Description

Technical Field

[0001] This invention relates to the field of bamboo fiber lunch box technology, specifically to a method for preparing an environmentally friendly and biodegradable bamboo fiber lunch box. Background Technology

[0002] In today's society, with people's increasing awareness of environmental protection, seeking sustainable solutions to replace traditional plastic products has become particularly important. Traditional disposable plastic lunch boxes are difficult to degrade after use, causing long-term pollution to the environment. Microplastics are present in every corner of the earth, including the deep ocean and the human body. In contrast, bamboo fiber lunch boxes can be completely degraded in the soil, which not only reduces environmental pollution but also improves soil fertility and has no adverse effects on soil pH or electrical conductivity. As a result, bamboo fiber lunch boxes are becoming increasingly popular as an environmentally friendly and biodegradable product.

[0003] However, in the preparation process of bamboo fiber lunch boxes, one step is to remove the green color from the harvested bamboo. Usually, for ease of operation, multiple bamboo stalks are stacked together for this process. While this stacking method saves space, it introduces a problem: the outer bamboo stalks, being in direct contact with the air, have better ventilation and are therefore removed faster; while the inner bamboo stalks, surrounded by other bamboo stalks, have poorer ventilation and are removed more slowly. This difference in ventilation causes the inner and outer layers of bamboo to be removed at different speeds. The outer bamboo stalks may have already been removed while the inner bamboo stalks are still slowly undergoing the removal process, which prolongs the overall removal time and reduces the preparation efficiency.

[0004] Therefore, it is necessary to provide a method for preparing environmentally friendly and biodegradable bamboo fiber lunch boxes to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0024] S3. Add a certain amount of waterproofing agent to bamboo fiber to improve the waterproof performance of the lunch box;

[0025] Step 7: Compression Molding

[0026] S1. Grind the processed bamboo fiber into a paste and pour it into a mold for initial shaping.

[0027] S2. Press the slurry using a press to shape it into the desired lunchbox shape.

[0028] S3. Cool and shape the pressed food containers to ensure they maintain the set shape.

When the adjustment block is slid so that it is not on the movement trajectory of the third button, pressing the third button will cause the connecting rod to squeeze the reset groove and move the limiting plate towards the sixth spring by an amount equal to the amount by which pressing the second button will cause the connecting rod to squeeze the second limiting groove and move the limiting plate towards the sixth spring.

[0054] The beneficial effects of this application are as follows: The method for preparing an environmentally friendly and biodegradable bamboo fiber lunch box provided by this application involves placing bamboo into multiple sets of placement slots, which separate the bamboo and prevent it from piling up. Then, by adjusting the working of the clamping component and disengaging the pushing component, the clamping component can hold the bamboo in the placement slots to prevent it from falling out. Furthermore, the U-shaped stacking rack ensures that all bamboo can be in direct contact with the air, resulting in good ventilation, increasing the speed of bamboo de-greening, and ensuring that all bamboo can be de-greened simultaneously, thereby reducing the overall de-greening time and improving the preparation efficiency.

[0055] After the bamboo is removed, the clamping component is deactivated by adjusting the adjustment mechanism, and the pushing component is activated. This allows all the bamboo in the placement slots on the stacking rack to be pushed out of the placement slots at the same time, so that the bamboo that has been removed can be collected at the same time, which is convenient for subsequent processes.

[0096] Step Nine: Packaging and Warehousing

[0097] The finished product is packaged for sale and use;

[0098] The stacking device in step two includes: a stacking base 1; a stacking rack 2, which is U-shaped and slidably disposed within the stacking base 1, and is provided in multiple sets; a placement slot 4, which is opened on the stacking rack 2 and is provided in multiple sets, for placing bamboo; a clamping component, disposed on the stacking rack 2, for clamping the bamboo in the placement slot 4; a pushing component, disposed within the stacking rack 2, for pushing the bamboo out of the placement slot 4; and an adjusting component, disposed within the stacking rack 2, for adjusting the working state of the clamping component and the pushing component.

[0099] In this embodiment: bamboo is placed into multiple sets of placement slots 4, which separate the bamboo and prevent it from piling up. Then, the clamping component is adjusted by adjusting the adjustment component and the pushing component is not working. At this time, the clamping component can hold the bamboo in the placement slots 4 to prevent the bamboo from falling. The U-shaped stacking rack 2 ensures that all bamboo can be in direct contact with the air, which is good for ventilation, increases the speed of bamboo removal, and ensures that all bamboo can be removed at the same time, which reduces the overall removal time and improves the preparation efficiency.

[0100] After the bamboo is removed, the clamping component is deactivated by adjusting the adjustment component, and the pushing component is activated. This allows all the bamboo inside the placement slots 4 on the stacking rack 2 to be pushed out of the placement slots 4 at the same time, so that the bamboo that has been removed can be collected at the same time, which is convenient for subsequent processes.

