Description

The invention relates to presses for the manufacture of tiles and the like of articles made of bulk materials, equipped with rotary drums and placed around the circumference of the latter. The movement of the dies in the specified forms for the purpose of pressing and subsequent ejection of the product is carried out using eccentrics. In the proposed press, the molds are placed on an eccentrically mounted ring on the working shaft, covered by a wheel with a press rim equipped with pads, the number of which exceeds the number of forms by the same amount as the wheel diameter is larger than the eccentric ring placed inside it. The pressing device together with the working shaft is placed inside the hopper, the bottom wall of which is provided with a side opening for ejecting molded tiles and the like from the press.

In the schematic drawing of FIG. 1 shows a section according to FIG. 2; FIG. 2-side view of the press with a partial vertical section; FIG. 3 is a section through EF in FIG. 2; FIG. 4-part; FIG. 5 is a section along the line in FIG. four.

Stepped eccentrics 2 are fixed on the inclined shaft 1, which serve for rotation of the wheel 6 and the rings 3 which are eccentrically mounted on the shaft 1 and rotate.

equipped with forms 4 with pads 5, which correspond to pressure pads 8 fixed on the inner walls of the press rim 7 of the wheel b, the number of pads being so many times more than the number of forms 4, how much the wheel diameter b is larger than the diameter of the ring 3. The pressing device is placed inside a bunker 9, the lower part of which has the shape of a cylindrical shield, provided at the bottom with a hole 10 for the deposition of molded tiles 11, etc.

The press is loaded with granular material for making tiles and the like of products into the hopper 9, from which the material flows through the open-top interdemporal space (Fig. 3) into forms 4. When the working shaft 1 rotates with the help of eccentrics 2, wheel b, the pads 8 of which, engaging with the forms 4, transmit the rotation to the ring 3. Simultaneously with the rotation of the latter, due to its eccentric fit, the pads supplied with spikes 12 pads 5 moving in the grooves of the semirings 13 fastened with the eccentric and. At the maximum extension of the pads 5 and with the pads 8 included in the forms 4 (the right part of FIG. 1), the tiles are pressed. With further rotation of the ring 3 and the wheel b

chills 8 are removed from mold 4, and pads 5 are drawn into molds, freeing the last dp of filling with a new portion of bulk material. The wheel b has a piercing, when it passes by the hole 10 in the shield, the molded product falls out of the press.

The subject matter of the invention.

A press for the manufacture of tiles and the like of bulk materials, with a rotating drum and circumferentially placed molds whose matrices are driven by eccentrics, characterized in that the eccentrics 2 are mounted on an inclined shaft 1 and are covered as an eccentric ring 3 with shapes 4 and the wheel b with the pads 8 forming the press rim 7, the number of which is more than the number of molds by as many times as the diameter of the wheel 6 is greater than the diameter of the ring 3, where all the above mentioned parts are placed in the cavity of the hopper consisting of the hopper at the bottom extending into a cylindrical shield with a hole 10 on the side to drop the molded article.
