Description

Slab preheating tool for high-density fiberboard production Technical Field The utility model belongs to the technical field of fiberboard production, and particularly relates to a slab preheating tool for high-density fiberboard production. Background The fiber board is an artificial board which is made from wood fiber or other plant fiber as raw material through the procedures of fiber separation, sizing, drying, paving, forming, hot pressing and the like. At present, for the fiberboard subjected to pavement molding, the fiberboard is conveyed to a hot pressing process for hot pressing treatment, so that a fiberboard finished product is prepared, but in the prior art, the temperature of a plate blank subjected to pavement molding is generally in a room temperature condition, so that the temperature of the plate blank is limited to be low when the fiberboard enters hot pressing, the hot pressing molding preparation of the fiberboard can be influenced to a certain extent, and in consideration of the poor heat conduction capability of the raw material of the fiberboard, the hot pressing period of the workpiece preparation process is long, and a large temperature difference exists between the inside and the outside of the plate blank in the hot pressing process, so that the quality and the production capability of a product are directly influenced. Disclosure of utility model Aiming at the technical problems existing in the fiberboard slab processing process, the utility model provides the slab preheating tool for high-density fiberboard production, which has the advantages of reasonable design, simple structure, convenience in processing and capability of realizing the preheating treatment of the to-be-processed board, and the temperature of the upper surface and the lower surface of the slab is improved to a certain extent so as to reduce the temperature difference of the upper surface and the lower surface of the slab, thereby providing preconditions for the production and processing processes of subsequent workpieces, guaranteeing the working processes and effectively meeting the use requirements.
