Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of cotton grabbing devices, and in particular, to a cotton grabbing device for improving the toughness of cotton yarn. Background Art

[0002] The plucking device is a key piece of raw material processing equipment in the textile industry. Its primary function is to grab, loosen, and mix compacted fiber materials (such as cotton and chemical fibers), providing a uniform, loose stream for subsequent spinning. It is a crucial component of the opening and cleaning process in a spinning line and has a direct impact on yarn quality and production efficiency.

[0003] Among them, the main function of the cotton plucking machine is to grab the stacked or packaged fiber raw materials (such as cotton bales) layer by layer, break the compacted state of the raw materials, and make them initially loose. During the grabbing process, the fibers can be further loosened through mechanical action (such as beaters, blades, etc.) to reduce fiber clumping. At the same time, different raw materials can be mixed (such as different grades of cotton or cotton and chemical fiber blends) during the grabbing process to ensure uniform raw material composition.

[0004] However, cotton bales are subjected to mechanical forces (such as grabbing by beaters and tearing by rollers) during cotton grabbing and subsequent processes such as opening and combing. If the fiber toughness is insufficient, it is easy to break, resulting in frequent breakage during the spinning process and affecting production efficiency. Therefore, we proposed a cotton grabbing device to improve the toughness of cotton yarn. Summary of the Invention
