Abstract
The invention discloses a double-swing main jet wefting insertion mechanism of a jet loom, comprising a fist-level main jet and a second-level main jet. The double-swing main jet wefting insertion mechanism of a jet loom is characterized in that the first-level main jet and the second-level main jet are arranged on the same buckle seat and synchronously swing with the buckle seat, the first-level main jet is arranged in front of the second-level main jet, and the nozzle of the second-level main jet is aligned with the nozzle of the first-level main jet one by one. In the invention, the fist-level main jet performs the main dragging action on weft yarn, the second-level main jet is the supplement of the fist-level main jet, and the second-level main jet and the first-level main jet are arranged on the same buckle seat and synchronously swing, which not only can obtain large enough traction to provide enough time for the weft yarn to fly but also can cause the weft yarn to fly along a straight line so as to reduce unnecessary bending resistance, and thus the weft yarn can smoothly fly. The invention lowers gas consumption, and can better improve wefting insertion rate to obtain the effect of energy saving and high efficiency. Meanwhile, the invention can better adapt to the requirements of high speed and wide width of jet looms.
Description
Technical field
The present invention relates to a kind of air-jet loom, special relevant with the weft insertion device of air-jet loom.
Background technology
The air-jet loom of prior art is in weaving, and the main jet of weft insertion device partly adopts the one-level main jet to realize with the mode that the secondary main jet combines, i.e. one group of secondary main jet (auxiliary main jet) and one group of one-level main jet with the slay swing that is fixed on the frame.Because the secondary main jet is fixed; In the wefting insertion process; The nozzle of the secondary main jet that can not together swing with slay can lose the energy of Compressed Gas greatly, and then influences the woven latitude rate of going into, can not adapt to well air-jet loom at a high speed with wide cut aspect the needs that develop.
Summary of the invention
Task of the present invention is to solve the existing technological deficiency of weft insertion device main jet part of prior art air-jet loom, provides a kind of air-jet loom double pendulum to move the main jet weft insertion device.
Its technical solution is:
A kind of air-jet loom double pendulum moves the main jet weft insertion device; Comprise one-level main jet and secondary main jet; One-level main jet and secondary main jet are arranged on the same Button Block and with this Button Block to be swung synchronously; One-level main jet position is preceding, secondary main jet position after, the nozzle of secondary main jet aligns with the nozzle of one-level main jet one by one.
Button Block pin and back Button Block pin before above-mentioned Button Block is provided with, preceding Button Block pin is the oscillation center of Button Block with the axle center at Button Block pin place, back.
Above-mentioned one-level main jet and the nozzle that the secondary main jet respectively is provided with more than two, quantity is identical.
The present invention has following useful technique effect:
Among the present invention, the one-level main jet plays main draw to weft yarn, and the secondary main jet is that secondary main jet and one-level main jet are arranged on the same Button Block to the replenishing of one-level main jet; Swing synchronously can either reach enough big tractive force together, for the flight of weft yarn provides time enough; Can guarantee that again weft yarn along rectilinear flight, reduces unnecessary bending resistance, make weft yarn flight smooth and easy; Reduce air consumption, can be good at improving the wefting insertion rate, reach energy-conservation, ideal effect efficiently.The needs that can also adapt to simultaneously, air-jet loom development aspect high speed and wide cut well.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further:
Fig. 1 is the structural principle sketch map of one embodiment of the present invention.
Fig. 2 is the main TV structure sketch map of Fig. 1.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2, a kind of air-jet loom double pendulum moves the main jet weft insertion device, comprises one-level main jet 1 and secondary main jet 2; The one-level main jet is arranged on the Button Block 3, and it has two nozzles 101,102, and the secondary main jet also is arranged on the Button Block 3; It also has two nozzles 201,202, and above-mentioned one-level main jet 1 position is preceding, secondary main jet 2 positions after; The nozzle 201 of secondary main jet 2 aligns with the nozzle 101 of one-level main jet 1, and promptly nozzle 201 is directly to nozzle 101, and the nozzle 202 of secondary main jet 2 aligns with the nozzle 102 of one-level main jet 1; Be nozzle 202 directly to nozzle 102, above-mentioned one-level main jet 1 is swung with Button Block 3 with secondary main jet 2 synchronously.Button Block pin 4 and back Button Block pin 5 before above-mentioned Button Block 3 is provided with, preceding Button Block pin 4 is the oscillation center of Button Block 3 with the axle center at Button Block pin 5 places, back.
Above-mentioned one-level, secondary main jet can also be taked the nozzle of other equal numbers, as respectively taking a nozzle, three nozzles or four nozzles etc.
The part of not addressing in the aforesaid way can be taked or use for reference prior art and realize.
Also need to prove, any equivalent way that those skilled in the art have done under the instruction of this specification, or obviously variant all should be in protection scope of the present invention.
Claims (3)
1. an air-jet loom double pendulum moves the main jet weft insertion device; Comprise one-level main jet and secondary main jet; It is characterized in that: said one-level main jet and secondary main jet are arranged on the same Button Block and with this Button Block to be swung synchronously; One-level main jet position is preceding, secondary main jet position after, the nozzle of secondary main jet aligns with the nozzle of one-level main jet one by one.
