Description

Technical Field

[0001] The present invention relates to the technical field of crushing, and particularly relates to a recycling and crushing device for processing packaging cartons. Background Art

[0002] With the continuous improvement of environmental awareness and the increasing importance of resource recycling and utilization, the recycling and treatment of packaging cartons have become a field of great concern. In the current recycling process of packaging cartons, there are a series of problems to be solved.

[0003] The traditional equipment has a relatively single way of processing the crushed cartons. Usually, only simple crushing operations are carried out without humidifying the cartons. This makes the carton fragments easy to break and fly during subsequent processing, affecting the quality and efficiency of the recycling and treatment. As a result, the volume of the recycled paper scraps is relatively large, which is not convenient for storage, transportation, and subsequent reuse. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: A recycling and crushing device for processing packaging cartons, comprising: a processing box, a crushing shell is fixedly connected to the top of the processing box, a crushing roller is rotatably connected inside the crushing shell, a feed hopper is fixedly connected to the top of the crushing shell, and a discharge pipe is fixedly connected to the outside of the processing box; a spraying device for humidifying the crushed cartons, the outside of the spraying device is fixedly connected to the outside of the crushing shell, and the spraying device is located on the top of the processing box; an extrusion device for compressing the crushed and humidified cartons, the extrusion device is located inside the processing box, and a telescopic cylinder is fixedly connected to the inner wall of the processing box, and the output end of the telescopic cylinder is fixedly connected to the outside of the extrusion device; a blanking device, the outside of the blanking device is fixedly connected to the bottom of the crushing shell, the outside of the blanking device is fixedly connected to the inner wall of the processing box, and the blanking device is located on the top of the extrusion device; the spraying device includes a water storage tank, a water inlet pipe is fixedly connected to the top of the water storage tank, a connecting pipe is fixedly connected to the bottom of the water storage tank, the bottom end of the connecting pipe is fixedly connected to a confluence shell, a diffusion component is fixedly connected to the outside of the confluence shell, and a pressure increasing valve is fixedly connected to the outside of the connecting pipe; the blanking device includes a baffle plate, a bearing plate is fixedly connected to the bottom of the baffle plate, guide rails are slidably connected to both sides of the baffle plate, a guide rod is fixedly connected to the outside of the baffle plate, a fixing plate is slidably connected to the outer wall of the guide rod, and a compression spring is fixedly connected to the outside of the fixing plate; the extrusion device includes a mounting plate, a pushing plate is fixedly connected to the top of the mounting plate, an assembly frame is fixedly connected to the inner side of the mounting plate, and an extrusion roller is rotatably connected to the inner side of the assembly frame. The packaging cartons to be recycled are put into the crushing shell from the feed hopper. The crushing roller inside the crushing shell is driven by an external motor to rotate, and the cartons are crushed. At this time, the blanking device is in a closed state, and the crushed carton fragments are accumulated at the bottom of the crushing shell. Subsequently, the telescopic cylinder extends, so that the pushing plate in the extrusion device displaces in the processing box, contacts the bearing plate at the same time, and pushes the bearing plate to drive the baffle plate to displace. At this time, the baffle plate slides along the guide rail and approaches the fixing plate, and the compression spring outside the guide rod is compressed under force during the sliding process, so that the blanking device can be opened, and the crushed paper scraps fall into the processing box.

[0005] Preferably, the outside of the water storage tank is fixedly connected to the outside of the crushing shell, the outer wall of the connecting pipe is fixedly connected to the inner wall of the processing box, and the outside of the confluence shell is fixedly connected to the inner wall of the processing box. Water flows into the confluence shell through the connecting pipe and is finally sprayed out through the diffusion component, which can uniformly humidify the crushed cartons.

[0006] Preferably, a guiding plate is rotatably connected to the top of the baffle plate, a limiting plate is rotatably connected to the top of the guiding plate, an anti-blocking and dredging frame is fixedly connected to the outside of the guiding plate, both sides of the limiting plate are slidably connected to the inner wall of the crushing shell, and the bottom of the crushing shell is slidably connected to the top of the baffle plate. As the baffle plate moves, the deflection angle of the guiding plate becomes larger, and the limiting plate is pushed to slide upward. At this time, the inclination degree of the guiding plate becomes larger, which is beneficial to the discharge of paper scraps.

