Description

Technical Field

[0001] This utility model relates to the field of shuttle loom technology, and in particular to a shuttle loom anti-shuttle flying device. Background Technology

[0002] A shuttle loom is a weaving machine that uses a traditional shuttle for weft insertion. Its working principle involves a shuttle feeder and shuttle drive mechanism that throws the shuttle onto a weaving frame. The shuttle then moves back and forth along a track on the frame, weaving the weft yarns and warp yarns together to form the fabric. Shuttle looms require a shuttle anti-flying device to prevent the shuttle from flying out and causing accidents, thus protecting the workers.

[0003] Chinese Patent Publication No. (CN202595413U) discloses a shuttle protection device for an automatic loom. It includes a fixing plate and a protective net. The fixing plate is located on the right side of the front crossbeam of the automatic loom, and several hooks are provided on the right side of the fixing plate, on which the protective net is hung. This protective device is fixed to the front crossbeam of the automatic loom with screws, and the entire device is located on the right side of the front crossbeam. When the automatic loom is running, if the shuttle flies out, it will hit the protective net inside the device, causing the shuttle to fall to the ground or become stuck in the net, thus preventing it from hitting the operator and ensuring personal safety. The problem to be solved is to provide a protective device that is fixed to an automatic loom and can effectively prevent injury to the operator when the shuttle flies out.

[0004] However, the above-mentioned utility model still has the following problems: The above-mentioned utility model uses a protective net to hang on the loom to prevent shuttle from flying, but the length of the protective net needs to be customized according to the loom used, which results in poor applicability and cannot be used for looms of different models and lengths. Therefore, it needs to be improved. Utility Model Content
