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 easily degradable, 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 recycled 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 internally provided as a hollow structure, and a sliding 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-adapting 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-adapting waste material characteristic crushing assembly for screening and classifying different types of plastic waste after processing.

[0006] 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.

[0007] 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.

[0008] Furthermore, the adaptive waste material crushing component includes two mirror-shaped movable frames located within a chute.

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.

[0009] 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.

[0012] 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.

[0016] Further, the sieve assembly comprises two No. 1 metal sheets fixedly welded with the bottom of the recycling box, a filter frame is installed between the two No. 1 metal sheets, two No. 2 metal sheets are installed on the side of the filter frame away from the No. 1 metal sheet, the other end of the No. 2 metal sheet is fixedly welded with the bottom of the recycling box, and the length of the No. 1 metal sheet is greater than that of the No. 2 metal sheet.

[0017] Through the above technical scheme, by sorting the plastic waste with large density and flexible plastic waste, different types of plastic waste can be better utilized in the subsequent processing process, the plastic waste is effectively separated, and the risk of excessive wear of the equipment caused by mixed waste is avoided, especially the hard plastic particles are not mixed with flexible plastic after being shaken and screened by the filter frame and the guide frame, which helps to reduce the load that may be generated during the processing of the equipment, thereby prolonging the service life of the equipment.

[0018] Further, the two sides of the end of the guide frame away from the No. 3 metal sheet are provided with No. 4 metal sheets, the other end of the No. 4 metal sheet is fixedly connected with the filter frame, the filter frame and the guide frame are arranged in a V-shaped structure, the length of the No. 3 metal sheet is greater than that of the No. 4 metal sheet, a double-shaft motor is installed on one side of the top of the filter frame, a fixed plate is fixedly connected with the output end of the double-shaft motor, the fixed plate is located outside the recycling box, a connecting rod is rotationally connected with the end of the fixed plate away from the double-shaft motor, and the other end of the connecting rod is rotationally connected with the guide frame.

[0038] As Figures 1-12The adaptive waste characteristic crushing assembly 2 is provided with a screening assembly 3 at the bottom, which is used for screening and classifying different types of plastic waste after treatment. The screening assembly 3 comprises two No. 1 metal sheets 31 welded and fixed to the bottom of the recycling box 11, and a filter frame 39 is installed between the two No. 1 metal sheets 31.

[0039] The working principle of the embodiment is as follows. Before use, the servo motor 27 on the two moving frames 21 drives the adjusting threaded rod 26 to rotate, so that the sliding plate 23 slides transversely on the top of the moving frame 21.

[0040] Then the staff can drive the double threaded rod 12 by rotating the handle 13, so that the two moving frames 21 move oppositely in the chute 14 of the recycling box 11, so that the internal connecting components of the moving frame 21 move oppositely synchronously, and the guide plate 211 on the top of the moving frame 21 moves synchronously with the moving frame 21, while the guide plate 211 rotates relative to the moving frame 21, the support rod 212 rotates relative to the guide plate 211 and the recycling box 11 at both ends, and the plurality of blades 28 on the two moving frames 21 are engaged.

[0041] Then the driving motor 210 drives the driving rod 29 to rotate, which can directly drive the plurality of blades 28 to rotate synchronously under the action of the cross-shaped structure of the driving rod 29, and then the plastic waste can be directly poured from the top of the recycling box 11 into the recycling box 11, and then falls between the two moving frames 21 through the two guide plates 211, and the plastic waste is cut and crushed when passing through the plurality of blades 28.

[0042] The crushed plastic waste directly falls onto the filter frame 39 under the action of gravity, and then the double-shaft motor 35 drives the fixed plate 36 to rotate outside the recycling box 11, so that the connecting rod 37 moves synchronously, and the connecting rod 37 rotates relative to the fixed plate 36, under the action of the third metal sheet 33 and the fourth metal sheet 34, the connecting rod 37 drives the guide frame 38 to vibrate at the other end, and under the action of the first metal sheet 31 and the second metal sheet 32, the filter frame 39 vibrates synchronously, and the crushed plastic waste is screened, the plastic waste particles with higher density fall through the filter holes of the filter frame 39 under the action of gravity and slide onto the guide frame 38 to be collected and arranged, and the crushed flexible plastic waste directly slides out from the other side of the filter frame 39 to be collected and arranged.
