Specifically, please refer to Fig. 4 and Fig. 5 in combination, the transfer film unwinding mechanism 31 provides the transfer film with the ink pattern to the first transfer mechanism 32, to print the ink pattern on the first primary product, thereby obtaining second primary product. The second-layer preheating lamination mechanism 33 laminates a layer of PVC material on the second primary product to obtain the third primary product. The second transfer mechanism 34 again prints the ink pattern on the transfer film onto the third primary product to obtain the fourth primary product. The three-layer preheating and laminating mechanism 35 laminates a layer of PVC material on the fourth primary product to obtain the fifth primary product.
