Automatic yarn separating device for spandex filaments

Abstract

The invention discloses an automatic yarn separating device for spandex filaments, and belongs to the technical field of spandex spinning. The automatic yarn dividing device includes a driving wheel,a driven wheel and a yarn separating roll, a rotating shaft of the driving wheel is fixed on a driving roller of yarns, the driving wheel is connected with the driven wheel by a transmission belt, andthe driven wheel is connected to the driving wheel through the transmission belt in a driving mode; and the yarn separating includes a rotating shaft and a yarn separating frame, and the yarn separating frame is of a regular polygonal tubular frame, the spouted filaments are wound on the separator roll, and the yarns are automatically dispersed under the action of the pulling force and elastic force and are separated according to the pulling order of spinneret orifices, so that the purpose of automatic yarn separating is achieved; and the yarns are no longer to be separated manually, the yarnseparation speed is faster, the efficiency is high, the personnel operation is less, the technical ability requirement on the separation personnel is lower, and more people can complete the operation.

Description

technical field [0001] The invention relates to the technical field of spandex spinning, in particular to an automatic spinning device for spandex filaments. Background technique [0002] Spandex is the abbreviation of polyurethane fiber, which is a kind of elastic fiber. Spandex is generally composed of multiple filaments, usually 10D / filament, and now there are 15D / thread, or even 20D / thread. The production solution of spinning method DMAC is harmful to the liver of the human body. Generally, 10D / root contains 0.5mg / kg, and if 15D / root contains 0.7mg / kg, it exceeds the standard. There are many production methods, currently there are dry spinning, melt spinning, wet spinning and chemical reaction methods. [0003] Among them, melt spinning is a method of heating a polymer above its melting point to become a melt and form a filament. [0004] Production process: high polymer is polymerized without solvent, granulated, sliced ​​at a constant temperature, cleaned and remove...

Problems solved by technology

[0006] However, during the spinning process, the filaments just sprayed out of the spinneret are interlaced, easy to knot and uneven, and the spinneret holes are evenly arranged on the spinneret, so the sprayed spandex needs to be The filaments are elongated and stretched to the following winding machine, and the filaments are also arranged and separated on the winding machine according to the arrangement of the spinneret holes, and each filament will be wound into different coils. If these filaments If they are staggered together, there is no way to continue winding, and when spinning, many spinnerets are combined into one group, and the spinning is carried out at the same time to improve the efficiency and utilization of the winding machine. Generally, a group of spinnerets are sprayed at the same time. The minimum number of filaments is 24, and the most can reach 128. So many filaments need to be interlaced into coils on the same winding machine, and the interlacing means that each filament must be separated and not interlaced with each other.

[0007] Therefore, it is necessary to separate the thread ends that have just started to be staggered together, and then arrange them on the winding machine to be wound into a coil. At present, there is no good way to straighten the thread by manually holding the silk aspirator, and then pick it up one by one. Pull the rods apart one by one
