Description

Technical Field

[0001] This invention relates to the field of packaging cardboard raw material recycling and processing technology, specifically to a packaging cardboard raw material recycling and processing equipment. Background Technology

[0002] Recycling cardboard boxes aims to conserve resources, reduce environmental pollution, and promote a circular economy. By recycling waste cardboard boxes, we can reduce wood, water, and energy consumption, decrease carbon emissions, avoid the ecological pressure of landfills, and promote sustainable development. Process: Sorting and Collection: Waste cardboard boxes are sorted by material and collected through recycling points or door-to-door services. Crushing and Pulping: Packaging cardboard boxes are crushed into small pieces, impurities are removed, and then processed into recycled pulp. Recycling: The pulp is used to produce new cardboard boxes or molded pulp products, such as packaging materials or household goods, achieving resource recycling.

[0003] In this process, after the packaging cartons are crushed, screening equipment is used to remove non-metallic impurities and metal nails used to fix the cartons from the carton fragments, thereby improving the quality of the packaging cartons recycling process.

[0015] The present invention has the following beneficial effects: 1. In this packaging carton raw material recycling and processing equipment, the screening cylinder can be connected to the discharge port of the carton crushing equipment, so that the carton fragments flow into the screening tank of the hollow screening cylinder in a quantitative manner. When the electromagnet adsorption roller is energized, it can generate magnetic force, which can adsorb and separate the metal impurities in the carton fragments. The small non-metallic impurity particles are discharged from the screening tank through the first screening hole on the hollow screening roller and flow into the first collection box for collection. The scraper set in the screening tank can drive the turning rod to move back and forth synchronously. On the one hand, it can break up the carton fragments in the corresponding screening tank to avoid accumulation and improve the adsorption effect of the electromagnet adsorption roller on metal impurities. On the other hand, when the scraper moves, it can scrape off the attached material around the first screening hole, reduce blockage, and improve the filtration effect of small non-metallic impurity particles. When the hollow screening roller rotates inside the screening cylinder, it facilitates the rotation of the second gear on the first gear ring, so that the electromagnet adsorption roller can automatically rotate in the corresponding screening groove, thereby increasing the adsorption area and reducing the dead angle of metal impurity adsorption. At the same time, the corresponding first contact rod intermittently contacts several first arc-shaped contact blocks, causing the scraper to drive the turning rod to move back and forth synchronously, turning over the carton fragments and reducing accumulation. Secondly, it can scrape off impurities around the first screening hole, improving the efficiency of automatic separation of small non-metallic impurity particles from carton fragments.

[0016] 2. In this packaging carton raw material recycling and processing equipment, the carton fragments discharged from the discharge chute can be screened a second time through the vibrating screen plate, so that large non-metallic impurity particles are separated from the carton fragments, thereby improving the quality of carton fragment recycling. When the triangular scraper on the sliding rod moves, it can increase the time that the carton fragments stay on the vibrating screen plate. Secondly, it can clean the impurities in the second screening hole of the vibrating screen plate, improving the impurity separation effect. When the discharge port on the screening cylinder is connected to the screening trough, the electromagnet adsorption roller is released from the adsorption state, and the separated metal impurities are automatically discharged from the discharge port. The strip scraper can press against the rotating electromagnet adsorption roller to scrape off the metal impurities attached to the electromagnet adsorption roller, improving the feeding effect and reducing the attachment, so that the adsorption effect of metal impurities is improved when the electromagnet adsorption roller is energized. Several second arc-shaped contact blocks on the hollow screening roller can contact the first contact frame, so that the sliding rod can be driven to move on the screening frame through the connecting rod. With the cooperation of the second contact frame and the guide rod, the second contact rod is made to contact the strip scraper, so that the strip scraper automatically contacts the electromagnet adsorption roller for feeding.

[0017] 3. In this packaging carton raw material recycling and processing equipment, several striking blocks can strike the inner wall of the hollow screening roller. On the one hand, this can improve the flow effect of metal impurities during material feeding and speed up the feeding efficiency. On the other hand, it can make the residual impurities in the flow channel fall into the first collection box during the material feeding of metal impurities, reduce the amount of residual impurities, improve the flow effect of the first screening hole on the side wall of the screening channel for small non-metallic impurity particles, and reduce the risk of blockage. When the guide rod moves, through the cooperation of the second contact strip, the wave contact frame and the first contact strip, the rotating rod drives the striking blocks to reciprocate on the first collection box, which can achieve the purpose of automatically striking the inner wall of the hollow screening roller.

[0027] 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.

