The heating pipe 2 is disposed in the housing 1, and preferably, both ends of the heating pipe 2 may be screwed into the housing 1. Specifically, as shown in fig. 4, the heating pipe 2 includes three sections, which are a first section 201, a second section 202, and a third section 203, which are connected in sequence, wherein a plurality of annular grooves 204 are formed on outer surfaces of the first section 201 and the third section 203, which are distributed along the axial direction, and an annular protrusion 205 is formed between adjacent annular grooves 204. To prevent the wire from being snapped off by the right angle of the annular protrusion 205 and the edge of the annular groove 204 during the axial movement of the wire along the first segment 201, the edges of the annular protrusion 205 and the annular groove 204 may each have a chamfer. The second section 202 is cylindrical tubular in shape. In order to prevent the temperature difference between the first section 201, the second section 202 and the third section 203 from being large, the three sections can be integrally formed. The clamping device 3 is used to apply the wire to the outer surface of the first section 201 and the third section 203 on the heating tube 2. The number of rotors is two, respectively a first rotor 4 and a second rotor 5, both of which can rotate along their own axes to increase or decrease the number of twists of the filaments, wherein the side wall of the first rotor 4 is used to form a channel with the second section 202 of the heating tube 2 through which one filament can pass. The second rotor 5 is arranged at one end of the cooling device 6 far away from the discharge port 102, and the first rotor 4 and the second rotor 5 rotate in opposite directions. The first rotor 4 is used for twisting the thread and the second rotor 5 is used for untwisting the thread. A cooling device 6 is arranged at the outlet opening 102 of the housing 1, the cooling device 6 being used for cooling the thread.

Through the arrangement, in the technical scheme, the silk threads sequentially pass through the inner walls of the annular grooves 204 when passing through the first section 201, the motion direction of the silk threads is changed in the heating process, and the stress in the silk threads is changed, so that the twist number is increased more easily.

As shown in fig. 1 and 3, a groove matched with the annular protrusion 205 is formed between adjacent protrusions 303, when the clamping block 301 moves to the clamping position shown in fig. 3 under the pushing of the cylinder 302, the clamping block 301 and the outer wall of the heating tube 2 can form a heating channel 9 for a thread to pass through, and the cross section of the heating channel 9 is wavy at two ends and rectangular in the middle. The heating passage 9 prevents the wire from being separated from the outer wall of the heating tube 2 while moving axially along the heating tube 2, resulting in non-uniform temperature of the wire. In the heating channel 9, the wire can pass through the annular grooves 204 in sequence, and the clamping blocks 301 prevent the wire from separating from the outer wall of the heating tube 2 when the wire moves along the axial direction of the heating tube 2, so that the temperature of the wire is not uniform.

Compared with air cooling, the cooling mode has better heat dissipation effect. The end of the cooling channel 6011 away from the housing 1 is connected to a second rotor 5, the second rotor 5 is the same as the first rotor 4, but the rotation direction is opposite, as shown in fig. 1, the second rotor 5 is rotatably mounted on a support 10 connected to the cooling pipe 601, an untwisting channel 11 for passing the yarn is provided between the second rotor 5 and the support 10, the yarn is untwisted when passing through the untwisting channel 11, and finally the yarn with zero total twist number but elasticity is obtained.

The implementation principle of the embodiment is as follows:

when false twisting is performed on the filament, the air cylinder 302 is adjusted to push the clamping block 301, so that the clamping block 301 moves to the first position, and a heating channel 9 is formed between the clamping block 301 and the heating pipe 2. As the filaments pass through the first section 201, the stress within the filaments changes and the filaments tend to increase in twist count. When the silk thread passes through the second section 202, the number of twists of the silk thread is increased by the rotation of the first rotor 4, then the silk thread enters the third section 203 to be heated for primary setting, the moving direction of the silk thread is continuously changed in the primary setting process, and the setting effect is better. After the preliminary shaping, the silk threads are cooled through the cooling pipe 601, then enter the untwisting channel 11 from the cooling channel 6011 of the cooling pipe 601, the number of the twist of the silk threads is reduced under the rotation of the second rotor 5, and finally the silk threads with zero total twist number and elasticity are obtained.
