[0037] Working principle:

[0038] In actual use of the yarn guiding mechanism for a spinning frame, the operator manually moves the mounting frame 7. When the four sets of V-shaped rollers 18 are positioned above and below the yarn guide rod, the operator manually rotates the extension shaft 21, which drives the first bidirectional lead screw lever 9 and the main gear 22 to rotate. Since the first bidirectional lead screw lever 9 is threadedly engaged with the two sets of first lead screw sleeves 11, the rotating first bidirectional lead screw lever 9 can push the two sets of first lead screw sleeves 11 away from each other. The two sets of first lead screw sleeves 11, through the two sets of sleeve plates 12, cause the two sets of arc-shaped clamps 13 to move away from each other. At the same time, since the main gear 22 is meshed with the two sets of driven gears 24, the rotating main gear 22 can drive the two sets of driven gears 24 to rotate. The rotating two sets of driven gears 24 can drive the two sets of second bidirectional lead screws through the two sets of transmission shafts 23. As rod 10 rotates, the two sets of second bidirectional screw levers 10 and four sets of second screw sleeves 15 are threaded together. The rotating two sets of second bidirectional screw levers 10 can push the two sets of second screw sleeves 15 on the same side closer together. The two sets of second screw sleeves 15 on the same side, through the two sets of concave seats 16 on the same side, bring the two sets of V-shaped rollers 18 on the same side closer together. When the four sets of V-shaped rollers 18 contact the yarn guide rod, the mounting frame 7 can be moved along the yarn guide rod. When the mounting frame 7 is moved to the appropriate position, the operator can manually rotate the extension shaft 21 in the opposite direction to bring the two sets of arc-shaped clamps 13 closer together and simultaneously move the two sets of V-shaped rollers 18 on the same side away from each other. When the two sets of arc-shaped clamps 13 contact the yarn guide rod, the mounting frame 7 is stably fixed, and the two sets of first guide rods 14 can ensure the movement of the two sets of socket plates 12. Stability is ensured by the four sets of second guide rods 19, which guarantee the stability of the movement of the four sets of concave seats 16. The mounting frame 7 ensures stable installation of the mounting mechanism without affecting its movement along the yarn guide rod, thus improving the practicality of the yarn guide mechanism for the spinning machine. Furthermore, as described above, once the mounting frame 7 is securely fixed, the operator can manually move the support frame 1. When the support frame 1 is in the appropriate position, the operator can manually rotate the two sets of mounting nuts 8 clockwise and counterclockwise using the threaded engagement of the mounting screw 6 and the two sets of mounting nuts 8. When the two sets of mounting nuts 8 contact the support frame 1, the positions of the support frame 1 and the concave frame 2 are fixed. At this point, the operator can manually thread one end of the yarn through the two sets of grooved wheels 31. The yarn is then placed against the guide wheel 4 through the gap between the guide wheel and the guide wheel 4. When the yarn is taut, the moving frame plate 5 can be moved upward through the two sets of grooved wheels 31. At this time, the moving frame plate 5 can use the two sets of connecting rods 25 to make the limiting plate 26 squeeze the telescopic spring 27. When the yarn falls off the guide wheel 4, the telescopic spring 27 is subjected to its own elastic force and can push the limiting plate 26 to move the moving frame plate 5 downward. When the moving frame plate 5 presses the button switch, the buzzer alarm 29 starts to work. The operator can judge whether the yarn has fallen off the guide wheel 4 by the sound emitted by the buzzer alarm 29, so that the operator can take timely action. The moving frame plate 5 has a prompting structure, which can prompt the operator whether the yarn has fallen off the yarn guiding mechanism, thus ensuring the continuous use of the yarn guiding mechanism of the spinning machine.
