Description
Schleifstein für Holzschleifer zur Herstellung- von Holzschliff. Es ist bei Holzschleifsteinen bekannt, die Schleiffläche des Steines mit einfachen Nuten zu durchfurchen oder sich kreuzende erhabene Schneiden mit aneinandergereihtenVertiefungen anzuwenden, in die sich die durch das Schleifen losgelösten langen Fasern einlegen können. Auf derartige Schleifsteine bezieht sich die Erfindung. Nach ihr wird der Schleifstein mit sich kreuzenden Nuten derart durchfurcht, daß die Schleiffläche in abgestumpfte erhabene Zähne von verhältnismäßig kleinem Grundriß zerlegt ist. Dadurch soll bei gleichem Kraftverbrauch gegenüber den bekannten Steinen die Nutzleistung erheblich gesteigert werden. Außerdem soll durch die verhältnismäßig nahe beieinander liegenden, in verschiedenen Richtungen verlaufenden Nuten der lange Faserstoff sicher aufgenommen werden, auch wenn er sich in verschiedenen Richtungen liegend löst, wodurch seine weitere Zerkleinerung unter der nächsten Presse mit Sicherheit verhütet wird.Grinding stone for wood grinders for the production of wood pulp. It is known for wood grindstones, the grinding surface of the stone with simple Grooves to be furrowed or intersecting raised cutting edges with recesses lined up into which the long fibers, loosened by the grinding, are inserted can. The invention relates to such grinding stones. After her the Grooved grindstone with intersecting grooves in such a way that the grinding surface is broken down into truncated raised teeth of a relatively small plan. As a result, the useful power should be achieved with the same power consumption compared to the known stones can be increased considerably. It also aims to be relatively close to each other lying grooves running in different directions secure the long fiber material be picked up, even if it loosens lying in different directions, whereby its further crushing under the next press will be prevented with certainty will.
In der Zeichnung sind mehrere Ausführungen der Erfindung schematisch dargestellt. Die Schleiffläche des Schleifsteines a (Abb. x) ist nach der Erfindung mit sich schneidenden Nuten b (vgl. auch die Abb. 2, 3 und q.) derart durchfurcht, daß Zähne c entstehen (Abb. 5). Dabei ist es gleichgültig, ob die Nuten b geradlinig oder gekrümmt (Abb. q.) verlaufen und in welchem Winkel sie sich schneiden.Several embodiments of the invention are shown schematically in the drawing shown. The grinding surface of the grindstone a (Fig. X) is according to the invention furrowed with intersecting grooves b (see also Figs. 2, 3 and q.) in such a way that that teeth c arise (Fig. 5). It does not matter whether the grooves b are straight or curved (Fig. q.) and at what angle they intersect.
In Abb. 2 ist ein Teil einer abgewickelten Schleiffläche dargestellt, in der die Nuten b geneigt zur Schleifsteinachse derart verlaufen, daß Zähne c von quadratischem oder annähernd q#1^dr,iticchem Grundriß entstehen. Bei der A-Icuilung der Schleiffläche durch Nuten bi gemäß Abb. 3 sind Zähne cl von dreieckigem Grundriß gebildet, während in Abb. q. gekrümmte Nuten b2 dargestellt sind.In Fig. 2 a part of a developed grinding surface is shown, in which the grooves b are inclined to the grindstone axis in such a way that teeth c of square or approximately q # 1 ^ dr, iticchem ground plan. At the A-Icuilung the grinding surface through grooves bi according to Fig. 3 are teeth cl of a triangular plan formed, while in Fig.q. curved grooves b2 are shown.
Zweckmäßig ist es, wie aus Abb. x zu ersehen ist, den Querschnitt der Nuten b, bi, b2 so zu wählen, daß in der Drehrichtung des Steines a (Pfeil x) die Nutenkanten d den Scheitelpunkt eines stumpfen Winkels bilden. Dadurch wird ein Schneiden der Kanten d verhütet.It is useful, as can be seen from Fig. X , to choose the cross-section of the grooves b, bi, b2 so that the groove edges d form the apex of an obtuse angle in the direction of rotation of the stone a (arrow x). This prevents the edges d from being cut.
In Abb. 5 ist vergrößert ein einzelner Schleifzahn c gezeichnet, der erkennen läßt, daß die Zahnkanten in der Schleifrichtung stumpf sind.In Fig. 5, a single grinding tooth c is drawn enlarged, the shows that the tooth edges are blunt in the grinding direction.
