[0002] Nutritional food raw materials refer to natural or processed raw materials with specific nutritional value or health benefits that can be used to produce functional foods, health foods, and foods for special medical purposes. Nutritional food raw material pretreatment equipment is an important part of food processing, which can improve the efficiency of subsequent processing and product quality. Vibrating screens are often used to screen and remove impurities from nutritional food raw materials.

[0003] In the prior art, the vibrating screen used for pretreatment of nutritional food raw materials applies vibration force to the screening frame above through the vibrating seat at the bottom driven by the vibrating motor, thereby screening the raw materials inside the screening frame. Since the food raw materials are of different sizes, different aperture screen plates are required. Traditional screen plates are relatively inconvenient to disassemble, resulting in a long replacement time. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic impurity removal pretreatment device for nutritional food raw materials, in order to solve the problem mentioned in the background art that food raw materials of different sizes require sieve plates with different apertures, and that traditional sieve plates are inconvenient to disassemble and have a long replacement time.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes a vibrating screen base, the top of which is fixedly connected to the bottom of the collection chamber, one side of which is fixedly connected to one side of the first discharge frame, a screening mechanism on the top of the collection chamber, the screening mechanism including a screening frame, a second discharge frame, a positioning block, a locking frame, a moving groove, a moving plate, a locking block, a connecting spring, and a moving rod; a screen plate mechanism inside the screening mechanism, the screen plate mechanism including a screen mesh, a concave block, a connecting plate, a fixing block, and a locking groove; an elastic ball assembly on the top of the screen plate mechanism, the elastic ball assembly including a fixing tube, a hollow groove, an elastic ball body, a threaded groove, a threaded block, and a knob; and a protective cover on the top of the screening mechanism.

[0006] In a preferred embodiment, the top of the collection chamber is fixedly connected to the bottom of the screening frame by bolts, one side of the screening frame is fixedly connected to one side of the second discharge frame, the inner wall of the screening frame is fixedly connected to one side of the positioning block, and the top of the screening frame is fixedly connected to the bottom of the protective cover by bolts.

[0007] In a preferred embodiment, both sides of the inner wall of the screening rack are fixedly connected to the outer wall of the locking frame, and the locking frame has a movable groove inside, with the inner wall of the movable groove being movably connected to the outer wall of the movable plate.

[0008] In a preferred embodiment, the top of the movable plate is fixedly connected to the bottom of the locking block, and one side of the movable plate is fixedly connected to one end of the connecting spring, while the other end of the connecting spring is fixedly connected to the inner wall of the movable groove. One side of the movable plate is fixedly connected to one side of the movable rod, and the movable rod extends to the outside of the locking frame.

[0009] In a preferred embodiment, the inner wall of the screening rack is movably connected to the outer wall of the screen, the top of the screen is fixedly connected to the bottom of the concave block, and the inner wall of the concave block is movably connected to the outer wall of the positioning block.

[0010] In a preferred embodiment, the top of both sides of the screen is fixedly connected to the bottom of the connecting plate, and the top of the connecting plate is fixedly connected to the bottom of the fixing block. The fixing block has a slot inside, and the inner wall of the slot is movably connected to the outer wall of the block.

[0011] In a preferred embodiment, the top of the screen is fixedly connected to the bottom of the fixed tube, and the inside of the fixed tube is provided with a hollow groove, the inner wall of the hollow groove is movably connected to the outer wall of the elastic ball body, and the top of the hollow groove is provided with a threaded groove.

[0012] In a preferred embodiment, the inner wall of the threaded groove is threadedly connected to the outer wall of the threaded block, and the top of the threaded block is fixedly connected to the bottom of the knob.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model involves pressing the moving rod to move the moving plate, simultaneously stretching the connecting spring. As the moving plate moves, the locking block moves, allowing it to move within the slot and freeing itself from its limit position. After removing the screen, a screen with a suitable aperture is placed inside the screening rack via the positioning of the concave block and the positioning block. The flexibility of the screen allows the fixing block to be positioned above the locking frame. Pressing the moving rod causes the locking block to pass through the slot. Releasing the moving rod causes the locking block to move through the reset of the connecting spring, locking it onto the top of the fixing block and stabilizing the screen. This eliminates the need for traditional bolt fixing, reducing the complexity of screen disassembly and assembly, and thus reducing screen replacement time.

[0015] 2. In this utility model, rotating the knob causes the threaded block to rotate inside the threaded groove, causing the threaded block to move upward, thereby increasing the height of the elastic ball body inside the hollow groove, thus reducing the bouncing frequency. Conversely, moving the threaded block increases the bouncing frequency. By moving the threaded block, the vibration frequency of the elastic ball body can be adjusted, making the elastic ball body suitable for different situations, while reducing the damage to the screen caused by the bouncing of the elastic ball body.

