Yarn light tester and method

Abstract

The invention relates to the yarn light testing device and method. It aims to solve the low testing efficiency and easy error occurring issue of existing technique. It comprises the component I and component II jointed into enclosed space, with its inner wall set with purple light, yarn transportation cart inside the enclosed space, with the frame of the cart connected with yarn pole. It installsthe cylinder to be tested into the yarn pole, pushing the cart to the enclosed space, turning on the purple light with the power of 36-40w, main wave length being 365-395 nm, viewing the end of the cylinder yarn, checking out those yarns with chromatic aberration out of tolerance based on their reflective rate.

Description

A yarn light inspection device and method technical field The invention relates to a yarn inspection device and method, in particular to a yarn light inspection device and method. Background technique In order to prevent the occurrence of mixed yarn defects after gray cloth dyeing or printing, which will lead to batch reduction accidents of printed and dyed fabrics, all spinning mills must control the color difference of acrylic white gray yarn within the tolerance range. Generally, they are strictly inspected when they leave the factory. The inspection methods mainly include direct observation by the inspector with the naked eye under ordinary lighting conditions and observation in a standard light box equipped with a purple light tube. The former not only requires experienced inspectors with good eyesight, but also often makes mistakes because slight color differences are difficult to detect under sunlight or white fluorescent light; the latter is only suitable for rand...

AI Technical Summary

Problems solved by technology

The object of the present invention is to provide a yarn light inspection device and method, which mainly solves the problem that the inspector directly observes the yarn in the light box with the naked eye under ordinary lighting conditions in the prior art, and the inspection efficiency is too low, so it is only suitable for random inspection. , and the technical problem of large errors; the present invention also solves the technical problems that visual errors are prone to occur because the detection environment is not detected in a confined space, resulting in false detection, missed detection, etc.
