Abstract

An arrangement for extruding plastic, comprises a filling section (1) for charging the extruder with the material to be plastified. The filling section has at least one opening (2). The opening is square or round, and is located at the end (3) of the filling section. The opening is arranged radially to the filling section, and can be closed using a stopper. The inner contour (4) of the filling section is matched to the stopper. The opening is used for servicing, cleansing and/or carrying out inspections.

Description

  • Die Erfindung betrifft eine Vorrichtung zum Extrudieren von plastischen Massen, die mindestens ein Füllteil zur Bestückung des Extruders mit der zu plastifizierenden Masse umfasst. The invention relates to an apparatus for extruding plastic masses, comprising at least one filling member for the assembly of the extruder with the mass to be plasticized.
  • Vorrichtungen zum Extrudieren von plastischen Massen, bei denen eine Möglichkeit der Materialeinbringung geschaffen ist, sind im Stand der Technik bekannt. Apparatuses for extruding plastic masses, in which a possibility of the introduction material is provided, are known in the art. So beschreibt beispielsweise die Thus, for example, the DE 298 18 525 U1 DE 298 18 525 U1 einen Planetwalzenextruder, bei dem ein Einspritzring zwischen zwei Walzenteilen zur Eingabe von Material, wie Flüssigkeit, vorgesehen ist. a planetary roller extruder, in which an injector ring between two roller parts for the input of material, such as liquid, is provided. Derartige Ringe werden auch zwischen einem Füllteil und einem Walzenteil eingesetzt. Such rings are also used between a filling and a roller part.
  • Über diese Ringe kann nur eine begrenzte Menge Material zugegeben werden. About this rings a limited amount of material can be added.
  • Aufgabe der Erfindung ist es, eine Vorrichtung anzubieten, mit der größere Mengen an Material als Zusatzstoffe der zu plastifizierenden Masse beigegeben werden kann. The object of the invention is to provide a device which can be added as additives to the plasticized mass with the larger amounts of material.
  • Die Aufgabe wird in Verbindung mit dem Oberbegriff des Anspruches 1 dadurch gelöst, dass mindestens eine Öffnung im Füllteil angeordnet ist. The object is achieved in connection with the preamble of claim 1, characterized in that at least one opening in the filling member is arranged. Die Öffnung kann eckig oder rund ausgeführt sein. The opening can be designed rectangular or round. Vorteil- hafterweise ist die Öffnung am Ende des Füllteils angeordnet, sinnvollerweise also direkt hinter dem Flansch des Füllteiles. Advantageous adhesive enough, the opening is arranged at the end of the filling, thus usefully directly behind the flange of the infill member.
  • Sind mehrere Öffnungen angeordnet, werden diese bevorzugt symmetrisch zueinander um das Füllteil angebracht. If a plurality of openings are arranged, these are preferably symmetrical to each other are attached to the filling. Die Öffnung sollte möglichst großvolumig sein, damit auch eine ausreichende Menge Material beigefügt werden kann. The opening should be as large a volume as possible, so that a sufficient amount of material can be attached.
  • Die Öffnungen sind radial zum Füllteil angeordnet und so ausgeführt, dass sie mittels eines Stopfens verschlossen werden können, wobei der Stopfen so ausgeführt ist, dass er der Innenkontur des Füllteils angepasst ist. The openings are arranged radially to the filling section and designed so that they can be closed by a plug, the plug being designed such that it is adapted to the inner contour of the filling. Dies hat den Vorteil, dass sich kein Material im Inneren des Zylinders absetzen kann. This has the advantage that no material inside the cylinder can settle. Wenn erforderlich kann der Stopfen ebenso wie das Füllteil mit einer Temperierung ausgestattet sein, damit die Temperatur geregelt und/oder gesteuert werden kann. If required, the plug may be equipped with a temperature control as well as the filling, so that the temperature is regulated and / or can be controlled.
  • Über die Öffnung sind mittels einer Fördereinrichtung, vorzugsweise eines Extruders oder einer Pumpe, Zusatzstoffe einbringbar. Via the opening are connected by means of a conveying device, preferably an extruder or a pump, additives can be introduced. Als Zusatzstoffe können Gase, Flüssigkeiten und Schmelze in den Prozess eingebracht werden. As additives, gas, liquid or melt can be introduced into the process.
  • Weiterbildungsgemäß ist vorgesehen, über die Öffnung Material abzusaugen und/oder zu entnehmen. According to one development, it is provided to suck material about the opening and / or remove.
  • Die Öffnung kann aber auch so ausgeführt werden, dass sie als Wartungs-/Reinigungs- und/oder Inspektionsöffnung zu verwenden ist. but the opening can also be designed so that they should be used as a maintenance / cleaning and / or inspection opening.
  • Die vorgeschlagene Vorrichtung eignet sich besonders beim Einsatz in einem Planetwalzenextruder. The proposed device is particularly suitable for use in a planetary roller extruder.
