High-speed continuous pressing and forming process equipment for biomass artificial plate

Abstract

The invention belongs to the technical field of building material production, and particularly relates to high-speed continuous pressing and forming process equipment for a biomass artificial plate. The equipment comprises a rib plate hanging cage, presses and a plate discharging hanging cage; wherein 2-n of 10-m layers of the presses are used in parallel; and the presses work cooperatively and continuously under the control of a unified computer control center. According to the equipment, dry and withered leaves, branches, abandoned weeds or abandoned plant straws as main raw materials matched with a proper amount of adhesives, mildewproof agents and additives are mixed and spread uniformly, and then are subjected to compression molding; the equipment has the advantages that the equipmentis high in production efficiency, stable in production quality, low in production cost and capable of making full use of abandoned dry leaves and plant straws instead of other wooden or other building materials such as cement, erated blocks, bricks, calcium silicate boards, gypsum boards, various cement fiberboards and the like to manufacture fabricated building materials, the construction is convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a high-speed continuous pressing molding process equipment for biomass man-made boards. Background technique [0002] Most of the existing straw plate production machinery and equipment are single multi-layer presses, and there are also rolling type continuous presses. The multi-layer press was originally used for the production of wood-based panels, such as MDF, particle board and high-density board, etc., and is now used for the production of straw panels. [0003] Everyone knows that whether it is wood-based panels or straw-based panels, the scraps are bonded together with adhesives and quickly solidified under high pressure and high temperature to form a board. Due to the low heat transfer efficiency of straw, the same thickness as MDF Straw wood-based panels need more pressing time to transfer heat to the central part. If the temperature does not reach ...

AI Technical Summary

Problems solved by technology

[0003] Everyone knows that whether it is wood-based panels or straw-based panels, the scraps are bonded together with adhesives and quickly solidified under high pressure and high temperature to form a board. Due to the low heat transfer efficiency of straw, the same thickness as MDF Straw wood-based panels need more pressing time to transfer heat to the central part. If the temperature does not reach a certain height, the adhesive will not cure quickly. If the pressure is released without fully curing the wood-based panels , it will lead to poor bonding in the part that is not fully cured. This part of biomass scrap not only does not make any contribution to the strength of the board, but also has a side effect due to the existence of its rebound force, making the board easy to crack or bubble. Waste products; therefore, the high-speed continuous press molding process equipment for biomass wood-based panels is actually the real professional production equipment for straw panels

[0004] However, it has been found in industrial production that almost all woodworking machinery manufacturing enterprises in my country use a single multi-layer press or multiple single-layer presses. These board production process equipment has serious defects, and single multi-layer press equipment In infinitely increasing the number of layers and the area of ​​the pressing plate, the equipment cost is high, the floor area is large, and the production efficiency is low.
