Research on Application of Inverter
Controlled by Computer in Roving Frame
Abstract
In traditional roving frame, the complex mechanical transmission and control system is adopted, which includes a pair of long prick wheel, quite a few groups of transforming gears, and springs, ratchet wheels and levers. Because of nonlinear error in the mechanical transmission system, the control on the tensile force of yarn is unstable, the precision of transmission is low, and the dynamic response is dull. Further more, calculation of process and changing varieties is very troublesome, the range of changing varieties is small, and the actual process value has some difference with the value in theory, which limits further enhance in output and quality of product. New roving machine using computer-controlled motor Frequency Control, respectively, drawing transmission system, the spindle system, Chien Lung tendons of the system and take-off and landing system, so that the roving drawing, twisting and winding shape, according to computer technology and Winding Roving Forming the software instructions control the motor speed, precision Roving completed the process.
However, the use of all the transmission mechanism of the programmer despite the perfect comparison, the high cost of this transformation, to achieve the more complex process. In this paper, transforming A453B-roving machine for example, by remove the differential me directly to the electrical received bobbin axis of the programmer. Simple structure and easy operation and lower costs, easier to achieve.
