Description

Technical Field

[0001] This utility model belongs to the field of food production technology, specifically a screening device for food production. Background Technology

[0002] Food production is the process of processing, handling, and blending various raw and auxiliary materials to produce products that can be consumed by humans. Screening devices are important equipment in food processing, separating materials of different particle sizes through screens, removing impurities, and grading particles.

[0003] According to a search, patent document CN222267786U discloses a food production screening device, including a workbench with a fixed frame connected to it. A limiting groove is formed within the fixed frame, and a moving device is slidably connected within the limiting groove. The moving device includes a moving plate, and a fixed disk is rotatably connected within a circular groove on the side of the moving plate. An eccentric wheel is rotatably connected within the fixed disk. This food production screening device, by setting the limiting groove and baffle, enables the motor to rotate synchronously, driving a first rotating shaft, eccentric wheel, and cam. This, in turn, causes the fixed disk to rotate within the moving plate, resulting in the moving plate reciprocating within the limiting groove. This, in turn, drives the connecting rod and the screen box to reciprocate horizontally. This allows the device to move the screen box bidirectionally in both horizontal and vertical directions, avoiding clogging of the screen holes due to unidirectional shaking during screening, thus ensuring the screening efficiency of the device.

[0004] The aforementioned comparative documents also have the following shortcomings: the food materials remaining in the sieve box of the aforementioned comparative documents are difficult to pour out. The sieve box is surrounded on all sides, making it difficult to pour out large pieces of food materials inside the sieve box. Manual cleaning is required, which consumes a lot of time.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-6 As shown, this utility model provides a technical solution:

[0023] A screening device for food production includes a base plate 1, an equipment box 2 fixedly connected to the top of the base plate 1, a vibration component mounted on the equipment box 2, a pair of guide rails 3 fixedly connected to one side of the equipment box 2, connecting frames 4 slidably connected to each of the guide rails 3, a pair of adjusting components mounted at the bottom of the connecting frames 4, a screen box 5 rotatably connected to the connecting frames 4, an opening on one side of the screen box 5, a pair of support blocks 6 fixedly connected to one side of the screen box 5, a rotating shaft rotatably connected to one of the support blocks 6, one end of the rotating shaft rotatably connected to the other support block 6, a rotating plate 7 coaxially fixedly connected to the rotating shaft, an opening / closing door 8 fixedly connected to the bottom of the rotating plate 7, and a rotating component mounted on one side of the screen box 5 for pouring food materials into it. Inside the sieve box 5, the vibration component is activated. The vibration component drives the connecting frame 4 to slide back and forth on a pair of guide rails 3. The connecting frame 4 drives the sieve box 5 to perform screening. At this time, the opening and closing door 7 closes, blocking the opening on one side of the sieve box 5, so that the food materials are fully screened. After screening, the vibration component stops working, and the rotating component drives the rotating shaft to rotate on the support block 6. The rotating shaft drives the opening and closing door 8 to rotate and open through the rotating plate 7. The adjusting component drives the sieve box 5 to rotate a certain angle on the connecting frame 4, so that the large pieces of food materials remaining in the sieve box 4 slide out through the opening on one side of the sieve box 5, reducing the intensity and time cost of manual cleaning. The vibration component can be restarted while dumping large pieces of food materials, which greatly improves the dumping efficiency.

[0024] The vibration assembly includes a servo motor 9, which is fixedly connected to one side of the equipment box 2. The output end of the servo motor 9 passes through the equipment box 2 and is rotatably connected to it. A turntable 10 is coaxially fixedly connected to the output end of the servo motor 9. A guide rod 11 is fixedly connected to one side of the turntable 10 away from the axis. A connecting rod 12 is fixedly connected to one side of the connecting frame 4. A guide block 13 is fixedly connected to one end of the connecting rod 12. A guide groove is opened on one side of the guide block 13, which is adapted to the guide rod 11. A through movable groove is opened on the equipment box 2, which is adapted to the connecting rod 12. When the servo motor 9 is started, the output end of the servo motor 9 drives the turntable 10 to rotate. The turntable 10 drives the guide rod 11 to make a circular motion. The guide rod 11 slides in the guide groove on one side of the guide block 13, so that the guide block 13 reciprocates. The guide block 13 drives the connecting frame 4 to move together through the connecting rod 12.

[0025] The adjustment assembly includes an L-shaped connecting rod 14, which is fixedly connected to the bottom of the connecting frame 4. One end of the L-shaped connecting rod 14 is rotatably connected to a rotating seat 15. A hydraulic cylinder 16 is fixedly connected to the rotating seat 15. A connecting block 17 is fixedly connected to the output end of the hydraulic cylinder 16. A connecting column 18 is rotatably connected to the connecting block 17. One end of the connecting column 18 is fixedly connected to the screen box 5. When the hydraulic cylinder 16 is started, the output end of the hydraulic cylinder 16 pulls the connecting column 18 through the connecting block 17, causing the screen box 5 to rotate on the connecting frame 4.

[0026] The rotating assembly housing 19 is fixedly connected to one side of the screen box 5. A worm gear 20 is rotatably connected to the housing 19. A handwheel 21 is coaxially fixedly connected to the top of the worm gear 20. One end of the rotating shaft passes through the housing 19 and is rotatably connected to it. A worm wheel 22 is coaxially fixedly connected to the other end of the rotating shaft. The worm wheel 22 meshes with the worm gear 20. The handwheel 21 drives the worm gear 20 to rotate on the housing 19. The worm gear 20 drives the rotating shaft to rotate through the meshing worm wheel 22.

[0027] A guide plate 23 is fixedly connected to one side of the sieve box 5, and large pieces of food material slide down along the guide plate 23.

[0028] The working principle of this utility model is as follows:

[0029] Start the servo motor 9. The output of the servo motor 9 drives the turntable 10 to rotate. The turntable 10 drives the guide rod 11 to make a circular motion. The guide rod 11 slides in the guide groove on one side of the guide block 13, so that the guide block 13 reciprocates. The guide block 13 drives the connecting frame 4 to slide back and forth on a pair of guide rails 3 through the connecting rod 12. The connecting frame 4 drives the screen box 5 to screen. At this time, the opening and closing door 7 closes, blocking the opening on one side of the screen box 5, and pouring the food material into the screen box 5 so that the food material is fully screened.

[0030] After screening, the servo motor 9 is turned off, and the worm gear 20 is rotated on the housing 19 by the handwheel 21. The worm gear 20 rotates on the support block 6 by the worm wheel 22 that meshes with it. The rotating shaft rotates on the support block 6 by the rotating plate 7. The opening and closing door 8 is opened by the rotating plate 7. The hydraulic cylinder 16 is started. The output end of the hydraulic cylinder 16 pulls the connecting column 18 through the connecting block 17, so that the screen box 5 rotates on the connecting frame 4 at a certain angle. Large pieces of food material remaining in the screen box 4 slide out through the opening on one side of the screen box 5. The large pieces of food material slide down along the guide plate 23, reducing the intensity and time cost of manual cleaning. The servo motor 9 can be restarted while dumping the large pieces of food material, which greatly improves the dumping efficiency.

[0031] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
