The pressing device body 1 is provided with two connecting blocks 6 and they are symmetrically distributed up and down. The pressing device body 1 is fixedly connected with a connecting block 6, and the connecting blocks 6 are provided with three. The pressing device body 1 is fixedly connected with a rotating motor 4 near the connecting block 6. A rotating shaft 10 is movably connected in the pressing device body 1. The rotating motor 4 and the rotating shaft 10 are movably connected through a belt 9. The rotating motor 4 is controlled by an external terminal, and the rotating motor 4 can drive the rotating shaft 10 to rotate through the belt 9. When using this device, the harmful gas generated inside the sandwich panel during the extrusion process will be sucked into the ventilation pipe 14 by the exhaust port 8, and finally discharged into the exhaust pipe of the factory through the exhaust port 5, which will not affect the safety of the workers in the factory and improve the safety of the device.

[0028] Furthermore, two rotating shafts 10 are provided and are respectively located at the two ends of the pressing device body 1 , and a gear 11 is fixedly connected to the rotating shaft 10 . Two gears 11 are provided and are respectively located at the two ends of the rotating shaft 10 , and the rotating shaft 10 can drive the gear 11 to rotate.

[0030] Furthermore, a plurality of pressing plates 2 are provided on the side of the transmission belt 13 away from the gear 11 , and the pressing plates 2 are fixedly connected to the transmission belt 13 , and the upper and lower pressing plates 2 can squeeze the sandwich panel together.

[0031] Furthermore, a hydraulic rod 7 is provided between the top and bottom connecting blocks 6, the hydraulic rod 7 and the connecting block 6 are fixedly connected, and the bottom connecting block 6 is fixedly connected to the base 3 on the side away from the hydraulic rod 7. The hydraulic rod 7 is a commercially available product with its own control component.

[0032] Furthermore, a ventilation pipe 14 is fixedly connected inside the top connecting block 6, and the ventilation pipe 14 is provided with an exhaust port 8 between the pressing device body 1 and the hydraulic rod 7.
