Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of plastic waste recycling, and particularly relates to a plastic waste recycling device. BACKGROUND

[0002] The excessive accumulation of plastic waste has a serious impact on the environment. Plastic is not easy to degrade, and harmful substances are released during its decomposition process, leading to soil, air and water pollution. Recycling plastic waste can reduce the accumulation of these waste and reduce the risk of environmental pollution. Recycling and reusing plastic waste can reduce the demand for new plastic, saving resources and reducing dependence on natural resources such as oil. Recycled plastic can be used to produce new plastic products, improving resource utilization efficiency. Recycling and reusing waste plastic can significantly reduce energy use. For example, the energy consumption of recycling plastic may be only 30% to 50% of that of producing new plastic. Therefore, the plastic waste recycling device can play an important role in energy saving.

[0003] When the existing plastic waste is crushed for recycling, it is often accompanied by flexible solid materials such as rubber, cloth, film, foam and the like, which usually have high elasticity and toughness and are not easy to be cut by blades during crushing. This will cause the equipment to bear a lot of pressure and friction during operation, thereby accelerating the wear and aging of the equipment and shortening the service life of the equipment. Not only does this reduce the crushing efficiency, but it can also cause the processing time to be extended and energy consumption to be increased. In addition, the plastic waste mixed with flexible solid materials after crushing has uneven sizes, and sometimes there are large pieces of material. These large pieces of material are difficult to process subsequently, for example, plastic particles may be mixed with rubber pieces and foam blocks, resulting in inconsistent product quality after recycling and affecting the recycling effect. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a plastic waste recycling device.

[0005] The technical solution adopted to solve the above technical problems is as follows: a plastic waste recycling device, comprising a recycling box body, the recycling box body is hollow inside, and a chute and a through slot are respectively formed through the bottom of the recycling box body on both sides, the recycling box body is internally provided with a self-adaptive waste material characteristic crushing assembly for processing different types of plastic waste and improving recycling efficiency, and a screening assembly is arranged at the bottom of the self-adaptive waste material characteristic crushing assembly for screening and classifying different types of plastic waste after processing. A double-threaded rod is provided on one side of the recycling box, and the double-threaded rod is threadedly connected to the adaptive waste material crushing component. At the same time, a handle is rotatably connected to the recycling box on one side of the double-threaded rod. The handle is rotatably connected to the recycling box, and the through end of the handle is fixedly connected to the double-threaded rod.

[0006] By adjusting the blade spacing, the degree of crushing of waste plastics can be controlled more precisely. Different types of plastics and waste materials may require different degrees of crushing. Different types of plastics can also be processed in a targeted manner, thereby improving the efficiency and effectiveness of recycling. It can efficiently process various waste materials, whether it is film, pipe or hard plastic block, and avoid improper processing caused by differences in the characteristics of waste materials.

[0007] Furthermore, the adaptive waste material crushing component includes two mirror-shaped movable frames located within a chute. The movable frames are slidably connected to a recycling bin, which longitudinally limits the movable frames. A double-threaded rod is threadedly connected to both movable frames. Several linearly equidistant sliding rods are slidably connected inside each movable frame, and the movable frames limit the sliding rods. A blade is rotatably connected to one end of each sliding rod.

[0008] Through the above technical solutions, crushed plastics often need to be classified and sorted. By adjusting the blade spacing, more accurate classification and sorting can be achieved according to the shape and properties of different plastics. Particles of different sizes and shapes are easier to sort automatically in the subsequent process, improving the efficiency and accuracy of sorting.

[0009] Furthermore, several blades are slidably connected to a drive rod, and the drive rod is arranged in a cross shape. The cross end of the drive rod limits the blade longitudinally. Both ends of the drive rod are rotatably connected to the moving frame. A drive motor is installed on the side of the moving frame facing the double threaded rod. The output end of the drive motor is rotatably connected to the moving frame. The through end of the drive motor is fixedly connected to the drive rod.

[0010] Through the above technical solution, the cooperation between the guide plate and the moving frame allows the waste material to smoothly enter the blade area for processing. Through the synchronous movement and rotation of the guide plate, the waste material is evenly distributed between the blades for cutting, which avoids the problem of waste material accumulation or uneven distribution, and helps to maintain cutting efficiency and device stability.

[0011] Furthermore, a sliding plate is slidably connected to the top of the movable frame, and the movable frame limits the sliding plate. At the same time, a fan-shaped groove is opened through the sliding plate. A limiting rod is welded to the top of the side of the slide rod away from the blade, and the limiting rod is located in the fan-shaped groove. The limiting rod is slidably connected to the sliding plate. An adjusting threaded rod is threadedly connected to the side of the sliding plate away from the double threaded rod.

