[0028] As a preferred embodiment, the vertical block 11 is bolted at the top end of the support rod 16, the support rod 16 is movably provided with a limiting rod 17 at the top end, the limiting rod 17 is fixedly connected with an arc-shaped block 18 at the bottom end, and the limiting rod 17 is sleeved with a spring 19 on the outside; further, in use, the spring 19 extrudes the arc-shaped block 18, so that the arc-shaped block 18 is movably connected above the outside of the take-up reel 15, when the take-up reel 15 is working in the process of drafting the yarn, the arc-shaped block 18 assists in pressing the yarn to a certain extent, avoiding the situation that the yarn is broken in the process of drafting, and facilitating to improve the efficiency of the yarn drafting work.

[0029] In a preferred embodiment, a support roller 20 is rotatably connected to the surface of the vertical block 11, and then a group of thread guide rollers 21 are rotatably connected at equal distances to the surface of the vertical block 11 and below the support roller 20. In use, the yarn is passed around from the outside of the lower end of the rightmost thread guide roller group 21, then from the upper end of the second thread guide roller group 21, and so on, finally coming out from the outside of the bottom end of the leftmost thread guide roller group 21 and then from the upper end of the support roller 20.

The arc block 18 provides a certain auxiliary pressing on the yarn being taken up on the take-up roll 15 to avoid the yarn from breaking during the stretching process.

[0031] When it is necessary to absorb the lint generated during the yarn stretching process, a servo motor connected to one end of the lead screw 3 drives the lead screw 3 to rotate. The rotating lead screw 3 drives the moving block 4 to reciprocate on the connecting frame 2. The reciprocating moving block 4 drives the lint removal cylinder 5 and the lint removal nozzle 6 set on the lint removal cylinder 5 to move. Then, the air pump 7, through the cooperation of the hose, the lint removal cylinder 5, and the lint removal nozzle 6, can absorb the lint generated during the yarn stretching process, thereby preventing the lint from floating in the air and affecting the health of the workers. At the same time, the lint collection net 9 can also collect the absorbed lint in a concentrated manner, reducing the workload of the workers. The above is the working principle of the drafting structure of a rotor spinning machine with precise speed control.
