[0032] 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.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1-7 The present invention provides a polymer recycling material processing device, including a shell 2, a feed inlet 21 on one side of the top surface of the shell 2, a cutting component fixedly connected and connected to the feed inlet 21, an auger conveyor 4 fixedly connected and connected to the side of the shell 2 away from the cutting component, a storage tank 5 fixedly connected to the lower part of the side of the shell 2 away from the auger conveyor 4, a crushing box 3 fixedly connected inside the shell 2, the crushing box 3 being located below the cutting component, a linear screen 27 being located below the crushing box 3, a second conveyor belt 26 being located below the linear screen 27, and a first conveyor belt 25 being located on one side above the crushing box 3;

[0035] The cutting assembly includes a feed box 11, one side of which is fixedly connected to and communicates with a cutting box 1, and the bottom of the feed box 11 is connected to the outer shell 2.

[0036] To prevent the heat generated by the recycled polymer material during the crushing process from causing the internal temperature of the crushing chamber 3 to rise, resulting in the melting of some components and causing the crushed materials to stick together and fail to achieve the desired crushing effect, the crushing chamber 3 adopts a low-temperature crusher. During the material crushing process, the cold source of the low-temperature crusher forms a closed-loop circulation system, making full use of energy. At the same time, the temperature can be adjusted according to the embrittlement point temperature of the material during the crushing process, selecting the optimal crushing temperature and reducing energy consumption. The low-temperature crusher effectively avoids the problem of the recycled polymer material generating heat and causing the internal temperature of the crushing chamber 3 to rise, resulting in the melting of some components and causing the crushed materials to stick together and fail to achieve the desired crushing effect.

[0037] This invention enables the initial cutting of polymer recycled materials using a cutting component. The cut polymer recycled materials are then crushed in a crushing box 3. The crushed polymer recycled materials are screened by a linear screen 27. Polymer recycled materials that meet the requirements are transported to a storage tank 5 via a second conveyor belt 26 for collection, while polymer recycled materials that do not meet the requirements are transported by an auger conveyor 4 and then transported to the crushing box 3 via a first conveyor belt 25 for further crushing. This invention can produce uniform particles of the processed polymer recycled materials, effectively improving the recycling efficiency and quality of polymer recycled materials.

[0038] In a further optimized design, the feeding end of the feeding box 11 is arranged in an inverted trapezoidal shape, and the bottom of the feeding box 11 is connected to the feeding port 21 through a solenoid valve 12.

[0039] When the polymer recycled material (e.g., EVA or rubber) enters the feed box 11, the solenoid valve 12 is closed to ensure that the polymer recycled material in the feed box 11 is effectively contained within the feed box 11.

[0040] In a further optimized design, the top and bottom surfaces of the cutting box 1 are respectively provided with sliding grooves 13. A lead screw 14 is rotatably connected in the sliding groove 13. One end of the lead screw 14 extending out of the cutting box 1 is connected to a motor 17. The motor 17 is fixedly connected to the outer wall of the cutting box 1. A slider 15 is threadedly connected to the lead screw 14. The slider 15 is slidably connected to the sliding groove 13. Several blades 16 are fixedly connected between two sliders 15. The blades 16 are slidably connected to a through groove 18. The through groove 18 is opened in the cutting box 1 and communicates with the feed box 11.

[0041] The motor 17 drives the lead screw 14 to rotate, so that the lead screw 14 can drive the slider 15 to move along the slide groove 13. The two sliders 15 set up one above the other can drive several blades 16 to move synchronously.

[0042] The design was further optimized by setting several blades 16 at equal intervals, with the through slots 18 corresponding to the blades 16 one by one.

[0043] The motor 17 drives the lead screw 14 to rotate, which in turn drives the slider 15 to move along the chute 13 toward the feed box 11. When the slider 15 drives the blades 16 to extend from the through groove 18 and into the feed box 11, the polymer recycled material can be initially cut by the blades 16, dividing it into several strips. After cutting, the motor 17 reverses, causing the blades 16 to retract into the through groove 18. The separation between the two through grooves 18 prevents the cut polymer recycled material from adhering to the blades 16. At this time, the solenoid valve 12 is opened. After the blades 16 are completely retracted into the through groove 18, the cut polymer recycled material can enter the crushing box 3 through the solenoid valve 12.

[0044] In order to enable the slider 15 to stably drive the blade 16 to move, the blade 16 is T-shaped and is configured such that the two ends of the blade 16 are fixedly connected to the slider 15, so that the blade 16 can move effectively in the through groove 18.

