The film roll 7 is pretreated by the flexible roller 10 to make the film roll 7 pre-attached to the surface of the photovoltaic glass plate 2. When the attachment surface of the photovoltaic glass plate 2 and the film roll 7 contacts the inflatable roller pressure cylinder 16, due to the rubber material of the inflatable roller pressure cylinder 16, it has a certain plasticity, and the spring 24 generates a spring force, so that the movable block 13 is always subjected to downward pressure, so that the inflatable roller pressure cylinder 16 can contact the film roll 7 more closely.
