Abstract
The utility model provides an INA V type draft back zone pressure roll device of a ring spinning frame. A support pressure roll is arranged between a rear first roller and a rear second roller; a groove is formed in the middle of the surface of the roller wheel of the support pressure roll and is supported on a support steel wire fixed between the head and the tail of the ring spinning frame through a tension mechanism; wherein, the lower concave surface of the groove of the roller wheel and the upper surfaces of the two rollers are in the same level; and a strand is supported on the groove of the roller wheel. The strand from the rear first roller is straightened by the support pressure roll, so as to reduce the additional frictional force of the strand to a counter-surrounded arc formed on the lower side of a rear second upper roller, help to solve the problems of 5.5m counter-surrounded arcs in back zone, and reduce short fibers remarkably. Besides, the rotatable support pressure roll structure brings the accelerated point of fibers ahead, thereby improving the dispersing structure of the strand, leading the draft process in front zone be more reasonable, effectively improving the quality of finished yarns, and reducing filoplume.
