A drive shaft 3-2 is arranged at the output end of the output motor 3-1, and the drive shaft 3-2 is inserted into the machine stand 1. A drive disk 3-3 is arranged at the end of the drive shaft 3-2. A sliding groove 3-4 is opened on the drive disk 3-3, and a reel 3-5 is inserted in the sliding groove 3-4. Both ends of the reel 3-5 extend out of the sliding groove 3-4. A limit block 3-6 is fixedly arranged on the machine stand 1, and one end of the reel 3-5 is embedded in the limit block 3-6.

[0034] In this embodiment, the winding yarn is inserted on the reel 3-5, and after the winding yarns are inserted on the three driving shafts 3-2, any winding yarn can be switched at will after the output motor 3-1 rotates to drive the driving disk 3-3, and multiple winding yarns can be installed each time, which reduces the frequency of replacing the winding yarn. When the output motor 3-1 drives the driving disk 3-3 to rotate, the winding yarn 3-5 located above will slide onto the limit block 3-6 for limit, and the sleeve bearing on the winding yarn 3-5 will contact the limit block 3-6, and the winding yarn 3-5 will rotate in the limit block 3-6. After the current winding yarn 3-5 is used, the driving disk 3-3 is rotated to replace another winding yarn 3-5.

[0035] Specifically, there are two machine stands 1, a linkage shaft 3-7 is provided between the two machine stands 1, and the linkage shaft 3-7 is connected to the machine stands 1 via a bearing.

[0036] In this embodiment, the linkage shaft 3-7 plays an auxiliary feeding role in the yarn winding and feeding process, making the yarn winding and feeding more stable.

[0037] Furthermore, the leveling processing assembly 4 includes a fixed frame 4-1, which is arranged between the two machine stands 1. The inner wall of the fixed frame 4-1 is provided with a No. 1 hot compress sheet 4-2 and a No. 2 hot compress sheet 4-3.

[0043] When it is necessary to load the reel 3-5, the yarn is inserted on the reel 3-5. After the three driving shafts 3-2 are all inserted with the yarn, the output motor 3-1 rotates to drive the driving disk 3-3, and any yarn can be switched at will. Multiple yarns can be installed each time, which reduces the frequency of replacing the yarns. When the output motor 3-1 drives the driving disk 3-3 to rotate, the reel 3-5 located above will slide onto the limit block 3-6 for limit, and the sleeve bearing on the reel 3-5 contacts with the limit block 3-6, and the reel 3-5 rotates in the limit block 3-6. After the current reel 3-5 is used, the driving disk 3-3 is rotated to replace another reel 3-5. The yarn passes through the gap between the No. 1 hot compress sheet 4-2 and the No. 2 hot compress sheet 4-3 on the fixed frame 4-1, which can heat the yarn and smooth it, and the gap 4-4 makes it more convenient to feed the yarn.