[0026] In one embodiment, the top of the collection chamber 2 is fixedly connected to the bottom of the screening frame 401 by bolts, and one side of the screening frame 401 is fixedly connected to one side of the second discharge frame 402. The inner wall of the screening frame 401 is fixedly connected to one side of the positioning block 403, and the top of the screening frame 401 is fixedly connected to the bottom of the protective cover 7 by bolts.

[0027] Specifically: the positioning block 403 ensures the effective installation and positioning of the screen 501, and the protective cover 7 reduces dust scattering and raw material falling during screening.

[0028] In one embodiment, both sides of the inner wall of the screening rack 401 are fixedly connected to the outer wall of the locking rack 404, and the locking rack 404 has a moving groove 405 inside, and the inner wall of the moving groove 405 is movably connected to the outer wall of the moving plate 406.

[0029] Specifically: the flexibility of the screen 501 allows the fixing block 504 to be placed above the locking frame 404.

[0030] In one embodiment, the top of the movable plate 406 is fixedly connected to the bottom of the locking block 407, and one side of the movable plate 406 is fixedly connected to one end of the connecting spring 408, and the other end of the connecting spring 408 is fixedly connected to the inner wall of the movable groove 405. One side of the movable plate 406 is fixedly connected to one side of the movable rod 409, and the movable rod 409 extends to the outside of the locking frame 404.

[0031] Specifically: the moving rod 409 moves the locking block 407 by resetting the connecting spring 408, so that the locking block 407 is locked on the top of the fixed block 504.

[0032] In one embodiment, the inner wall of the screening rack 401 is movably connected to the outer wall of the screen 501, the top of the screen 501 is fixedly connected to the bottom of the concave block 502, and the inner wall of the concave block 502 is movably connected to the outer wall of the positioning block 403.

[0033] Specifically: The concave block 502 and the positioning block 403 facilitate the positioning of the screen 501 during installation.

[0034] In one embodiment, the top of both sides of the screen 501 is fixedly connected to the bottom of the connecting plate 503, and the top of the connecting plate 503 is fixedly connected to the bottom of the fixing block 504. The fixing block 504 has a slot 505 inside, and the inner wall of the slot 505 is movably connected to the outer wall of the block 407.

[0035] Specifically: By setting up the slot 505 and the block 407, the traditional bolt fixing method is eliminated, reducing the cumbersome disassembly and assembly of the screen 501, and thus reducing the replacement time of the screen 501.

[0036] In one embodiment, the top of the screen 501 is fixedly connected to the bottom of the fixed tube 601, and a hollow groove 602 is provided inside the fixed tube 601. The inner wall of the hollow groove 602 is movably connected to the outer wall of the elastic ball body 603, and a threaded groove 604 is provided at the top of the hollow groove 602.

[0037] Specifically: by moving the threaded block 605, the vibration frequency of the elastic ball body 603 is adjusted, making the elastic ball body 603 suitable for different situations, while reducing the damage to the screen 501 caused by the elastic ball body 603 bouncing.

[0038] In one embodiment, the inner wall of the threaded groove 604 is threadedly connected to the outer wall of the threaded block 605, and the top of the threaded block 605 is fixedly connected to the bottom of the knob 606.

[0039] Specifically: Rotating the knob 606 causes the threaded block 605 to rotate inside the threaded groove 604, causing the threaded block 605 to move upward.

[0040] Working principle: Food raw materials are placed into the screening rack 401 through the inlet at the top of the protective cover 7. The device is activated, and the raw materials are then screened and impurities removed through the screen 501. Impurities and screened raw materials are discharged through the first discharge rack 3 and the second discharge rack 402. When the screen 501 vibrates, the elastic ball body 603 bounces up and down inside the hollow groove 602, impacting the screen 501. This impact clears the impurities clogging the screen holes. In actual use, if there are few impurities inside the screen holes, rotating the knob 606 rotates the threaded block 605 inside the threaded groove 604, causing the threaded block 605 to move upwards. This increases the height of the elastic ball body 603 within the hollow groove 602, thus reducing the bounce frequency. Conversely, it increases the bounce frequency. This process is applied to different raw materials. When screening materials, screens 501 with different mesh sizes need to be replaced. Pressing the moving rod 409 moves the moving plate 406, which in turn stretches the connecting spring 408. As the moving plate 406 moves, the locking block 407 moves, allowing it to move inside the slot 505 and free itself from its limit. After removing the screen 501, a screen 501 with a suitable mesh size is placed inside the screening frame 401 by the positioning of the concave block 502 and the positioning block 403. Due to the flexibility of the screen 501, the fixing block 504 is positioned above the locking frame 404. Pressing the moving rod 409 causes the locking block 407 to pass through the slot 505. Releasing the moving rod 409 causes the locking block 407 to move by the reset of the connecting spring 408, locking it at the top of the fixing block 504 and stabilizing the screen 501.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
