6. According to the invention, through the arrangement of the closed conveying frame, the plate cooling work can be carried out on the formed plate, namely, the plate is completely cooled, and the phenomenon that the extruded plate is deformed after leaving the production line is avoided. When the plate cooling device works, the closed multi-roller tractor pulls plates, the plates are lifted by the rollers of the conveying frame to be conveyed forwards, and meanwhile, the plate cooling process is completed.

7. According to the invention, the closed type shaping table and the closed type multi-roller tractor can move left and right conveniently through the arrangement of the movable guide rail, so that the foaming mold can be maintained conveniently.

8.
