s4, second laminating, wherein the two layers of materials in the step S3 are conveyed to a laminating component B by a conveying roller A, and when the materials reach the laminating component B, a gold heating lamp tube A positioned above the conveying roller A is started to heat the materials on the conveying roller A; at the moment, a feeding and discharging mechanism is synchronously started to feed and discharge the middle materials, the middle materials reach a feeding and middle material laminating roller through transmission of a transmission device, the feeding and middle materials are wrapped by the feeding and middle material laminating roller and tightly pressed on a feeding and middle material heating roller to heat the feeding and middle materials, the heated feeding and middle materials and the two layers of materials in the step S3 enter a B laminating assembly, and secondary pressing and laminating treatment is carried out at the B laminating assembly to obtain three layers of materials including a bottom material, a middle material and a feeding and middle material;

and S6, embossing, cooling and cutting, wherein the five layers of materials in the step S5 are transmitted to an embossing device through a transmission device, sequentially heated by a bottom surface heating roller, embossed by a bottom pattern roller assembly, cooled by a cooling roller, heated on the surface of the materials by a top surface heating assembly, and then fed into an embossing roller assembly to be embossed, the embossed materials are fed into a cooling device to be cooled and shaped, and finally fed into a cutting device to be cut by the cutting device.
