A water wheel blade 8 is installed on the inner side of the water inlet pipe 6. A driving motor 9 is installed on one side of the water wheel blade 8. This arrangement can heat the medium-density fiberboard better by liquid, thereby ensuring a better heating effect, which is convenient for subsequent processing.

[0029] Furthermore, the water inlet pipe 6 is configured in an L-shape as a whole, and one end of the water inlet pipe 6 connected to the sealing plate 4 is configured in an elongated strip shape, while the other end of the water inlet pipe 6 is configured in a circular shape. This configuration facilitates uniform heating of the liquid.

[0030] Furthermore, there are multiple water outlet pipes 5, and the ends of the water outlet pipes 5 connected to the sealing plate 4 are arranged in a straight line, and the ends of the water outlet pipes 5 connected to the water inlet pipes 6 are arranged in a ring shape, and the water outlet pipes 5 and the water inlet pipes 6 are connected by a connecting plate 10. This arrangement facilitates the uniform flow of liquid and facilitates heating of the medium-density fiberboard.

[0031] Furthermore, a connection frame 11 is installed on one side of the control box 1 , a hydraulic rod 12 is installed on the inner side of the top end of the connection frame 11 , a top plate 13 is installed on the other end of the hydraulic rod 12 , and the bottom end of the top plate 13 is connected to the upper hot pressing plate 2 .
