Method for slot-type tension-disc type multi-fold integrated composite spinning and spinning structure thereof

Abstract

The invention provides a method for slot-type tension-disc type multi-fold integrated composite spinning and a spinning structure thereof. The method includes the steps that 1, rough yarn is unwound from a rough yarn reel and enters a drafting area to be drafted and form fiber strands; 2, the fiber strands after drafting are output by a jaw composed of a roller and a rubber covered roller; 3, the fiber strands output in the step 2 continue to be output in an all-directional semi-loosened surrounded environment to form multi-fold integrated composite yarn; 4, the multi-fold integrated composite yarn formed in the step 3 is wound to form a spun yarn reel. According to the method, by notching a four-dimensional semi-loosened surrounded groove in a tension cross bar for the fiber strands, when nubs of the fiber strands enter the four-dimensional groove, the nubs push up the tension disc, and then under the gravity effect of the tension disc, the nubs are smoothed out; when snicks of the fiber strands enter the four-dimensional groove, the snicks are arrayed by three borders of the groove again to increase fiber amount of the snicks.

Description

technical field [0001] The invention relates to the technical field of tension disc multiple compact spinning, in particular to a grooved tension disc multiple compact spinning method and its spinning mechanism. Background technique [0002] The spinning process is the foundation and key of the entire textile industry. The quality of the yarn produced in the spinning process directly determines the subsequent processing of the yarn, such as weaving efficiency and cloth surface effect. Hairiness and evenness are important indicators to measure yarn quality. Yarn dryness and hairiness not only affect the production efficiency of subsequent processes such as knitting, but also affect the overall appearance quality of the final product. In the existing market, some spinning manufacturers have already begun to research related technologies on yarn dryness and hairiness. For example, Chinese Patent Publication No. CN201459313U, published on May 12, 2010, the name of the invention...

Chinese Patent Publication No. CN103757762A, published on April 30, 2014, the name of the invention is a spinning method for fiberizing strands, the patent discloses a spinning method for fiberizing strands, the method On the basis of the ring spinning technology, a device for fiberizing the sliver is installed in the drafting area of ​​the spun yarn, which increases the control of the fibers in the drafting area, and can control the fibers of the sliver with the number of fibers gradually decreasing. For the smoothing effect, the front end of the device is very close to the meshing line between the front top roller and the front roller, which can significantly reduce yarn hairiness, improve yarn evenness and yarn strength, and reduce the edge of the twisting triangle area of ​​spun yarn The fiber is sucked away by the suction tube and becomes bellows, which is beneficial to improve the yield of spun yarn. However, this method can only control the fiber in the drafting area of ​​the spun yarn, and does not have any management on the fiber coming out of the front nip, especially the fiber entering the spun yarn. The fibers in the spinning triangle are not constrained, and this method does not have a significant effect on improving the ring-spun yarn

Chinese Patent Publication No. CN104357972A, published on February 18, 2015, the name of the invention is a spinning method for double aggregation of strand fibers, and a spinning method for double aggregation of strand fibers is proposed. A pre-accumulating device is installed in the front drafting area of ​​the spinning frame, and the strands are fed into the pre-accumulating device through the holding jaw composed of the upper rubber ring and the lower apron. After the output of the front nip composed of the front roller, after the accumulation treatment of the heavy accumulation device, the yarn guide hook, the steel ring and the traveler are wound on the spun yarn bobbin, and the heavy accumulation area is surrounded by the heavy accumulation area due to the lifting of the yarn guide hook The arc is constantly changing, the length of the arc surrounded by re-agglomeration is too short, and the effect of re-agglomeration is unstable

Chinese Patent Publication No. CN104357973A, published on February 18, 2015, the name of the invention is a re-concentration spinning method for adjusting yarn tension balance, and a re-concentration spinning method for adjusting yarn tension balance is proposed. A pre-accumulating device is installed in the front drafting area of ​​the ring spinning machine, and the strands are fed into the pre-accumulating device through the gripping jaws composed of the upper rubber ring and the lower apron, and the strands pre-accumulated by the pre-accumulating device After being output from the front nip composed of the front top roller and the front roller, the yarn passes through the re-accumulation device, the tension balance device, and then through the yarn guide hook, the steel ring, and the traveler, and is wound on the spun yarn bobbin. This method solves the problem of The lifting of the yarn guide hook causes the spinning tension in the re-accumulation area to change continuously, the length of the re-accumulation surrounding arc is short, and the re-accumulation effect is unstable. transmission, thereby affecting yarn dryness and strength

Chinese Patent Publication No. CN104451981A, published on March 25, 2015, the name of the invention is a re-concentration spinning method with improved re-concentration spinning enclosing arc length, and a method with improved re-concentration spinning enclosing arc length is proposed The re-concentration spinning method, the invention adopts a pre-concentration device installed in the front drafting area of ​​the ring spinning frame. After the pre-accumulated strands are output from the front nip composed of the front top roller and the front roller, the strands are re-assembled by the re-accumulation processor, and then processed by the re-accumulator with increased encircling arc length, and then led to The yarn hook, steel ring, and traveler are wound on the spun yarn tube. This method solves the problem that the re-accumulation surrounding arc in the re-accumulation area is constantly changing due to the lifting of the yarn guide hook, the length of the re-accumulation surrounding arc is short, and the re-accumulation effect is unstable. problem, but the ensuing problem is that the processing device of the heavy concentrator with the increase of the surrounding arc length has a twist trap, which prevents the transmission of the twist and affects the dryness and strength of the yarn.

The spinning method is cumbersome to operate, and the joint needs to lift the accumulating wheel, and in large-scale applications, the accumulating wheel is easy to accumulate flowers, resulting in unsmooth rotation and end breakage
