Description
Technical Field
The invention relates to a lateral negative pressure guide capture type ring spinning device, and belongs to the technical field of textile processing.
Technical Field
The hairiness is one of important indexes for measuring the quality of the yarn. The yarn hairiness not only affects the production efficiency of the post-processes of weaving, knitting and the like, but also affects the appearance quality of the final product, and especially the reduction of the yarn hairiness is of great significance at present when a high-speed shuttleless loom is commonly applied.
The yarn hairiness is generated in a spun yarn processing procedure of ring spinning. The key problems of the spinning process of the common ring spinning are as follows: the front roller jaw presses and holds the fiber strand into a flat belt shape, the fiber in the flat belt-shaped fiber strand is transferred inside and outside under the action of twisting torsion force, when a certain part of the fiber enters the yarn body through the inside and outside transfer, the head end part of the fiber exposed out of the yarn body is separated from the front roller jaw to be held, and then the fiber cannot enter or wrap the main body of the yarn body again, so that filoplume is formed; when the fiber is positioned at the most edge of the flat ribbon-shaped fiber strand, the adhesion cohesion acting force between the fiber and the twisting strand main body is weak, the fiber just comes out of the front roller jaw, is easy to change the direction under the negative pressure air suction effect of the air suction flute pipe, is separated from the twisting strand main body, and is directly sucked away by the negative pressure of the air suction flute pipe after the fiber is completely separated from the front roller jaw holding effect, so that the fiber falling is formed, and the fiber utilization rate and the ring spinning quality are reduced.
Aiming at the problems of hairiness and poor yarn quality in the ring spinning process, a great deal of research is done by scholars at home and abroad. Two approaches are usually adopted, one is to optimize the common ring spinning process by adopting a conventional method, the method can only reduce yarn hairiness to a certain extent, and the action effect is limited; the other method adopts a novel spinning technology or a special hairiness eliminating device to eliminate hairiness, thereby greatly improving the ring spinning quality. A novel ring spinning technology or a special hairiness eliminating device is a hot point of the current ring spinning technology research. The current novel ring spinning technology represents a compact spinning technology, such as the invention patent of Device for spinning, condensing and transmitting area of fibers during spinning operation, which is disclosed by the intellectual property office of the United states in 1984, 12-18, patent No. US 4488397; the invention patent "Device for condensing a draft fiber strand", published by the intellectual property office of america at 2000, 6/13, patent No. 6073314; the invention patent "Device for condensing a draft fiber strand", published by the intellectual property office of america at 2000, 6/13, patent No. 6073314; the invention patent "Arrangement for condensing a draft fiber strand" published by the intellectual property office of the united states at 2000, 7, 4, patent No. 6082089; the invention patent "Transport belt for transporting a fiber strand to belt condensed" disclosed by the intellectual property office of the united states on day 1, month 9, 2001, patent No. US6170126B 1; the United states intellectual Property office 2001, 7, 24, patent number US 6263656B 1; the invention patent "Apparatus for condensing a draft strand" published by the intellectual property office 2001, 8, 14, U.S. Pat. No. US 6272834B 1; the invention patent "Condensing zone for a spinning machine" disclosed in 29.5.2001 of the intellectual property office of the United states, patent number US 6237317B 1. The core principle of the compact spinning technical patent publication is a needle ring spinning process, flat ribbon fiber strands are gathered to eliminate a spinning triangular space, the adhesion cohesion acting force between edge fibers and a twisting strand main body is increased, the control on the edge fibers of the fiber strands is enhanced, the exposure and escape of fiber head ends in the spinning process are effectively reduced, yarn hairiness and fiber loss are reduced, and the generation of flying is inhibited. However, compact spinning eliminates a spinning triangular space, internal and external transfer of fibers in a yarn body is insufficient, and the arrangement of the internal fibers is too straight and compact, so that the rigidity of the yarn is too high, and the softness is seriously deteriorated; particularly, through the compact spinning technology of airflow aggregation, additional negative pressure suction equipment needs to be arranged, the energy consumption is greatly increased, the installation, operation and maintenance costs of the compact spinning technology are high, the compact spinning technology becomes noble spinning, and the new principle of energy conservation, consumption reduction and low-carbon production is violated.
The special hairiness reducing device used at present is in the form of air jet, which is installed between the front roller and the yarn guide hook, and the formed hairiness is attached to the surface of the yarn by the action of extra rotary air flow, such as the invention patent "method and apparatus yarn guide" disclosed by the intellectual property office of the united states in 1979, 4-10, patent No. 41481779, the invention patent "method and apparatus for modifying yarn guide" disclosed by the intellectual property office of the united states in 1989, 8-22, 5263311. The main difference of these patents is that the fiber stress direction on the surface of the yarn is different due to the difference of the air jet devices, so that different winding effects are generated, and the yarn hairiness elimination effect is different. However, because these devices can only be installed behind the twisting triangle (because the fibers in the twisting triangle are basically in loose fiber shape, the jetted air flow can cause the fiber movement to be disordered and break), the air flow blowing objects are yarns and the hairs on the surfaces of the yarns, and the air flow flowing effects of the blowing objects are different, so that the hairs are left on the surfaces of the yarns in the forms of simple attachment and loose winding, and in the subsequent process (such as winding) processing, a machine part rubs and pulls out the fibers on the surface layer structure of the yarns, the loose attachment and the wound hairs are revealed again, and the effect of really eliminating the hairs cannot be achieved; the hair feather wrapping forms processed by the special hair feather reducing devices are mostly disordered wrapping forms, so that yarn nubs and neps are increased, and yarn evenness is deteriorated; in particular, these dedicated hairiness reduction devices do not solve the critical problem of the tendency of the flat ribbon-like edge fibers to escape forming fiber drops and fly.
The invention patent of "ironing spinning method for improving yarn performance" disclosed by the intellectual property office of china in 2007 in 07/11/2007, patent number 200610166509.9; the united states intellectual property office, 2009, 30, discloses the patent "Method and apparatus for producing high quality yarn on a ring-spinning machine", patent publication No. 7552580B 2. Both of these applications provide a method of ironing and spinning that can heat the fibers in the spinning triangle to improve the quality of the resultant yarn. However, the ironing device related to the method only limits to reduce the fiber modulus to improve the performance of easy torsion and bending of the fiber and improve the yarn finish, and can not solve the key problems that yarn faults and evenness are deteriorated due to disordered wrapping hairiness, and fiber at the flat ribbon edge is easy to escape to form fiber falling and flying. Also, the ironing device still brings extra energy consumption problem, and the effect of ironing and spinning some fibers with poor heat sensitivity (such as wool fibers) is poor, and the quality of the finished yarn cannot be improved.
