And arched and pointed flute accounts for about 15-25% of the bamboo chips, that is to say, the real utilization rate of the original bamboo is only about 18-20%, and more than 80% of the remaining all become waste materials, causing a great waste of resources.

Embodiment Construction
[0020] Embodiment: As shown in each schematic diagram, arc-shaped substrate bamboo plywood gluing process and device are that the bamboo chip after the original bamboo punching is dried, carbonized, and the cross-section after cleaning the surface is an arc-shaped substrate. The upper and lower two special planers with concave and convex arcs respectively plan the front and back sides of the substrate, and then glue and extrude it. The body production process must go through:
[0021] Raw sheet processing - sawing the raw bamboo into several bamboo tubes according to the width of the bamboo plywood, punching the bamboo tubes into straight wool substrates according to the thickness of the bamboo plywood, and then drying, carbonizing and cleaning the substrate;
[0022] Curved surface planing—select a planer with a suitable blade radian according to the curved surface shape of the curved substrate 7, and under the push of the upper conveying roller 1 and the lower conveying rolle...

The invention discloses a bonding process and a bonding device for bamboo plywood with arc base pieces. Bonding is performed by virtue of the natural shapes of the bamboo base pieces, which is a thorough innovation for the existing pressing process for bamboo plywood. Before pressing, the base pieces need to be pre-treated, and a planing tool with a proper edge radian is chosen according to the arc-surface shapes of different bamboos. The planing tool with an inwards-recessed arc edge and an outwards-projected arc edge is used for properly planing the front surfaces and the back surfaces of the base pieces, and then the outwards-projected arc surfaces and the inwards-recessed arc surfaces of the glued arc base pieces are closely fitted and then placed in an extrusion die to be formed in sequence. According to the invention, because an arch on the back surface of each arc base piece and two sharp ledges in the arc base piece have no need to be planed away, a considerable amount of bamboo resources can be saved, so that an immeasurable contribution building for a resource-saving society is provided. For manufacturing enterprises, cost can be saved and economic benefits can be improved. Moreover, because the base pieces are fitted with each other in the shape of an arc, and the binding force among the base pieces is improved, so that the impact strength and the tear strength of the bamboo plywood in a plane vertical direction are further improved.
Description
technical field [0001] The invention relates to the production technology of bamboo plywood, in particular to a gluing process and device for arc-shaped substrate bamboo plywood using the natural form of bamboo slices as the substrate. Background technique [0002] Bamboo products, bamboo furniture and bamboo handicrafts currently on the market are basically made of high-temperature carbonized, extruded and glued bamboo plywood. This is a great contribution to "substituting bamboo for wood and saving resources" in my country. Because the bamboo all over the Jiangnan area of our country, with its extremely strong reproductive ability, has a growth cycle of 3 to 5 years; it has a significant effect on promoting ecological balance and protecting the ecological environment. It is the first important resource for saving resources, saving energy and reducing emissions, protecting forest resources, preventing soil erosion and natural disasters. In fact, bamboo is indeed more sup...