[0028] Example 1, please refer to Figures 1 to 8 A packaging cardboard raw material recycling and processing equipment includes a screening frame 1, a screening cylinder 2 fixed above the screening frame 1, a hollow screening roller 3 rotatably connected to the screening cylinder 2, a plurality of screening grooves 4 and flow grooves 5 respectively opened on the hollow screening roller 3, a plurality of first screening holes 6 opened on the hollow screening roller 3, a rotatable electromagnet adsorption roller 7 provided in the screening groove 4, a movable scraper 8 provided in the screening groove 4, and a plurality of strip scrapers 9 slidably connected to the hollow screening roller 3; The screening cylinder 2 has a discharge trough 10, and below the discharge trough 10 is an inclined vibrating screen plate 12. Several sliding rods 11 are provided on the vibrating screen plate 12, and triangular scrapers 13 are installed on the sliding rods 11.

[0029] A servo motor 14 and a first gear ring 15 are fixed on the screening cylinder 2. A second gear ring 16 is fixed at one end of the hollow screening roller 3. A first gear 17 is fixed on the motor shaft of the servo motor 14. The first gear 17 and the second gear ring 16 mesh with each other. A second gear 18 is fixed at one end of the electromagnet adsorption roller 7. The second gear 18 and the first gear ring 15 mesh with each other.

[0030] One end of the scraper frame 8 is fixed with a first abutting rod 19, which is slidably connected to the hollow screening roller 3. A first spring 20 is connected between the scraper frame 8 and the hollow screening roller 3. Several first arc-shaped abutting blocks 21 are fixed on the circumferential surface of the first toothed ring 15. Several turning rods 25 are fixed on the scraper frame 8.

[0031] A support plate 22 is fixed to one end of the screening cylinder 2. A first collection box 24 is provided inside the hollow screening roller 3. A hollow rod 23 is fixed on the support plate 22. The first collection box 24 is fixedly connected to the hollow rod 23. A discharge port 44 is opened on one side of the screening cylinder 2. A second collection box 45 is fixed on the screening frame 1.

[0032] refer to Figures 1 to 6 When in use, the carton shredder shreds the carton into small pieces, which then flow into the feed inlet of the screening cylinder 2 through the discharge port. The servo motor 14 on the screening cylinder 2 is started, and the motor shaft of the servo motor 14 drives the first gear 17 to rotate. The first gear 17 meshes with the second gear ring 16, which drives the hollow screening roller 3 to rotate inside the screening cylinder 2 so that the carton pieces flow into the screening tank 4 in a measured amount. The electromagnet adsorption roller 7 is in an energized state, and the generated magnetic force adsorbs metal impurities. When the hollow screening roller 3 rotates, the second gear 18 fixed at one end of the electromagnet adsorption roller 7 meshes with the first gear ring 15 on the screening cylinder 2, causing the electromagnet adsorption roller 7 to rotate synchronously in the screening tank 4, which can increase the adsorption area and reduce the adsorption dead angle of metal impurities. Meanwhile, small non-metallic impurity particles fall into the first collection box 24 with the cooperation of the screening tank 4, the flow tank 5 and the first screening hole 6, and are separated from the carton fragments. During the rotation of the hollow screening roller 3, the first contact rod 19 and several first arc-shaped contact blocks 21 on the first toothed ring 15 can be intermittently contacted, causing the scraper 8 and the turning rod 25 to reciprocate in the screening tank 4. The first spring 20 continuously stores and releases its elasticity. On the one hand, it disperses the carton fragments in the corresponding screening tank 4, making them evenly distributed and avoiding accumulation, thereby improving the adsorption effect of the electromagnet adsorption roller 7 on metal impurities. On the other hand, when the scraper 8 moves, it can scrape off the attached material around the first screening hole 6, reduce blockage, and improve the filtration effect on small impurity particles, thereby automatically screening the metal impurities and small non-metallic impurity particles in the carton fragments. When the hollow screening roller 3 rotates to the discharge trough 10, the carton fragments that have been initially screened will automatically fall onto the vibrating screen plate 12 below for secondary screening.

[0033] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 8 A number of second springs 26 are connected between the vibrating screen plate 12 and the screening frame 1, and a vibrating motor 27 is fixed on the vibrating screen plate 12. The screening trough 4 and the flow trough 5 are both connected to the hollow screening roller 3. A number of second screening holes 35 are opened on the vibrating screen plate 12.

[0034] A sliding bracket 28 is fixed on one side of the screening frame 1. A first abutment bracket 29 is slidably connected to the sliding bracket 28. A third spring 30 is connected between the first abutment bracket 29 and the sliding bracket 28. Several second arc-shaped abutment blocks 31 are fixed to one end of the hollow screening roller 3.

[0035] Guide grooves 32 are provided on both sides of the screening frame 1. Several sliding rods 11 are slidably connected to the guide grooves 32, and strip plates 33 are connected between the sliding rods 11. A connecting rod 34 is rotatably connected to one of the sliding rods 11, and one end of the connecting rod 34 is fixedly connected to the first contact frame 29.

