Problems solved by technology

Here too, a time-dependent variation in the coefficient of friction is caused, since the lubricant (mostly oil) hardens more or less after a while and thus produces a relatively high starting torque, which prevents the normally desired Small axial friction requirements
In addition to this, the sleeve support mechanism entails certain costs

Embodiment Construction

[0014] The device has a cylindrical granulation housing 1 which is closed at its one end by a perforated plate 2 . An inlet channel 3 is provided in the orifice plate for the plasticized material to be granulated, especially thermoplastics, which flows in the direction of the arrow 4 from the inlet channel 3 into a plurality of distribution channels 5, which On the end side 6 of the perforated plate 2 , the channels open into nozzles 7 which are arranged on a circle and at equal distances around the central longitudinal axis 8 of the granulation housing 1 . This axis 8 simultaneously forms the axis of rotation of a shaft 9 which carries a cutter head 10 at its end facing the orifice plate 2, which is equipped with a plurality of knives 11 which, when the shaft 9 rotates, rotate in the direction indicated by arrows 12. in the direction of ( image 3 ) over the orifice of the nozzle 7 and thus breaks the plastic mass extruded from the nozzle 7 into small particles. The shaft 9...

Abstract

The invention relates to a device for granulation of an ejected material from at least one nozzle (7), in particular a thermoplastic plastic, with a perforated plate (2) comprising the nozzles (7). A blade head (10) supporting several blades (11) lies opposite the same, fixed to a shaft (9) which is rotatably driven by a motor (13). The motor (13) is suspended such as to be displaced relative to the housing (1) by means of a suspension (15), however the above is suspended in such a manner that displacement is only possible in the direction of the axis (8) of the shaft (9) and not in a radial direction. The suspension (15) comprises at least one membrane (14) which suspends the motor (13) on the granulator housing (1). The motor (13) can be adjusted relative to the perforated plate (2) by means of an adjuster device (27), such that the desired pressure of the blade on the perforated plate (2) is maintained. The excised granulate particles are drawn out of the housing (1) by means of coolant.

Description

technical field [0001] The invention relates to a device for granulating material extruded from at least one nozzle, especially thermoplastics, which has an orifice with a nozzle, opposite to which there is at least one knife cutter heads fixed on a shaft driven by a motor for rotational movement and adjustable in the axial direction so that each cutter passes by the nozzle opening on contact and In this case, the granules are knocked off, which are discharged from the granulation housing by a coolant which has been fed into a granulation housing which surrounds the orifice plate, wherein the motor with the aid of A suspension is movably suspended relative to the housing, but only ensures this mobility in the axial direction of the shaft, and in which an adjustment device is provided for axially adjusting the motor relative to the perforated plate. Background technique [0002] Granulation devices in which the shaft can be adjusted in the axial direction are known in many e...
