An adjustable yarn doubling device and its adjusting doubling method

Abstract

The invention relates to an adjustable yarn doubling and twisting device and an adjusting, doubling and twisting method thereof. The adjustable yarn doubling and twisting device comprises a bottom plate, a support frame, a doubling and twisting device and a winding device, wherein the support frame is arranged at the upper end of the bottom plate; the cross section of the support frame is of a U-shaped structure; the doubling and twisting device is arranged in the support frame and is arranged on the bottom plate; and the winding device is arranged in the middle of the upper end of the supportframe. According to the adjustable yarn doubling and twisting device, the problem that yarns are poor in winding effect and prone to loosening due to the fact that single yarn cannot be accurately driven to rotate when twirled by existing equipment, and easily slips, and the problem that the existing equipment is poor in pressing effect and inconvenient to adjust while pressing the doubled and twisted yarns and can only press the yarns with the same diameter to affect the processing efficiency of the yarns can be solved.

Description

technical field [0001] The invention relates to the field of yarn doubling and twisting equipment, in particular to an adjustable yarn doubling and twisting device and an adjusting doubling and twisting method thereof. Background technique [0002] Yarn co-twisting is the process of twisting two or more filaments or fiber bundles in the axial direction so that they are entwined into yarns or strands. After twisting, the fibers originally parallel to the fiber axis become helical, and the relative rotation or angular displacement occurs between the sections of the sliver, and the twisted yarn has certain strength, elasticity, elongation, luster, hand feeling, etc. physical and mechanical properties. [0003] At present, the existing yarns usually have the following defects when they are twisted and twisted: 1. When the existing equipment twists a single yarn, it cannot accurately drive the yarn to rotate, and the yarn is prone to slipping 2. When the existing equipment comp...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that the existing equipment cannot accurately drive the yarn to rotate when twisting the single-ply yarn, and the yarn is prone to slipping, resulting in poor winding effect between the yarns and easy occurrence of loose yarns. phenomenon, and when the existing equipment compresses the yarn after parallel twisting, the compacting effect is poor and the adjustment is inconvenient. It can only compact the yarn of the same diameter, which affects the processing efficiency of the yarn and other problems.
