Intelligent spinning path detection method of chemical fiber spinning technology

Abstract

The invention discloses an intelligent spinning path detection method of the chemical fiber spinning technology. A spinning path comprises a frame and a spinning plate provided with spinning holes andarranged on the frame, and during work of the spinning plate, the spinning holes spray silk yarn units downwardly. According to the detection method, a bar-shaped laser beam irradiates the silk yarnunits, images are collected, and the number of the silk yarn units can be obtained by image identification, a worker can visually know the work condition of the spinning path via an output device instead of detection by naked eyes, the efficiency is improved more than 20 times, and abnormity of the path can be discovered promptly.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to an intelligent inspection method for a silk path in a chemical fiber spinning process. Background technique [0002] In the current chemical fiber production process, the high-pressure polyester melt is sprayed through the spinneret and cooled into fine monofilaments, and then a plurality of fine monofilaments are assembled into tows, and the tows are oiled through the nozzle to eliminate electrostatic friction and increase the hold Together, it is positioned and guided by the guide wire hook and then wound into shape. [0003] Since each spinneret has 20~576 small holes with a diameter of about 0.15mm, each tow contains 20~576 fine monofilaments, and the distance between two adjacent spinneret panels is not far (usually 10-20CM), resulting in very error-prone. For example, when the spinneret hole on the spinneret is blocked, whether all the fine monofilaments ejected from the...

Problems solved by technology

[0006] In the spinning forming process, the cost of product quality accidents is very large

If the number of monofilaments in the spinneret is incorrect, mis-segmented, floating and other monofilaments, the tow is wound into shape, and all abnormal filaments are rolled into a silk cake. At present, there is no detection method to find the problem. If it is woven into cloth, the length reaches 10,000 meters, and the economic loss caused is as high as hundreds of thousands of yuan.

When the abnormality of the Silk Road is found manually, the downstream products may have already flowed to the market, and it will take a lot of manual work to trace and settle claims, which is really laborious and costly.