[0007] Preferably, the top of the guide rail is fixedly connected to the bottom of the crushing shell, the bottom of the crushing shell is fixedly connected to the top of the fixing plate, and one end of the compression spring away from the fixing plate is fixedly connected to the outside of the baffle plate. The baffle plate slides along the guide rail and approaches the fixing plate, and when the compression spring outside the guide rod is compressed by the force during the sliding process, the blanking device can be opened.

[0008] Preferably, the outside of the mounting plate is fixedly connected to the output end of the telescopic cylinder, the outside of the push plate is in contact with the outside of the bearing plate, and the outer wall of the extrusion roller is rollingly connected to the bottom of the inner wall of the processing box. The telescopic cylinder contracts, and at this time, the mounting plate drives the extrusion roller to roll through the assembly frame to extrude and shape the paper scraps falling into the processing box.

[0009] Preferably, a pneumatic push rod is fixedly connected to the inner wall of the assembly frame, the output end of the pneumatic push rod is fixedly connected to a connecting plate, a movable rod is rotatably connected to the top of the connecting plate, an elastic scraper is rotatably connected to the top end of the movable rod, and a scraping plate is fixedly connected to the bottom of the connecting plate. After the extrusion is completed, the telescopic cylinder extends to drive the extrusion device to move, and at the same time, the pneumatic push rod extends. At this time, the scraping plate is separated from the extrusion roller, and the bottom of the elastic scraper comes into contact with the bottom of the processing box again. At this time, the formed paper scraps can be pushed towards the discharge pipe through the elastic scraper.

[0010] Preferably, the bottom of the connecting plate is slidably connected to the inner wall of the assembly frame, both sides of the elastic scraper are rotatably connected to the outside of the assembly frame, and the outer wall of the scraping plate is in contact with the outer wall of the extrusion roller. The pneumatic push rod contracts, so that the connecting plate drives the scraping plate to contact the rotating extrusion roller, and the paper scraps adhered to the extrusion roller can be scraped off in time.

[0011] Preferably, the diffusion assembly includes an annular shell, a flow dividing plate is fixedly connected to the top of the annular shell, a filter plate is fixedly connected to the bottom of the annular shell, a rotating shaft is rotatably connected to the center of the filter plate, a flow disturbing fan is fixedly connected to the outside of the rotating shaft, and a scraping rod is fixedly connected to the bottom end of the rotating shaft. The function of the filter plate is to make the water flow out evenly to realize uniform humidification of the crushed carton.

[0012] Preferably, the top of the flow splitter is fixedly connected to the outer side of the current collector housing, the top of the rotating shaft is rotatably connected to the center of the flow splitter, the outer side of the scraping rod is slidably connected to the outer side of the filter plate, and the turbulence fan is located inside the annular housing. The cleaning effect of the scraping rod can ensure that the filter plate always maintains a good filtering state, thus ensuring the uniformity of the humidifying effect.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. By providing a blanking device in the present invention, during the opening process of the blanking device, as the baffle moves, the deflection angle of the guiding plate becomes larger, and the limiting plate is pushed upward to slide. At this time, the inclination degree of the guiding plate becomes larger, which is beneficial to the discharge of paper scraps, providing a smoother discharge channel for the shredded paper scraps. The larger inclination angle enables the paper scraps to slide down more quickly under the action of gravity, reducing the possibility of accumulation and blockage of the paper scraps at the blanking device.

[0015] 2. By providing a guiding plate in the present invention, during the movement of the guiding plate, the anti-blocking and dredging frame installed above it moves together, and can agitate and dredge the paper scraps while the baffle is opened, ensuring that the paper scraps can smoothly enter the processing box through the blanking device.

