Start the first electric push rod 10, and retract the telescopic rod of the first electric push rod 10 to drive the lifting frame 11 to move. When the lifting frame 11 moves, the film can be tensioned on the first guide roller 14 and the second guide roller 22. When the film is tensioned, the tension sensor 12 can detect the force exerted on the first guide roller 14 when the film is tensioned. The data detected by the tension sensor 12 can be transmitted to the control panel 15. While the control panel 15 can display the detected data, the control panel 15 can control the first electric push rod 10 to stop pulling the first guide roller 14, preventing the film from breaking or deforming due to excessive tension.

By the operation of the first driving motor 7, the unwinding roller 4 and the winding roller 19 can be driven to rotate. When the unwinding roller 4 rotates, it can unwind the film, and the winding roller 19 can wind the film. By the third electric push rod 23, the adjusting frame 24 can be pushed, so that the adjusting frame 24 drives the third guide roller 26 to approach the second guide roller 22. Through the cooperation of the third guide roller 26 and the second guide roller 22, the film can be positioned, making the film stable during transportation. When the third guide roller 26 approaches the second guide roller 22, the second driving motor 27 can drive the third guide roller 26 to rotate, so that the cutting blade 28 driven by the third guide roller 26 rotates, enabling the cutting blade 28 to trim the edge of the film. The film after edge trimming can be wound on the winding roller 19.
