[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention ingeniously arranges a first steaming room and a second steaming room with openings facing each other, and both the first steaming room and the second steaming room are provided with a plurality of steaming passages, and any steaming passage contains a plurality of steaming rooms, which can shorten the curing time and reduce the occupied area.

[0020] (2) The present invention ingeniously sets a first lifting mechanism to provide lifting, pushing, pulling and other operations for curing the laminated board, so as to ensure that the laminated board can enter the steaming chamber quickly, accurately and reliably, and after the laminated board is cured, the laminated board can be reliably pulled out of the steaming chamber. In addition, the number of the first winch and the first mold box bearing mechanism of the present invention is the same as the number of columns of the steaming channel, and the position of the first mold box bearing mechanism corresponds to the steaming channel one by one.

[0021] (3) The present invention ingeniously arranges a first mold box push-pull mechanism and a second mold box push-pull mechanism, which can reliably push the laminated panels to be cured into the steaming chamber and pull the laminated panels after curing out of the steaming chamber; at the same time, the present invention ingeniously arranges a third mold box push-pull mechanism and a fourth mold box push-pull mechanism, pulls out the mold box from the upper layer (lower layer) of the double-layer conveying platform, and places it on the second mold box bearing mechanism, and then pushes the mold box into the lower layer (upper layer) of the double-layer conveying platform through the second winch to realize the layer change of the mold box; after the mold box changes layers, it is transported to the first lifting mechanism by the active mold box travel drive mechanism and the driven mold box travel drive mechanism.

[0022] (4) The present invention ingeniously arranges a first steaming room kiln door opening mechanism and a second steaming room kiln door opening mechanism. In order to ensure rapid curing of the composite plate and avoid a large amount of curing heat leakage, a steaming room kiln door that slides up and down is arranged on each steaming room.

Therefore, the present invention uses the steaming room kiln door opening drive motor to drive the steaming room kiln door opening coupling rod to rotate, and uses the gear chain to drive the lifting plate to move up and down, so as to realize the upward lifting of the steaming room kiln door.

[0023] (5) The present invention ingeniously arranges an actuator support frame and a lifting plate, which are arranged to be lowered, retracted and hidden. When the kiln door of the steaming room needs to be opened, the lifting plate is driven to extend by a gear chain and inserted into the lower part of the kiln door of the steaming room to lift the kiln door of the steaming room. The actuator for opening the kiln door of the steaming room of the present invention occupies little space.

[0024] (6) The present invention ingeniously sets up a mold box push-pull mechanism, which uses a push-pull oil rod to push and pull to change the position of the mold box; and the present invention uses a rotating motor to drive the conveying shaft to rotate to change the angle of the hook and pull plate to achieve the hanging and taking operation of the mold box.

[0025] (7) The present invention ingeniously utilizes the cooperation between the mold box push-pull mechanism and the steam-curing room kiln door opening mechanism to realize the opening of the steam-curing room kiln door and the pushing in and pulling out operations of the mold box, thereby ensuring that the upper and lower mold boxes in the steam-curing room move more reliably.

[0026] (8) The present invention is provided with a plurality of active mold box travel driving mechanisms and a plurality of driven mold box travel driving mechanisms on the right side of the first steaming room and on the double-layer conveying platform, so as to ensure more reliable mold box conveying.
