The working principle of the invention is as follows: when the device is used, firstly, chemical fiber silk threads needing to be guided and sent are arranged in the wire grooves 1011 on the wheel body 101, the chemical fiber silk threads are stably limited in the wire grooves 1011 by the limiting device 103, when the chemical fiber silk threads are guided and sent, the stress which acts on the guide wheel assembly 1 instantly drives the wheel body 101 to rotate, when the wheel body 101 rotates instantly, the buffering device 104 generates deformation to buffer the stress which acts instantly, then the whole guide wheel assembly 1 rotates and guides the chemical fiber silk threads on the arranging rod 201, when the arranging rod 201 receives the stress from the guide wheel assembly 1 in the process that the guide wheel assembly 1 stably rotates and guides the chemical fiber silk threads, the arranging rod 201 compresses the third spring 206 on the sleeve 202, the stress on the arranging rod 201 is buffered through the deformation of the third spring 206, the arranging rod 201 moves in the sleeve 202 to buffer the stress acting on the arranging rod 201, and the buffering rod 2 is ensured to stably guide the chemical fiber silk threads, the chemical fiber silk thread is guided and fed to provide stable tension, and when the tension changes, the buffer rod piece 2 is used for buffering the stress generated by the tension change, so that the influence on the chemical fiber silk thread is reduced;

when the chemical fiber yarn guiding tension needs to be adjusted in the using process, the adjusting rod 205 on the sleeve 202 is rotated according to actual use requirements, the lower end of the adjusting rod 205 rotates in the threaded hole 2012 at the upper end of the mounting rod 201, the mounting rod 201 is further driven to move in the sleeve 202, and the deformation amount of the mounting rod 201 and the sleeve 202 for compressing the third spring 206 is adjusted, so that the sensitivity of deformation generated in the buffering process of the buffering rod piece 2 is adjusted, and further the chemical fiber yarn supporting tension is adjusted;

when the position of the guide wheel assembly 1 needs to be adjusted in the use process, the first limiting bolt 3014 is loosened, the buffer rod member 2 is rotated on the first adjusting plate 301, the buffer rod member 2 is rotated to the position designated on the first adjusting plate 301, the first limiting bolt 3014 is tightened to fix the buffer rod member 2 at the position, then the second limiting bolt 3024 is loosened, the first adjusting plate 301 is rotated on the second adjusting plate 302, the first adjusting plate 301 is rotated to the position designated on the second adjusting plate 302, and the second limiting bolt 3024 is tightened to fix the first adjusting plate 301 at the position.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
