At the same time, the upper hot pressing plate is driven downward by the hydraulic cylinder, and the material is pressed down and glued with the lower heating plate. Since the stacked insulating material is heated from top to bottom, the hot pressing efficiency is improved. At the same time, the conveying and stacking effect of the multi-layer material is realized through the multi-layer conveyor belt, which enhances the practicality of the device;

[0014] 2. After hot pressing, the insulating material is rotated 90 degrees by the hot pressing chassis again, so that the opening side of the limit plate faces the single-layer conveyor belt.
