Abstract
The invention discloses a spinning section enhancing device for a ring spinning frame, belonging to the field of textile machinery. The spinning section enhancing device for the ring spinning frame comprises a front jaw consisting of a front leather roller and a front roller, wherein a spiral compression roller with a spiral thread on the surface is arranged in the downstream part of the front jaw through a spiral compression roller supporting piece, a spiral roller with a spiral thread on the surface is arranged in the downstream part of the spiral compression roller through a spiral roller supporting piece, and the spiral threads on the surfaces of the spiral roller and the spiral compression roller are opposite in direction. A sliver bypassing the spiral compression roller enters into the spiral roller, and the spiral roller and the spiral compression roller are connected with a driving part. When the spiral compression roller and the spiral roller rotate, the motion curves of the spiral lines on the surfaces can be divided into transverse and longitudinal sub motions, so that the silver is positively conveyed forward while being falsely twisted, thus, guaranteeing that the sliver is free from extra damage. Meanwhile, two false twisting contact sections are adopted, so that the false twisting efficiency is high, the lateral deviation is compensated, and the spinning section enhancing device is more convenient to operate and maintain due to the structure of the movable spiral compression roller.
Description
Technical field
The present invention relates to spinninging technical field, relate in particular to a kind of ring throstle spinning section intensifier.
Background technology
Ring throstle in the twisting winding process due to resistance twist with twist with the fingers sunken effect, the few 5%-10% of average ratio of twist resultant yarn on spinning section yarn left and right, one of powerful four parts of only having yarn strength of spinning left and right, in the twist triangle zone twist still less, almost without turn, this just produces two problems, and the one, spinning section weak twist district easily produces broken end; The 2nd, a little less than the twist triangle zone control, cause yarn strength low (brute force of whole yarn much smaller than cross section in all single fibre strength sums), filoplume is many.Two solution routes are arranged at present, the one, increase into twist per unit (the true sth. made by twisting), even if but also can bring the adverse effects such as per unit area yield reduction, unit power consumption increase, feel hardening, gloss variation within critical twist; The 2nd, adopt false-twisting device at spinning section, Feng Jiangnan, Huang Jianming, Ni record in " cotton textile technology " 2013 the 3rd phase 59-64 page " feasibility analysis of spun yarn false twisting spinning mechanism commercial application ", existing spinning section false-twisting device has six classes, but all there is longitudinal sliding motion friction problem violent between false twisting element and sliver, sliver is caused to additional injuries, need to improve solving.
Summary of the invention
The object of the invention is to propose a kind of ring throstle spinning section intensifier, it is not increasing under the true prerequisite of twisting with the fingers of resultant yarn, making the false twisting of spinning section meet or exceed resultant yarn really twists with the fingers, thereby enhancing spinning section, the compression twist triangle zone, improve yarn strength, reduce filoplume, reduce broken end, can ensure that sliver is not subject to additional injuries simultaneously.
For reaching this purpose, the present invention by the following technical solutions:
