My copending application Ser. No. 205,021 filed May 29, 1973 now US Pat. No. 3,735,920 and belonging to the assignee of this application shows several forms of mounting and guiding means for such a stripping knife in which the knife blade is movable to vary its radial spacing from the drum surface, but in which the blade maintains a constant or substantially constant cutting or stripping angle.
SUMMARY OF THE INVENTION The present invention relates to a simpler and more compact support and guide means for a stripping knife.
This object is achieved according to the invention by the fact that a guiding part is provided which, on the one hand, is displaceably guided relatively to the knife support along a first straight line and which, on the other hand, is displaceably guided relatively to the housing along a second straight line, the straight lines having directions. which differ from one another and lying in one plane or each lying in a different plane, the different planes being perpendicular to the axis of the knife carrier.
It is possible in this way for the guiding arrangement for the knife carrier to be of very compact construction.
BRIEF DESCRIPTION OF THE DRAWING The invention is hereinafter explained by way of example and by reference to the drawing, wherein:
FIG. 1 is a longitudinal section through one constructional form of a stripping centrifuge according to the invention, given as an example,
FIG. 2 is a section on an enlarged scale along the line Il-II in FIG. 1 for showing the guide arrangement of the stripping knife,
FIG. 3 is a section along the line IIIIII of FIG. 2,
FIG. 4 is a section similar to FIG. 2 for showing a second example of the guiding arrangement for the strip- I ping knife,
DESCRIPTION OF THE PREFERRED EMBODIMENTS The stripping centrifuge whichis shown in FIG. 1, 2 and 3 comprises a housing 2 which is provided with a housing cover 1 and within which a centrifuge drum 3 is rotatably arranged. Disposed inside the centrifuge 2 drum 3 is a knife carrier 5 which has a stripping knife 6, which extends over the entire internal width of the centrifuge drum 3. The holding part 4 is mounted on the housing 2 and is rotatable about axis 8 (See FIG. 3). This axis 8 extends parallel to the axis 7 of the centrifuge drum.
The carrier shaft 9 of the knife carrier 5 is mounted eccentrically in the holding part 4 and is impositively connected through a connecting part 10 rigidly connected to it to a guiding part 12 which includes first guide means for displacement along a guide rod 11 extending at right-angles to the carrier shaft 9 and in the direction of displacement of the said part 12. The connecting part 10 is in its turn displaceably connected to the guiding part 12 through the second guide means or bush 13 along a straight line 14 extending at rightangles to the carrier shaft 9.
For displacing the guiding part 12 and 'thus the knife carrier 5, the guiding part 12 is connected to a doubleacting servomotor 15, as will be seen from FIG. 1.
'If the guiding part 12 is displaced by means of the servomotor 15 along the guide rod 11, then there is a displacement of the knife carrier 5 parallel thereto, a rotation of the holding part 4 and a displacement of the connecting part 10 in the guide bush 13 of the guiding part 12. In this way, with a displacement of the guiding part 12 and thus of the knife carrier 5, there is no rotation of the carrier shaft 9 in relation to the connecting part 10 and the centrifuge housing 2. Since the holding part 4 has a cylindrical external surface, it can in a simple manner be rotatably mounted in the centrifuge housing and sealed off.
It is also possible for the servomotor 15 to be connected, for example, to the holding part 4 instead of to the guiding part 12. See FIG. 4.
FIG. 4 is a section similar to FIG. 2 also illustrating another example of a constructional form of the guiding arrangement for the stripping knife.
With this stripping knife guide arrangement, the connecting part 10' is connected rigidly to the guiding part 12 and is extended in a displaceable manner through a guide bush 13' connected fast to the carrier shaft 9. The other parts are constructed in the same way as with the constructional example shown in FIG. 1 to 3.
If the carrier shaft 19 is constructed as a hollow sleeve, as shown in FIG. 5, and the knife carrier 5 is connected to a knife shaft 16 which is guided to be axially displaceable but nonrotatable relatively to the hollow shaft, the guide arrangement of the stripping knife can also be used for a stripping knife 6 which is displaceable axially in the drum 3. The servomotor 17 for the displacement of the stripping knife 6 can then be connected, on the one hand, to the knife shaft 16 and,
on the other hand, to the hollow sleeve 19. As in case of the FIG. I embodiment the servomotor may be connected to the rotary holding part 4 rather than to the sleeve 19.
With the constructional form according to FIG. 6,
I claim:
