fig. i im senkrechten Mittelschnitt und in Fig. 2 im Querschnitt nach der Linie 11-11 der Fig. i dargestellt. Im Preßzylinder 3 mit -der Beschickungsöffnung 4 laufen die Preßschnecken 5 und 6 um, zwischen denen sich dde Schlitzvorlage 7 befindet. Beim Austritt aus Ader Schlitzvorlage 7 wird der Ton einem Unterdruck unterworfen durch die in den Preßzylinder hineinragende, Düse 8, die in tangentialer Richtung zur Schneckenwefle 9 mündet. Die Dreihrichtung der Schnecke. 6 ist durch, den Pfeil io angegeben; der von der Schnecke in der Umfangsrichtung mitgenommene, in der Nähe der Düse 8 befindliche Ton entfernt sich demnach von der Düsenmündung 8a.In the drawing, an exemplary embodiment of the subject matter of the invention is shown in FIG. 1 in a vertical central section and in FIG. 2 in a cross section along the line 11-11 of FIG. In the press cylinder 3 with the feed opening 4, the press screws 5 and 6 run around, between which the slot template 7 is located. When it emerges from the vein slot template 7 , the clay is subjected to a negative pressure through the nozzle 8 which protrudes into the press cylinder and opens out in the tangential direction to the screw shaft 9 . The direction of rotation of the snail. 6 is indicated by the arrow io; the clay carried along by the screw in the circumferential direction and located in the vicinity of the nozzle 8 accordingly moves away from the nozzle mouth 8a.

,Zur Reinigung der Düse dient der Stößel i i, der mittels des Hebels 12 auf der Welle IS befestigt ist, .die im Pressengehäuse gelagert und aus diesem ,nach außen, herausgeführt ist. Die Welle 13 kann durch den Handhebel 14 hin undher bewegt werden, so daß der Stößel i i in die Düse 8 eingeführt und ,die Düse dadurch gereinigt werden kann.To clean the nozzle, the plunger ii is used, which is attached to the shaft IS by means of the lever 12, which is mounted in the press housing and led out of this to the outside. The shaft 13 can be moved back and forth by the hand lever 14 so that the plunger ii can be inserted into the nozzle 8 and the nozzle can be cleaned thereby.

Wer-den mehrere Düsen in der Umfangsrichtung angeordnet, so wird man zweckmäßig jede Düs«2 mit einem Stößel versehen-; diese Stößel können gemeinsam betätigt werden.If several nozzles are arranged in the circumferential direction, one becomes it is expedient to provide each nozzle 2 with a plunger; these plungers can be shared be operated.