[0101] Specifically, such as Figure 3As shown, a drop groove 9 is provided on the stacking base 1, a drop box 3 is slidably provided on the bottom of the stacking base 1, a slide rail 6 is provided on the stacking base 1, and a slide groove 5 is provided at the corresponding position of the slide rail 6 on the stacking rack 2, and the slide groove 5 slides in cooperation with the slide rail 6.

[0102] In this embodiment: the drop trough 9 facilitates ventilation of the bamboo and allows the bamboo to fall into the drop box 3 after the bamboo has been de-greened, making it easy to collect the bamboo after de-greening. The stacking rack 2 can be disassembled or installed by the cooperation of the slide 5 and the slide rail 6, which makes it easy to adjust the gap between multiple stacking racks 2, and thus adjust the ventilation effect according to the degree of bamboo de-greening, ensuring that the bamboo can be de-greened at the same time.

[0103] Specifically, such as Figure 5 As shown, the clamping component includes a clamping groove 10, which is opened on both sides of each placement groove 4. A clamping block 11 is slidably disposed in the clamping groove 10. A first spring 12 is connected between the clamping block 11 and the clamping groove 10 to push the clamping block 11 out of the clamping groove 10.

[0104] In this embodiment, the bamboo in the placement slot 4 can be clamped by pushing the clamping block 11 out of the clamping slot 10 through the first spring 12, thus preventing the bamboo from falling.

[0105] Specifically, such as Figure 5 As shown, the pushing component includes a push groove 8, which is opened on the placement groove 4. A push block 7 is slidably disposed in the push groove 8. A fifth spring 22 is disposed between the push block 7 and the push groove 8 to push the push block 7 out of the push groove 8.

[0106] In this embodiment: the fifth spring 22 pushes the push block 7 out of the push groove 8, which can push the bamboo in the placement groove 4 out of the placement groove 4, thereby facilitating the collection of the bamboo after the greening is removed.

[0107] Specifically, such as Figure 5-9 As shown, the adjusting component includes a movable cavity 28, which is located on the top of the stacking rack 2. A first adjusting rod 24 is slidably disposed in the movable cavity 28. One end of the first adjusting rod 24 is connected to a first button 13. The first button 13 has a "T" shape, and the end of the first button 13 away from the first adjusting rod 24 is located on the outside of the stacking rack 2. A second spring 14 is disposed between the first button 13 and the stacking rack 2 to push the first button 13 away from the first adjusting rod 24. Both ends of the first adjusting rod 24 are connected to a first traction rope 23. The other end of the first traction rope 23 is provided with multiple branch ropes. Each branch rope passes through the bottom of the corresponding clamping groove 10 into the clamping groove 10 and is connected to the clamping block 11.

[0108] A second adjusting rod 25 is slidably disposed in the movable cavity 28. One end of the second adjusting rod 25 is connected to a second button 16. The second button 16 has a "T" shape, and the end of the second button 16 away from the second adjusting rod 25 is located on the outside of the stacking rack 2. A third spring 15 is disposed between the second button 16 and the stacking rack 2 to push the second button 16 away from the second adjusting rod 25. Both ends of the second adjusting rod 25 are connected to a second traction rope 27. The other end of the second traction rope 27 is provided with multiple branch ropes. Each branch rope passes through the bottom of the corresponding push groove 8 into the push groove 8 and is connected to the push block 7.

[0109] A third adjusting rod 26 is slidably disposed in the movable cavity 28. One end of the third adjusting rod 26 is connected to a third button 17. The third button 17 has a "T" shape, and the end of the third button 17 away from the third adjusting rod 26 is located on the outside of the stacking rack 2. A fourth spring 18 is disposed between the third button 17 and the stacking rack 2 to push the third button 17 away from the third adjusting rod 26. The ends of the first adjusting rod 24, the second adjusting rod 25 and the third adjusting rod 26 away from the first button 13 are all connected to a connecting rod 30, which has an "L" shape.

