Description

The present invention is intended for the automatic manufacture of raw brick by means of a pressing device and a turntable with molding cavities, the press being provided with an ejector molded brick device transmitting the latter to a conveyor belt.

In the drawing of Fig, 1 depicts the proposed press in front; FIG. 2 is a side view of the press; FIG. 3 is a top view; Figs, 4 - 9 - degili the proposed device.

The press consists of a shaft 1 (figs, 1, 2, 3) rotating in bearings 2 and 3 with the help of gears and pulleys from the engine. In the center of the press is located, freely engaging the shaft 1, column 4, in which a vertically set is fastened with a nut 5a shaft 5, with pipe 56 fitted on it, which is provided below with a conical ratchet teeth 20, and bolted with a rotating place with it on the shaft 5 a table equipped with four cross-shaped forms b, ba, 66, 6c with pressing bottoms 7, 7a 76, Those. Above the form 6a, there is an abutment plate 33, one end being dressed on a vertical shaft 5 and

fastened to it with a nut 5c, and another replied on column 8. Above the rotating table, in addition to the designated support plate 33, there is a plate located above forms b, 66, b, which is also worn on the shaft 5 and rests in addition to the columns 9, 10, 11 (figs, 1, 2, 3), Above form b (figs, 1, 2, 3), a funnel 51 is located, from which clay flows by gravity into the specified form as the form approaches under the funnel as the table rotates. In the form of a rotating table ba at this time, clay is compacted by pressing the bottom 7a pressing on the rolling pin below, running in the guide 12 of the rod 13 equipped with a roller 14 rolling along the eccentric 15 (Fig. 1, b, 8) fixed on Shaft 1. Eccentric 15 to increase pressure force, as indicated in FIG. b and 8, gives, at different points in its rotation, a different speed of lifting of the roller 14. Thus, when the clay starts to squeeze, when this compression is easy, the roller 14 quickly rises; then the eccentric 15, all with a lower and lower speed, lifts the roller 14 and at the end of the revolution the latter has an insignificant speed close to zero. The eccentric with a roller is made of iron and must be well cemented and hardened. From the mold 66, the raw material is pushed out at this time with the help of the lever 16, which is set in motion when the rod 13 is raised and the studs 17 fixed on its head 17. The table is turned using the gear sector 18 (Fig. 1, 4), one end of which sits on the axis 18a, and the other has a toothed braid, coupled to a ratchet bevel gear 20, fitted, as stated, onto a tube 5c rotating on a shaft 5. The toothed sector 18 is rotated by a roller 19 in its shaped opening (FIG. 1 , 4), mounted on the rod 19a, so that when the deviation of sector 18, the latter with its serrated braid turns the ratchet servo by 90 °. When deflected to the other side, the ratchet teeth, as a result of a definitely directed dog, rotate freely and return to their original position. Thus, at each complete rotation of the shaft 1, the rotating table is fed into one mold, rotated 90 °. The shooting of a brick pushed out of a mold 66 is as follows: on column 10 on an axis, lever 21 is loosely attached (Fig. 1, 2, 3), at one end of which there is a plug 21a, enveloping pin 216 inserted eccentrically in the end of shaft 1, and on the other -toothed sector coupled with gear 22, which is mounted on a roller 23, equipped with a crank 24, articulated pivotally with a lead 25. The latter, in turn, is articulated two with plates 26, each having a single, loosely inserted hairpin 27 and provided with them springs 28. Connected d Another plate 26 is free to stand on the rails 29 (Fig. 1, 2, 3, 5), which are provided with grooves 30 and 31 (Fig. 3, and 5). Thus, when the shaft 1 rotates, the lever 21 and the tilting of the production one way or another, with its toothed sector at this time, rotates the gear 22 accordingly, which by means of the crank 24 and the driver 25 communicates the plates 26 with a variable reciprocating motion along the rails 29. When the plates 26 are moving forward, the studs 27 are guided by the grooves 30, as a result of which the plates compressed by the springs 28 firmly enclose the molded brick, feeding it onto the belt conveyor 32. Next, the plates at the end of the grooves 30 (Fig. 5) open, The pitches fall onto the indicated conveyor, and the reverse movement is performed by the plates in the decompressed state along the guide grooves 31, which for this purpose in places 31a (Fig. 5) make deeper grooves 30. At the end of the reverse movement the plates 26 are again compressed and seized just formed brick, then to carry it back to the conveyor. The thrust plate is lubricated as follows: in the fixed thrust plate 33, the ZZa mirror (Fig. 6) is freely enclosed in guides and is fitted on top with a cremallere 336 coupled to gear 34 sitting on a roller, on the end of which another gear 35 is mounted (Fig 1, 3, 6), coupled with the toothed sector of the lever 36. The opposite shoulder of the lever 36 is provided with a roller 37, forcibly moving in a furrow 38, mounted on the shaft 1 of the wheel 38a (Fig. 1 and 9, where the wheel is presented in expanded form). The roller 37, going along the furrow 38 in a certain place, deflects the shoulder of the lever 36 first to one side and then to the other side, as a result of which the other shoulder turns gears 35 and 34 with its toothed sector, of which the third gear pulls the mirror ЗЗа to pulls it over the felt impregnated with a lubricating fluid lying in a box 39, fortified at the top of column 10, and now puts the mirror in its place. Lubrication of the walls of the molds takes place as follows: in the pressing bottoms 7, Ta, 16, 7c, at the points of contact with the walls of the molds, felt 40 is laid (Figs. 3, 6, 7) wetted through the grooves with a liquid placed in the recesses 41 of the pressing bottoms where it is poured from time to time. To release air from the compressible mass, channels 44 are provided, located in screws 43 (Fig. 7), which bind the face of the bottom with its base. For stopping the rotating table at certain places, there is a lock of the following device: on the wheel 38a there is a tide 45 at a certain place (Fig. 1, 9), while rotating the wheel 38a, the roller 46a, which is at the end one arm of the lever 46. The other shoulder of the latter at this moment is retracted by the rod 48 sitting on the spring in the fixture 47 (Fig. 3), as a result of which the latter comes out of the sockets 49. Until the turntable stops, the lever 46 releases the rod 48 and the last one press the spring enters the socket 49 and stops the turntable at a certain place. Before entering the funnel 51, the clay must be well prepared, passed through sieves or other devices that can be set in motion from the shaft 50.