[0016] 3. By providing a spraying device in the present invention, the shredded cardboard boxes are uniformly humidified. This helps to increase the flexibility of the cardboard fragments, reduce breakage and flying during subsequent processing, improve the efficiency and quality of recycling, and at the same time, a large amount of dust is generated during the process of shredding cardboard boxes. These dusts not only pollute the environment but also pose a hazard to the health of operators. Spraying and humidifying can make the dust particles adhere to the cardboard fragments, thus effectively suppressing the flying of dust and improving the working environment.

[0017] 4. By providing a diffusion component in the present invention, water flows into the annular housing through the flow splitter and impacts the turbulence fan, causing the turbulence fan to drive the rotating shaft to rotate. At this time, the rotating shaft drives the scraping rod to slide along the surface of the filter plate, preventing paper scraps from adhering to the surface of the filter plate. The cleaning effect of the scraping rod can ensure that the filter plate always maintains a good filtering state, thus ensuring the uniformity of the humidifying effect.

[0018] 5. By providing a telescopic cylinder in the present invention, when the telescopic cylinder contracts, the mounting plate drives the extrusion roller to roll through the assembly frame, and extrudes and shapes the paper scraps falling into the processing box. This process can reduce the volume of the paper scraps, increase their density, and make them more convenient for storage, transportation and subsequent reuse.

[0019] 6. By providing an extrusion device in the present invention, the mounting plate drives the push plate to reset and separate from the surface of the bearing plate. At this time, under the elastic force of the compression spring, the material blocking plate closes again, preventing the paper scraps above from falling into the processing box disorderly during the extrusion process and avoiding interference with the ongoing extrusion and shaping work. This ensures that the extrusion process can be carried out under relatively stable conditions, improving the consistency and reliability of the extrusion effect.

[0020] 7. By providing a scraping plate in the present invention, the pneumatic push rod contracts, causing the connecting plate to drive the scraping plate to contact the rotating extrusion roller, and the paper scraps adhered to the extrusion roller can be scraped off in a timely manner. This avoids the continuous accumulation of paper scraps on the extrusion roller, affecting the normal operation of the extrusion roller and the extrusion effect.

[0021] 8. By providing a connecting plate in the present invention, the connecting plate drives the elastic scraping plate to rotate along the assembly frame through the movable rod, and the bottom of the elastic scraping plate separates from the bottom of the processing box, reducing wear and extending the overall service life of the equipment.

[0022] 9. In the present invention, when the telescopic cylinder extends to drive the extrusion device to move, and at the same time the pneumatic push rod extends, the scraping plate separates from the extrusion roller, and the bottom of the elastic scraping plate contacts the bottom of the processing box again. At this time, the formed paper scraps can be pushed towards the discharge pipe through the elastic scraping plate, ensuring that the paper scraps can be quickly and orderly discharged from the processing box and improving the discharge efficiency.

[0023] 10. By providing a feeding device that cooperates with the extrusion device in the present invention, it is ensured that after the equipment completes one extrusion operation, it can quickly start the next round of processing process, realizing continuous operation and improving production efficiency. The contact between the push plate and the bearing plate, the opening of the feeding device, and the discharging action of the elastic scraping plate cooperate with each other, making the actions of each part of the equipment more coordinated. This synchronous operation ensures the smooth progress of the entire recycling and crushing process, improving the overall performance and reliability of the equipment.

When in use, the packaging carton to be recycled is put into the crushing shell 2 from the feed hopper 9. The outer motor drives the crushing roller 4 inside the crushing shell 2 to rotate, and the carton is crushed. At this time, the blanking device 5 is in a closed state, and the crushed carton fragments are accumulated at the bottom of the crushing shell 2.

[0037] Subsequently, the telescopic cylinder 6 extends, so that the push plate 72 in the extrusion device 7 displaces inside the processing box 1, and at the same time contacts the bearing plate 52 and pushes the bearing plate 52 to drive the baffle plate 51 to displace. At this time, the baffle plate 51 slides along the guide rail 53 and approaches the fixing plate 54, and the compression spring 56 on the outside of the guide rod 55 is compressed under force during the sliding process. Thus, the blanking device 5 can be opened, and the crushed paper scraps fall into the processing box 1.

