After the adjustment is completed, the nano-composite sheet is placed on the left side of the workbench 1, and the push plate 28 located below the nano-composite sheet is pressed into the interior of the storage tube 25. Then the third motor 29 starts to work and pushes the nano-composite sheet between the upper calendering roller 9 and the lower calendering roller 4 for surface calendering treatment. During the rotation of the upper calendering roller 9 and the lower calendering roller 4, the first scraping component cleans the foreign matter on the surface of the upper calendering roller 9, and the second scraping component cleans the foreign matter on the surface of the lower calendering roller 4.
