Description

Technical Field

[0001] This invention relates to the field of composite material manufacturing technology, specifically to a bamboo-based reinforced corrugated pipe manufacturing process and system. Background Technology

[0002] Corrugated pipes, due to their unique corrugated structure, possess excellent flexibility, compressive strength, and displacement compensation capabilities, making them widely used in building drainage, municipal engineering, and cable protection. Bamboo, as a renewable, biodegradable, and high-strength-to-weight-ratio natural fiber reinforcement material, can significantly improve the ring stiffness and environmental friendliness of corrugated pipes when used in their manufacture, aligning with sustainable development requirements.

[0003] However, the cooling and shaping process of bamboo-based reinforced corrugated pipes after extrusion or winding is a crucial step in ensuring the performance of the final product. Current technologies often employ water immersion or spray cooling for corrugated pipe cooling, which has the following significant drawbacks: First, the cooling process results in a single temperature field, with the pipe body rapidly cooling from a high temperature, leading to a large temperature difference between the inner and outer walls. This easily generates significant internal stress, causing product deformation, warping, and even micro-cracks, severely affecting dimensional accuracy and mechanical properties. Second, cooling medium residue often remains on the surface of the corrugated pipe after cooling. Third, traditional cooling methods consume a large amount of water, with the cooling medium (usually water) being directly discharged or simply circulated, resulting in poor temperature control accuracy, high energy consumption, and environmental disadvantages.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 like Figures 1-10As shown, this is the first embodiment of the present invention. This embodiment provides a bamboo-based reinforced corrugated pipe manufacturing system, including a cooling and drying module 5. The cooling and drying module 5 includes a cooling and shaping component 501, a wiping and drying component 502, and a conveying pipe 2. The cooling and shaping component 501 and the wiping and drying component 502 are connected through the conveying pipe 2. The inner cavity of the cooling and shaping component 501 is fixedly connected with multiple heat-insulating layered plates 26, which are divided into interconnected pre-cooling chambers, deep-cooling chambers, and uniform temperature chambers. Each chamber is equipped with a transmission sub-assembly for conveying the corrugated pipe. At the bottom of 501, there is a liquid storage sub-assembly 34 that is connected to each chamber. Each chamber is equipped with a spraying sub-assembly that can spray cooling medium onto the bellows. The cooling and shaping assembly 501 is externally equipped with a pre-cooling section temperature control sub-assembly 901, a deep-cooling section temperature control sub-assembly 902, and a uniform temperature section temperature control sub-assembly 903 that are connected to the spraying sub-assemblies and the liquid storage sub-assembly 34 in the corresponding chambers through pipes. These sub-assemblies are used to independently control the temperature of the cooling medium in each chamber so as to perform gradient cooling and shaping of the bellows and to circulate the cooling medium. The inlet of the wiping and drying assembly 502 is fixedly connected to a first wiping sub-assembly 8. The first wiping sub-assembly 8 has multiple wiping rollers 32 that can rebound and contact the outer wall of the corrugated pipe. The wiping and drying assembly 502 has a first square plate 131 and a second square plate 132 that are symmetrically fixedly connected inside. The outer sides of the first square plate 131 and the second square plate 132 are respectively slidably connected to wiping rollers 38 that can roll and wipe the outer wall of the corrugated pipe.

[0023] It should be noted that in this embodiment, the corrugated pipe first enters the pre-cooling chamber, deep-cooling chamber, and uniform-temperature chamber of the cooling and shaping assembly 501, which is separated by the heat-insulating layered plate 26. It is conveyed by the transmission sub-assembly and sprayed by the spraying sub-assemblies of each chamber with cooling medium that has been independently temperature-controlled by the pre-cooling section temperature control sub-assembly 901, deep-cooling section temperature control sub-assembly 902, and uniform-temperature section temperature control sub-assembly 903, achieving gradient cooling and shaping. The cooling medium is recycled by the liquid storage sub-assembly 34. Subsequently, the corrugated pipe enters the wiping and drying assembly 502 via the conveying pipe 2. It is first initially wiped by the wiping roller 32 in the first wiping sub-assembly 8, and then finely wiped by the wiping rollers 38 on the first square plate 131 and the second square plate 132.

[0024] The liquid storage sub-assembly 34 has multiple independent liquid storage tanks 35 inside, and each liquid storage tank 35 is respectively for recovering the cooling medium of the pre-cooling chamber, the deep cooling chamber and the uniform temperature chamber; the cooling shaping assembly 501 is fixedly connected to the liquid storage sub-assembly 34 by a water permeable plate 20, and the cooling shaping assembly 501 has a trapezoidal water drop trough 27 at the bottom of the water permeable plate 20 inside the water permeable plate 20, which is connected to the liquid storage tank 35.