[0038] The top of the material baffle 51 is rotatably connected to a guiding plate 57. The top of the guiding plate 57 is rotatably connected to a limiting plate 58. The outside of the guiding plate 57 is fixedly connected to an anti-blocking and dredging frame 59. Both sides of the limiting plate 58 are slidably connected to the inner wall of the crushing shell 2. The bottom of the crushing shell 2 is slidably connected to the top of the material baffle 51. The top of the guide rail 53 is fixedly connected to the bottom of the crushing shell 2. The bottom of the crushing shell 2 is fixedly connected to the top of the fixing plate 54. One end of the compression spring 56 away from the fixing plate 54 is fixedly connected to the outside of the material baffle 51. During the opening process of the blanking device 5, as the material baffle 51 moves, the deflection angle of the guiding plate 57 becomes larger, and the limiting plate 58 is pushed to slide upward. At this time, the inclination degree of the guiding plate 57 becomes larger, which is beneficial to the discharge of paper scraps and provides a smoother discharge channel for the crushed paper scraps. The larger inclination angle enables the paper scraps to slide down more quickly under the action of gravity, reducing the possibility of paper scraps piling up and blocking at the blanking device 5. Among them, during the movement of the guiding plate 57, the anti-blocking and dredging frame 59 installed above it moves together, and can stir and dredge the paper scraps while the material baffle 51 is opened, ensuring that the paper scraps can smoothly enter the processing box 1 through the blanking device 5.

[0039] The outer side of the mounting plate 71 is fixedly connected to the output end of the telescopic cylinder 6. The outer side of the push plate 72 is in contact with the outer side of the bearing plate 52. The outer wall of the extrusion roller 74 is rotatably connected to the bottom of the inner wall of the processing box 1. The inner wall of the mounting frame 73 is fixedly connected with a pneumatic push rod 75. The output end of the pneumatic push rod 75 is fixedly connected with a connecting plate 76. The top of the connecting plate 76 is rotatably connected with a movable rod 77. The top end of the movable rod 77 is rotatably connected with an elastic scraper 78. The bottom of the connecting plate 76 is fixedly connected with a scraping plate 79. The bottom of the connecting plate 76 is slidably connected with the inner wall of the mounting frame 73. The two sides of the elastic scraper 78 are rotatably connected with the outer side of the mounting frame 73. The outer wall of the scraping plate 79 is in contact with the outer wall of the extrusion roller 74. Then the telescopic cylinder 6 contracts. At this time, the mounting plate 71 drives the extrusion roller 74 to roll through the mounting frame 73, and extrudes and shapes the paper scraps falling into the processing box 1. This process can reduce the volume of the paper scraps, increase their density, and make them more convenient for storage, transportation and subsequent reuse. During this process, the mounting plate 71 drives the push plate 72 to reset and separate from the surface of the bearing plate 52. At this time, under the elastic force of the compression spring 56, the baffle plate 51 closes again to prevent the paper scraps above from falling into the processing box 1 disorderly during the extrusion process, avoiding interference with the ongoing extrusion and shaping work. Ensure that the extrusion process can be carried out under relatively stable conditions, and improve the consistency and reliability of the extrusion effect. During this process, the pneumatic push rod 75 contracts, so that the connecting plate 76 drives the scraping plate 79 to contact the rotating extrusion roller 74, and can timely scrape off the paper scraps adhered to the extrusion roller 74. Avoid the continuous accumulation of paper scraps on the extrusion roller 74, affecting the normal operation and extrusion effect of the extrusion roller 74. At the same time, the connecting plate 76 drives the elastic scraper 78 to rotate along the mounting frame 73 through the movable rod 77, and makes the bottom of the elastic scraper 78 separate from the bottom of the processing box 1, reducing wear and extending the overall service life of the equipment; after the extrusion is completed, the telescopic cylinder 6 extends to drive the extrusion device 7 to move, and at the same time the pneumatic push rod 75 extends. At this time, the scraping plate 79 separates from the extrusion roller 74, and the bottom of the elastic scraper 78 contacts the bottom of the processing box 1 again. At this time, the formed paper scraps can be pushed towards the discharge pipe 8 through the elastic scraper 78, ensuring that the paper scraps can be quickly and orderly discharged from the processing box 1, improving the discharge efficiency. At the same time, as the push plate 72 contacts the bearing plate 52 again, the blanking device 5 can be restarted, so that after the equipment completes one extrusion operation, it can quickly start the next round of processing process, realizing continuous operation and improving production efficiency. The contact between the push plate 72 and the bearing plate 52 and the opening of the blanking device 5 cooperate with the discharging action of the elastic scraper 78, making the actions of each part of the equipment more coordinated. This synchronous operation ensures the smooth progress of the entire recycling and crushing process, and improves the overall performance and reliability of the equipment.

