Cooling system is one of the most important equipment of the sandwich panel production line. It is used for those panels which just come out from the double belt and the core parts of which are not completely solidified even still in a reaction. We do this is to avoid a series of problems caused by the non-uniform heat dissipating of the sandwich panel which stack immediately.

The main beams of the cooling system are all processed by gantry, and connected by bolts positioning keys. Our company’s cooling bed has the characteristics of working smoothly and good rigidity, and can load the PU panels with thickness of 200mm. It adopts servo- control system to make three panels in and out at the same time to achieve the biggest utilization rate of the cooling bed. The panels move from transition roller path to the specified position of the up cooling bed roller table by rollers. The lift goes up, and the synchronous belt transfers panels to the bottom of fork, main shaft controls panel turning 90 degree. When panels move down, first the fork make the panels turn to the cooling roller path, then the moving mechanism transfer panels away from the fork, and convey them to next process through by transition roller path.

1)Main motor power: 4kW

2)Size of panel: thickness 20-200mm, width 600-1200mm, single unit:2-7.5m,double unit:2-15m, three unit:2-27m

3)Conveyor roller speed (covered with rubber): 2-30m/min

4)Rotate speed of cooling bed: 1-1.4m/min

5)Motor power of cooling bed: 7.5kw*2

6)Dimension (length×width×height）: longest work piece 15000mm

7)Width of fork: 360mm

8)Supporting plate covered with plastic to avoid scratching on the panels

9)Controlling: PLC, linkage with other device by auto or manual

10)Conveying chain: to be custom made

11)The ringfeder can be adjusted to ensure synchronization with supporting plate.

12)The cooling time of each panel is 90 min. It’s basic on the main machine speed of 6m/min and the panel length of 12m.
