Description

Technical Field

[0001] This invention belongs to the field of negative carbon technology, specifically a negative carbon process for the resource utilization of bamboo and wood product waste. Background Technology

[0002] Mechanical painting robots utilize mechanical transmission components to perform painting operations. The arms have a large range of motion and can perform complex trajectory movements. Their wrists typically have 2 to 3 degrees of freedom, allowing for flexible movement. More advanced painting robots use flexible wrists that can bend and rotate in all directions, mimicking the movements of a human wrist. This allows them to easily reach into the interior of workpieces through small holes and spray their inner surfaces. They also offer advantages such as robustness and durability.

[0003] Utility model patent application CN211303540U discloses a special robotic arm for painting robots, relating to the field of painting technology. It includes a mobile base with a motor box at its upper end and a control component at its upper end. A first shaft is installed between the control component and the motor box, and a second shaft is installed at the upper end of the control component. A steering shaft is installed at the upper end of the second shaft. An atomizer atomizes the spraying material into fine mist particles, resulting in a more uniform and smooth coating surface, which is beneficial for increasing product added value. A splash guard prevents paint from splashing during spraying, polluting the air, and affecting the health of workers. An air compressor uses low-pressure air to atomize the paint after it exits the nozzle, applying it to the object surface. Compared to hand brushing, air spraying leaves no brush marks, produces a relatively uniform surface, has a shorter unit working time, effectively shortens the construction period, and has low investment costs.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] When coating is required on tubular bamboo and wood products or perforated tubular bamboo and wood products, the lack of a cleaning mechanism for the hole and tube walls can easily lead to dust covering the tube or hole walls during the spraying process, affecting the adhesion of the coating.

[0006] Therefore, this invention provides a negative carbon process for the resource utilization of bamboo and wood product waste. Summary of the Invention

[0018] A method for adjusting a carbon-negative process for the resource utilization of bamboo and wood product waste, using the linkage coating robotic arm as described in any one of claims 1-9, includes the following specific steps:

[0019] S1. When it is necessary to spray the inner wall or hole wall of tubular bamboo and wood products or hollow tubular bamboo and wood products, first place the base in the designated position, and then use the controller to operate it. First, start the eighth motor to drive the third gear to rotate, which will cause the first gear and the sliding column to rotate, thereby adjusting the horizontal angle of the support frame. Then start the first motor to drive the first threaded rod to rotate, causing the lifting block to slide up and down, thereby adjusting the height of the support frame. Then start the first hydraulic cylinder to drive the adjusting arm to move, thereby adjusting the distance between the support frame and the center of the base. Then start the second motor to drive the rotating block to rotate, thereby adjusting the angle of the support frame. Then start the second hydraulic cylinder to adjust the distance between the support frame and the rotating block. Using the above adjustment operations, the position of the linkage tubular bamboo and wood product cleaning component can be adjusted so that it extends into the interior of the tubular bamboo and wood product.

[0020] S2. After the linkage-type tubular bamboo and wood product cleaning component is inserted into the tubular bamboo and wood product, the distribution of dust on the inner wall of the tubular bamboo and wood product and the spraying situation are observed using monitoring equipment, so as to better carry out the spraying work and make the spraying and cleaning work more targeted; and make the turntable coincide with the axis of the tubular bamboo and wood product, adjust the orientation of the first nozzle, and then use the first pump body to draw out the paint from the first paint tank and spray it out after passing through the first nozzle, so that the paint is sprayed onto the inner wall of the tubular bamboo and wood product, thus spraying the inner wall of the tubular bamboo and wood product. At the same time, the third hydraulic cylinder can be activated to drive the frame to move radially, so that the brush roller is in contact with the inner wall of the tubular bamboo and wood product, and then the fourth motor is activated to drive the brush roller to rotate, thus cleaning the dust attached to the spraying position;

