Single-spindle controllable condensed spinning device and condensing method

Abstract

The invention provides a single-spindle controllable condensed spinning device and a condensing method. A hollow structure large roller is adopted as a front roller, a circular closed hollow air suction insert is arranged between the hollow structure of the roller and a roller shaft, the air suction insert is embedded in an inner wall slide of the hollow structure of the roller by a roller drivenby a motor, an air suction groove is formed in the circular surface, adjacent to the inner wall of the hollow structure of the roller, of the air suction insert, the left side surface or the right side surface of the air suction insert is connected with a branch pipe through a closed bearing in a communication manner, and the branch pipes of two adjacent spindles are connected with a middle pipe in a communication manner. During use, the motor drives the air suction insert to rotate around the inner wall of the hollow structure of the roller, so that relative rotation between the air suction groove and the roller is realized, the time when the air suction groove is located right below the inner wall of the hollow structure of the roller and the relative position are controllable, controllable condensing of single spindle is realized, and random controllability of style characteristics of yarn surfaces under different condensing actions is realized.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a single-spindle controllable compact spinning device and a compact method. Background technique [0002] Compact spinning, also known as compact spinning, is a new type of spinning technology that is spun on an improved ring spinning frame. It improves the yarn quality by adding a fiber condensation area before the ring spinning frame traction device. At present, the mainstream types of compact spinning in the world include mesh ring type (mainly including German Sussen three-roller mesh ring type, Japan Toyota four-roller mesh ring type), roller type (Swiss Rieter COM4), punching Apron type (mainly including Zinser perforated apron type), mechanical type (mainly including Swiss Carlos Roscraft magnetic compact spinning system), mesh ring type, roller type and perforated apron type are negative pressure airflow concentration methods . Among them, Roscraft’s mechanica...

AI Technical Summary

Problems solved by technology

Among them, Roscraft’s mechanically concentrated compact spinning system is currently less used in China due to poor variety adaptability (generally only suitable for spinning yarns below 60Ne); Zinser’s perforated apron system has poor variety adaptability ( Generally only suitable for wool spinning) and need to introduce the whole machine, the price is expensive (average 1500 yuan per spindle), so the scale of use in China is small

Therefore, the current mainstream market is the mesh ring compact spinning system, but the transformation and maintenance costs of this type of compact spinning system are generally high, the energy consumption is high, and the agglomeration effect is not easy to control.
