Description
Technical field
The present invention relates to a kind of spiral suction yarn device, relate to the pilot jet of air-jet loom.
Background technology
The Weft insertion method of air-jet loom is to use compressed air stream weft traction, and weft tapes is crossed shed open.Pneumatic picking
Principle just Brooks has been applied for patent as far back as 1914, but until on the Second Committee ITMA of nineteen fifty-five
Just having put on display model machine, its reed width also only has 44cm.Air-jet loom really maturation is after these more than 20 years.
It why through the time so grown, is because that the wefting insertion medium of air-jet loom is air, and how to control appearance
The easily air-flow of diffusion, and effectively weft yarn is drawn to suitable position, meet the requirement of wefting insertion, be one
Extremely difficult solving the technical problem that, until a collection of patent steps into the practical stage, this difficult problem has been resolved.
The nearest more than ten years, with the extensive application on air-jet loom of electronic technology, microcomputer technology, its mechanism section
Being greatly simplified, processing performance is even more ideal, has had significant progress in terms of fabric quality, productivity ratio.Spray
Gas loom has become a kind of loom with fastest developing speed.In the evolution of air-jet loom, define single spraying
Mouth wefting insertion and the big type of major-minor nozzle relay wefting insertion two.Also there is a two ways in terms of preventing Diffusion of gas stream: one
Planting is confuser mode, and another kind is Profiled Reed mode.By different groups of filling insertion way and air-flow diffusion way
Close the three kinds of wefting insertion patterns defining air-jet loom.
Existing pilot jet is during wefting insertion, and the moment that weft yarn reaches stretches, and needs rebound, at this moment
Need the meeting of weft yarn top to pilot jet aerating, the total gas pressure of use can be caused to raise, waste gas.
Content of the invention
The technical problem to be solved in the present invention is: for overcoming the problems referred to above, provides and a kind of can suck weft yarn
Spiral suction yarn device.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of spiral suction yarn device, including nozzle body and nozzle carrier, the dismountable installation of described nozzle body
In nozzle carrier, described nozzle body is spirality, and the shower nozzle of described nozzle body has a scarf, described tiltedly
It is provided with spray orifice on tangent plane.
Preferably, described spray orifice includes being arranged on scarf center center of orifices and described center of orifices surrounding
The multiple side spray holes being uniformly arranged ringwise.
Preferably, the spiral number of turns of described nozzle body is 1 circle or 2 circles.
Preferably, the relative two sides of described nozzle carrier are respectively arranged with fastening screw and bolt.
Preferably, a diameter of 1-2mm of described spray orifice.
Preferably, the diameter of described center of orifices is more than described side spray bore dia.
The invention has the beneficial effects as follows: in the present invention, nozzle body is arranged to spirality, and weft yarn is stretching
The moment of rebound can be by the spiral nozzle body of inspiration of the present invention, because being arranged to spirality, so spray
In mouth main body, length is enough long, enough by weft yarn inspiration, then sprays again, just must not pressurize so that total gas pressure
Reducing, reducing total gas consumption and technological requirement reduces, wefting insertion effect is more preferable.
Brief description
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the side view of one embodiment of the invention；
Fig. 2 be one embodiment of the invention install and use side view.
Marking in figure: 1-nozzle body, 2-nozzle carrier, 3-fastens screw, 4-bolt, the special-shaped reed of 5-
Base, the special-shaped reed of 6-, 7-wefting insertion opening.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification,
The basic structure of the present invention is described only in a schematic way, and therefore it only shows the composition relevant with the present invention.
One of the present invention as shown in Figure 1 spirally inhales yarn device, including nozzle body 1 and nozzle carrier 2,
Described nozzle body 1 is detachably arranged in nozzle carrier 2, and described nozzle body 1 is spirality, described
The shower nozzle of nozzle body 1 has scarf, and described scarf is provided with spray orifice, during normal wefting insertion,
The existing mode using main burner, pilot jet and opposite sex reed to combine realizes wefting insertion, existing pilot jet more
During wefting insertion, the moment that weft yarn reaches stretches, and needs rebound, at this moment needs to pilot jet aerating
By the meeting of weft yarn top, the total gas pressure of use can be caused to raise, waste gas, and in the present invention, by nozzle body 1
Be arranged to spirality, weft yarn stretch rebound moment can by the spiral nozzle body of inspiration of the present invention 1,
Because being arranged to spirality, so length is enough long in nozzle body 1, enough by weft yarn inspiration, then spray again
Go out, just must not pressurize so that total gas pressure reduces, reduce total gas consumption and technological requirement reduces, wefting insertion
Effect is more preferable.
In preferred embodiments, described spray orifice includes being arranged on the center of orifices at scarf center and described
12 side spray holes that center of orifices surrounding is uniformly arranged ringwise, during described 12 side nozzles are uniformly arranged on
Around heart nozzle, 12 side spray holes are set for being preferable to provide, other numbers can also be arranged as required to.
In preferred embodiments, the spiral number of turns of described nozzle body 1 is 1 circle or 2 circles, spiral coil
It is most basic selection that number is set to 1 circle, meets the length of weft yarn inspiration, and it is preferred for being set to 2 circles
Select.
In preferred embodiments, the relative two sides of described nozzle carrier 2 are respectively arranged with fastening screw 3
With bolt 4, described fastening screw 3 is used for being fixed in nozzle carrier 2 by nozzle body 1, described positioning
Bolt 4 is used for nozzle carrier 2 is fixed on special-shaped reed 6 base 5, as in figure 2 it is shown, nozzle described in figure
The wefting insertion opening 7 of the scarf alignment opposite sex reed of main body 1 front end.
In preferred embodiments, a diameter of 1-2mm of described spray orifice, this is chosen as preferably selecting, also
Can select as required.
In preferred embodiments, the diameter of described center of orifices is more than described side spray bore dia, compressed gas
Stream forms circular jet when penetrating from center of orifices, and it has the feature of " injection bunchy ", nozzle ejection
Air velocity is 100～200m/s, when they are once contact surrounding air, and the micelle in jet boundary
Just to mix with adjacent still air, its result is that a part of momentum of oneself is passed to around by jet
Air, make the originally static air of part be driven by jet and travel forward, from the ejection of side spray hole in the present invention
The gas of gas and described center of orifices produces gathers bundles of effect, meets jet composition principle, compares single hole
Jet-stream wind is technical good, it is not easy to diffusion and jet length are remote.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, related work
Personnel can carry out various change and modification completely in the range of without departing from this invention technological thought.
The content that the technical scope of this invention is not limited on specification, it is necessary to according to right
Determine its technical scope.
