Multistage synchronous yarn twisting equipment

Abstract

The invention provides multistage synchronous yarn twisting equipment, and belongs to the technical field of textile equipment. The multistage synchronous yarn twisting equipment comprises a machine base, a feeding penetrating pipe rotationally connected to the machine base and a discharging penetrating pipe rotationally connected to a machine frame; main yarn threading holes allowing main yarns to penetrate through are formed in the axis of the feeding penetrating pipe and the axis of the discharging penetrating pipe correspondingly; mounting discs are fixedly arranged on the feeding penetrating pipe and the discharging penetrating pipe correspondingly; a plurality of auxiliary yarn pay-off mechanisms are arranged between the two mounting discs; each auxiliary yarn pay-off mechanism comprises two short shafts arranged on the two mounting discs respectively; a driving gear is fixedly arranged on each short shaft; a brake disc is connected to each short shaft in a sliding mode; a wedge-shaped guide part is arranged on the inner side of each brake disc; and damping structures corresponding to the short shafts in a one-to-one mode are arranged on the two mounting discs respectively. The multistage synchronous yarn twisting equipment has the advantages of being capable of simultaneously completing multi-stage twisting and the like.

Description

technical field [0001] The invention belongs to the technical field of textile equipment and relates to a multi-stage synchronous twisting equipment. Background technique [0002] Yarns used in textiles generally need to be twisted to increase their strength, increase the wire diameter, facilitate production, and make fabrics thicker. The existing twisting equipment generally can only realize the twisting of a single yarn at one time, and the multi-stage adding Twisting often needs to be realized in multiple times. Not only is the efficiency low, but the increase in the number of times the yarn is wound will also cause a decrease in its quality. [0003] Furthermore, the existing yarn twisting equipment requires a separate tensioner. The traditional tensioner can only adjust the tension during the yarn unwinding process. However, due to the large range of tension changes in the auxiliary yarn during the twisting process, spinning The yarn speed is fast (compared to the main...

Problems solved by technology

[0002] Yarns used in textiles generally need to be twisted to increase their strength, increase the wire diameter, facilitate production, and make fabrics thicker. The existing twisting equipment generally can only realize the twisting of a single yarn at one time, and the multi-stage adding Twisting often needs to be realized in multiple times, not only the efficiency is low, but the increase in the number of times the yarn is wound will also cause a decrease in its quality

[0003] Furthermore, the existing yarn twisting equipment requires a separate tensioner. The traditional tensioner can only adjust the tension during the yarn unwinding process. However, due to the large range of tension changes in the auxiliary yarn during the twisting process, spinning The yarn speed is fast (compared to the main yarn), and the tension of the yarn cannot be effectively adjusted when the auxiliary yarn is excessively unwound and loses tension, and the machine must be stopped for adjustment

That is to say, the existing equipment for tensioning the yarn is mostly unidirectional, and the yarn cannot be wound back to the spindle, which requires extremely high running stability. The auxiliary yarn has a large tension variation range, and the traditional equipment is difficult to solve the above problems
