It is desirable that the particles obtained shall be of uniform size and shape as otherwise smaller grains in the mass being heated could be burned before larger grains became sufficiently heated and softened.
Many different machines are already known for the continuous comminution of materials at high speed to obtain particles of regular, e. g. cubical, form. However such machines have the disadvantage of being exposed to repeated shocks due to the action of the rotating knives as they repeatedly strike the material to be cut. The result is a loss of motive power, appreciable noise and vibration, and premature wear of the cutting edges. Moreover, the cutting action is accompanied by the production of more or less appreciable quantities of Waste and dust, which become lodged between the preliminary co-acting cutter discs of the machine and the guides for the work material, in such manner as to foul the interior of these elements. Consequently, frequent stoppages for cleaning the machines are necessary.
The present invention provides improvements which enable these inconveniences to' be avoided, ensure an appreciable saving in motive power, result in the machine running more smoothly and quietly, and facilitate the operation and maintenance.
The invention will be fully understood from the following description aided by the accompanying drawings which show some embodiments thereof by way of example. V
Fig. 1 is a sectional elevation of one form of machine in accordance with the invention;
Fig. 2 is a detail plan view of the arrangement of the Fig. 3 is a plan view of a modified arrangemen f these knives; "I i Fig. 4 is a sectional elevation of a slightly modified form of the machine in a plane at right angles to Fig. 1;
Fig. 5 is a plan corresponding to Fig. 4 partly in sec tion along the line V-V of that figure; and
Figs. 6 and 7 show on a larger scale details of the clearing and cleaning element for removing waste and dust.
In operation the strip of plastic material 1 passes between the feed rollers 2 and 3 and thence on to the feed table 4 between the two guides 5, slidably adjustable on the rods 7 and 8 fixed on the said table. These guides 5 are locked in the required position apart by the screws 9 and 10.
The strip 1 is thus fed between the fixed horizontal upper and lower guides 11 and 12 and passes to the multiple circular cutters or discs 13 and 14. The lower guide 12 is supported at one end by a step 4a formed in table 4 and extends substantially coplanar with the surface of table 4. The set of discs 13, working between the set of discs 14, causes the strip 1 to be slit into a bundle of longitudinal ribbons.
Upon leaving the guides 11 and 12, these ribbons are cut in to nearly cubical grains by means of the knives 15 carried on the rotating shaft 16, and acting against the counter-blade 17, the speed of rotation of shaft 16 being adjusted to correspond to that of the serrated cutter discs 13 and 14. Thus it will be seen that the lower guide 12 serves as a support for counter-blade 17 while upper guide 11 serves as a support for the vertical clearing blade 18.
It will be seen from Fig. 1 that the vertical plane A passing through the axis of the cutters 13, is slightly displaced to the left with reference to the plane B passing through the axis of the cutters 14. This arrangement is for the purpose of directing downwards the bundle of longitudinal ribbons, in order to ensure that they will be effectively pressed against the counter-blade 17 when coming into contact with the knives 15.
In accordance with Fig. 2 the knives 15 are set slightly askew in order to cut the longitudinal ribbons successively instead of simultaneously, and thus afford smoother working, absence of shocks or jerks, and cleaner cuts.
The hollow bracket 19 onwhich this blade is'fitted'has its tubular element- 20connected by rubber tubingv to a source of'compressed air, hot or'cold. This air is ejected through the orifices 21, which-may be either roundholesor horizontal slits, andis principally intended to heat or to cool',.according to thematerial being processed, the
circumferences of the cutter discs 13 and 14 as well asthe material itself during the cutting operation.
Finally, the invention provides the possibility of removing from the machine integrally, the assembly of the upper discs 13,- their carrying shaft, the corresponding ball bearings 22 and bearing blocks 23, the two set screws 25,. and the two operating hand-wheels'29. The bearing,- roller-auxiliary supports assembly can'be' removed from the machine frame without dismantling any of the elements and without disturbing the setting of the graduated scale 28. This permits both the cleaning of the complete assembly of cutter discs and guides, and inspection and adjustment or replacement of these elements. It willbe seen-that inorder to remove the assembly it is sutficient to remove the screws 32. whereupon the assembly can be lifted out as a unit.
