Description
Technical field
The present invention relates to the improvement of jet loom for drawing weft yarn mechanism, 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.Its special filling insertion way, makes it possess the feature of 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, promote the performance of air-jet loom in efficient, energy-conservation, varietal adaptation etc. further.
But the filling insertion way of air-jet loom also inevitably brings some problems, be wherein apparent that the untwisting phenomenon of weft yarn in wefting insertion process the most.In air-jet loom air-jet weft insertion process, weft yarn is in no-console condition, because weft yarn is not 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 be eliminated, and when weaving broad fabrics, this untwisting phenomenon is more obvious.
Untwisting phenomenon can have an impact to actual production.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, for the warp thread at weft yarn tail end position, often need to keep menopause tablet not fall by devices such as some little additional pads, maintain carrying out smoothly of weaving process with this, so, although there will not be the mistakenly stop of loom, but, the warp end break that part should detect can be missed, affect fabric unit effect.
Weft Detwisting phenomenon also can have an impact to the style forming fabric.As everyone knows, the size of the twist is omnibearing for the impact of yam physical mechanical performance, can have influence on the factors such as the 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 current today more and more paying attention to 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 adjustment dyeing, can not fundamentally solve.
In order to the untwisting phenomenon that weakens jet loom for drawing weft yarn process is on the impact of actual production and final products, applicant have developed a kind of two-way wefting insertion air-jet loom, its wefting insertion process is different from common air-jet loom, to be hocketed wefting insertion by the left and right sides, balance the twist of both sides yarn like this, 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, when 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, pilot jet will be there is too much, the problems such as feeding pneumatic is long, like this, in narrow space, how more reasonably to arrange, install that the air-channel system of pilot jet has just become is the difficult point of two-way wefting insertion air-jet loom.
