a third main shaft of the drafting motor is connected with a second drafting bevel gear 5 in a key way to enable the second drafting bevel gear 5 to rotate, the second drafting bevel gear 5 is meshed with the first drafting bevel gear 4 to drive the first drafting bevel gear 4 to rotate, the first drafting bevel gear 4 is fixedly connected with a drafting lead screw 19-24 to enable the drafting lead screw 19-24 to rotate along with the first drafting bevel gear, the drafting lead screw 19-24 is in threaded connection with a drafting lead screw nut 19-23 to enable the drafting lead screw nut 19-23 to move up and down on the drafting lead screw 19-24 to drive a drafting limit frame 19-22 to move up and down, the drafting limit frame 19-22 is connected with a group of fifth drafting shafts 19-20, the fifth drafting shafts 19-20 can move down under the connection of a second universal joint, when the second universal joint reaches the maximum value of downward movement, the first universal joint is driven to continue to move down through the drafting shafts 19-19, the distance between the two groups of fifth stretching shafts is changed, the two groups of fifth stretching shafts are provided with the stretching rollers 19-21 respectively, the distance between the two groups of stretching rollers 19-21 is changed, the textile thread is adjusted to be the required diameter, the main shaft of the stretching motor II 19-14 is connected with the first 19-15 key of the stretching gear I19 to 15 to drive the first 19-15 of the stretching gear I to rotate, the first 19-15 of the stretching gear I is meshed with the second 19-16 of the stretching gear II to drive the second 19-16 of the stretching gear II to rotate along with the first 19-16 of the stretching gear II, the third 19-17 of the stretching gear III rotates along with the second 19-16 of the stretching gear II when meshed with the third 19-17 of the stretching gear III, the rotating directions of the second 19-16 of the stretching gear III 19-17 are opposite, the fourth 19-18 connected with the fourth 19, ensuring the uniform drafting of the textile threads.

The control mode of the invention is automatically controlled by the controller, the control circuit of the controller can be realized by simple programming of a person skilled in the art, the invention belongs to the common knowledge in the field, and the invention is mainly used for protecting mechanical devices, so the control mode and the circuit connection are not explained in detail in the invention.

It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and that various changes, modifications, additions and substitutions which are within the spirit and scope of the present invention and which may be made by those skilled in the art are also within the scope of the present invention.
