Abstract

The invention discloses a three-roller double-zone upper-and-lower-rubber-ring drafting device for ring spinning frames, which comprises a first drafting zone and a second drafting zone, the first drafting zone comprises a front roller and a front rubber roller, a middle roller and a middle iron roller are arranged between the first drafting zone and the second drafting zone, a lower front pin is arranged by one side of the middle roller, a lower front rubber ring is arranged on the middle roller through the lower front pin, and a front rubber ring is arranged on the middle iron roller; the second drafting zone comprises a rear roller and a rear iron roller, a lower pin is arranged by one side of the rear roller, and a lower rear rubber ring is arranged on the rear roller through the lower pin; an upper rear rubber ring is arranged on the rear iron roller. The three-roller double-zone upper-and-lower-rubber-ring drafting device has the characteristics of simple structure, convenience in use and little influence on transferring operation, can be popularized for use on various simple back drafting type drafting systems, and realizes the enhanced control of the back zone drafting process in order to greatly increase the back zone drafting multiple, consequently, the overall drafting multiple is increased greatly, and while yarn quality is stabilized, yarn level is ensured.

Description

technical field [0001] The invention relates to a drafting device for textile spun yarn, in particular to a drafting device for a three-roller double-zone upper and lower apron of a ring spinning frame. Background technique [0002] Textile spun yarn drafting system is the most critical part that reflects the performance of the spinning frame and affects the quality of the yarn. From the perspective of the overall spinning system engineering, the potential for improving the quality of the yarn and improving the evenness of the yarn is mainly in the drafting system of the spinning process. . The drafting process in the back area of ​​spun yarn plays an important role in the drafting area of ​​the spun yarn. The quality of the sliver in the back area is related to the level of yarn formation, and it is also the basis of the drafting quality in the front area. At present, the second drafting zone assembly of the textile spun yarn drafting system is composed of simple rubber ro...
