Description

Tablettenpresse zum Herstellen von Hohl-, insbesondere Ringtabletten aus fas erhaltigen Kunstharzpreßmassen Es sind Tablettenpressen zum Herstellen von Hohl-, insbesondere Ringtabletten aus faserhaltigen und schnitzelförmigen Kunstharzpreßmassen bekannt, bei der die Preßmasse aus einem Füllraum durch einen Vorverdichter seitlich in den Preßraum gedrückt wird, in den ein dem inneren Durchmesser der Hohltablette entsprechender Kern hineinragt.Tablet press for producing hollow tablets, in particular ring tablets from synthetic resin molding compounds containing fiber. There are tablet presses for the production of Hollow tablets, especially ring tablets, made from fiber-containing and chip-shaped synthetic resin molding compounds known, in which the molding compound from a filling space by a pre-compressor laterally is pressed into the compression chamber, in which one the inner diameter of the hollow tablet corresponding core protrudes.

Zum Zweck des gleichmäßigen Verteilens der seitlich in den Preßraum gedrückten PreB-masse um den Kern herum, wurde vo¢geschlagen, den Kern während des Zuführens der Preßmasse in Umdrehung zu versetzen, wodurch die faserhaltige Masse mitgerissen wird. Es wurde auch bereits erwähnt, daß es beispielsweise bei größeren Tabletten von Vorteil ist, daß außer dem Kern auch der Unterstempel an der Umdrehung teilnimmt.For the purpose of evenly distributing the laterally into the baling chamber pressed PreB mass around the core, was vo ¢ hit the core during the To put feeding the molding compound in rotation, whereby the fibrous mass gets carried away. It has also already been mentioned that it is possible, for example, for larger The advantage of tablets is that, in addition to the core, the lower punch is also on the revolution participates.

Dies ist besonders da der Fall, wo es sich um einen -im Verhältnis zum Durchmesser der Tablette kleinen Kern handelt.This is especially the case where there is a -proportionality to the diameter of the tablet is a small core.

Es hat sich nun gezeigt, daß in gewissen Fällen das Verteilen der Preßmasse um den Kern auch schon dadurch erreicht wird, daß lediglich der Unterstempel sich dreht und eine Umdrehung des Kerns nicht unbedingt erforderlich ist. Dies ist besonders da der Fall wo ein faserhaltiges Preßgut verpreßt wird, das sich leicht verfilzt und daher die gesamte Füllung erfaßt. Es werden daher auch die oben in der Form liegenden Teilchen gut um den Kern verteilt. It has now been shown that in certain Cases that Distributing the molding compound around the core is already achieved in that only the lower punch rotates and one rotation of the core is not absolutely necessary is. This is especially the case where a fiber-containing pressed material is pressed, which becomes matted easily and therefore covers the entire filling. So there will be the particles lying on top of the mold are well distributed around the core.

Vorteilhaft wird die Antriebsvorrichtung an der Presse so eingerichtet, daß sowohl nur der Kern, als auch Kern und Unterstempel angetrieben werden können oder nur der Unterstempel, je nachdem es die Größe der zu pressenden Tabletten und die Art der Masse erfordern. The drive device on the press is advantageously set up in such a way that that only the core as well as core and lower punch can be driven or just the lower punch, depending on the size of the tablets to be pressed and the type of crowd require.
