Automatic treatment device for warping and yarn breaking of spandex

Abstract

The invention discloses an automatic treatment device for warping and yarn breaking of spandex. The automatic treatment device comprises a closed pre-drafting device, a supporting rack, frame, a yarnfeeding assembly composed of a plurality of groups of spandex filament bobbins and a yarn guiding roller for actively feeding spandex filaments, a capacitive end breaking detector arranged at the upper end of the closed pre-drafting device and an electronic tensioner for the compensation of drafting tension of spandex, a sensor for sending end breaking signals arranged at the bottom end of the closed pre-drafting device and a brake controller responsive to the self-stop of a machine, a yarn gripper arranged at the outlet of the closed pre-drafting device, and an automatic splicer for repairing broken ends, wherein an expansion reed and a warp beam are arranged on the extension line of one side of the automatic splicer, and the distance between the capacitive end breaking detector and theclosed pre-drafting device is between 35 and 45 cm.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to an automatic processing device for spandex warping and broken yarns. Background technique [0002] Spandex is a highly elastic yarn widely used in swimwear, sportswear, underwear and other textile products. The quality of spandex warping directly affects the weaving efficiency and fabric quality, and the detection and treatment of warping broken yarn is the main factor determining its warping quality. In the past testing, there are many commonly used methods, but basically stay on the issue of whether to touch the yarn, without considering the influence of uneven tension and speed of yarn drafting. In the treatment of broken yarn after detection, in the past, it was mostly manually searched for broken yarn and then continued to start the machine after connecting it. The labor intensity was high, the work efficiency was low, and the warping quality was not high. [000...

Problems solved by technology

In the past detection, there are many commonly used methods, but basically stay on the question of whether to touch the yarn, without considering the influence of uneven tension and speed of yarn drafting

As for the broken yarn after detection, in the past, it was mostly manually searched for the broken yarn and then continued to start the machine after connecting it. The labor intensity was high, the work efficiency was low, and the warping quality was not high.

[0003] In view of this, it is necessary to provide an automatic processing device for spandex warping broken yarn with simple structure, accurate and fast response, which can not only change the inefficient and cumbersome traditional manual treatment of broken ends, realize automatic wiring processing, but also control yarn volume Winding tension, speed to reduce end breakage, and at the same time avoid yarn defects such as yarn tail loose twist caused by yarn slack and the shortcomings of being involved in the warp beam
