[0002] With the development of the packaging industry, higher requirements are placed on packaging paper. Laminating on base paper can protect the base paper and enhance its gloss. The base paper after lamination has a thin and transparent plastic film on its surface, which makes the surface of the base paper smoother and brighter. It not only improves the gloss and fastness of the packaging paper, but also prolongs the service life of the packaging paper. At the same time, the plastic film also plays the role of moisture-proof, water-repellent, anti-fouling, wear-resistant and fold-resistant. Therefore, when processing existing packaging paper, a layer of film is usually set on the surface.

[0003] In order to form a thin film on the surface of the base paper, when processing the packaging paper, it is usually first coated on the surface of the base paper to form a layer of plastic film on the surface of the base paper. The plastic film formed on the surface of the base paper is usually colorless and transparent. According to actual processing needs, the surface of the plastic film on the surface of the base paper is printed, and the printed coating is attached to the surface of the plastic film to give it different patterns and colors, thereby improving the diversity of the packaging paper.

[0046] In order to coat the base paper during transportation, the coating mechanism 3 includes a hot melt component 31 for melting plastic particles and a coating component 32 for coating the base paper with liquid plastic.

[0047] Specifically, the hot melt assembly 31 includes a mobile frame 315, a material storage bin 311, a feed pipe 312 and a hot melt bin 313. The material storage bin 311 and the hot melt bin 313 are both fixedly mounted on the mobile frame 315.

[0050] The driving motor 45 drives the composite roller 41 to rotate, and the driving member 44 drives the sliding frame 43 to move so that the outer wall of the squeezing roller 42 abuts against the outer wall of the composite roller 41, so that when the aluminum foil and the base paper pass through the composite roller 41 and the squeezing roller 42 for transportation, they can be composited.
