Conversely, the film roll can be disassembled, which is convenient for the rapid installation and disassembly of the plastic film roll. When hot pressing and laminating through the hot pressing plate 603, while the hydraulic cylinder 602 pushes the hot pressing plate 603 to press down, the rollers 608 on both sides of the hot pressing plate 603 will first contact the film, thereby pulling and unfolding the film at the hot pressing position, so that the plastic film maintains a good tension state to achieve a better film laminating effect and avoid problems such as wrinkling or air bubbles during the aluminum foil laminating process.
