Brief description of the pelletizing machine
FIG. 1 is a partial plan view of a matrix disc with a pressing rolling, of a rotary pelletizing machine in accordance with the present invention;
FIG. 2 is a partial section of the rotary extruder machine in accordance with the present invention;
FIG. 3 is a view showing a pressing roller with a drive of the inventive pelletizing machine, in a working position; and
FIG. 4 is a view showing a pressing roller with its drive in a disassembled position.
A rotary pelletizing machine in accordance with the present twin screw extruder has a rotatable matrix disc which is identified with reference numeral 2. The matrix disc 2 is provided with a plurality of matrix openings uniformly distributed over its periphery. Pellets are pressed in the matrix opening 4 of the matrix disc .
As shown in FIGS. 3 and 4, the pressing roller is held in a bearing block 18. The bearing block is provided with a linear guide which is vertically adjustable on a column.
A partial radial adjustment is advantageous when the matrix disc 2 together with the upper plungers and the lower plungers 12 must be turned out of the single screw extruder for their cleaning or their exchange.
A complete separation of the pressing roller with its bearing block and its linear guide from the drive housing is performed when the pressing rollers with their bearings must be worked for example for the purpose of maintenance.
A height adjustable spindle for adjusting of the pressing roller 6 is also a component of the drive in the housing. The adjustment is performed by a worm wheel which cooperates with a worm. The adjustment can be performed manually or mechanically.
A plurality of cable connections for measurement and control of a device are not shown in the drawings. They are connected to the housing 28 through an end switch.
Without further analysis, the foregoing will so fully reveal the gist of the present pelletizing machine that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
