[0024] The present invention provides a method for producing bamboo tableware, comprising the following steps: substrate treatment, mildew-proof treatment, blank forming, drying treatment and subsequent forming. Specifically, substrate treatment comprises the following steps: sawing the original bamboo in sections to obtain a plurality of bamboo tubes; screening and classifying the plurality of bamboo tubes according to different tableware types to obtain bamboo tubes to be processed suitable for different tableware types; slicing the bamboo tubes to be processed suitable for different tableware types (slicing can be performed by sawing bamboo (not mechanical crushing or impact cracking)) to obtain curved bamboo pieces to be processed corresponding to different tableware types; processing the curved bamboo pieces to be processed suitable for different tableware types by an integrated milling and slitting process to obtain wide bamboo pieces to be processed that meet the modeling requirements of different tableware types.

[0025] Raw bamboo refers to bamboo that has been directly felled, including bamboo stumps (the root of bamboo) and bamboo shoots (the top of bamboo). The present invention uses high-quality raw bamboo that is 4 years old or older, free of insects, odor, mildew, and other pollution as raw materials to manufacture bamboo tableware, so as to ensure the naturalness, environmental protection, and durability of the products.

[0026] After the raw bamboo is sawn in fixed sections, bamboo tubes of preset specifications are obtained. Specifically, the bamboo tube has no bends, the length of the bamboo tube is 1.30±0.02m, the small end diameter of the bamboo tube is greater than 10cm, and the thickness of the bamboo tube is greater than 9mm. Throughout the production process, the length, small end diameter and thickness of the bamboo tube are strictly controlled to ensure that each bamboo tube meets the requirements and is suitable for the manufacture of bamboo tableware. By sawing the raw bamboo in fixed sections to obtain bamboo tubes of preset specifications, it helps to optimize the stability and consistency of the bamboo tableware in terms of appearance, strength and durability.

[0027] In some optional embodiments, after the substrate is treated, the wide bamboo pieces to be processed are subjected to mildew-proof treatment (food-grade mildew-proof treatment may be used) to improve the long-term stability and antibacterial properties of the bamboo material. Subsequently, the wide bamboo pieces to be processed are milled using a milling and profiling process to obtain a basic blank that meets the requirements of the shape of different tableware types. Next, the basic blank is dried to remove excess moisture. After the drying process is completed, the basic blank is subjected to subsequent molding, that is, further processing to obtain finished products of different tableware types.

[0028] In some other optional embodiments, after the substrate is processed, the wide bamboo pieces to be processed are milled by a laser cutting process to obtain a basic blank that meets the modeling requirements of different tableware types. Among them, the basic blank can be a bamboo knife blank, a bamboo fork blank and a bamboo spoon blank. Subsequently, the basic blank is subjected to mildew-proof treatment to improve the long-term stability and antibacterial properties of the bamboo. Next, the basic blank is dried to remove excess moisture. After the drying process is completed, the basic blank is subjected to subsequent molding, that is, further processing to obtain finished products of different tableware types. Among them, the finished products of different tableware types can be bamboo knife finished products, bamboo fork finished products and bamboo spoon finished products. The bamboo knife finished product needs to be sharpened, and the bamboo fork finished products and bamboo spoon finished products need to be molded, secondary dried, polished, etc.

