The utility model discloses a sandwich type laminating machine and a linkage laminating machine, and the sandwich type laminating machine can comprise an independent upper box unit which is arranged at the top of the laminating machine; the independent heating plate unit is arranged at the bottom of the laminating machine; a composite unit is arranged between the independent upper box unit and theindependent heating plate unit; the independent upper box unit, the composite unit and the independent heating plate unit are vertically aligned and stacked together, so that laminating cavities areformed between the lower surface of the independent upper box unit and the upper surface of the composite unit and between the lower surface of the composite unit and the upper surface of the independent heating plate unit. According to the sandwich type laminating machine, the space and the material cost can be greatly saved, the temperature distribution is more uniform, the laminating effect isbetter during working, and meanwhile, the working efficiency can be ensured.
