Description

Hermann Berstorff Maschinenbau-Anstalt G. m. b. H., Hannover Schneckenpresse für warmformbare Kunststoffe Bei der Behandlung von warmformbaren Kunststoffen in Schneckenpressen hat es sich als wichtig herausgestellt, daß das Kunststoffmaterial entlüftet (ausgedampft) wird.Hermann Berstorff Mechanical Engineering Institution G. m. B. H., Hanover screw press for thermoformable plastics When treating thermoformable plastics in In screw presses it has been found important that the plastic material is vented (evaporated).

Diese Entlüftung findet bis jetzt ungeregelt in der Weise statt, daß die aus dem Kunststoffmaterial austretenden Gase sich entlang dem Schneckengehäuse einen Ausweg ins Freie suchen.This venting takes place so far unregulated in such a way that the gases emerging from the plastic material move along the screw housing looking for a way out into the open.

Bei Schneckenpressen mit zwei ineinandergreifenden kegeligen Schnecken an der Eintrittsstelle des Gutes kann nun gemäß der Neuerung in hochwirksamer Weise eine Entlüftung des Kunststoffmaterials stattfinden, wenn gemäß dem Vorschlage des Gebrauchsmusters die beiden Schnecken etwa lotrecht übereinander angeordnet werden. Die Entlüftung des Materials kann dann durch die oben befindliche Einfüllöffnung stattfinden.In screw presses with two interlocking conical screws at the entry point of the goods can now according to the innovation in a highly effective way a venting of the plastic material take place if according to the proposal of the Utility model the two snails are arranged approximately vertically one above the other. The material can then be vented through the filling opening at the top occur.

Das Entlüften oder Ausdampfen des Materials wird nach einem weiteren Vorschlage des Gebrauchsmusters dadurch begünstigt, daß die Gänge der kegeligen Schnecken auf ihrem Umfang verteilt Schlitze aufweisen. Die Neuerung hat besondere Bedeutung für die Bauart von Schneckenpressen, bei der die Schnecken bzw. die Zylinder beheizt werden.The venting or evaporation of the material is carried out after another Proposals of the utility model favored by the fact that the courses of the tapered Screws have slots distributed around their circumference. The innovation has special features Significance for the design of screw presses, in which the screws or the cylinders be heated.

Auf der Zeichnung ist ein Ausführungsbeispiel des Gebrauchsmustergegenstandes dargestellt, und zwar zeigt Fig. 1 einen Längsmittelschnitt der neuen Schneckenpresse und Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1.In the drawing is an embodiment of the utility model object shown, namely Fig. 1 shows a longitudinal center section of the new screw press and FIG. 2 shows a section along the line II-II in FIG. 1.

An der Eintrittsstelle 1 des Kunststoffmaterials sind zwei kegelige Schnecken 2, 3 angeordnet, die ineinandergreifen und von denen die Schnecke 3 in die Verlängerung 4 übergeht, deren Zylinder 5 in an sich bekannter Weise beheizt wird.At the entry point 1 of the plastic material there are two conical ones Screws 2, 3 arranged, which intermesh and of which the screw 3 in the extension 4 passes over, the cylinder 5 of which is heated in a manner known per se will.

Auch im Bereich der kegeligen Schnecken 2,3 können im Gehäuse der Schneckenpresse Heizkörper 6 angeordnet sein.Also in the area of the tapered screws 2,3 can in the housing of Screw press heater 6 may be arranged.

Wie insbesondere Fig. 2 erkennen läßt, weisen die Gänge der Schnecken 2,3 auf ihrem Umfang verteilt Schlitze 7 auf.As can be seen in particular from FIG. 2, the threads of the screws 2.3 slots 7 distributed on its circumference.

Durch diese wird das Entlüften oder Ausdampfen des Materials weiterhin begünstigt. Schutzansprüche 1. Schneckenpresse für warmformbare Kunststoffe, mit zwei ineinandergreifenden kegeligen Schnecken an der Eintrittsstelle des Gutes, dadurch gekennzeichnet, daß die beiden Schnecken (2,3) etwa lotrecht übereinander angeordnet sind.Through this, the venting or evaporation of the material will continue favored. Protection claims 1. Screw press for thermoformable plastics, with two interlocking conical snails at the point of entry of the goods, characterized in that the two screws (2,3) are approximately perpendicular to one another are arranged.

Claims (1)

2. Schneckenpresse nach Anspruch 1, dadurch gekennzeichnet, daß die Gänge der kegeligen Schnecken (2,3) auf ihrem Umfang verteilt Schlitze (7) aufweisen.2. Screw press according to claim 1, characterized in that the The threads of the conical screws (2, 3) have slots (7) distributed over their circumference.
