Description

Technical Field

[0001] This invention relates to the field of bamboo tableware manufacturing technology, and in particular to a method for manufacturing bamboo tableware. Background Technology

[0002] In recent years, with increasing environmental awareness, plastic pollution has attracted widespread attention. Traditional plastic tableware is widely used due to its convenience and low cost, but its non-biodegradable nature leads to serious environmental pollution. Microplastics enter soil and water bodies, threatening ecosystems and human health. Therefore, developing environmentally friendly and biodegradable alternatives has become an urgent problem to be solved.

[0003] Bamboo, as a fast-growing plant, possesses strong renewable and environmentally friendly characteristics. Its high density and moderate hardness, along with natural antibacterial and corrosion-resistant properties, make it suitable for tableware. Furthermore, bamboo is completely biodegradable in the natural environment, causing no secondary pollution. Therefore, "replacing plastic with bamboo" has become an effective way to replace traditional plastic tableware, promoting the sustainable development of the bamboo industry.

[0004] Currently, the manufacturing technology for bamboo tableware mainly involves processes such as peeling, cutting, grinding, shaping, and polishing the bamboo. The application of these processes has promoted the widespread use of bamboo tableware and solved the environmental pollution problems caused by plastic tableware. However, in actual production, at least the following problems still exist:

[0005] (1) Bamboo has poor adaptability, low utilization rate, and serious waste;

[0006] (2) Bamboo tableware has poor stability and is prone to mold and cracking;

[0007] (3) Bamboo tableware has poor consistency in appearance and performance, which affects the user experience. Summary of the Invention

[0057] This invention provides a method for manufacturing bamboo tableware, comprising the following steps: substrate treatment, anti-mildew treatment, blank forming, drying treatment, and subsequent shaping. Specifically, the substrate treatment includes the following steps: cutting raw bamboo into sections to obtain several bamboo tubes; screening and classifying the bamboo tubes according to different tableware types to obtain bamboo tubes to be processed for different tableware types; splitting the bamboo tubes to be processed for different tableware types (which can be done by sawing bamboo (not mechanical crushing or impact cracking)) to obtain curved bamboo strips to be processed for different tableware types; and processing the curved bamboo strips to be processed for different tableware types using an integrated milling and cutting process to obtain wide bamboo strips to be processed that meet the shape requirements of different tableware types.

[0058] Raw bamboo refers to bamboo that has been directly harvested, including the stubble (the root of the bamboo) and the tip (the top of the bamboo). This invention selects high-quality raw bamboo that is 4 years or older and free from insect infestation, odor, mold, and other pollution as raw materials to manufacture bamboo tableware, ensuring the naturalness, environmental friendliness, and durability of the products.

[0059] After being cut into sections, raw bamboo is cut into bamboo tubes of predetermined specifications. Specifically, the bamboo tubes are straight, with a length of 1.30 ± 0.02 m, a small-end diameter greater than 10 cm, and a thickness greater than 9 mm. Throughout the production process, the length, small-end diameter, and thickness of the bamboo tubes are strictly controlled to ensure that each tube meets the requirements for manufacturing bamboo tableware. Cutting raw bamboo into sections to obtain bamboo tubes of predetermined specifications helps optimize the stability and consistency of bamboo tableware in terms of appearance, strength, and durability.

[0060] In some optional embodiments, after the substrate treatment, the wide bamboo strips to be processed undergo an anti-mold treatment (food-grade anti-mold treatment may be used) to improve the long-term stability and antibacterial properties of the bamboo. Subsequently, the wide bamboo strips to be processed are milled using a contour milling process to obtain a basic blank that meets the shape requirements of different types of tableware. Next, the basic blank is dried to remove excess moisture. After the drying process is completed, the basic blank is further shaped, i.e., further processed, to obtain finished products of different types of tableware.

[0061] In some alternative embodiments, after substrate treatment, the wide bamboo strips to be processed are milled using laser cutting technology to obtain basic blanks that meet the shaping requirements of different types of tableware. These basic blanks can be bamboo knife blanks, bamboo fork blanks, and bamboo spoon blanks. Subsequently, the basic blanks undergo anti-mildew treatment to improve the long-term stability and antibacterial properties of the bamboo. Next, the basic blanks are dried to remove excess moisture. After drying, the basic blanks undergo further shaping, i.e., further processing, to obtain finished tableware of different types. These finished tableware can be finished bamboo knives, finished bamboo forks, and finished bamboo spoons. Finished bamboo knives require sharpening, while finished bamboo forks and spoons require molding, secondary drying, and polishing.

