Steam heating and molding device for paper board forming
2014
The utility model discloses a steam heating and molding device for paper board forming. The device comprises a heating plate body provided with a heating inner cavity, the heating inner cavity is glued with a steam passageway coiled back and force adhered to a heating base-plate, an air inlet is arranged in the middle steam passageway at one side of one end of the heating cavity, and a middle steam passageway provided with a steam air inlet as a starting point is divided into upper and lower steam passageways which are oppositely arranged; the two steam passageways are finally and respectively communicated with the side wall steam passageways on the two side walls, and the side walls at the terminals of the side wall steam passageways are respectively provided with steam exhaust ports; the heating plate is in a rectangular shape, the steam passageway of heating inner cavity in the heating plate body is formed by welding a platen with a middle convex part on the heating baseboard, and the section of the passageway between the platen and the heating base-plate is an isosceles triangular steam passageway which is wide in bottom surface of passageway and small in area. The steam heating and molding device has the characteristics of being simple and compact in structure, reasonable in layout, high in paperboard production efficiency and good in energy saving effect, and being capable of quickly promoting the steam temperature in the heating plate, reducing waste paper ratio and the like.
