Embodiment Construction

[0035] Attached below figure 1 To attach Figure 13 , to further describe the specific embodiments of the present invention.

[0036] Using small-diameter wood with a diameter of 60mm to 110mm to prepare a large-format sheet with a thickness of 5mm to 20mm includes the following steps:

[0037] Step 1: wood section preparation: first cut the small-diameter wood with a diameter of 60mm to 110mm into a length specification of 1000mm, and then cut the wood section according to the small head diameter of 60mm to 69mm, 70mm to 79mm, 80mm to 89mm, and 90mm to 99mm , The size grade of 100mm~110mm is divided into five diameter specifications, and then the wood section is dried to a moisture content of 12%.

[0038] Step 2: Processing rough regular hexagonal prism: as attached figure 1 As shown, the wood sections of the five kinds of diameters are respectively cut into rough regular hexagonal prisms by using a CNC indexing double-saw circular saw machine with automatic centering fun...

Abstract

The invention discloses a method for preparing a large-size sheet by using small-diameter wood. The method comprises the steps of: cutting small-diameter wood with a diameter of 6-11cm into wood sections with lengths of 1m, grouping into 5 groups according to the diameter of the small head and the 10mm difference, and drying until the water content is 12 percent; sawing the wood sections into rough regular hexagonal prisms, inscribed circles of bottom surfaces of which are 46mm, 56mm, 66mm, 76mm and 86mm, extending through a finger joint tenon and cutting according to the specification, milling into refine regular hexagonal prisms, inscribed circles of bottom surfaces of which are 40mm, 50mm, 60mm, 70mm and 80mm; symmetrically splitting the regular hexagonal prisms into quadraprisms through the maximum diagonal plane; symmetrically splitting the regular hexagonal prisms into pentagonal prisms through a plane vertical to the side surfaces of the hexagonal prisms; and selecting the quantities of the refine regular hexagonal prisms, and the pentagonal prisms and the quadraprisms, thereby obtaining a rectangular large-section glued wood beam through coating, assembling and bidirectional-pressurizing, and sawing into the large-size sheet with the thickness of 5-20mm. According to the method, the utilization rate and the use value of the small-diameter wood are improved.

Description

technical field [0001] The invention belongs to the field of wood processing, relates to the utilization technology of small-diameter wood, and is embodied as a method for preparing large-format veneer by using small-diameter wood. technical background [0002] Due to the implementation of natural forest protection projects in our country, the felling of natural forests has been reduced, and the planting area of ​​artificial forests has increased. For example, in southern China, masson pine and Chinese fir are the main plantation tree species, and their forest land areas are 1203.50 million hm 2 and 11.2687 million hm 2 , the proportion of area accounted for 7.74% and 7.24% of the country respectively, ranking second and third respectively; while the storage volume reached 587,877,200 m 3 and 734.0948 million m 3 , accounting for 4.40% and 5.49% of the national total respectively. The phenomenon that large-diameter timber gradually decreases while the number of small-dia...