[0021] S3. When it is necessary to spray paint the holes of the hollowed-out tubular bamboo and wood products, the adjusting plate can be aligned with the holes with the cooperation of the second hydraulic cylinder and the third motor, and the axes of the two coincide. Since the brush plate is initially close to the second paint box, the leftmost part of the entire adjusting plate is within the diameter range of the brush roller. Therefore, at this time, only the brush roller can be in contact with the inner diameter of the tubular bamboo and wood products. So when it is necessary to spray paint the holes of the hollowed-out tubular bamboo and wood products, the fifth motor is started to drive the first connecting rod and the third... The two linkages rotate, causing the brush plate to move and align the brush tip with the hole wall. Then, the upper and lower limit rods simultaneously slide in opposite directions on the sliding sleeve and move away from each other, so that the brush tip of the brush plate abuts against the hole wall. Then, the sixth motor is started to drive the adjusting disc to rotate, which makes the brush plate rotate and clean the dust attached to the hole wall. After the dust falls off, the second pump body is started, which draws out the paint from the second paint tank and sprays it onto the hole wall through the first nozzle, thus realizing the spraying work on the hole wall.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The present invention discloses a negative carbon process for the resource utilization of bamboo and wood product waste. After placing the base in a designated position, the eighth motor is activated to drive the third gear to rotate, which in turn rotates the first gear and the sliding column, thus adjusting the horizontal angle of the support frame. Then, the first motor is activated to drive the first threaded rod to rotate, causing the lifting block to slide up and down, thereby adjusting the height of the support frame. Next, the first hydraulic cylinder is activated to move the adjusting arm, thus adjusting the distance between the support frame and the center of the base. Then, the second motor is activated to drive the rotating block to rotate, thus adjusting the angle of the support frame. Finally, the second hydraulic cylinder is activated to adjust the distance between the support frame and the rotating block. Using these adjustment operations, the orientation of the linkage-type tubular bamboo and wood product cleaning component can be adjusted, allowing it to extend into the interior of the tubular bamboo and wood product to perform coating work on the inner wall of the tubular bamboo and wood product, thereby improving the flexibility of the entire coating process.

[0024] 2. The carbon-negative process for the resource utilization of bamboo and wood product waste described in this invention involves the following steps: When the linkage-type tubular bamboo and wood product cleaning assembly extends into the interior of the tubular bamboo and wood product and aligns the turntable with the axis of the tubular bamboo and wood product, the orientation of the first nozzle can be adjusted to extract the paint from the first paint tank and spray it out through the first nozzle, thus spraying the paint onto the inner wall of the tubular bamboo and wood product. Simultaneously, the brush roller is brought into contact with the inner wall of the tubular bamboo and wood product. Then, the fourth motor is activated to rotate the brush roller, cleaning the dust adhering to the spraying area and preventing dust from obstructing the spraying efficiency. When it is necessary to spray the holes in the hollowed-out tubular bamboo and wood product, the fifth motor is activated to rotate the first and second connecting rods, causing them to... The change in the included angle between the components allows the brush plate to move, aligning the brush tip with the hole wall. Then, the seventh motor is activated, driving the second gear and third connecting rod to rotate. This causes the upper and lower limit rods to slide in opposite directions on the sliding sleeve, moving them away from each other. This brings the brush tip against the hole wall. Next, the sixth motor is activated, driving the adjusting disc to rotate, thus rotating the brush plate and cleaning the dust adhering to the hole wall. After the dust falls off, the second pump is activated, drawing paint from the second paint tank and spraying it onto the hole wall through the first nozzle. This achieves the spraying of the hole wall. Therefore, the dust adhering to the tube and hole walls of the perforated tubular bamboo and wood products can be cleaned before spraying, preventing dust from affecting the spraying effect.

[0025] 3. The negative carbon process for the resource utilization of bamboo and wood product waste described in this invention uses monitoring equipment to observe the distribution of dust on the inner wall of tubular bamboo and wood products and the spraying situation, thereby enabling better spraying work and making the spraying and cleaning work more targeted.

[0039] In this embodiment, as Figure 1 , Figure 7 , Figure 8 As shown, the robotic arm assembly includes a sliding column 3 rotatably mounted on the upper middle part of the base 1 via a rotating shaft. A lifting block 43 is slidably connected to the sliding column 3. A first telescopic rod 5 is fixedly connected to the rear side of the left end face of the lifting block 43.

