[0003] During the production process of new energy modules, packing belts are needed for packing. However, the existing packing belts are usually in rolls and need to be pulled by personnel for unwinding. When the unwinding ends, due to the rotational inertia of the unwinding device, it will continue to unwind, and the extra unwound packing belts may be entangled with each other, affecting the unwinding effect.

Pulling ropes penetrating through the cross - plate and the unwinding box are respectively connected to the two sliders. And fixing frames in an "L" - shaped structure are respectively connected to the bottom sides of the two sliders. Positioning blocks are respectively connected to the opposite sides of the two fixing frames.

[0007] Through the above technical solution, when it is necessary to unwind the strapping tape, the personnel pulls the two pull ropes, and the two pull ropes respectively pull the extrusion springs, and then the extrusion spring pulls the slider, the slider drives the fixed frame, and the fixed frame drives the positioning block. At this time, the strapping tape is pulled, and the strapping tape drives the unwinding drum to rotate, so that the strapping tape is quickly and conveniently unwound from the discharge port. When the unwinding is completed, the pull rope is released, and under the elastic force of the extrusion spring, the slider is pushed to slide along the slide groove, the slider pushes the fixed frame to move, and the fixed frame pushes the positioning blocks to contact the two sides of the unwinding drum, thereby fixing the unwinding drum, causing the unwinding drum to stop rotating, so that the unwinding drum can better unwind the strapping tape.

[0008] The utility model is further configured as follows: one side opposite to the two positioning blocks is respectively connected with a clamping plate, and both sides of the unwinding drum are respectively provided with an annular groove clamped with the clamping plate.

[0009] The utility model is further configured as follows: a magnetic sheet is connected to one side of the two clamping plates opposite to the unwinding drum, and a magnetic strip which is magnetically attracted to the magnetic sheet is arranged in the annular groove.

[0010] The utility model is further configured as follows: the ends of the two pull ropes are commonly connected with a sleeve ring, and the outer side of the unwinding box is fixedly connected with a fixing rod hung with the sleeve ring.

[0013] To sum up, when it is necessary to unwind the strapping tape, the personnel pull the two pull ropes, and the two pull ropes pull the extrusion springs respectively, and then the extrusion spring pulls the slider, the slider drives the fixed frame, and the fixed frame drives the positioning block. At this time, the strapping tape is pulled, and the strapping tape drives the unwinding drum to rotate, so that the strapping tape is quickly and conveniently unwound from the discharge port. When the unwinding is completed, the pull rope is released, and under the elastic force of the extrusion spring, the slider is pushed to slide along the slide groove, the slider pushes the fixed frame to move, and the fixed frame pushes the positioning blocks to contact the two sides of the unwinding drum, thereby fixing the unwinding drum, stopping the unwinding drum from rotating, and allowing the unwinding drum to better unwind the strapping tape.

[0017] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0018] Example: Referring to Figure 1-2 As shown, a packing belt unwinding tool for a new energy module production line includes an unwinding box 1 and a discharge port 2 opened on the unwinding box 1. A support frame 3 in the shape of a "C" is arranged on the inner bottom side of the unwinding box 1. An unwinding shaft 4 is rotatably connected to the support frame 3. An unwinding drum 5 for unwinding the packing belt is sleeved on the unwinding shaft 4. A braking component for braking the unwinding drum 5 is arranged in the unwinding box 1; the braking component includes a horizontal plate 6 installed on the inner top side of the unwinding box 1. A chute 7 is opened on the bottom side of the horizontal plate 6. Compression springs 9 are respectively connected to the inner walls of both sides of the chute 7 along the width direction. Sliders 8 sliding in the chute 7 are respectively arranged on the opposite sides of the two compression springs 9.

Magnetic sheets 15 are connected to the sides of the two clamping plates 14 facing the unwinding drum 5. Magnetic strips 16 magnetically attracted to the magnetic sheets 15 are arranged in the annular grooves 13;

[0019] Specifically, when it is necessary to unwind the packing belt, the operator pulls the two pull ropes 10. The two pull ropes 10 respectively pull the compression springs 9. Then, the compression springs 9 pull the sliders 8. The sliders 8 drive the fixing frames 11. The fixing frames 11 drive the positioning blocks 12.

When the unwinding is completed, the pull ropes 10 are released. Under the elastic force of the compression springs 9, the sliders 8 are pushed to slide in the chute 7. The sliders 8 push the fixing frames 11 to move. The fixing frames 11 push the positioning blocks 12 to abut against both sides of the unwinding drum 5. The clamping plates 14 are inserted into the annular grooves 13. The magnetic sheets 15 and the magnetic strips 16 are magnetically attracted to each other, thereby fixing the unwinding drum 5 and making the unwinding drum 5 stop rotating, so that the unwinding drum 5 can unwind the packing belt better.
