The invention provides a stereo coating machine. The stereo coating machine comprises a coating device, a cutting device and a thermal contraction device, wherein the coating device comprises a feeding mechanism and a coating mechanism; the coating mechanism receives plastic films for coating provided by the feeding mechanism, and coats a product; the cutting device comprises a first cutting mechanism and a second cutting mechanism which are sequentially arranged; the first cutting mechanism comprises first corner cutting heat sealing cutters positioned on the front and back sides of the product, and a first bottom cutter and a first heat sealing cutter which are positioned on the upper and lower sides of the product; the second cutting mechanism comprises second corner cutting heat sealing cutters positioned on the front and back sides of the product, and a second bottom cutter and a second heat sealing cutter which are positioned on the upper and lower sides of the product; and the thermal contraction device is positioned in the downstream position of the cutting device and heats the cut films. According to the stereo coating machine, the plastic films subjected to thermal contraction can tightly fit packaging boxes of the product, bulges are avoided, and the aesthetic property and the fitting property of the internal packaging films are maintained.
