Embodiment Construction

[0013] The system is simple in structure and easy to install. It is only necessary to disconnect the feed roller and thread take-off roller of the common rotor spinning machine from the drive of the main machine, and change the feed roller and thread take-off roller to be separately driven by the servo motor. The system mainly includes three parts: pattern extraction software, programmable controller, rotational speed measurement and servo actuator. Firstly, according to the pattern extraction software, the pattern to be woven is decomposed into the weaving point, and then the programmable controller program is written according to the decomposition result, and finally the spindle speed is measured by the rotational speed measurement sensor device and fed back to the programmable controller in time to drive the machine. The servo actuator changes the speed of the feeding roller and yarn drawing roller according to the design of the yarn, so as to realize the production of slub...

Abstract

The control system of slubby yarn which can be spun on the rotor type open-end spinning machine and can be directly used for forming specific pattern on the fabric face includes three portions of pattern extraction software, programmable controller (PLC) and rotating speed measuring device and servo-actuating mechanism. Said invention also provides the application method of said control system and concrete production steps of slubby yarn.

Description

technical field [0001] The invention relates to a method for controlling slub yarn, in particular to a method for producing slub yarn by using a slub yarn control system. Background technique [0002] Rotor spinning is the fastest growing spinning method among the new spinning methods. In recent years, rotor spinning not only has greatly increased in equipment and output, but also has made great progress in terms of yarn quality, variety and range of suitable spinning raw materials, high speed, and degree of automation. It has already been used in some yarn forming fields. Instead of some ring spinning machines. On the other hand, with the continuous development of society, people have higher and higher requirements for textiles. In order to further expand the functions of rotor spinning machines and develop new varieties of rotor spinning, research on the application of rotor spinning machines to spin fancy yarns, such as slub yarns, multi-component yarns, core-spun yarns...