[0043] Specifically, after placing the base 1 in the designated position, starting the eighth motor 44 drives the third gear 45 to rotate, which in turn rotates the first gear 30 and the sliding column 3, thereby adjusting the horizontal angle of the support frame 13. Then, starting the first motor 6 drives the first threaded rod 7 to rotate, causing the lifting block 43 to slide up and down, thereby adjusting the height of the support frame 13. Then, starting the first hydraulic cylinder 4 drives the adjusting arm 8 to move, thereby adjusting the distance between the support frame 13 and the center of the base 1. Then, starting the second motor 9 drives the rotating block 10 to rotate, thereby adjusting the angle of the support frame 13. Then, starting the second hydraulic cylinder 11 adjusts the distance between the support frame 13 and the rotating block 10. Using the above adjustment operations, the orientation of the linkage tubular bamboo and wood product cleaning component can be adjusted so that it extends into the interior of the tubular bamboo and wood product to perform coating work on the inner wall of the tubular bamboo and wood product, thereby improving the flexibility of the entire coating work.

[0044] In this embodiment, as Figures 2-6 As shown, a third motor 14 is fixedly connected to the upper end of the support frame 13, the output end of the third motor 14 is fixedly connected to the turntable 15, and a third hydraulic cylinder 16 is fixedly connected to the front side of the lower end of the turntable 15. The piston end of the third hydraulic cylinder 16 is fixedly connected to the frame 23.

[0045] A fourth motor 25 is fixedly connected to the lower end of the frame 23. The output end of the fourth motor 25 is fixedly connected to the brush roller 24. A fifth motor 26 is fixedly connected to the middle of the frame 23. The output end of the fifth motor 26 is fixedly connected to the first connecting rod 27. A sixth motor 31 is fixedly connected to the middle of the hinge block 29. The output end of the sixth motor 31 is fixedly connected to the adjusting plate 46. A second gear 36 and a third connecting rod 37 are rotatably arranged on both the upper and lower sides of the left end face of the adjusting plate 46. The second gears 36 on the upper and lower sides mesh with each other. A seventh motor 35 is fixedly connected to the left end of the adjusting plate 46. The output end of the seventh motor 35 is fixedly connected to the third connecting rod 37. A fourth connecting rod 34 is rotatably arranged at the end of the third connecting rod 37 away from the second gear 36. The end of the fourth connecting rod 34 away from the third connecting rod 37 is rotatably connected to the limiting rod 39.

[0046] The spraying assembly includes a first paint tank 18 fixedly connected to the right end face of the frame 23. The upper end of the first paint tank 18 is connected to a first conveying pipe 19. The left end of the first conveying pipe 19 is connected to a first pump body 20. The first pump body 20 is fixedly connected to the frame 23. The discharge end of the first pump body 20 is connected to a first nozzle 21. The upper side of the frame 23 is fixedly connected to a second paint tank 41. The lower middle part of the second paint tank 41 is connected to a second pump body 42. The discharge end of the second pump body 42 is connected to a second conveying pipe 32. The left ends of the second conveying pipe 32 are both connected to second nozzles 38. The second nozzles 38 are fixedly connected to an adjusting plate 46.

[0047] Specifically, after the linkage-type tubular bamboo and wood product cleaning component extends into the tubular bamboo and wood product and aligns the turntable 15 with the axis of the tubular bamboo and wood product, the third motor 14 is started to drive the turntable 15 to rotate, thereby adjusting the orientation of the first nozzle 21. Then, the first pump body 20 draws out the paint from the first paint tank 18 and sprays it out through the first nozzle 21, causing the paint to be sprayed onto the inner wall of the tubular bamboo and wood product, thus performing the spraying work on the inner wall of the tubular bamboo and wood product. At the same time, the third hydraulic cylinder 16 can be started to drive the frame 23 to move radially. The brush roller 24 is brought into contact with the inner wall of the tubular bamboo and wood product. Then, the fourth motor 25 is started to drive the brush roller 24 to rotate, which can clean the dust attached to the area to be sprayed and prevent the spraying efficiency from being affected by dust. When it is necessary to spray the holes of the hollowed-out tubular bamboo and wood product, the adjustment plate 46 can be aligned with the hole with the cooperation of the second hydraulic cylinder 11 and the third motor 14, and the two axes are coincident. Since the brush plate 33 is close to the second paint box 41 in the initial state, the leftmost part of the entire adjustment plate 46 is located at the brush roller. Within the diameter range of 24, only the brush roller 24 can be in contact with the inner diameter of the tubular bamboo and wood product. Therefore, when it is necessary to spray the holes of the hollowed-out tubular bamboo and wood product, the fifth motor 26 is started to drive the first connecting rod 27 and the second connecting rod 28 to rotate, so that the included angle between them changes, which can move the brush plate 33 and make the brush end of the brush plate 33 aligned with the hole wall. Then, the seventh motor 35 is started to drive the second gear 36 and the third connecting rod 37 to rotate, so that the upper and lower limit rods 39 can slide in opposite directions on the sliding sleeve 40 and move away from each other, so that the brush... The brush end of the brush plate 33 abuts against the hole wall, and then the sixth motor 31 is started to drive the adjusting plate 46 to rotate, so that the brush plate 33 can rotate to clean the dust attached to the hole wall. After the dust falls off, the second pump body 42 is started, and the second pump body 42 draws out the paint inside the second paint tank 41 and sprays it onto the hole wall after passing through the first nozzle 21, so as to realize the spraying work on the hole wall. In this way, the dust attached to the tube wall and hole wall of the hollow tubular bamboo and wood product can be cleaned first, and then sprayed, avoiding the situation where dust adheres to the tube wall and hole wall and affects the spraying effect.

