Abstract

A method for manufacturing a glue laminated bamboo material, comprising: positioning and overlapping part manufacturing, blank assembly, and lamination processes. In the positioning and overlapping part manufacturing process, a positioning and overlapping part is processed at at least one extremity in the lengthwise direction of a finely planed bamboo strip (4). In the blank assembly process, multiple pieces of finely planed bamboo strips (4) are sequentially overlapped along the lengthwise direction to form overlap areas (7), the top sides (5 and 6) of adjacent two bamboo strips (4) are automatically staggered with each other when overlapped, and then, bamboo strip sets extending in the lengthwise direction are sequentially arranged into sets along either the widthwise direction or the height direction, where the overlap areas (7) are staggered with each other. In the lamination process, the blank-assembled bamboo strip sets are extruded along the height direction and the widthwise direction until the top sides (5 and 6) of two bamboo strips (4) are flush. The method has a simple overlapping process and high overlapping efficiency, prevents the problem of an overlap gap from occurring in the lamination process, and increases work efficiency and product pass rate in the manufacturing of the glue laminated bamboo material.

Description

Method for manufacturing bamboo laminated material

The invention belongs to the technical field of bamboo laminated timber manufacturing in the wood-based panel industry, and relates to a method for manufacturing bamboo laminated timber.

technical background

Bamboo is a world-recognized low-carbon, environmentally friendly, ecologically and green material that is sustainable (3-6 years old) and is a renewable natural resource. Bamboo can regulate indoor humidity, anti-static, and is good for human health. Especially after the deep carbonization of the sheet, the processed bamboo furniture will not change color for a long time, and it can enhance the adsorption of harmful gases in the room. After the bamboo is completely sterilized by high-temperature cooking, it can fundamentally prevent insects and enzymes. Bamboo has natural color, elasticity, moisture resistance and high hardness. Bamboo grows only one-tenth of the time of wood. It has sustainable regrowth characteristics after cutting, and is more in line with the low-carbon concept in modern economy. Bamboo is harder than wood. Compact, high pressure and flexural strength; clear bamboo grain, beautiful surface, natural color, pleasant bamboo, elegant texture; bamboo does not accumulate dust, does not condense, easy to clean, avoids the breeding of cockroach bacteria, It eliminates the disturbance of insects; Bamboo can automatically adjust the humidity and moisture resistance, low thermal conductivity, and has the characteristics of warm winter and cool summer. Bamboo has the function of absorbing ultraviolet rays, which makes people feel comfortable when living indoors, and can prevent myopia. The occurrence and development of eye diseases; bamboo sound absorption sound insulation, in addition to bass, residual pressure, effectively eliminate noise; bamboo shrinkage is small, with a high degree of splitting, elasticity and toughness.

Bamboo has been widely used as a raw material for wood-based panels, construction, furniture, paper, medicine, food, and chemical industries because of its many advantages. It is an effective substitute for wood.

Bamboo laminated timber includes indoor and outdoor bamboo panels, indoor and outdoor bamboo profiles, indoor and outdoor bamboo furniture panels, indoors Exterior moldings, indoor and outdoor panels, etc. As a new type of substrate, bamboo laminated timber maintains the physical and mechanical properties of bamboo. It has the characteristics of large size, small deformation, stable size, high strength, good rigidity and wear resistance. It can be sawed and shaved. , boring, boring, drilling, sanding, assembly and surface finishing. Since the bamboo laminated timber is produced by high temperature cooking, the finished product has good sealing property, and can effectively prevent insects and mildew. Compared with wooden furniture, bamboo has strong physical and mechanical properties. Therefore, under the same bearing mechanical strength, bamboo laminated timber components can meet the strength requirements in a small size, and the overall shape is lighter and more reflective of bamboo. Rigidity and the aesthetics of force. With the improvement of people's living standards, the demand for bamboo laminated timber is increasing.

In the manufacturing method of the traditional bamboo laminated timber, in order to achieve the purpose of seamless lengthening, a method of opening various buckle-type mutual snaps at the end of the fine-grained bamboo strip is generally adopted, and the disadvantage of this method is: The shape of the buckle at the end is complicated, the processing technology is complicated, the processing is difficult, the technical requirements for the worker are high, and one knife can only process one buckle type, and the buckle gap becomes larger when the cutter is blunt; High tool requirements, large tool loss, difficult product quality control, and low product qualification. At the same time, the method has a large processing margin and low utilization rate of bamboo.

In the preforming process of the present invention, the adjacent two overlapping regions may be offset from each other by less than any length of the fine bamboo strip. As a preferred embodiment of the present invention, the overlapping regions are staggered by 5-30 cm.

As a preferred embodiment of the present invention, the pressing force in the press-bonding step is 50 N/cm ^{2 to} 1500 N/cm ² . The invention has the beneficial effects that: since the positioning lap joint is provided at the end of the fine bamboo strip, the lap joint of the fine planing bamboo strip can be automatically and closely fitted, and the lap process is simple, and the worker operates It is more convenient and has high lap joint efficiency. Moreover, due to the positioning effect of the positioning surface, the misalignment distance of each lap joint is uniform, thereby avoiding the problem of lap seams occurring in the splicing process, which greatly improves the problem. The work efficiency and product qualification rate of bamboo laminated timber production reduce the production cost. No need to use tools for machining positioning surface and overlapping inclined surface, only ordinary saw can be completed, and no special processing equipment is needed, just ordinary saw One can be completed, one worker can be completed independently, and the technical requirements for workers are low. Since the lap joint manufacturing process only needs to cut out the lapped slope and the locating surface, the bamboo material is small in amount and the bamboo material utilization rate is high, and the strength of the bamboo tiling material is also high due to the misalignment of the affixing portions. Get guaranteed and improved. This manufacturing method can use fine-grained bamboo pieces of any length, making full use of bamboo resources.
