Abstract
The invention relates to an auxiliary jet used for a two-way weft insertion air jet loom. The auxiliary jet used for the two-way weft insertion air jet loom comprises an auxiliary jet pipe base and is characterized in that two jet pipe mounting holes formed in parallel are formed in the auxiliary jet pipe base, a left auxiliary jet pipe and a right auxiliary jet pipe are installed in the jet pipe mounting holes respectively, at least one left air outlet is formed in the left auxiliary jet pipe, and at least one right air outlet is formed in the right auxiliary jet pipe. The auxiliary jet used for the two-way weft insertion air jet loom is simple in structure, reasonable in design and capable of achieving two-way weft insertion of the air jet loom and improving the quality of fabric.
Description
Technical field
The present invention relates to the appurtenances on a kind of air-jet loom, specifically two-way wefting insertion used in jet loom auxiliary jet, belongs to textile machine equipment technical field.
Background technology
The wefting insertion action of current air-jet loom is all, by air-flow, weft yarn is taken to opposite side from loom one side, and weft yarn is one-way movement.Because jet loom for drawing weft yarn belongs to free end wefting insertion, weft yarn is in the process of flight, and tension force, the twist can weaken gradually, cause fabric irregular at fabric width direction tension force, and after dyeing, aberration appears in the right and left.This is the global problem of restriction air-jet loom development, and one of available techniques means that solve this difficult problem are to adopt two-way wefting insertion.But one of critical component that restricts at present the two-way wefting insertion of air-jet loom is exactly auxiliary jet.Because existing auxiliary jet can only single way jet air-flow, the air-flow that auxiliary jet sprays can only the unidirectional flight of weft traction, if weft yarn is while needing oppositely flight, the structure of existing auxiliary jet is helpless.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of two-way wefting insertion used in jet loom auxiliary jet is provided, it is simple in structure, reasonable in design, can realize the two-way wefting insertion of air-jet loom, improves fabric quality.
According to technical scheme provided by the invention: two-way wefting insertion used in jet loom auxiliary jet, comprise secondary nozzle block, it is characterized in that: described secondary nozzle block is provided with two parallel jet pipe installing holes side by side, left secondary jet pipe and right secondary jet pipe are arranged on respectively in jet pipe installing hole, left secondary jet pipe is provided with at least one left-hand air outlet, and right secondary jet pipe is provided with at least one dextrad air outlet.
As a further improvement on the present invention, the spacing between described left secondary jet pipe and right secondary jet pipe is 5mm ~ 30mm.
As a further improvement on the present invention, the number of the number of described left-hand air outlet and dextrad air outlet is 1 ~ 21.
compared with prior art, advantage is in the present invention:the present invention is simple in structure, reasonable in design, can realize the two-way wefting insertion of air-jet loom, improves fabric quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the two-way wefting insertion used in jet loom auxiliary jet in embodiment is mainly comprised of secondary nozzle block 1, left secondary jet pipe 2 and right secondary jet pipe 3, described secondary nozzle block 1 is provided with two parallel jet pipe installing holes side by side, left secondary jet pipe 2 and right secondary jet pipe 3 are arranged on respectively in jet pipe installing hole, left secondary jet pipe 2 is provided with a left-hand air outlet 4, and right secondary jet pipe 3 is provided with a dextrad air outlet 5.
As shown in Figure 1, in the present invention, should stay at regular intervalsly between described left secondary jet pipe 2 and right secondary jet pipe 3, preferred spacing range is 5mm ~ 30mm.In illustrated embodiment; dextrad air outlet 5 on left-hand air outlet 4, right secondary jet pipe 3 on described left secondary jet pipe 2 is all to only have one; but in actual applications; the number of the number of described left-hand air outlet 4 and dextrad air outlet 5 can be set to according to Production requirement multiple; in general be 1 ~ 21; but no matter the air outlet number on secondary jet pipe is how many, all should belong to protection scope of the present invention.
During concrete application, when weft yarn flies from left to right, the left-hand air outlet 4 on left secondary jet pipe 2 is closed, dextrad air outlet 5 jet-stream wind to the right of right secondary jet pipe 3, and weft traction flies from left to right.When weft yarn flies from right to left, the dextrad air outlet 5 of right secondary jet pipe 3 is closed, left-hand air outlet 4 jet-stream wind left of left secondary jet pipe 2, and weft traction flies from right to left.So just met the requirement of the two-way wefting insertion of air-jet loom.
