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 side, and namely 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 techniques available means solving this difficult problem adopt two-way wefting insertion.But restricting one of critical component of the two-way wefting insertion of air-jet loom is at present exactly auxiliary jet.Because existing auxiliary jet can only single way jet air-flow, namely the air-flow that sprays of auxiliary jet can only the unidirectional flight of weft traction, if when weft yarn needs oppositely to fly, 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, provide a kind of two-way wefting insertion used in jet loom auxiliary jet, its structure is simple, 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 in jet pipe installing hole respectively, left secondary jet pipe is provided with at least one left-hand venthole, and right secondary jet pipe is provided with at least one dextrad venthole.
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 described left-hand venthole and the number of dextrad venthole are 1 ~ 21.
compared with prior art, advantage is in the present invention:structure of the present invention is simple, 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.
Detailed description of the invention
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 forms primarily 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 in jet pipe installing hole respectively, left secondary jet pipe 2 is provided with a left-hand venthole 4, and right secondary jet pipe 3 is provided with a dextrad venthole 5.
As shown in Figure 1, in the present invention, should stay at regular intervals between described left secondary jet pipe 2 and right secondary jet pipe 3, preferred spacing range is 5mm ~ 30mm.In illustrated embodiment; left-hand venthole 4 on described left secondary jet pipe 2, the dextrad venthole 5 on right secondary jet pipe 3 are all only have one; but in actual applications; the number of described left-hand venthole 4 and the number of dextrad venthole 5 can be set to multiple according to Production requirement; in general be 1 ~ 21; but be how many regardless of the venthole number on secondary jet pipe, all should belong to protection scope of the present invention.
During embody rule, when weft yarn flies from left to right, the left-hand venthole 4 on left secondary jet pipe 2 is closed, and dextrad venthole 5 jet-stream wind to the right of right secondary jet pipe 3, weft traction flies from left to right.When weft yarn flies from right to left, the dextrad venthole 5 of right secondary jet pipe 3 is closed, and left-hand venthole 4 jet-stream wind left of left secondary jet pipe 2, weft traction flies from right to left.So just meet the requirement of the two-way wefting insertion of air-jet loom.
