Embodiment 1

[0035] The fineness of the spun yarn is 60, the yarn variety is pure cotton combed yarn, the twist of the yarn is S twist, the rotating speed of the spindle bar 23 of the spinning frame is set to 16000 rpm, and the steering of the drive shaft 1 is selected to be clockwise positive. Turn, the number of twists applied when the fiber strands 8 gather is set to 12, the selected inner wall included angle is the coagulation groove 10 of 80°, the plug-in 11 selects its inner diameter d=2.0, adjusts the rotating speed of the output round roller group 7, and The pull-out tension of the fiber bundle 6 is set to 1.01; after setting the above parameters, turn on the power to start spinning, and the spun yarn is tested in a standard laboratory, and compared with the results of the ring spinning test under the same conditions, it is shown that, The number of harmful hairiness values ​​is reduced by 47%, and the average breaking strength unevenness is reduced by 11.2%.

Embodiment 2

[0037]The fineness of the spun yarn is 30, the yarn variety is polyester-cotton 35 / 65 blended yarn, the twist direction of the yarn is S-twist, the rotating speed of spindle bar 23 of the spinning frame is set to 15000 rpm, and the direction of drive shaft 1 is selected to be smooth. The hour hand rotates clockwise, the number of twists applied when the fiber strands 8 are gathered is set to 15, the selected coagulation groove 10 with a smooth surface on the inner wall, the insert 11 selects its inner diameter d=3.0, adjusts the rotating speed of the output round roller group 7, and the fiber The pull-out tension of bundle 6 is set to 1.02; after setting the above parameters, turn on the power to start spinning, and the spun yarn is tested in a standard laboratory, and compared with the results of the ring spinning test under the same conditions, it is shown that its The number of harmful hairiness values ​​decreased by 39.4%, and the average breaking strength unevenness decrea...

Abstract

The invention proposes a fiber strand gathering device, which consists of: a driving shaft, a rotating cover, a fiber strand, a fiber bundle, and an output round roller group. The rotating cover is driven to rotate by the driving shaft, and the rotating cover is a structure with a small mouth and a big belly. , a condensation groove is arranged in the rotating cover, the middle part of the inner wall of the condensation groove has an angle a, and the angle a is 30°‑120°, a cover is arranged on the upper part of the condensation groove, and the cover is installed on the upper opening of the rotating cover. A socket is provided at an eccentric position on the cover, and an insert is inserted into the socket, and a yarn drawing hole is also provided in the middle of the cover, through which the fiber bundles are led out into the output round roller group. The beneficial effects are: the formed yarn has less hairiness, and the subsequent fabric has good wear resistance; the parallel straightness of the fibers is good, and the yarn strength is high; the twist of the yarn is appropriately reduced, and the yarn output speed can be increased, and the output can be increased.

Description

technical field [0001] The invention relates to the spinning field of spinning frames, in particular to a fiber whisker gathering device. Background technique [0002] There is a special problem in the normal spinning process of the ring spinning frame. The fiber strands output from the drafting area are twisted and wound by the twisting and winding mechanism through the yarn guide hook. In this process, adding The twist generated by the twisting mechanism is transmitted upward along the strands, passes through the yarn guide hook, and reaches the nip of the first round roller group, where a twisting triangle is formed. Because the twist transmission path is too long, the control of the fiber in the fiber strands in the twisting triangle area is unstable, resulting in excessive yarn hairiness, uneven yarn strength, and prone to end breakage during the production process. [0003] At present, there have been many researches on how to reduce the spinning method of the twistin...
