Description

Technical Field

[0001] The utility model relates to the technical field of textile devices, in particular to a core-spun yarn drafting and tension stabilizing device. Background Art

[0002] The core-spun yarn drafting and tension stabilizing device refers to a device that ensures that the yarn maintains stable tension and uniform draft during the drafting process, especially in the production process of the core-spun yarn. Different types of core-spun yarns require different drafts and tensions. The core-spun yarn produced under inappropriate drafts and tensions has lower quality.

[0003] A core-spun yarn drafting and tension stabilizing device is described in a patent with an existing patent announcement number of CN 211338306 U. A spring is installed at the bottom end of a limit rod. The spring pushes the limit rod to cooperate with the gear to change the rotational resistance of the winding roller and the core-spun yarn. In the process of adjusting the rotational resistance, it is difficult for the gear to rotate at a uniform speed. The greater the rotational resistance, the greater the instantaneous resistance encountered by the gear during rotation. The rotation process is not smooth and uniform, which is easy to affect the quality of the core-spun yarn.

[0004] Based on this, a core-spun yarn drafting and tension stabilizing device is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
