[0034] Since the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5 are both ceramic materials, the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5 are not easy to wear and burr.

[0035] The front and back sides of the inner wall of the first ceramic yarn guide disc 3 and the front and back sides of the inner wall of the second ceramic yarn guide disc 5 are fixedly connected with the third vertical column 10, and the surface of the third vertical column 10 is attached to the inner wall of the strip-shaped groove 9.

[0036] It should be noted that the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5 cannot rotate on the screw rod 1 by the cooperation of the third vertical column 10 and the strip-shaped groove 9.

[0041] The working principle of the present utility model is as follows: first, the right end of the screw 1 is fixed at a specified position on the air-jet loom, and then the elastic yarn is placed between the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5. At this time, the spring 4 pushes the second ceramic yarn guide disc 5, so that the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5 apply an extrusion force to the elastic yarn. Then, the extrusion force straightens the elastic yarn when it passes between the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5. At this time, the elastic force of the elastic yarn can be weakened, and the elastic yarn can be neatly arranged on the weft feeder.

[0042] When it is necessary to adjust the extrusion force applied by the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5 to the elastic yarn, the worm 808 is first driven to rotate by the micro motor 807, and then the second nut 6 is rotated through the cooperation of the worm 808 and the worm wheel 7. At this time, the position of the second nut 6 can be changed through the cooperation of the second nut 6 and the screw 1, and the extrusion force applied by the first ceramic yarn guide disc 3 and the second ceramic yarn guide disc 5 to the elastic yarn can be changed by adjusting the position of the second nut 6.
