Simultaneously, a high-speed camera 9 captures an image of the wound food packaging film. The image data is transmitted to the control terminal 10, which analyzes and judges the image data in real time. When the position of the food packaging film in the image shifts, the control terminal 10 starts motor 3. The output of motor 3 drives screw 4 to rotate, which in turn moves screw sleeve 5 laterally. Screw sleeve 5 moves U-shaped plate 6 and winding roller 8 laterally, which in turn moves the food packaging film laterally, adjusting its position until it is in the correct position in the image. At this point, a correction process can be performed to achieve the effect of correction.
