A wire guide device 21 is fixedly mounted on the outer surface of the transmission assembly, and a roller friction winder 22 is fixedly mounted on the outer surface of the body 1.

[0027] Specifically, since a guide 20 is fixedly installed on the outer surface of the machine body 1, and the guide 20 is composed of a motor, a screw and a transmission assembly, the output end of the motor is fixedly connected to the screw, a transmission assembly is provided on the outer surface of the screw, a wire guide device 21 is fixedly installed on the outer surface of the transmission assembly, and a roller friction winder 22 is fixedly installed on the outer surface of the machine body 1, the machine body 1 connects all the devices in series, and they operate synchronously when in operation, thereby realizing the overall working process of the double twisting machine.

A No. 2 spring 18 is fixedly installed inside the movable opening 15, and a bearing 16 is fixedly installed on the output end of the No. 2 spring 18. A tension traction roller 17 is connected to the inside of the bearing 16, and an overfeed roller 19 is fixedly connected to the outer surface of the No. 3 fixed rod 23.

[0034] Specifically, a mounting frame 14 is fixedly installed on the outer surface of the No. 2 fixed rod 13, and a movable opening 15 is opened on the outer surface of the mounting frame 14, and a No. 2 spring 18 is fixedly installed inside the movable opening 15, and a bearing 16 is fixedly installed on the output end of the No. 2 spring 18, and a tension traction roller 17 is connected through the interior of the bearing 16. When the parallel line passes through the outer surface of the tension traction roller 17 for traction, the tension traction roller 17 is subjected to pressure and transmits it to the No. 2 spring 18. The No. 2 spring 18 retracts backwards when subjected to pressure, thereby reducing the traction tension of the parallel line during traction, and then the overfeed roller 19 fixedly connected to the outer surface of the No. 3 fixed rod 23 is used for subsequent guidance, thereby achieving further adjustment of the tension on the outer surface of the parallel line, and avoiding the effect of the parallel line breaking caused by the insufficient tension range of the parallel line adjusted in the front part.

[0035] In the embodiment: the movable opening 15 is arc-shaped, a servo motor is fixedly installed on the outer surface of the body 1, the output end of the servo motor is fixedly connected to the inside of the third fixed rod 23 through the inside of the body 1, and the tension traction roller 17 is arranged at the lower part of the overfeed roller 19.

Moreover, the tension traction roller 17 is arranged at the lower part of the overfeed roller 19. The humidity parallel line contacts the overfeed roller 19 under the action of the tension traction roller 17, thereby reducing the effect of excessive winding tension and breakage.

[0037] Working principle: a mounting frame 14 is fixedly installed on the outer surface of the No. 2 fixed rod 13, and a movable opening 15 is opened on the outer surface of the mounting frame 14, a No. 2 spring 18 is fixedly installed inside the movable opening 15, a bearing 16 is fixedly installed on the output end of the No. 2 spring 18, and a tension traction roller 17 is connected through the bearing 16. When the parallel line passes through the outer surface of the tension traction roller 17 for traction, the tension traction roller 17 is subjected to pressure and transmits it to the No. 2 spring 18. When the No. 2 spring 18 is subjected to pressure, it retracts backwards to reduce the traction tension of the parallel line during traction, and then the overfeed roller 19 fixedly connected to the outer surface of the No. 3 fixed rod 23 is used for subsequent guidance. Compared with the related art, the utility model provides a new anti-broken yarn doubling machine with the following beneficial effects: thereby achieving further adjustment of the tension on the outer surface of the parallel line, avoiding the effect of the parallel line breaking caused by the insufficient tension range of the parallel line adjusted in the front part.
