Abstract

The invention discloses a nozzle of an air-jet loom, which comprises a nozzle assembly, including a nozzle, a lead tube is arranged in the nozzle, an air inlet is arranged in the nozzle along a radial direction, a through groove is arranged in the nozzle, and the through groove includes a receiving groove, The tapered groove and the outlet groove, the part of the lead pipe located in the tapered groove is provided with a tapered pipe, and the contour area between the tapered pipe and the tapered groove decreases from the direction of the accommodating groove to the direction of the outlet groove; the outlet groove in the nozzle One end is connected with a cutting tube, the cutting tube is provided with a cutting hole, and the end of the cutting hole in contact with the nozzle is provided with a blade; the nozzle structure of the air-jet loom of the present invention integrates the nozzle and the blade for cutting the weft into one structure, eliminating the need for additional The cutter or scissors tangent, and simple and compact, so that the injection pressure is large, the airflow swirl is small and the clustering is high, economical and practical; at the same time, the pressure of the airflow can be adjusted according to different weft materials to apply to various specifications. weft weaving.

Description

technical field [0001] The invention relates to the field of air-jet looms, in particular to an air-jet loom nozzle. 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.