[0110] A limiting plate 29 is slidably disposed within the movable cavity 28 near the connecting rod 30. A sixth spring 31 connects the limiting plate 29 and the movable cavity 28 for resetting the limiting plate 29. A first limiting groove 2903 is provided on the limiting plate 29 at the position corresponding to the first adjusting rod 24. The first limiting groove 2903 includes a first holding groove and a first locking groove, which are connected. The first holding groove is an open groove with a bevel, and its open end faces the connecting rod 30. The first locking groove is rectangular. Pressing the first button 13 will cause the connecting rod 30 to squeeze the first holding groove, thereby moving the limiting plate 29 toward the sixth spring 31, so that the connecting rod 30 enters the first locking groove. A second limiting groove 2902 is provided on the limiting plate 29 at the position corresponding to the second adjusting rod 25. The second limiting groove 2902 includes a second holding groove and a second locking groove. The second holding groove is connected to the second locking groove. The second holding groove is an open groove with a bevel, and its open end faces the direction of the connecting rod 30. The second locking groove is rectangular. Pressing the second button 16 will cause the connecting rod 30 to squeeze the second holding groove, causing the limiting plate 29 to move towards the sixth spring 31, so that the connecting rod 30 enters the second locking groove. The depth of the first holding groove is equal to the depth of the second holding groove, and the width of the first holding groove is less than the width of the second holding groove. The depth of the first locking groove is equal to the depth of the second locking groove, and the width of the first locking groove is less than the width of the second locking groove. A reset groove 2901 is provided on the limiting plate 29 at the position corresponding to the third adjusting rod 26. The reset groove 2901 is an open groove, and the depth of the reset groove 2901 is equal to the depth of the second limiting groove 2902, and the width of the reset groove 2901 is equal to the width of the second limiting groove 2902.

[0111] The stacking rack 2 has an adjustment groove 21, and an adjustment block 19 is slidably disposed in the adjustment groove 21. An adjustment handle 20 is disposed on the side of the adjustment block 19 away from the third button 17. When the adjustment block 19 is slid so that it is on the movement trajectory of the third button 17, pressing the third button 17 will cause the connecting rod 30 to press the reset groove 2901 and move the limiting plate 29 towards the sixth spring 31 by an amount equal to the amount by which pressing the first button 13 will cause the connecting rod 30 to press the first limiting groove 2903 and move the limiting plate 29 towards the sixth spring 31. When the adjustment block 19 is not on the movement trajectory of the third button 17, pressing the third button 17 will cause the connecting rod 30 to press the reset groove 2901 and move the limiting plate 29 towards the sixth spring 31 by an amount equal to the amount by which pressing the second button 16 will cause the connecting rod 30 to press the second limiting groove 2902 and move the limiting plate 29 towards the sixth spring 31.

[0112] In this embodiment: Pressing the first button 13 causes the first adjusting rod 24 and the connecting rod 30 on the first adjusting rod 24 to press the first limiting groove 2903, thereby causing the limiting plate 29 to move towards the sixth spring 31 until the connecting rod 30 on the first adjusting rod 24 enters the first locking groove through the first pressing groove. At this time, the sixth spring 31 pushes the limiting plate 29 to reset, and the first locking groove cooperates with the connecting rod 30 on the first adjusting rod 24 to limit the first adjusting rod 24. Since the width of the first locking groove is smaller than the width of the second locking groove, the second locking groove still limits the connecting rod 30 on the second adjusting rod 25. At this time, the first adjusting rod 24 tightens the first traction rope 23, thereby causing the multiple clamping blocks 11 to be put into the clamping groove 10, which facilitates the placement of the placement groove 4.

[0113] By adjusting the handle 20, the adjusting block 19 is pushed to slide towards the third button 17 in the adjusting groove 21, so that the adjusting block 19 is on the movement trajectory of the third button 17. When the third button 17 is pressed, the third button 17 drives the third adjusting rod 26 and the connecting rod 30 on the third adjusting rod 26 to squeeze the reset groove 2901, and the third button 17 will be blocked by the adjusting block 19. At this time, the movement of the limiting plate 29 driven by the third adjusting rod 26 is equal to the movement of the limiting plate 29 driven by pressing the first button 13. Then the connecting rod 30 on the first adjusting rod 24 will enter the connection between the first locking groove and the first pressing groove. At this time, the second spring 14 pushes the first button 13 away from the first adjusting rod 24, so that the connecting rod 30 on the first adjusting rod 24 will disengage from the first limiting groove 2903, canceling the limitation on the first adjusting rod 24, and then the first traction rope 23 will be released. Then the first spring 12 can push the clamping block 11 to clamp the bamboo in the placement groove 4.

[0114] By adjusting the handle 20, the adjusting block 19 is pushed to slide away from the third button 17 in the adjusting groove 21, so that the adjusting block 19 is not on the movement trajectory of the third button 17. At this time, the third button 17 is pressed, and the third button 17 drives the third adjusting rod 26 and the connecting rod 30 on the third adjusting rod 26 to squeeze the reset groove 2901. At this time, the movement of the limiting plate 29 driven by the third adjusting rod 26 is equal to the movement of the limiting plate 29 driven by pressing the second button 16. Then, the connecting rod 30 on the second adjusting rod 25 will enter the connection between the second locking groove and the second pressing groove. At this time, the third spring 15 pushes the second button 16 away from the second adjusting rod 25, so that the connecting rod 30 on the second adjusting rod 25 disengages from the second limiting groove 2902, canceling the limitation on the second adjusting rod 25. Then, the second traction rope 27 is released, and the fifth spring 22 can push the third button 17 to push the bamboo in the placement groove 4 outward.

