Claims. (Cl. 107-14) My invention'relates to pellet mills or the like, and moreparticularly to an adjustment indicator for the compression means in such' mill, such compression means usually being in the form of one or more compression rollers.-
- The inventionis particularly applicable to mills of thetype described in'Meakin patent for E):- trusion: Mill, No. 2,336,114, of December '7, 1943, whercinthe compression means is a roller supported on a hingedly mounted door spanning a horizontally disposed compression chamber.
- In cleaning out. the-compression chamber in such mill or in effecting repairs or replacements therein, an initial lifting of the roller from-thedie essential to permit: such roller to swing clear of the die, as the door is opened. Consequently, not only is. it desirable, in such acaseyto have some positiveindicationthat the roller is'sufficiently" removed from contact with the die to permit clearance upon opening of such door, but, in replacing the roller, it is desirable to be able to quickly and accurately reestablish the roller adjustment previously existing between. the roller and the'die.
The invention, in its preferred form, has been depicted-in a millof the type disclosed in the aforementioned patent but utilizing a pair of compression rollers-,and for a detailed description of such preferred formof the invention, reference will be had to the accompanying drawings where-- I Figure 1- 15a fragmentary front clevational view of such mill embo'dyi-ngmy invention;
- Figurez isa fragmentary side elevationalview in section through the pertinent portion of the mill of. Fi e 1.; r
Figure 3: is a view'partly in. section, through thejadiusting' and indicating mechanism of the; present'i-nvention'; 1 Figure 4 is a; front elevational View of the adjusting and indicating. mechanism of the present invention; I 1
Figure 5 is a view in section, through thesmechanism. of Figure 4;.
The; particular mill illustrated comprises a: housing .5: ha i ga; front. wall 1' and a: parallel disposed:partition-wall 9 determininga section of the housing within which the: extrusion---functionof-themillwtakes place. The die H is preferably of cylindrical shape, clamped to'a backing disk [3 forming one en'd wall of. the compression chamber. Clamping'of the die to the disk is effected by a plurality of clamping elements l5 di'stributedabout the periphery of the disk and die, each of such elements being bolted tothe" V 2 edge" of the backing disk and engaging in a pcripheral edge groove in said disk and a corresponding groove around the die.
The backing disk is preferably integrally united to one end of the die shaft H which extends through the partition wall for drive connection to a suitable power source such as an electric motor (not shown). Thus the die is adapted for rotation in the operation of the specific mill under consideration.
The front Wall of the housing is provided with an opening therethrough concentric with and of greater diameter than the'entrance to the. compression chamber formed by the cylindrical die and the backing disk. Such opening is adapted to be closed by a door [9 hinged to the front Wall of the housing, the door being provided with a circular insert 21 facing the free edge of the cylindrical die and having a plurality of circular grooves on its exposed surface. The door is thus adapted to function as a closure for the compression chamber and constitute the front end wall thereof when in its closed position.
A screw feed assembly 22 affixed to the door is adapted to feedthrough the door and into the compression chamber, material to be compressed and extruded through the die.
The door is formed with a pair of spaced bosses 23 each having a longitudinal passage therethrough for a stub shaft 25 which extends into the compression chamber and provides a support on Whichto'mount a compression roller 25. That portion 21 of each such shafts, which lies within the chamber; has its axis eccentric to the axis of the stub shaft proper. Such eccentric relationship permits of adjustment of the roller with respect to the inner or compression surface of the die, through partial'rotation of the stub shaft, and the location of the bosses in which the stub shafts are mounted, is such as to permit of such. adjustment of each roller from a position in spaced relationship with respect to the die, to a position in compression contact with the surface of the die. In this manner, Wear on the part of the roller. or die may be compensated for. I Such. adjustment is made possible by squaring off the outer end 29 of the stub shaft and mounting thereon a gear 31 which is held thereon by a lock nut 32'. The gear is enclosed by an open-faced shroud 33 which provides spaced bearings in its side walls 35, 31 for a worm 39 which is held in mesh with the gear. At one end of the Worm shaft there is mounted a hand-operated. adjusting wheel'4'l to permit of manual rotation of the worm to effect adjustments of the associated roller.
The shroud at its open end, is closed by a plate 45 having an opening 46 therein exposing the lock nut end of the stub shaft together with an arcuate portion of the gear lying adjacent the stub shaft.
With a roller adjusted to its maximum spaced relationship with respect to the compression surface of the die, a marker 41 is applied to the gear adjacent one end of the exposed arcuate portion thereof. Such marker may be in the form of a nut 49 bolted to the gear and carrying on its fac an indicia in the form of an arrow 5|. A corresponding indicia or arrow 53 is applied to the plate 45 in registry with the arrow 5|, at a point on the edge formed by the opening through theplate.
An indicia such as an arrow 54 on the exposed end of each stub shaft and correspondin in direction with that on the gear marker, will facilitate the proper orientation of a gear when assembled on the shaft.
Any manipulation of the adjusting mechanism from the position representing maximum spaced relationship between the roller and the die surface will bring the roller closer to the die until a desired pressure contact with the compression surface of the die is established. Such adjusting movement of the roller will be represented on the indicator by movement of the marker along an arcuate path coinciding with the exposed arcuate portion of the gear. The extent of such arcuate path of travel will vary, of course, with wear of the roller and of the die.
Prior to opening of the door to the compression chamber, the rollers must be backed off from their pressure contact with the surface of the die, and accordingly the handwheel associated with each roller control mechanism will be rotated until the arrow on the marker is brought back to a position of registry with the arrow on the plate, thus indicating maximum spacing of the roller with respect to the die,
In restoring the mill to operation, it is desirable, if the same rollers are used, to be able to quickly and accurately restore such rollers back to their previous pressure contact relationships with respect to the die, and this is made possible by adding to each plate, a scale 55 along the edge bordering the arcuate path of travel of the marker. With such scale available, the adjustment of the roller associated with that particular control mechanism may be noted prior to destroying such adjustment in preparation for opening of the door to the compression chamber. Thereafter, following the replacement of such rollers, the previous adjustment of the rollers may be then restored, quickly and accurately, by restoring the marker back to the position on the scale which it occupied just previously.
The lock nut 32 may be relied on to preclude any undesirable tampering with the adjusting mechanism. Consequently, when an adjustment is to be made, such lock nut must first be loosened to free the adjusting mechanism for operation.
The indicator of the present invention thus performs two very desirable functions in connection with adjusting of the rollers within the compression chamber. First, it enables an operator to quickly, and with assurance, ascertain the maximum spacing of the rollers with respect to the die in preparation for removal of such rollers from the compression chamber; and secondly, where the same rollers are to be returned to the compression chamber, the indicator enables them to be quickly and accurately restored to the same pressure contact relationship which existed just prior to their removal from the compression chamber.
It will thus be apparent that the invention as described above in its preferred form, fulfills all the objects of the present invention. While the invention has been illustrated and described in its preferred form and in connection with a particular type of pellet mill, the same is applicable to other types of mills and is subject to alteration and modification without departing from the underlying principles thereof; and I, accordingly, do not desire to be limited in my protection to the specific details illustrated and described, except as may be necessitated by the appended claims.
