It should be noted that in this embodiment, the material is first loaded from the working opening A1 on one side, and then unloaded from the working opening A1 on the other side after hot pressing and cooling.

[0021] Specifically, in this embodiment, two groups of support platforms A2 are installed inside the double-station working chamber A. The two groups of support platforms A2 are respectively located at the two working openings A1. The upper end surfaces of the two groups of support platforms A2 are installed with pressure sensors A21. The pressure sensors A21 are used to monitor the weight of the glass fiber raw material transported by the conveying structure C and the hot pressing pressure. It should be noted that in this embodiment, if Figure 2 and Figure 3 As shown, the support platform A2 is located at the working opening A1 and below the conveying structure C.

[0022] Specifically, in the present embodiment, the conveying structure C comprises a conveying chain C1, a plurality of conveying plates C2, a plurality of connecting plates C3 and a plurality of templates C4, wherein the plurality of conveying plates C2 are connected to the conveying chain C1 at intervals, and the plurality of conveying plates C2 are rotatably mounted on the conveying chain C1 in turn through the connecting plates C3, wherein the conveying chain C1 is annular for cyclic operation, and the plurality of templates C4 are rotatably mounted on the conveying plates C2, and the templates C4 are used for feeding the glass fiber raw materials, that is, the glass fiber raw materials are fed to the top of the templates C4.
