Problems solved by technology

But up to now, due to various reasons, industrialized production and popularization and application have not been successfully realized. One of the important reasons is that the wood bundle unit form of recombined wood causes many difficulties in drying, sizing and paving. Difficult to achieve desired goals
In addition, the raw material processing method of recombined wood is the most energy-intensive raw material processing method. The huge compressive stress generated by the recombined wood bundles under the action of rolling rollers is extremely difficult to eliminate and seriously affects product quality and appearance.

Embodiment 1

[0028] Such as image 3 As shown, on a horizontally placed backing plate 4 with a format size of 700mm×1300mm, the method of directional paving and laying by step-type lamination or brick-wall lamination is adopted, and one or more layers of directional pavement are screened, After straightening, drying, and gluing, make a wood screw rod 2 of the same specification. The size specification of the wood screw rod is B×H×L=(0.5~3.0)mm×(0.5~3.0)mm×(50~500)mm ,Such as figure 2 . The so-called stepped laminated directional pavement refers to firstly orienting along the width direction of the slab, the length direction of the wood screw rods is parallel to the length direction of the slab, laying a row of wood screw rods neatly and evenly, and then moving half the wood screw rods to the length direction of the slab Rod length distance, and then lay a row of wood screw rods neatly and evenly along the width direction of the slab, and then repeat the above process until one or more l...

Embodiment 2

[0031] Such as figure 2 , image 3 , Figure 4 , Figure 5 , Figure 8As shown, on the backing plate 4 placed at the bottom of a molded box 8 of length × width × height = 1300mm × 700mm × 600mm, the wood screw rod 2 of the same specification will be made after screening, straightening, drying and gluing. The directional pavement and billet assembly method of stepped lamination or brick wall lamination is oriented and quantitatively positioned and paved layer by layer to a height of 600mm, and then sent to the upper platen 5 of the single-layer upper-press cold press equipped with a die 9 On the lower platen 6, after cold pressing (pressure F is 5×10 6 Pa, the cold pressing time is 30h; or the pressure F is 10×10 6 Pa, the cold pressing time is 15h; or the pressure F is 8×10 6 Pa, cold pressing time is 24h), pressure relief, and demoulding to make wood wool molded material 10, the length×width of wood wool molded material 10=1300mm×700mm, the height dimension is determin...

Abstract

The invention discloses a scrimber comprising wood wool rod units and a manufacturing method. Wood wool rods with identical specifications are directionally laid on a cushion plate in a stepped stacking mode or a brick wall type stacking mode after being selected, straightened, dried and glued, then the cushion plate is conveyed into a lower mold of an opening type mold mounted on a hot press, and single wood wool slabs are manufactured by means of thickness limiting mold pressing, pressure relieving, mold releasing and sanding processing; or the wood wool rods are directionally laid in a stepped stacking mode or a brick wall type stacking mode on the cushion plate placed at the bottom of a mold pressing box, and a wood wool mold pressing material is manufactured by means of mold pressing, pressure relieving and mold releasing. The scrimber has the advantages that characteristics of natural solid wood are kept, gluing area and gluing strength are improved, the problem that products including plywood, technical wood and the like need to be formed by single plates manufactured by means of rotationally cutting straight logs of large-diameter tree trunks is solved, and the problem of strain on resources and resource exhaustion of raw materials for producing the man-made board products is also solved.

Description

technical field [0001] The invention relates to a recombined wood and a preparation method thereof, in particular to a recombined wood with a wood screw rod as a unit and a preparation method thereof. Background technique [0002] Wood-based panels process wood (or non-wood plant fibers) into various small units (veneer, fiber, shavings, etc.), and then combine these small units to make plywood, fiberboard, particleboard, etc. Small units of the same type are not consistent in shape or size as individuals, and also destroy the original macroscopic or microstructural structure (such as fibers) of wood. The fiber directions of solid wood are arranged in an orderly manner but randomly combined, and the performance indicators and appearance of various wood-based panels made are very different from solid wood. At the same time, the processing of these small units has the problems of high energy consumption and dust pollution; the shape of fibers and shavings is small and the spe...
