Description
Technical field
The invention belongs to technical field of textile equipment, be specifically related to a kind of air injection air vortex spinning apparatus vortex tube.
Background technology
Air vortex spinning utilizes fixed vortex spinning spool, replaces the rotor of high speed rotary to carry out a kind of spinning method spinned.In a sense, air vortex spinning is only open-end spinning truly.Ribbon is fed by feed roll motor, becomes filament through licker-in release, by means of the effect of air-flow, from cotton delivery pipe at a high speed feeding vortex tube.Vortex tube is made up of core pipe and outer tube two parts.Outer tube has three tangential air inlets, lower end is connected with air blast, and blower fan is extracting air from pipe constantly, and the air of outside enters in vortex tube along air inlet, produces gyrate air-flow.When rotating air-flow upwards and arriving core pipe, the fiber entered with cotton delivery pipe converges, and form a cohesion fibrous ring along vortex tube inwall, stably around vortex tube axis, high speed rotary, twists resultant yarn by fiber.Yarn is continuously drawn by extraction roller and is wound into bobbin from thread guide eyelet.
The topmost feature of air vortex spinning is omitted the spinning parts of high speed rotary.Break away from the rotator inertia problem that twisting parts at a high speed cause and bearing load problem (cup as open-end spinning) owing to adopting air-flow twisting, also had the air ring because spinning is formed and increase the problem (as ring spinning) of spinning tension.
As the vortex tube of air injection air vortex spinning key problem in technology technology, in whole spinning process, mainly utilize the yarn after high speed rotary air-flow counter extensioin to carry out twisting and resultant yarn, the parameters of injector holes of vortex tube is very large on spinning impact, its difference can cause the great changes of air-flow, therefore directly affects the motion state of fiber, and then directly have influence on yarn quality and the energy consumption loss of whole device, therefore, a kind of yarn quality is high, and the little vortex tube of energy consumption loss just seems particularly important for whole spinning apparatus.
Summary of the invention
Object of the present invention is exactly will provide a kind of can improve air-flow twisting efficiency in existing air injection air vortex spinning apparatus and spinning speed further, promote yarn quality, jet-impingement number of perforations can be reduced, to save the air injection air vortex spinning apparatus vortex tube of air consumption simultaneously.
The present invention is achieved through the following technical solutions:
A kind of air injection air vortex spinning apparatus vortex tube, be made up of the hollow cavity 2 of body 1, body 1 inside and air-flow spray-hole 4, wherein the hollow cavity 2 in exit, jet-impingement hole 4 is interior forms minor air cell 3, it is characterized in that: described jet-impingement hole 4 diameter is 0.5mm.
Described jet-impingement hole 4 is tangent with hollow cavity 2 inwall.
Described jet-impingement hole 4 tilt angle alpha is 45 °.
Evenly distributed on described body 1 have four jet-impingement holes 4.
Compared with prior art, beneficial effect of the present invention is:
Provided by the invention by body 1, hollow cavity 2, the vortex tube that minor air cell 3 and air-flow spray-hole 4 form, drafting system is accepted in vortex tube upper end, jet-impingement hole 4 is connected with high-pressure air source, vortex tube lower end is connected with impurities removal negative pressure cavity, compressed air stream forms enough large negative pressure in porch, jet-impingement hole 4, the parallel fibers bundle exported through front roller is inhaled into, make the high-velocity jets ejected from jet-impingement hole 4 directly can act on inversion subsides volt and draw the tail end fiber on yarn cone entrance portion perimeter wall, the speed of gyration of tail end fiber can be significantly improved, improve the twisting efficiency of swirling eddy.Compared with prior art, adopt the spinning speed of the air injection air vortex spinning apparatus of this device and yarn quality to promote further, and the number in jet-impingement hole suitably can reduce, save air consumption.
Beneficial effect of the present invention is: the diameter when jet-impingement hole 4 is 0.5mm, and quantity is 4, and when tilt angle alpha is 45 °, single end strength is large, and yarn quality is good and energy consumption is minimum.
Accompanying drawing explanation

Fig. 2 is plan structure schematic diagram of the present invention.
In figure: body 1, hollow cavity 2, minor air cell 3, jet-impingement hole 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
A kind of air injection air vortex spinning apparatus vortex tube, is made up of the hollow cavity 2 of body 1, body 1 inside and air-flow spray-hole 4.
As shown in Figure 1, wherein the hollow cavity 2 in exit, jet-impingement hole 4 is interior forms minor air cell 3, evenly distributed on body 1 have four jet-impingement holes 4, jet-impingement hole 4 diameter is 0.5mm, and jet-impingement hole 4 is tangent with hollow cavity 2 inwall, the tilt angle alpha in jet-impingement hole 4 is 45 °.
The present invention is when specifically using, drafting system is accepted in vortex tube upper end, jet-impingement hole 4 is connected with high-pressure air source, vortex tube lower end is connected with impurities removal negative pressure cavity, compressed air stream forms enough large negative pressure in porch, jet-impingement hole 4, the parallel fibers bundle exported through front roller is inhaled into, make the high-velocity jets ejected from jet-impingement hole 4 directly can act on inversion subsides volt and draw the tail end fiber on yarn cone entrance portion perimeter wall, the speed of gyration of tail end fiber can be significantly improved, improve the twisting efficiency of swirling eddy.
Because the diameter when jet-impingement hole 4 is 0.6mm, quantity is 4, and when tilt angle alpha is 45 °, single end strength is maximum; Diameter when jet-impingement hole 4 is 0.5mm, and quantity is 4, and when tilt angle alpha is 45 °, single end strength takes second place; Diameter when jet-impingement hole 4 is 0.6mm, quantity is 5, when tilt angle alpha is 45 °, single end strength is also better, and the energy consumption size of three is contrary, therefore, diameter when jet-impingement hole 4 is 0.5mm, and quantity is 4, when tilt angle alpha is 45 °, single end strength is large, and yarn quality is good and energy consumption is minimum.
