Problems solved by technology

In the process of trying to apply three-ply direct twisting to save energy, because the overfeeding speed of the capstan of the three-ply twisting spindle position is the same as that of the two-ply twisting spindle position, the speed is too fast and cannot be adjusted independently, and a stable small air circle cannot be obtained.
[0004] When the three-strand straight twisting machine is threaded and threaded, the large overfeed roller of the capstan must be started and stopped flexibly. The existing technology uses an electromagnetic clutch to realize the on-off of the transmission. In this device, the friction plate and the electromagnetic armature rely on spring pressure to transmit torque. Relative slippage during the process will cause the friction plate to wear and become thinner, and the gap between the electromagnet and the armature will gradually increase beyond the limit of the suction distance, which will easily cause the large overfeed roller to fail to brake

Embodiment 1

[0043] Such as figure 1 , 2 Among them, a three-strand straight twisting machine, including two-strand twisting spindle position 1 and three-strand twisting spindle position 2, two strands of raw silk are sent to two-strand twisting spindle position 1, one of which enters two-strand twisting and twisting assembly 3 and passes through high-speed The rotating two-twisting twisting assembly 3 is thrown out to form a two-twisting outer yarn balloon 4, which is twisted with one two-twisting inner yarn 5, and the two-twisting inner yarn 5 after twisting at the two-twisting spindle position 1 is After the first overfeed assembly 7 is wound n turns, it is delivered to the outer yarn long tube 10 of the three-strand twisting spindle position 2 through the wire guide device 9, and then delivered to the three-strand twisting assembly 11 to form a three-strand twist outer yarn balloon 12, which is combined with the three-strand twisting assembly 11. The twisted inner yarn 13 is twisted t...

Embodiment 2

[0060] A method for directly twisting the three-strand filaments of the above-mentioned three-strand direct twisting machine into a thread, comprising the following steps:

[0061] S1. The single-strand raw silk is fed to the two-twisting spindle position 1, and the high-speed rotating two-strand twisting assembly 3 will throw the raw silk as the outer yarn to form a two-twisted outer yarn balloon 4, and combine it with the two-twisted outer yarn Two strands of twisted inner yarn 5 of spindle position 1 are twisted to become two strands of twisted yarn 6;

[0062] S2. After the two-ply twisted yarn 6 is wound n turns on the first overfeed assembly 7, it is transported to the three-ply twisting spindle position 2 through a wire guide device 9 comprising multiple sets of guide wheels;

[0063] S3, the two-ply twisted yarn 6 is fed into the three-ply twisted twisting assembly 11 from the outer yarn long tube 10 of the three-ply twisted spindle position 2 as the outer yarn of the ...

Abstract

The invention provides a three-ply direct twisting machine and a method for directly twisting three-ply filaments into a thread, including two-ply twisting spindles and three-ply twisting spindles, and the two-ply twisted yarn twisted by the two-ply twisting spindles is fed in the first overfeed After the component is wound n times, it is transported to the long outer yarn tube of the three-ply twisting spindle through the wire guide device, and then transported to the three-ply twisting assembly to form a three-ply twist outer yarn balloon, which is twisted with the three-ply twist inner yarn to form a three-ply twist yarn , conveyed to the finished package; at the overfeed speed of the first overfeed assembly, the size of the three-ply twisted outer yarn balloon is controlled. The invention overcomes the interference of the speed of the overfeeding assembly in the prior art on the shape of the three-ply twisted outer yarn balloon, can obtain a stable energy-saving small balloon, and the speed of the twisted yarn conveyed by the first overfeeding assembly and the second overfeeding assembly It can be independently adjusted to match the winding speed of the three-ply twisted yarn to obtain the ideal package density and improve the quality of the finished package.

Description

technical field [0001] The invention relates to the field of direct twisting machines, in particular to a three-strand direct twisting machine and a method for directly twisting three strands into a thread. Background technique [0002] The three-strand straight twisting machine is mainly used in the production of tire cord, industrial filter cloth and high-quality carpet and other industries. Chinese patent document CN101429693B discloses a method for directly twisting three-ply yarns into a thread and a twisting device. Two spindles form a station to realize one-time twisting of three-ply yarns. Both spindles are provided with damping torque control storage by electromagnetic tensioners. The wrapping angle of the yarn disc ensures the stability of the balloon, and the overfeeding devices of the two spindles share the drive shaft, and the linear speed of the overfeeding and winding of the two spindles is the same. [0003] It is known from the existing energy-saving techno...
