Description

Technical Field

[0001] The utility model belongs to the technical field of cotton yarn processing equipment, and particularly relates to an adjustable cotton yarn tensioning device. Background Technique

[0002] Cotton yarn is yarn processed from cotton fibers through a spinning process. After being plied, it is called cotton thread. According to different spinning processes, it can be divided into carded yarn and combed yarn. During the production process of cotton yarn, specific guiding devices, such as cotton yarn winding guiding devices, can ensure the stability and efficiency of cotton yarn during the winding process. Such devices usually include components such as a U-shaped bracket, a guiding roller, and a motor, and achieve precise guiding of cotton yarn through specific designs.

[0003] For example, Chinese Patent No. CN217867471U discloses a tensioning device for cotton yarn, including a wire guiding member. A tensioning assembly is arranged on the wire outlet side of the wire guiding member. The tensioning assembly includes a support plate. Through holes are arranged on the surface of the support plate.
