[0001] The invention relates to the technical field of bamboo board assembly, in particular to a novel reorganized structure bamboo board assembly method. Background Art

[0002] Bamboo is a fast-growing grass plant with strong adaptability. It is widely distributed in southern my country, and many household items are made of bamboo, which can greatly reduce production costs. The pressed bamboo board can ensure the hardness well, and the bamboo board can be pressed and made by multiple methods during the production process. At the same time, bamboo of the same specifications needs to be selected as raw materials; The patent with the patent authorization announcement number CN114523530B discloses a three-layer pressing device and method for producing bamboo boards. The square frame, rotating column, reciprocating screw and grinding head in the grinding assembly are used to drive the two grinding heads to move back and forth alternately to grind the surfaces of the bamboo veneer and the sandwich layer to be bonded, and the protrusions and burrs on the surfaces of the bamboo veneer and the sandwich layer are ground and eliminated. Then, the grinding debris is pushed away and adhered by using the cooperation of the V-shaped cleaning brush plate, the H-shaped plate rack, the installation cylinder with the sticky roller, the winding cylinder and the extrusion cylinder, so that the bamboo chips on the bamboo veneer and the sandwich layer can be thoroughly removed, which is convenient for the subsequent gluing process, so that the bamboo veneer and the sandwich layer can be closely attached together; The patent with the patent authorization announcement number CN115503064B discloses an automatic long-size integrated bamboo board pressing device and method, which realizes the mechanical automation operation of the whole process from the bamboo strip material extension, fixed-length cutting, bamboo strip assembly, transmission, hot pressing board, board discharging, etc. At the same time, in the bamboo strip extension process, continuous extension and continuous cutting can be achieved, so that the interfaces of different bamboo strips in the same bamboo board after the stacking is completed can be staggered and disordered, which is like the staggered and disordered interfaces of woven fibers in the large surface, avoiding the weak points of the interfaces in the same position, and finally achieving the uniform structural strength of the pressed integrated board. The number of extension components, fixed-length sawing components, fixed-thickness stacking components and single-channel hot pressing components can be configured according to the equipment power and other conditions, and they can be accurately transported to the designated single-channel hot pressing component through the transportation component, which is conducive to improving the overall working efficiency of the device and has high adaptability; In the above-mentioned public patent, the method in the patent realizes the pressing of bamboo boards, but there are still the following problems: the deformation degree of the boards increases and the water and temperature resistance test of the boards causes delamination, and the physical properties will be greatly reduced. The reason is that the thickness of the transverse bamboo-based fibers is uneven, and the thickness is the same after pressing with the same pressure, resulting in uneven density, thereby deforming the boards.

[0009] Preferably, in step S4, the bamboo pieces are divided into bottom surface and middle material during combing, and the combing process requirements of each are different. The bottom surface bamboo pieces retain the green and yellow colors of the bamboo, and are crushed and combed to remove the bamboo nodes. The middle material combing needs to remove the green and yellow colors of the bamboo pieces to a ratio of 95% of the total, and the bamboo pieces are combed into a cotton state. The middle material uses middle bamboo pieces and tail bamboo pieces, and the thickness of the two ends of the combed transverse bamboo-based fibers needs to be kept basically consistent.