[0040] The diffusion component 36 includes an annular shell 361. A flow dividing plate 362 is fixedly connected to the top of the annular shell 361. A filter plate 365 is fixedly connected to the bottom of the annular shell 361. A rotating shaft 363 is rotatably connected to the center of the filter plate 365. A turbulence fan 364 is fixedly connected to the outer side of the rotating shaft 363. A scraping rod 366 is fixedly connected to the bottom end of the rotating shaft 363. The top of the flow dividing plate 362 is fixedly connected to the outer side of the confluence shell 35. The top end of the rotating shaft 363 is rotatably connected to the center of the flow dividing plate 362. The outer side of the scraping rod 366 is slidably connected to the outer side of the filter plate 365. The turbulence fan 364 is located inside the annular shell 361. During the process of water flow spraying out through the diffusion component 36, the water flow enters the annular shell 361 through the flow dividing plate 362 and impacts the turbulence fan 364, causing the turbulence fan 364 to drive the rotating shaft 363 to rotate. At this time, the rotating shaft 363 drives the scraping rod 366 to slide along the surface of the filter plate 365, preventing paper scraps from adhering to the surface of the filter plate 365. The function of the filter plate 365 is to make the water flow spray out evenly, realizing uniform humidification of the shredded cartons. If paper scraps adhere to the surface of the filter plate 365, it will destroy the uniform distribution of the water flow, resulting in uneven humidification effect. The cleaning function of the scraping rod 366 can ensure that the filter plate 365 always maintains a good filtering state, thus ensuring the uniformity of the humidification effect.

[0041] Working principle:

[0042] During use, the packaging carton to be recycled is put into the crushing shell 2 from the feeding hopper 9. The outer motor drives the crushing roller 4 inside the crushing shell 2 to rotate, performing crushing treatment on the carton. At this time, the blanking device 5 is in a closed state, and the shredded carton fragments are accumulated at the bottom of the crushing shell 2.

[0043] Subsequently, the telescopic cylinder 6 extends, causing the push plate 72 in the extrusion device 7 to displace inside the processing box 1, and at the same time contacting the bearing plate 52 and pushing the bearing plate 52 to drive the baffle plate 51 to generate displacement. At this time, the baffle plate 51 slides along the guide rail 53 and approaches the fixed plate 54, and during the sliding process, the compression spring 56 outside the guide rod 55 is pushed to be compressed, thereby opening the blanking device 5 and enabling the shredded paper scraps to fall into the processing box 1;

[0044] During the opening process of the blanking device 5, as the baffle plate 51 moves, the deflection angle of the guiding plate 57 becomes larger, and the guiding plate 57 is pushed to slide upward. At this time, the inclination degree of the guiding plate 57 becomes larger, which is beneficial to the discharge of paper scraps, providing a smoother discharge channel for the shredded paper scraps. The larger inclination angle enables the paper scraps to slide down more quickly under the action of gravity, reducing the possibility of paper scraps accumulating and blocking at the blanking device 5;

[0045] Among them, during the movement of the guide plate 57, the anti-blocking and dredging frame 59 installed above it moves together, and can stir and dredge the paper scraps while the baffle plate 51 is opened, ensuring that the paper scraps can smoothly pass through the blanking device 5 and enter the processing box 1.

