[0002] Foreign fibers in cotton refer to non-cotton fibers and colored fibers mixed in cotton. These impurities have a serious impact on the quality of cotton and its products. Therefore, when using cotton products, it is necessary to use a foreign fiber extraction device to extract the foreign fibers in the cotton to obtain high-quality cotton.

[0003] When the cotton foreign fiber extraction device is in use, the high-definition camera inside the device captures the image of the cotton, and the foreign fibers and impurities therein are identified through image processing technology, so that the mechanical separation system separates the foreign fibers and impurities from the cotton according to the identification results. The separated foreign fibers will enter the collecting net with an opening at the bottom for collection. When using the extraction device, the bottom end of the collecting net is usually wrapped and tied, and the bottom end of the collecting net is untied when the foreign fibers inside the collecting net need to be released. However, when there are too many foreign fibers inside the collecting net, the bottom end of the collecting net may open due to poor tightening effect, causing the foreign fibers to scatter. When the tightening effect of the bottom end of the collecting net is good, it is inconvenient to open the bottom end of the collecting net to take out the foreign fibers, resulting in certain limitations when using the extraction device.
