Friction false twisting device and operation method thereof

Abstract

The invention discloses a friction false twisting device and an operation method of the device. The friction false twisting device comprises two sets of shafts which are parallel to each other and keep synchronous. Each shaft is provided with a friction disk. A friction wheel is arranged on a transmission shaft in each shaft. Nylon belts penetrate through the portion between the friction wheels to drive the two sets of shafts to rotate in the different directions. The two sets of shafts can rotate in the same direction through a synchronous mechanism. Incongruous twisting of the two sets of friction disks is achieved by means of the friction wheels and the nylon belts on the two sets of shafts, concurrent twisting is achieved through the other synchronous mechanism, setting can be carried out according to the requirement of the process, and use is flexible and convenient. When the twisting direction is changed, the nylon belts keep transmission in the same direction, the direction does not need to be changed, reverse rotating of the false twisting device is achieved through a connecting mode of the friction wheels and the shafts, and the false twisting device is suitable for producing filaments, stranded or not stranded, of yarn twisted in the same direction or yarn twisted in the different directions in the next processing procedure.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a false twist texturing machine. Background technique [0002] In the chemical fiber manufacturing process, the false twist texturing machine for false twist texturing of yarn usually has a large number of repeated spindle positions, wherein each spindle is processed by multiple processing units for at least one yarn. Each processing unit includes a raw wire frame, a hot box, a cooling plate, a friction false twist device and a winding device, which are installed on the frame to form the silk flow of each spindle, and the silk is stretched and crimped in the crimping deformation zone, and then It is wound into a silk bobbin. Any unit in the process will affect the quality of the yarn. Usually, a conventional machine of a false twist texturing machine has more than 200 spindle positions. The consistency of the yarn quality of a large number of repeated spindle positions is the ke...

AI Technical Summary

Problems solved by technology

like figure 2 As shown, the height of the machine is reduced in this way, and the cooling length 3 of the two wires at the same spindle position is basically the same. For the plying of silk, it is not allowed to produce plying yarns of the same twist and color and two monofilaments of the same quality (especially the twist)

If non-plied yarn is required in the subsequent process, when monofilament production is required, only one set of false twisting device is used for production due to the different twist directions of two sets of false twister, and half of the ingots are lost in terms of output, and the production capacity is halved.
