Study of the movement of raw cotton on the surface of an inclined peg

Abstract

The article presents a study of the raw cotton movement on the surface of a throwing drum with inclined spikes of a saw gin. The considered system consists of two separate sections. The interaction of cotton with actuating tools in the first section takes place on the surface of the spike of the throwing drum, and in the second section, it occurs with separation from the spikes of the throwing drum until it hits the blade of the saw cylinder. It was determined that with an increase in ω, the path and time for the passage of raw cotton along the surface of the spike of the throwing drum decreased while the angle and height of the cotton hit on the surface of the saw cylinder increased. As a result of studying the kinematics and size of the saw gin throwing drum using the raw cotton movement, the relative velocity of cotton in the falling zone was 0.2667 m/s at an angle of 114º relative to the drum.
