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.

Embodiment Construction

[0041] The specific steps for making the whole veneer of chemical bamboo bundles in the present invention are: 1) selection and pretreatment of raw materials; 2) preparation of bundle fiber units; 3) production of the veneer of bamboo bundles; 4) completion of the production of the whole veneer of chemical bamboo bundles.

[0042] The specific steps of the method for manufacturing the super-long bamboo bundle veneer lumber of the present invention are: 1) stacking a group of whole bamboo bundle veneers to form blanks; 2) cold pressing; 3) hot pressing. Or: 1) A number of whole bamboo bundle veneers are superimposed and continuously superimposed to form a unit billet, and then a group of unit billets are continuously assembled; 2) cold pressing; 3) hot pressing. The ultra-long bamboo bundle laminated veneer lumber obtained after hot pressing can be further cut to the preset required length

[0043] The selection and pretreatment of the raw material: select bamboo with a length ...

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...