[0029] The invention provides a method for producing bamboo tableware, comprising the following steps: substrate processing: sawing the original bamboo in sections to obtain a plurality of bamboo tubes; screening and classifying the plurality of bamboo tubes according to different tableware types to obtain bamboo tubes to be processed suitable for different tableware types; splitting the bamboo tubes to be processed suitable for different tableware types to obtain arc-shaped bamboo pieces to be processed corresponding to different tableware types; processing the arc-shaped bamboo pieces to be processed suitable for different tableware types by adopting a milling and slitting integration process to obtain wide bamboo pieces to be processed that meet the modeling requirements of different tableware types; mildew-proof treatment; blank molding: milling the wide bamboo pieces to be processed by adopting a milling and profiling process or a laser cutting process to obtain a basic blank that meets the modeling requirements of different tableware types; drying treatment: drying the basic blank; subsequent molding: further processing the basic blank to obtain finished products of different tableware types. The production method screens and classifies a plurality of bamboo tubes, matches the bamboo tubes according to the modeling requirements of different tableware types, improves the adaptability and utilization rate of bamboo materials, and reduces resource waste. At the same time, the use of integrated milling and slitting technology and engraving and profiling technology (or laser cutting technology) improves the consistency of appearance and performance of bamboo tableware of the same type, and optimizes the consumer experience. In addition, the combination of mildew-proof treatment and drying treatment enhances the stability of bamboo tableware and reduces the risk of cracking and mildew. It should be further explained that this production method does not use any adhesives or curing agents throughout the entire process. It uses raw bamboo for direct production, which is economical and environmentally friendly and meets food-grade safety standards. This production method improves processing efficiency and finished product quality, and realizes the industrialization and large-scale production of "bamboo instead of plastic" tableware.

[0030] In some optional embodiments, the bamboo tube to be processed includes but is not limited to a bamboo tube for bamboo knives and forks and a bamboo tube for bamboo spoons. Specifically, the bamboo tube for bamboo spoons and the bamboo tube for bamboo knives and forks are different in size. The small end diameter of the bamboo tube for bamboo spoons is larger than the small end diameter of the bamboo tube for bamboo knives and forks, and the bamboo flesh thickness of the bamboo tube for bamboo spoons is larger than the bamboo flesh thickness of the bamboo tube for bamboo knives and forks. More specifically, the small end diameter of the bamboo tube for bamboo spoons is larger than 13.5 mm, and the bamboo flesh thickness is larger than 10 mm, while the small end diameter of the bamboo tube for bamboo knives and forks is larger than 10 cm, and the bamboo flesh thickness is larger than 9 mm.

[0031] In some optional embodiments, the arc-shaped bamboo pieces to be processed include but are not limited to the arc-shaped bamboo pieces for bamboo knives and forks and the arc-shaped bamboo pieces for bamboo spoons. Specifically, the arc-shaped bamboo pieces for bamboo spoons and the arc-shaped bamboo pieces for bamboo knives and forks are different in size. The width of the arc-shaped bamboo pieces for bamboo spoons is greater than the width of the arc-shaped bamboo pieces for bamboo knives and forks, and the thickness of the bamboo flesh of the arc-shaped bamboo pieces for bamboo spoons is greater than the thickness of the bamboo flesh of the arc-shaped bamboo pieces for bamboo knives and forks. More specifically, the width of the arc-shaped bamboo pieces for bamboo spoons is not less than 42 mm, and the thickness of the bamboo flesh is greater than 10 mm, while the width of the arc-shaped bamboo pieces for bamboo knives and forks is not less than 32 mm, and the thickness of the bamboo flesh is greater than 9 mm.

[0032] In some optional embodiments, the wide bamboo pieces to be processed include but are not limited to wide bamboo pieces for bamboo knives and forks and wide bamboo pieces for bamboo spoons. Specifically, the wide bamboo pieces for bamboo knives and forks and the wide bamboo pieces for bamboo spoons are different in size. The width of the wide bamboo pieces for bamboo spoons is greater than the width of the wide bamboo pieces for bamboo knives and forks. More specifically, the width of the wide bamboo pieces for bamboo spoons is 37±0.5mm~40±0.5mm and the thickness is 2.0±0.5mm, while the width of the wide bamboo pieces for bamboo knives and forks is 27±0.5mm~29mm±0.5mm and the thickness is 2.0±0.5mm. It should be further explained that the wide bamboo pieces to be processed are required to be free of defects such as residual bamboo yellow, bamboo green, cracks, and worm holes.

