Abstract

The scrap film is automatically sucked out of the container, torn up and the scraps conveyed to a vertical worm feed which plasticizes the film without additional heating. The plastic mass is then filtered clean before passing directly to a blow head or a strand granulator.

Description

2. Bei Aufgabe von Folienschnitzel wird zusätzlich eine Zerreißmaschine benötigt und die Aufgabe der Schnitzel kann auch nicht ohne Bedienungsperson erfolgen.2. A tearing machine is also used when feeding shredded film required and the task of the schnitzel cannot be done without an operator.

3. Nach dem heutigen Stand der Technik steht die Leistung dieser Maschinen in keinem Verhältnis zum Aufwand.3. The performance of these machines is based on the current state of the art in no relation to the effort.

Aufgabenstellung Der Folienindustrie eine kontinuierlicharbeitende Maschine zur Verfügung zu stellen, die bei allen Arbeitsgängen mit einem maximalen Nutzefekt arbeitet.Task The film industry is a continuously operating one To make the machine available for all operations with a maximum Beneficial works.

1. Folienabfälle aus einem Vorbehälter selbst ansaugt.1. Sucks in foil waste from a pre-container itself.

2. Die Folien zerreißt.2. The foil tears.

3. Die Folienschnitzel einer vertikal angeordneten Schnecke zuführt, die so ausgelegt ist, daß sie ohne Zusatzheizung die Schnitzel plastifiziert.3. Feeds the shredded film to a vertically arranged screw, which is designed so that it plasticizes the chips without additional heating.

4. Die plastische Masse durch schnell auswechselbare Siebe drückt und somit reinigt.4. The plastic mass pushes through quickly exchangeable sieves and thus cleanses.

5. An dieses Regenerierungsaggregat kann unmittelbar ein Folienblaskopf, oder ein Stranggranulator angeschlossen werden.5. A film die head can be attached directly to this regeneration unit, or a strand pelletizer can be connected.

Beschreibung der neuentwickelten Maschine In Anlage 1 Zeichnung Die Folien werden in dem Vorbehälter Pos. 1 aufgegeben und vom Rotor Pos. 3 angesaugt. Durch die Schrägstellung der Rotorflügel wird die Folie nach unten geschleudert und an den Standmessern Pos. 4 zerrissen. Die Ansaugluft entweicht nach oben und prallt gegen das Abweisblech Pos. 2.Description of the newly developed machine in Appendix 1 drawing Die Foils are placed in the pre-container pos. 1 and sucked in by the rotor pos. 3. Due to the inclined position of the rotor blades, the film is thrown downwards and torn at the stand knives item 4. The intake air escapes upwards and hits the deflector plate pos. 2.

Bei dem Zerreißvorgang wird bereits Wärme erzeugt. Diese vorgewärmten Schnitzel werden von den Schneckenwindungen Pos. 5 aufgenoflen, plastifiziert und zum Schnellsiebwechaler Pos. 6 befördert. Pos. 9 sind Gegendruckwindungen. Pos. 8 Antrieb, Umdrehungen 2000 U/min.During the tearing process, heat is already generated. These preheated Schnitzel are taken up by the screw windings pos. 5, plasticized and promoted to the quick-change screen pos. 6. Pos. 9 are counter pressure turns. Item 8 drive, revolutions 2000 rpm.

Stand der Technik Verfahren Nr. 1 Zur Zeit sind Folien- Zerreißmaschinen bekannt und in der Industrie eingesetzt, mit denen im Chargenbetrieb Regenerat- Granulat hergestellt wird.Background Art Method No. 1 At present, there are film tearing machines known and used in industry, with which in batch operation regenerated Granulate is produced. Kritik des Standes der Technik an Verfahren Nr. 1 1. Die Maschinen arbeiten im Chargenbetrieb unrationell.Prior art criticism of method no. 1 1. The machines work in batch operations inefficiently. 2. Das gewonnene Granulat ist nicht von Verschmutzung und Fremdkörpern gereinigt, muß also über eine Strangpresse und einem Stranggranulator weiterverarbeitet werden.2. The granules obtained are free from dirt and foreign bodies cleaned, so it has to be processed further in an extruder and a strand granulator will. Stand der Technik Verfahren Nr. 2 Folien, oder Folienschnitzel werden in horizontalliegende Extruderschnecken kontinuierlich aufgegeben und durch Zylinderheizung plastifiziert. Durch Siebeinlagen wird die plastische Masse gereinigt.State of the art Method No. 2 films, or film shreds Continuously fed into horizontal extruder screws and through cylinder heating plasticized. The plastic mass is cleaned by sieve inserts. Kritik des Standes der Technik an Verfahren Nr. 2 1. Bei der Aufgabe von unzerrissenen Folien muß eine Bedienungsperson ständig die Folien der Schnecke aufgeben.Prior art criticism of method no. 2 1. At the task An operator must constantly remove the foils from the screw when the foils are not torn to give up.
