By setting the second wire drum smaller, the pulling wire is pulled downward when passing through the second wire drum, so that the pulling wire has a certain pressure;

At the same time, the warning light on the side of the corresponding third wire hole is controlled to light up, which is convenient for observing the hole where the broken wire is.

[0022] (1) This solution sets up a detection mechanism, and the second electric push rod can be used to control the movement of the mobile frame.

[0023] (2) This solution provides a support mechanism, a second spring to support the movable frame, a guide rail to limit the moving direction of the movable frame, and a support wheel to support the pull wire in the third wire hole, thereby reducing friction between the pull wire and the inner wall of the third wire hole;

[0024] (3) This solution provides a wire-breaking clamping mechanism. By providing a first electric push rod, the movement of the clamping plate can be controlled. The movement of the clamping plate can clamp the wire inside the first wire hole. By providing a first mounting pad and a second mounting pad, the wire can be better clamped and damage to the wire can be reduced.

[0025] (4) This solution can support the connecting member by setting a first spring, so that the supporting member has a moving buffer space, avoiding the supporting member from exerting a large pressure on the pulling wire during the detection process, while ensuring the detection effect.

The diameter of the second wire reel 4 is smaller than that of the third wire reel 5, and 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 wire breakage.

[0048] 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 splint 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 side of the corresponding third wire hole 52 is controlled to light up, so as to facilitate the observation of the broken hole.
