The thread pulling mechanism comprises a first main gear 17, a first driven gear 18 meshed with the first main gear 17, and two first toothed rollers 19. The first main gear 17 and the first driven gear 18 are fixedly connected with the first toothed rollers 19 through a connecting column 20. The two first toothed rollers 19 are arranged in contact and in front of the fixed panel 11, and are used to pull out the remaining thread in the bobbin 13. The roughening mechanism comprises a second main gear 21, a second driven gear 22 meshed with the second main gear 21, and two second toothed rollers 23. The second main gear 21 and the second driven gear 22 are fixedly connected with the second toothed rollers 23 through the connecting column 20. The two second toothed rollers 23 are driven to open and close by the second main gear 21 and the second driven gear 22, so as to roughen the thread end, which is convenient for threading the thread into the bobbin 13. Preferably, other devices can also be used to drive the toothed rollers to rotate, such as synchronous belts and other devices that can realize rotation.

[0035] A thread collecting mechanism 24 is arranged below the first toothed rollers 19 and the second toothed rollers 23. The thread collecting mechanism 24 is used to receive the waste thread generated by the thread pulling mechanism and the roughening mechanism, so as to prevent the waste thread from winding into the device and causing the device to fail to operate. The thread collecting mechanism 24 comprises a thread collecting box 241 and a dust collection gun 242 in communication with the thread collecting box 241.

[0036] A blowing mechanism is arranged above the first toothed rollers 19, which is used to blow the thread in the bobbin 13 into the middle of the two first toothed rollers 19, so as to prevent the thread from floating into other places and causing the thread to be unable to be pulled out. The blowing mechanism comprises a blowing piece 25 and a gas sending piece 26 connected with the blowing piece 25.

The line blowing assembly is installed on the fixed panel 11 and comprises a blowing port 41 and a swing cylinder 42 fixedly connected with the blowing port 41. The swing cylinder 42 penetrates through the fixed panel 11 and drives the blowing port 41 to move between the winding device and the roughening mechanism. In one working process, the swing cylinder 42 first drives the blowing port 41 to move above the roughening mechanism to roughen the line so as to better penetrate into the bobbin 13. After the roughening is completed, the swing cylinder 42 drives the blowing port 41 to move to the winding device to align the line inlet of the bobbin 13 to perform the winding work. The line feeding assembly is fixedly installed on the rack 10 and connected with the line blowing assembly through a line. The line feeding assembly comprises a line disc 43, a winding part 44, a line moving assembly and a detection mechanism.

The sensor is arranged at the rotating part 48 behind the fixed plate 45. When the line is wound, the rotating part 48 is in a rotating state. Then, the sensor senses that the rotating part 48 rotates, which indicates that the line disc 43 has the line and works normally. When the line in the line disc 43 is used up, the rotating part 48 stops rotating. After the sensor senses the stop, an alarm is given to indicate that the line in the line disc 43 is used up and manual line feeding is needed.

[0040] Preferably, the fixed panel 11 is further provided with a waiting position 49. When the sewing machine 12 still has the bobbin 13, the waiting position 49 is used to place the bobbin 13 after the threading is completed.