[0012] Through the above technical solution, the blades effectively avoid clogging and uneven processing of waste materials by alternating settings and synchronous rotation during sliding and meshing. The cutting effect is uniform and delicate, which can minimize the amount of large pieces of material in the waste. This is crucial for subsequent recycling and reuse, and it has a significant advantage, especially in the fine processing of materials.

[0013] Furthermore, both ends of the adjusting threaded rod are rotatably connected to the moving frame, and a servo motor is installed on one side of the moving frame. The output end of the servo motor is rotatably connected to the moving frame, and the through end of the servo motor is fixedly connected to the adjusting threaded rod. A guide plate is rotatably connected to the top of the moving frame, and a support rod is rotatably connected to the bottom of the guide plate. At the same time, the other end of the support rod is rotatably connected to the inner wall of the recycling box.

[0014] Through the above technical solution, the relative rotation of the double threaded rod and the guide plate makes the equipment adjustment more flexible. The staff can adjust the equipment according to actual needs to adapt it to plastic waste of different sizes, shapes or hardness, thereby improving the versatility and adaptability of the equipment.

[0015] Furthermore, the screening assembly includes two No. 1 metal plates welded and fixed to the bottom of the recycling box, and a filter frame is installed between the two No. 1 metal plates. At the same time, two No. 2 metal plates are installed on the other side of the filter frame away from the No. 1 metal plates. The other end of the No. 2 metal plates is welded and fixed to the bottom of the recycling box, and the length of the No. 1 metal plate is greater than that of the No. 2 metal plate. No. 3 metal plates are installed on both sides of the filter frame, and a guide frame is installed on the other end of the No. 3 metal plates.

[0016] By using the above technical solution, and separating denser and flexible plastic waste, different types of plastic waste can be better utilized in subsequent processing. The plastic waste is effectively separated, avoiding the risk of excessive wear on the equipment caused by mixed waste. In particular, harder plastic particles will not mix with flexible plastic after being screened by the shaking of the filter frame and the guide frame. This helps to reduce the load that the equipment may generate during the processing, thereby extending the service life of the equipment.

[0017] Furthermore, metal sheets number four are installed on both sides of the guide frame away from the end of metal sheet number three, and the other end of metal sheet number four is fixedly installed to the filter frame. At the same time, the filter frame and the guide frame are arranged in a V-shape. The length of metal sheet number three is greater than that of metal sheet number four. A dual-axis motor is installed on one side of the top of the filter frame, and a fixing plate is fixedly connected to the output end of the dual-axis motor. The fixing plate is located outside the recycling box. A connecting rod is rotatably connected to the end of the fixing plate away from the dual-axis motor, and the other end of the connecting rod is rotatably connected to the guide frame.

[0018] By using the above technical solution, high-density plastic granules and flexible plastic waste can be pre-sorted, which simplifies the subsequent processing. For example, high-density plastic granules can be directly processed into crushing, melting or other recycling processes, while flexible plastics can be processed separately. This reduces the burden on subsequent processing and improves processing efficiency.

