Problems solved by technology
After the weft yarn passes through the center hole of the spray needle, it flies at high speed driven by the weft insertion airflow. Since the weft yarn is in a free flying state, and it has a certain twist, and the rectifying groove is straight, it is in the flying state. There is an untwisting phenomenon in the bottom, and the untwisting phenomenon becomes more serious with the lengthening of the weft insertion length; when it is serious, it will cause the fabric to have defects such as style differences and color differences in the width direction

Embodiment Construction
[0011] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0012] As shown in the figure: the spiral yarn guide includes a yarn guide formed by the integral connection of the mounting base body section 1, the rectifying section 2 and the nozzle section 3, the rectifying section 2 is set at the front end of the mounting base section 1, and the nozzle section 3 is set At the front end of the rectifying section 2, a main spray hole is opened in the axial direction of the yarn guide. The main spray hole runs through the mounting base section 1, the rectifying section 2 and the nozzle section 3. The rear section is the guide section 4a, the aperture of the guide section 4a gradually shrinks from the rear end to the front end, and a rectification groove 2a is provided on the rectification section 2, and the front end of the guide section 4b is consistent with and connected to the rear end aperture of the ejection section 4a, ...

The invention relates to textile machinery, in particular to a spiral yarn guider of a main nozzle of an air-jet loom, and is also called spiral jet needle. According to the technical scheme provided by the invention, the spiral yarn guider comprises a mounting seat body section, a rectifying section and a nozzle jet section, which are connected to be integral, the rectifying section is arranged at the front end of the mounting seat body section, the nozzle jet section is arranged at the front end of the rectifying section, a main jet hole is arranged along the axial direction of the yarn guider and penetrates through the mounting seat body section, the rectifying section and the nozzle jet section, the front part of the main jet hole is a jet part and the back part thereof is a guide part, the aperture of the guide part reduces gradually from the back end to the front end, a rectifying groove is arranged on the rectifying section, the aperture of the front end of the guide part is equivalent to that of the back end of the jet part, the guide part and the jet part are connected, and the rectifying groove is of vortex shape. When the spiral yarn guider works, compressed air is subject to rectification by the vortex-shaped rectifying groove and afterwards enters into the main jet tube to advance in a spiral way, thus inhibiting untwisting of weft yarns, and improving quality of textile.
Description
technical field [0001] The present invention relates to textile machinery, in particular to a helical yarn guide for the main nozzle of an air-jet loom, also known as a helical jet needle. Background technique [0002] The weft insertion system of the existing air-jet loom is generally composed of main nozzles, auxiliary nozzles and the like. The structure of the existing main nozzle is as follows figure 1 shown. The needle of the main nozzle is screwed into the main spray body and fixed by a cap. After the compressed air enters the air inlet of the main spray body, it is sprayed out along the main nozzle under the action of the rectification groove of the spray needle. After the weft yarn passes through the center hole of the spray needle, it flies at high speed driven by the weft insertion airflow. Since the weft yarn is in a free flying state, and it has a certain twist, and the rectifying groove is straight, it is in the flying state. There is an untwisting phenomeno...
