Example Embodiment

[0025] The present invention will be further described below in conjunction with embodiments:

[0026] As shown in the drawings, the method of the present invention includes the following steps:

[0027] a. Send small-diameter wood, branch wood, peel-cut wood core or incomplete natural trees (such as medlar, etc.) with a diameter of less than 100 mm and greater than 10 mm into a flat cold press or rolling machine with peeling Flattening and peeling treatment;

[0028] b. Then the squashed and peeled small-diameter wood, branch wood, peel-cut wood core or incomplete natural trees are fed into the wood fiber separator in the length direction to carry out the radial coarse and fine separation of wood fibers;

[0029] c. Expand and smooth the above-mentioned finely separated wood fibers radially;

[0030] d. Dry the above-mentioned smooth wood fiber;

[0031] e. Apply adhesive to the dried smooth fiber;

[0032] f. Use the flat fiber after sizing the adhesive, and start the vertical s...

Abstract

The invention discloses a preparation method for producing a wood board or a flitch beam, which is characterized by comprising the following steps: a, flattening and peeling small wood, brushwood, rotary-cut heart wood or useless natural wood which has a diameter of less than 100 millimeters and more than 10 millimeters; b, radially and roughly separating and finely separating fibers of the wood; c, radially expanding or leveling the finely separated fibers of the wood; d, drying the level fibers of the wood; e, applying a bonding adhesive onto the dried and leveled fibers; f, starting longitudinally splicing and paving the leveled fibers obtained after bonding adhesive application along the direction of the fibers of the wood to form a uniform and level wood fiber board blank; g, forming the wood fiber board blank through hot press to form a rough board; h, cooling the rough board; and I, cutting the rough board to form different boards or flitch beams.

Description

Technical field [0001] The invention relates to a preparation method for the production of wooden planks or squares. The method is particularly suitable for the use of small-diameter wood, branch wood, rotary cut wood core or unfinished natural trees (such as wood) with a diameter of less than 100 mm and greater than 10 mm. Medlar, etc.) to manufacture wooden boards or squares. Background technique [0002] In recent years, under the severe situation of the approaching global ecological crisis, various countries have restricted the logging of natural forests in different ways. With the launch of my country's "natural protection" project, the quality of large-diameter wood needed for people's lives has become less and less expensive. For these reasons. Planted forests have become the main raw material for wood needed by the people in our country. [0003] As my country's plantation forests are still in the initial development period, and the cultivation and protection measures are...
