Abstract

A method for manufacturing wooden board includes rotary cutting the log to obtains heets, arranging the sheets by a certain order, making rectangular plywood, sawing the rectangular plywood diagonally to obtain two triangular plywood blocks, splicing tham to form a whole in parallelogram shape, splitting the parallelogram board into strips by saw, and splicing the strips to obtain needed board, and features high productivity.

Description

A kind of manufacture method of wooden boards

The present invention relates to a kind of manufacture method of pure wooden boards, mainly is by gummed and the method for tiltedly cuing open the pure wooden boards of processing that combines.

Now in the building material industry, the processing of products such as wooden furniture board, wall slab, big specification floor is that raw material timber is sawn into several laths, gluing was bonding again after every block of lath planed one by one forms, sometimes need just can finish for tens times even tens times, and the specification of lath is more little, and the number of times that repeats to process is just many more, and loss is big more, production efficiency is reduced significantly, can not adapt to requirements of large-scale production.Simultaneously, can only see the texture of trees on tangential section or radial longitudinal section from the surface of this series products, and wooden more beautiful textured pattern can't show.

A kind of processing method of solid plank integrated with log is arranged recently, promptly log saw is removed four flaw-pieces, form the square material of a band medulla,, operation such as tiltedly cut open and be processed into sheet material then through gummed.But the subject matter of this processing method is: the medulla of trees belongs to juvenile wood, is that timber enlivens part most, and the moisture content of it and sapwood, heartwood differs greatly, and therefore is prone to most seasoning defect drying defect when the drying of wood.In addition, whether square bar medulla part is turned black or peeled off on the surface is difficult to expect, when using the square bar converted products of band medulla, as finding that having defective is difficult to remedy, and cause the product degradation or become waste product, and the wood grain patterns of product is very single.

In view of the foregoing, the objective of the invention is: provide a kind of more simple, effectively the wooden boards processing method, it is suitable for requirements of large-scale production, can improve the quality and the class of product, make product have diversified native texture pattern, more attractive in appearance, durable.

The object of the present invention is achieved like this: utilize the saw lumber saw according to different requirements log to be processed into difform section bar, the cross section of this section bar is square, rectangle, trapezoidal and pentagon, removes the medulla part of log simultaneously.After the section bar drying, plane into desired specification with planer, again section bar is put by certain arrangement sequence, on faying face, be coated with the integrated timber special glue, be pressed into rectangular gluing wood.Utilize the circular sawing machine saw to cut open the diagonal of laminated wood, each gummed wood saw cuts open into two triangle laminated woods, with same integrated timber glue two triangle laminated woods are composed the parallelogram laminated wood, saw along one side of parallelogram laminated wood with the polishing saw and cut the bar shaped plank, saw cuts open thickness and decides (this bar shaped plank can directly be sold as product) on product thickness.Then according to the grain pattern of strip plank, by certain arrangement sequence the strip plank with wide one-tenth certain specification of same integrated timber splicing and big sheet material with multiple different natural wood grain patterns.

The extremely long-pending effect that the present invention has: bonding process is easy, only needs 2-3 time gummed in the whole process.Because section bar has been synthesized big laminated wood, can avoid the process that repeatedly repeats, improve production efficiency, thereby be more suitable for the production in enormous quantities of product.With the product that this kind method processes, have more attractive in appearance, various natural texture pattern, stronger, wear-resisting than common plain-sawed lumber and quarter sawing material crushing resistance, the distortion little.This product can be widely used on construction and decoration and the furniture.

Describe the present invention in detail below in conjunction with accompanying drawing: utilize the saw lumber saw that the log (see figure 1) is processed into difform section bar according to different requirements, the cross section of this section bar is rectangle, square, trapezoidal and pentagon, remove the medulla part of log simultaneously, in order to improve the volume recovery of log, every log also can processed two or more section bar (see figure 2).After the section bar drying, plane into required specification with planer, again section bar is put in sequence, on faying face, be coated with the integrated timber special glue, be pressed into the rectangular gluing wood (see figure 3).Utilize the circular sawing machine saw to cut open the diagonal l1 (see figure 3) of rectangular gluing wood, each gummed wood saw cuts open and cuts open into two triangle laminated woods, with same integrated timber special glue two triangle laminated woods are composed parallelogram laminated wood (see figure 4), cut bar shaped plank (seeing Fig. 5 a, 5b, 5c, 5d, 5e and Fig. 6 a, 6b, 6c, 6d, 6e) along the L2 saw again, saw cuts open thickness to be decided on product.Then according to the grain pattern on the strip plank, by certain arrangement sequence the strip plank with the wide one-tenth certain specification of same integrated timber splicing and the big sheet material with multiple different natural wood grain patterns (seeing Fig. 7,8,9,10,11,12).Whole process overview is asked for an interview accompanying drawing 13.

Claims

1, a kind of manufacture method of wood-based planet, it is characterized in that: utilize the saw lumber saw log to be processed into difform section bar according to different requirements, the cross section of this section bar is square, rectangle, trapezoidal and pentagon, remove the medulla part of log simultaneously, after the section bar drying, plane into desired specification with planer, again section bar is put by certain arrangement sequence, on faying face, be coated with the integrated timber special glue, be pressed into rectangular gluing wood.Utilize the circular sawing machine saw to cut open the diagonal of laminated wood, each laminated wood is sawn into two triangle laminated woods, with same integrated timber glue two triangle laminated woods are composed parallel four limit row laminated woods, saw along one side of parallelogram laminated wood with the polishing saw and cut the bar shaped plank, saw cuts open thickness to be decided on product thickness.

2, the processing method of a kind of wood-based planet according to claim 1, it is characterized in that: after section bar gummed and saw cut open and process the strip plank, according to the grain pattern on the strip plank, by certain arrangement sequence the strip plank with wide one-tenth certain specification of same integrated timber splicing and big sheet material with multiple different natural wood grain patterns.
