Abstract

The invention relates to the cotton gin industry and can be used in devices for loosening and cleaning fibrous material. The aim of the invention is to increase the efficiency of loosening of the material by eliminating the monotony of the effect of caustic and working bodies. The loosening drum of a fiber processing machine contains a cylindrical shell 1 with pegs 2, installed in longitudinal rows. The splits 2 of each row are located at an angle γ to the corresponding radial plane of this row with the formation of sinusoid 3 by the ends of the splitting pin, while the splittings of 2 adjacent rows are located at different angles γ to form shifted sinusoids, for example, by a quarter of their period. 4 il.

Description

The invention relates to the cotton cleaning industry and can be used in devices for loosening and cleaning fibrous material, for example raw cotton.

The aim of the invention is to increase the loosening efficiency of the material by eliminating the monotony of the effect.

FIG. 1 shows a loosening drum; in fig. 2 is the same, view A in FIG. one; in fig. 3 - the same, two adjacent rows of jabs; in fig. - options for placing pegs relative to the radial plane and the forces acting on the cotton.

The loosening drum of the fiber-shaping machine contains a cylindrical shell 1 with pegs 2 installed in longitudinal rows. The splits 2 of each row are set at an angle –j j corresponding to the given row of the radial plane with the formation of sinusoid 3 tips by the ends of the splits of 2 adjacent rows located at different angles f, sinusoids 3 adjacent rows are shifted, for example, by a quarter of the period.

Loosening drum works as follows.

The raw cotton entering the drum 1 is caught by the pegs 2 and dragged along the mesh surface. Since the pegs 2 of each row are set at an angle v to the corresponding radial plane, the pulling force has a different value. Installing pegs 2 at different angles of the drum eliminates the monotony of the impact on the bat or particles of raw cotton by creating conditions for organized multidirectional shock interactions of each peg 2

drum and cotton particles. With

This leads to an intense rupture of the bonding forces and the release of trash from the fibrous mass, which ultimately leads to an increase in the cleaning effect.

In the diagram of FIG. Shows the capping and hlp-raw flyers. The scheme has the following designations

neither: P

up - pulling force;

F - friction force Rc - centrifugal force of the volt; N, - - reaction from capping to fly.

From the diagram a it can be seen that when tilting

„P - dragging force and friction force. In the diagram b, the angle is T 90 °, and in the diagram the angle is 9 ° °. Thus, at different inclinations of the pegs, the pulling force has a different magnitude. Moreover, the slope of the pegs of adjacent rows varies sinusoidally. The proposed loosening drum of the fiber material cleaner significantly increases the efficiency of loosening and cleaning the fiber material from trash.
