High-speed stretch yarn machine length control system with yarn-cutting control function

Abstract

The invention discloses a high-speed stretch yarn machine length control system with a yarn-cutting control function. The system is used for the production process of chemical fiber silk in the textile industry. A spindle position state acquisition circuit is used for acquiring analog signals input by different types of yarn sensors and performing state recognition, performing analog / digital (A / D) conversion according to the analog signals input by 12 channels of spindle position yarn sensors, automatically analyzing whether spindle positions are in a yarn state or in a yarn-free state, and communicating with a human-machine interface through an RS485 communication circuit. According to the system, an arrival signal is received by a micro controller unit (MCU), and a yarn at a spindle position is forcibly cut through a yarn cutter driving circuit after yarn-cutting delay time. By the system, the misoperation caused by human factors in the production process can be greatly reduced, the labor intensity can be reduced, the production efficiency can be improved, and social resources can be well optimized and human resources of enterprises can be well saved.

Description

technical field [0001] The invention belongs to the technical field of production and processing of textile raw materials, and relates to a control system of an elastic yarn machine, in particular to a length-fixing system for belt cutting control on a high-speed elastic yarn machine. Background technique [0002] With China's further integration into the WTO and the improvement of people's living standards, the textile and chemical fiber industry is facing great opportunities, but the corresponding competition is also more intense. As the world's textile production and supply center moves eastward to Asia, domestic textile enterprises are forced to shift from labor-intensive to technology-intensive, and from manual operation to automatic control, further reducing costs, improving management levels, and increasing corporate profitability. Competitiveness. [0003] In order to adapt to the development requirements of today's era, the design of the new high-speed stretch yarn...

AI Technical Summary

Problems solved by technology

In the actual production process, several ingots of elastic yarn will be fully rolled at the same time, causing the actual fixed length value to exceed the predetermined value, resulting in waste of production materials, affecting operational efficiency, and increasing the actual production cost of the enterprise
