Air-jet loom

Abstract

The invention discloses an air-jet loom. The air-jet loom comprises an opening mechanism, an air flow weft introducing mechanism, and a battening mechanism, and is characterized in that the air flow weft introducing mechanism comprises a main air pump, a main nozzle, a plurality of assistant air pumps, assistant nozzle sets, and air pump transmission shafts, wherein each of the air pumps is plunger type air pump; the main nozzle is connected with the main air pump; each of the assistant nozzle sets is connected to one of the assistant air pumps, respectively; the main nozzle is fixed to a weft throwing starting point; the assistant nozzle sets are sequentially fixed to the weft throwing path; a piston rod of the main air pump is connected with the air pump transmission through a transmission subassembly; the piston rods of the assistant air pumps are connected with the air pump transmission shafts through related transmission subassemblies; all the assistant air pumps are arranged in a line along the air pump transmission shafts; and the weft is thrown between one of the assistant nozzle sets at the downstream of the weft throwing path and one of the assistant nozzle sets at the adjacent upstream in a relay way through the jetting air flow. The air-jet loom is dispensed with sharing of a main pump station of the prior art; and the air-jet loom has the characteristics of low investment on equipment, compactness in structure, energy conservation performance, and consumption reducing performance, etc.

Description

technical field [0001] The present invention relates to an air jet loom. Background technique [0002] The technical structure of the air-jet loom in the prior art mainly includes parts such as shedding mechanism, air-flow weft insertion mechanism, beating-up mechanism, warp let-off mechanism, coiling mechanism and other auxiliary mechanisms. Its main working principle is roughly: the shedding mechanism drives the heald frame to move up and down, so that the warp yarns form a shed, and the airflow weft insertion mechanism brings the weft yarns into the shed through the airflow, and then the reed is driven by the beating mechanism to enter the shed. The weft yarn is driven into the fell to weave into cloth. The above-mentioned air flow weft insertion mechanism includes a main nozzle, which is fixed at the starting point of weft yarn projection through a multi-purpose seat, and the main nozzle is connected to the main pumping station in the weaving site through an air supply ...

AI Technical Summary

Problems solved by technology

In production practice, it is found that the above-mentioned beat-up angle formed by the above-mentioned beat-up foot is suitable for a narrow range of weft density in weaving fabrics, which has considerable limitations.