[0033] In some optional embodiments, the blank molding includes the following steps: bamboo knife blank molding, bamboo fork blank molding and bamboo spoon blank molding, and the corresponding basic blanks formed are bamboo knife blank, bamboo fork blank and bamboo spoon blank respectively; the bamboo knife blank molding includes sharpening the bamboo knife blank.

[0034] When milling the wide bamboo pieces to be processed using the milling and profiling process, the width of each wide bamboo piece to be processed must be controlled, and the deviation cannot exceed 1mm. In other words, the width of the wide bamboo pieces to be processed must be as consistent as possible before processing to improve the consistency of the size of the processed bamboo tableware. If the width difference is too large, it will affect the appearance and performance of the bamboo tableware.

[0035] When the wide bamboo pieces to be processed are milled by the milling and profiling process, the wide bamboo pieces to be processed need to be arranged according to certain rules or sequences, and ensure that they are neatly aligned, so as to improve the stability and accuracy of the milling and profiling process, thereby improving the consistency of the size of the processed bamboo tableware. If the bamboo pieces are not arranged neatly, errors may occur during the processing, thus affecting the consistency of the size of the bamboo tableware.

[0036] When the wide bamboo pieces to be processed are milled by the milling and profiling process, the length of the wide bamboo pieces for bamboo knives and forks is required to be 1.30±0.02m, and the width is 27±0.5mm~29mm±0.5mm; it should be further explained that due to the error of the tool during the milling and profiling, and the difference in the width of multiple wide bamboo pieces for bamboo knives and forks, even if they are pressed and aligned, if the width of the wide bamboo pieces for bamboo knives and forks is lower than the above requirements, it may cause defects such as missing edges, missing edges or incomplete blanks of the bamboo knife and bamboo fork blanks, thereby increasing the scrap rate. Experiments have shown that if the width of the wide bamboo pieces for bamboo knives and forks is lower than the above requirements, the scrap rate of the bamboo knife and bamboo fork blanks will increase by more than 20%. After each wide bamboo piece for bamboo knives and forks is milled by the milling and profiling process, multiple bamboo knife blanks, bamboo fork blanks or one of their combinations are obtained. Exemplarily, each bamboo knife and fork is milled from a wide bamboo piece through a milling and profiling process to obtain 7 bamboo knife blanks, or 7 bamboo fork blanks, or a combination of 7 bamboo knife blanks and bamboo fork blanks.

[0037] When the wide bamboo piece to be processed is milled by the milling and profiling process, the length of the wide bamboo piece for the bamboo spoon is required to be 1.30±0.02m and the width is 37mm±0.5mm; it should be further explained that due to the error of the tool during the milling and profiling, and the difference in the width of the wide bamboo piece for the bamboo spoon, even if the pressing and alignment are performed, if the width of the wide bamboo piece for the bamboo spoon is lower than the above requirements, it may cause defects such as missing edges, missing edges or incomplete blanks of the bamboo spoon blank, thereby increasing the scrap rate. Experiments have shown that if the width of the wide bamboo piece for the bamboo spoon is lower than the above requirements, the scrap rate of the bamboo spoon blank increases by more than 20%. After each wide bamboo piece for the bamboo spoon is milled by the milling and profiling process, multiple bamboo spoon blanks are obtained. Exemplarily, after each wide bamboo piece for the bamboo spoon is milled by the milling and profiling process, 7 bamboo spoon blanks are obtained.

[0038] When the wide bamboo pieces to be processed are milled by the milling and profiling process, the anti-mildew treatment step is performed before the blank is formed. The reason is that the milling and profiling adopts a wet processing method, and the anti-mildew treatment adopts ultrasonic treatment or slightly acid electrolyzed water treatment, followed by soaking in a mildew inhibitor. After the milling and profiling treatment, the bamboo knife blank, bamboo fork blank and bamboo spoon blank do not need to be soaked in water, washed with water and other treatments in subsequent processing, thereby effectively maintaining the stability and mildew-proof effect of the mildew inhibitor. If the mildew-proof treatment is performed after the milling and profiling, additional washing, blistering and drying treatments are required, which will cause the mildew inhibitor to be lost and affect the mildew-proof effect. Therefore, a reasonable process sequence can ensure the effect of the mildew-proof treatment and avoid unnecessary waste and quality loss.

