The thread wound on the bobbin is led from the thread on the large bobbin through a bobbin winding device and wound on the bobbin. In the existing bobbin winding device, the bobbin, the guiding member and the bobbin are generally not on the same line. The thread on the bobbin will have multiple bends when passing through the guiding member to the bobbin. In this way, the tension on the bobbin during the winding process will be relatively large. When the thread is relatively thin, the thread is easily broken, and at the same time, phenomena such as knotting or entanglement are likely to occur. At the same time, the winding speed cannot be adjusted, and it is easy to have the situation of too loose or too tight winding. After the winding is completed, it still needs to be manually cut, and the operation efficiency is low.

[0027] A clamping structure matching with the bobbin 15 is arranged at the position where the bobbin 15 is installed on the bobbin fixing shaft 14.
[0028] This application changes the structural form of the existing traditional winding device. The winding speed can be adjusted as needed. The positions of the bobbin, the thread clamp, and the bobbin core are on the same line. Knotting is avoided during the unwinding of the bobbin and the winding of the bobbin core. At the same time, after winding is completed, it can be automatically cut without manually cutting the thread with scissors, saving time and effort. The specific structure of this application is as follows:
[0029] On one side of the upper surface of the base 1, a support frame 2 is fixed. The support frame 2 is used to install and place the mounting shaft of the bobbin 3 and plays a supporting role. The support frame 2 includes a central shaft 21, support columns 22, and a spring clip 23. Two equal-height support columns 22 are vertically installed on the base 1. The central shaft 21 is installed on the support columns 22. The central shaft 21 is used to fit into the bobbin 3. At the same time, the bobbin 3 can rotate around the central shaft 21 during the unwinding process. One end of the central shaft 21 is hinged to the upper end of one of the support columns 22, and the spring clip 23 is installed at the upper end of the other support column 22. The other end of the central shaft 21 is clamped into the spring clip 23. The central shaft 21 does not rotate around its axis, and the outer surface of the central shaft 21 is smooth. The end of the central shaft 21 clamped into the spring clip 23 can be taken out upward and flipped upward around the hinge shaft at the other end of the central shaft 21, facilitating the removal and replacement of the bobbin 3.
[0030] On the other side of the upper surface of the base 1, a motor 12 is installed. The motor 12 can be a reduction motor or a general motor. The motor 12 is connected to a speed control switch. The speed control switch is a speed control knob 18. The speed control knob 18 is installed on the outside of the base 1 and is connected to the power supply circuit of the motor 12. By adjusting the speed control knob 18, the speed of the motor 12 can be conveniently adjusted. A clamping chuck 13 is coaxially fixed to the output shaft of the motor 12. A bobbin core fixing shaft 14 is clamped and fixed at the center of the clamping chuck 13. The motor 12 drives the bobbin core fixing shaft 14 to rotate through the clamping chuck 13. The bobbin core fixing shaft 14 and the output shaft of the motor 12 can also be coaxially fixedly connected through a coupling.
[0031] At the outer end of the bobbin core fixing shaft 14, a clamping member coaxially connected to the bobbin core 15 is provided. The clamping member is used to realize the connection and fixation between the shaft hole of the bobbin core 15. The clamping member can adopt a conical structure. The outer end of the bobbin core fixing shaft 14 can also be provided with a notch groove along the axial direction, so that the outer end of the shaft forms a fork. The fork part is slightly opened outward and has a certain elasticity, facilitating the shaft hole of the bobbin core 15 to be stuck on the forked end to achieve fixation.
[0032] A tool holder 9 is respectively installed between the support frame 2 and the motor 12. A central through hole 10 is formed in the tool holder 9. A blade 8 is installed in the shearing hole. The blade 8 is connected to a telescopic structure. When the telescopic structure acts, the wire penetrating into the central through hole 10 can be quickly cut off. The telescopic structure can have various structural forms. When an electromagnetic telescopic device is adopted, it mainly includes an electromagnetic telescopic member 6 and a push rod 7. The electromagnetic telescopic member 6 is installed on the base 1 or the support 4. The moving end of the electromagnetic telescopic member 6 is connected to one end of the push rod 7. The other end of the push rod 7 is connected to the blade 8. When the electromagnetic telescopic member 6 extends outwards, the push rod 7 drives the blade 8 to achieve shearing. To improve safety, a protective cover 11 is sleeved on the tool holder 9. Through holes are respectively formed on both sides of the protective cover 11. The through holes on both sides of the protective cover 11 are communicated with the central through hole 10.
[0033] In addition, a support 4 is also installed between the support frame 2 and the motor 12 in this application. A wire clamp 5 is installed on the support 4. The wire clamp 5 can play a role in guiding the wire. At the same time, the wire clamp 5 can also adjust the tightness, so as to adjust the tightness and uniformity of winding. The wire unwinding of the bobbin 3 and the winding of the bobbin core 15 in this application are automatically carried out. The winding process is smooth and can be automatically cut off, which is very convenient to use.
[0034] The above content is a further detailed description of this application in combination with specific implementation manners. It cannot be considered that the specific implementation of this application is only limited to these descriptions. For those of ordinary skill in the technical field to which this application belongs, without departing from the concept of this application, this application will have various simple replacements, improvements and changes. All the simple replacements, improvements and changes made should be regarded as belonging to the protection scope of this application.
