Description

Technical Field

[0001] This invention relates to the field of bamboo product processing technology, specifically to a method for processing bamboo tea trays. Background Technology

[0002] Originally used for holding and transferring tea, tea trays have become an indispensable part of teaware in modern society. Besides holding teaware, they also serve a function of storing water for brewing and rinsing tea. Tea trays also have an aesthetic appeal, with diverse shapes, sizes, and materials. Among the various materials used for tea trays, metal trays are the simplest and most durable, wooden trays offer the most varied designs, stone trays are the easiest to clean, and bamboo trays are the lightest and most convenient. While bamboo tea trays are elegant, affordable, and lightweight, the material itself makes them prone to cracking when too dry and mold when too damp.

[0003] In existing technologies, bamboo tea trays have a monotonous texture, lacking three-dimensional depth, and their surface is prone to moisture absorption and deformation, and lacks antibacterial properties. To overcome this monotony, laser engraving or surface coating is required. However, with prolonged use, the textured or engraved patterns quickly wear down on the bottom of the teacup, and these worn areas are prone to absorbing moisture and mold. While high-temperature carbonization or coating with chemical preservatives can improve the bamboo's crack and mold resistance, the former can lead to brittle bamboo fibers and reduced strength, making them more susceptible to wear from the rough bottom of the teacup, while the latter poses environmental risks and leaves residual odors.

[0004] The aforementioned problems also contribute to the short lifespan of bamboo tea trays. Therefore, a processing method for bamboo tea trays is needed to overcome these technical issues and extend their lifespan. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a bamboo tea tray processing method that can extend the service life of bamboo tea trays.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A method for processing bamboo tea trays includes: Bamboo is machined into tea tray blanks, which include a horizontal bottom surface, a top surface, and a side surface; the top surface is provided with a shaped groove. After polishing the tea tray blank, apply a primer to all surfaces of the tea tray blank and then dry it for the first time. After the first drying, polish it again, clean it for the first time, and then dry it for the second time. After the second drying, a primary blank is formed by water transfer printing on the top and sides of the irregular shape to create a water transfer printing layer. The primary billet is cleaned a second time by a conveying and cleaning device; The conveying and cleaning device includes a body, a conveyor belt, a conveyor motor, a circulating pump, a pressurizing pump, and a rotary motor. The body includes an inlet and an outlet, and a circulating water tank containing a viscous cleaning solution is installed inside the body. The conveyor belt is mounted on the body, passing through the inlet and exiting through the outlet. The conveyor belt is a loop belt, and the upper part of the conveyor belt during operation is the working section. The conveyor motor drives the upper layer of the conveyor belt from the inlet to the outlet. The body includes a spray zone and a pressurized rinsing zone, with the spray zone located near the inlet and the pressurized rinsing zone near the outlet. The spray zone has multiple spray nozzles, and the pressurized rinsing zone has several pressurized spray pipes located above the working section. The pressurized spray pipes are rotated by the rotary motor, and the rotation of the pressurized spray pipes is perpendicular to the length direction of the conveyor belt. The spray nozzles and the circulating water tank are connected through the circulating pump, and the pressurized spray pipes and the circulating water tank are connected through the pressurizing pump. The second cleaning process includes: placing the horizontal bottom surface of the primary blank on the working section, conveying it by a conveyor belt, and spraying the shaped tank with cleaning solution through the spray nozzle for immersion; when the primary blank enters the pressurized rinsing area, the rotary motor operates, causing the jet generated by the pressurized nozzle to rotate back and forth between 45° and 90° with the working surface. The 90° position is the initial position, and the 45° position is the final position. When the initial position turns to the final position, the pressurized pump operates.

[0007] Preferably, after the second cleaning is completed, the product is sent out through the outlet for the third and fourth cleaning. The fourth cleaning is followed by the third drying. After the third drying, the irregular top and side surfaces, or all surfaces, are sprayed with a transparent polytetrafluoroethylene coating and then dried and shaped a fourth time.

[0008] Preferably, the thickness of the water transfer printing layer is 0.08-0.12 mm.

[0009] Preferably, the jet water pressure generated by the pressurized nozzle is 0.6MPa-0.9MPa, and the temperature of the cleaning fluid is 20℃-35℃.

[0010] Preferably, a funnel-shaped collection trough is provided in the machine body below the conveyor belt, and the collection trough is connected to the circulating water tank.

[0011] Preferably, a filter screen is provided inside the collection tank.

[0012] Preferably, the circulating water tank is provided with a sampling port.

[0013] Preferably, the pressurized rinsing area is separated from the spray area and the outlet by flexible shielding curtains.

