Roving drawing -- Wuxi He Zhan Intelligent

Function of drawing frame: improve the internal structure of sliver, so as to improve the uniformity of long segments, and reduce the weight unevenness, so that the fiber in sliver is straight and parallel, reduce the bending hook, so that the fineness meets the requirements. Make the raw materials of different kinds or different qualities mix evenly to reach the specified mixing ratio. The drawing frame is divided into two categories according to the form of drafting mechanism: roller drawing frame and needle combing frame. There are many kinds of cotton drawing frame, such as single eye, two eye and four eye. Feed a number of slivers, after merging, draft made into a sliver called monocular drawing machine; The output of the two slivers is called a two-eye drawing frame, and so on. Each drawing frame has a separate transmission system. The drawing frame consists of a feeding part, a drafting part, a strip part and some automatic devices.
