Auxiliary nozzle air path system for bidirectional wefting insertion air jet loom

Abstract

The invention relates to an auxiliary nozzle air path system for a bidirectional wefting insertion air jet loom. The outer end of a first air inlet and the outer end of a second air inlet in a solenoid valve seat are correspondingly communicated with a first air bag air outlet and a second air bag air outlet in an air bag respectively. A first air channel and a second air channel are arranged in the solenoid valve seat and are isolated and not communicated. A first solenoid valve and a second solenoid valve are mounted at the two ends of the solenoid valve seat respectively, the inner end of the first air inlet is connected with the first air channel through the first solenoid valve, and the inner end of the second air inlet is connected with the second air channel through the second solenoid valve. First jet air outlets and second jet air outlets are formed in the solenoid valve seat, the number of the first jet air outlets and the number of the second jet air outlets are identical with the number of auxiliary nozzles, the inner ends of the first jet air outlets are communicated with the first air channel, the inner ends of the second jet air outlets are communicated with the second air channel, and the outer ends of the first jet air outlets and the outer ends of the second jet air outlets are communicated with air inlets of first jet pipes and air inlets of second jet pipes in the auxiliary nozzles respectively. The auxiliary nozzle air path system for the bidirectional wefting insertion air jet loom is compact and reasonable in structural layout, short in air supply path and capable of stabilizing high-speed air flow and improving the quality of textiles.

Description

technical field [0001] The invention relates to the improvement of the weft insertion mechanism of an air-jet loom, in particular to an air path system of an auxiliary nozzle for a two-way weft insertion air-jet loom, which belongs to the technical field of textile machinery. Background technique [0002] The air-jet loom uses the jet air as the carrier, and through the friction between the air and the yarn, the weft yarn is pulled through the shed to form a fabric. Its special weft insertion method makes it have the characteristics of high speed and high efficiency, and at the same time, it takes into account the wide variety of adaptability, which is an important direction for the development of shuttleless looms. In recent years, both foreign manufacturers and domestic loom manufacturers have invested a lot of manpower and material resources in the research and development of air-jet looms, in order to further improve the performance of air-jet looms in terms of high spee...

AI Technical Summary

Problems solved by technology

If it is simply installed on an ordinary single-side weft insertion air-jet loom, there will be problems such as too many auxiliary nozzles and a long air supply path. In this way, how to arrange and install the air of the auxiliary nozzles more reasonably in a small space The road system becomes the difficulty of the two-way weft insertion air-jet loom
