Problems solved by technology

This method improves the utilization rate and use value of small-diameter wood, but for wood cores with a diameter of less than 6cm or even less than 3.5cm, it is very difficult to process them with the same method because they are prone to warping, deformation and cracking; and the method The steps are relatively complicated, requiring a single rough regular hexagonal prism to be finger-jointed and tenon-jointed, milled into a refined regular hexagonal prism, and then assembled to form a glued wood square, which is time-consuming and labor-intensive, which wastes a lot of raw materials, and the utilization rate of raw materials needs to be improved.

Abstract

The invention provides a wood core lengthening process. The wood core lengthening process comprises the following steps that material manufacturing is performed, wherein wood core materials are selected, and then are cut to be made into first hexagonal prism wood cores, quadrangular surrounding edge wood cores and pentagonal prism surrounding edge wood cores, and a part of the first hexagonal prism wood cores each are sectioned into two sections with different lengths in the normal direction of the length direction; gluing is performed; shaping and curing are performed; and mold stripping andmaintenance are performed. According to the wood core lengthening process, a staggered stacking method is adopted, the binding force among the wood cores is improved, assembling and lengthening are combined into one, and comb tenoning is not needed; the wood cores with the relatively large bending degrees in the length direction can also be directly used for lengthening without correction or cutting off; and the problem that the small-diameter wood cores are difficult to utilize is solved, the production process is simplified, and the obtained laminated wood is high in strength and good in quality.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a wood core extension process. Background technique [0002] The main raw material for the production of wood-core glulam is the residue from the production of eucalyptus veneer—the wood core after peeling the veneer. Eucalyptus is the main plantation tree species in southern my country, especially in Guangdong and Guangxi provinces, with an annual mining volume of about 50 million cubic meters. Eucalyptus is currently mainly used for peeling veneer, which is used as raw material for the production of plywood and thin wood. Each cubic meter of eucalyptus will produce about 0.07-0.1 cubic meters of core residue after rotary cutting, and the number of eucalyptus cores is about 4 million cubic meters per year. The raw materials mainly come from Shaoguan, Heyuan, Heping and Pingping areas at the junction of the west and north of Guangdong and Jiangxi, as well as Jiangxi and...
