Manufacturing method of whole-piece bamboo-bunch veneer and overlong bamboo-bunch laminated veneer lumber

Abstract

The invention discloses a manufacturing method of a whole-piece bamboo-bunch veneer and an overlong bamboo-bunch laminated veneer lumber. The method comprises the specific steps that a raw material is selected and pretreated; bamboo wood is conveyed to brooming rolling equipment in a rift grain direction; the conveyed bamboo wood is broomed, beaten and rolled by the equipment, and is subjected to devillicate treatment after a plurality of periods to be manufactured into bunchiness fibers with uniform specifications; bunchiness fiber units that are arranged tightly and orderly in the rift grain direction are discharged; the bunchiness fiber units are sewn or bonded to ensure that the bunchiness fiber units in the same row are connected together; a bamboo-bunch veneer is manufactured; the whole-piece bamboo-bunch veneer is manufactured; a plurality of whole-piece bamboo-bunch veneers are overlaid, assembled, and subjected to cold pressing and heat pressing treatment; and the finished overlong bamboo-bunch laminated veneer lumber is manufactured. The whole-piece bamboo-bunch veneer and the overlong bamboo-bunch laminated veneer lumber manufactured by the method are uniform in density; the raw material can be saved greatly on the premise that national standards are met; bamboo green and tabasheer in the raw bamboo wood can be kept; and bamboo wood consumption and waste of manpower and material resources caused by removing the bamboo green and the tabasheer in the prior art can be avoided.

Description

technical field [0001] The invention belongs to the field of bamboo wood-based panel manufacturing, and in particular provides a method for manufacturing integrated bamboo bundle veneer and super-long bamboo bundle veneer laminated lumber. Background technique [0002] my country is rich in bamboo resources, and the area of ​​bamboo forests has reached 5.381 million hectares. Bamboo has the characteristics of easy planting, fast growth, short cycle, and sustainable use of one-time afforestation. It is widely used in the production of wood-based panels. Bamboo wood-based panels are divided into five categories: bamboo plywood, bamboo laminated lumber, bamboo particle board, recombined bamboo and bamboo-wood composite panels according to the types of raw materials that make up the board, the geometric shape of the constituent units and the structure of the board. An important means of manufacturing wood-based panels. At present, the main constituent units of bamboo-based panel...

Problems solved by technology

[0003] At present, most of the hot-pressing equipment in my country's wood-based panel processing enterprises has a maximum format of 2.44m×1.22m. Therefore, cold-pressing technology must be used to process recombined wood with a length greater than 2.44m, which not only occupies a large production site and labor force, but also has low efficiency.
