Abstract

The invention relates to a four-roller drafting device of a ring spinning machine, which belongs to the field of ring spinning machines, and solves the technical problem of hairiness and poor yarn quality in twisted yarn sliver. Arranging the bottom roller (11), support (8), support (8) is set on the cradle (1), the support (8) is provided with accumulator (9) and arranges the upper roller (10), on the slide block (14 ) is provided with front lower pins (12) and finishing bottom rollers (11), and the accumulator (9) and bottom pins (12) are arranged on front top rollers (7), front bottom rollers (13) and finishing top rollers (10 ), arrange between the bottom rollers (11), between the accumulator (9) and the front lower pin (12), there is a slit of 0.6-1.5mm. The invention increases the total draft ratio and ensures the yarn quality.

Description

1. Technical field [0001] The invention belongs to the field of ring spinning machines, in particular to a four-roller drafting device of a ring spinning machine. 2. Background technology [0002] The ring spinning frame is a commonly used textile machine, which is used to twist and spin the cotton yarn strands into required spun yarns after step-by-step drafting. When the ordinary ring spinning frame is working, the fiber strands are drawn by the rollers in the drafting area. The impact of pressure makes its cross-section flat. When the fiber strands are sent out from the nip of the front roller, they enter the twisting zone and rotate at a high speed under the action of the lower traveler to complete the twisting action, thus forming a so-called "twisting triangle zone" at the nipper of the front roller. Due to the existence of the twisting triangular area, the fibers in the fiber strands are unevenly stressed during the twisting process, and the fibers are rotated inside...