[0046] When the spraying device 3 is in use, water is added into the water storage tank 31 through the water inlet pipe 32. Then the pressure increasing valve 34 is opened, so that the water flow enters the confluence shell 35 through the connecting pipe 33, and finally sprays outwards through the diffusion assembly 36. This can uniformly humidify the shredded cardboard boxes. This helps to increase the flexibility of the cardboard box fragments, reduce breakage and flying during subsequent processing, and improve the efficiency and quality of recycling.

[0047] At the same time, a large amount of dust is generated during the process of shredding cardboard boxes. These dusts not only pollute the environment, but also pose a hazard to the health of operators. Spraying water for humidification can make the dust particles adhere to the cardboard box fragments, thus effectively suppressing the flying of dust and improving the working environment.

[0048] During the process of the water flow spraying out through the diffusion assembly 36, the water flow enters the annular shell 361 through the shunt plate 362 and impacts the turbulence fan 364, causing the turbulence fan 364 to drive the rotating shaft 363 to rotate. At this time, the rotating shaft 363 drives the scraping rod 366 to slide along the surface of the filter plate 365, preventing paper scraps from adhering to the surface of the filter plate 365;

[0049] The function of the filter plate 365 is to make the water flow spray out evenly, realizing the uniform humidification of the shredded cardboard boxes. If paper scraps adhere to the surface of the filter plate 365, it will destroy the uniform distribution of the water flow, resulting in uneven humidification effect. The cleaning function of the scraping rod 366 can ensure that the filter plate 365 always maintains a good filtering state, thus ensuring the uniformity of the humidification effect.

[0050] Then the telescopic cylinder 6 contracts. At this time, the mounting plate 71 drives the extrusion roller 74 to roll through the assembly frame 73, and extrudes and shapes the paper scraps falling into the processing box 1. This process can reduce the volume of the paper scraps, increase their density, and make them more convenient for storage, transportation and subsequent reuse.

[0051] During this process, the mounting plate 71 drives the push plate 72 to reset and separate from the surface of the bearing plate 52. At this time, under the elastic force of the compression spring 56, the baffle plate 51 closes again, preventing the paper scraps above from falling into the processing box 1 disorderly during the extrusion process, and avoiding interference with the ongoing extrusion and shaping work. Ensure that the extrusion process can be carried out under relatively stable conditions, and improve the consistency and reliability of the extrusion effect.

[0052] During this process, the pneumatic push rod 75 contracts, causing the connecting plate 76 to drive the scraping plate 79 into contact with the rotating extrusion roller 74, so that the paper scraps adhered to the extrusion roller 74 can be scraped off in a timely manner. This avoids the continuous accumulation of paper scraps on the extrusion roller 74, which may affect the normal operation and extrusion effect of the extrusion roller 74.

[0053] Meanwhile, the connecting plate 76 drives the elastic scraping plate 78 to rotate along the assembly frame 73 through the movable rod 77, and separates the bottom of the elastic scraping plate 78 from the bottom of the processing box 1, reducing wear and extending the overall service life of the equipment.

[0054] After the extrusion is completed, the telescopic cylinder 6 extends to drive the extrusion device 7 to move, and at the same time the pneumatic push rod 75 extends. At this time, the scraping plate 79 is separated from the extrusion roller 74, and the bottom of the elastic scraping plate 78 comes into contact with the bottom of the processing box 1 again. At this time, the formed paper scraps can be pushed towards the discharge pipe 8 by the elastic scraping plate 78, ensuring that the paper scraps can be discharged from the processing box 1 quickly and orderly, improving the discharge efficiency.

[0055] Meanwhile, as the push plate 72 comes into contact with the bearing plate 52 again, the blanking device 5 can be restarted, ensuring that after one extrusion operation is completed, the equipment can quickly start the next round of processing process, realizing continuous operation and improving production efficiency. The contact between the push plate 72 and the bearing plate 52 and the opening of the blanking device 5 cooperate with the discharging action of the elastic scraping plate 78, making the actions of each part of the equipment more coordinated. This synchronous operation ensures the smooth progress of the entire recycling and crushing process, improving the overall performance and reliability of the equipment.