[0014] Preferably, there are at least three spray nozzles, which are respectively arranged on the machine body of the spray area on the left, right and top of the working part.

[0015] Preferably, the conveyor belt is a stainless steel perforated annular belt.

[0016] The beneficial effects of this invention are as follows: A shaped groove is formed on the top surface, which is not connected to the horizontal bottom surface or other sides to form a water outlet channel. This shaped groove, lacking a water outlet channel, can hold the cleaning liquid in the spray area. Due to its viscosity, the cleaning liquid adheres to the sides and top surface. The spray nozzles fill the shaped groove with cleaning liquid for immersion, effectively soaking, softening, and dissolving impurities and fragments in the water transfer printing. The full coverage of the cleaning liquid creates pressure on the water transfer printing layer, further compressing any existing air bubbles. The pressurized pump only operates when the initial position changes to the final position, creating a unidirectional (from outlet to inlet) flow that pushes the air bubbles to the side, preventing the back-and-forth rotation of the water flow from causing the air bubbles to be pushed back and forth and unable to escape. The pressurized fluid effectively soaks and softens the impurities and fragments. The process involves washing away dissolved impurities and debris, while the oscillating jet of fluid extrudes and squeezes out air bubbles. The existing cleaning fluid in the shaped tank disperses the fluid pressure, preventing direct impact that could burst the bubbles and increase the defect rate. Combined with the conveyor belt, any bubbles present are moved in the opposite direction (outlet direction) by the high-pressure fluid, aiding in their expulsion. The cleaning fluid's viscosity also helps to adhere to the side surfaces, forming a thin film that reduces the impact of the jet. When bubbles are squeezed out of the shaped tank and reach the side, the jet's direction (vertical or downward) forces them downwards. The overflowing cleaning fluid from the shaped tank protects the bubbles, preventing them from being directly burst, thus ensuring a high final product yield. Furthermore, the third and fourth cleaning cycles remove the remaining cleaning fluid. Finally, a transparent polytetrafluoroethylene (PTFE) coating is formed to ensure that the pattern can be displayed normally. PTFE is wear-resistant, high-temperature resistant, and moisture-resistant, making it well-suited to the working environment of the bamboo tea tray and preventing the bottom of the ceramic teacup from wearing down the water transfer layer. Furthermore, the bamboo tea tray itself does not require any other processing, which can reduce the odor caused by processing. Attached Figure Description

[0018] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1 to 3 A method for processing bamboo tea trays, comprising: Bamboo is machined into tea tray blanks, which include a horizontal bottom surface, a top surface, and a side surface; the top surface is provided with a shaped groove. After polishing the tea tray blank, apply a primer to all surfaces of the tea tray blank and then dry it for the first time. After the first drying, polish it again, clean it for the first time, and then dry it for the second time. After the second drying, a primary blank is formed by water transfer printing on the top and sides of the irregular shape to create a water transfer printing layer. The primary billet is cleaned a second time by a conveying and cleaning device; The conveying and cleaning device includes a body 1, a conveyor belt, a conveyor motor 2, a circulating pump 3, a pressurizing pump 4, and a rotary motor 5. The body 1 includes an inlet 11 and an outlet 12. A circulating water tank 13 is installed inside the body 1, and the circulating water tank 13 contains a viscous cleaning solution. The conveyor belt is mounted on the body 1 and passes through the inlet 11 and exits through the outlet 12. The conveyor belt is a ring belt, and the upper part of the conveyor belt is the working section when it is working. The conveyor motor 2 drives the upper part of the conveyor belt to move from the inlet 11 towards the outlet 12. Inside the body 1... The system includes a spray zone 14 and a pressurized rinsing zone 15. The spray zone 14 is located near the inlet 11, and the pressurized rinsing zone 15 is located near the outlet 12. The spray zone 14 has multiple spray nozzles 16, and the pressurized rinsing zone 15 has several pressurized spray pipes 17 located above the working section. The pressurized spray pipes 17 are rotated by a rotary motor 5, and the rotation of the pressurized spray pipes 17 is perpendicular to the length direction of the conveyor belt. The spray nozzles 16 and the circulating water tank 13 are connected by a circulating pump 3, and the pressurized spray pipes 17 and the circulating water tank 13 are connected by a pressurized pump 4. The second cleaning process includes: placing the horizontal bottom surface of the primary blank on the working section, conveying it by a conveyor belt, and spraying the shaped tank with cleaning solution through the spray nozzle 16 for immersion; when the primary blank enters the pressurized rinsing zone 15, the rotary motor 5 operates, causing the jet generated by the pressurized nozzle 17 to rotate back and forth between 45° and 90° with the working surface. The 90° position is the initial position, and the 45° position is the final position. When the initial position turns to the final position, the pressurized pump 4 operates.

