Problems solved by technology

[0003] The technical problem to be solved by the present invention is: use small-diameter wood, processing residues, branch tips, etc. as raw materials to split into small wooden strips and mold them into integrated columns, and then use integrated columns to produce veneers, so as to overcome the traditional method of using large-diameter The practical difficulty of the lack of raw materials for making veneers with grades

Embodiment Construction

[0015] The present invention is just illustrated with implementation below: use the small-diameter timber of the same tree species, the branches of the tree, and the remaining materials from processing, splitting, cutting into thicknesses of about 0.5mm and width of about 10mm, and applying when the moisture content is 12%. Glue for cold pressing, small wood strips weighed in a reasonable amount are arranged longitudinally in parallel and evenly in the mold, so that the inner cavity of the mold is filled and then molded, and a press with a unit pressure of 2.5Mpa is selected for cold pressing to form an integrated column. It can be cut into veneers in a steam rotary cutter.

[0016] The present invention adopts the small-diameter wood of the same tree species, branches or small wood strips made from processing residues as raw materials, and then makes integrated columns and then rotary-cuts veneers, which can effectively use small materials and waste materials to make large mat...

Abstract

The invention discloses a veneer making method of small integrated wood strip column, which comprises the following steps: cutting the manufacturing remains into small wood strip; drying the small wool strip with 12-15 percent moisture rate to apply glue or apply glue directly; calculating the quantity of small wool strip according to the bulk and weight of integrating column; arranging the small wool strip along longitude paralleling on the mould with semi-circle pipe upper-mold and lower-mold to assemble the model; moulding; selecting 1.0-2.5MPa compressor to do cold compression; solidifying and placing to make the small integrated wood strip column; doing rotary shaving through common rotary shaver when moisture ratio is more than 25 percent; doing rotary shaving through steam rotary shaver when moisture ratio is less than 20 percent; doing rotary shaving through flat sprayer; making the veneer. The invention utilizes waste material to make large board (veneer), which expands the source of veneer.

Description

technical field [0001] The invention relates to a method for rotary-cutting veneers after making integrated columns with small wooden strips. Background technique [0002] The traditional veneer production is to choose logs with large diameter, straight and few defects as raw materials. This kind of wood is expensive and low in quantity, and the global forest protection makes this material scarce. CN92101383.3 discloses Zhang Wanli's "technical method for rotary-cutting veneer" scheme, which also uses large-diameter timber for rotary-cutting. Contents of the invention [0003] The technical problem to be solved by the present invention is: use small-diameter wood, processing residues, branch tips, etc. as raw materials to split into small wooden strips and mold them into integrated columns, and then use integrated columns to produce veneers, so as to overcome the traditional method of using large-diameter There is a real difficulty in the lack of raw materials for making ...
