Description

[0002] In the production and processing flow of knitted grey fabric, winder is one of core equipment, and its core function is to re-wind the small package yarn generated in knitting process into large package bobbin, to facilitate the efficient development of subsequent dyeing, weaving and other processes.The yarn winding transmission mode of current mainstream winder mainly relies on the friction transmission between groove drum and winder, i.e., through the pressure device to make the winder tightly press on the surface of the driving rotating groove drum, the rotational power of the groove drum is transmitted to the winder by the static friction force between them, and the yarn is arranged along the winder axis by the spiral groove on the surface of the groove drum, and finally the uniform winding is completed.

[0003] However, in actual application, for the winding of knitted grey fabric yarn, as the yarn continues to wind, the diameter of the winder will gradually increase from the initial empty cylinder state to the full cylinder state.The traditional friction transmission relies on "fixed pressure" to maintain the contact between the groove drum and the winder, and when the diameter of the winder increases, the contact angle and contact pressure between the winder and the groove drum will change dynamically, and the traditional transmission structure cannot adaptively adjust the distance and pressure between them, resulting in a gradual decrease in the static friction force between the groove drum and the winder, and even the groove drum idling, the winder speed drops or stalls, and further causes the yarn to "slide" on the surface of the winder, which cannot be tightly wound.
