Nozzle mechanism of air jet loom

The utility model relates to the technical field of air jet loom components, and discloses a nozzle mechanism of an air jet loom, which comprises a nozzle mounting component and an air pressure component which is arranged outside the nozzle mounting component and is used for pressurizing and jetting air, and two groups of air guide pipes which are communicated with an air cavity in the nozzle mounting component are fixedly mounted at the front part of the nozzle mounting component. According to the utility model, when the air generated by the air pressure assembly in the mounting nozzle assembly enters the mounting nozzle assembly and is exhausted to the interior of the air guide pipe, the diameters of the plurality of groups of pressurizing guide pipe pieces are gradually reduced; at the moment, the air pressure flowing out of the air outlet end, close to the air guide pipe, of the multiple sets of pressurizing guide pipe pieces can increase the contact guide pressure on the weft yarn materials under the mat
