[0029] The tying machine in the application includes cutting state, rotating state and pulling forming state;
[0030] When cutting state, two hooks 9 cross each other, in the action state, clamping and rotating assembly 6 clamps the two ends of material passing through the inside of two hooks 9 that cross each other, cutting mechanism 2 is in the state of cutting off material;At this time, the next action can be done;
[0031] In the screwing state, the clamping and rotating assembly 6 drives the material to rotate 180°, and the two clamping jaws rotate from both sides, and the material is wound on the outside of the two hooks 9, so that the two hooks 9 can hook the material on both sides respectively;
[0032] In the stretching state, the two hooks 9 hook the material on both sides and retract to form a bow tie. During the stretching process, the two hooks 9 are arranged in a cross manner, and the hooks will pass through the cross during stretching, so that the bow tie can be formed. At the same time, the clamping and rotating assembly 6 loosens the material.
[0033] Therefore, the automatic mechanical structure is used to process the bow tie, so as to improve the production efficiency and solve the problem of low efficiency of the traditional manual knotting method.
[0034] In some embodiments, the drawings are combined with the Figure 2 As shown in the drawings, the first hook pulling assembly 4 and the second hook pulling assembly 5 each include a first linear driving member 7, a second linear driving member 8, a hook 9, and a limiting part 10.

The two limiting parts 10 on the first hook pulling assembly 4 and the second hook pulling assembly 5 can cross each other. The hook 9 is located in the limiting part 10 and can be partially retracted into the limiting part 10. Therefore, the material after rotation can be limited on the outside by the limiting part 10, and the retraction action of the hook 9 will not affect the material. During the stretching of the material, the two hooks 9 can pass through the inside of the material after bending, so that the bow tie can be formed.
