Description
Technical field
The utility model relates to a kind of spiral suction yarn device, relates to the pilot jet of air-jet loom.
Background technology
The Weft insertion method of air-jet loom uses compressed air stream weft traction, and weft tapes is crossed shed open.The principle of pneumatic picking just applied for patent by Brooks as far back as 1914, but until the Second Committee ITMA of nineteen fifty-five has just put on display model machine, its reed width also only has 44cm.The real maturation of air-jet loom is after these two more than ten years.Why through the so long time, because the wefting insertion medium of air-jet loom is air, and how to control the air-flow of easily diffusion, and effectively weft yarn is drawn to suitable position, meet the requirement of wefting insertion, be an extremely scabrous technical problem, until a collection of patent progressively enters the practical stage, this difficult problem is resolved.The nearest more than ten years, along with the extensive use on air-jet loom of electronic technology, microcomputer technology, its mechanism section simplifies greatly, and processing performance is even more ideal, in fabric quality, productivity ratio, had significant progress.Air-jet loom has become a kind of loom with fastest developing speed.In the evolution of air-jet loom, single injector wefting insertion and the large type of major-minor nozzle relay wefting insertion two are defined.Preventing in Diffusion of gas stream, also there are two kinds of modes: one is confuser mode, and another kind is Profiled Reed mode.Three kinds of wefting insertion patterns of air-jet loom are defined by the various combination of filling insertion way and air-flow diffusion way.
Existing pilot jet is in the process of wefting insertion, and the moment that weft yarn arrives is stretching, 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.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problems referred to above, provides a kind of spiral suction yarn device that weft yarn can be sucked.
The utility model solves the technical scheme that its technical problem adopts:
A kind of spiral suction yarn device, comprise nozzle body and nozzle carrier, described nozzle body is dismountable to be arranged in nozzle carrier, and described nozzle body is spirality, and the shower nozzle of described nozzle body has scarf, and described scarf is provided with spray orifice.
Preferably, described spray orifice comprises multiple side spray holes that the center of orifices that is arranged on scarf center and described center of orifices surrounding are evenly 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 holding screw and bolt.
Preferably, the diameter of described spray orifice is 1-2mm.
Preferably, the diameter of described center of orifices is greater than described side spray bore dia.
The beneficial effects of the utility model are: in the utility model, nozzle body is arranged to spirality, weft yarn can by the spiral nozzle body of the utility model inspiration in the moment of stretching rebound, because be arranged to spirality, so length is enough long in nozzle body, enough by weft yarn inspiration, and then spray, just do not pressurize, total gas pressure is reduced, reduce total gas consumption and technological requirement reduction, wefting insertion better effects if.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the side view of the utility model embodiment;
Fig. 2 be the utility model embodiment install and use side view.
Mark in figure: 1-nozzle body, 2-nozzle carrier, 3-holding screw, 4-bolt, the special-shaped reed base of 5-, the special-shaped reed of 6-, 7-wefting insertion opening.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
One described in the utility model spiral suction yarn device as shown in Figure 1, comprise nozzle body 1 and nozzle carrier 2, described nozzle body 1 is dismountable to be arranged in nozzle carrier 2, described nozzle body 1 is spirality, the shower nozzle of described nozzle body 1 has scarf, described scarf is provided with spray orifice, in normal wefting insertion process, adopting main burner existing more, the mode that pilot jet and different in nature reed combine realizes wefting insertion, existing pilot jet is in the process of wefting insertion, the moment that weft yarn arrives is stretching, need rebound, at this moment need the meeting of weft yarn top pilot jet aerating, the total gas pressure of use can be caused to raise, waste gas, and in the utility model, nozzle body 1 is arranged to spirality, weft yarn can by the spiral nozzle body 1 of the utility model inspiration in the moment of stretching rebound, because be arranged to spirality, so length is enough long in nozzle body 1, enough by weft yarn inspiration, and then spray, just do not pressurize, total gas pressure is reduced, reduce total gas consumption and technological requirement reduction, wefting insertion better effects if.
In preferred embodiments, described spray orifice comprises 12 side spray holes that the center of orifices that is arranged on scarf center and described center of orifices surrounding are evenly arranged ringwise, described 12 side nozzles are evenly arranged on around central nozzle, arrange 12 side spray holes to arrange for preferred, can also other numbers be set as required.
In preferred embodiments, the spiral number of turns of described nozzle body 1 is 1 circle or 2 circles, and it is the most basic selection that the spiral number of turns is set to 1 circle, meets the length of weft yarn inspiration, is set to 2 circles and selects for preferred.
In preferred embodiments, the relative two sides of described nozzle carrier 2 are respectively arranged with holding screw 3 and bolt 4, described holding screw 3 is for being fixed in nozzle carrier 2 by nozzle body 1, described bolt 4 is for being fixed on special-shaped reed 6 base 5 by nozzle carrier 2, as shown in Figure 2, the scarf of the front end of nozzle body 1 described in figure aims at the wefting insertion opening 7 of different in nature reed.
In preferred embodiments, the diameter of described spray orifice is 1-2mm, and this is chosen as preferred selection, can also select as required.
In preferred embodiments, the diameter of described center of orifices is greater than described side spray bore dia, compressed air stream forms circular jet when center of orifices penetrates, the feature that it has " injection bunchy ", the air velocity of nozzle ejection is 100 ~ 200m/s, when they are once contact surrounding air, micelle in jet boundary just will mix with adjacent still air, consequently a part of momentum of oneself is passed to ambient air by jet, the originally static air of part is driven by jet travel forward, produce from the gas of side spray hole ejection gas and described center of orifices the effect gathering bunchy in the utility model, meet jet composition principle, more technical than single hole jet-stream wind good, be not easy diffusion and jet length is far away.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
