SU45826A1 - Wool Blending Device - Google Patents

Description

The issues of blending wool and preparing it for carding are among the most relevant for the cloth industry. In order to achieve the correct mixing of the raw material, a method of mixing was already proposed, consisting in the fact that the individual components are supplied in certain portions by means of feeders installed along the conveyor, which are periodically activated and switched off only after the portion of wool is discarded by all the feeders. In order to fully resolve the issue of uniform mixing in the proposed device, designed to automatically compose a multicomponent blend, the portion of the component weighed by the weights on any feeder is not ejected from the weighing pan until the weights are weighed. Other portions (throws) compensants. Only after the portions are weighed by the rest of the feeders, a complete electrical circuit is closed / and the weighing panes are opened, which causes simultaneous ejection of individual portions of the raw material to TpajicnopTep, supplying the mixture to the pinch machine, from where

it is conveyed by means of conveyors to the second plucking machine, and then pneumatically into the stores.

In FIG. 1 shows a diagram of the general form of the device; FIG. 1-part rotating socket; FIG. 2-First, second and part of the third feeder; FIG. 3-the last (according to the sixth drawing) feeder, the first plucking machine and the second plucking machine, standing perpendicular to the first one, as well as a conveyor belt transferring material from one machine to another; FIG. A 4-pin electrical circuit that simultaneously controls the opening of the pan and the stopping of the inclined feeding grids.

The proposed device for blending wool consists of a series of feeders I-VI installed along the conveyor, supplying the mix to the plucking machines I, 1G.

Each of the feeders consists of two side support frames 1, which can move on the rollers 2 along the rails 3 and fastened with corresponding links. The entire width of the feeder passes the roller 4, to the ends of which by means of screws 5 on each side of the feeder weighted crc are attached

Arrows 6 can be pumped around prism 7. The weighing cup 8 is at rest at one end of the weight arm 6, and at the other end is the load 9, balancing the weight cup and the raw material on it. In the lower part of the feeder, the shaft 10 runs the full width of it, at one end of which is located a ratchet 11, brake pads (not shown in the drawing) and a pulley 13, transmitting the movement of the pulley 14, which sits on the axis 15 of the driving roller 16 lattices 17.

jHa the other end of the shaft 10 tightly fixed two pulleys (not shown in the drawing), transmitting the movement; one of them — on the balancing layer — is a removable ridge 20, and the other is on a removable ridge 21. The ridges 20 and 21 are their axles in bearings (not indicated in the drawing), moving — which can change the distance of the ridges from the inclined the lattice 17.,

Before each feeder there is a sizing device (Fig. 2), consisting of a trough 23, into which a sizing emulsion enters from a special tank in the side of the installed tank. At both ends of the shaft 24, two rocker arms 25 are fastened. The corresponding ends 26, 27 are connected by thick rods 28, on which the scoops 29 with counterweights 30 are hinged. The 29 emulsion is transferred to the trough 31 in which the smooth slowly rotates; (ground) roller 32. During rotation, the surface of the latter is moistened with an emulsion, removed by a brush 33, which during rapid rotation sprays the emulsion over the layered raw material on the conveyor belt.

Raw materials of various kinds, battered and cleaned and to some extent plucked, are fed by hand into feeder boxes, transported by inclined grates 17 to the removable ridge 20 and fed into the weighing pan 8, which occurs until a portion of raw material is weighed out. . At the end of the weighing portion (throw) the weighing pan 8 strives to overcome the weight of the grooved counterweight 9 at the end of the rocker arm 6 and, with the help of the contact arm on the other end of the rocker arm (Fig. 4), closes the electromagnet circuit, 35, which draws iron inside the core 36, due to which the ratchet 11 connected to the brake pads of the inclined lattice 17 is braked, on the other hand having a connection with the pulley 13, transmitting with the help of a belt drive a movement of the pulley 14 which is rigidly mounted on the axis 15 of the drive roller 16 This lattice 17. Thanks to this connection and the operation of the spine mechanism, the feeding grid 17 quickly stops and stops supplying the raw material to the scale pan 8.

