Background
The Oriented Strand Board (OSB) mainly comprises large pieces of wood shavings, has the characteristics of high mechanical strength, good dimensional stability, excellent environmental protection performance and the like, can be produced automatically on a large scale, is widely applied to manufacturing wood doors, cabinets, wardrobes, wall boards, floors and the like, and has ever-increasing market share. The quality and size of the wood shavings play a decisive role in the performance of the oriented strand board, so that the wood shavings as main raw materials are gradually required to be increased in size, and particularly, the wood shavings are required to be more than 200mm in length and about 25mm in width when being used for the oriented strand board in the aspect of structural materials.
At present, the wood shaving raw materials required by the oriented shaving board are mainly prepared by adopting a two-section shaving preparation technology combining a drum chipper and a flaker in the market, namely, the raw materials are firstly cut into wood chips by the drum chipper and then are processed by a ring flaker to prepare wood shavings. The size of the shavings is mainly determined by the size of the strands processed by the drum chipper. The drum chipper adopted in the two-section preparation technology mainly adopts a 2-4 fly cutter roller structure, and can produce large wood chips with the length dimension of 60-160 mm. The wood chips are processed by a flaker to produce wood shavings with a length below 120 mm. Because the drum chipper adopts a multi-fly cutter roller structure, the length of the wood chips is mainly determined by the feeding speed and the interval time of the adjacent fly cutters passing through the bed cutter successively. Thus, to produce large strands of wood chips having a length of 120mm or more, drum chippers having larger knife roll sizes must be used to produce wood chips having a length of 200mm or more. This not only increased the equipment manufacturing requirement, still increased enterprise's manufacturing cost, is unfavorable for the continuous automated production of production line.
The invention discloses a method for preparing long wood shavings for processing wood plates and a production device thereof (publication number is CN 101722553A).
