Description

Technical Field

[0001] This invention belongs to the field of corrugated pipe extrusion technology, and particularly relates to a corrugated pipe extrusion device. Background Technology

[0002] Recycling plastic waste is an important direction for achieving resource recycling. Among them, the process of processing plastic waste into corrugated pipes is widely used because it has both environmental and economic value.

[0003] However, existing corrugated pipe forming equipment for extruding plastic waste has many shortcomings in actual production: First, traditional equipment is mostly segmented, and the processes of raw material extrusion, traction guidance, cooling and shaping, defect detection, and winding and collection are not well connected, which not only leads to low processing efficiency, but also easily causes the plastic waste to melt instably due to process interruption, affecting the quality of corrugated pipe forming; Second, for corrugated pipes extruded from recycled plastic waste, the raised parts are prone to defects such as material shortage and cracks due to uneven melting of waste material, but existing testing institutions are mostly fixed-point testing, which cannot be adapted to the raised structure of corrugated pipes of different specifications, resulting in incomplete testing coverage, high defect omission rate, and difficulty in quickly recycling and reusing defective waste, causing resource waste; Third, the winding and collection process relies heavily on manual positioning and winding, which is not only labor-intensive, but also prone to problems such as loose stacking of corrugated pipes and large space occupation, resulting in poor convenience for subsequent transportation and reprocessing.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This equipment is suitable for the recycled extrusion molding of plastic waste. Through an integrated continuous process design of "extrusion-traction-cooling-detection-collection," it completes the entire process from melting and plasticizing plastic waste to corrugated pipe forming and collection without interrupting processing. Compared to traditional segmented processing equipment, it avoids manual transfer and waiting during process connections, significantly improving processing efficiency. Simultaneously, defective sections of corrugated pipe detected can be directly cut and recycled back to the extruder for remelting, effectively reducing plastic waste waste and significantly improving resource recycling rates, meeting the industry's green and environmentally friendly development needs. The traction component uses a design with two sets of traction belts and dual primary motors, allowing for precise control of motor speed to synchronize traction speed with extrusion. The machine's output speed is matched to ensure smooth traction of the corrugated pipe blank, avoiding problems such as uneven wall thickness and dimensional deviations caused by fluctuations in traction speed. Simultaneously, the second electric telescopic rod on the support plate allows for flexible adjustment of the support roller height, accommodating corrugated pipes of different diameters. This provides stable support and guidance for the freshly extruded high-temperature soft blank, preventing deformation due to its own weight and laying a solid foundation for subsequent forming quality. The cooling component temporarily stores cooling water through the connecting shell, and, in conjunction with multiple independently controllable cooling water pipes, achieves uniform spraying along the corrugated pipe axis. This quickly and evenly reduces the temperature of the high-temperature corrugated pipe blank, ensuring rapid blank shaping and avoiding problems such as residual internal stress and easy cracking caused by uneven cooling. The valve... The system features adjustable cooling water flow to meet the cooling needs of processing plastic waste of varying thicknesses and materials, further ensuring the structural stability and mechanical properties of the corrugated pipe after shaping. The defect detection component employs a ring-shaped electric slide rail with an adjustable angle and distance mounting ring, enabling the visual defect detector to perform continuous 360° circumferential inspection of the corrugated pipe's protrusions. Compared to traditional fixed-point inspection methods, this provides more comprehensive coverage and effectively avoids missing or hidden defects. Adjusting the mounting ring angle with a second motor and the detection distance with a first electric telescopic rod allows for precise adaptation to the structural characteristics of corrugated pipe protrusions of different specifications, improving inspection accuracy. Simultaneously, a marking spray gun can instantly mark defects upon detection, facilitating worker convenience. The system allows for rapid positioning and cutting, effectively reducing the risk of defective products flowing into subsequent processes and ensuring the quality of finished products. The collection component drives the collection cylinder to rotate via gear transmission, achieving automatic and uniform winding of the corrugated pipe without the need for manual winding. The guide rollers can compact the corrugated pipe in real time during the winding process, ensuring a tight fit after winding and significantly improving the storage space utilization of the collection cylinder. After winding, the first electric slide rail can lift the clamping plate and the wound corrugated pipe, making it convenient for workers to fit the entire corrugated pipe into the collection roller. Compared with the traditional stacking collection method, this not only avoids deformation and damage caused by messy stacking of corrugated pipes, but also greatly reduces the labor intensity of manual collection and facilitates subsequent transfer, storage, and reprocessing.

