Abstract
The invention discloses a main nozzle for an air-jet loom. The main nozzle comprises a nozzle shell and a nozzle core, an air chamber and a rectification chamber which are arranged inside the nozzle shell. A yarn guide eyelet is arranged in the axis direction of the nozzle shell. The nozzle shell is provided with an air inlet hole in the direction perpendicular to the yarn guide eyelet, wherein the air inlet hole is connected with a compression air system. The air inlet hole is connected with the air chamber. The main nozzle is characterized in that a buffer mechanism is arranged at the position, corresponding to the air inlet hole, of the inner wall of the air chamber, the rectification chamber is communicated with a rectification pipe, compression air is collected to the rectification pipe through the air chamber and the rectification chamber and rectifies wefting airflow inside the rectification pipe, and large impact generated by the compression air on the side face opposite to the air inlet hole is avoided.
Description
Technical field
The present invention relates to a kind of main burner for 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, in order to obtain good traction effect, compressed-air actuated air pressure is the strongest, easily the side of air inlet opposition is produced big impact after long-time use, it has not been convenient to change.
Summary of the invention
For the problems referred to above, the present invention provides a kind of main burner for air-jet loom, it is to avoid the side that air inlet is opposed by compressed air produces big impact.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of main burner for air-jet loom, including nozzle body and the nozzle fuse being arranged in nozzle body, air chamber, rectification room, axis direction along nozzle body is provided with guide eyelit, described nozzle body is provided with the air inlet being connected with compressed air system in the direction of vertical guide eyelit, described air inlet is connected with air chamber, it is characterized in that, the described air chamber inwall position corresponding with air inlet is provided with buffer gear, described rectification room communicates with rectifier tube, compressed air passes through air chamber, rectification room is pooled to rectifier tube and in rectifier tube, weft tracting flow is carried out rectification.
Preferably, ringwise, described buffer gear is arc shape to described air chamber.
Preferably, described buffer gear is abrasive rubber material or metal material.
The invention has the beneficial effects as follows:
Compressed air is entered air chamber by air inlet, its powerful air-flow forms strong eddy flow after buffer gear, 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, reach rectification purpose, in rectifier tube, weft tracting flow is carried out further rectification, it is to avoid the side that air inlet is opposed by compressed air produces big impact.
Accompanying drawing explanation

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, a kind of main burner for air-jet loom, including nozzle body 1 and the nozzle fuse 6 being arranged in nozzle body 1, air chamber 4, rectification room 8, axis direction (horizontal direction in Fig. 1) along nozzle body 1 is provided with guide eyelit 5, described nozzle body 1 is provided with, in the direction (vertical direction in Fig. 1) of vertical guide eyelit 5, the air inlet 2 being connected with compressed air system 3, described air inlet 2 is connected with air chamber 4, the described air chamber 4 inwall position corresponding with air inlet 2 is provided with buffer gear 7, described rectification room 8 communicates with rectifier tube 9, compressed air passes through air chamber 4, rectification room 8 is pooled to rectifier tube 9 and in rectifier tube 9, weft tracting flow is carried out rectification.
General, ringwise, then corresponding, described buffer gear 7 is in arc shape, and buffer gear 7 can be abrasive rubber material, it is also possible to be metal material for described air chamber 4.
As shown in Figure 2, the cross section of described rectification room 8 grid shape gap 10 structure in the form of a ring, the cross section of rectification room 8 left end in Fig. 1 successively decreases to right-hand member, the shrinkage ratio in cross section, rectification room 8 is the requirement design according to wefting insertion flow velocity, the effect of cutting eddy flow is played in annular grid shape gap 10, and the eddy flow of large scale resolves into the eddy flow of multiple little yardstick.
Compressed air is entered air chamber 4 by air inlet 2, its powerful air-flow forms strong eddy flow after buffer gear 7, the rectification room 8 being then passed through between nozzle body 1 and nozzle fuse 6, the air-flow making vertical weft direction of advance weakens, and the air-flow of direction of advance is strengthened, reach rectification purpose, in smooth rectifier tube 9, weft tracting flow is carried out further rectification, it is to avoid the side that air inlet is opposed by compressed air produces big impact.
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.
