Description

Einsatzscheibe für Preßköpfe an Maschinen zur Herstellung plastischer Massen, z. B. Kunsthornmassen, aus Casein oder ähnlichen Stoffen Die bekannten Einsatzscheiben für Preßköpfe an Maschinen zur Herstellung plastischer Massen, z. B. Kunsthornmassen, aus Casein oder ähnlichen Stoffen, bei welchen die Durchgangsöffnungen der Scheiben parallele Wandungen besitzen, haben den Nachteil, daß die nichtgelochten Teile der Scheibe, die sogenannten toten Flächen, den Durchgang der Massen durch den Preßkopf hemmen und daß weiter plötzliche Querschnittsveränderungen vorhanden sind. Um diese Nachteile der toten Flächen zu beseitigen, ist deshalb vorgeschlagen worden, die zwischen den Durchgangsöffnungen befindlichen Rippen der Scheibe keilförmig auszugestalten. Hierdurch wurde jedoch der zweite Nachteil, welcher in der plötzlichen Querschnittsveränderung besteht, nicht behoben.Insert disc for press heads on machines for the production of plastic Masses, e.g. B. artificial horn masses, made of casein or similar materials The known insert discs for press heads on machines for the production of plastic masses, z. B. artificial horn materials, made of casein or similar substances, in which the through openings of the discs have parallel walls, have the disadvantage that the non-perforated parts of the Disc, the so-called dead areas, the passage of the masses through the press head inhibit and that further sudden changes in cross-section are present. Around To eliminate disadvantages of dead areas has therefore been proposed that to design the ribs of the disc located between the passage openings in a wedge shape. However, this became the second disadvantage, which is the sudden change in cross-section exists, not resolved.

Dieser Mangel wird gemäß der Erfindung dadurch beseitigt, daß die Einsatzscheibe derart ausgestaltet ist, daß ihre sich verengenden Durchgangsöffnungen in solche konstanten Querschnittes übergehen.This deficiency is eliminated according to the invention in that the Insert disk is designed such that its narrowing through openings merge into such a constant cross-section.

Die Zeichnung zeigt in den Abb. z und 2 bzw. 3, 4 und 5 zwei Ausführungsbeispiele der Einsatzscheibe gemäß der Erfindung.The drawing shows two exemplary embodiments in FIGS. Z and 2 or 3, 4 and 5 the insert disc according to the invention.

Bei dem Ausführungsbeispiel gemäß der Abb. z sind in das Kopfstück a der Schneckenpresse drei Einsatzscheiben b (Abb. z) eingesetzt. Die Rippen c dieser Scheiben sind in der Richtung gegen das ankommende Material keilförmig ausgestaltet. Die sich derart zunächst verengenden Durchgangsöffnungen gehen dann in solche gleichbleibenden Querschnittes über. Die einzelnen Einsatzscheiben b können unter Umständen vorteilhaft aus zwei übereinanderliegenden Teilscheiben bestehen, von denen die eine sich verengende Durchgangsöffnungen und die andere solche konstanten Querschnittes besitzt.In the embodiment according to Fig. Z are in the head piece a of the screw press, three insert disks b (Fig. z) are inserted. The ribs c of this Slices are wedge-shaped in the direction towards the incoming material. The passage openings that initially narrow in this way then go into those that remain the same Cross-section over. The individual insert disks b can be advantageous under certain circumstances consist of two superimposed partial disks, one of which is narrowing Through openings and the other has such a constant cross section.

Bei dem zweiten Ausführungsbeispiel werden sternförmige Scheiben d gemäß Abb. 4 verwendet, welche zu einer Gruppe gemäß Abb. 5 zusammengesetzt und gemäß Abb.3 in das Kopfstück a der Schneckenpresse eingesetzt sind. Die Sternscheiben d sind hierbei auf einen sich verjüngenden Dorn f mit kegelförmigem Kopf aufgesetzt oder können aus einem einzigen Gruppenstück bestehen.In the second embodiment, star-shaped disks d used according to Fig. 4, which are combined to form a group according to Fig. 5 and are inserted into the head piece a of the screw press as shown in Fig. The star disks d are placed on a tapering mandrel f with a conical head or can consist of a single group piece.
