Research of the Interaction Impact Features of the Cotton Wicks While Hitting the Grates in the Cotton Ginning Machines

Abstract

During the cleaning process of the raw cotton, in the saw drum and grate network zone of the cotton ginning machines, the cotton mass is being subjected to the mechanical impact. At this moment, when the cotton wicks hit the grates, the cotton seed is mechanically being damaged and free fibers are being formed. When the cotton seed is mechanically damaged, its maturity decreases, and the formation of free fibers reduces the curvature/spinning ability of the fiber. Keeping the natural quality indicators of raw cotton and taking into account its physical and mechanical features, there is a great demand to conduct theoretical studies and researches for designing new machines. Taking into consideration the elastic properties of cotton wicks during their impact on the grate, the formulas revealing the movement speed of wicks and recovery of wicks coefficient were determined. The article reveals the possibility of prevention the cotton elements from damage by determining the interaction characteristics of cotton wicks with grates and by adjusting the technological parameters to the equipment before processing.