[0062] This invention provides a method for manufacturing bamboo tableware, comprising the following steps: Substrate treatment: Cutting raw bamboo into sections to obtain several bamboo tubes; Classifying and sorting the bamboo tubes according to different tableware types to obtain bamboo tubes suitable for different tableware types; Splitting the bamboo tubes suitable for different tableware types to obtain corresponding curved bamboo strips suitable for different tableware types; Processing the curved bamboo strips suitable for different tableware types using an integrated milling and slitting process to obtain wide bamboo strips that meet the design requirements of different tableware types; Anti-mildew treatment; Molding: Milling the wide bamboo strips using a contour milling process or laser cutting process to obtain basic blanks that meet the design requirements of different tableware types; Drying treatment: Drying the basic blanks; Subsequent shaping: Further processing the basic blanks to obtain finished products of different tableware types. This manufacturing method, by classifying and sorting several bamboo tubes and matching them according to the design requirements of different tableware types, improves the adaptability and utilization rate of bamboo materials and reduces resource waste. Meanwhile, the use of integrated milling and cutting processes, along with contour milling (or laser cutting), enhances the consistency of appearance and performance in similar bamboo tableware, optimizing the consumer experience. Furthermore, the combination of anti-mold and drying treatments strengthens the stability of the bamboo tableware, reducing the risk of cracking and mold. It should be further noted that this manufacturing method uses no adhesives or hardeners throughout the entire process, employing raw bamboo directly, making it economical and environmentally friendly, and meeting food-grade safety standards. This manufacturing method improves processing efficiency and finished product quality, enabling the industrialization and large-scale production of "bamboo-based" tableware.

[0063] In some optional embodiments, the bamboo tubes to be processed include, but are not limited to, bamboo tubes for knives and forks and bamboo tubes for spoons. Specifically, the bamboo tubes for spoons and bamboo tubes for knives and forks differ in size. The small-end diameter of the bamboo tube for spoons is larger than that of the bamboo tube for knives and forks, and the thickness of the bamboo flesh in the bamboo tube for spoons is also greater than that in the bamboo tube for knives and forks. More specifically, the small-end diameter of the bamboo tube for spoons is greater than 13.5 mm, and the bamboo flesh thickness is greater than 10 mm, while the small-end diameter of the bamboo tube for knives and forks is greater than 10 cm, and the bamboo flesh thickness is greater than 9 mm.

[0064] In some optional embodiments, the curved bamboo strips to be processed include, but are not limited to, curved bamboo strips for bamboo knives and forks and curved bamboo strips for bamboo spoons. Specifically, the curved bamboo strips for spoons and curved bamboo strips for bamboo knives and forks differ in size. The width of the curved bamboo strip for spoons is greater than that for curved bamboo strips for bamboo knives and forks, and the thickness of the bamboo flesh in the curved bamboo strip for spoons is also greater than that in the curved bamboo strips for curved bamboo strips for curved bamboo knives and forks. More specifically, the width of the curved bamboo strip for spoons is not less than 42 mm, and the thickness of the bamboo flesh is greater than 10 mm, while the width of the curved bamboo strip for bamboo knives and forks is not less than 32 mm, and the thickness of the bamboo flesh is greater than 9 mm.

[0065] In some optional embodiments, the wide bamboo strips to be processed include, but are not limited to, wide bamboo strips for bamboo knives and forks and wide bamboo strips for bamboo spoons. Specifically, the wide bamboo strips for bamboo knives and forks and the wide bamboo strips for bamboo spoons differ in size. The width of the wide bamboo strips for bamboo spoons is greater than that for bamboo knives and forks. More specifically, the width of the wide bamboo strips for bamboo spoons is 37±0.5mm to 40±0.5mm, and the thickness is 2.0±0.5mm, while the width of the wide bamboo strips for bamboo knives and forks is 27±0.5mm to 29mm±0.5mm, and the thickness is 2.0±0.5mm. It should be further noted that the wide bamboo strips to be processed are required to be free of defects such as residual bamboo yellow, bamboo green, cracks, and insect holes.

[0066] In some optional embodiments, the blank forming includes the following steps: bamboo knife blank forming, bamboo fork blank forming, and bamboo spoon blank forming, respectively forming the basic blanks of bamboo knife blank, bamboo fork blank, and bamboo spoon blank; bamboo knife blank forming includes sharpening the bamboo knife blank.

[0067] When using the contour milling process to mill wide bamboo strips, the width of each strip must be controlled, with a deviation not exceeding 1mm. In other words, the width of the bamboo strips before processing must be as uniform as possible to improve the dimensional consistency of the finished bamboo tableware. Excessive width variation will affect the appearance and performance of the bamboo tableware.

