Description
Technical Field
[0001] This utility model relates to the field of vibrating screens, and in particular to a novel multi-layer rotary vibrating screen fixing structure. Background Technology
[0002] A vibrating screen is a highly efficient screening device that primarily uses rotational vibration to screen materials. Its working principle utilizes the centrifugal force generated by an eccentric vibrator to cause the material to diffuse and be screened outwards on the screen surface. Multi-layer vibrating screens typically have multiple screen layers, each capable of screening materials of different particle sizes. This design allows for the simultaneous screening of multiple material sizes, improving work efficiency and grading accuracy.
[0003] A typical vibrating screen consists of a screen body that houses the screen mesh and material, providing a screening area. Bolts are used to fix the edges of screen meshes of different aperture sizes to the screen frame, and nuts are tightened to ensure the screen mesh doesn't easily loosen. A vibrating motor provides the vibration power, causing the material to be screened. However, when the screen mesh becomes clogged or even damaged after prolonged use, replacement is cumbersome due to the complicated installation process and the need for specialized tools. Therefore, a novel multi-layer vibrating screen fixing structure is proposed to solve these problems. Utility Model Content

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, by pressing the connecting rod, the connecting plate rotates, pushing the locking pin to slide on the side wall of the sliding rod. The first spring contracts, causing the locking pin to release its fixation on the screen. This solves the problem of cumbersome installation process and the need for professional installation tools, which leads to complicated replacement. The above technical solution improves the convenience of screen installation and replacement.

[0030] 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.
[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a novel multi-layer vibrating screen fixing structure, including a screen frame 4, a dust cover 5 on the upper surface of the screen frame 4 to prevent dust from flying during screening, an inlet pipe 6 fixedly connected to the side wall of the dust cover 5 for conveying raw materials, an outlet pipe 7 fixedly connected to the side wall of the screen frame 4 for discharging the screened raw materials, a vibration component on the lower surface of the screen frame 4 for moving the material, a primary screen 8 and a secondary screen 9 inside the screen frame 4 for screening the raw materials, a handle 10 fixedly connected to the upper surface of both the primary screen 8 and the secondary screen 9, and a fixing frame 11 fixedly connected to the upper surface of both the primary screen 8 and the secondary screen 9, with a locking post 12 slidably connected inside the fixing frame 11. A sliding rod 13 is connected to the screen frame 4. A first spring 14 is sleeved on the side wall of the sliding rod 13. The first spring 14 is used for rebound and reset. One end of the first spring 14 is fixedly connected to the side wall of the locking post 12. The locking post 12 is used to fix the screen. The other end of the first spring 14 is fixedly connected to the inside of the fixing frame 11. A fixing frame 15 is fixedly connected to the side wall of the locking post 12. A connecting plate 16 is rotatably connected to the side wall of the fixing frame 15. The connecting plate 16 is used to drive the locking post 12 to move. A connecting rod 17 is slidably connected inside the fixing frame 11. The side wall of the connecting plate 16 is rotatably connected to the side wall of the connecting rod 17. The vibration assembly includes a base frame 1, a vibration motor 2, and a damping spring 3. The side wall of the base frame 1 is fixedly connected to the side wall of the vibration motor 2. The output end of the vibration motor 2 is connected to the screen frame 4. One end of the damping spring 3 is fixedly connected to the upper surface of the base frame 1. The other end of the damping spring 3 is fixedly connected to the lower surface of the screen frame 4.
