Abstract
The invention relates to a drafting system of a ring spinner, which is used for solving the problem that the traditional S-type drafting system has slightly weak control force on prezone floating fiber and insufficient control force on postzone floating fiber. The drafting system comprises a main drafting assembly consisting of a middle and upper roller, an upper pin and an upper leather collar; after the drafting system is improved, the upper pin has a lengthened front edge with a bending angle, the distance R from the top of the front edge of the upper pin to the supporting center of an upper leather collar pin is 41-45 mm, the center of a front and upper leather roller moves forwards for a distance A of 2-7 mm relative to the center of a front and lower roller, and the center of the middle and upper roller moves backwards for a distance B of 2-8 mm relative to the center of a middle and lower roller. Through adding the structural size of the upper pin and optimizing and adjusting the forward moving distance of the front and upper leather roller and the backward moving distance of the middle and upper roller, the length of the fiber floating zone of a fiber sliver is shortened in the drafting prezone and the drafting postzone, the fiber is ensured to be more effectively controlled and the running stability and the controllability of the floating fiber in the fiber sliver are improved.
