[0022] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The embodiment of the utility model provides an unwinding control device for an unwinding machine, comprising an installation panel 1, a driving motor 2 is provided on the rear side of the installation panel 1, a spinning disc 3 is provided on the front side of the installation panel 1, a spinning drive shaft 4 is provided at the center of the spinning disc 3, one end of the spinning drive shaft 4 passes through the installation panel 1 and extends to the rear side of the installation panel 1, and the end of the spinning drive shaft 4 is connected to a driving gear 5, which is in transmission connection with the driving gear 5 and the driving motor 2;

[0023] Among them, the front side of the installation panel 1 is also connected to the first wire assembly 6, the second wire assembly 7 and the tension adjustment assembly 8. The tension adjustment assembly 8 includes a tension shaft 9. The tension shaft 9 extends from the front side of the installation panel 1 to the rear side of the installation panel 1. The end of the tension shaft 9 is connected to a tension sensor 10. The tension sensor 10 is used to monitor the tension of the tension adjustment assembly 8 to control the unwinding speed.

[0024] This embodiment also includes a main controller 11 and a human-machine interface touch screen 12. The main controller 11 is fixed to the rear side of the mounting panel 1, and the human-machine interface touch screen 12 is fixed to the front side of the mounting panel 1. The human-machine interface touch screen 12 and the main controller 11 are electrically connected. The human-machine interface touch screen 12 is used to set the parameters of the unwinding control device of the unwinder and can also display the real-time unwinding speed or tension value. In addition, the drive motor 2 and the main controller 11 are electrically connected, and the tension sensor 10 and the main controller 11 are electrically connected; the main controller 11 is used to control the operating speed of the drive motor 2 based on the tension monitored by the tension sensor 10.

[0025] In this embodiment, the first wire assembly 6 includes a first fixed shaft 13, the end of the first fixed shaft 13 is connected to the first tensioning wheel 14, the first fixed shaft 13 is also connected to the wire rack 15, the wire rack 15 extends to the side of the first tensioning wheel 14, and the wire rack 15 is formed with a wire hole 16; the second wire assembly 7 includes a second fixed shaft 17, the end of the second fixed shaft 17 is connected to the second tensioning wheel 18; the tension adjustment assembly 8 also includes a transfer rod 19, the transfer rod 19 is L-shaped, one end of the transfer rod 19 is connected to the tension wheel 20, and the other end of the transfer rod 19 passes through the tension shaft 9.

[0026] Specifically, a single-spindle yarn reel is secured by a spinning disc 3. A drive motor 2 drives a drive gear 5 via a transmission belt, which in turn drives the spinning disc 3 via a spinning drive shaft 4. The yarn unwound from the reel passes around the second drawing wheel 18, then through the tension wheel 20 and around the first drawing wheel 14, before being drawn out through a guide hole 16 adjacent to the first drawing wheel 14. The second drawing wheel 18 is capable of rotating relative to the second fixed shaft 17, the tension wheel 20 is capable of rotating via the tension wheel 20, and the first drawing wheel 14 is capable of rotating relative to the first fixed shaft 13, thereby unwinding the yarn from the single-spindle yarn reel.

[0027] During the unwinding process, the tension sensor 10 at the end of the tension shaft 9 monitors the tension of the tension adjustment assembly 8. The tension sensor 10 detects changes in the main machine speed and provides feedback to the single-spindle controller for online adjustment of the winding speed, achieving synchronization with the main machine's linear speed and thus controlling the unwinding speed. This ensures constant tension unwinding and ensures consistent tension during reel rewinding. The position of the adapter rod 19 can be set arbitrarily, simplifying operation. Furthermore, it can be used with high-speed wire drawing units, achieving unwinding speeds of up to 120 m / min, compared to conventional unwinding speeds of less than 20 m / min.

[0028] In a possible embodiment, the first spool 14, the tension wheel 20, and the second spool 18 are distributed in a triangle, and the first spool 14, the tension wheel 20, the second spool 18, and the spinning disk 3 are in parallel, thereby ensuring the unwinding stability of the single-spindle silk reel during the unwinding process.

[0029] In one possible embodiment, a limiting post 21 is provided on the mounting panel 1 and is located on one side of the transfer rod 19. The limiting post 21 can limit the position of the transfer rod 19 of the tension adjustment assembly 8, limiting the excessive rotation of the transfer rod 19 from interfering with the spinning disc 3, while ensuring that the tension wheel 20 is located in the middle area between the first and second tensioning wheels 14, 18.

[0030] In one possible embodiment, a rolling bearing 22 is provided at the contact point between the tension shaft 9 and the mounting panel 1; a sleeve 23 is connected to the tension shaft 9 at the rear side of the mounting panel 1. The rolling bearing 22 enables the tension shaft 9 to rotate relative to the mounting panel 1, and the sleeve 23 protects the tension shaft 9.

[0031] In a possible embodiment, the drive motor 2 is directly driven by a brushless DC motor: each spindle is equipped with a brushless DC motor directly driven, which saves 30% of electricity compared to AC inverter drive, thus reducing electricity costs for end users.

[0032] In summary, the rear side of the mounting panel 1 of the present invention is provided with a drive motor 2, the front side of the mounting panel 1 is provided with a spinning disk 3, the center of the spinning disk 3 is provided with a spinning drive shaft 4, one end of the spinning drive shaft 4 extends through the mounting panel 1 to the rear side of the mounting panel 1, the end of the spinning drive shaft 4 is connected to a driving gear 5, and the driving gear 5 and the driving motor 2 are connected in a transmission manner; the front side of the mounting panel 1 is also connected to a first wire assembly 6, a second wire assembly 7 and a tension adjustment assembly 8, the tension adjustment assembly 8 includes a tension shaft 9, the tension shaft 9 extends from the front side of the mounting panel 1 to the rear side of the mounting panel 1, the end of the tension shaft 9 is connected to a tension sensor 10, and the tension sensor 10 is used to monitor the tension of the tension adjustment assembly 8 to control the unwinding speed. The single spindle silk reel is fixed by the spinning disk 3, the drive motor 2 drives the drive gear 5 through the transmission belt, and the drive gear 5 drives the spinning disk 3 to operate through the spinning drive shaft 4. The silk thread released from the silk reel passes around the second tensioning wheel 18, then passes around the first tensioning wheel 14 through the tension wheel 20, and is finally led out from the wire hole 16 next to the first tensioning wheel 14. Among them, the second tensioning wheel 18 can rotate relative to the second fixed shaft 17, the tension wheel 20 can rotate through the tension wheel 20, and the first tensioning wheel 14 can rotate relative to the first fixed shaft 13, thereby realizing the silk thread unwinding of the single-spindle silk reel. During the unwinding process, the tension sensor 10 at the end of the tension shaft 9 can monitor the tension of the tension adjustment component 8. The tension sensor 10 detects the change in the main machine speed and feeds back to the single-spindle controller to adjust the winding speed online, so as to achieve synchronization with the main machine line speed and control the unwinding speed, so as to achieve constant tension unwinding and ensure the consistency of tightness when the reel is wound. The utility model can adjust the unwinding speed in real time, thereby ensuring that the unwinding tension is constant, and the reel forming is consistent and uniform in tightness, meeting user needs.
