Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyurethane elastomer recycling technology, and in particular to a thermoplastic polyurethane elastomer recycling device. Background Technology
[0002] Thermoplastic polyurethane elastomers have the elasticity of rubber and the properties of plastic at room temperature, and melt into a viscous fluid at high temperatures. They can be processed by injection molding machines (such as extrusion, injection, calendering, blow molding, compression molding, etc.) without the need for post-processing processes such as mixing and vulcanization, and the products can be recycled and reused.
[0003] The recycling process for thermoplastic polyurethane elastomers involves crushing, washing, and melting. In existing technologies, after washing the thermoplastic polyurethane elastomers, a significant amount of water stains remain on the surface, resulting in low efficiency for manual removal and increased workload. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where a significant amount of water stains remain on the surface of thermoplastic polyurethane elastomers, resulting in low efficiency and increased workload for manual removal. Therefore, this invention proposes a thermoplastic polyurethane elastomer recycling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A thermoplastic polyurethane elastomer recycling device includes a U-shaped frame;
[0007] The top of the U-shaped frame is fixed with a U-shaped frame, and the upper side of the U-shaped frame is provided with a material box for accommodating polyurethane elastomer. The material box includes a box body and a gap bottom plate. The box body slides on the top of the U-shaped frame, and the gap bottom plate rotates on the bottom of the box body. A set of connecting components is provided between the gap bottom plate and the box body.
[0008] A tumbling assembly, located at the side end of a U-shaped frame, is used to tumble and flip the polyurethane elastomer inside the material box.
[0009] A stirring assembly, located inside the housing, is used to continuously tumble the polyurethane elastomer.
[0010] Two support columns are fixed at the top of the U-shaped frame, and a connecting pipe is fixed inside the two support columns. Multiple cleaning nozzles are fixedly connected to the surface of the connecting pipe. The multiple cleaning nozzles are used to clean the polyurethane elastomer. A water inlet pipe is fixed to the side end of the connecting pipe, and the water inlet pipe is connected to the outlet of the water pump.
[0011] In one possible design, the turbulence assembly includes a fixed plate fixed to the side end of the U-shaped frame. Two connecting rods are fixed to the side end of the box body. The side ends of the two connecting rods move outward through the U-shaped frame and are fixed to the same adjusting plate. A sliding groove is provided in the adjusting plate, and a slider slides in the sliding groove. A rotating rod is rotated at the top of the fixed plate, and the slider is fixed to the top of the rotating rod. A drive motor is fixed at the bottom end of the fixed plate, and the drive motor is fixedly connected to the rotating rod through a coupling.
[0012] In one possible design, the stirring assembly includes two rotating shafts that rotate within a U-shaped frame. The housing has two grooves, and the two rotating shafts are movably disposed within the two grooves. Multiple stirring rods are fixed to the surfaces of the two rotating shafts.
[0013] In one possible design, the stirring assembly further includes two drive gears, which are respectively fixed to the surfaces of two rotating shafts. A drive rack is fixed to the side end of the housing, and the drive rack meshes with the two drive gears respectively.
[0014] In one possible design, the connecting assembly includes a connecting plate fixed to the side end of the gap base plate, the connecting plate having a matching groove, the box having a threaded groove that matches the matching groove, a bolt being threadedly connected to the threaded groove, and the bolt being located in the matching groove.
[0015] In one possible design, a water tank for recycling wastewater is placed inside the U-shaped frame.
[0016] In this application, during use, the crushed polyurethane elastomer is poured into the box and the gap bottom plate. The drive motor is started to drive the rotating rod to rotate, and the rotating rod drives the slider to move in a circular motion. When the slider moves in a circular motion, it slides in the sliding groove. The slider drives the adjusting plate to move in a reciprocating linear motion. The adjusting plate drives the two connecting rods to move in a reciprocating linear motion. The connecting rods drive the box to move in a reciprocating linear motion on the U-shaped frame, thereby agitating the polyurethane elastomer in the box. The water pump is started to pump water into the connecting pipe, and then through the connecting pipe to multiple cleaning nozzles. The multiple cleaning nozzles can effectively clean the agitated polyurethane elastomer.
[0017] When the box moves back and forth, it drives the drive rack to move back and forth as well. The movement of the drive rack drives two drive gears to rotate, which in turn drives two rotating shafts to rotate. These shafts then drive multiple stirring rods to rotate, stirring and tumbling the polyurethane elastomer for a more thorough cleaning.
[0018] Beneficial effects: In this utility model, the thermoplastic polyurethane elastomer recycling device, by setting up a tumbling component and a stirring component, can tumble and continuously stir the polyurethane elastomer in the material box, thereby improving the recycling efficiency and quality.
