Embodiment 1
[0028] refer to Figure 1~4 , the present embodiment provides a nozzle for an air-jet loom used in fabric production, including a nozzle assembly 100 and an adjustment assembly 200, wherein the nozzle assembly 100 is used to spray weft, and the adjustment assembly 200 is used to adjust the pressure of the air injection.
[0029] Wherein, the nozzle assembly 100 includes a nozzle 101, the nozzle 101 is provided with a lead tube 102, the weft thread passes through the lead tube 102, and the nozzle 101 is provided with an air inlet 103 along the radial direction, and the gas coming in from the air inlet 103 will discharge the gas in the lead tube 102. Weft thread ejection nozzle.
[0030] Further, the air inlet 103 is connected with an adjustment assembly 200; the adjustment assembly 200 includes an air intake pipe 201, an adjustment housing 202 located in the air intake pipe 201, the adjustment housing 202 is arranged coaxially with the air intake pipe 201 and is relatively fixe...
Embodiment 2
[0041] refer to figure 1 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, and differs from the previous embodiment in that:
[0042] Wherein, the nozzle 101 is provided with a through groove 101a, the through groove 101a includes an accommodation groove 101b, a tapered groove 101c and an outlet groove 101d, the lead pipe 102 is fixed in the through groove 101a, and the part of the lead pipe 102 located in the tapered groove 101c A tapered pipe 102a is provided, and the outline area between the tapered pipe 102a and the tapered groove 101c decreases from the direction of the accommodating groove 101b to the direction of the outlet groove 101d. The purpose of setting the tapered shape is that when the gas enters the tapered groove 101c, the pipe diameter becomes smaller and smaller, thereby forming a Venturi effect and increasing the pressure of the passing gas.
[0043] Further, the lead pipe 102 is provided with a circu...

Abstract
The invention discloses a nozzle for an air-jet loom used for cloth production, which comprises a nozzle assembly, which includes a nozzle, a lead pipe is arranged inside the nozzle, an air inlet is arranged radially in the nozzle, and the air inlet The mouth is connected with an adjustment assembly; the adjustment assembly includes an air intake pipe, an adjustment housing located in the air intake pipe, a number of fan blades are uniformly arranged between the air intake pipe and the adjustment housing, and the inner wall of the air intake pipe is evenly arranged There are a number of first mounting holes, the adjusting housing is provided with second mounting holes with the same number and coaxiality as the first mounting holes, the fan blade is provided with a rotating shaft, and one end of the rotating shaft is connected to the first mounting hole. One installation hole is connected, and the other end passes through the second installation hole; the present invention adjusts the airflow pressure according to different weft materials, so as to be suitable for weft weaving of various specifications.
Description
technical field [0001] The invention relates to the textile field, in particular to a nozzle for an air-jet loom used for cloth production. 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. Among several shuttleless looms, the air-jet loom is the one with the highest speed. Due to the reasonable weft insertion method, high weft insertion rate, easy and safe operation, wide variety adaptability, low machine material consumption and high efficiency , high speed, low noise and other advantages, it has become one of the most promising new cloth machines. The higher the clustering of the air jet, the better the weft insertion effect. The airflow ejected from the nozzle of the existing air-jet loom has a relatively large swirl, the clustering property is not high enough, and the pressure of the ejected airflow is inconvenient to adjust...
