The invention discloses a double-air-inlet main nozzle based on an air-jet loom. The double-air-inlet main nozzle comprises a nozzle shell and a nozzle core arranged in the nozzle shell. A yarn guide hole is formed in the axis direction of the nozzle shell. The double-air-inlet main nozzle is characterized in that an air chamber and a rectification chamber which are communicated are arranged in the nozzle shell, the air chamber is divided into an upper half portion and a lower half portion which are not communicated, the upper half portion is provided with a first air inlet connected with a compressed air system, the lower half portion is provided with a second air inlet connected with the compressed air system, and the rectification chamber is communicated with a rectification pipe. Preferably, the air chamber is annular and is evenly divided into the upper half portion and the lower half portion. Airflow distribution is more uniform, and the rectification effect on weft insertion airflow is improved.
Description
Technical field
The present invention relates to double air inlet main burner based on air-jet loom.
Background technology
Air-jet loom is the shuttleless loom using jet-stream wind weft traction to pass through shed open, wherein, compressed air enters air chamber by air inlet and forms strong eddy flow, being rectified room is divided into little air-flow to draw weft yarn, traditional main nozzle structure, only arranging an air inlet, its air flow method is uneven, and the rectification effect of weft tracting flow is not reached optimum efficiency.
Summary of the invention
For the problems referred to above, the present invention provides double air inlet main burners based on air-jet loom, and air flow method evenly, improves the rectification effect to weft tracting flow.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Double air inlet main burner based on air-jet loom, including nozzle body and the nozzle fuse being arranged in nozzle body, axis direction along nozzle body is provided with guide eyelit, it is characterized in that, the air chamber communicated and rectification room it is provided with in described nozzle body, described air chamber is divided into the first half and lower half being not communicated with, the described first half is provided with the first air inlet being connected with compressed air system and lower half is provided with the second air inlet being connected with compressed air system, and described rectification room communicates with rectifier tube.
Preferably, described air chamber ringwise and is evenly divided into the first half and lower half.
Preferably, the cross section of described rectification room grid shape gap structure in the form of a ring.
Preferably, described rectifier tube is smooth pipe.
The invention has the beneficial effects as follows:
Compressed air is entered the first half of air chamber by the first air inlet, is entered the lower half of air chamber by the second air inlet, the while that current rate improving two times, air-flow is evenly, its powerful air-flow forms strong eddy flow, the rectification room being then passed through between nozzle body and nozzle fuse, the air-flow making vertical weft direction of advance weakens, and the air-flow of direction of advance is strengthened, and reaches rectification purpose, in rectifier tube, weft tracting flow is carried out further rectification, improves the rectification effect to weft tracting flow.

Detailed description of the invention
Being described in further detail technical solution of the present invention with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As illustrated in fig. 1 and 2, double air inlet main burner based on air-jet loom, including nozzle body 1 and the nozzle fuse 4 being arranged in nozzle body 1, axis direction (horizontal direction in Fig. 1) along nozzle body 1 is provided with guide eyelit 3, the air chamber 7 communicated and rectification room 2 it is provided with in described nozzle body 1, described air chamber 7 is divided into the first half 8 and lower half 9 being not communicated with, the described first half 8 is provided with the first air inlet 5 being connected with compressed air system and lower half 9 is provided with the second air inlet 6 being connected with compressed air system, described rectification room 2 communicates with rectifier tube 10.
The most described air chamber 7 ringwise and is evenly divided into the first half 8 and lower half 9, and described rectifier tube 10 is smooth pipe.In order to improve the uniformity of air-flow, best first air inlet 5 is connected with same compressed air system with the second air inlet 6.
As shown in Figure 2, the cross section of described rectification room 2 grid shape gap 11 structure in the form of a ring, the cross section of rectification room 2 left end in Fig. 1 successively decreases to right-hand member, the shrinkage ratio in cross section, rectification room 2 is the requirement design according to wefting insertion flow velocity, the effect of cutting eddy flow is played in annular grid shape gap 11, and the eddy flow of large scale resolves into the eddy flow of multiple little yardstick.Preferably, described rectification room 2 is divided into the upper and lower part corresponding with air chamber 7, and top, rectification room 2 communicates with the first half 8, and bottom, rectification room 2 communicates with lower half 9.
Compressed air is entered the first half 8 of air chamber by the first air inlet 5, is entered the lower half 9 of air chamber by the second air inlet 6, the while that current rate improving two times, air-flow is evenly, its powerful air-flow forms strong eddy flow, the rectification room 2 being then passed through between nozzle body and nozzle fuse, the air-flow making vertical weft direction of advance weakens, and the air-flow of direction of advance is strengthened, and reaches rectification purpose, in rectifier tube, weft tracting flow is carried out further rectification, improves the rectification effect to weft tracting flow.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, is the most in like manner included in the scope of patent protection of the present invention.
