Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, a kind of air jet spinning air vortex spinning device, comprises and is hinged on spinning machine and is provided with the upper bracket of resultant yarn conjunction 6 and be provided with the lower carriage 7 of lower resultant yarn conjunction 8 with it.Wherein, upper bracket is connected with negative pressure scavenge unit, and lower carriage 7 is connected with cylinder 3.
Upper bracket comprises fixing upper bracket and movable upper bracket, movable upper bracket and rotating shaft hinged, fixing upper bracket is fixedly connected with by screw with movable upper bracket, upper bracket is divided into two parts to comprise fixing upper bracket 4 and movable upper bracket 5, fixing upper bracket 4 and lower carriage 7 are by locating hole hinge in rotating shaft 2, and rotating shaft 2 is connected in fixed support 1.Alignment pin 9 and screw I10 are connected in fixing upper bracket 4 from spinning machine front by movable upper bracket 5, and upper resultant yarn conjunction 6 is connected in movable upper bracket 5 centre bore by screw II11.This architectural feature of upper bracket, when spinning machine normally works, when each roller shaft High Rotation Speed, accessiblely can pull down movable upper bracket, safeguards the superincumbent cotton-conveying pipe of installation and top nozzle.
As shown in Figure 3 and Figure 4, upper resultant yarn conjunction 6 comprises the upper resultant yarn being connected with compressed air 607 and connects cover plate and from top to bottom through cotton-conveying pipe 605 and the top nozzle 603 being arranged on upper resultant yarn and being connected cover plate central successively.Wherein, upper resultant yarn connects cover plate and comprises resultant yarn connecting plate 601 and upper resultant yarn gas lid 606.Upper resultant yarn gas lid 606 plane and upper resultant yarn connecting plate 601 plane fit, upper resultant yarn gas lid 606, uses screw IV13, by the cotton-conveying pipe 605 with sealing ring 604, be fastened on upper resultant yarn connecting plate 601 with the top nozzle 603 with sealing ring 602, resultant yarn conjunction 6 on composition.
As shown in Figure 4 and Figure 5, cotton-conveying pipe 605 comprises steel body 60501, cotton transport block 60502 and draw point 60503.Cotton transport block 60502 is irregular half screw cone, smooth surface, tapered portion and the bonding cooperation of steel body 60501 inner conical surface, forms narrow fiber channel after coordinating.Draw point 60503 adopts large conical surface form, the large conical surface of draw point 60503 head and the seamless transition of cotton transport block 60502, ensure that cotton fiber can fully stretch in conveying transfer process, filament is decomposed into more in vortex cavity, filament is more easily twisted looping outside heart yarn, forms the Air Vortex Spun Yarn that the twist is high, powerful high, simultaneously, the negative pressure that short flannel part in fiber is connected upper bracket is removed, and the bar solid carbon dioxide substantially increasing yarn is put down.
As shown in Figure 3 and Figure 4, top nozzle 603 is revolving body ceramic member, and core is smooth step vortex cavity, and top nozzle 603 is provided with the pore through with compressed air, forms angle between the direction that pore is jet and the center line of top nozzle.Pore can be set to 5.
Because the stepped hole of upper resultant yarn gas lid 606 mid portion communicates with outside, outside is connected to compressed air 607.Due to the effect of two place's sealing rings, after compressed air 607 enters upper resultant yarn gas lid 606, can only enter in fiber channel by 5 place's pores of top nozzle 603, form counterclockwise and downward high-speed eddy.
As shown in Figure 2 and Figure 6, lower resultant yarn conjunction 8 comprises the lower resultant yarn being connected with compressed air 808 and connects cover plate and be arranged on lower resultant yarn be connected the spindle 804 of cover plate central, lower nozzle 803 and yarn-guide mouth 807 with through successively from top to bottom.Wherein, the position of spindle 804 is corresponding with draw point 60503 head position.Lower resultant yarn connects cover plate and comprises lower resultant yarn adapter sleeve 801 and lower resultant yarn connecting plate 802.Lower resultant yarn adapter sleeve 801 and lower resultant yarn connecting plate 802 screw III12 are connected.Spindle 804 and lower nozzle 803 are fixed on inside.Lower nozzle 803 is assemblied in lower resultant yarn adapter sleeve 801.Spindle 804 and lower nozzle 803 are chained together, and there is the fiber channel communicated at center.Lower nozzle 803 is provided with the pore through with compressed air 808, forms angle between the center line of the direction that pore is jet and lower nozzle.Pore can be set to 5.The seam crossing being connected cover plate at lower nozzle 803 with lower resultant yarn is separately installed with sealing ring 805 and sealing ring 806 up and down.Due to the effect of lower nozzle upper-lower seal circle, compressed air can only enter the fiber channel at center by 5 place's pores of lower nozzle, form clockwise high-speed eddy, attracts yarn enter and twist further, then from yarn-guide mouth ejection spinning organ.
As shown in Figure 3 and Figure 6, lower resultant yarn connecting plate 802 in lower resultant yarn conjunction 8 is provided with 3 place's annular slots of circumference uniform distribution, the 3 place's lower carriage connecting axles 14 arranged with lower carriage 7 centre bore surrounding are fixedly connected with, and under 3 places, resultant yarn connecting axle 14 place is provided with stage clip 15.And coordinate with movable upper bracket 5 position contacted at lower resultant yarn connecting plate 802, be set to Rouno Cormer Pregrinding Wheel transition especially.When cylinder 3 promote lower carriage 7 close time, lower resultant yarn connecting plate 802 under the effect of stage clip 15, easy centering center.In addition, the Rouno Cormer Pregrinding Wheel that lower resultant yarn connecting plate 802 is arranged especially, increases the reliability that lower resultant yarn connecting plate 802 slips into movable upper bracket 5 mating surface, ensure that the sealing of vortex cavity is reliable, steady air current, thus can obtain high-quality yarn.
The present invention is when spinning, upper bracket and lower carriage 7 are closed under the promotion of cylinder 3, compressed air 607 enters fiber channel by top nozzle 603 small taper hole, the negative pressure formed brings the yarn after drawing-off into cotton-conveying pipe 605, spindle 804 aperture is imported into as heart yarn after arriving draw point 60503 head, fiber afterbody has departed from the jaw of roller, lodging is at spindle 804 head, between the small gaps that top nozzle 603 and spindle 804 are formed, under top nozzle 603 counterclockwise high-speed eddy effect, fibre compact looping is outside heart yarn, form yarn, the compressed air 808 entering lower nozzle 803 forms clockwise high-speed eddy, center forms negative pressure, yarn is attracted to enter lower nozzle and splice further, finally by outside yarn-guide mouth ejection spinning organ.
