[0002] The full name of melamine board is melamine impregnated film paper veneer artificial board. Melamine board is made by soaking paper with different colors or textures in melamine resin adhesive, then drying it to a certain degree of solidification, laying it on the surface of particleboard, moisture-proof board, medium-density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard, and then hot pressing it to make a decorative board.

[0003] During the manufacturing process of melamine board, the base material and the surface paper need to be laid out overlappingly, and then the embossing of the base material and the printed pattern of the paper need to be completely overlapped under the operation of the hot press. This type of equipment can refer to a hot press disclosed in Chinese patent publication number CN210705200U, which includes a hot press body and a connecting rod mechanism. The hot press body includes an upper mold that can move up and down and a fixed lower mold.