[0019] The beneficial effects of the present invention are as follows: (1) The present invention adopts an adaptive waste material crushing component. Through the precise control of two moving frames, the blades can be alternately set and move synchronously in the device, ensuring that each cut can accurately act on the waste. The cooperation between the sliding blades and the guide plate can not only ensure the smooth flow of waste, but also improve the cutting efficiency and uniformity. When plastic waste passes between multiple blades, it will be fully cut and crushed into smaller particles, which is convenient for subsequent processing and recycling. The staff can adjust the equipment according to actual needs to adapt it to plastic waste of different sizes, shapes or hardness, thereby improving the versatility and adaptability of the equipment. (2) By using a screening assembly, the dual-shaft motor drives the fixed plate to rotate outside the recycling box, thereby causing the connecting rod to move synchronously. At the same time, the connecting rod and the fixed plate rotate relative to each other. Under the action of the No. 3 and No. 4 metal plates, the other end of the connecting rod drives the guide frame to shake. Meanwhile, under the action of the No. 1 and No. 2 metal plates, the filter frame shakes synchronously, screening the crushed plastic waste and collecting different types of plastic waste (such as harder and softer plastics) separately. This ensures that each type of plastic material can be recycled and processed separately, avoiding pollution caused by mixing different types of plastics, thereby improving the purity of the recycled materials and the effect of subsequent processing.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] like Figures 1-11As shown in this embodiment, a plastic waste recycling device includes a recycling box 11. The recycling box 11 has a hollow internal structure, and a sliding groove 14 and a through groove 15 are respectively opened through both sides of the bottom of the recycling box 11. A double threaded rod 12 is provided on one side of the recycling box 11. The relative rotation of the double threaded rod 12 and the guide plate 211 makes the adjustment of the equipment more flexible. The operator can adjust the equipment according to actual needs to adapt it to plastic waste of different sizes, shapes or hardness, thereby improving the versatility and adaptability of the equipment. The double threaded rod 12 and the self-adaptive... The waste material crushing component 2 is threadedly connected, and a handle 13 is rotatably connected to the recycling box 11 located on one side of the double threaded rod 12. The handle 13 is rotatably connected to the recycling box 11, and the through end of the handle 13 is fixedly connected to the double threaded rod 12. The recycling box 11 is equipped with the adaptive waste material crushing component 2, which is used to process different types of plastic waste and improve recycling efficiency. The adaptive waste material crushing component 2 includes two mirror-arranged movable frames 21. A sliding plate 23 is slidably connected to the top of the movable frames 21, and the movable frames 21 move relative to the sliding plate 23. The slide plate 23 has a through-hole fan-shaped groove 24. A limit rod 25 is welded to the top of the slide rod 22 on the side away from the blade 28, and the limit rod 25 is located in the fan-shaped groove 24. The limit rod 25 is slidably connected to the slide plate 23. An adjusting threaded rod 26 is threadedly connected to the side of the slide plate 23 away from the double threaded rod 12. The cooperation of the guide plate 211 and the moving frame 21 allows the waste material to smoothly enter the area of ​​the blade 28 for processing. Through the synchronous movement and rotation of the guide plate 211, the waste material is evenly distributed between the blades 28 for cutting, which avoids waste material accumulation or unevenness. The distribution mechanism helps maintain cutting efficiency and device stability. The two ends of the adjusting threaded rod 26 are rotatably connected to the moving frame 21. At the same time, a servo motor 27 is installed on one side of the moving frame 21, and the output end of the servo motor 27 is rotatably connected to the moving frame 21. During the sliding and meshing process, the blade 28 effectively avoids the blockage of waste and uneven processing by alternating and synchronously rotating. The cutting effect is uniform and delicate, which can minimize the amount of large pieces of material in the waste. This is crucial for subsequent recycling and reuse, and has a significant advantage, especially in the fine processing of materials.

[0024] like Figures 2-11 As shown, the servo motor 27 is fixedly connected to the adjusting threaded rod 26 at its through end, and a guide plate 211 is rotatably connected to the top of the moving frame 21, such as... Figure 4It can be seen that at this time, the guide plate 211 is at its maximum tilt angle and is in contact with the recycling box 11. When the two moving frames 21 move in opposite directions, the guide plate 211 and the moving frame 21 rotate relative to each other. At the same time, the guide plate 211 moves synchronously with the moving frame 21, and the support rod 212 at the bottom of the guide plate 211 rotates relative to the guide plate 211 and the moving frame 21, thereby supporting the guide plate 211 in real time. The bottom of the guide plate 211 is rotatably connected to the support rod 212, and the other end of the support rod 212 is connected to the recycling box 11. The inner wall is rotatably connected, and two movable frames 21 are located within the slide groove 14. Simultaneously, the movable frames 21 are slidably connected to the recycling bin 11, which longitudinally limits the movement of the movable frames 21. A double-threaded rod 12 is threadedly connected to both movable frames 21. Several linearly equidistant sliding rods 22 are slidably connected inside the movable frames 21, and the movable frames 21 limit the movement of the sliding rods 22. A blade 28 is rotatably connected to one end of each sliding rod 22. By adjusting the spacing of the blades 28, the degree of crushing of the waste plastic can be more precisely controlled. Different types of plastics and waste may require different degrees of crushing, and different types of plastics can be processed in a targeted manner, thereby improving the efficiency and effect of recycling. It can efficiently process various wastes, whether it is film, pipe or hard plastic block, and can handle them with ease. It avoids improper processing caused by the difference in the characteristics of waste. Several blades 28 are slidably connected to the drive rod 29. The crushed plastic often needs to be classified and sorted. By adjusting the spacing of the blades 28, more accurate classification and sorting can be achieved according to the shape and properties of different plastics. Particles of different sizes and shapes are easier to sort automatically in the subsequent process, improving the efficiency and accuracy of sorting. The drive rod 29 is set in a cross shape. At the same time, the cross end of the drive rod 29 longitudinally limits the blades 28. The two ends of the drive rod 29 are rotatably connected to the moving frame 21. The moving frame 21 is equipped with a drive motor 210 on the side facing the double threaded rod 12. The output end of the drive motor 210 is rotatably connected to the moving frame 21, and the through end of the drive motor 210 is connected and fixed to the drive rod 29.

