Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The elastic yarn conveying device is shown in figures 1 to 3 and comprises a fixed seat 1, wherein a stepping motor 2 is connected to the fixed seat 1; a large gear disc 3 is fixedly connected to the stepping motor 2, and a small gear disc 4 is arranged on one side of the large gear disc 3 in a meshed mode; a rotary disc 5 is concentrically fixed on the pinion disc 4, and the diameter of the rotary disc 5 is larger than that of the pinion disc 4; one side of the rotary table 5 is provided with a conveying disc 6 in a clinging manner, and the conveying disc 6 is rotationally connected to the fixed seat 1; and a tensioner 7 is arranged on one side of the fixed seat 1 corresponding to the conveying disc 6.
