[0025] In some embodiments, see Figure 1-Figure 6The control system includes a central processor 21, a first wireless module 22, a second wireless module 23 and a third wireless module 24.

[0026] In some embodiments, see Figure 1 The second wire reel 4 is located between the first wire reel 3 and the third wire reel 5. The diameter of the second wire reel 4 is smaller than that of the third wire reel 5. The diameter of the third wire reel 5 is smaller than that of the first wire reel 3. By setting the second wire reel 4 smaller, the pull wire will be pulled downward when passing through the second wire reel 4, so that the pull wire has a certain pressure, which is more convenient for detecting the broken wire.

[0027] The working process and principle of the present invention are as follows: when in use, the pulling wire inside the frame stranding machine body 11 is passed through the first wire hole 31, the second wire hole 41 and the third wire hole 52. By setting the second wire reel 4 to be smaller, the pulling wire will be pulled downward when passing through the second wire reel 4, so that the pulling wire has a certain pressure, so that the pulling wire in the second wire hole 41 can squeeze the support member 48 to one side, so that the connecting member 47 on one side of the support member 48 can contact the pressure sensor 45, so as to detect the pressure of the pulling wire. When the pulling wire breaks, the pressure detected by the pressure sensor 45 becomes smaller, and the central processing unit 21 receives the signal, and then controls the first electric push rod 35 to extend, so that the clamp 36 clamps the pulling wire in the first wire hole 31 as much as possible to prevent the pulling wire from flying. At the same time, the warning light 51 on the corresponding side of the third wire hole 52 is controlled to light up, so as to facilitate the observation of the broken hole.
