ii e 3 c h r e 1 b u n gii e 3 c h r e 1 b u n g
Ulatt - 3 -Figur 1 zeigt im schnitt das synchron laufende, ineinander greifende Messerwalzenpaar ( 1 ).Ulatt - 3 - Figure 1 shows in section the synchronously running, one within the other gripping knife roller pair (1).
Jede der !esserwalzen ist mit einem Mantel umhiillt, vorzugsweise aus Stahlblech, bei welchem die dem Durchlass zugewandte Seite so aufgeschlitzt ist, daß zwischen dem Aussendurchmesser der Walze und den jeweiligen Schlitzenden ein geringer spalt verbleibt. Dadurch wird verhindert daß ichnittgutreste in das Innere der Ummantelung transportiert werden. Gleichzeitig ergeben die-Stahlblechmäntel zusammengesetzt einen Teil des Ein - und Auslaßschachtes. ( 2 Die Abstreiferlamelle ( 3 ),ein gestanztes Stahlblechteil wird einmal auf dem Kerndurchmesser der Walze zentriert und ist spiegelgleich so geschlitzt, daß die nden der Ummantelung beidseitig in die Abstreiferlamelle hineinragen und ein Verdrehen derselben ausschließen. Die jeweils gegenüberliegenden Abstreiferlamellen ergeben gleichzeitig eine Verengung des Ein-bzw. Quslaßschachtes, sodaß den Sicherheitsbestmmungen entsprechend, ein Berühren der Messerwalzen und evtl. Verletzungen ausgeschlossen sind.Each of the knife rolls is covered with a jacket, preferably made of sheet steel with the side facing the passage slit open is that between the outer diameter of the roller and the respective slot ends a small gap remains. This prevents cut material residues from getting into the Be transported inside the jacket. At the same time, the sheet steel jackets result assembled part of the inlet and outlet shaft. (2 The wiper blade (3), a stamped sheet steel part is once on the core diameter of the roller centered and is slit mirror-like so that the ends of the casing are on both sides protrude into the wiper blade and prevent it from twisting. the Opposite scraper lamellae simultaneously result in a constriction of the one or. Exhaust shaft, so that the safety regulations in accordance with Touching the knife rollers and possible injuries are excluded.
Figur - 2 -zeigt im Prinzip den gleichen Aufbau der einzelnen Elemente mit runder Ummantelung.Figure 2 shows in principle the same structure of the individual elements with round sheathing.
Figur -3-zeigt im Prinzip den gleichen Aufbau der einzelnen Elemente mit beidseitig offenem Stahlmantel.Figure -3 shows in principle the same structure of the individual elements with steel jacket open on both sides.
Blatt -4-Figur -4-zeigt das Zentrierblech (4 @, welches beide Enden des Stahlmatels fixiert.Sheet -4-Figure -4-shows the centering plate (4 @, which both ends of the steel frame fixed.
Das Zentrierblech wird durch die Bundbuchsen, in welchen die esserwalzen gelagert sind, positioniert ( 5 ), Dadurch wird ein stets gleichbleibendes Abstandsverhältnis zwischen messerwalze und ummantelung gewährleistet. binde Verdrehung oder Verschiebung ist ausgeschlossen.The centering plate is through the flange bushings, in which the esserwalzen are stored, positioned (5), This ensures a constant distance ratio guaranteed between knife roller and casing. bind twist or displacement is excluded.
Figur (5) zeigt in der Draufsicht in Teilschnitt noch einmal ien gesamten Aufbau der einzelnen Elemente : (1) = !esserwal7en (2) = Ummantelung (3) = Abstreiferlamelle (4) = Zentrierblech (5) = Bundbuchse (6) = Lagerplatine Blatt -5-Figur - 6 -zeigt im Seitenschnitt die Position des Gesamten Schneidwerkes im Gehäuse : (7) = Gehäuse - Oberteil (8) = Gehäuse - Unterteil durch die völlig dicht ummantelten iesserwalzen einmaß und durch die Weichgummidichtungen ( 10 ) zwischen Gehäuse und Schneidwerk wird eine Staubentwicklun- innerhalb des Gehäuses absolut sicher verhindert.Figure (5) shows in a plan view in partial section again ien entire Structure of the individual elements: (1) =! Esserwal7en (2) = casing (3) = scraper lamella (4) = centering plate (5) = flange bushing (6) = bearing plate sheet -5-figure - 6 -shows in the side section the position of the entire cutting unit in the housing: (7) = housing - Upper part (8) = housing - lower part through the completely tightly encased esser rollers one dimension and through the soft rubber seals (10) between the housing and cutting unit the development of dust inside the housing is absolutely reliably prevented.
Ein sehr wesentlicher Vorteil der hier zusammengefügten Abstreiferelemente legt darin, daß mit einem einzigen Stanzteil ( tbstreiferlamelle ) durch individuelle zusammenlegen ( 2-Stück / 3-Stück / 4-Stück) alle Schnittbreiten erzielt werden können, je nach Bedarf.A very important advantage of the wiper elements assembled here lays in that with a single stamped part (tbstreiferlamelle) by individual combine (2-piece / 3-piece / 4-piece) all cutting widths can be achieved can, as needed.
