Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, specifically to a spinning machine drafting device. Background Technology

[0002] A ring spinning frame is a spinning machine that takes semi-finished roving or sliver, drafts, twists, and winds it into fine yarn bobbins during the spinning process. Sliver is drafted and twisted on a roving frame to form roving; a combing machine combs the fibers to form combed sliver; a carding machine combines the sliver and uses card rows to improve the sliver structure; the roving is further twisted and spun into fine yarn on a ring spinning frame. The ring spinning frame is the main machine in spinning. The output and quality of fine yarn are a comprehensive reflection of the quality of each step in the spinning process.

[0003] A search revealed Chinese Patent Publication No. CN212533254U, which discloses a drafting device for a spinning frame, belonging to the field of textile technology. The device includes a support section, an annular track disposed on the surface of the support section, and a winding mechanism disposed on the support section. The winding mechanism includes a winding roller for winding the yarn and a rotating motor for driving the winding roller to move within the annular track. During the winding process, the raw yarn passes through the winding roller on one side of the winding mechanism and then to another winding roller to begin winding. The yarn between the two winding rollers forms an "S" shape. The rotating motor drives the two winding rollers to rotate synchronously in opposite directions within the annular track. This invention discloses a drafting device for a spinning frame that uses the tension generated between the yarns as the drafting force through the circumferential motion of the winding mechanism, ensuring the uniformity of the drafted yarn. However, while this application can guarantee the uniformity of the yarn, the yarn surface may become fuzzy during the drafting process. Completing the drafting process without addressing this issue can easily affect the quality of the yarn. Utility Model Content

[0004] 1. Technical problem to be solved by the utility model

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a drafting device for a spinning machine.