[0025] It should be noted that in this embodiment, the cooling medium sprayed onto the corrugated pipe passes through the permeable plate 20 and flows into the corresponding independent liquid storage tanks 35 in the liquid storage sub-assembly 34 via the trapezoidal water drop trough 27, thereby realizing the classified recycling of cooling media in different temperature ranges and laying the foundation for precise temperature control and recycling.

[0026] The spray sub-assembly includes a semi-circular spray bar 23 and a circular column spray bar 24; The bottom of the semi-circular spray bar 23 is symmetrically and fixedly connected to a square linkage block 25 that communicates with it. The square linkage block 25 is rotatably connected to the inner wall of the cooling and shaping component 501. The circular column spray bar 24 is fixedly connected to the top of the permeable plate 20.

[0027] It should be noted that in this embodiment, within the cooling chamber, the cooling medium is sprayed onto the surface of the bellows via a semi-circular spray rod 23 and a circular cylindrical spray rod 24. The semi-circular spray rod 23 can be rotated via a square linkage block 25 to change the spray angle, ensuring uniform cooling coverage.

[0028] The top outlets of the precooling section temperature control sub-assembly 901, the cryogenic section temperature control sub-assembly 902, and the uniform temperature section temperature control sub-assembly 903 are respectively fixedly connected to a first connecting pipe 10 and a second connecting pipe 11. Both the first connecting pipe 10 and the second connecting pipe 11 extend into the interior of the cooling and shaping assembly 501 and are respectively connected to the square linkage block 25 and the circular column spray rod 24 in the corresponding chamber. The bottom inlets of the precooling section temperature control sub-assembly 901, the cryogenic section temperature control sub-assembly 902, and the uniform temperature section temperature control sub-assembly 903 are all fixedly connected to a third connecting pipe 12. The third connecting pipe 12 extends into the liquid storage sub-assembly 34 and is connected to the corresponding liquid storage tank 35. Control valves are installed inside the first connecting pipe 10, the second connecting pipe 11, and the third connecting pipe 12.

[0029] It should be noted that in this embodiment, the cooling medium is pumped from each temperature control sub-component to the spray bar of the corresponding chamber through the first connecting pipe 10 and the second connecting pipe 11. After the medium is used, it is recovered to the storage tank 35 and then drawn back to the temperature control sub-component through the third connecting pipe 12 for temperature regulation. The control valve is used to precisely manage the flow of each branch, thereby forming a complete and controllable closed-loop cooling system.

[0030] A protective frame 7 is fixedly connected to the outside of the cooling and shaping assembly 501. A third motor 16 is installed on the outside of the protective frame 7. The output shaft of the third motor 16 extends into the inside of the protective frame 7 and is connected to a second gear 18. The second gear 18 is rotatably connected to the cooling and shaping assembly 501. A first gear 17 is also symmetrically rotatably connected to the outside of the cooling and shaping assembly 501. A transmission toothed belt 19 meshes with the outside of the first gear 17 and the second gear 18 and forms a wrap angle. The connecting shafts of the first gear 17 and the second gear 18 both extend into the inside of the cooling and shaping assembly 501 and are fixedly connected to the square linkage block 25 in the corresponding cavity.

[0031] It should be noted that in this embodiment, the third motor 16 drives the square linkage block 25 and the semi-circular spray bar 23 connected thereto to rotate slowly through the transmission system consisting of the second gear 18, the transmission belt 19 and the first gear 17, thereby achieving dynamic spraying and further improving the uniformity of cooling. The protective frame 7 serves a safety protection function.

[0032] The transmission subassembly includes a mounting frame 21 and a transmission roller 22; The mounting frame 21 is fixedly connected to the top of the permeable plate 20, and the transmission roller 22 is symmetrically rotated and connected to the mounting frame 21 to support and transmit the corrugated pipe.

[0033] It should be noted that in this embodiment, the bellows is supported and conveyed in the cooling and shaping assembly 501 by the transmission roller 22 mounted on the mounting frame 21, and smoothly passes through the precooling chamber, the deep cooling chamber and the temperature equalization chamber in sequence.