[0010] Preferably, in step S5, the short-tail bamboo pieces are processed into round bamboo filaments, and the diameter range of the round bamboo filaments needs to be controlled between 0.5 mm and 1.5 mm, and the length of the round bamboo filaments is 900 mm to 1250 mm.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The longitudinal tension of the round bamboo wire is changed to the lateral tension to enhance the lateral tension. During the pressing process, the lateral bamboo-based fibers wrap the round bamboo wire to form a strong wrapping tension, which is similar to the role of steel in building concrete. The advantage of this role is that it is not easy to crack, deform and delaminate. The round bamboo wire acts as a bridge structure to solve the problem of insufficient lateral tension of the reconstructed bamboo board and improve the physical properties of the reconstructed material. At the same time, the method can reduce the production cost of bamboo boards, improve the aesthetics of bamboo board production, and change the specifications of bamboo boards according to specific needs, effectively improving the practicability of the method.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In this embodiment: Figure 1-Figure 2 As shown, in order to solve the problem that the existing method of making bamboo boards will cause board deformation, the specific process of making bamboo boards by this method is disclosed, and the board made by this method can achieve a stable support effect, and its specific contents are as follows: The following steps are involved: S1. Cutting bamboo. During the cutting process, bamboos with an age of more than four years need to be selected; In step S1, the bamboo is cut into three lengths of 2520 mm, 2820 mm and 900 mm to 1250 mm, and the selected bamboo is required to be more than four years old; S2, bamboo fragmentation processing, bamboo fragmentation processing needs to be processed by a fragmentation machine; In step S2, the cut bamboo is subjected to a sheeting process using a sheeting machine, and the sheets are sequentially processed in the order of the root, the middle section, the tail and the short tail; S3, bamboo collision processing, bamboo collision process needs to be installed in different specifications for placement processing; In step S3, the bamboo pieces are arranged in the order of 3 pieces, 4 pieces, 5 pieces and 6 pieces and then subjected to a collision process; S4, combing and disintegrating the bamboo pieces, combing and disintegrating the bamboo pieces into transverse bamboo-based fibers 1; In step S4, the bamboo pieces are divided into bottom and middle materials during combing, and the combing process requirements of each are different. The bottom bamboo pieces retain the green and yellow bamboo, and are crushed and combed to remove the bamboo nodes. The middle material combing needs to remove the green and yellow bamboo pieces to a ratio of 95% of the total, and the bamboo pieces are combed into a cotton state. The middle material uses the middle bamboo pieces and the tail bamboo pieces, and the thickness of the combed transverse bamboo-based fibers 1 at both ends needs to be kept basically consistent; S5, drawing the short tail of bamboo, processing the short tail bamboo pieces into round bamboo wires of fixed specifications 2; In step S5, the short tail bamboo pieces are processed into round bamboo threads 2, and the diameter of the round bamboo threads 2 needs to be controlled between 0.5 mm and 1.5 mm, and the length of the round bamboo threads 2 is 900 mm to 1250 mm; S6, gluing the transverse bamboo-based fibers 1, gluing the transverse bamboo-based fibers 1 and the round bamboo filaments 2; In step S6, the bamboo-based fibers 1 are directional glued, the middle layer is double-sided glued, the round bamboo fibers 2 are soaked, and the round bamboo fibers 2 are glued after the soaking is completed; S7, horizontal bamboo-based fiber 1 laying process; In step S7, the transverse bamboo-based fibers 1 are dried after the gluing treatment, and a new microwave drying method is used to maintain the moisture content at about 15% to 18%; Step S7 includes the following processing steps: drying the transverse bamboo-based fibers 1 and controlling the moisture content therein, and arranging the transverse bamboo-based fibers 1 and the round bamboo fibers 2 in order according to different orientations; (1): The bottom surface is paved with transverse bamboo-based fiber 1. Three pieces need to have their big ends facing outward, the green side facing the bottom, and the yellow side facing up. The last three pieces need to have their big ends facing inward, the green side facing the bottom, and the yellow side facing up. They are laid flat and staggered in order. After the fibers are fully laid, bamboo silk is used to fill the gaps. (2): During the process of laying the round bamboo threads on the bottom surface, the interval between each thread is 10 mm to 50 mm, and the distance is determined according to the diameter of the round bamboo threads. When laying, the two sides should not be over-laid to ensure that the transverse bamboo-based fibers 1 and the round bamboo threads are aligned vertically; (3): During the process of laying the horizontal bamboo-based fiber 1 in the middle layer, the first piece is laid with the big end facing inward, the green side facing up, and the yellow side facing down. The second piece is laid with the big end facing outward, the green side facing down, and the yellow side facing up. The laying is carried out in sequence; (4): During the process of laying the round bamboo wires on the middle layer, the interval between each wire is 10 mm to 50 mm, and the distance is determined according to the diameter of the round bamboo wires. When laying, the two sides of the round bamboo wires should not go over, and ensure that they are aligned up and down; (5): The surface is paved with transverse bamboo-based fibers 1. The big ends of 3 pieces should be facing inward, with the green side facing up and the yellow side facing down. The big ends of the last 3 pieces should be facing outward, with the green side facing up and the yellow side facing down. The fibers should be laid flat and staggered in order. After the fibers are fully laid, bamboo silk should be used to fill the gaps. (6): Check the pavement and fill the gaps inside the pavement, and then press the pavement material into an integrated manner.

[0020] S8, trimming and polishing the bamboo board after pressing; In step S8, after the integrated paving and pressing, the raised and recessed parts of the edges need to be trimmed. The raised parts are directly smoothed with a polishing machine, and the recessed parts are coated with a sealant of the same color to keep the outer side of the bamboo board flat.

[0021] In the process of the novel recombinant structural bamboo board assembly method, the required bamboo raw materials are first prepared, four-year-old bamboo is selected, washed and dried, and cut into three lengths of 2520 mm, 2820 mm and 900 mm to 1250 mm, and then the bamboo can be processed by a chipping machine. During the processing, the root, middle section, tail and short tail of the bamboo need to be distinguished in order, and after the processing, each part needs to be arranged and processed according to the specifications of 3 pieces, 4 pieces, 5 pieces and 6 pieces. At this time, the bamboo chips can be loosened and made into transverse bamboo-based fibers 1. At the same time, it is necessary to perform a de-greening treatment to ensure color consistency, and the short tail of the bamboo needs to be brushed to process the part into a diameter range controlled at 0.5 mm to 1.5 mm. The circular bamboo filaments 2 between the two groups of circular bamboo filaments 2 can be separated and arranged up and down at this time, so that the horizontal bamboo-based fibers 1 are distributed at both ends of the two groups of circular bamboo filaments 2 distributed horizontally, and the internal fiber texture of the horizontal bamboo-based fibers 1 is perpendicular to the placement of the circular bamboo filaments 2. At the same time, the horizontal bamboo-based fibers 1 and the circular bamboo filaments 2 need to be glued, and then dried, and the moisture content inside the holder is about 15% to 18%, and then the pressing process can be performed. Before pressing, the green side of the horizontal bamboo-based fibers 1 needs to face down and the yellow side faces up, and the gap is filled after the horizontal bamboo-based fibers 1 and the circular bamboo filaments 2 are placed crosswise up and down, and after the pressing is completed, the raised parts of the bamboo board are ground, and the sunken parts are filled with glue to ensure the flatness of the bamboo board; The longitudinal tension of the round bamboo filaments is changed to lateral discharge to enhance the lateral tension. During the pressing process, the lateral bamboo-based fibers 1 wrap around the round bamboo filaments to form a strong wrapping tension, which is similar to the role of steel in building concrete. The advantage of this role is that it is not easy to crack, deform and delaminate. The round bamboo filaments are used as a bridge structure to solve the problem of insufficient lateral tension of the reconstructed bamboo board and improve the physical properties of the reconstructed material. In addition, the method focuses on solving the problem of insufficient lateral tension of heavy board assemblies, fills the gap in the industry, and increases the physical properties of the reconstructed board. The existing reconstructed bamboo board has insufficient lateral tension, while the longitudinal tension is very good. The mismatch between the two is also a pain point of the reconstructed board, which increases the overall practicality.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
