[0027] like Figure 1-3 The second embodiment shown is mainly different from the first embodiment in that:

[0028] The dust removal member 4 includes an air pump 41 fixedly connected to the right end of the upper side of the connecting seat 1, the air outlet end of the air pump 41 is fixedly connected to the filter tank 5, the air extraction side of the air pump 41 is fixedly connected to an air extraction hood 42 near the end of the stretching adjustment member 2, a recovery box 43 is placed on the lower side of the connecting seat 1 near the air extraction hood 42, a filter plate 44 is arranged on the inner side of the air extraction hood 42, a traction rod 45 fixedly connected to the connecting frame 26 is slidably connected to the upper end of the air extraction hood 42, and a cleaning brush 46 with a bristle end in contact with the filter plate 44 is arranged on the traction rod 45 near the inner side of the air extraction hood 42;

[0031] During use, the user allows the cotton yarn to be stretched to pass through the upper side of the stretching roller 21 close to the end of the movable groove. At this time, the cotton yarn is located between the two limiting rings 22 and the lower end is in contact with the stretching roller 21. Repeat the above operation to allow the remaining cotton yarn to pass through the appropriate position of the stretching roller 21, turn the hand wheel 23, and the hand wheel 23 drives the array limiting ring 22 to move through the first screw 24, so that the limiting ring 22 is in contact with both sides of the cotton yarn, and the cylinder assembly 25 moves the connecting frame 26, the second screw 27, the array pressing plate 28, and the cursor 29 downward, and wait for the bottom of the pressing plate 28 to After the cotton yarn is pressed onto the stretching roller 21, the cylinder assembly 25 is closed, and the second screw 27 is driven to rotate by the auxiliary hand wheel. The second screw 27 drives the pressure plate 28 and the cursor 29 to move toward the adjacent limiting ring 22. After the side of the pressure plate 28 is in contact with the limiting ring 22, the auxiliary hand wheel is stopped. At this time, the two groups of pressure plates 28 press the edges of the cotton yarn, and the limiting ring 22 limits the two sides of the cotton yarn. During the transmission of the cotton yarn, the stretching roller 21, the limiting ring 22, and the pressure plate 28 cooperate with each other to perform stretching and limiting anti-bias treatment on it.
