Description
Technical field
The utility model relates to the device used when a kind of wooden skin is produced, and particularly relates to a kind of device carrying out surface preparation before polishing to wooden skin.
Background technology
Wood skin, (is commonly called as: wooden skin, veneer; English: veneer; Below be referred to as veneer) and faced deorative industry be started in the fifties in last century, through semicentennial development, possessed suitable scale.Particularly recent two decades comes, and along with the great-jump-forward of China's furniture manufacturing industry and decorations industry increases, its development is advanced by leaps and bounds especially, has emerged in large numbers a large amount of industry experts.
Usually, what process natural veneer is the method adopting slicing.Its process flow is as follows: the log → block → side of cuing open → softening (decatize or poach) → slicing → oven dry (or not drying) → shearing → test package → warehouse-in is following only introduces wherein three important steps:
Cut and cut open
After log enters factory, first according to Len req cutting into lengths, when then cuing open flitch processed again, saw to must be selected to cut open scheme according to log diameter, the grain of wood and the flitch fixing means on slicer, make the veneer width of slicing be not less than relevant requirements.
Rationally not only volume recovery is high for scheme, and obtained quarter sawing veneer is many, and flat-cut veneer is few, and products obtained therefrom decorative value is high.The log of Different Diameter level will adopt different saws to cut open scheme.Heavy line in figure is saw hatching line, and the direction of arrow is the slicing direction of planing tool:
In actual production, the log that diameter is less than 400mm adopts saw to cut open option b usually, and diameter is that the log of 400 ~ 800mm then adopts saw to cut open D and E more.When adopting these saws to cut open scheme production veneer, plate production rate is high, and veneer quality is better, and slicer efficiency is higher.
Boiling
Flitch is after boiling (i.e. hydrothermal treatment consists), and the plasticity of timber increases.The most effectual way improving timber plasticity is that temperature and these two factors of moisture content are coordinated adjustment simultaneously, and the temperature not only improving timber simultaneously but also increase the moisture content of timber.In actual production that Here it is, usual saturated vapor or hot water carry out the reason place of boiling process one hydrothermal treatment consists to flitch.
First, when flitch puts into boiling pond, should by seeds, flitch specification is carried out respectively; Preferably the temperature remains within the normal range for water temperature, and slowly heat up, in order to avoid cause flitch to ftracture because of thermal stress.When rising to more than 40 DEG C, more programming rate should be slowed down; Overcook also can reduce veneer quality; Water through usually Scavenger resin, bark, silt, and often should be changed in boiling pond, pollutes to reduce flitch; Flitch after boiling process should put into the wood of the storage before slicer warm water tank in time, is incubated 40 ~ 50 DEG C of scopes (fixed with seeds and veneer thickness).Following table lists the boiling benchmark of several timber, only for reference.
Dry
After dry, moisture content General Requirements is advisable 8% ~ 12%, and veneer drying equipment has the hothouse of cylindrical drier and band drier and the batch operation of working continuously.Hothouse is old-fashioned drying equipment, very uneconomical, but dry mass is better.Most widely used is cylindrical drier.Relatively the veneer, particularly thickness of book are less than the veneer of 0.4mm, must adopt band drier.
Veneer needing to carry out japanning process to veneer, in order to obtain good japanning effect, needing to carry out grinding process to veneer before japanning after manufacturing, and increases the adhesive force of paint in veneer surface, to obtain good japanning effect.But in the production process of reality, we find when carrying out grinding process to wooden skin, grinding wheel when processing because the existence of thin sheet surface impurity accelerates the wearing and tearing of grinding wheel, and cause veneer surface impaired in polishing, paint in the coating of this place uneven, thin plate after coating just face is concavo-convex uneven, affects the surface quality of thin plate; Need the template of japanning, the flatness on surface may not reach requirement sometimes, and after japanning, thin sheet surface also can be concavo-convex uneven, and japanning effect is poor.
Utility model content
In order to overcome existing to wooden skin carry out grinding process be exist defect, the utility model provides a kind of wooden skin pretreatment unit, grinding process is carried out again after pretreatment being carried out to wooden skin with this device, after this device pretreatment, when polishing, the wearing and tearing of grinding wheel are reduced greatly, and substantially increases the surface smoothness of wooden skin, obtain good japanning effect.
