Composite double ingot set false twisting device of false-twist texturing machine

Abstract

The compound double spindle false twisting device for false twist texturing machine contains two spindle sets comprising one driving spindle and two driven spindles each with spindle centers constituting one equilateral triangle, one motor to drive two driving spindles in these two spindle sets, two spindle seats, one support for the spindle sets, the motor and the spindle seats to be set on, one on-line tensioner, and one motor controlling switch. One such compound double spindle false twisting device can perform S twisting and Z twisting simultaneously. The compound double spindle false twisting device has smart structure, smooth and stable false twisting and easy control.

Description

technical field [0001] The invention relates to a component of a false twist texturing machine in a textile machine, in particular to a compound double spindle group false twisting device of a false twist texturing machine. Background technique [0002] False twist texturing machine, also called elastic yarn machine or texturing machine. In the existing false twisting device, each spindle group is equipped with three spindle shafts, one driving shaft and two driven shafts. The distance between the centers of the three spindle shafts forms a triangle, and the friction discs on the three shafts are in the center of the triangle. superimposed on each other in a certain order. The synchronous toothed belt and toothed belt pulley between the driving shaft and the driven shaft make the friction discs on the three spindles rotate in the same direction, so as to perform false twisting on the silk. [0003] A group of false twist spindles can only spin one chemical fiber filament. ...

AI Technical Summary

Problems solved by technology

[0004] Due to the use of adjacent configurations to apply S twist and Z twist to the yarn, the utilization rate of the machine is reduced, and half of the winding devices for false twist deformation are in an idle state, so the energy consumption per unit of finished product increases and the cost is high

In addition, since the twisting devices are arranged adjacently, it is impossible to design the yarn lines in a very close position, which makes the trajectory of the yarn twists and turns, thus affecting the tension of the yarn and reducing the quality of the textured yarn

[0005] Furthermore, since the current manufacture of S+Z ply yarns, the rotation of the driving shaft of each spindle group is simultaneously driven by a dragon belt, and the dragon belt drives the spindle shaft of the false twisting device to rotate at high speed through friction, The spindle shaft of the false twisting device keeps in contact with the dragon belt through the pre-tightening force of the spring. In the actual process, due to the vibration of the machine, the false twisting device will resonate at a certain frequency, causing the false twisting device to vibrate, and the bearing cannot be in harmony with it. The dragon belt maintains good contact, so it directly affects the quality of the false twist textured yarn and the quality of the ply

[0006] In addition, because the transmission force of the dragon belt is too large, the wear of the dragon belt is also great. The degree of wear on the dragon belt is inconsistent, which will cause inconsistent transmission speed and the loss of twist, so it will directly affect the false twist textured yarn. quality
