[0002] Thermoplastic elastomers, as polymer materials that combine the properties of rubber and plastics, are widely used in many fields such as automobile manufacturing, electronics, and medical supplies. Vibrating sieves are machines used in conjunction with test sieves for particle size analysis, replacing manual sieving. They mainly include tapping sieves, top-impact vibrating sieves, and standard test sieves.
[0003] In existing vibrating screening equipment, thermoplastic elastomer materials are prone to agglomeration due to their own viscosity or electrostatic effects during the conveying process. After these agglomerated material clumps enter the screen body, they need to spend more time dispersing on the screen surface, which prolongs the screening cycle and easily clogs the screen holes, affecting the screening accuracy and making it difficult to ensure the continuity and stability of material supply. Therefore, a vibrating screen for thermoplastic elastomer processing is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a vibrating screen for thermoplastic elastomer processing, comprising a base 1 and a screen body 2. A conveying assembly is installed on the top of the base 1, and a vibrating assembly is installed in the middle of the base 1. A connecting rod 5 is fixedly connected to the outside of the screen body 2. The conveying assembly includes a housing 3, which is fixedly connected to the top of the base 1. A drive motor 14 is fixedly connected to the outside of the housing 3. A spiral blade 12 is fixedly connected to the output end of the drive motor 14. The spiral blade 12 is rotatably connected inside the housing 3. A guide pipe 13 is fixedly connected to the middle of the housing 3. The drive motor 14 drives the spiral blade 12 to rotate inside the housing 3, which can uniformly convey the material from the feed hopper 4 to the screen body 2 through the guide pipe 13 by spiral pushing. This avoids the accumulation or agglomeration of material during the conveying process, ensuring the stability of material supply during screening. The spiral blade can stir and disperse the material during rotation, so that the material is fully pre-treated before entering the screen body 2, which helps to improve the efficiency and quality of subsequent screening. A lower shell 17 is fixedly connected to the middle of the feed tube 13, and an upper shell 23 is fixedly connected to the top of the lower shell 17. A rotating plate 18 is rotatably connected inside the upper shell 23, and a connecting rod 19 is rotatably connected to the outside of the rotating plate 18. A movable plate 20 is fixedly connected to the end of the connecting rod 19, and the movable plate 20 is rotatably connected to the middle of the feed tube 13. A sliding rod 22 is fixedly connected to the middle of the lower shell 17, and a sliding groove 21 is opened in the middle of the rotating plate 18. The sliding rod 22 is slidably connected to the middle of the sliding groove 21. A cylinder 15 is rotatably connected to the outside of the base 1, and a connecting plate 16 is fixedly connected to the outside of the rotating plate 18. The connecting plate 16 is rotatably connected to the end of the cylinder 15. The cylinder 15 extends and retracts, driving the connecting plate 16, which in turn drives the rotating plate 18 to rotate. The rotating plate 18, through a connecting rod 19, causes the movable plate 20 to rotate in the middle of the guide pipe 13, thereby controlling the opening and closing degree of the guide pipe 13 and adjusting the speed and flow rate of the material entering the screen body 2 from the guide pipe 13. A feed hopper 4 is fixedly connected to the top of the outer shell 3, and a connecting rod 5 is rotatably connected to the outside of the base 1, rotating on the outside of the screen body 2. A lifting ring 24 is fixedly connected to the outside of the screen body 2. A lifting rope 25 is provided in the middle of the lifting ring 24. The lifting rope 25 is fixedly connected to the outside of the base 1. The connection between the lifting ring 24 and the lifting rope 25 allows the screen body 2 to vibrate freely within a certain range, providing the necessary space for the screen body 2 to move. This enables the screen body 2 to transmit vibration to the material more effectively, promoting the dispersion and screening of the material, and helping to improve the efficiency and accuracy of screening.
[0033] Reference Figure 1 and Figure 2The vibration assembly includes a drive motor 6, which is fixedly connected to the outside of the base 1. A pulley 7 is fixedly connected to the output end of the drive motor 6. A synchronous belt 8 is sleeved on the outside of the pulley 7. A connecting rod 9 is fixedly connected to the top of the pulley 7. The top of the connecting rod 9 is fixedly connected to the bottom of the connecting rod 5. When the drive motor 6 drives the pulley 7 to rotate, the synchronous belt 8 sleeved on the outside of the pulley 7 will drive the other pulley 7 to rotate synchronously, thus ensuring the stability and accuracy of the transmission. The rotation of the pulley 7 will then drive the connecting rod 9 to perform eccentric circular motion, causing the screen body 2 to vibrate. The vibration can make the thermoplastic elastomer material jump and roll continuously on the screen plate 11, avoiding material blockage of the screen holes and allowing the material to contact the screen plate 11 more fully, thereby improving screening efficiency and accuracy. The screen body 2 has three screen plates 11 fixedly connected inside, and three discharge ports 10 are set in the middle of the screen body 2. By setting multiple screen plates 11 and discharge ports 10, materials of different particle sizes can be more accurately passed through the corresponding screen plates 11 for grading and screening, separating particles of different particle sizes, so that the particle size distribution of the final product is uniform, and different processing technology or treatment methods are adopted according to different grades, further optimizing the production process and improving production efficiency.
[0034] Working principle: Thermoplastic elastomer material enters the interior of the outer shell 3 from the feed hopper 4. The drive motor 14 drives the spiral blade 12 to rotate. The spiral blade 12 can push the material along the spiral direction, so that the material moves smoothly to the feed pipe 13 and finally falls into the interior of the screen body 2.
[0035] The drive motor 6 is started, which drives one of the pulleys 7 to rotate. This, in turn, drives the other pulley 7 via the synchronous belt 8. The rotation of pulley 7 drives the connecting rod 9 in an eccentric circular motion, causing the screen body 2 to vibrate. The material entering the screen body 2 is then screened by the three screen plates 11 inside the screen body 2 under the action of vibration. Materials of different particle sizes are discharged through different screen plates 11 and the discharge port 10. The cylinder 15 extends and retracts, driving the connecting plate 16, which in turn drives the rotating plate 18 to rotate. The rotating plate 18, via the connecting rod 19, causes the movable plate 20 to rotate in the middle of the guide pipe 13, thereby controlling the opening and closing degree of the guide pipe 13 and adjusting the speed and flow rate of the material entering the screen body 2 from the guide pipe 13. Simultaneously, the sliding rod 22 in the lower shell 17 slides in the groove 21 of the rotating plate 18, providing auxiliary support and guidance to ensure the stability of the rotating plate 18's movement.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
