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.
[0027] The following describes an embodiment of this utility model based on its overall structure.
[0028] like Figures 1 to 4 As shown, this utility model provides a plastic float density sorting device, including a sorting device body 1. A connecting pipe 9 is fixedly provided on the top of the sorting device body 1. An electric slide rail 22 is fixedly provided inside the connecting pipe 9. A slider 23 is slidably provided inside the electric slide rail 22. An adjusting plate 19 is fixedly provided on the right side of the slider 23. A hydraulic telescopic column 25 is fixedly provided on the rear side of the adjusting plate 19. An adjusting groove 24 is provided on the front side of the adjusting plate 19. The electric slide rail 22 is provided. By sliding the slider 23 in the electric slide rail 22, the hydraulic telescopic column 25 is extended and retracted, thereby causing the adjusting plate 19 to extend and retract, thereby adjusting the gap between the adjusting plate 19 and the adjusting plate 20, so that plastic floats of a certain size can pass through.
[0029] In this embodiment, a hydraulic telescopic rod 21 is fixedly installed inside the connecting pipe 9. An adjusting plate 20 is fixedly installed on the left side of the hydraulic telescopic rod 21. An adjusting groove 24 is opened on the left side of the adjusting plate 20. The hydraulic telescopic rod 21 is installed so that the position of the adjusting plate 20 can be adjusted by extending and retracting the hydraulic telescopic rod 21, thereby adjusting the size of the gap formed by the adjusting plate 20 and the adjusting plate 19. This allows for adjustment according to the size of the plastic float, making the sorting more accurate and preventing the size of the plastic float from affecting the sorting. A trapezoidal block 4 is fixedly installed above the connecting pipe 9. A vibrating plate 7 is fixedly installed inside the trapezoidal block 4. A vibrating plate 7 is fixedly installed above the vibrating plate 7. A guide plate 6 is fixedly provided, and a second motor 8 is fixedly provided on the outside of the guide plate 6. A feed inlet 5 is opened inside the trapezoidal block 4, and the second motor 8 is installed there. By starting the second motor 8, the vibration is transmitted through the guide plate 6 to the vibrating plate 7. During material feeding, the vibration prevents the plastic float ball from blocking the feed inlet 5. A rotating shaft 12 is fixedly provided inside the sorting device body 1. A stirring frame 11 is rotatably provided on the right side of the rotating shaft 12. A first motor 3 is fixedly provided on the right side of the stirring frame 11. A water outlet 13 is opened on the left side of the sorting device body 1, and a first motor 3 is installed there. By adding cleaning liquid into the sorting device body 1 and starting the first motor 3, the second stirring frame 11 is activated. 1. The device rotates together with the rotating shaft 12 to clean the plastic float, removing impurities and oil from its surface to prevent them from affecting the sorting process. After cleaning, the cleaning liquid flows out through the outlet 13. A fixing plate 15 is fixedly installed inside the sorting device body 1. A second fixing plate 16 is slidably installed inside the fixing plate 15. Slider blocks 18 are fixed on both the front and rear sides of the second fixing plate 16. An electric slide rail 17 is fitted to the outside of the slider 18 and is fixedly installed to the sorting device body 1. After the cleaning liquid flows out, the electric slide rail 17 is set up, and the slider 18 moves along the electric slide rail. The plastic floats slide in the first track 17, causing the second fixed plate 16 to slide in the first fixed plate 15, thus separating the first fixed plate 15 and allowing the plastic float to enter the next chamber for sorting. The main body 1 of the sorting device is equipped with a second rotating shaft 14. A stirring frame 10 is rotatably mounted on the right side of the second rotating shaft 14. A motor 3 is fixed on the right side of the stirring frame 10. A sorting groove 2 is opened on the top of the main body 1 of the sorting device, and a motor 3 is installed there. By starting the motor 3, the stirring frame 10 rotates together with the second rotating shaft 14, causing the liquid medium inside to generate a uniform and appropriate flow, avoiding local eddies and dead zones, and allowing the plastic float to be fully dispersed in the medium, thereby improving the sorting accuracy.
[0030] Working principle and process of a plastic float density sorting device:
[0031] In use, a plastic float density sorting device works by sliding a slider 23 within an electric slide rail 22, causing the hydraulic telescopic column 25 to extend and retract, which in turn causes the adjusting plate 19 to extend and retract. The position of the adjusting plate 20 is adjusted by the extension and retraction of the hydraulic telescopic rod 21, thereby adjusting the size of the gap between the adjusting plate 20 and the adjusting plate 19. This allows for adjustment based on the size of the plastic float. After adjustment, the plastic float enters through the feed inlet 5 and falls into the sorting device body 1 through the gap between the adjusting plate 19 and the adjusting plate 20. Simultaneously, the motor 28 is activated, causing vibration to be transmitted through the guide plate 6 to the vibrating plate 7. During feeding, the vibration prevents the plastic float from blocking the feed inlet 5. After the plastic float enters the sorting device body 1, it is further adjusted by adding [something] into the sorting device body 1. The cleaning liquid is used to clean the plastic floats by starting motor 3, which causes the stirring rack 11 to rotate with the rotating shaft 12. This cleans the plastic floats, removing impurities and oil from their surfaces and preventing them from affecting the sorting process. After cleaning, the cleaning liquid flows out through outlet 13. After the cleaning liquid flows out, an electric slide rail 17 is set up, and the slider 18 slides in the electric slide rail 17, causing the fixing plate 16 to slide in the fixing plate 15. This causes the fixing plate 15 to separate, allowing the plastic floats to enter the next chamber for sorting. After the floats fall, starting motor 3 causes the stirring rack 10 to rotate with the rotating shaft 14, creating a uniform and appropriate flow of the liquid medium. This avoids local eddies and dead zones, allowing the plastic floats to be fully dispersed in the medium and improving sorting accuracy.
