Description

A kind of main burner for air-jet loom

Technical field

This utility model is related to a kind of main burner for air-jet loom.

Background technology

Air-jet loom is the shuttleless loom that shed open is passed through using jet-stream wind weft traction, wherein, compressed air pass through into Pore enters air inlet chamber and forms strong eddy flow, and in order to obtain good traction effect, the air pressure of compressed air is very strong, uses for a long time Easily big to the side generation of air inlet opposition impact afterwards, it has not been convenient to change.

Utility model content

For the problems referred to above, this utility model provides a kind of main burner for air-jet loom, it is to avoid compressed air is to entering The side of pore opposition produces big impact.

To realize above-mentioned technical purpose, above-mentioned technique effect is reached, this utility model is achieved through the following technical solutions：

A kind of main burner for air-jet loom, including nozzle body and nozzle fuse, the gas being arranged in nozzle body Room, rectification room, the axis direction along nozzle body is provided with guide eyelit, and the nozzle body sets in the direction of vertical guide eyelit Be equipped with the air inlet being connected with compressed air system, the air inlet is connected with air chamber, it is characterised in that the air chamber inwall with The corresponding position of air inlet is provided with buffer gear, and the rectification room communicates with rectifier tube, and compressed air passes through air chamber, rectification Room is pooled to rectifier tube and carries out rectification to weft tracting flow in rectifier tube.

It is preferred that, in a ring, the buffer gear is in arc shape to the air chamber.

It is preferred that, the buffer gear is abrasive rubber material or metal material.

The beneficial effects of the utility model are：

Compressed air enters air inlet chamber by air inlet, and its powerful air-flow forms strong eddy flow, Ran Houjing after buffer gear The rectification room crossed between nozzle body and nozzle fuse, the air-flow for making vertical weft direction of advance weakens, and the gas of direction of advance Stream is strengthened, and reaches rectification purpose, carries out further rectification to weft tracting flow in rectifier tube, it is to avoid compressed air is to air inlet pair Vertical side produces big impact.

Specific embodiment

Below in conjunction with the accompanying drawings technical solutions of the utility model are described in further detail with specific embodiment, so that Those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to this reality With new restriction.

As illustrated in fig. 1 and 2, a kind of main burner for air-jet loom, including nozzle body 1 and it is arranged on nozzle body 1 Interior nozzle fuse 6, air chamber 4, rectification room 8, along the axis direction of nozzle body 1（Horizontal direction in Fig. 1）It is provided with and leads Yarn hole 5, the nozzle body 1 is in the direction of vertical guide eyelit 5（Vertical direction in Fig. 1）It is provided with and compressed air system 3 Connected air inlet 2, the air inlet 2 is connected with air chamber 4, and the inwall of the air chamber 4 position corresponding with air inlet 2 is provided with Buffer gear 7, the rectification room 8 communicates with rectifier tube 9, compressed air by air chamber 4, rectification room 8 be pooled to rectifier tube 9 and Rectification is carried out to weft tracting flow in rectifier tube 9.

General, the air chamber 4 is in a ring, then corresponding, and the buffer gear 7 is in arc shape, and buffer gear 7 can be with It is abrasive rubber material, or metal material.

As shown in Fig. 2 the cross section of the rectification room 8 structure of grid shape gap 10 annular in shape, the cross section of rectification room 8 is from figure Left end in 1 successively decreases to right-hand member, and the shrinkage ratio in the section of rectification room 8 is according to the requirement of wefting insertion flow velocity design, annular grid shape seam Gap 10 plays a part of to cut eddy flow, and the eddy flow of large scale is resolved into into the eddy flow of multiple little yardsticks.

Compressed air enters air inlet chamber 4 by air inlet 2, and its powerful air-flow forms strong eddy flow after buffer gear 7, then Rectification room 8 between nozzle body 1 and nozzle fuse 6, the air-flow for making vertical weft direction of advance weakens, and direction of advance Air-flow strengthen, reach rectification purpose, further rectification is carried out to weft tracting flow in the smooth rectifier tube 9, it is to avoid compression is empty The side that gas opposes to air inlet produces big impact.

Preferred embodiment of the present utility model is these are only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or directly or indirectly fortune Used in other related technical fields, it is included in the same manner in scope of patent protection of the present utility model.
