[0027] Reference Figure 1-Figure 5 In a preferred embodiment, the bottom end of the protective frame 7 is fixedly connected to the rear column plate 6, the bottom end of the rear column plate 6 is fixedly connected to the top of the supporting base 3, the top of the supporting base 3 is fixedly connected to the auxiliary winding rack 5, the auxiliary winding rack 5 is located above the automatic winding shaft 10, and the automatic winding shaft 10 is provided with a belt 11 near the outside of the connection control board 2, and a rotating shaft 9 is provided on the inner side of the end of the belt 11 away from the automatic winding shaft 10, and the end of the rotating shaft 9 away from the connection control board 2 is fixedly connected to a threaded rotating rod 15, and the rotating shaft 9 is movably connected to the connecting The connecting control panel 2 is on the side away from the winding machine console 1, and an auxiliary guide rod 12 is arranged between the threaded rotating rod 15 and the front frame 4. The auxiliary guide rod 12 is fixedly connected to the side of the connecting control panel 2 away from the winding machine console 1. The outer sides of the threaded rod 1303 and the auxiliary guide rod 12 are movably connected to the inner side of the sliding frame 801, and the end of the auxiliary guide rod 12 away from the connecting control panel 2 is fixedly connected to a fixed frame 16.

[0028] Working principle: When in use, during the first winding, the yarn is released from the yarn roller 14, passes through the bottom of the protective frame 7 (for protection against interference), and then passes through the limiting groove roller 1308 on the inner side of the front frame 4 (to constrain the yarn path), and then the automatic winding shaft 10 starts winding. When the automatic winding shaft 10 rotates, the belt 11 drives the rotating shaft 9, and then drives the threaded rotating rod 15 to rotate. The threaded rotating rod 15 cooperates with the auxiliary guide rod 12 to drive the sliding frame 801 to move axially (similar to a reciprocating yarn guide mechanism) to allow the yarn to be evenly wound on the automatic winding shaft 10. The auxiliary winding frame 5 assists in limiting the position at the top to ensure that the winding shape is regular and then enters between the groove of the groove roller 805 of the yarn connection fixing component 8 and the lower pressure plate 806 (in the initial state, the telescopic electric rod 808 is slightly extended, maintaining light pressure but not clamping); when winding, the drive motor 1301 is started, and the threaded rod 1303 rotates to drive the movable frame 1305 The yarn is moved so that the yarn breaking and cutting component 13 moves synchronously with the winding path. The yarn is passed through the groove of the limit groove roller 1308. The camera 1310 monitors the yarn in real time. The cutting knife 1309 is located above the yarn. If a break is detected, the telescopic driving rod 1307 is shortened, pushing the cutting knife 1309 downward to cut the yarn. After the initial winding is completed, the yarn is cut and retained on the groove roller 805. In the groove, the telescopic electric rod 808 contracts and clamps, the lower pressure plate 806 drives the oblique flexible pressing plate 807 to clamp the yarn, and the compression spring 810 cooperates with the telescopic rod 809 to maintain a stable clamping force to ensure that the yarn is fixed and not loose. When the winding machine is ready for secondary winding, the telescopic electric rod 808 extends, the lower pressure plate 806 moves up, the oblique flexible pressing plate 807 releases the yarn end, and the compression spring 810 resets with the telescopic rod 809 to release the clamping force. The yarn is released from the constraints of the groove roller 805 and the oblique flexible pressing plate 807 and is wound again. It can quickly fix the yarn end to avoid the yarn from being scattered, fix the yarn end and provide a flat cut surface, thereby creating good joint conditions and reducing subsequent yarn breakage, machine jamming, etc. caused by joint problems.
