Plate core of artificial structural plate and manufacturing method thereof

Abstract

The invention provides a plate core of an artificial structural plate. The plate core of the artificial structural plate comprises a plurality of core strip units, the core strip units are provided with multi-layer structures in the length direction of the plate core, each core strip unit at least comprises a double-transverse pressure-bearing body which extends in the length direction of the plate core and an inclined pulling structure which is obliquely arranged relative to the double-transverse pressure-bearing body, each core strip unit sequentially comprises the double-transverse pressurebearing body and the inclined pulling structure in the length direction of the plate core, and is formed by stacking and bonding the double-transverse pressure bearing body and the inclined pulling structure, and the core plate is formed by repeatedly stacking the core strip units in the length direction of the plate core. According to the plate core of the artificial structural plate, the strength of the artificial plate can be effectively improved, the bearing capacity of the artificial plate is improved, the using amount of an adhesive is reduced, and the effects of being green and environment-friendly are achieved. On the basis, the invention further provides a manufacturing method of the plate core. The method can be used for mechanical operation, and is simple in process and high inproduction efficiency.

Description

technical field [0001] The invention relates to the field of man-made board manufacture, in particular to a board core of a man-made structural board and a processing method for the board core. Background technique [0002] Due to the shortage of timber resources and the high price of solid wood, wood-based panels have emerged as the times require, and are widely used as panel materials for furniture, wooden doors, floors and architectural decoration. At present, the commonly used wood-based panels are mostly particle boards, fiberboards, plywood, and laminated materials. The above-mentioned wood-based panels are based on shavings, fibers, and veneers, etc., and are formed by pressing high temperature and high pressure with adhesives. , the production cost is low, but there are also many defects: the product is heavy and inconvenient to carry; the finished board has low structural strength; Production requirements. [0003] In view of this, how to improve the strength of w...

Problems solved by technology

At present, the commonly used wood-based panels are mostly particle boards, fiberboards, plywood, and laminated materials. The above-mentioned wood-based panels are based on shavings, fibers, and veneers, etc., and are formed by pressing high temperature and high pressure with adhesives. , the production cost is low, but there are also many defects: the product is heavy and inconvenient to carry; the finished board has low structural strength; Production requirements

The formation of the board is only by cutting grooves on the side of the square wood block to extend into a slab. This structure is relatively simple. When it is subjected to a relatively complicated external force, because there is no other structure to match the cut groove structure, its The force cannot be balanced, resulting in low strength of the slab and easy damage

[0004] Chinese patent CN202021653U discloses a technology called grid hollow-core wood-based panels, which solves the problems of high density and large internal stress of the existing wood-based panels, but still has problems such as narrow range of raw materials and low structural strength

Chinese patent CN104070567B discloses a structural plate, its core, and a processing method for the core, specifically disclosing a structural plate core and a processing method with large bearing capacity and high structural rigidity, but the processing method is not convenient for mechanized operations. Laborious and laborious, low production efficiency

Chinese patent CN202021651U discloses a multifunctional flame-retardant wood-based panel. Its technical solution is to coat the upper and lower flame-retardant layers on the upper and lower surfaces of the wooden center layer, and cover the panels on the upper and lower flame-retardant layers. Solved the flame retardant problem of wood-based panels, but there is still the problem of low structural strength of wood-based panels