[0048] In this embodiment, as Figures 1-8 As shown, a monitoring device 22 is installed on the upper left side of the frame 23, and a controller 2 is installed on the front left side of the upper surface of the base 1. The controller 2 is electrically connected to the monitoring device 22, the first motor 6, the second motor 9, the second hydraulic cylinder 11, the third motor 14, the third hydraulic cylinder 16, the first pump body 20, the fourth motor 25, the fifth motor 26, the sixth motor 31, the seventh motor 35, the second pump body 42, and the eighth motor 44.

[0049] Specifically, the upper front end of the controller 2 is equipped with a display screen for displaying the image of the monitoring device 22; the monitoring device 22 is used to observe the distribution of dust on the inner wall of the tubular bamboo and wood products and the spraying situation, and then the controller 2 is used to control the linkage adjustable tubular bamboo and wood product coating mechanism, so as to better carry out the spraying work and make the spraying and cleaning work more targeted.

[0050] Working Principle: When spraying coating on the inner wall or hole wall of tubular or perforated tubular bamboo and wood products, first place the base 1 in the designated position, then use the controller 2 for operation. First, start the eighth motor 44 to drive the third gear 45 to rotate, which will cause the first gear 30 and the sliding column 3 to rotate, thereby adjusting the horizontal angle of the support frame 13. Then, start the first motor 6 to drive the first threaded rod 7 to rotate, causing the lifting block 43 to slide up and down, thereby adjusting the height of the support frame 13. Then, start the first hydraulic cylinder 4 to drive the adjusting arm 8 to move, thereby adjusting the distance between the support frame 13 and the center of the base 1. Then, start the second motor 9 to drive the rotating block 10 to rotate, thereby adjusting the angle of the support frame 13. Finally, start the second hydraulic cylinder 4... The distance between cylinder 11, support frame 13, and rotating block 10 is adjusted. Using this adjustment, the orientation of the linkage-type tubular bamboo and wood product cleaning component can be adjusted so that it extends into the interior of the tubular bamboo and wood product. Once the linkage-type tubular bamboo and wood product cleaning component is inside the tubular bamboo and wood product, the distribution of dust on the inner wall of the tubular bamboo and wood product and the spraying situation are observed using monitoring device 22. This allows for better spraying and more targeted spraying and cleaning work. The turntable 15 is aligned with the axis of the tubular bamboo and wood product, and the orientation of the first nozzle 21 is adjusted. Then, the first pump body 20 draws out the paint from the first paint tank 18, which is then sprayed out through the first nozzle 21, causing the paint to be sprayed onto the tubular bamboo and wood product. The inner wall of the tubular bamboo and wood product can be sprayed. Simultaneously, the third hydraulic cylinder 16 can be activated to move the frame 23 radially, causing the brush roller 24 to fit against the inner wall of the tubular bamboo and wood product. Then, the fourth motor 25 is activated to rotate the brush roller 24, cleaning the dust adhering to the spraying area. When spraying the holes of the hollowed-out tubular bamboo and wood product, the second hydraulic cylinder 11 and the third motor 14 can be used to align the adjusting disc 46 with the holes, ensuring their axes coincide. Since the brush plate 33 is initially close to the second paint tank 41, the leftmost part of the adjusting disc 46 is within the diameter range of the brush roller 24. Therefore, only the brush roller 24 and the tubular bamboo and wood product can be sprayed at this time. The inner diameter fits snugly, so when it is necessary to spray the holes of the hollow tubular bamboo and wood products, the fifth motor 26 is started to drive the first connecting rod 27 and the second connecting rod 28 to rotate, so that the brush plate 33 moves and the brush end of the brush plate 33 is aligned with the hole wall. Then, the upper and lower limit rods 39 are driven to slide in opposite directions on the sliding sleeve 40 and move away from each other, so that the brush end of the brush plate 33 abuts against the hole wall. Then, the sixth motor 31 is started to drive the adjusting plate 46 to rotate, so that the brush plate 33 can rotate to clean the dust attached to the hole wall. After the dust falls off, the second pump body 42 is started. The second pump body 42 draws out the paint from the second paint tank 41 and sprays it onto the hole wall after passing through the first nozzle 21, so as to realize the spraying work on the hole wall.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

