THEORETICAL INVESTIGATIONS OF THE FORMING BUNKER WORKING PARAMETERS WITH VIBRATING CONVEYERS
Theoretical investigation of the forming bunker working parameters with vibrating conveyors is carried out. An equation, allowing to determine the speed of the fibrous material movement in the forming bunker, depending on the vibration parameters (amplitude and frequency of oscillation) of the vibrating conveyors is obtained. Differential equations of the fibrous material motion along the vibrating surface, playing a fundamental role in determining the patterns of movement of the fibrous material in the forming bunker (bin) and makes it possible to adjust the values of the parameters, affecting the uniformity of fiber flooring on the supply table carding machine. The result we have received refers to the case when the vibrating surface is flat and it makes headway fluctuations while the field of forces affecting the fiber is homogeneous, and it represents a field of force of gravity. We have theoretically obtained differential equations concerning the relative movement of the fiber material on the forming bunker of a 2-cabin bunker feeder under conditions when the fiber scrap can move without leaning on the surface, at a relative rest. In that case, a new coefficient is proposed, a new parameter of reloading and also an equation of fiber sliding on the surface of vibrating transporter. We have also obtained equations, defining the law of the change of relative velocity of the fiber in case of its collision with the surface. It has been proved that the collision can be considered instantaneous, and that the change of normal velocity can be defined by Newton hypothesis. It has also been proved that the factors, such as the amplitude and the frequency of fluctuation of the transporter, the vibration angle, and the normal reaction of cotton on the surface and the resistance force to the patch movement are determining factors.
