Embodiment Construction

[0010] Such as figure 1 As shown, a core yarn finishing twisted parallel spinning device includes a drafting device, which includes a rear roller pair 2, a middle roller pair 3 and a front roller pair 4, and an upper hollow spindle is arranged at the lower part of the drafting device 5. The top of the upper hollow spindle is open, and a yarn guide device 8 is installed inside the upper hollow spindle. The number of yarn guide devices is between 3-10. The yarn guide device includes an intermediate shaft 9, which is cylindrical. The two ends of the shaft are respectively fixed on the inner side of the upper hollow spindle, and a yarn guide wheel 10 is installed on the intermediate shaft, and the yarn guide wheel can rotate freely along the intermediate shaft, and a lower hollow spindle 6 is arranged at the bottom of the upper hollow spindle. The hollow spindle is hollow cylindrical, and the bottom end of the upper hollow spindle is interconnected with the top end of the upper ho...

Abstract

The invention provides a twisted parallel spinning device for core yarn finishing, which includes an upper hollow spindle and a lower hollow spindle. The upper and lower hollow spindles are interconnected through bearings. The hollow spindle is equipped with a yarn bobbin through a tray, and the outsourcing yarn is wound on the yarn bobbin, and the lower hollow spindle is driven by a motor through a fixedly connected belt pulley. During spinning, the staple fibers after drafting pass through the yarn guide wheels of each yarn guide device in an S-shaped route. By controlling the opening and closing of the bearings, the upper hollow spindle follows or does not rotate with the lower hollow spindle, and then Realize the finishing or twisting of staple fiber strands. The invention can realize finishing before the core yarn is wrapped by the outer covering yarn, or realize twisting of the core yarn before being wrapped by the outer covering yarn, thereby improving the yarn quality.

Description

technical field [0001] The invention relates to the new technology field of spinning, in particular to a core yarn finishing twisted parallel spinning device. Background technique [0002] Parallel spinning, also known as wrapping spinning, uses a hollow spindle for spinning, and the yarn produced by a parallel spinning machine is called parallel yarn, also known as P.L yarn. In parallel spinning, a non-twisted parallel fiber strip is used as the core yarn, and the outsourcing filament or spun staple yarn is wound on the bobbin after being wrapped into yarn. Since the fibers of the core yarn are not twisted, it is called Parallel spinning. When the yarn is stretched, the filament exerts radial pressure on the short fiber sliver, which causes friction between the short fibers and makes the parallel yarn have a certain strength. [0003] Parallel yarn can replace thread, and it is suitable for untwisted, weak twist and pile products with its unique yarn structure, giving peo...