[0025] like Figures 1-12As shown, the adaptive waste material crushing component 2 is equipped with a screening component 3 at its bottom for screening and classifying different types of processed plastic waste. The screening component 3 includes two primary metal plates 31 welded and fixed to the bottom of the recycling box 11, and a filter frame 39 is installed between the two primary metal plates 31. At the same time, two secondary metal plates 32 are installed on the other side of the filter frame 39 away from the primary metal plates 31. The other end of the secondary metal plates 32 is welded and fixed to the bottom of the recycling box 11, and the length of the primary metal plates 31 is greater than that of the secondary metal plates 31. Metal sheet 32 ​​(number two) and filter frame 39 are mounted on both sides of filter frame 39. A guide frame 38 is mounted on the other end of metal sheet 33. Metal sheets 34 (number four) are mounted on both sides of the guide frame 38 away from metal sheet 33, and the other end of metal sheet 34 is fixedly attached to filter frame 39. By separating denser plastic waste and flexible plastic waste, different types of plastic waste can be better utilized in subsequent processing. The plastic waste is effectively separated, avoiding the impact of mixed waste on the equipment. This reduces the risk of excessive wear, especially since harder plastic particles, after being shaken and screened by the filter frame 39 and guide frame 38, will not mix with flexible plastics. This helps reduce the load that the equipment may generate during processing, thereby extending the service life of the equipment. At the same time, the filter frame 39 and guide frame 38 are arranged in a V-shape. The length of the No. 3 metal sheet 33 is greater than that of the No. 4 metal sheet 34. A dual-axis motor 35 is installed on one side of the top of the filter frame 39, and the output end of the dual-axis motor 35 is fixedly connected to a fixing plate 36. The fixing plate 36 is located outside the recycling box 11. The end of the fixing plate 36 away from the dual-axis motor 35 is rotatably connected to a connecting rod 37, and the other end of the connecting rod 37 is rotatably connected to the guide frame 38. The pre-sorting of higher density plastic particles and flexible plastic waste simplifies the subsequent processing flow. For example, higher density plastic particles can directly enter crushing, melting or other recycling processes, while flexible plastics can be processed separately. In this way, the burden in the subsequent processing is reduced and the processing efficiency is improved.

[0026] The working principle of this embodiment is as follows: Before use, the servo motors 27 on the two moving frames 21 drive the adjusting threaded rods 26 to rotate, so that the slide plate 23 slides laterally on the top of the moving frame 21. During the sliding process, the limiting rod 25 on one side of the top of the slide rod 22 slides in the fan-shaped groove 24 of the slide plate 23, thereby causing several slide rods 22 to slide to both sides of the moving frame 21 with the center line of the moving frame 21 as the dividing line, thereby synchronously driving the blades 28 to slide on the drive rod 29, causing several blades 28 on one side of the two moving frames 21 to be alternately set.

[0027] Then, the operator can rotate the handle 13 to drive the double threaded rod 12 to rotate, so that the two moving frames 21 move in opposite directions in the slide groove 14 of the recycling box 11, so that the internal connecting components of the moving frames 21 move in opposite directions synchronously. In addition, the guide plate 211 on the top of the moving frame 21 moves synchronously with the moving frame 21, and the guide plate 211 rotates relative to it. The two ends of the support rod 212 rotate relative to the guide plate 211 and the recycling box 11 respectively, causing the several blades 28 on the two moving frames 21 to mesh.

[0028] Then, the drive motor 210 runs and drives the drive rod 29 to rotate. Under the action of the cross-shaped structure of the drive rod 29, it can directly drive several blades 28 to rotate synchronously. Then, the plastic waste can be poured directly from the top of the recycling box 11 into the inside of the recycling box 11, and then slide down between the two moving frames 21 through the two guide plates 211. When the plastic waste passes between the several blades 28, it is cut and crushed.

[0029] The crushed plastic waste falls directly onto the filter frame 39 under the influence of gravity. Then, the dual-shaft motor 35 drives the fixed plate 36 to rotate outside the recycling box 11, which causes the connecting rod 37 to move synchronously. At the same time, the connecting rod 37 and the fixed plate 36 rotate relative to each other. Under the action of the third metal plate 33 and the fourth metal plate 34, the other end of the connecting rod 37 drives the guide frame 38 to shake. Simultaneously, under the action of the first metal plate 31 and the second metal plate 32, the filter frame 39 shakes synchronously, screening the crushed plastic waste. The denser plastic waste particles fall through the filter holes of the filter frame 39 under the influence of gravity and slide out onto the guide frame 38 for collection and sorting. The crushed flexible plastic waste slides out directly from the other side of the filter frame 39 for collection and sorting.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