[0029] The operating principle of the present invention is now described as follows: When extruding corrugated pipes made from recycled plastic waste, the pre-treated plastic waste (crushed, washed, and dried) is first fed into the feed end of the extruder 1. The extruder 1 melts and plasticizes the plastic waste according to the thermoplastic material extrusion process. The discharge end of the extruder 1 continuously extrudes and forms corrugated pipe blanks. At this time, the operator first adjusts the extension and retraction of the second electric telescopic rod 56 on the support plate 55, which drives the U plate 57 and the support roller 58 to move up and down, so that the upper surface of the support roller 58 is precisely in contact with the lower surface of the corrugated pipe blank at the discharge end of the extruder 1, thereby providing auxiliary support for the freshly extruded high-temperature soft corrugated pipe blank and preventing the blank from deforming due to its own weight. Then, the operator uses tools to pull one end of the corrugated pipe blank from above the support roller 58 to between the two sets of traction belts 53 between the two fixed plates 51, ensuring that the blank is in the clamping center position of the two sets of traction belts 53. Two first motors 54 are started. The output of the first motor 54 drives one of the corresponding transmission wheels 52 to rotate. Through the transmission action of the traction belt 53, the other transmission wheel 52 in the same group rotates synchronously. The two sets of traction belts 53 rotate in the same direction at a linear speed that matches the discharge speed of the extruder 1, and smoothly pull the freshly extruded corrugated pipe billet into the cooling component 6 of the support frame 3. During the traction process, the support roller 58 always supports and guides the billet to ensure the straightness of the billet conveying trajectory. As the corrugated tube blank continues to enter the support frame 3 with the traction action, the workers connect the external cooling water supply pipeline to the connecting pipe 62 through the water pipe interface 63 of the connecting pipe 62, inject cooling water into the connecting shell 61, and then open multiple valves 64. The cooling water in the connecting shell 61 enters each cooling water pipe 65 through the valves 64. The cooling water pipes 65 spray cooling water evenly onto the surface of the blank along the axial direction of the corrugated tube blank, so as to achieve rapid cooling and shaping of the high temperature corrugated tube blank, meet the process requirements of rapid shaping after extrusion of thermoplastic materials, and at the same time ensure the uniformity of cooling. After cooling and shaping, the corrugated pipe possesses sufficient rigidity and continues to pass through the interior of the detection ring 71 with the traction action. At this time, the defect detection component 7 is activated to perform a comprehensive defect detection on the corrugated pipe protrusion (critical forming part): First, based on the tilt angle of the currently processed corrugated pipe protrusion, the second motor 75 on the slider 74 is activated to drive the first electric telescopic rod 76 to rotate the mounting ring 77, so that the axis of the mounting ring 77 is aligned with the tilt direction of the corrugated pipe protrusion; then, the first electric telescopic rod 76 is activated to extend and retract, driving the mounting ring 77 closer to the surface of the corrugated pipe, until the inner wall of the mounting ring 77 is in contact with the surface. The outer periphery of the corrugated pipe protrusion is completely covered. Then, multiple visual defect detectors 78 are activated to accurately detect defects such as material shortage, dents, cracks, and burrs that may occur on the outer protrusion of the corrugated pipe during the extrusion molding process. At the same time, the annular electric slide rail 73 is activated to drive the slider 74 to move in a circular motion along the inner wall of the detection ring 71. The moving speed of the slider 74 is precisely matched with the traction speed of the traction component 5 to ensure that the mounting ring 77 always moves synchronously with the moving corrugated pipe, so as to achieve 360° full circumference, continuous and uninterrupted detection coverage of the corrugated pipe protrusion. When the visual defect detector 78 detects a defect on the outer protrusion of the corrugated pipe, it immediately triggers the start of the