Description

Technical Field

[0001] The utility model relates to the technical field of paper product processing, in particular to a porous hot press plane. Background Technique

[0002] Conventional hot presses usually only play the roles of heating and applying pressure. Heating makes plastic products melt and then form an ideal shape. However, for materials that need to be dried, such as paper materials, moisture cannot be removed smoothly, resulting in slow drying.

[0003] For example, a paper product hot press forming machine (publication number: CN217922829U) includes: a device base; a forming base fixedly connected to the top of the device base, and a film molding cavity is provided inside the top of the forming base; a connecting plate slidably installed up and down at the bottom of the forming base; a heating plate installed at the bottom of the pressing plate; a fan, the fan unit is installed on the left and right sides of the fixing frame, and springs for resetting the connecting plate are provided on the left and right sides of the bottom of the forming base, and a top plate is fixedly connected to the top of the connecting plate; wherein, the top plate is slidably installed up and down inside the forming base, and the outer surface of the top plate is in close fit with the inner surface of the forming base. This paper product hot press forming machine is convenient for taking out the cardboard after hot pressing and forming through the ejection mechanism, with high processing efficiency, and is also convenient for drying the cardboard after hot pressing, without affecting the processing of cardboard into cartons.

[0004] Based on the retrieval of the above patent and the combination of the equipment in the prior art, it is found that when the above equipment is applied, the cardboard in the forming base is hot pressed and dried by the heating plate. During the hot pressing process of the cardboard, the moisture evaporates slowly. After hot pressing, the fan on the fixing frame is still needed to hot air dry the cardboard, and the drying efficiency of the cardboard is relatively slow. Therefore, we need to propose a porous hot press plane. Content of the Utility Model
