Description
Bei den verschiedenen Systemen von Schneidmühlen, die zum Körnen von Kunststoffabfällen dienen, welche in Injektionspressen eingeführt werden sollen, sind die Messer fest angebracht, und zwar einerseits auf einem festen Statox und andererseits auf einem Rotor. Bei jedem Nachschleifen müssen diese Messer auf ihrem Befestigungshalter neu eingestellt werden, damit die Schneidkanten der festen Messer des Stators genau mit den Schneidkanten der Messer des Rotors fluchten.In the various systems of granulators used for granulating plastic waste serve, which are to be introduced into injection presses, the knives are firmly attached, namely on the one hand on a fixed Statox and on the other hand on a rotor. Every time you have to regrind these knives can be readjusted on their mounting bracket so that the cutting edges are fixed The blades of the stator are exactly aligned with the cutting edges of the blades of the rotor.
Diese Arbeit erfordert eine große Genauigkeit, und das endgültige Festklemmen der Befestigungsschrauben der verschiedenen Messer geschieht nach einer Reihe aufeinanderfolgender Einstellungsproben, bis die genaue Lage für jedes dieser Messer festgelegt istDaraus ergibt sich ein großer Zeitverlust für diese Einstellongen. Andererseits besteht die Gefahr, daß eine frühzeitige Lockerung der Befestigungsschrauben infolge der dauernden Stöße beim Schneiden ein gewaltsames Anhalten durch Aufeinanderprallen der zwei Messer und infolgedessen mehr oder weniger schwere mechanische Schäden hervorruft.This work requires great accuracy and the final tightening of the fastening screws of the various knives happens after a series of successive adjustment tests until the exact position for each of these knives is determined, resulting in a great loss of time for these settings. On the other hand, there is a risk of premature loosening of the fastening screws as a result of the constant jolts when cutting, a violent stop due to impact which causes two knives and consequently more or less severe mechanical damage.
Aus diesem Grunde sind gewisse Brecher mit Sicherheitsvorrichtungen versehen, wie Brechstiften zwischen der Antriebsscheibe und der Welle des Rotors. Hierdurch werden jedoch die beschriebenen grundsätzlichen Nachteile nicht vermieden.For this reason, certain crushers are provided with safety devices, such as break pins between the drive pulley and the shaft of the rotor. This, however, eliminates the described fundamental disadvantages not avoided.
Es sind zwar schon Einsteilvorrichtungen bei Holzbearbeitungsmaschinen u. dgl. bekannt, die zum Einstellen der einzelnen Messer dienen, jedoch erfolgte hierbei die Einstellung über Exzenterscheiben od. dgl., so daß sie nicht für den robusten Betrieb in Schneidmühlen verwendbar sind.There are already adjustment devices in woodworking machines and the like. Known for Adjustment of the individual knives are used, but here the adjustment was made using eccentric disks or the like, so that they cannot be used for robust operation in cutting mills.
Die Erfindung betrifft eine Schneidmühle mit am Rotor und am Stator angeordneten, auf einem gedachten Zylindermantel zusammenarbeitenden Messern.. Das Neue besteht darin, daß an beiden Enden des Rotors auf dem gedachten Zylindermantel liegende Anschläge vorgesehen sind, gegen sie sich die Rotormesser mit den Enden ihrer Schneidkanten von innen anlegen, und daß an den Stirnwänden des Statorgehäuses ebenfalls auf dem gedachten Zylindermantel liegende Anschläge vorgesehen sind, gegen die sich die Statormesser mit den Enden ihrer Schneidkanten von außen anlegen, wobei die Statormesser in ihrer Schneidkante Ausschnitte für die am Rotor vorgesehenen Anschläge aufweisen.The invention relates to a cutting mill with arranged on the rotor and on the stator, on an imaginary Cylinder jacket cooperating knives .. The new thing is that at both ends of the rotor are provided on the imaginary cylinder jacket lying stops, against them the rotor blades with the ends of their cutting edges from the inside, and that on the end walls of the stator housing Also on the imaginary cylinder jacket are provided stops against which the Place the stator knives with the ends of their cutting edges from the outside, with the stator knives in their Have cutting edge cutouts for the stops provided on the rotor.
Dadurch werden alle oben beschriebenen Nachteile beseitigt. Wegen der automatischen Einstellung aller Klingen bei der Lagerung gegen feste Anschläge, die genau auf die Achse zentriert sind, kann in keinem Falle eine Verschiebung der einzelnen Messer über den Flugkreis hinaus stattfinden, und es ist somit einThis eliminates all of the disadvantages described above. Because of the automatic hiring of everyone Blades when stored against fixed stops that are exactly centered on the axis cannot be used in any If there is a shift of the individual knives beyond the flight circle take place, and it is thus a

Die Erfinduing wird in einem Ausführtmgsbeispiel an Hand der Zeichnungen näher erläutert. In der Zeichnung stellt darThe invention is explained in more detail in an exemplary embodiment with reference to the drawings. In the Drawing represents
Abb. 1 den Aufriß einer Schneidmühle gemäß der Erfindung,Fig. 1 is an elevation of a cutting mill according to the invention,
Abb. 2 einen Teilschnitt nach der Linie II-II der Abb. 1,Fig. 2 is a partial section along the line II-II of Fig. 1,
Abb. 3 ein Rotormesser der erfindungsgemäßen Schneidmühle.Fig. 3 shows a rotor knife of the cutting mill according to the invention.
Der Stator 1 trägt die Lager, in denen die zum Rotor 4 gehörige Welle 3 eingezapft ist.The stator 1 carries the bearings in which the shaft 3 belonging to the rotor 4 is journaled.
Jedes der Messer 5 des Stators liegt in einer Lagerung 6, die Schuibschrauben 7 und Fesitstellschrauben 8 trägt, während jedes Messer 9 des Rotors durch Schrauben 10 verschoben und durch Schrauben 11 festgezogen werden kann.Each of the knives 5 of the stator lies in a bearing 6, which carries shear screws 7 and fastening screws 8 , while each knife 9 of the rotor can be displaced by screws 10 and tightened by screws 11.
Gemäß der Erfindung besitzen die beiden Flansche des Stators 1 jeder einen kreisförmig fortlaufenden \Torsprung 12 oder mehrere auf dem gleichen Kreis angeordnete Einzelvorsprünge 25. Der Kreis ist der Flugkreis der Messer. Er liegt konzentrisch zur Welle 3. Der Rotor 4 ist an seinen Seitenwandungen mit je einer Scheibe 13 versehen, deren Rand 14 nach dem Inneren der Vorrichtung zu umgebogen ist. Der äußere Durchmesser der Scheibe ist etwas größer als der Flugkreis, während die Innenkante des Randes ebenfalls auf dem Flugkreis liegt.According to the invention the two flanges of the stator 1 have each orsprung a circularly continuous \ T 12 or more are arranged on the same circle individual projections 25. The circle is the circle of the blades. It is concentric to the shaft 3. The rotor 4 is provided on each of its side walls with a disk 13 , the edge 14 of which is bent towards the interior of the device. The outer diameter of the disc is slightly larger than the flight circle, while the inner edge of the rim is also on the flight circle.
