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...
