Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is the close-up schematic view of the straight double twisting of the present invention general yarn road assembly.
In figure: spindle blade 1, the centre bore 11 on spindle blade top, the centre bore 12 of spindle blade bottom, straight double twisting general yarn road assembly 2, top bending through hole 21, bottom bending through hole 22, converge jut 23, common-use tunnel 24, nozzle 3, yarn storage dish 4, suction airstream f, the outer yarn F1 of straight sth. made by twisting, double twisting feeding yarn F2, suction airstream f.
Detailed description of the invention
As in Fig. 1, a kind of straight sth. made by twisting and the general pneumatic spinning-in system of double twisting, comprise spindle blade 1, bottom and the top of the centre bore 11 on spindle blade top bend through hole 21 and are communicated with, top and the bottom of the centre bore 12 of spindle blade bottom bend through hole 22 and are communicated with, described top bends through hole 21 and described bottom bending through hole 22 converges formation common-use tunnel 24, and the meet formation of described top bending through hole 21 and described bottom bending through hole 22 converges jut 23.Structure thus, when passing into compressed air from the centre bore 12 of spindle blade bottom, in common-use tunnel 24, suction airstream f is produced by bernoulli principle, form common-use tunnel 24 because top bending through hole 21 and bottom bending through hole 22 converge, then all can be sucked air-flow f from the yarn of the centre bore 11 on spindle blade top and the centre bore 12 of spindle blade bottom and guide and pass from common-use tunnel 24.
As in Fig. 2, the described distance converging jut 23 distance between two tips spindle blade 1 axis is greater than the radius of spindle blade centre bore.Structure thus, guarantees to form reliable suction airstream f, avoids compressed air to fall to rush the centre bore 12 entering into spindle blade bottom.
In the scheme optimized, described top bending through hole 21 and bottom bending through hole 22 are minimum at the diameter of kink.Structure thus, guarantees that the air-flow velocity at this place is maximum, thus guarantees that yarn is quickly through this kink.
Described top bending through hole 21, bottom bending through hole 22 and common-use tunnel 24 form " Y " shape passage jointly, and integralization is positioned at straight double twisting general yarn road assembly 2.
Described straight double twisting general yarn road assembly 2 is positioned at yarn storage dish 4, and top bending through hole 21 and bottom bend through hole 22 access aperture axis and yarn storage dish 4 dead in line.
Centre bore 12 lower end of described spindle blade bottom is provided with the nozzle 3 for being connected with compressed air.
As in Fig. 1, a kind ofly adopt above-mentioned device to carry out the pneumatic threading method of straight double twisting, comprise the following steps:
The bottom of the centre bore 11 on spindle blade 1 spindle blade top and top are bent through hole 21 be communicated with, top and the bottom of the centre bore 12 of spindle blade bottom bend through hole 22 and are communicated with, described top bending through hole 21 and described bottom bending through hole 22 merge into common-use tunnel 24, and top bending through hole 21 and described bottom bending through hole 22 formation converge jut 23;
The described distance converging jut 23 distance between two tips spindle blade 1 axis is made to be greater than the radius of spindle blade centre bore;
Compressed air is passed at nozzle 3, then the yarn of the feeding centre bore 11 on spindle blade top and the centre bore 12 of spindle blade bottom can lead to yarn storage dish 4 from the common-use tunnel 24 of straight double twisting general yarn road assembly 2 by interior suction airstream f, the described suction airstream f of producing of the common-use tunnel 24 of straight double twisting general yarn road assembly 2; Adopt the method, no matter for directly twisting with the fingers or for double twisting, all can producing suction airstream f at common-use tunnel 24 place, for guiding yarn after passing into compressed air.
Be specially, when described spindle is used as directly to twist with the fingers, compressed air is carried to nozzle 3, the outer yarn F1 of straight sth. made by twisting coming from creel enters the centre bore 12 of spindle blade bottom at nozzle 3 place with compressed air, and then the bottom that the straight double twisting general yarn road assembly 2 that leads under the effect of suction airstream f is in the duct connected with the centre bore 12 of the spindle blade bottom of spindle blade hollow shaft bends through hole 22, outwards lead to outside yarn storage dish 4 along the common-use tunnel 24 on straight double twisting general yarn road assembly 2 again, realize straight pneumatic repiece of twisting with the fingers outer yarn.
When described spindle is used as double twisting, compressed air is carried to nozzle 3, suction airstream f is defined in centre bore 12 in the spindle blade bottom of spindle blade hollow shaft and the bottom bending through hole 22 in the straight double twisting general yarn road assembly 2 be attached thereto and common-use tunnel 24, through hole 22 is bent with bottom and common-use tunnel 24 communicates with each other due to the top bending through hole 21 in straight double twisting general yarn road assembly 2, therefore, to bend the suction airstream f direction produced because of suction function in the centre bore 11 on the spindle blade top of the spindle blade hollow shaft that through hole 21 is connected downward with top, in this case, the double twisting feeding yarn F2 come from spindle bends through hole 21 along centre bore 11 to the top on spindle blade top under the effect of suction airstream f, outside through common-use tunnel 24 again, lead to outside yarn storage dish 4, realize the pneumatic repiece of double twisting feeding yarn F2.
The straight sth. made by twisting pneumatic repiece general with double twisting is realized by above-mentioned steps.