[0068] When using the contour milling process to mill wide bamboo strips, these strips need to be arranged according to certain rules or order, ensuring they are neatly aligned. This improves the stability and precision of the contour milling process, thereby enhancing the dimensional consistency of the finished bamboo tableware. If the bamboo strips are not arranged neatly, errors may occur during processing, affecting the dimensional consistency of the bamboo tableware.

[0069] When using the contour milling process to mill wide bamboo strips, the required length of the bamboo strips for making bamboo knives and forks is 1.30±0.02m, and the width is 27±0.5mm~29mm±0.5mm. It should be further noted that due to tool errors during contour milling and variations in the width of multiple wide bamboo strips, even with clamping and alignment, if the width of the bamboo strips is lower than the above requirements, defects such as missing edges, missing corners, or incomplete shapes may occur in the bamboo knife and fork blanks, leading to an increased scrap rate. Tests have shown that if the width of the bamboo strips for making bamboo knives and forks is lower than the above requirements, the scrap rate of the bamboo knife and fork blanks increases by more than 20%. Each wide bamboo strip for making bamboo knives and forks, after being milled using the contour milling process, yields multiple bamboo knife blanks, bamboo fork blanks, or combinations thereof. For example, each bamboo knife and fork is milled from a wide bamboo strip using a contour milling process to obtain 7 bamboo knife blanks, or 7 bamboo fork blanks, or a combination of 7 bamboo knife blanks and bamboo fork blanks.

[0070] When using the contour milling process to mill the wide bamboo strips to be processed, the required length of the wide bamboo strips for the bamboo spoons is 1.30 ± 0.02 m, and the width is 37 mm ± 0.5 mm. It should be further noted that due to tool errors during contour milling and variations in the width of the wide bamboo strips used for the bamboo spoons, even with clamping and alignment, if the width of the wide bamboo strips is lower than the above requirements, it may lead to defects such as missing edges, missing corners, or incomplete shapes in the bamboo spoon blanks, thus increasing the scrap rate. Tests have shown that if the width of the wide bamboo strips used for the bamboo spoons is lower than the above requirements, the scrap rate of the bamboo spoon blanks increases by more than 20%. Each wide bamboo strip used for the bamboo spoons, after being milled using the contour milling process, yields multiple bamboo spoon blanks. For example, each wide bamboo strip used for the bamboo spoons, after being milled using the contour milling process, yields 7 bamboo spoon blanks.

[0071] When using the contour milling process to mill wide bamboo strips, the anti-mold treatment step is performed before the blank forming step. This is because contour milling uses a wet processing method, while the anti-mold treatment involves ultrasonic treatment or slightly acidic electrolytic water treatment, followed by immersion in an anti-mold agent. After contour milling, the bamboo knife, fork, and spoon blanks do not require further soaking or washing in subsequent processing, effectively maintaining the stability and effectiveness of the anti-mold agent. If anti-mold treatment is performed after contour milling, additional washing, soaking, and drying are necessary, leading to agent loss and affecting the anti-mold effect. Therefore, a proper process sequence ensures the effectiveness of the anti-mold treatment and avoids unnecessary waste and quality loss.

[0072] Optionally, the drying kiln is dehumidified and dried before the drying process; the drying process includes the following steps: flexible drying of bamboo knife-shaped blanks, flexible drying of bamboo fork-shaped blanks and flexible drying of bamboo spoon-shaped blanks.

[0073] During the flexible drying of the bamboo knife blanks, the drying temperature was set at 45±5°C, and the drying time was 18±2 hours. Throughout the flexible drying process, the moisture content of the bamboo knife blank surface was monitored in real time and controlled below 5% to reduce problems such as deformation, cracking, and mold growth in the finished bamboo knives during subsequent use, thereby extending their shelf life. After milling and sharpening, the bamboo knife blanks only require drying and polishing before packaging.

[0074] During the flexible drying of bamboo fork-shaped and bamboo spoon-shaped blanks, the drying temperature was set at 45±5°C, and the drying time was 15±2 hours. During the flexible drying process, the moisture content of the bamboo fork-shaped and bamboo spoon-shaped blanks was monitored in real time, and the moisture content was controlled below 12±4%. Since the bamboo fork-shaped and bamboo spoon-shaped blanks need to undergo molding, their moisture content should be controlled at around 12±4%. Too low a moisture content will result in insufficient moisture in the bamboo during molding, leading to poor softening and increasing the risk of cracking in the molded areas. On the other hand, too high a moisture content will affect the deformation effect during molding, leading to increased springback deformation, which in turn affects the thoroughness of shaping, reduces the molding effect of the bamboo forks and spoons, and ultimately affects the overall quality of the product.

[0075] It should be further explained that, during the drying process, the warped bamboo knife-shaped blanks, bamboo fork-shaped blanks, and bamboo spoon-shaped blanks are selected and removed.

