[0003] In the prior art, new spinning frames have begun to adopt automatic doffing technologies such as integral doffing, while most of the old spinning frames used in large quantities in my country's spinning mills still use manual doffing. Since the full yarn tube and the spindle are closely matched, a lot of force is required to pull out the full yarn tube when doffing, which makes the manual doffing work very intensive, increases labor costs, and reduces production efficiency. Therefore, it is necessary to design an intelligent doffing device for cotton yarn spinning frames. Utility Model Content