[0034] The first wiping assembly 8 is externally fixedly connected to multiple round tubes 14. Each round tube 14 is internally slidably connected to a sliding cylindrical rod 15. The sliding cylindrical rod 15 can extend into the interior of the first wiping assembly 8 and is fixedly connected to an elastic squeezing block 30. A spring 29 is fixedly connected between the elastic squeezing block 30 and the inner wall of the first wiping assembly 8. An arc-shaped abutment block 31 is fixedly connected to the side of the elastic squeezing block 30 near the conveying pipe 2. The wiping roller 32 is fixedly connected to the outside of the elastic squeezing block 30 and is close to the arc-shaped abutment block 31. The end of the arc-shaped abutment block 31 that can contact the corrugated pipe has a certain curvature.

[0035] It should be noted that in this embodiment, when the bellows enters the first wiping component 8, it first contacts the arc-shaped abutment block 31. Under the action of the spring 29, the elastic squeezing block 30 and the sliding cylindrical rod 15 keep the wiping roller 32 in close contact with the outer wall of the bellows, adapting to its contour and effectively removing most of the cooling medium.

[0036] The first square plate 131 and the second square plate 132 are symmetrically and longitudinally connected to strip-shaped sliding plates 33. The outer sides of the strip-shaped sliding plates 33 are symmetrically provided with strip-shaped sliding grooves 36. The outer sides of the strip-shaped sliding plates 33 are symmetrically and fixedly connected to racks 37. The racks 37 can be inserted into the strip-shaped sliding grooves 36 on the opposite side. The outer sides of the first square plate 131 and the second square plate 132 are symmetrically and longitudinally rotatably connected to third gears 39. The third gears 39 mesh with the racks 37 on both sides. The wiping roller 38 is rotatably connected to the strip-shaped sliding plates 33.

[0037] It should be noted that in this embodiment, when the strip sliding plate 33 is driven, the rack 37 on it drives the third gear 39 to rotate, thereby driving the strip sliding plate 33 on the symmetrical side to move synchronously in opposite directions, so that the wiping roller 38 installed on the strip sliding plate 33 can always symmetrically press the bellows and perform balanced and thorough rolling wiping.

[0038] The top and outer side of the wiping and drying assembly 502 are respectively equipped with a first motor 4 and a second motor 6. The output shaft of the first motor 4 extends into the interior of the wiping and drying assembly 502 and is connected to a first threaded transmission rod. The first threaded transmission rod is threadedly connected to a strip sliding plate 33 on one side of the surface of the second square plate 132. The output shaft of the second motor 6 extends into the interior of the wiping and drying assembly 502 and is connected to a second threaded transmission rod. The second threaded transmission rod is threadedly connected to a strip sliding plate 33 on one side of the surface of the first square plate 131. An air supply component 3 for drying the surface moisture of the corrugated pipe is installed on the external side of the wiping and drying component 502, and a ventilation window 1 is installed on the external side of the wiping and drying component 502 corresponding to the air supply component 3.

[0039] It should be noted that in this embodiment, the first motor 4 drives the longitudinally arranged wiping roller 38 to move through the first threaded transmission rod, and the second motor 6 drives the transversely arranged wiping roller 38 to move through the second threaded transmission rod, thereby realizing the movement of the wiping roller 38 in the transverse and longitudinal directions, fully covering the outer wall of the corrugated pipe; before fine wiping, the corrugated pipe is first dried by the airflow generated by the air supply component 3, and the ventilation window 1 ensures air circulation, accelerates moisture evaporation, and improves the overall drying efficiency.

[0040] A manufacturing process for bamboo-based reinforced corrugated pipes, employing the aforementioned bamboo-based reinforced corrugated pipe manufacturing system, includes the following steps: S1: The formed bamboo-based reinforced corrugated pipe is sent into the pre-cooling chamber of the cooling and shaping component 501; S2: The temperature of the cooling medium in the precooling chamber is controlled by the precooling section temperature control sub-assembly 901 to perform preliminary cooling on the bellows; S3: The bellows enters the cryogenic chamber and the homogenization chamber in sequence. The temperature of the cooling medium in the corresponding chamber is controlled by the cryogenic section temperature control sub-assembly 902 and the homogenization section temperature control sub-assembly 903 respectively, so as to achieve gradient cooling and shaping of the bellows. S4: After cooling and shaping, the corrugated pipe enters the first water-wiping sub-assembly 8 inside the wiping and drying assembly 502 through the conveying pipe 2, and most of the cooling medium on the surface is removed by the water-wiping roller 32. S5: The corrugated pipe enters the air supply assembly 3, where the cooling medium is dried by the air force. Then, it passes through the center of the first square plate 131 and the second square plate 132, and the first motor 4 and the second motor 6 drive the wiping roller 38 to move laterally and longitudinally, so as to thoroughly wipe the remaining cooling medium on the outer wall of the corrugated pipe. S6: The wiped corrugated pipe is conveyed to the next process to complete the manufacturing.
