Description

Technical Field

[0001] The utility model relates to the technical field of air jet loom equipment, in particular to a traverse following type flying flower collecting device for an air jet loom. Background Art

[0002] During the weaving process of the air jet loom, a large amount of flying cotton and cotton drop are generated due to the friction between the warp and weft yarns caused by the raising and lowering of the heddle, the air flow weft insertion and the reed beating-up. These are not only easily woven into the fabric and affect the loom efficiency and fabric quality, but also easily dirty the workshop and affect the respiratory health of employees.

[0003] The existing air jet weaving mills install a simple flying waste collection device at the lower weft of the loom. The device is composed of a square iron frame wrapped with a cotton mesh with good adhesion. Its opening is opposite to the main nozzle. During the air jet weaving process, with the impact of the compressed airflow during weft insertion, the airflow brings the flying waste at the weft to the flying waste collection device along the path of the weft yarn. The device can effectively collect the flying waste at the lower weft in actual use, but due to the rotation of fabric products with different widths, when the width of the fabric to be woven becomes shorter, the tail end of the airflow weft insertion is at a certain distance from the flying waste collection device. At this time, the flying waste brought out from the weft by the airflow will drift into the air, and only a small part will be collected by the flying waste collection device, reducing the flying waste collection efficiency, which still affects the weaving efficiency and the environment in the workshop.
