Abstract

The invention relates to the grinding of materials, namely, installations for grinding tires and other large rubber waste. The purpose of the invention is to increase the degree of grinding. The installation comprises shafts I mounted on bearing supports with the possibility of rotation towards each other. On shafts 1, disks 7 with knives 8 are fixed. Above shafts 1 axles 10 are installed parallel to them. Between disks 7 on shafts 1 and axles 10 there are asterisks 9 and 1I, on which infinite chains 12 are put on. covers I3. Drive rollers 18 are mounted between casings 13 and chains 12. The material being cut is fed between shafts 1, where it is cut into pieces and pressed between disks 7. Material pieces 25 that are stuck between the disks are caught by chains 12 and rollers 18 and fed into the loading zone on re-grinding. Efficiency improvement is achieved by increasing the dispersion of the crushed material due to the possibility of injecting it for re-grinding. 4 il. Ci

Description

eleven

The invention relates to equipment for the processing of polymeric materials and can be used in various production sites for grinding poker and other large rubber waste,

The purpose of the invention is to increase the degree of grinding.

FIG. 1 shows the proposed installation; a cross-section in FIG. 2 is a section AA in FIG. 1; Fig, 3 - section bb in Fig.1; in fig. 4 - incision fng. (turned).

The installation for cutting large rubber waste contains shafts 1 mounted on bearing supports 2 in parallel with the possibility of rotating towards each other from water (not shown) through gears 3 ,, 4 and 5. The shafts 6 with knives 8 are fixed with shafts 6 Between the discs, sprockets 9 are planted on the shafts, simultaneously serving as spacers. Above the shafts 1, axles 10 are fixedly mounted parallel to them, on which they are planted against each asterisk 9 with the possibility of rotation of the asterisk P. On the asterisks 9 and P are put on. endless chains 12.

Above the infinite depots 12 and asterisks 11 are installed J3p enclosures covering them, on the inner surface of which rigid ends are fixed from bulged edges 14, the lower ends 15 of which are parallel to the chains 12 and the upper ends 16 are bent in the direction perpendicular to the chains 12, to the middle of the shafts 1.

In the space between the housings 13 and the chains 12, through the windows 11, made in the housings 13, rollers 18 are installed with rigidly secured to: and their ends, the stars 19, associated with a rotating drive (not shown), the rollers 18 can be equipped with studs to grip the pieces material. Between asterisks 9 and 11 are installed inserts 20 of antifriction material with notches 21 and 22 on the upper and lower ends 5, covering the asterisks 9 and 11, and with shoulders 23 on the lateral CToipOHax for supporting the rollers of the chains 12.

P7.

The machine works as follows

The 2D material being cut is fed to the cutting discs 7 between shafts 1, the passage between the discs, the material is cut into pieces 25. During the cutting process, pieces 25 are compressed and pressed into the space between the discs 7, the pieces 25 that are stuck between the discs 7 are caught by chains 12 and the rollers 18 and fed to the feed zone for regrind. Extreme long pieces of material 8 pass under the casings 13, meet on their way curved ribs 4 and, turning: they are paralleled by 71 LINE sides: about the axes of the shafts 1 5 are re-cut: into several parts

The small pieces 26 that are not stuck between the discs fall down.

Due to the possibility of returning the pieces of material for re-grinding, a higher degree of dispersion of the crushed material is achieved without the use of additional equipment, since the return of the pieces occurs to a certain degree of dispersion while the first pieces are crushed are clamped between the disks.