[0039] Optionally, before the drying process, the drying kiln is subjected to a dehumidification and drying process; the drying process includes the following steps: flexible drying of the bamboo knife blank, flexible drying of the bamboo fork blank and flexible drying of the bamboo spoon blank.

[0040] When the bamboo knife blank is flexibly dried, the drying temperature is set to 45±5°C and the drying time is set to 18±2h; during the flexible drying process of the bamboo knife blank, the moisture content of the bamboo knife blank surface is monitored in real time, and the moisture content of the bamboo knife blank is controlled below 5% to reduce deformation, cracking and mildew problems of the bamboo knife finished product during subsequent use, thereby extending the shelf life of the bamboo knife finished product. After the bamboo knife blank is processed by milling, profiling and sharpening, it only needs to be dried and polished before subsequent packaging.

[0041] During the flexible drying of the bamboo fork blank and the bamboo spoon blank, the drying temperature is set to 45±5°C and the drying time is set to 15±2h; during the flexible drying of the bamboo fork blank and the bamboo spoon blank, the moisture content of the bamboo fork blank surface and the bamboo spoon blank surface is monitored in real time, and the moisture content of the bamboo fork blank and the bamboo spoon blank is controlled below 12±4%. Since the bamboo fork blank and the bamboo spoon blank need to be molded, their moisture content should be controlled at about 12±4%. Too low a moisture content will cause the bamboo material to lack sufficient moisture during the molding process, resulting in poor softening effect, thereby increasing the risk of cracking in the molded part. On the other hand, too high a moisture content will affect the deformation effect during the molding process, resulting in aggravated rebound deformation, which in turn affects the thoroughness of the shaping, reduces the molding effect of the bamboo fork and the bamboo spoon, and ultimately affects the overall quality of the product.

[0042] It should be further explained that, while the drying process is in progress, the warped bamboo knife blanks, bamboo fork blanks and bamboo spoon blanks are selected and removed.

[0043] Subsequent forming includes the following steps: bamboo knife forming, bamboo fork forming and bamboo spoon forming.

[0044] Bamboo blade shaping includes bamboo blade roller polishing, which uses a volume of 0.5-1.0m 3 The polishing cylinder is set to polishing time of 40±5min and polishing speed of 15-20r / min. In order to improve the polishing efficiency and keep the working environment clean, the polishing cylinder is equipped with a high-efficiency dust collection device, which can realize dust collection while polishing, effectively removing the bamboo shavings and dust generated during the polishing process.

[0045] Bamboo fork molding includes bamboo fork compression molding, bamboo fork secondary drying and bamboo fork roller polishing. During bamboo fork compression molding, the molding temperature is set to 140±5°C, the molding time is set to 25±5s, and the molding pressure is set to 15-20T. At this molding temperature and molding pressure, the smaller the cracking rate of the bamboo fork, the better the surface quality. During the secondary drying of the bamboo fork, the drying temperature is set to 50±2°C, and the drying time is set to 3-4h. The moisture content of the bamboo fork blank after bamboo fork compression molding is controlled below 5% to reduce deformation, cracking and mildew of the finished bamboo fork during subsequent use, thereby extending the shelf life of the finished bamboo fork. The bamboo fork roller polishing refers to the bamboo knife roller polishing, which will not be repeated here.

