Slotted negative-pressure disc-type multi-cluster spinning method and spinning mechanism

Abstract

The invention provides a slotted negative-pressure disc-type multi-cluster spinning method. The method includes the steps that 1, roving is unwound from a roving roll and enters into a drafting zone for drafting, and a fiber strand is formed; 2, the drafted fiber strand is output through a jaw composed of a roller and a rubber covered roller; 3, the fiber strand output in step 2 continues to be output in a semi-relaxed surrounded environment in the periphery direction from top and bottom and left and right; 4, then, the fiber strand output in step 3 is transported in a negative pressure adsorption mode, and integrated composite spinning with better mightiness and uniformity is formed; 5, the integrated composite spinning formed in step 4 is wound to form a spun yarn roll. According to the scheme, a tension cross-bar is provided with a negative pressure air intake hole structure, and therefore in the process that the fiber strand passes through the tension cross-bar, negative pressure suction generated by the negative pressure air intake hole can enter into all the parts inside and outside the fiber strand, so that the parts around the periphery of the fiber strand draw close to the center part of the fiber strand to further form a real compact spinning structure.

Description

technical field [0001] The invention relates to the technical field of tension disc multiple compact spinning, in particular to a slotted negative pressure disc multiple compact spinning method and a spinning mechanism thereof. 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 ...

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 tension disc type heavy compacted yarn spun by the present invention can effectively reduce the surface hairiness of the ring spun yarn, increase the strength of the yarn, and improve the dryness of the yarn, but the tension disc type heavy compact spinning method is troublesome to operate, and the joint The accumulating wheel needs to be lifted, and at the same time, the accumulating wheel is easy to accumulate flowers in large-scale applications, resulting in unsmooth rotation and broken ends

[0003] However, the reconcentration spinning bobbins produced by the above reconcentration spinning methods cannot withstand the winding process in the subsequent process, and the reconciliation spinning bobbin yarn has serious hairiness rebound, which shows that the yarns produced by these methods are not dense in structure. , not resistant to winding, unable to withstand friction, the spinning method is troublesome to operate, the joint needs to lift the accumulation wheel, and at the same time, the accumulation wheel is easy to accumulate flowers in large-scale applications, resulting in unsmooth rotation and broken ends
