Technical Field
[0001] The utility model relates to the technical field of blended yarn spun yarn drafting, in particular to a blended yarn spun yarn drafting device. Background Art
[0002] Blended yarn refers to yarn spun by mixing two or more different fibers in a certain proportion, such as polyester-cotton blended yarn, polyester-viscose blended yarn, etc. In the production process of blended yarn, the yarn needs to be drafted. Drafting is the process of drawing the combed slivers to make them longer and thinner, so that the fibers in them are gradually straightened, the hooks are gradually eliminated, and the slivers gradually reach the predetermined thickness. During drafting, the fibers are gradually drawn out from the surrounding fiber group one by one. Due to mutual friction, the hooks are gradually eliminated and the curls are gradually straightened. This is achieved through fiber control and speed change. In this way, the lateral connections remaining in each fiber may be completely eliminated, creating conditions for firmly establishing a regular end-to-end connection relationship. However, generally when the spun yarn is drafted, it is necessary to manually replace the drafted spun yarn, and sometimes the machine cannot control the drafting strength well during the spun yarn drafting process, which can easily cause the yarn drafting strength to be too large, resulting in yarn breakage and the like. Therefore, a blended yarn drafting device is proposed, which can wind the blended yarn around a first drafting drum, a second drafting drum and a winding drum, and automatically replace the drafted spun yarn by driving the winding drum to rotate through the rotation of the rotating rod. At the same time, the setting of the spring column can prevent the yarn from breaking due to excessive drafting strength. Utility Model Content
