Manufacturing method for producing artificial board with branch strip or shrub tress

Abstract

The invention relates to a method of fabricating artificial board made of tree branch or shrub branch in the fabrication industry of artificial board. Tree branch or shrub branch with the diameter smaller than 20mm is cut into small segments with the length of 40-50mm by trimming machine. Those segments are sent to the thread rolling machine by air-sending system. Water content of small segment of tree branch or shrub branch becomes into 20%-30% and the temperature is 70-80deg.C after heating and moistening by heat. After thread rolling and polishing big material is returned into thread rolling machine again and fiber broken material with satisfaction with process requirement is sent into drying pipe to be dried by hot wind. Namely, fiber preparation segment adopts secondary rolling polishing wind-selecting technology of heating-moistening, rolling-polishing, selecting and rolling-polishing and there is no need of heat polishing. Fiber is separated under normal state. Then artificial board is fabricated by procedures of drying, selecting, sizing, paving, preloading, slab transporting, hot pressing, cooling, edging and sanding so on. The invention makes use of non-forest resource and solves the lack of wood resource. The invention also increases peasant income and possesses huge social benefit. The invention conforms to saving society, cycling economy and sustainable development.

Description

Technical field: [0001] The invention relates to a method for manufacturing wood-based panels (medium- and high-density fiberboards or particle boards) by using tree branches or shrub branches as raw materials in the field of wood-based panel industry. Tree branches or shrub branches The main raw material selected for wood-based panels is tree branches or shrub branches, and the tree branches or shrubs are cut by heating and humidifying - heating and humidifying - rubbing - sorting - rubbing at room temperature and pressure The branches are processed into fiber scraps, and then used to produce wood-based panels through processes such as drying and sorting, sizing, paving, pre-pressing, slab conveying, hot pressing, cooling and trimming, and sanding. Background technique: [0002] From the perspective of the overall available stock of timber resources in my country, it has gradually become scarce and scarce, which will be a threat to the long-term and sustainable development ...