As soon as the batches are weighed, a common contact of the electromagnet 37 circuit with the cores 38 is obtained. The core 38 is slowly drawn into the inside of the electromagnet 37 and with the help of the lever system connected to it, the weighing pan 8 is opened, and all the weighed portions are simultaneously thrown out and form As usual, a continuous canvas entering the conveyors 39C which transfer the material to a common conveyor 40, passing under the weights of the feeders and transferring the layered bed to the first tweezer. The resulting common layer, consisting of separate layers of various kinds of components, is fed by the nursing rollers 41 and is subjected to the processing of the pinching pegs 42 in the direction perpendicular to the feed direction.

CANVAS.

After the process of chipping the mixture under the influence of the air flow created by the wind 43 and the fan pulling the air out of the channel through the mesh drum, is forced to attract a uniform layer to the mesh drum 45 due to its uniform velocity. The layer from the drum is removed by a grooved (wooden) roller and is supplied by the output grille 46 I to the conveyor 47 transmitting the material from one machine to another. i Transporter 47 consists of three pairs of grids. The last couple, from which / the material goes out onto the table 49 of the j-ball machine (Fig. 3), has a reciprocating movement horizontally, and because of this, the layers are laid one on top of the other, but not the full area than additional additions are achieved. The number of complications can be reduced due to the difference in speeds of the mesh drum: 45 of the first tenoning machine G and the speed of the feeding grid 49 of the second plucking machine 1G. The greater the speed of the mesh drum 45 of the first plucking machine; the thinner the layer transmitted to the second plucking machine. It is possible to make a large number of additions from a thin jke layer and thereby increase the uniformity of mixing. The raw material after the tweezer is transferred to the storage bases of the carding compartment by means of a pneumatic conveyor 50. The common duct in the storage compartment 51 is divided into three sockets 52 rotating around the centerline of the storage depot. Such a rotating duct produces an additional mixing, since it spreads the raw material in a fluffed state with concentric overlapping layers. An unevenly oily blend in hardware combing affects unequal weighted portions in volume, and differently greasy fibers behave differently in the process of combing, which leads to unevenness both in thinness and in strength. Therefore, before each feeder there are, as has already been said, separate oiling devices, since the thinner layer can be oiled more evenly throughout its thickness, and the lubricating emulsion can be distributed and adhered to all the fibers before the whole mass is pinched. This means that it is possible to achieve uniform oiling of the fiber throughout the entire mixture and the ability to regulate the intensity of oiling of each component separately. The subject matter of the invention. 1. A device for blending wool, consisting of a series of feeders installed along the conveyor, supplying the mixture to a tweezer or the like, characterized in that. for simultaneous ejection of the Separate portions of wool by all the feeders of the weighing pan 8 are connected by means of lever systems With the cores 38 electromagnets 37, the input is; connecting to the common electrical circuit and included for the purpose of opening the scales cups 8 when the cores are pulled in after the circuit is closed with coroys of 6 weights when the cups are lowered (Fig. 4). 2. In the device according to claim 1, for stopping the movement of the jib of the feed grid 17 of each of the feeders for a certain portion weighed, an electroGNit 35, activated when the circuit is closed by a contact at the end of the rocker arm 6, the core 36 of which is connected to the lever used to slow down the ratchet 11, grilles sitting on the shaft 10 (Fig. 4 and 2). 3. When the device according to paragraphs. 1 and 2, for greasing each of the components separately of the device consisting of the brush 33 and the roller 32 placed in the trough 31, into which the sizing emulsion is fed by means of the scoops 29 with counterweights 30, widely mounted on the rods 28 of the rotating rocker arms 35 Sfig. one). 4.When the device according to paragraphs. 1-3, use for uniform spreading of the mixture in the base 51 of the rotating pipe pipe 52, which is put on the end of the pipe j of the pneumatic network and consists of three three elbows of different lengths arranged at an angle of 120 ° to each other.
