The material box 21 is fixed on the corresponding conveyer belt 1 and can follow the corresponding conveyer belt 1 to reach above the cavities 41 of the two hot presses 4 at both ends of the corresponding conveyer belt 1.

[0028] The discharging mechanism 3 includes a turntable 31 and a feeding component 32. The turntable 31 is connected to the feeding component 32 and is used to rotate the feeding component 32 so that the discharging ends of the feeding component 32 respectively reach above the material boxes 21 on the two groups of conveyer belts 1. In this embodiment, the turntable 31 is an electric turntable.

[0029] During use, the turntable 31 is used to rotate the feeding component 32 so that the discharging ends of the feeding component 32 respectively reach above the material boxes 21 on the two groups of conveyer belts 1, thereby replenishing materials for each material box 21 in sequence. The conveyer belts 1 respectively drive the corresponding material boxes 21 to move to above the cavities 41 of the hot presses 4 at both ends of the conveyer belts 1. The discharging valve 22 is opened to make the raw materials in the material box 21 fall into the cavity 41. When this device is in use, one discharging mechanism 3 can feed four hot presses 4.
