Accordingly, a double-layer PVC article 1 shown in fig. 1 was developed, the double-layer PVC article 1 comprising an inner sheet 101 and an outer frame 102 covering the inner sheet 101. The inner plate 101 and the outer frame 102 made of different materials can be selected according to actual production requirements, so that the production cost is reduced.

Therefore, there is a need to develop a production device for realizing the mechanized production operation of the double-layer PVC article.
