A lift-type high-speed yarn doubling machine

Abstract

The invention discloses a lifting type high-speed doubling machine. The forming part includes a stepping motor, a first fixing plate and a second fixing plate. The output end of the stepping motor is fixedly connected with a stepping motor synchronous wheel. The first guide rail and the second guide rail are fixedly connected between one side of the first fixing plate and the second fixing plate, and the stepping motor will Drive the slider to move up and down, plus the winding movement of the spindle DC motor to form a spiral winding movement of the yarn. After the stepping motor starts to run, the yarn wound in the back will have a step up and down relative to the yarn in the previous circle. amount, so that the circular operation makes the yarn spirally wind on the upper inclined surface, and do reciprocating spiral winding up and down, inside and outside, so that the unwinding tension in the back road is balanced and stable, which can greatly reduce the yarn breakage rate, twist Less unevenness and better quality; twisting speed is significantly increased.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a lifting type high-speed doubling machine. Background technique [0002] The two-for-one twister is a kind of twisting equipment, which can realize two twists in one turn, and the twisting efficiency is doubled compared with traditional twisting equipment. The package capacity is increased, 10,000 meters without joints, the twisting quality is greatly improved, and the lower layer height is especially suitable for operation. Yarn doubling machine is used to combine cotton, wool, silk, chemical fiber and other pagoda bobbins and spun bobbins into strands for twisting. Yarn doubling refers to the working steps of combining more than two yarns into one yarn Generally, there is a yarn guide part on the yarn doubling machine, and the yarn is guided by the yarn guide part to facilitate yarn doubling. [0003] The existing doubling machine yarn arrangement is unreasonable, ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a lifting type high-speed doubling machine, which solves the unreasonable arrangement of the yarns in the existing doubling machine, the unsteady tension is not stable enough, and it is easy to cause the yarn to break. Uneven twist, which leads to poor quality; small package volume leads to increased splicing and increased labor intensity