[0020] As described above, a shaped groove is provided on the top surface. This groove is not connected to the horizontal bottom surface or other sides to form a water outlet channel. The shaped groove can hold the cleaning liquid in the spray area 14. Due to its viscosity, the cleaning liquid can adhere to the sides and top surface. The spray nozzle 16 sprays the shaped groove with the cleaning liquid for immersion, which can soak, soften, and dissolve impurities and fragments in the water transfer printing. The sprayed cleaning liquid can create pressure on the water transfer printing layer, thereby further squeezing out any existing air bubbles. The pressurized pump only works when the initial position changes to the final position, which can form a unidirectional (from the outlet direction to the inlet direction) force to squeeze the air bubbles to the side, avoiding the problem of the air bubbles being pushed back and forth and unable to be discharged due to the back-and-forth rotation of the water flow. The pressurized fluid can soak and soften the impurities and fragments. The dissolved impurities and fragments are washed away, and the oscillating jet of the fluid can squeeze out the bubbles. The original cleaning liquid in the shaped tank can disperse the fluid pressure, preventing the bubbles from bursting due to direct impact, thus increasing the defect rate. With the conveyor belt, once bubbles are present, they can move in another direction under the impact of the high-pressure fluid, assisting in the discharge of bubbles. Furthermore, due to the viscosity of the cleaning liquid, it can adhere to the side surface, forming a thin film, reducing the impact effect of the jet. When the bubbles squeezed out of the shaped tank reach the side, since the jet direction is vertically downward or inclined downward, it can squeeze the bubbles downward. The cleaning liquid overflowing from the shaped tank can protect the bubbles, preventing them from being directly broken, ensuring the final product yield. Furthermore, the cleaning liquid can be washed away through the third and fourth cleaning. 2. The bamboo tea tray processing method according to claim 1, characterized in that, after the second cleaning, it is sent out through outlet 12 for the third and fourth cleaning; The fourth cleaning is followed by the third drying. After the third drying, the irregular top and side surfaces, or all surfaces, are sprayed with a transparent polytetrafluoroethylene coating and then dried and shaped a fourth time.

[0021] As described above, a transparent polytetrafluoroethylene (PTFE) coating is finally formed to ensure that the pattern can be displayed normally. PTFE is wear-resistant, high-temperature resistant, and moisture-resistant, making it well-suited to the working environment of the bamboo tea tray and preventing the bottom of the ceramic teacup from wearing down the water transfer layer. Furthermore, the bamboo tea tray itself does not require any other processing, which can reduce the odor caused by processing.

[0022] Furthermore, the thickness of the water transfer printing layer is 0.08-0.12 mm.

[0023] As can be seen from the above description, a thicker water transfer film can be more resistant to impact and prevent it from being torn.

[0024] Furthermore, the jet water pressure generated by the pressurized nozzle 17 is 0.6MPa-0.9MPa, and the temperature of the cleaning fluid is 20℃-35℃.

[0025] As can be seen from the above description, due to the use of a thicker water transfer printing layer, the advantage of the thick film is its strong tear resistance, and it is more convenient to use high-pressure water rinsing to squeeze out air bubbles.

[0026] Furthermore, a funnel-shaped collection trough 18 is provided inside the machine body 1 below the conveyor belt, and the collection trough 18 is connected to the circulating water tank 13.

[0027] As can be seen from the above description, the funnel-shaped collection tank 18 facilitates the rapid return of the cleaning fluid to the circulation system, thereby reducing the overall amount of cleaning fluid used.

[0028] Furthermore, a filter screen 19 is provided inside the collection tank 18.

[0029] As can be seen from the above description, impurities can be filtered quickly by setting up filter screen 19.

[0030] Furthermore, the circulating water tank 13 is provided with a sampling port 131.

[0031] As can be seen from the above description, the cleaning solution can be sampled and tested regularly through the sampling port 131, and it can be replaced in time if it is found to be deteriorated or unable to meet the cleaning requirements.

[0032] Furthermore, the pressurized flushing zone 15 is separated from the spray zone 14 and the outlet 12 by flexible shielding curtains 6.

[0033] As can be seen from the above description, the flexible shielding curtain 6 can prevent high-pressure jets from being drawn. Furthermore, there are at least three spray nozzles 16, which are respectively arranged on the body 1 of the spray area 14 on the left, right and top of the working part.

[0034] As can be seen from the above description, by arranging multiple spray nozzles 16 on the left, right and top of the working part, it can be ensured that the top and sides of the water transfer printing area can be cleaned by the cleaning solution.