[0019] In this invention, by setting up a cleaning nozzle and a connecting pipe, polyurethane elastomers can be cleaned, removing dirt and impurities from their surface, thereby improving the purity and utilization rate of recycled materials.
[0020] In this invention, after the water pump is turned off, the polyurethane elastomer can continue to be shaken and turned over, which can effectively remove water stains from the surface of the polyurethane elastomer. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1: Refer to Figures 1-4A recycling device includes a U-shaped frame 1, with a U-shaped frame 2 fixed to the top of the U-shaped frame 1. A material box for accommodating polyurethane elastomer is provided on the upper side of the U-shaped frame 2. The material box includes a box body 6 and a hollow bottom plate 7. The box body 6 slides on the top of the U-shaped frame 2, and the hollow bottom plate 7 rotates on the bottom of the box body 6. A set of connecting components is provided between the hollow bottom plate 7 and the box body 6.
[0028] A tumbling assembly is located at the side end of the U-shaped frame 2 to tumble and flip the polyurethane elastomer inside the material box. The tumbling assembly includes a fixed plate 17 fixed to the side end of the U-shaped frame 2, and two connecting rods 18 fixed to the side end of the box body 6. The side ends of the two connecting rods 18 extend outward through the U-shaped frame 2 and are fixed with the same adjusting plate 19. A sliding groove 20 is provided in the adjusting plate 19, and a slider 21 slides in the sliding groove 20. A rotating rod 22 rotates at the top end of the fixed plate 17, and the slider 21 is fixed to the top end of the rotating rod 22. A drive motor 23 is fixed to the bottom end of the fixed plate 17, and the drive motor 23 is fixedly connected to the rotating rod 22 through a coupling. When the drive motor 23 starts, it can drive the rotating rod 22 to rotate. The rotation of the rotating rod 22 causes the slider 21 to slide in the sliding groove 20. The sliding of the slider 21 causes the adjusting plate 19 to move up and down. The up and down movement of the adjusting plate 19 causes the box 6 to bounce on the U-shaped frame 2 through the connecting rod 18, thereby causing the polyurethane elastomer in the box to bounce and flip.
[0029] A stirring assembly is housed within the housing 6 for continuously tumbling the polyurethane elastomer. The stirring assembly includes two rotating shafts 12 that rotatably within the U-shaped frame 2. Two grooves 16 are formed within the housing 6, and the two rotating shafts 12 are movably positioned within these grooves. Multiple stirring rods 13 are fixed to the surfaces of each rotating shaft 12. The stirring assembly also includes two drive gears 14, which are respectively fixed to the surfaces of the two rotating shafts 12. A drive rack 15 is fixed to the side end of the housing 6, meshing with each of the two drive gears 14. When the housing 6 oscillates on the U-shaped frame 2, the drive rack 15 moves accordingly. This movement of the drive rack 15 drives the two drive gears 14 to rotate, which in turn causes the two rotating shafts 12 to rotate within the grooves 16. The rotation of the two rotating shafts 12 then drives the multiple stirring rods 13 to continuously tumble the polyurethane elastomer.
[0030] Two support columns 3 are fixed to the top of the U-shaped frame 2. A connecting pipe 4 is fixed inside each support column 3. Multiple cleaning nozzles 5 are fixedly connected to the surface of the connecting pipe 4, and all cleaning nozzles 5 are used to clean the polyurethane elastomer. A water inlet pipe is fixed to the side end of the connecting pipe 4, and the water inlet pipe is connected to the outlet of a water pump. When cleaning of the polyurethane elastomer is required, the water pump is started, and the water pump sends clean water into the connecting pipe 4 through the water inlet pipe. The clean water is then sprayed out through the multiple cleaning nozzles 5 to clean the polyurethane elastomer.
[0031] Example 2: Reference Figures 1-4 An improvement on Example 1: A thermoplastic polyurethane elastomer recycling device, applied in the field of polyurethane elastomer recycling technology, includes a connecting assembly comprising a connecting plate 8 fixed to the side of a void base plate 7. A matching groove 9 is formed in the connecting plate 8, and a threaded groove 10 matching the matching groove 9 is formed in the box body 6. A bolt 11 is threaded into the threaded groove 10, and the bolt 11 is located within the matching groove 9. When it is necessary to connect the void base plate 7 and the box body 6, the matching groove 9 on the connecting plate 8 and the threaded groove 10 on the box body 6 are aligned, and then the bolt 11 is screwed into the threaded groove 10 and tightened, thereby fixing the void base plate 7 and the box body 6 together. When it is necessary to disassemble the void base plate 7, simply unscrew the bolt 11 from the threaded groove 10.
[0032] The U-shaped frame 1 contains a water tank 24 for recycling wastewater.
[0033] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 23 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
