Embodiment 1

[0027] refer to figure 1 and figure 2 , a kind of manufacture method of composite bamboo floor, comprises the following steps: 1. cut off the protruding part of the branch on the bamboo tip; ; 3. rolling the bamboo chips with a bamboo rolling machine to obtain the rolled bamboo chips; 4. processing the rolled bamboo chips with a fixed width and thickness;

[0028] Then, the 2-4 layers of rolled bamboo slices are glued and assembled along the grain, and then hot-pressed into a bamboo core board, and the sides of the large-diameter bamboo strips are glued and assembled, and then hot-pressed into a bamboo veneer, and then press the surface Bamboo veneer, core layer bamboo chip core board, back layer wood veneer or bamboo veneer are glued and assembled, and the slab is sent to the press for secondary hot pressing to obtain a four-layer slab; The billets are then processed into bamboo flooring through trimming, tenoning, sanding, finishing, drying and other processes.

[0029] ...

Embodiment 2

[0039] In this example, the sides of the large-diameter bamboo strips are coated with glue to assemble the blanks, and then hot-pressed into bamboo strip veneers, and then the surface layer bamboo strip veneer, the core layer rolled bamboo slices, the back layer wood veneer or bamboo veneer Apply glue to assemble the slabs, and send the slabs into the press for secondary hot pressing to form slabs.

[0040] Other steps in this embodiment are the same as in Embodiment 1.

Embodiment 3

[0042] refer to figure 1 and figure 2 , the steps of the present embodiment 1.-4., 8. are the same as embodiment 1. Other steps of this embodiment are:

[0043] ⑤ Apply glue to the finished rolled bamboo chips, large-diameter bamboo strips and wood veneers or bamboo veneers, and the amount of glue applied is controlled at 160-200g / m 2 .

[0044] ⑥According to the surface bamboo strips, core bamboo slices, back wood veneer or bamboo veneer, the blanks are assembled along the grain, and then tied with nylon ropes. When the core layer bamboo chips are assembled, the green side and the yellow side should be arranged alternately in sequence.

[0045] ⑦ Send the assembled slabs into the press for hot pressing, the positive pressure is 2.0-3.0MPa, the side pressure is 2.5-3.5MPa, the hot-pressing time is 0.5-0.8min / mm, and the hot-pressing temperature is 90-110°C.

Abstract

A manufacturing method of a composite bamboo flooring comprises the following steps: (1) cutting branch extruding parts on a bamboo branch tip; (2) splitting a small-diameter bamboo or the bamboo branch tip into 2-4 pieces of bamboo chips according to the size of the diameter by a bamboo splitting machine; (3) rolling the bamboo strips by a bamboo roller to obtain rolled bamboo strips; and (4) processing the rolled bamboo strips with a specific width and a specific thickness; then, taking the rolled bamboo strips as a core layer, bamboo splints of a large-diameter bamboo as a surface layer and a wood veneer or a bamboo veneer as a back layer, and obtaining a board blank after glue spreading, assembling and hot pressing; and the board blank is made into the bamboo flooring by procedures of trimming, opening chase mortise, sanding, finishing, drying and the like. The method can help improve the utilization rate of the bamboo, lower the production cost and realize the high-efficiency utilization of the small-diameter bamboo and the processing remainder of the bamboo, that is, the bamboo branch tip.

Description

technical field [0001] The invention relates to a manufacturing method of a composite bamboo floor. Background technique [0002] In recent years, my country's bamboo flooring industry has developed rapidly, and has become the world's largest exporter of bamboo flooring. But the bamboo floor of industrial production is to be raw material substantially with the large-diameter moso bamboo more than 8 cun of eyebrow circumference at present, through splitting, planing, three-proof treatment and gluing group blank hot-pressing gluing to form. The bamboo floor produced by this method can only use large-diameter bamboo as raw material, which has high requirements for bamboo raw materials, and has low utilization rate of bamboo (only about 20%), large billeting workload, large glue consumption, and high production cost. high question. And a large amount of medium and small diameter bamboos and bamboo wood processing residues-bamboo tips are not fully utilized, resulting in waste ...
