Yarn guiding mechanism on textile machines

Abstract

The present invention discloses a yarn reciprocating movement device for a spinner, particularly discloses a device used for reciprocating movement of yarn. Yarn is winded on a bobbin which is installed in the winding mechanism of an operating unit of the spinner. The device of the invention comprises a vertical reciprocating rod (2) shared by a row of operating units, the vertical reciprocating rod (2) is connected with a driving mechanism generating straight-line reverse movement and also is connected with a control system (5) which locates the die point route of the vertical reciprocating rod (2); simultaneously, the vertical reciprocating rod (2) is parallel to the winding shaft of a row of operating units. At the same time, two pairs of magnets (21,121; 22,131) are mutually arranged on the reciprocating rod (2) and the machine frame (1) at intervals, wherein each pair of magnets include a static magnet (121,131) and a moving magnet (21, 22), and the magnets are installed in such a way that magnets having the same polarity are arranged relative to each other. The static magnet is arranged on the machine frame, and the moving magnet is arranged on the reciprocating rod.

Description

technical field [0001] A device for reciprocating yarn (yarn traversing), the yarn is wound on a bobbin installed in the winding mechanism of the operating unit of the textile machine, the device includes: a longitudinal reciprocating rod shared by a row of operating units, the reciprocating The rod is coupled to a drive that produces a linear reverse motion, and to a control system that defines the course of the up and down travel of the reciprocating rod, while the longitudinal reciprocating rod is parallel to the longitudinal winding axis assigned to a row of operating units. Background technique [0002] Yarn reciprocation during bobbin winding of a textile machine such as an air spinning machine, winding machine or two-for-one twisting machine is usually performed by means of a continuous reciprocating rod advancing along one side of the machine operating unit. In the case of a large number of operating units arranged in a row, the reciprocating rods are, for example, 3...

AI Technical Summary

Problems solved by technology

These springs cause shock and vibration to this reciprocating rod and they also have a short lifespan

[0012] In addition, most of these devices cannot adjust the lifting stroke of the reciprocating rod and thereby change the width of the package on the bobbin

The reciprocating rod is often subjected to enormous pressures, requiring a corresponding increase in cross-section, which in turn leads to an increase in the weight of the distributing rod, which in turn increases the undesired inertial forces
