In this embodiment, the silk thread can be guided into the twisted silk portion 2 by utilizing the mutual matching of the lower wire feeding assembly 31 and the upper wire feeding assembly 32, so that the technical problem that the silk thread is easy to break due to bending and tightening is solved, meanwhile, the continuous false twisting and elasticizing treatment of the silk thread is also realized, and the problem that the bending line of the bent silk thread is straightened again due to clamping force when the bent silk thread is output outwards is solved through the clamping and conveying design of the upper wire feeding assembly 32 on the silk thread.

As shown in fig. 3, the lower wire feeding assembly 31 includes a wire feeding space 311 opened at one side of the bottom of the rack 1, and a lower nip roller 312 installed in the wire feeding space 311 and arranged in a vertical direction of the yarn texturing.

In the embodiment, the lower clamping roller 312 arranged along the vertical direction of the yarn texturing is driven to rotate by the power of the preferred servo motor, so that the problem that the lower end of the yarn is separated from the lower clamping roller 312 when the yarn is pushed to one side for texturing is solved.

As shown in fig. 3, the upper nip roll 312 includes a discharge space 321 disposed on one side of the top of the frame 1, an upper nip roll 322 disposed along the yarn texturing direction, and a pinch motor 323 disposed on the frame 1 and having a power end connected to the upper nip roll 322.

In this embodiment, the pinch motor 323, preferably a servo motor, drives the upper nip roller 322 to rotate, so as to drive the wire arranged in parallel with the upper nip roller 322 in the elasticizing direction to be output outwards under the rotating power of the upper nip roller 322.

EXAMPLE III

step one, clamping the silk thread, wherein the opening and closing power part 23 drives the pushing and twisting component 21 to move towards two bent sides of the silk thread so that the silk thread is in a clamping state, and meanwhile, the pushing and twisting component 21 drives the traction processing component 22 to move the clamping terminal 22211 to two sides of the vertical direction of the silk thread bending to seal and clamp the silk thread;

feeding the silk threads, wherein the lower wire feeding assembly 31 is matched with the pushing and twisting assembly 21 and the traction processing assembly 22 to enable the silk threads to bend, and the silk threads are adaptively fed into the silk twisting part 2;

step three, adding an oiling agent, pushing the twisting power part 213 to push the twisting disks 212 towards the guide component 2223 on one side, gradually contacting the traction processing component 22 with the guide component 2223 to enable the clamping terminals 22211 to clamp the silk threads to be arranged in a bent shape, enabling the symmetrically arranged twisting disks 212 to mutually reversely drive the silk threads contacting two ends to rotate through the transmission of the transmission component 214, simultaneously controlling the leading-in component 22214 to control the oiling agent to be communicated with the conveying pipe 22213, enabling the oiling agent to enter the clamping space 22212 and coating the rotated silk threads;

step four, reversely heating and softening, namely, after the silk threads coated with the elasticizing oil return to a vertical state, continuously reversely bending under the clamping of the pushing and twisting assembly 21 and the traction processing assembly 22, controlling the leading-in assembly 22214 to guide the heating gas into the clamping space 22212 to soften the silk threads which are in rotary false twisting while the twisting disc 212 reversely drives the silk threads to rotate and false twist;

step five, cooling, namely controlling the leading-in component 22214 to control cooling air to enter the clamping space 22212 when the yarn is reversely pushed to the maximum false twisting and bending stroke by the pushing and twisting component 21 and the traction processing component 22 so as to ensure that the false twisting yarn is hardened by heat dissipation;

and sixthly, arranging wires, namely rotating the upper wire feeding assembly 32 arranged along the elasticizing width direction, so that the shaped elasticizing wires clamped by the upper wire feeding assembly 32 are output outwards along the rotating direction of the upper wire feeding assembly 32.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
