A Vacuum Auxiliary Nozzle Mechanism for Air-jet Textile Machine

Abstract

The invention provides a vacuum auxiliary nozzle mechanism for an air-jet textile machine, which includes a lower auxiliary nozzle, an air delivery seat, a slider seat, a rotating base, a crankshaft, a driving device, an isolation mechanism, and a locking plate; The upper auxiliary nozzle is movably connected; the air delivery seat is fixedly connected under the lower auxiliary nozzle, and the air delivery seat is connected with the output end of the pneumatic control valve; the input end of the pneumatic control valve is fixedly connected with an air intake pipe; the sliding The block seat is fixedly connected to the lower end of the air delivery seat; a slider seat is slidably connected to the rotating base; the output end of the driving device is connected to the driven pulley through a belt transmission; The nozzle has added the function of adjusting the spacing to be suitable for the processing of different quality textile threads, and at the same time solved the problem of complicated operation when switching the nozzles of the existing auxiliary nozzles, and further simplified the operation mode of the air-jet loom to improve production efficiency. .

Description

technical field [0001] The invention belongs to the technical field of air-jet textile devices, and more specifically relates to a vacuum auxiliary nozzle mechanism of an air-jet textile machine. Background technique [0002] The auxiliary nozzle is a device set on the weft insertion channel of the air-jet loom to draw the weft yarn by injecting air jets. The jet spreads rapidly and the effective range is short, so the weft insertion airflow in the whole process is superimposed by the jets produced by the "main nozzle" and multiple auxiliary nozzles along the process. The number of auxiliary nozzles is related to the nominal reed width of the loom. In the initial interval of weft insertion, the control force and traction force on the yarn mainly come from the main nozzle jet, and in the subsequent weft insertion interval, the corresponding auxiliary nozzle jet acts. This weft insertion method is called relay weft insertion. Along the process, the auxiliary nozzles are orga...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a vacuum-type auxiliary nozzle mechanism for an air-jet loom to solve the problem that when using the auxiliary nozzles used in the air-jet loom in the above-mentioned patent, in order to adapt to different production types, it is necessary to prepare a variety of Auxiliary nozzles with different nozzle shapes, but due to the large number of nozzles on the air-jet loom, it is very complicated to replace the nozzles, which wastes a lot of time in actual use, and it is not convenient to fine-tune the distance between nozzles according to actual needs
