Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] A fixed main nozzle for an air-jet loom, such as figure 1 , figure 2 As shown, it includes a cylindrical main body 1, and the main body 1 is provided with a yarn inlet hole 2 for the weft yarn to pass through, and the central axis of the yarn inlet hole 2 coincides with the central axis of the main body 1. The side wall of the main body 1 is provided with an air inlet 3 that communicates with the yarn inlet hole 2, and during the use of the fixed main nozzle, the air inlet 3 needs to communicate with the air outlet of the air compressor through the air pipe. The side of the air inlet hole 3 close to the yarn inlet hole 2 is the acceleration section 31, and the inner diameter of the acceleration section 31 gradually decreases toward the side of the yarn inlet hole 2, so that when the compressed air flows through the acceleration section 31, the flow r...

Abstract

The invention discloses a fixed main nozzle used for an air jet loom, and relates to the technical field of air jet loom assembly. Main points of the technical scheme are that the fixed main nozzle comprises a main body, the main body is provided with a yarn inlet hole for a weft yarn to pass through, and the yarn inlet hole extends along an axial direction of the main body. The side wall of the main body is provided with an air inlet hole communicated with an air inlet of an air compressor, and the air inlet is communicated with the yarn inlet hole. The internal of the air inlet is provided with an elastic filter cloth used to filter compressed air, and the elastic filter cloth is distributed along a radial direction of the air inlet. The elastic filter cloth is arranged in the air inlet,and the elastic filter cloth can filter impurities in the compressed air, so the impurities do not easily adhere on the weft yarn in the yarn inlet hole, so as to ensure a cloth woven finally is highin quality.

Description

technical field [0001] The invention relates to the technical field of air-jet loom components, in particular to a fixed main nozzle for an air-jet loom. Background technique [0002] At present, the Chinese patent with the notification number CN107675337A discloses an air-jet weft insertion mechanism capable of improving accuracy, including yarn bobbins, weft yarns, yarn guides, fixed main nozzles, swinging main nozzles, special-shaped reeds, and auxiliary nozzles. The weft yarn is exported to the fixed main nozzle through the yarn guide, and the weft yarn ejected from the fixed main nozzle is introduced into the oscillating main nozzle, and the weft yarn exported from the oscillating main nozzle passes through the reed hole of the special-shaped reed, and is connected to the shed along the reed hole of the special-shaped reed. [0003] During use, it is necessary to connect the air compressor to the inner cavity of the fixed main nozzle, and inject compressed air into the ...
