Derartige Schneidmühlen sind unter dem Gesichtspunkt des Umweltschutzes äußerst bedenklich, da sie laut sind und zum Betrieb einen hohen Energiebedarf erfordern; auch ist insbesondere bei der Zerkleinerung von Schaumstoff eine hohe Staubentwicklung festzustellen. Derartiger Staub kann nicht verarbeitet werden, sondern muß als nichtverwertbarer Abfall behandelt werden und belastet somit die Mülldeponien. Such cutting mills are from the point of view of Environmental protection extremely questionable, since they are loud and for Operation require high energy consumption; is too a high level especially when shredding foam Detect dust formation. Such dust cannot processed, but must be as non-recyclable waste are treated and thus pollutes the landfills.
Zur Vermeidung dieser Nachteile wird nach der Erfindung vorgeschlagen, an der rotierenden Halterung ein umlaufendes Messerband zu lagern. Nach einer vorteilhaften Ausgestaltung der Erfindung weist die Halterung einen Antrieb auf.To avoid these disadvantages it is proposed according to the invention on the rotating holder to store a rotating knife band. According to an advantageous embodiment of the invention, the Bracket a drive.
Vorteilhaft an dieser Vorrichtung ist, daß hiermit, im Gegensatz zu der Schneidmühle gemäß der US-PS 27 39 647, Kunststoffteile vorbestimmter Länge hergestellt werden können. Bei der bekannten Schneidmühle werden die Kunststoffteile mit zunehmendem Verschleiß der Klingen mehr abgerissen als abgeschnitten. Hierbei wird, insbesondere bei der Zerkleinerung von Schaumstoff, dieser in die Länge gezogen, so daß die Größe der Schaumstoffteile nicht mehr vorherbestimmbar ist.The advantage of this device is that hereby, in Contrary to the cutting mill according to US Pat. No. 2,739,647, Plastic parts of a predetermined length are produced can. In the known granulator, the Plastic parts with increasing wear of the blades torn off as cut off. Here, especially at the shredding of foam, this in length pulled so that the size of the foam parts no longer can be predetermined.
Im einzelnen besteht die rotierende Halterung aus einer in einem Rahmen drehbar gelagerten Welle, die zwei drehbare Achsen zur Aufnahme des Messerbandes aufweist, wobei mindestens eine dieser Achsen einen Antrieb besitzt. Auf den Achsen ist hierbei jeweils ein Rad zur Führung und Aufnahme des Messerbandes angeordnet. In vorteilhafter Weise ist der Abstand zwischen den beiden Achsen veränderbar, wodurch das Einspannen des Messerbandes bzw. das Nachspannen ermöglicht wird.In particular, the rotating holder consists of an in a frame rotatable shaft, the two rotatable Has axes for receiving the knife belt, wherein at least one of these axes has a drive. On the Axes are each a wheel for guidance and reception of the knife belt arranged. Advantageously, the Distance between the two axes can be changed, which means that Clamping the knife band or re-tensioning allows becomes.
Nach einem weiteren vorteilhaften Merkmal der Erfindung ist das Messerband beidseitig angeschliffen, so daß durch das Messerband der Schaumstoff bei einer Drehung von jeweils 180 Grad geschnitten wird. According to a further advantageous feature of the invention the knife band grinded on both sides, so that by the Knife tape the foam with a turn of 180 Degree is cut.
Hierdurch erhöht sich die Standzeit des Messerbandes bzw. es wird der Durchsatz an zerkleinertem Kunststoff erhöht.This increases the service life of the knife belt or it the throughput of shredded plastic is increased.
Gegenstand der Erfindung ist ebenfalls eine Einrichtung zur Erzeugung von Teilchen aus Kunststoff, insbesondere aus geschäumtem Kunststoff, mit mindestens einer, vorzugsweise zwei einander gegenüberliegend angeordneten rotierenden Wellen mit Kreismessern und mit einem nachgeordneten Transportband, wobei dem Transportband das Werkzeug zum Zerkleinern von Kunststoffteilen mit einer Trennorgane tragenden Halterung nachgeordnet ist, bei dem an der rotierenden Halterung ein umlaufendes Messerband gelagert ist.The invention also relates to a device for Production of particles from plastic, in particular from foamed plastic, with at least one, preferably two rotating ones arranged opposite each other Waves with circular knives and with a subordinate Conveyor belt, the conveyor belt the tool for Shredding plastic parts with a separator supporting bracket is subordinate, in which at the rotating holder a revolving knife band is mounted.
Die Erfindung wird nachfolgend durch eine in der Zeichnung dargestellte beispielsweise Ausführungsform erläutert.The invention is illustrated by an example embodiment shown in the drawing explained.
Die Zeichnung zeigt die gesamte Vorrichtung in einer Draufsicht. Die Vorrichtung selbst besteht aus einem insgesamt mit 1 bezeichneten Rahmen, der eine Schneideinrichtung 2 aufweist, die aus zwei einander gegenüberliegend angeordneten rotierenden Wellen 3, 4 besteht, die jeweils mit mehreren parallel zueinander angeordneten Kreismessern 5, 6 versehen sind. Mit Hilfe dieser Schneideinrichtung werden beispielsweise in Richtung des Pfeiles X eingeführte Kunststoffplatten zu Streifen zerschnitten. Diese Streifen werden von dem dieser Schneideinrichtung 2 nachgeordneten Transportband 7 aufgenommen und dem Werkzeug 8 zum weiteren Zerkleinern zugeführt. The drawing shows the entire device in a plan view. The device itself consists of a frame, generally designated 1 , which has a cutting device 2 , which consists of two rotating shafts 3, 4 arranged opposite one another, each of which is provided with a plurality of circular knives 5, 6 arranged parallel to one another.
