Embodiment Construction

[0019] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0020] Such as Figure 1-3 The auxiliary nozzle of the air-jet loom shown has a total length between 41.5-42.5 mm. The auxiliary nozzle includes a nozzle pipe 1 and a nozzle seat 2. An upper chamber 4 is provided inside the nozzle pipe 1, and an interior of the nozzle seat 2 is provided. There is a lower chamber 5, the upper end of one side of the nozzle pipe 1 has a nozzle hole 3, the lower end of the nozzle pipe 1 is inserted into the lower chamber 5 of the nozzle holder 2 from the top of the nozzle holder 2, and the bottom of the nozzle holder 2 is also provided There is an air inlet 6, the nozzle hole 3, the upper chamber 4, the lower chamber 5 and the ai...

Abstract

The invention discloses an auxiliary nozzle for an air-jet loom. The auxiliary nozzle comprises a spraying pipe and a spraying base. An upper cavity is formed inside the spraying pipe, a lower cavityis formed inside the spraying base, a spraying hole is formed in the upper end of one side of the spraying pipe, the lower end of the spraying pipe is inserted into the lower cavity of the spraying base from the top end of the spraying base, an air inlet is formed in the bottom of the spraying base, and the spraying hole, the upper cavity, the lower cavity and the air inlet are communicated. The spraying pipe comprises an upper section, a transition section and a lower section, the lower section is cylindrical, the transition section is gradually decreased from bottom to top, the cross sectionof the top of the transition section is in an oval shape, the top of the upper section is further shrunk, a slope is formed on at least one side of the top, the spraying hole is formed in the slope,and the spraying angle ranges from 7 degrees to 9 degrees. After one-time accumulation and three-time pressurization, the energy consumption of the auxiliary nozzle is smaller than that of a common air-jet loom, and the weft flight speed can be increased.

Description

technical field [0001] The invention relates to the field of air-jet looms, in particular to an auxiliary 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 through the shed. The working principle is to use the air as the weft insertion medium, and use the compressed air jet to generate friction and traction on the weft yarn to pull the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet. This weft insertion method can make the loom realize high-speed and high-yield, but because the air-jet loom adopts the air-flow weft method, the biggest disadvantage is that the energy consumption is relatively high. The air consumption of the auxiliary nozzle accounts for about 75% of the air consumption of the whole machine. Therefore, whether the speed of the air-jet loom can be further increased depends on whether the weft flying speed can be furth...
