Embodiment 1
[0056] Embodiment 1 Auxiliary nozzle for air-jet loom
[0057] Such as figure 1 As shown, the present embodiment is an auxiliary nozzle for an air-jet loom, including a nozzle seat 1 and a nozzle 2 pierced and installed in the center hole of the nozzle seat 1 . The spray end of the nozzle 2 has a first spray head 3 and a second spray head 4 arranged in parallel, and each of the first spray head 3 and the second spray head 4 is provided with an air spray hole 5, and the direction of the two air spray holes 5 is consistent.
[0058] Depend on figure 2 , image 3 It can be seen that the air injection holes 5 in this embodiment are all rectangular.
[0059] Such as image 3 As shown, the nozzle 2 is provided with an airflow chamber 6, the first spray head 3 is provided with a first airflow passage 7 communicating with the airflow chamber 6, and the second sprayhead 4 is provided with a second airflow passage 7 communicating with the airflow chamber 6. The airflow channel 8,...
Embodiment 2
[0082] Embodiment 2 A kind of air-jet loom
[0083] Such as Figure 11 As shown, the present embodiment is an air-jet loom, including a profiled reed 17 provided with a weft passage 16, a main nozzle 18 facing the starting end of the weft passage 16, and auxiliary nozzles in Embodiment 1 arranged in sequence along the extending direction of the weft passage 16. nozzle.
[0084] In this embodiment, the auxiliary nozzles include a front auxiliary nozzle group 19 and a rear auxiliary nozzle 20 arranged sequentially along the extending direction of the weft passage 16, and each auxiliary nozzle is controlled by an independent solenoid valve.
[0085] Wherein, the front auxiliary nozzle group 19 includes several first auxiliary nozzles 21 , and the rear auxiliary nozzle group 20 includes four second auxiliary nozzles 22 .
[0086] Since the reasonable arrangement of the auxiliary nozzles can effectively reduce the air consumption in the profiled reed, this embodiment discusses an...

Abstract
The invention discloses an auxiliary nozzle for an air-jet loom. The auxiliary nozzle for the air-jet loom comprises a nozzle body with an air flow chamber and a sprayer which is arranged on the nozzle body, wherein the sprayer comprises a first sprayer and a second sprayer which are arranged in parallel, a first air flow channel which is communicated with the air flow chamber is arranged in the first sprayer, a second air flow channel which is communicated with the air flow chamber is arranged in the second sprayer, rectangular blowholes are arranged on the first and the second sprayers, and the directions of the blowholes which are arranged on the first and the second sprayers are consistent. The auxiliary nozzle for the air-jet loom has strong injection capacity, specific performance in that the auxiliary nozzle for the air-jet loom is excellent in air flow stability on a flow channel section which is 250mm away from the blowholes, and can achieve 32m/s maximum speed of gas flow rate. Simultaneously, the first and the second sprayers respectively spray air from the upper and the lower sides of weft yarns, and enable the two sides of the weft yarns to evenly bear force, thereby being capable of perfectly maintaining kinematic velocity of the weft yarns, reducing fluctuation of the weft yarns, and guaranteeing stability of the weft yarns.
Description
technical field [0001] The invention relates to a textile equipment, in particular to an auxiliary nozzle for an air-jet loom. Background technique [0002] Existing air-jet looms generally include a profiled reed provided with a weft passage, a main nozzle facing the start of the weft passage, and auxiliary nozzles arranged in sequence along the extending direction of the weft passage. [0003] In an air-jet loom, weft insertion is mainly achieved by an air jet injected by a main nozzle into a weft guide channel provided in a shed for warp yarns and by an air jet injected by an auxiliary nozzle to assist the weft yarn to pass through the shed. Auxiliary nozzles for air-jet textiles spray before the arrival of the weft yarns, drive the air movement in front of the weft yarns, reduce the resistance of the air to the weft yarns, make the front ends of the weft yarns generate relative negative pressure, and have an attraction effect on the weft yarns, so as to supplement the am...
