Embodiment Construction

[0015] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0016] Such as figure 1 As shown, a nozzle of an air-jet loom produces a frictional traction force on the weft yarn through jet airflow, and brings the weft yarn through the shed to realize weft insertion. It includes a tubular nozzle body 10 and a nozzle 20 sleeved therein. An air inlet 11 communicated with the nozzle 20 is provided, and the air enters through the air inlet 11; one end of the nozzle 20 is the yarn inlet 21 of the yarn, and the other end is a spray hole 22, and the weft yarn enters through the yarn inlet 21, and in the airflow Under the action of the nozzle 22, it is ejected from the nozzle hole 22; inside the nozzle 20, ther...

Abstract

The invention relates to a nozzle of an air-jet loom. The nozzle comprises a nozzle body and a nozzle unit arranged in the nozzle body in a sleeved mode. An air inlet communicated with the nozzle unit is formed in the nozzle body. One end of the nozzle unit is a yarn inlet, and the other end of the nozzle unit is a jet hole. An air flow channel used for being communicated with the yarn inlet and the jet hole is arranged in the nozzle unit. The end, close to the yarn inlet, of the air flow channel is cylindrical, and the end, close to the jet hole, of the air flow channel is conical. The nozzle of the air-jet loom is simple and compact in structure; through the arrangement of the special-shaped air flow channel, the jet pressure is larger, air flow curl is small and strand integrity is higher, so the nozzle of the air-jet loom is economical and practical.

Description

technical field [0001] The invention relates to a device of an air-jet loom, in particular to a nozzle of an air-jet loom. Background technique [0002] The air-jet loom is a shuttleless loom that uses jet air to pull the weft yarn through the shed. The generated jet is used to achieve the purpose of weft insertion. The higher the clustering of the air jet, the better the weft insertion effect. The air flow ejected from the nozzle of the existing air-jet loom has a large swirl, and the clustering property is not high enough. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a nozzle with relatively high injection pressure, small air swirl and high concentration. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a nozzle of an air-jet loom, comprising a nozzle body and a nozzle sleeved therein, the nozzle body is provided with an air inlet communicating wi...
