Description
Technical field
The utility model relates to the improvement of jet loom for drawing weft yarn mechanism, and specifically a kind of air-channel system of two-way wefting insertion auxiliary nozzle used in jet loom, belongs to textile machine equipment technical field.
Background technology
Air-jet loom adopts jet-stream wind as carrier, and by the frictional force effect between air-flow and yarn, weft traction passes through shed open, forms fabric.The filling insertion way that it is special, makes its feature that possesses high-speed and high-efficiency, takes into account wider varietal adaptation simultaneously, is the important directions of current shuttleless loom development.In recent years, no matter be external production firm or domestic loom manufacturing enterprise, all in the research and development of air-jet loom, drop into a large amount of manpower and materials, at a high speed, the aspect such as efficient, energy-conservation, varietal adaptation further promotes the performance of air-jet loom.
Yet the filling insertion way of air-jet loom has also inevitably brought some problems, be wherein apparent that the most the untwisting phenomenon of weft yarn in wefting insertion process.In air-jet loom air-jet weft insertion process, weft yarn, in no-console condition, because weft yarn does not pass through sizing technique, makes weft yarn in flight wefting insertion process, occur the phenomenon of untwisting.Although the high speed process of air-jet loom makes the time of weft yarn under the state of this uncontrolled flight shorter and shorter, this untwisting phenomenon can not eliminated, and while weaving broad fabrics, this untwisting phenomenon is more obvious.
Untwisting phenomenon exerts an influence to actual production meeting.Main manifestations is that the rigidity of loom left and right sides weft yarn is different, and tail end yarn twist is lower, and rigidity is lower, and making corresponding warp thread flexing less, tension force is less than normal, along with the carrying out of weaving process, this tension force situation less than normal can add up, and causes opening unclear, warp-wise mistakenly stop etc.Therefore, in actual weaving process, warp thread for weft yarn tail end position, often need to keep menopause tablet not fall by devices such as some little additional pads, with this, maintain carrying out smoothly of weaving process, so, although there will not be the mistakenly stop of loom, but, can miss the warp end break that part should detect, affect fabric whole structure.
Weft Detwisting phenomenon also can exert an influence to forming the style of fabric.As everyone knows, the size of the twist is omnibearing for the impact of yarn physical and mechanical properties, can have influence on the factors such as dye-uptake in yarn dyeing process especially.Adopt the openpore fabric of air-jet loom weaving, in dyeing course, easily produce the aberration between the left and right sides.In today of more and more paying attention at present product appearance quality, the aberration between this left and right sides becomes the great difficult problem of air-jet loom weaving, often can only be made up by adjusting dyeing, can not fundamentally solve.
For the impact on actual production and final products of the untwisting phenomenon that weakens jet loom for drawing weft yarn process, applicant has researched and developed a kind of two-way wefting insertion air-jet loom, its wefting insertion process is different from common air-jet loom, by the left and right sides wefting insertion that hockets, like this balance the twist of both sides yarns, fundamentally solve the problems referred to above that untwisting brings.
In two-way wefting insertion process, the weft insertion device of air-jet loom all needs to pass through shed open from both sides weft traction, and the critical piece of weft insertion device comprises main burner, auxiliary main burner and profiled steel reed, and wherein special-shaped reed can directly be converted from common air-jet loom.Owing to being two-way wefting insertion, in the situation that various process parameters is constant, the quantity of pilot jet will be 2 times of common one-sided wefting insertion air-jet loom.If simply install additional on common one-sided wefting insertion air-jet loom, to exist pilot jet too much, the problems such as air feed gas circuit is long, it is the difficult point of two-way wefting insertion air-jet loom that air-channel system like this, how more reasonably to arrange, install pilot jet in narrow space has just become.
