[0032] Working principle: When the machine is used, the cotton yarn is fed in from the entrance slot 7, and after the cotton yarn enters the cotton yarn entry channel 17, when the cotton yarn passes through the cotton yarn entry channel 17, the entrance limiting column 18 limits the height of the cotton yarn and then pushes the cotton yarn down. After the cotton yarn enters the cotton yarn entry channel 17, it enters the entrance conveyor belt 22, and the entrance motor 25 starts to drive the entrance gear 23 to rotate to drive the cotton yarn to be transported on the entrance conveyor belt 22. The cotton yarn is transported from the entrance conveyor belt 22 to the sorting conveyor belt 32, and the sorting motor 34 starts to drive the sorting gear 33 to rotate to transport the cotton yarn on the sorting conveyor belt 32. When the cotton yarn is transported on the sorting conveyor belt 32, the sorter motor 35 starts to drive the rotating shaft 36 to rotate, and the rotating plate 37 rotates on the sorting conveyor belt 32 to push the cotton yarn out from the sorting conveyor belt 32.

The odd-numbered drying area motor 41 and the even-numbered drying area motor 41 rotate in opposite directions after starting, thereby driving the cotton yarn to be transported on the drying conveying device in turn. The fan motor 14 starts to drive the fan 15 to rotate, and the air introduced by the left wind tunnel 9 and the right wind tunnel 8 is heated by the heating plate 13. The heated air is blown to the drying area by the fan 15 through the inner wind tunnel 20. After the drying operation is completed, the cotton yarn reaches the drying conveying device at the bottom end and is transported to the outlet conveyor belt 27 at the bottom left end of the bottom drying conveying device. The outlet transmission motor 28 starts to rotate the outlet transmission belt gear 31 to discharge the cotton yarn from the cotton yarn discharge channel 47.
