SU19982A1 - Wool blending machine - Google Patents

Description

The present invention relates to machines for blending wool. The machine consists of p yes bins. whose bottom is made in the form of an infinite moving lattice. Each bunker has a vertically positioned drum, studded with pegs, which, when rotated, gathers wool from the bunker and transfers it to a comb located in the sleeve that serves to direct the wool removed from the drum when it falls onto the conveyor, layering the wool along the main conveyor along the machine . The latter transfers the fibrous material to two needle rollers, which serve to seal the layer of wool, torn and stirred by a rotating beat. The amount of wool transferred by the drum is controlled by varying the number of revolutions of the drum.

In the schematic drawing of FIG. 1, a longitudinal section through a machine for blending wool is shown; FIG. 2 - cross-section of the machine; FIG. 3 and the projection of the drum.

The machine consists of eight bunkers and eight vertical drums 1 with pegs, inserted between the teeth of the dies 22, designed to remove wool from the drum surface, which are arranged four in a row. In the top, the drum's local shaft is equipped with bevel gears of different sizes, which and rotate the drum 1 with pegs (Fig, 3). For each drum there is a gear on the shaft 20, independent of each other, with a tapered pulley 17 and a transfer 19, and the fastening fork is marked in divisions to indicate the number of revolutions when the belt moves along the tapered pulleys (Fig. 1). Between the reels 1 is placed the main transmission, on the shaft of which sits a row of paired conical pulleys 15 of different diameters, transmitting movement to the conical pulleys 17. A row of bunkers 2 for wool is laid to the drums, the bottom of which is made in the form of infinitely moving canvases 3.- From the drum to a conveyor belt 3 is provided with a sleeve 4, which serves as a guide when the wool falls onto the transverse conveyor 5. A roller 23 is used across the entire height of the drum to adjust the wool output from the hopper; along the length of the latter, several pieces of steel brushes 24 made of wire are used to clean the wool from the pegs and from the circumference of the drum 1 (Figs. -3 and 3). The transverse conveyors 5 are fixed at one end to the shaft, which sets the conveyor in motion, the other the end, by means of mechanism 7, is raised and lowered, thereby regulating the layer of the thickness of the mixed wool. In parallel with the conveyors 5, there are patches 6- so that the wool is not lost during the movement. The wool from the transverse conveyors 5 enters the common conveyor 8 with parallel-arranged slats 9 to avoid leakage of the mixed wool over which the rollers 10 are mounted, the purpose of which is to crush the wool and without which the layer of wool would be too high and fluffy (Fig. 1 and 2). From the main conveyor 8, the mixed wool in the interlayers enters the receiving rollers 11 with pegs, crushing the wool for further blending, after which the wool enters two rotating drums with beaters, where the wool is mixed with each other and fed through the conveyor to the pinch masks.

Under the conveyors 3 and 5, which receive movement from the pulleys 16 of the main transmission, there are slopes 13 on both sides, along which the wool, randomly sifting through the conveyors 3 and 5, rolls onto the conveyors 14, located on both sides of the machine and serving for removal on the main conveyor 8, the wool is again for blending. In this way, wool is saved and the intermediate space between the conveyor 8 and the foundation wall is protected from clogging (Fig. 2).

The process of working in the invented machine is as follows: wool of different varieties enters bunkers 2, and it is implied that each type of wool, depending on weight, during the mixing process enters its bunker 2. The superimposed wool in bunker 2 moves through endless webs 3 to a rotating drum 1 with pegs, where it collides with removable combs 22, from where through the sleeve 4 and the transverse conveyor 5 enters the main conveyor 8.

The amount of the hair transferred by the drum 1 is regulated by changing the number of revolutions of the drums, which is achieved by using several conical pulleys 15, 17 and replaceable gears. G of the main conveyor 8, the wool gets into the take-up rollers 11, from them to the beaters, from where it is conveyed to the plucking machines by means of the conveyor or by pneumatic feeding.

The subject of the patent.

1. A wool blending machine consisting of a row of hoppers with endless moving webs located on both sides of the conveyor along the machine, characterized in that, in order to transfer wool from the hoppers 2 to the conveyor 8, vertical drums 1 are used provided with pegs entering between the teeth of combs 22 intended for removal of wool from the surface of drums 1 and attached to sleeves 4, which serve as guides when the wool falls on transverse conveyors 5, from which the wool enters the trans porter 8 feeding the pinch machine.

2. In the machine described in paragraph 1, the application for changing the rotational speeds of the vertical drums, depending on the weight of wool in the mix, is given by the tapered pulleys 17, which sit on the same shaft 20 with the rotating drums 1 of the bevel gears and receive movement from paired gears. tapered pulleys 15, sitting on the transmission shaft.

3. In the machine described in paragraphs 1 and 2, the use of slopes 13, located under the hoppers 2, and conveyors 14, located on both sides of the machine and serving to divert wool caught on the conveyor 8.
