Description

At present, mica to be cleaved comes in the form of plates of natural origin, which are divided into thinner plates in accordance with the required varieties; then these plates are glued to sheets suitable for consumption. In view of the non-standard nature of the natural plates, the splitting of mica is associated with significant jamming, to eliminate which a machine is proposed, in which the splitting of mica comes from mica previously sorted and put together in a bundle with the help of an angle, the horizontal bundle of which serves to lay on it mica, and vertical walls — for pressing mica edges to them.

In the schematic drawing of FIG. 1 is a side view of the machine, in partial section; and FIG. 2-3-gon.

A sleeve 2 is attached to the bed 7, into which a rectangular shirt 2 / is inserted, the internal dimensions of which are different for mica columns of different numbers. To facilitate the connection of mica in a pack, the square of FIG. 2 and 3, a horizontal wall 28 of which serves to lay on it

mica, and vertical walls 29 and 30- for pressing mica with its edges (Fig. 2 and 3).

The correct corner of the post, which was obtained by gluing it in a square, is positioned when inserted into the sleeve 2, so that the two springs 22 press it to one of the corners of the rectangular shirt.

On shaft 75, receiving a rotation from the pulley by arm, the crank J8 is strengthened, which with a connecting rod drives the slide with the knife 24 fixed on them.

The sled runs each time with the guides J9 on the table 23. During each course of the ssag, one thin mica plate is split, the thickness of which can be adjusted by changing the vertical feed of the bar. During splitting, the plate is kept from being crushed by a spring-loaded rod 9, and for the thin plates it is possible to put a mushroom tip covering the plate on its end. The bolt with a nut 75 fastens to a bed, 7 support J4. At the end of the knife stroke, the wedge J3, fastened with a knife, acts on the roller J2, lifts the rod 9, releasing the split plate, which is carried by the fan through pipe 25 into the chamber 25.

An eccentric 77 is fastened on the shaft 76, so that the crank lever 7, t tu b, oscillates by means of the pull of 8 and, using a dog not shown in the drawing, rotates the ratchet wheel with jerks when the knife is in the left extreme position outside the limits mica column. The ratchet wheel rotates the lift screw 5 by means of a sliding key and periodically feeds the post using a detachable nut 5.

At the end of the splitting, the nut J5 is released and the rod 9 is pushed aside. The crochet is removed by a hook and goes to a new sticker on the guide square. The nut 3 is opened and the lifting screw is lowered down, after which the machine is again ready for action.

The subject invention,

1. A mica splitting machine using a reciprocating moving knife and fed xpanoBOfi with a transfer of supor with mica, distinguished by using a spring rod 9 mounted on the frame, which presses on top of the mica bundle during splitting, equipped with a roller / 2, designed under the action fastened from the wedge /, for carrying out, at the desired time, the forced clamping of the rod P (Fig. 1).

2. When a machine tool is used in Section 1, it is used to lightly connect mica into a pack of a square (fig. 2, 3), the horizontal wall 28 of which serves to lay mica on it, and the vertical walls 29 and 30 to press mica to them with its edges .
