[0065] In actual use, when the first sleeve 41 just comes to abut against the wire, it completes the first rotation clockwise to form a knotting point for wire drawing on the spindle tube 2. At this time, the first sleeve 41 is located at the upper left of the spindle tube 2. The wire feeding mechanism 3 retreats to make the wire avoid the first sleeve 41. The first sleeve 41 rotates clockwise to the upper right of the spindle tube 2, and then pushes the second sleeve 42 so that the outer end of the second sleeve 42 is exposed outside the first sleeve 41. At this time, the wire is located on the left side of the second sleeve 42. Then, the control The first sleeve 41 continues to rotate counterclockwise from the previous stopped position, and the second sleeve 42 synchronously follows the first sleeve 41 to rotate counterclockwise, so that the second sleeve 42 is against the wire and rotates counterclockwise until the second sleeve 42 is located at the upper left of the spindle tube 2, and then the second sleeve 42 is retracted, the limiting portion and the end of the first sleeve 41 clamp the wire on the second sleeve 42, and the wire cutting module cuts the wire outside the second sleeve 42 and withdraws, completing the knotting operation.

[0066] It is worth noting that the wire cutting module is also connected to a driving device for driving.

At this time, the second sleeve 42 synchronously rotates counterclockwise with the first sleeve 41, so that the second sleeve 42 rotates counterclockwise against the wire until the second sleeve 42 is located at the upper left of the spindle tube 2.

[0089] S9: The PLC sends a command to the first cylinder according to the set action parameters. The first cylinder receives the command and retracts the second sleeve 42. The limiting portion and the end of the first sleeve 41 clamp the wire on the second sleeve 42.
