Background technology
In order to prolonging wood using life, slow down Forest resources dynamics, preserve the ecological environment; modification is carried out to wood surface; overcome during woodwork uses the shortcoming such as not durable, yielding existed, increase convex-concave vision and the tactile feel of superficial makings, be the hot technology of wood processing field always.Not long ago occur the treating method of wood surface carbonization, in anticorrosion, mothproof, the waterproof of increase wood surface etc., obtain obvious effect.
Superficial charring wood is generally with oxygen welding gun barbecue, makes wood surface have the very thin charring layer of one deck, can the paint of analogy timber to the change of wood performance, but can highlight the wood grain of concave-convex surface, produces stereoeffect.Because its nutritional labeling is destroyed, make it have good antiseptic insect-repelling function, because its hemicellulose water absorbing functional groups is reorganized, product is made to have good physical property, charing antisepsis wood is real Green Product, although product has antiseptic insect-repelling performance, not containing any harmful substance, not only increase the service life of timber, and the waste disposal in production and use procedure and after using can not have any negative effect to human body, animal and environment.
Although surface carbonation woodworking has been applied in production, but also have a lot of shortcoming as oxygen welding gun flame in carbonization internal flame, flame envelope burning time oxygen content different, the temperature of internal flame, flame envelope and Carbonization Conditions are different, after will causing carbonization, wood surface carbonizing degree is uneven, excessively carbonization sometimes, the unstable product quality produced; In carbonisation, need people's manual operation oxygen welding gun, visually see the effect of carbonization, energy consumption is large, and production cost is high, work is severe, efficiency is low.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of carbonizing plant and method of wood surface, thermal source is done by large powerful laser, the light source moment sharply heat wood surface of stripe shape is produced by optical transform, play the effect of flash carbonization wood surface, adjusted the degree of wood surface carbonization by adjustment LASER Light Source and the translational speed being carbonized timber, overcome existing wood surface carbonization treatment surface quality uneven; Energy consumption is large, the problems such as work situation is poor, efficiency is low.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of carbonizing plant of wood surface, it is characterized in that, comprise laser generator, recessed cylindrical mirror, convex cylindrical mirror, total reflection prism and timber conveyer belt, Laser emission path is formed between laser generator and recessed cylindrical mirror, laser first reflection path is formed between recessed cylindrical mirror and convex cylindrical mirror, and form the second reflection path between convex cylindrical mirror and total reflection prism, then form laser exposure pathways between total reflection prism and timber conveyer belt.
Further, described laser generator is corresponding with the translational speed of timber conveyer belt to be arranged, and corresponding relation is: (40-80) W:1m/min.
A kind of carbonization method utilizing above-mentioned carbonizing plant to carry out wood surface, it is characterized in that, comprise the following steps: will treat that the timber of carbonization is put on a moving belt, open laser generator, produce a branch of parallel laser beam, described laser beam is transmitted on recessed cylindrical mirror, recessed cylindrical mirror carries out bunching back reflection on convex cylindrical mirror to launching the laser beam come, form the ellipse light spot being similar to rectangle, ellipse light spot reflexes on total reflection prism by described convex cylindrical mirror again, and ellipse light spot is irradiated to the wood surface treating carbonization by total reflection prism, described conveyer belt drives timber to move with fixing speed, carbonization treatment is carried out to wood surface entirety, timber after carbonization treatment is through cooling, carbonization finished product is obtained after removing carbon dust process.
Further, in the process of carbonization, also comprise to treating that the step that nitrogen carries out flameproof protection is sprayed on carbonized wood surface.
Usefulness of the present invention is: compared with Wood carbonization device and method of the present invention roasts mode with traditional oxygen welding gun, laser surface carbonization have easily realize serialization, carbonization uniform quality, to need the accurate carbonization in the position of carbonization, can automated production, production efficiency high, easily realize the advantage of mass production, can spray nitrogen prevents material surface over oxidation simultaneously, increases the security of processing method.