[0032] When using this equipment, first start the vibration motor 2 to generate vibration, which is transmitted to the screen frame 4, and then through the screen frame 4 to the primary screen 8 and the secondary screen 9. The material to be screened is fed into the feed pipe 6. The material falls onto the primary screen 8 and is vibrated for screening. The screened material falls onto the secondary screen 9, and the screened material continues to be vibrated and discharged through the discharge pipe 7. After prolonged use, the screens may become clogged and need to be disassembled and cleaned. Pressing the connecting rod 17 causes the connecting plate 16 to rotate. As the connecting rod 17 continues to move, the connecting plate 16 pushes the fixing frame 15, thereby causing the clamping column 12 to move. During the movement, the clamping column 12 will... Sliding along the side wall of the slide bar 13, as the locking post 12 moves, the first spring 14 is compressed and contracts, causing the locking post 12 to release its fixed position on the screen. It can then be removed for cleaning. After cleaning, the connecting rod 17 needs to be pressed again to move the locking post 12, causing the first spring 14 to contract and align the locking post 12 with the recessed hole inside the screen frame 4. Then, the connecting rod 17 is released, at which point the first spring 14 loses its compression and rebounds. Finally, the locking post 12 is re-locked into the screen frame 4, thus fixing the screen again. This allows the primary screen 8 and the secondary screen 9 to return to their original fixed state and be put back into use.
[0033] Reference Figure 2 and Figure 4 A fixing ring 18 is fixed to the side wall of the screen frame 4. The fixing ring 18 is used to connect the upper and lower screen frames 4. A fixing block 19 is fixedly connected to the side wall of the fixing ring 18. The fixing block 19 is used to lock the retaining ring 21. A connecting frame 20 is provided on the side wall of the fixing ring 18. The retaining ring 21 is slidably connected inside the connecting frame 20. The retaining ring 21 is used to fix the upper and lower fixing rings 18. The side wall of the retaining ring 21 is slidably connected to the side wall of the fixing block 19. A sliding plate 22 is fixedly connected to the side wall of the retaining ring 21. A second spring 23 is sleeved on the side wall of the retaining ring 21. One end of the second spring 23 is fixedly connected to the inside of the connecting frame 20. The other end of the second spring 23 is fixedly connected to the side wall of the sliding plate 22. A vertical groove 24 is opened inside the connecting frame 20. The side wall of the sliding plate 22 is slidably connected to the inside of the vertical groove 24. A connecting block 25 is fixedly connected to the side wall of the fixing ring 18. A rotating plate 26 is rotatably connected inside the connecting block 25. The side wall of the connecting frame 20 is rotatably connected to the side wall of the rotating plate 26. The rotating plate 26 is used to drive the connecting frame 20 to move.
[0034] When the screen frame 4 is fixedly connected, the rotating plate 26 needs to be pulled up so that one end of it rotates inside the connecting block 25, driving the connecting frame 20 to move. When the retaining ring 21 is aligned with the fixing block 19 and in the correct position, the rotating plate 26 needs to be pulled down so that the retaining ring 21 can be smoothly locked inside the fixing block 19. Due to the fixing of the retaining ring 21, the connecting frame 20 will squeeze the second spring 23, while the sliding plate 22 slides inside the vertical groove 24, so that the second spring 23 is under pressure and begins to contract. This process completes the fixing of the upper and lower fixing rings 18, ensuring that they will not loosen or fall off, making it easy to clean or maintain.
[0035] Working principle: When the screen is clogged, pressing the connecting rod 17 causes the connecting plate 16 to rotate. As the connecting rod 17 moves, the connecting plate 16 pushes the locking post 12, which then slides on the side wall of the slide rod 13. The movement of the locking post 12 causes the first spring 14 to contract, thus releasing the locking post 12 from fixing the screen. The screen can then be removed for cleaning. After cleaning, pressing the connecting rod 17 again causes the locking post 12 to move. The first spring 14 contracts, aligning the locking post 12 with the recessed hole inside the screen frame 4. Then, the connecting rod 17 is released, and the first spring 14 rebounds, locking the locking post 12 into the screen frame 4 to fix the screen again.
[0036] Align the fixing ring 18, then pull up the rotating plate 26 so that one end of the rotating plate 26 rotates inside the connecting block 25, causing the connecting frame 20 to move. When the retaining ring 21 is aligned with the fixing block 19, pull the rotating plate 26 down so that the retaining ring 21 is locked inside the fixing block 19. Due to the fixing of the retaining ring 21, the connecting frame 20 compresses the second spring 23. At the same time, the sliding plate 22 slides inside the vertical groove 24, causing the second spring 23 to be compressed and contracted, thus completing the fixing of the fixing ring 18.
[0037] 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.