[0045] Further optimization of the scheme: the feed end of the crushing box 3 is fixedly connected to and connected to the discharge end of the feed hopper 31, the feed end of the feed hopper 31 is connected to the feed inlet 21, and the discharge end of the crushing box 3 is fixedly connected to and connected to the discharge pipe 32, which is located above the feed end of the linear screen 27.

[0046] The cut polymer recycled material is sequentially fed into the feed end of the crushing box 3 through the solenoid valve 12, the feed port 21, and the feed hopper 31. The crushing box 3 can crush the cut polymer recycled material.

[0047] Further optimizing the design, the linear screen 27 is fixedly connected to the bottom of the outer casing 2. The discharge end of the linear screen 27 is lower than the feed end. A second guide plate 24 is installed below the discharge end of the linear screen 27, and one end of the second guide plate 24 extending out of the outer casing 2 is connected to the feed end of the auger conveyor 4. A screen 28 is fixedly connected to the linear screen 27 and is positioned above the second conveyor belt 26.

[0048] The crushed polymer recycled material falls onto the linear screen 27 through the discharge pipe 32. The linear screen 27 vibrates and screens the polymer recycled material that meets the requirements, allowing it to fall onto the second conveyor belt 26 through the screen 28. Larger polymer recycled material particles fall onto the second guide plate 24 along the linear screen 27 and then enter the feed end of the auger conveyor 4.

[0049] In a further optimized design, the discharge end of the auger conveyor 4 is fixedly connected to and connected to a first guide plate 23, and one end of the first guide plate 23 extending into the outer casing 2 is positioned above the first conveyor belt 25.

[0050] The auger conveyor 4 transports large-particle polymer recycled material from a low position to a high position, and the polymer recycled material falls from the discharge end of the auger conveyor 4 onto the first conveyor belt 25 through the first guide plate 23.

[0051] In a further optimized design, the first conveyor belt 25 is fixedly connected to the top surface inside the outer casing 2, and the end of the first conveyor belt 25 away from the first guide plate 23 extends into the feed hopper 31.

[0052] Large-particle polymer recycled material is conveyed to the feed hopper 31 by the first conveyor belt 25, so that the large-particle polymer recycled material enters the crushing box 3 for further crushing.

[0053] In a further optimized design, one end of the second conveyor belt 26 is connected to a discharge port 22, which is located on the outer wall of the outer casing 2 facing the storage tank 5. The second conveyor belt 26 transports the qualified recycled polymer material to the storage tank 5 through the discharge port 22.

[0054] A method for processing recycled polymer materials includes the following steps:

[0055] S1. Place the recycled polymer material into the feed box 11; by closing the solenoid valve 12, the recycled polymer material in the feed box 11 can be effectively placed inside the feed box 11.

[0056] S2. The polymer recycled material in the feed box 11 is cut by the cutting box 1; the lead screw 14 is driven to rotate by the motor 17, so that the lead screw 14 can drive the slider 15 to move along the slide groove 13 towards the feed box 11. When the slider 15 can drive the blade 16 to extend from the through groove 18 and into the feed box 11, the polymer recycled material can be initially cut by several blades 16, so that the polymer recycled material is divided into several strips; after the cutting is completed, the motor 17 is reversed to retract the blade 16 into the through groove 18. The separation between the two through grooves 18 prevents the cut polymer recycled material from adhering to the blade 16. At this time, the solenoid valve 12 is opened. When the blade 16 is completely retracted into the through groove 18, the cut polymer recycled material can enter the feed hopper 31 through the solenoid valve 12.

[0057] S3. The cut polymer recycled material is then crushed through the crushing box 3; the crushing box 3 can crush the cut polymer recycled material.

[0058] S4. The crushed polymer recycled material is screened by a linear screen 27; the crushed polymer recycled material falls onto the linear screen 27 through the discharge pipe 32.

[0059] S5. Qualified polymer recycled materials fall onto the second conveyor belt 26, while large particles of polymer recycled materials enter the auger conveyor 4. Through the vibration screening of the linear screen 27, qualified polymer recycled materials pass through the screen 28 and fall onto the second conveyor belt 26. Large particles of polymer recycled materials fall along the linear screen 27 onto the second guide plate 24 and then enter the feed end of the auger conveyor 4.

[0060] S6. The second conveyor belt 26 transports the qualified polymer recycled material to the storage tank 5; the screw conveyor 4 transports the large-particle polymer recycled material to the first conveyor belt 25, and the first conveyor belt 25 transports the large-particle polymer recycled material to the crushing box 3 for crushing.
