Description

The invention relates to machines for the manufacture of drani, in which rollers are used to feed the workpiece, and an endless chain with knives is used as a tool. In the proposed machine, the knives, which are rotatable near a fixed Axis, are made adjustable on the inclined platform of the parts associated with the chain links. By a corresponding rearrangement of the knives at the indicated inclined platform, a change in the thickness of the produced dranium can be achieved.

Knives 4 (Fig. 1, 2), used in the proposed fixture, are reinforced with the possibility of permutation on an inclined platform 5 parts 17 (Fig. 4-7), rotatably fixed on axles 2 to links x 6 of an endless chain of fixture. The knives 4 are provided with a bevelled platform adjacent to the platform 5 of parts 17 (Fig. 5, 7, 8), as a result of which the knives can be displaced along the said inclined platform by the required value b (Fig. 8) in order to change the thickness of the produced dranium. The knives 4 are placed between two springs 1 and 3 (Fig. 3) attached to the rails 7, and at offsets along the platform 5 they approach or move away from each of the rails 7.

The endless chain 6, on which the knives 4 are fastened and which serves to feed the knives to the workpiece (Fig. 9), is mounted on sprockets 18, and the knives 4 are attached to the chain in two places so that when only the knives 4 are machined others go idle. To eliminate significant deflections of the chain 6 during the working movement, it is supported by rollers 19.

The machined workpieces are delivered in the machine by grooved rollers 20 (Fig. 14), which are mounted on a roller 21 (Fig. 11, 12), one rigidly and the other with the possibility of movement along the axis of the roller 21. The roller 21 is fixed on racks 22, St. When mounted with the base 26 of the device, and for carrying out constant pressing of the rollers 20 on the workpiece, the bearings of the roller 21 are loaded with springs. At the end of the roller 21, a ratchet gear 23 (FIG. P, 16) is placed, which interacts with the ratchet shaft 24. The rod 24 (FIG. 16, 17, 18) is located in the opening of the part 25 movably fixed on the machine bed 26, and is loaded with a spring 27 The part 25 is connected by a connecting rod 28 (Fig. 16) with a pin of the rotating gear 29, as a result of which, when the gear 29 rotates, the rod 24, having performed swinging movements, then approaches, then moves away from the ratchet gear 23. The rod 24 periodically rotates gear 23, as a result of which roller 21 rotates, and rollers 20 serves the workpiece. The movements of the rod 24 are coordinated with the stroke of the knives 4 of the chain 6 and the feed is made B between the end of the treatment with one knife of the chain 6 and the beginning of the treatment with the other knives.

The table 8 of the machine (Fig. P, 12) is made movable in the vertical direction, for which the mechanism consists of 8 screws 9 connected to the table 9. The nuts for the screws 9 are located in the hubs of the screw wheels 10 (Fig 11-13), which linked with screws 11 on axis 12. Axis 12 is provided with a handle 30 and, when the handle is rotated, table 8 can be raised or lowered by the required amount.

To press the workpiece to the table during operation of the device serves

a pushing mechanism (fig. 11, 15) fixed in holes 31 of the pillars 22. The pushing mechanism consists of a moving board 32 equipped with a slot 16, in which plates 14 are fixed in a certain position by means of spring rods 15. The springs 13 are positioned by their respective movement along the notch 16 of the board 32 above the treated shingles and pressing it against the table 8.

The shredding of the workpiece is done in the following order. Table S is respectively set in relation to the rollers 20, and the knives 4 in relation to the guides 7. Then the machine is operated, the rollers 20 periodically rotated from the ratchet gear 24, 23, the workpiece pressed by the springs 13 is fed, and the knives 4 being moved chain 6, cut the workpiece into shingles.

The subject matter of the invention.