[0046] Bamboo spoon forming includes bamboo spoon steam softening, bamboo spoon compression molding, bamboo spoon secondary drying and bamboo spoon roller polishing. In the bamboo spoon forming process, due to the large deformation of the molding, the bamboo spoon needs to be steam softened first and then compression molded. When the bamboo spoon is steam softened, the steam temperature is set to 110±5°C and the softening time is 20±2s. Through experimental research, it is found that the molding temperature and molding time have a significant effect on the molding effect. If the molding time is too short, the rebound deformation will be too large and the deformation effect will not be ideal, which will make the shape of the bamboo spoon product incomplete, seriously affecting the product quality. Therefore, when the bamboo spoon is compression molded, the molding temperature is set to 140±5°C, the molding time is 25±5s, and the molding pressure is 15-20T. During the secondary drying of the bamboo spoon, the drying temperature is set to 50±2°C and the drying time is 3-4h. The moisture content of the bamboo spoon blank after the bamboo spoon molding is controlled below 5% to reduce the deformation, cracking and mildew of the finished bamboo spoon during subsequent use, thereby extending the shelf life of the finished bamboo spoon. The roller polishing of the bamboo spoon refers to the roller polishing of the bamboo knife, which will not be repeated here.

[0047] Before the wide bamboo pieces to be processed are milled by laser cutting, the wide bamboo pieces to be processed are soaked until they are saturated with water. When the wide bamboo pieces to be processed are milled by laser cutting, the laser power is set to 240-270w, the emission frequency is 100-120Hz, and the cutting speed is 20 pieces / min. When the laser cutting power is lower than 240W, the cutting speed will decrease, thus affecting the processing efficiency; when the power is higher than 270W, the cutting temperature is too high, which will cause the bamboo pieces to burn black, seriously affecting the appearance quality. After experimental verification, when the laser power is set to 240-270W, the emission frequency is 100-120Hz, and the cutting speed is 20 pieces / min, the cutting efficiency and surface quality are both the best. After the wide bamboo pieces to be processed are milled by laser cutting, the basic blank is soaked for the second time, and then the tar and impurities remaining on the surface of the basic blank are removed by turbine water flow cleaning.

[0048] When the laser cutting process is used to mill the wide bamboo piece to be processed, the length of the wide bamboo piece is required to be 1.30±0.02m and the width is 40mm±0.5mm. After each wide bamboo piece is milled by the laser cutting process, a plurality of basic blanks are obtained. For example, after each wide bamboo piece is milled by the laser cutting process, 5 groups of 10 basic blanks are obtained.

[0049] When the laser cutting process is used to mill the wide bamboo pieces to be processed, the anti-mildew treatment step is performed after the blank is formed to avoid high-temperature cutting that destroys the activity of the anti-mildew agent.

[0050] The integrated milling and slitting process includes the following steps: rough milling, uniform slitting and fine milling. Among them, rough milling is the first step of the slitting and milling process, which is mainly used to remove the excess parts on the curved bamboo pieces to be processed. Next, the uniform slitting step is carried out to accurately divide the rough-milled bamboo pieces into several uniform shapes to ensure that the size of each part is consistent. Fine milling is the last step of the entire process, which aims to carefully process the slit and roughly milled bamboo pieces, remove tiny defects and burrs, and make the surface of the bamboo pieces smoother and brighter, thereby achieving higher appearance quality and dimensional accuracy.

[0051] The anti-mildew treatment includes the following steps: primary anti-mildew treatment: ultrasonic treatment is used to remove nutrients remaining on the wide bamboo pieces to be processed, wherein the power of the ultrasonic treatment is 500W, the temperature is 60°C, and the treatment time is 60 minutes; after the ultrasonic treatment, the surface of the wide bamboo pieces to be processed is washed with clean water for 30 minutes; secondary anti-mildew treatment: after the primary anti-mildew treatment, a low-concentration food-grade anti-mildew agent is used to soak the wide bamboo pieces to be processed for 30 minutes. It should be further explained that during the primary anti-mildew treatment, slightly acid electrolyzed water ultrasonic treatment can be used. During the secondary anti-mildew treatment, inorganic or organic food-grade anti-mildew agents can be used to soak the wide bamboo pieces to be processed.
