Description
Vorrichtung zur Herstellung von stranggepreßten Kunststofferzeugnissen mit mehrfarbigen Oberflächeneffekten Die Erfindung betrifft eine Vorrichtung zur Herstellung von stranggepreßten Kunststofferzeugnissen mit mehrfarbigen Oberflächeneffekten. Device for the production of extruded plastic products with multicolored surface effects The invention relates to a device for Manufacture of extruded plastic products with multicolored surface effects.
Es sind bereits Vorrichtungen bekannt, die Kunststoffkörper, wie Profile od. dgl., mit marmorlertem 'oder maseriertem Aussehen herzustellen gestatten. There are already devices known, the plastic body, such as Profiles od. The like. Allow to manufacture with marbled 'or grained appearance.
Diese bekannten Vorrichtungen bestehen aus Strangpressen, die zur Erzielung der mehrfarbigen Effekte in dem Zuführungskanal einen rotierenden Zylinder aufweisen, der im Zylindermantel mit Bohrungen versehen ist. In Höhe dieser Bohrungen befinden sich bei diesen bekannten Vorrichtungen senkrecht zur Zylinderachse angeordnete Zuführungskanäle, durch die andersfarbige Kunststoffmassen dem rotierenden Zylinder zugeführt werden, der diese in der zu verarbeitenden Masse verteilt. These known devices consist of extrusions that are used for A rotating cylinder is used to achieve the multicolored effects in the feed channel have, which is provided with holes in the cylinder jacket. At the level of these holes are in these known devices arranged perpendicular to the cylinder axis Feed channels through which the different colored plastic masses the rotating cylinder are supplied, which distributes them in the mass to be processed.
Diese bekannten Vorrichtungen mit rotierenden Zylindern weisen jedoch einen komplizierten Aufbau auf und sind dementsprechend auch nur zu verhältnismäßig hohen Gestehungspreisen herstellbar. However, these known devices with rotating cylinders have have a complicated structure and are therefore only too proportionate high cost prices.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine wirtschaftliche Vorrichtung einfacher Bauart zur Herstellung von stranggepreßten Kunststofformkörpern mit mehrfarbigen Oberflächeneffekten zu schaffen. The invention is accordingly based on the object of an economical Device of simple design for the production of extruded plastic moldings to create with multicolored surface effects.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß in dem Zuführungskanal einer an sich bekannten Strangpresse od. dgl. eine oder gegebenenfalls auch mehrere drehbar gelagerte Hohlwellen im rechten Winkel zur Strömungsrichtung angeordnet sind, die mit Zuführungsvorrichtungen, wie z. B. This object is achieved according to the invention in that in the Feed channel of an extrusion press known per se or the like or optionally also several rotatably mounted hollow shafts at right angles to the direction of flow are arranged with feeding devices such. B.
Schneckenpressen, verbunden sind. Die Hohlwellen weisen dabei erfindungsgemäß eine Vielzahl von Bohrungen auf, durch die andersfarbige Massen, insbesondere Kunststoffmassen, dem Zuführungskanal der Strangpresse od. dgl. zugeführt und der darin fließenden Kunststoffmasse beigemischt werden. Screw presses, are connected. According to the invention, the hollow shafts have a large number of holes through which different colored compounds, especially plastic compounds, the feed channel of the extruder od. Like. Supplied and the flowing therein Plastic compound are added.
Die Anzahl der Bohrungen in den Hohlwellen sowie die Form der Bohrungen und deren Anordnung können in weitem Maße variieren. Sie richten sich nach dem jeweils erstrebten Oberflächeneffekt der herzustellenden Erzeugnisse. Gegebenenfalls können diese Bohrungen auch mit erhöhten Austrittsröhrchen versehen sein. The number of holes in the hollow shafts and the shape of the holes and their arrangement can vary widely. They depend on each desired surface effect of the products to be manufactured. If necessary, can these holes can also be provided with raised outlet tubes.
Um die Erzielung der vielfältigsten Oberflächeneffekte zu ermöglichen, sieht die Erfindung weiter Vorrichtungen, wie z. B. Regler, vor, welche die Drehzahl der Hohlwellen und die Zuflußgeschwindigkeit des andersfarbigen Materials zu variieren gestatten. Der Zufluß kann dabei gemäß der Erfindung schubweise oder kontinuierlich erfolgen. In order to enable the achievement of the most diverse surface effects, the invention further provides devices such. B. controller, before which the speed to vary the hollow shafts and the inflow speed of the different colored material allow. According to the invention, the inflow can be intermittent or continuous take place.
Mit Hilfe der erfindungsgemäßen Vorrichtung lassen sich beliebige Kunststofformkörper, z. B. Profile, Platten oder Folien mit den verschiedensten zwei-oder mehrfarbigen Oberflächeneffekten, wie Marmorierung oder Maserierung, erhalten. With the help of the device according to the invention can be any Plastic moldings, e.g. B. Profiles, plates or foils with the most diverse Two or more colored surface effects, such as marbling or grain, are obtained.
Die Erfindung ist an Hand der in der Abbildung schematisch dargestellten Ausführungsform näher erläutert. The invention is shown schematically on the basis of the figure Embodiment explained in more detail.
Die Materialzuführung erfolgt bei der dargestellten Ausführungsform in an sich bekannter Weise durch einen Extruder. Der als rechteckiger Querschnitt ausgebildete Zuführungskanal 1 ist im rechten Winkel von einer drehbar gelagerten Hohlwelle 2 unterbrochen, die mit einer Vielzahl von Bohrungen für das andersfarbige Material versehen ist. Die Bohrungen weisen Austrittsröhrchen 3 auf. Der Zufluß des andersfarbigen Materials erfolgt in der üblichen Weise mittels einer zweiten Schneckenpresse in das Zentrum der Hohlwelle 2 über einen Verbindungskanal 4. Zum Antrieb der Hohlwelle 2 dient das Antriebsorgan5, das der Hohlwelle eine beliebig variierbare Drehbewegung erteilt. The material is supplied in the embodiment shown in a manner known per se by an extruder. The one as a rectangular cross-section trained supply channel 1 is at right angles from a rotatably mounted Hollow shaft 2 interrupted, with a large number of holes for the different colored Material is provided. The bores have outlet tubes 3. The tributary the different colored material is done in the usual way by means of a second Screw press in the center of the hollow shaft 2 via a connecting channel 4. To The hollow shaft 2 is driven by the drive element 5, which the hollow shaft has any variable rotary movement granted.
Durch die Hohlwelle 2 können einfarbige Materialien oder inhomogene Mischungen von zwei- oder mehreren verschiedenfarbigen Materialien zugeführt werden, wodurch die Erzielung von zwei- oder mehrfarbigen Effekten unter Verwendung einer einzigen Hohlwelle ermöglicht wird. Selbstverständlich kann ein mehrfarbiger Effekt auch dadurch erzielt werden, daß man zwei oder mehrere Hohlwellen anordnet, die jeweils ein andersfarbiges Material zuführen. Through the hollow shaft 2, single-colored materials or inhomogeneous Mixtures of two or more different colored materials are supplied, making it possible to achieve two or more colored effects using a single hollow shaft is made possible. Of course, a multicolored effect can be used can also be achieved by arranging two or more hollow shafts that feed a different colored material each time.