8. A coating process for bamboo and wood products, employing the bamboo and wood product coating apparatus described in claim 7, characterized in that, The specific steps include: S1. When it is necessary to spray the inner wall or hole wall of tubular bamboo and wood products or hollow tubular bamboo and wood products, first place the base (1) in the designated position, and then use the controller (2) to operate it. First, start the eighth motor (44) to drive the third gear (45) to rotate, which will make the first gear (30) and the sliding column (3) rotate, and thus adjust the horizontal angle of the support frame (13). Then start the first motor (6) to drive the first threaded rod (7) to rotate, which will make the lifting block (43) slide up and down, and thus adjust the support. Adjust the height of the support frame (13), then start the first hydraulic cylinder (4) to drive the adjustment arm (8) to move, so as to adjust the distance between the support frame (13) and the center of the base (1). Then start the second motor (9) to drive the rotating block (10) to rotate, so as to adjust the angle of the support frame (13). Then start the second hydraulic cylinder (11) to adjust the distance between the support frame (13) and the rotating block (10). By using the above adjustment operation, the position of the linkage tubular bamboo and wood product cleaning component can be adjusted so that it extends into the interior of the tubular bamboo and wood product. S2. When the linkage tubular bamboo and wood product cleaning component is inserted into the tubular bamboo and wood product, the monitoring equipment (22) is used to observe the distribution of dust on the inner wall of the tubular bamboo and wood product and the spraying situation, so that the spraying work can be carried out better and the spraying and cleaning work can be more targeted; and the turntable (15) is aligned with the axis of the tubular bamboo and wood product, the orientation of the first nozzle (21) is adjusted, and then the first pump body (20) is used to extract the paint inside the first paint box (18), and spray it out after passing through the first nozzle (21), so that the paint is sprayed onto the inner wall of the tubular bamboo and wood product, and the inner wall of the tubular bamboo and wood product can be sprayed. At the same time, the third hydraulic cylinder (16) can be started to drive the frame (23) to move radially, so that the brush roller (24) is in contact with the inner wall of the tubular bamboo and wood product, and then the fourth motor (25) is started to drive the brush roller (24) to rotate, so that the dust attached to the spraying position can be cleaned. S3. When it is necessary to spray the holes of the hollowed-out tubular bamboo and wood products, the adjustment plate (46) can be aligned with the holes with the cooperation of the second hydraulic cylinder (11) and the third motor (14), and the axes of the two coincide. Since the brush plate (33) is close to the second paint box (41) in the initial state, the leftmost part of the entire adjustment plate (46) is within the diameter range of the brush roller (24). Therefore, at this time, only the brush roller (24) can be in contact with the inner diameter of the tubular bamboo and wood products. So when it is necessary to spray the holes of the hollowed-out tubular bamboo and wood products, the fifth motor (26) is started to drive the first connecting rod (27) and the second connecting rod (28). Rotate the brush plate (33) to move the brush end of the brush plate (33) to align with the hole wall. Then drive the upper and lower limit rods (39) to slide in opposite directions on the sliding sleeve (40) and move away from each other, so that the brush end of the brush plate (33) abuts against the hole wall. Then start the sixth motor (31) to drive the adjustment plate (46) to rotate, so that the brush plate (33) can rotate and clean the dust attached to the hole wall. After the dust falls off, start the second pump body (42). The second pump body (42) draws out the paint inside the second paint tank (41) and sprays it onto the hole wall through the second nozzle (38), so that the spraying work on the hole wall can be realized.
