Tensioning device for chemical fiber textured yarn

Abstract

The invention provides a tensioning device for chemical fiber draw texturing yarn, and belongs to the technical field of chemical fiber draw texturing yarn processing. The tensioning device comprises a tensioning position adjusting mechanism and a tensioning force adjusting mechanism, a tensioning supporting seat is arranged on a machine frame in a left-right sliding mode through matching of a sliding block and a sliding groove, a front gear and a front rack of the tensioning position adjusting mechanism are meshed with each other, and a rear gear and a rear rack of the tensioning position adjusting mechanism are meshed with each other. The tension adjusting mechanism comprises a front tension roller assembly, a rear tension roller assembly and a tension adjusting assembly, a tension adjusting sliding block of the tension adjusting assembly can be arranged in a tension adjusting sliding groove of a tension supporting seat in an up-down sliding mode, and a tension adjusting lead screw is connected with a tension adjusting sliding block lead screw. The tension adjusting handle is coaxially installed at the upper end of the tension adjusting lead screw, and the front tension roller assembly and the rear tension roller assembly are symmetrically arranged front and back. According to the tensioning device, the tensioning position of the chemical fiber textured yarn can be adjusted, the tensioning force is adjustable, and processing of the chemical fiber textured yarn is facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical fiber and stretched yarn processing, in particular to a tensioning device for chemical fiber and stretched yarn. Background technique [0002] Chemical fiber yarn is a fiber with textile properties that is made from natural polymer compounds or artificially synthesized polymer compounds through the processes of preparing spinning dope, spinning and post-treatment. The main varieties of chemical fiber are polyester, nylon, spandex, viscose and so on. The manufacture of chemical fiber stretched yarn is usually made of natural or synthetic polymers or inorganic substances into spinning melt or solution, and then filtered, metered, extruded from the spinneret into a liquid stream, and then solidified and formed. into fibers. The fiber at this time is called primary fiber, and its mechanical properties are very poor. It must go through a series of post-processing procedures to meet the requirements ...