marking spray gun 79 to spray red warning liquid onto the defect location, accurately marking the defect location. This makes it easier for subsequent staff to quickly locate the defective part, cut and separate the defective section of the corrugated pipe, and prevent the defective product from flowing into subsequent processes. At the same time, the cut-off defective plastic waste can be recycled to the feed end of the extruder 1 for remelting and processing, improving the utilization rate of plastic waste. After cooling and shaping and defect detection (or defect marking), the corrugated pipe is continuously moved out from one side of the support frame 3 with the traction action. Its end gradually falls to the collection component 8 below the support frame 3. When the end of the corrugated pipe moves to the side of the clamping plate 89, the worker puts the end of the corrugated pipe into the clamping area in the middle of the clamping plate 89, starts the third electric telescopic rod 810, drives the two clamping plates 811 to move relative to each other until the clamping plates 811 tightly clamp the end of the corrugated pipe, realizing the fixed limit of the end of the corrugated pipe. Then, the third motor 82 is started. The output end of the third motor 82 drives the first gear 83 to rotate. The first gear 83 drives the meshing second gear 84 to rotate synchronously, thereby driving the collection cylinder 85 fixedly connected to the second gear 84 to rotate. The corrugated pipe continuously moving out of the support frame 3 is evenly wrapped around the outside of the collection cylinder 85 under the rotation action of the collection cylinder 85. To improve the utilization rate of the storage space of the collection cylinder 85 and ensure that the wound corrugated pipe fits tightly (facilitating subsequent transportation and reprocessing), the fourth electric telescopic rod 816 is activated simultaneously during the winding process, driving the mounting plate 817, multiple support blocks 818, and guide rollers 819 to move towards the collection cylinder 85, so that the guide rollers 819 are positioned above the corrugated pipe wound around the outside of the collection cylinder 85; then the second electric slide rail 813 is activated, driving the second slide plate 814 downward until the guide rollers 819 are in close contact with the outermost corrugated pipe wall; subsequently, the fourth motor 815 is activated to drive... The moving mounting plate 817 drives multiple support blocks 818 and guide rollers 819 to rotate. During the rotation, the guide rollers 819 precisely contact the protrusions on the outside of the corrugated pipe, pressing down any loose parts that may occur during the winding process, so that the corrugated pipes of adjacent winding layers are tightly attached. During the winding process, the second electric slide rail 813 continuously drives the second slide plate 814 to move upward according to the increase of the corrugated pipe winding thickness, so that the guide rollers 819 always maintain contact with the outermost corrugated pipe, continuously compacting the newly wound corrugated pipe, ensuring that the entire roll of corrugated pipe is tightly wound, saving storage space; When the winding space on the surface of the collection cylinder 85 reaches saturation, the operator first cuts the corrugated tube outside the collection cylinder 85 near the defect detection component 7. The cut-off defective end section (if any) can be recycled to the extruder 1 for reuse. Then, a special collection roller is placed above the collection cylinder 85, and the first electric slide rail 87 is activated, which drives the first slide plate 88 and the clamping plate 89 to slide upward. The clamping plate 89 drives the bottom of the wound corrugated tube to move upward synchronously, so that the bottom of the corrugated tube is detached from the surface of the collection cylinder 85, making it easier for the operator to put the wound corrugated tube into the outside of the collection roller. After the tube is put in place, the third electric telescopic rod 810 is activated to reset, and the clamping plate 811 releases the clamp on the end of the corrugated tube, completing the collection operation of the corrugated tube. Afterward, the operator puts the cut new end of the corrugated tube back into the middle of the clamping plate 89 and repeats the above clamping, winding, and compaction steps to realize the continuous extrusion processing and collection of recycled corrugated tubes from plastic waste.
