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.

Abstract

The invention provides a drafting double condensed spinning device and spinning method. Front rollers of a drafting system adopt big rollers of hollow structures, uniformly arranged slots or holes areformed in the surfaces of the rollers, hollow air suction plug-ins fixed on the inner walls in a close attachment structure are arranged in the hollow structures of the rollers, air suction ports which are formed in a front-rear manner and located at the front parts and the rear parts of the pressing contact points of front rollers and front rubber rolls respectively are formed in the upper surfaces of the air suction plug-ins, so that fiber strands output by middle rollers are clustered under the negative pressure in the rear air suction ports, fiber at the front rollers change speed in a concentrated manner, the concentrated suction and drafting function on fiber in a front drafting area is realized, the evenness and strength of the yarn are improved substantially, condensing of the fiber strands output by the front rollers under the negative pressure in the front air suction port is realized, fiber strand compacting before twisting is realized, the overall twisting efficiency of the fiber strands is improved, the probability that fiber tips extend out of the yarn is reduced, and hairiness of the yarn is substantially reduced.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a drafting double compact spinning device and a spinning 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 mechanically concent...