[0035] Furthermore, the conveyor belt is a stainless steel perforated annular belt.

[0036] As can be seen from the above description, the stainless steel perforated ring belt allows for easy and rapid drainage of the cleaning fluid; stainless steel is also more resistant to corrosion from the cleaning fluid.

[0037] Example 1 A method for processing bamboo tea trays includes: Bamboo is machined into tea tray blanks, which include a horizontal bottom surface, a top surface, and side surfaces. The top surface has a shaped groove that does not form a drainage channel with other surfaces, making it convenient to hold cleaning liquid. After polishing the tea tray blank, apply a primer to all surfaces of the tea tray blank and then allow it to dry for the first time; After the first drying, polish again, clean for the first time, and dry a second time; After the second drying, the horizontal bottom surface is held in place by a suction cup, and the primary blank is processed by water transfer printing on the irregular top and sides to form a water transfer printing layer. The thickness of the water transfer printing layer is 0.08-0.12mm. The thickness is selected according to different water transfer printing patterns or requirements. The thicker the water transfer printing, the greater the pressure output by the subsequent pressurizing pump 4, that is, the greater the jet water pressure.

[0038] The primary billet is cleaned a second time by a conveying and cleaning device; The conveying and cleaning device includes a body 1, a conveyor belt, a conveyor motor 2, a circulating pump 3, a pressurizing pump 4, and a rotary motor 5; The machine body 1 includes an inlet 11 and an outlet 12. A circulating water tank 13 is provided inside the machine body 1. The circulating water tank 13 contains a viscous cleaning solution with a temperature of 20℃-35℃. A sampling port 131 is provided on the circulating water tank 13.

[0039] The conveyor belt is mounted on the machine body 1, passing through inlet 11 and outlet 12. The conveyor belt is a stainless steel perforated ring belt, and the upper part of the conveyor belt is the working part when it is working. The conveyor motor 2 drives the upper layer of the conveyor belt to move from inlet 11 toward outlet 12. The machine body 1 is provided with a spray zone 14 and a pressurized rinsing zone 15. The spray zone 14 is located near inlet 11, and the pressurized rinsing zone 15 is located near outlet 12. The pressurized rinsing zone 15 is separated from the spray zone 14 and outlet 12 by flexible shielding curtains 6.

[0040] The spray zone 14 is provided with at least three spray nozzles 16, which are respectively arranged on the body 1 of the spray zone 14 on the left, right and top of the working part. Centrifugal spray nozzles 16 or rotatable spray heads can also be used to expand the coverage area by rotation, as long as the top and sides of the tea tray blank can be sprayed.

[0041] The pressurized rinsing zone 15 has several pressurized nozzles 17 located above the working section. These nozzles 17 are rotated by a rotary motor 5, and their rotation is perpendicular to the length of the conveyor belt. The spray nozzles 16 and the circulating water tank 13 are connected by a circulating pump 3, and the pressurized nozzles 17 and the circulating water tank 13 are connected by a pressurized pump 4. The jet water pressure generated by the pressurized nozzles 17 is 0.6 MPa-0.9 MPa. A funnel-shaped collection trough 18 is installed inside the machine body 1 below the conveyor belt, and this collection trough 18 is connected to the circulating water tank 13. A filter screen 19 is installed inside the collection trough 18.

[0042] The second cleaning process includes: placing the horizontal bottom surface of the primary blank on the working section, conveying it by a conveyor belt, and spraying the shaped tank with cleaning solution through the spray nozzle 16 for immersion; when the primary blank enters the pressurized rinsing zone 15, the rotary motor 5 operates, causing the jet generated by the pressurized nozzle 17 to rotate back and forth between 45° and 90° with the working surface. The 90° position is the initial position (vertical state), and the 45° position is the final position (rotating 45° from the vertical state towards the inlet side). When the initial position turns to the final position, the pressurized pump 4 operates, while when the final position turns to the initial position, the pressurized pump 4 does not operate, and the speed at which the final position turns to the initial position is higher than the speed at which the initial position turns to the final position.

[0043] After the second cleaning is completed, the solution is sent out through outlet 12 for the third and fourth cleaning to remove any remaining cleaning solution. The fourth wash is followed by the third drying (air drying); After the third drying, the irregular top and side surfaces, or all surfaces, are sprayed with a transparent polytetrafluoroethylene coating to form a fourth drying and shaping process.

[0044] Whether or not the horizontal bottom surface needs to be sprayed depends on the needs of the customer. If the customer requires it, then it will be sprayed.

[0045] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