[0076] The subsequent shaping process includes the following steps: bamboo knife shaping, bamboo fork shaping, and bamboo spoon shaping.

[0077] Bamboo knife forming includes polishing with bamboo knife rollers, which use rollers with a volume of 0.5-1.0m³. 3The polishing drum is set with a polishing time of 40±5 minutes and a polishing speed of 15-20 r / min. To improve polishing efficiency and maintain a clean working environment, the polishing drum is equipped with a high-efficiency dust collection device, which can simultaneously polish and vacuum, effectively removing bamboo shavings and dust generated during the polishing process.

[0078] Bamboo fork forming includes bamboo fork molding, secondary drying, and bamboo fork roller polishing. During molding, the molding temperature is set at 140±5°C, the molding time at 25±5 seconds, and the molding pressure at 15-20T. Under these temperatures and pressures, the lower the cracking rate and the better the surface quality of the bamboo forks. During secondary drying, the drying temperature is set at 50±2°C, and the drying time at 3-4 hours. The moisture content of the molded bamboo fork blank is controlled below 5% to reduce deformation, cracking, and mold growth during subsequent use, thereby extending the shelf life of the finished bamboo forks. Bamboo fork roller polishing is similar to bamboo knife roller polishing and will not be elaborated further here.

[0079] The bamboo spoon forming process includes steam softening, molding, secondary drying, and roller polishing. Due to the significant deformation during molding, the bamboo spoons must first undergo steam softening before molding. The steam temperature is set at 110±5°C, and the softening time at 20±2 seconds. Experimental studies have shown that molding temperature and molding time significantly affect the molding effect. If the molding time is too short, excessive springback deformation will result in an unsatisfactory deformation effect, leading to incomplete shapes and severely impacting product quality. Therefore, the molding temperature is set at 140±5°C, the molding time at 25±5 seconds, and the molding pressure at 15-20T. During the secondary drying of the bamboo spoons, the drying temperature is set to 50±2°C, and the drying time is 3-4 hours. The moisture content of the bamboo spoon blanks after molding is controlled below 5% to reduce problems such as deformation, cracking, and mold growth in the finished bamboo spoons during subsequent use, thereby extending the shelf life of the finished bamboo spoons. The polishing of the bamboo spoon rollers is the same as that of the bamboo knife rollers, and will not be described in detail here.

[0080] Before milling the wide bamboo strips using laser cutting technology, the bamboo strips are soaked until they are saturated with water. During laser cutting, the laser power is set to 240-270W, the emission frequency to 100-120Hz, and the cutting speed to 20 pieces / min. When the laser power is below 240W, the cutting speed decreases, affecting processing efficiency; while when the power is above 270W, the cutting temperature is too high, causing the bamboo strips to burn and severely affecting the appearance quality. Experimental results show that setting the laser power to 240-270W, the emission frequency to 100-120Hz, and the cutting speed to 20 pieces / min yields the best cutting efficiency and surface quality. After laser milling, the basic blank undergoes a second soaking treatment, followed by turbine water jet cleaning to remove residual tar and impurities from the surface of the basic blank.

[0081] When using laser cutting technology to mill wide bamboo strips, the length of the bamboo strips is required to be 1.30±0.02m and the width is required to be 40mm±0.5mm. After each wide bamboo strip is milled by laser cutting technology, multiple basic blanks are obtained. For example, after each wide bamboo strip is milled by laser cutting technology, 5 sets of 10 basic blanks are obtained.

[0082] When using laser cutting technology to mill wide bamboo strips, the anti-mold treatment step is performed after the blank is formed to avoid high-temperature cutting damaging the activity of the anti-mold agent.

[0083] The integrated milling and slitting process includes the following steps: rough milling, uniform slitting, and finish milling. Rough milling is the first step in the slitting milling process, primarily used to remove excess material from the curved bamboo strips to be processed. Next, a uniform slitting step is performed, precisely dividing the rough-milled bamboo strips into several uniform shapes, ensuring consistent dimensions for each section. Finish milling is the final step of the entire process, designed to finely process the slitted and roughly milled bamboo strips, removing minor defects and burrs, resulting in a smoother and more polished surface, thus achieving higher appearance quality and dimensional accuracy.

[0084] The anti-mold treatment includes the following steps: Primary anti-mold treatment: Ultrasonic treatment is used to remove residual nutrients from the bamboo strips to be processed. The ultrasonic power is 500W, the temperature is 60℃, and the treatment time is 60 minutes. After ultrasonic treatment, the surface of the bamboo strips is washed with clean water for 30 minutes. Secondary anti-mold treatment: After the primary anti-mold treatment, the bamboo strips are soaked in a low-concentration food-grade anti-mold agent for 30 minutes.