[0115] The specific solution is as follows: the stacking rack 2 is slidable by the sliding groove 5 and the sliding rail 6, so that the stacking rack 2 is separated from the stacking base 1. At this time, the stacking rack 2 can be laid flat on the ground, which is convenient for placing bamboo. First, press the second button 16. The second button 16 drives the second adjusting rod 25 and the connecting rod 30 on the second adjusting rod 25 to squeeze the second limiting groove 2902, thereby driving the limiting plate 29 to move towards the sixth spring 31 until the connecting rod 30 on the second adjusting rod 25 enters the second locking groove through the second pressing groove. At this time, the sixth spring 31 pushes the limiting plate 29 to reset. Then, the second locking groove and the connecting rod 30 on the second adjusting rod 25 cooperate to limit the second adjusting rod 25. At this time, the second adjusting rod 25 tightens the second traction rope 27, thereby causing multiple push blocks 7 to be put into the push groove 8.

[0116] Then press the first button 13, and the first button 13 will drive the first adjusting rod 24 and the connecting rod 30 on the first adjusting rod 24 to squeeze the first limiting groove 2903, thereby driving the limiting plate 29 to move towards the sixth spring 31 until the connecting rod 30 on the first adjusting rod 24 enters the first locking groove through the first pressing groove. At this time, the sixth spring 31 pushes the limiting plate 29 to reset, and the first locking groove and the connecting rod 30 on the first adjusting rod 24 cooperate to limit the first adjusting rod 24. Since the width of the first locking groove is smaller than the width of the second locking groove, the second locking groove still limits the connecting rod 30 on the second adjusting rod 25. At this time, the first adjusting rod 24 will tighten the first traction rope 23, thereby causing multiple clamping blocks 11 to be put into the clamping groove 10, which is convenient for placing the placement groove 4.

[0117] After the placement slot 4 is in place, the adjusting block 19 is pushed by the adjusting handle 20 to slide towards the third button 17 in the adjusting slot 21, so that the adjusting block 19 is on the movement trajectory of the third button 17. At this time, pressing the third button 17 will cause the third adjusting rod 26 and the connecting rod 30 on the third adjusting rod 26 to squeeze the reset slot 2901, and the third button 17 will be blocked by the adjusting block 19. At this time, the amount of movement of the limiting plate 29 driven by the third adjusting rod 26 is equal to the amount of movement of the limiting plate 29 driven by pressing the first button 13, and then the third... The connecting rod 30 on the first adjusting rod 24 will enter the connection between the first locking groove and the first pressing groove. At this time, the second spring 14 pushes the first button 13 away from the first adjusting rod 24, thereby causing the connecting rod 30 on the first adjusting rod 24 to disengage from the first limiting groove 2903, canceling the limiting of the first adjusting rod 24, and then releasing the first traction rope 23. Then the first spring 12 can push the clamping block 11 to clamp the bamboo in the placement groove 4. Through the cooperation of the sliding groove 5 and the sliding rail 6, the stacking rack 2 can be reinstalled on the stacking base 1, which is convenient for removing the green leaves from the bamboo.

[0118] After the greening is removed, the adjusting block 19 is pushed away from the third button 17 in the adjusting groove 21 by adjusting the handle 20, so that the adjusting block 19 is no longer on the movement trajectory of the third button 17. At this time, the third button 17 is pressed, and the third button 17 drives the third adjusting rod 26 and the connecting rod 30 on the third adjusting rod 26 to squeeze the reset groove 2901. At this time, the movement of the limiting plate 29 driven by the third adjusting rod 26 is equal to the movement of the limiting plate 29 driven by pressing the second button 16. Then, the connecting rod 30 on the second adjusting rod 25 will enter the connection between the second locking groove and the second pressing groove. At this time, the third spring 1 5. Push the second button 16 away from the second adjusting rod 25, thereby causing the connecting rod 30 on the second adjusting rod 25 to disengage from the second limiting groove 2902, canceling the limiting of the second adjusting rod 25, and then loosening the second traction rope 27. Then the fifth spring 22 can push the third button 17 to push the bamboo in the placement groove 4 outward. At this time, press the first button 13 again, which will drive multiple clamping blocks 11 into the clamping groove 10, canceling the clamping of the bamboo, ensuring that each bamboo is pushed out of the placement groove 4, and the bamboo falls into the dropping box 3 through the dropping groove 9, which is convenient for collecting the bamboo after the greening is completed.
