The deviation correction mechanism 6 can keep the protective film in the same straight line when it moves to avoid the deviation of the protective film. When the protective film deviates, the movable plate 63 is pushed to move by the electric push rod 62, so that the squeezing roller 68 moves, and the position of the protective film is adjusted so that the protective film is in the same position on the winding roller.

[0027] Reference Figure 3 , 4 As shown, the deviation correction mechanism 6 also includes a measuring plate 69, an infrared measuring device 610 and a controller 611.

When the protective film moves, the infrared measuring device 610 detects the deviation of the protective film, and further feeds back to the controller 611.
