It will be more convenient when the foam raw material needs to be moved closely with the pre-expanding device as a whole in the later stage. The top of the bottom plate 1 is fixed with a shell 2 through a mounting seat, and two hydraulic cylinders 3 are fixed on the top of the bottom plate 1. The ejection ends of the two hydraulic cylinders 3 are fixed with a moving frame 4, and the top of the moving frame 4 is fixed with a moving seat 5. The top of the moving seat 5 is fixed with a U-shaped plate 6, and the top of the U-shaped plate 6 is fixed with an axis. The hollow mixing paddle 7 is rotatably connected to the bearing, and sealing rings 15 are fixed inside the through holes opened at the top and bottom of the shell 2. The hollow mixing paddle 7 slides inside the two sealing rings 15, which can enhance the sealing performance of the hollow mixing paddle 7 after being fitted with the shell 2. The bottom end of the hollow mixing paddle 7 passes through the shell 2 and extends below it. The top of the U-shaped plate 6 is rotatably connected to the rotating shaft 8 through the bearing, and the bottom end of the rotating shaft 8 is rotatably connected to the top of the moving seat 5 through the bearing. A driving gear 9 is fixed on the surface of the rotating shaft 8, and a driven gear 10 is fixed on the surface of the hollow mixing paddle 7. The driven gear 10 is connected to the driving gear 9. The gears 9 are meshed and connected, and a heating component 11 for heating the hollow mixing paddle 7 is provided above the bottom plate 1. When using this foam insulation board raw material pre-expanding device, the raw materials and foaming agent can be fed into the interior of the shell 2 through the feeding pipe, and the motor is started to drive the rotating shaft 8 to rotate. Under the cooperation of the driving gear 9 and the driven gear 10, the rotating shaft 8 can be driven to rotate while the hollow mixing paddle 7 is rotated. At this time, the raw materials and foaming agent inside the shell 2 can be stirred, and while stirring, the two hydraulic cylinders 3 can be started to drive the moving frame 4 to move up and down. After the moving frame 4 moves, it can drive The movable seat 5 moves up and down, and after the movable seat 5 moves, it can drive the U-shaped plate 6 to move up and down. At this time, the hollow mixing paddle 7 can be moved up and down while rotating, so that the raw materials and the foaming agent can be fully mixed. Secondly, during the stirring process, the hollow mixing paddle 7 can be heated by the set heating component 11, so that the hollow mixing paddle 7 can stir the raw materials and the foaming agent while uniformly heating the two, so as to improve the production quality of the later products. Finally, when the raw materials are pre-frozen, they can be discharged through the discharge pipe connected to the outer wall of the shell 2.
