Abstract
The invention relates to a technology for making small-diameter logs into laminated wood, which comprises the following steps: sorting the logs with standard diameter, cutting off the long small-diameter logs with fixed length and extending the short small-diameter logs with fixed length to obtain log sections with standard length; cutting the log sections with standard length into small-sized regular hexagonal prisms or semi-regular hexagonal prisms; coating cold pressing adhesives on a plurality of surfaces of the prisms; and carrying out assembling in a certain mode, cold-pressing under high frequency and aging to obtain the laminated wood. The technology of the invention can effectively improve the utilization ratio of the small-diameter logs, enhance the strength and the dimensional stability of the laminated wood made of the small-diameter logs, enlarge the application field of the laminated wood made of the small-diameter logs, increase the added value of the small-diameter logs and improve the production efficiency of the laminated wood.
Description
(1) technical field
The present invention relates to a kind of small diameter grade log and prepare the integrated timber technology, belong to composite wooden material manufacturing technology field.
(2) background technology
Along with the minimizing day by day of natural big footpath level high-quality timber, the short period artificial forest account for timber resources proportion in continuous increase, will become one of China's primary timber resource from the small diameter grade log of artificial forest, as southern small dimension woods such as metasequoia, eucalyptus, masson pines.Country's standard of wood regulation, the small diameter grade mill scale directly is 6-16cm, length class is 2-6m.And small diameter grade log processing and utilization is unreasonable at present, and sawn timber volume recovery and utilization rate are low.
It mainly is by different sawing procedures that existing small diameter grade log utilizes method, improves the volume recovery of small diameter grade log.The sawing procedure of small diameter grade log has treating selvedge sawing procedure, unedged lumber sawing procedure, tangerine lobe shape sawing procedure and trapezoidal sawing procedure.No matter select which kind of down saw method, its purpose all is in order to improve the volume recovery of sheet material, yet the preparation stock board will be selected sawing processing for use, and this just unavoidably can cause the loss of swage set, i.e. small diameter grade log waste is serious.In addition, stock board is made integrated timber through gummed, can cause a large amount of adhesive wastes, and complex process, production efficiency is low.
(3) summary of the invention
Behind long material fixed-length cut-off of small diameter grade log (metasequoia, eucalyptus, masson pine) and short material fixed length spreading, the veneer bolt of preparation specification length, by the saw lumber combination machine of chipping, the veneer bolt of specification length, be processed into positive hexagonal prism of small dimension or half positive hexagonal prism, apply cold pressing glue and half three of positive hexagonal prisms apply cold pressing glue in the positive hexagonal prism multiaspect of small dimension, carry out assembly in a certain way, then by the high frequency splicing of colding pressing.The present invention, with the microcephaly of small diameter grade log locate cross circular section in to connect regular hexagon be editing objective, the small diameter grade veneer bolt of certain diameter is processed into the positive hexagonal prism of small dimension.
As improvement, small diameter grade log fixed length is of a size of 2-2.5m, and it is exactly an integrated timber specification length dimension, helps the subsequent set processing and utilization of becoming a useful person, and carries out thick veneer slicing processing as integrated timber.
As improvement, for advancing level, it helps efficiently to improve small diameter grade log utilization rate to the small diameter grade log diameter with 1cm.
As improvement,, the specification length veneer bolt of different-diameter level can be processed into positive hexagonal prism of different small dimensions and half positive hexagonal prism by having the adaptive saw lumber combination machine of chipping.It helps to process the small diameter grade log of different-diameter specification, improves the utilization rate of small diameter grade log.
As improvement, apply the positive hexagonal prism of small dimension or the half positive hexagonal prism of cold pressing glue, with multi-form method assembly, can form positive hexagonal prism of big specification or class four prisms cylinder.It helps the integrated timber processing and utilization, improves working (machining) efficiency.
As improvement, the cold pressing glue that applies on the positive hexagonal prism of small dimension is milky white adhesive or EPI glue, and it effectively improves the intensity and the dimensional stability of small diameter grade log integrated timber.
Beneficial effect of the present invention: this small diameter grade log prepares the integrated timber technology, the characteristics of small diameter grade log length and footpath level have been fully taken into account, with small diameter grade log fixed length, adopt the regular hexagon saw lumber scheme of chipping, it is processed into the positive hexagonal prism of small dimension, and processes the usefulness that smear metal can be used as wood shavings, made full use of the small diameter grade log resource, and adopt the high frequency mode of colding pressing, can reduce energy resource consumption and enhance productivity.
Adopt this small diameter grade log to prepare the integrated timber technology, utilize efficiently that small diameter grade log resource, assemble pattern are simple, the cycle of colding pressing is short, production efficiency is high, integrated timber dimensional stability height, low, the no free formaldehyde release of energy resource consumption and added value of product advantages of higher.Therefore, the present invention has boundless production application prospect.

(5) specific embodiment
The invention will be further described below by embodiment.
1 fixed length: with the vertical fixed-length cut-off of small diameter grade log or vertical fixed length spreading of different length, the long small diameter grade veneer bolt of preparation 2m, the specification veneer bolt of the level of sorting Different Diameter then, as shown in Figure 2.
2 square stocks processing: by having the adaptive saw lumber combination machine of chipping, the specification length veneer bolt of different-diameter level is processed into positive hexagonal prism of different small dimensions (1) and half positive hexagonal prism (2), as shown in Figure 3 and Figure 4.
3 gluings:,, be depicted as glue-line as (3) among Fig. 1 with the positive hexagonal prism of small dimension (1) or half positive hexagonal prism (2) multiaspect or three coating EPI cold pressing glues by automatic glue spreading device.
4 assemblies: as required,, carry out the positive hexagonal prism of big specification (4) assembly, as shown in Figure 5 with positive hexagonal prism of identical small dimension (1) or half positive hexagonal prism (2); Also can carry out class four prisms cylinder (5) assembly, as shown in Figure 6.
5 high frequencies are colded pressing: positive hexagonal prism of big specification (4) that assembly is good or class four prisms cylinder (5) carry out high frequency and cold pressing.
6 display: will cold pressing good positive hexagonal prism of big specification (4) or class four prisms cylinder (5) square stock, carry out displaying in 24 hours, to discharge internal stress, as shown in Figure 1.
