[0034] A first photoelectric switch 208 is provided at the inlet end of the cooling roller 102 close to the first conveying roller 101 to detect whether the rock wool is in place.

[0035] As a typical embodiment, the water inlet pipe 201 and the water return pipe 202 are connected to each roller conveyor through a water distributor 209 and branch water pipes connected thereto.

[0036] A thickness sensor 301 is installed on the transition roller 103 to detect the thickness information of the rock wool board.