[0036] One end of one of the sliding rods 11 touches the second abutment 36, which is slidably connected to the support plate 22. The second abutment 36 abuts the guide rod 38, which is elastically connected to the first collection box 24 via the fourth spring 39. A third abutment 40 is fixed on the guide rod 38.

[0037] The third contact frame 40 is slidably connected to the hollow rod 23. A fifth spring 41 is connected between the strip scraper 9 and the hollow screening roller 3. One end of the strip scraper 9 abuts against the second contact rod 42. The second contact rod 42 is slidably connected to the hollow screening roller 3, and a limit ring 43 is fixed to one end of the second contact rod 42.

[0038] refer to Figures 1 to 7 When the vibration motor 27 is started, the vibrating screen plate 12 vibrates on the screen frame 1 in cooperation with several second springs 26. The diameter of the second screening hole 35 is larger than that of the first screening hole 6, so as to separate large non-metallic impurity particles from the cardboard fragments, thereby improving the quality of cardboard fragment recycling. At the same time, when the hollow screening roller 3 rotates, it can drive several second arc-shaped contact blocks 31 to intermittently contact the first contact frame 29. The first contact frame 29 slides back and forth on the sliding bracket 28. Spring 30 continuously stores and releases its elastic force, so that the first contact frame 29 pulls the sliding rod 11 through the connecting rod 34 to slide within the guide groove 32. With the cooperation of the strip plate 33, several sliding rods 11 facilitate the movement of the triangular scraper 13, increasing the time that cardboard fragments remain on the vibrating screen plate 12 and scraping away impurities around the second screening hole 35 of the vibrating screen plate 12, thus improving the impurity separation effect. When one of the sliding rods 11 moves, it abuts against the lower end of the second contact frame 36, causing the first contact frame 29 to move. The second contact frame 36 slides on the support plate 22, achieving the purpose of contacting the guide rod 38. This causes the guide rod 38 to slide on the hollow rod 23 and the first collection box 24. The fourth spring 39 stores energy. At this time, after the corresponding screening groove 4 on the hollow screening roller 3 has finished discharging, it rotates to the impurity discharge port 44. The electromagnet adsorption roller 7 is de-energized, causing the metal impurities to fall onto the hollow screening roller 3, slide out of the impurity discharge port 44, and flow into the second collection box 45. At the same time, the guide rod 38... The third contact frame 40 is driven to contact the corresponding second contact rod 42, causing the second contact rod 42 to slide on the hollow screening roller 3 and contact one end of the strip scraper 9. This causes the strip scraper 9 to automatically move upward and abut against the electromagnet adsorption roller 7 for feeding. The fifth spring 41 stores force, and when the electromagnet adsorption roller 7 rotates, the metal impurities attached to the strip scraper 9 are scraped off, improving the feeding effect and reducing the amount of attached material. When the electromagnet adsorption roller 7 is energized, the adsorption effect of metal impurities can be improved.

[0039] The limiting ring 43 on the second contact rod 42 prevents the second contact rod 42 from detaching from the hollow screening roller 3, thus affecting the performance.

[0040] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 1 to 8 A rotating rod 46 is rotatably connected to the first collection box 24. Several striking blocks 47 are fixed on the rotating rod 46. A torsion spring 48 is connected between the rotating rod 46 and the first collection box 24. A first abutting strip 49 is fixed to one end of the rotating rod 46. A wave abutting frame 50 is abutted on the first abutting strip 49. The wave abutting frame 50 is slidably connected to the first collection box 24. A second abutting strip 37 is fixed to the end of the guide rod 38.

[0041] refer to Figures 1 to 8 As the hollow screening roller 3 rotates, the angle of the flow channel 5 changes, causing impurities to remain in the flow channel 5, which affects the impurity screening effect of the first screening hole 6. It is necessary to discharge the impurities in the flow channel 5. When the guide rod 38 moves, it drives the second abutment strip 37 to move synchronously and intermittently abut against the wave abutment frame 50, so that the wave abutment frame 50 moves vertically back and forth on the first collection box 24, thereby abutting against the first abutment strip 49. This causes the rotating rod 46 to drive the striking block 47 to deflect back and forth on the first collection box 24. The torsion spring 48 continuously stores and releases its elasticity, causing the striking block 47 to continuously strike the inner wall of the hollow screening roller 3. On the one hand, this can improve the flow effect when metal impurities are discharged and speed up the discharge efficiency. On the other hand, it can make the remaining impurities in the flow channel 5 fall into the first collection box 24 when metal impurities are discharged, reducing the amount of residual impurities, improving the flow effect of the first screening hole 6 on the side wall of the screening channel 4 for small non-metallic impurity particles, and reducing the risk of blockage.

[0043] The above description is only a preferred embodiment of the present invention.
