Abstract

Winding movement of twisting machine is closely related to the package build, package density and yarn quality. The requirements are that the package build is good shaped and the winding tension is proper technically. Namely the angle of winding is fine and there is no overlapping and convex, hard edge on the package. The winding density is same and reasonable on the whole package build. And the fluctuation of winding tension is small. It is becoming development trend that driving of multiple-motors is used on twisting machine. There are many parameters to be controlled such as degree of twist, direction of twist, winding angle and spindle speed and so on. Therefore it is essential to set up reasonable mathematical model of yarn for winding movement.

Highlights

  • Twisting machine mostly adopted the single motor driving system home and abroad during the past years[1]

  • The winding movement and the reciprocating yarn guiding movement are realized by the gear wheel and the stepped cam transmission

  • In this way, twisting movement of the spindle, winding movement of rolls and reciprocating yarn guiding movement are realized on twisting machine[3]

Summary

Introduction

Twisting machine mostly adopted the single motor driving system home and abroad during the past years[1]. Direction of twist is changed by the rotation direction of the main motor. This can gain the S twist and Z twist. The winding movement and the reciprocating yarn guiding movement are realized by the gear wheel and the stepped cam transmission. In this way, twisting movement of the spindle, winding movement of rolls and reciprocating yarn guiding movement are realized on twisting machine[3]. This transmitting is long and the structure is complex. According to the characteristics of traditional twisting machine driving system, this paper puts forward a new twisting machine winding based on multi-parameter controlling system, which can satisfy the whole technological requirements of twisting machine
