Abstract

Disclosed is an airflow weft catch device. The airflow weft catch device comprises a horn-shaped air suction component (300); the air suction component (300) is formed by an inner housing (120) and an outer housing (110), disposed at a weft catch end of a weaving machine and located before a weft catch device (200) of the weaving machine; a hollow channel (150) is formed between the inner housing (120) and the outer housing (110); an air hole (100) is formed at the narrow-mouthed end of the air suction component (300); an annular air outlet (130) is formed at the inner edge of the wide-mouthed end of the air suction component (300), points to the narrow-mouthed end of the air suction component (300), and is connected with the air hole (100) through the hollow channel (150); the air hole (100) is connected with a fan. In the airflow weft catch device, an airflow enters the air hole, passes through the hollow channel, arrives at the annular air outlet, and then quickly flows to the narrow-mouthed end of the air suction component; the high-speed airflow can catch a weft and then guide the weft to pass through the air suction component until the weft catch device catches the weft. Since the wide-mouthed end of the air suction component is large and the narrow-mouthed end of the air suction component is small, the weft can be caught and positioned easier; moreover, the high-speed airflow can effectively prevent the weft from coming off.
