Description
Technical Field
The utility model relates to an independent air supply system of air jet loom especially relates to an independent air feed of air jet loom nozzle for wefting insertion system.
Background
The existing air jet loom mainly comprises an opening mechanism, an air flow weft insertion mechanism, a beating-up mechanism, a let-off mechanism, a winding mechanism and other auxiliary mechanisms, wherein the air flow weft insertion mechanism comprises a main nozzle which is fixed at a weft yarn projection starting point through a multi-objective seat and connected to a main pump station in a weaving place through an air supply pipeline, all looms or part of the looms in the weaving place share one main pump station, and the main pump station provides high-pressure air for each loom to realize the weft insertion task of the air flow weft insertion mechanism of each loom, so that the main pump station is required to be provided with a high-power motor, and even if one part of the looms stops and one part of the looms runs, the main pump station also runs at full speed, and the air supply mode not only increases the manufacturing cost of fabrics, but also causes energy waste. In view of this, separate air supply systems for air-jet looms have appeared on the market, the air supply of which comes from a separate air pump driven by a power mechanism on the loom.
Although the air supply system has been changed, the nozzle structure applied to the air jet weft insertion mechanism still continues to use the former nozzle. Referring to figure 1 of the attached drawing part of the specification, an original nozzle mainly comprises a nozzle core A, a nozzle body B and a yarn guide tube C, an internal flow field of the nozzle comprises an air chamber 2, a weft insertion flow channel area 10, a pressure sound velocity accelerating area 4, a weft injection area 8 and a weft accelerating area 9, during weft insertion, high-pressure airflow provided by an air storage tank enters a main nozzle from an air supply airflow inlet 1, the movement direction of the airflow in the air chamber 2 is disordered and disordered, after passing through a rectifying groove 3, the airflow is changed from high-speed vortex into direct current along the axial direction, the rectified airflow enters a subsonic velocity accelerating area 4, a conical sleeve 5 is further arranged between the subsonic velocity accelerating area 4 and the nozzle body, along with the continuous reduction of the area of a throat 6, the airflow velocity at a throat outlet 7 can reach or exceed the local sound velocity to meet the requirement of weft insertion, and due to the action of the high-speed airflow, a negative pressure area can be formed at the, the existence of the negative pressure leads the external atmosphere to carry the weft yarn to enter the yarn guide tube through the weft insertion flow passage 10, the high-speed airflow and the weft yarn are fully acted in the yarn guide tube C, and the weft yarn passes through the weft yarn acceleration area 9 to reach the speed required by weft insertion. Therefore, the original nozzle is complex in structure and inconvenient to install, high-strength airflow is needed for realizing smooth weft insertion of the nozzle, the strength of the airflow provided by an onboard air pump of an independent air supply system of the existing air jet loom is far insufficient, and the problem of unsmooth weft insertion can occur if the original nozzle structure is used continuously.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.
