[0023] An electric telescopic rod 8 is fixedly installed on the top of the guide platform 4. The telescopic end of the electric telescopic rod 8 passes through the rear side wall of the two-for-one twister body 1 and extends into the interior thereof. A threading tube 17 is fixedly installed at the end of the telescopic rod of the electric telescopic rod 8, which is relatively perpendicular to the telescopic direction of the electric telescopic rod 8. The upper and lower edges of the threading tube 17 are rounded to prevent wear on the yarn. Correspondingly, a machine door 6 is hingedly installed on the front of the two-for-one twister body 1. A threading hole 18 is opened on one side of the bottom of the machine door 6. The opening height of the threading hole 18 is lower than the lower end height of the threading tube 17. The yarn to be processed enters from the threading hole 18, through the lower end of the threading tube 17, and passes out from the upper end of the threading tube 17 and is connected to the twisting roller 14.

[0024] The top of the two-for-one twister body 1 is fixed with mutually connected ventilation chambers 5, and a partition 51 is transversely fixed in the center of the ventilation chamber 5. The top of the partition 51 is a drying chamber 52, and the bottom of the partition 51 is a cleaning chamber 53; the partition 51 is also provided with a plurality of ventilation holes 57. The top of the drying chamber 52 is connected with an air inlet pipe 56, and the inside of the drying chamber 52 is filled with activated carbon adsorption cotton 54, and the diameter of the activated carbon adsorption cotton 54 is larger than the inner diameter of the ventilation hole 57 on the partition 51; the cleaning chamber 53 is installed with a fan 55, which is fixed at the bottom of the partition 51 and acts to discharge air downward.

[0025] A purification box 10 and an extraction pump 9 are fixedly installed on the top of the purification table 2. The air inlet of the extraction pump 9 is fixedly connected to an extraction pipe 11 extending to the inside of the two-for-one twister body 1.

[0028] The specific application principle is as follows: first, the staff opens the machine door 6, passes the core-spun yarn to be processed through the threading hole 18 and the threading tube 17 in sequence to connect to the twisting roller 14, and then closes the machine door 6. The staff first turns on the guide switch 20, and the electric telescopic rod 8 starts, driving the threading tube 17 to move left and right to adjust the twisting position of the core-spun yarn to avoid the core-spun yarn from getting stuck on the twisting roller 14; then the staff turns on the cleaning switch 22, and the fan 55 starts to blow the clean and pure gas sucked in from the air inlet pipe 56 and then filtered by the activated carbon adsorption cotton 54 in the drying chamber 52 to the inside of the two-for-one twister body 1, so as to remove the impurities adhering to the surface of the core-spun yarn; since the fan 55 removes dust from the core-spun yarn, the gas inside the two-for-one twister body 1 contains impurities, and then the staff presses the exhaust switch 23, and the extraction pump 9 starts to run, and the floating dust gas inside the two-for-one twister body 1 is extracted through the extraction pipe 11, and enters the subsequent connected purification box 10 through the extraction pump 9 and the conveying pipe 12, and the interception mechanism inside the purification box 10 intercepts and purifies the impurities in the exhaust gas, and the purified gas is discharged through the exhaust pipe 19. After removing impurities, the staff turns on the twisting switch 21, the drive motor 7 starts running, drives the driving gear 15 to rotate, and drives the mounting shaft 13 to rotate through meshing with the driven gear 16, and then drives the twisting roller 14 to twist and wind the core-spun yarn.
