Abstract

The invention discloses high-moisture-proof high-density fiberboard equipment and a manufacturing method thereof, and belongs to the technical field of board preparation. The high-moisture-proof high-density fiberboard equipment comprises an airflow spreading machine, a pre-pressing machine, a cutting machine, a microwave preheating device, a steam injection preheating device, a hot pressing machine, a second friction roller shaft conveyor and a clamping roller conveyor which are sequentially and linearly arranged in the board blank conveying direction and connected end to end. A trimming device is arranged on the second friction roller shaft conveyor. According to the high-moisture-proof high-density fiberboard equipment and the manufacturing method thereof, before hot pressing, a plate blank is heated to a certain temperature through the microwave preheating device, so that cracking caused by rapid temperature rise of the plate blank is avoided; the thermoplasticity of the plate blank is increased through the steam injection preheating device, the plate blank is heated and softened, the thermoplasticity is increased, the rebound force is reduced, the plate blank is easily pressed to the specified thickness, and manufacturing of a high-density fiberboard is achieved; and a row of through holes are reserved in the center of the plate blank, so that the plate blank is heated uniformly, and the center temperature of the plate blank is increased.

Description

technical field [0001] The invention relates to the technical field of plate preparation, in particular to high moisture-proof high-density fiberboard equipment and a manufacturing method thereof. Background technique [0002] The fiberboard currently sold on the market is made of logs, harvesting, processing residues, and non-woody plant fiber raw materials. After slicing, cooking, fiber separation, and drying, urea-formaldehyde resin or other applicable adhesives are applied, and then hot-pressed. Made of a man-made board. [0003] Due to its wide source of raw materials and easy secondary processing, fiberboard has become the most representative type of wood-based panel in my country. In the process of fiberboard manufacturing, there are many factors that affect product quality, including the quality of raw materials and the shape of fibers after heat grinding. , fiber moisture content after drying, adhesive quality and sizing amount, hot pressing process, etc. [0004] ...
