Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, specifically to a mechanical multi-stage screening and arranging device. Background Technology
[0002] With social development, the deep processing of agricultural products is becoming increasingly widespread, especially the processing of dried fruits, which has become so refined that each fruit is carefully selected. Individual processing and packaging of large-sized dried fruits has become a trend. Dried fruits of the same type can vary significantly in size, and during harvesting, debris such as flower stalks, receptacles, and stems are easily introduced. These fruit attachments, like the receptacle, can also detach during processing, creating further obstacles. This poses a significant challenge to refined processing. Given the shortage of labor and rising labor costs, manual selection and plating are no longer sufficient to meet the demands of refined dried fruit processing.
[0003] Therefore, designing a mechanical multi-stage screening and sorting device to improve the production efficiency and pass rate of refined processing of individual dried fruits has become a direction for further improvement. Utility Model Content

[0023] like Figures 1 to 8 As shown, a mechanical multi-stage screening and aligning device includes a frame 1, an elevator 2, a first vibrating screen 3, a material handling device 4, a second vibrating screen 5, a robotic arm 6, a suction cup mechanism 7, a storage hopper 8, a chassis 9, an aligning frame 10, a cavity plate 11, a baffle 12, a cavity 13, a small hole 14, a support 15, a vacuum negative pressure generator 16, an air collecting block 17, a connector 18, a suction nozzle 19, a screen plate 20, a cylinder 21, a linkage shaft 22, a hopper door 23, a mounting base 24, a cleaning fan 25, a motor 26, a crankshaft 27, a mounting block 28, a slide rail 29, a slider 30, a suction port 31, an air gathering pipe 32, and a through groove 33.
[0024] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] like Figures 1 to 8 As shown, a hoist 2 is installed on one side of the frame 1. The output end of the hoist 2 is adapted to be connected to the first vibrating screen 3. A downwardly inclined material handling device 4 is provided below the first vibrating screen 3. The lower end of the material handling device 4 is adapted to be connected to the second vibrating screen 5. A storage hopper 8 is provided below the output end of the second vibrating screen 5. A mechanical arm 6 is provided at intervals on one side of the material handling device 4. The output end of the mechanical arm 6 is fixedly connected to the suction cup mechanism 7. The width of the suction cup mechanism 7 is equal to the width of the inner side of the material handling device 4.
[0027] The material handling device 4 includes a chassis 9, an alignment frame 10, a transverse movement mechanism, a cavity tray 11, baffles 12, and a buffer mechanism. The chassis 9, tilted downwards, is fixed to the frame 1. Multiple through slots 33 are formed on the chassis 9. The alignment frame 10 is circumferentially covered by the chassis 9. A transverse movement mechanism is located within the alignment frame 10, with its upper end slidably connected to the cavity tray 11. Baffles 12 are located on both sides of the cavity tray 11. The upper end of the cavity tray 11 is adapted to the buffer mechanism, which is positioned directly below the first vibrating screen 3. The cavity tray 11 has multiple linearly and equally spaced cavity slots 13. At least three small holes 14 are located at the bottom of each cavity slot 13, communicating with the interior of the alignment frame 10. The device also includes a dust removal fan 25. The output end of the dust removal fan 25 is inserted into the through slots 33 via an air supply pipe, communicating with the interior of the alignment frame 10 (the air supply pipe is not shown in the attached diagram but is a common commercially available air supply pipe). When the impurity removal fan 25 is turned on, the wind energy removes impurities from the surface of the material in the cavity 13 through the small hole 14.
[0028] The suction cup mechanism 7 includes a support 15, a vacuum negative pressure generator 16, an air collecting block 17, a connector 18, and a suction nozzle 19. The output end of the robotic arm 6 is fixedly connected to the upper end of the support 15. Multiple sets of air collecting blocks 17 are evenly arranged on the support 15. The input end of the air collecting block 17 is adapted to the vacuum negative pressure generator 16. The output end of the air collecting block 17 is connected to the suction nozzle 19 through the connector 18. The number of suction nozzles 19 arranged horizontally is equal to the number of slots 13 arranged horizontally. When there are two materials in the slot 13, the suction nozzle 19 will only suck up one material, which greatly improves the pass rate of single-piece alignment. The suction nozzle 19 includes an integrally formed suction port 31 and an air concentrator 32. The diameter of the suction port 31 is larger than the diameter of the air concentrator 32. The air concentrator 32 is wavy, which allows for more precise suction of materials.
[0029] The buffer mechanism includes a sieve plate 20, a cylinder 21, a linkage shaft 22, a hopper door 23, and a mounting base 24. The sieve plate 20 is sandwiched between the front parts of the baffles 12. The cylinder 21 is fixed to the outside of the sieve plate 20. The output end of the cylinder 21 is connected to the linkage shaft 22 for transmission. The hopper door 23 passes through the linkage shaft 22 and is rotatably connected to the connection between the sieve plate 20 and the acupoint plate 11. Mounting bases 24 are provided on both sides of the hopper door 23 and are fixed to the baffles 12. The buffer mechanism facilitates the initial alignment of materials, which roll down the sieve plate 20 onto the acupoint plate 11.
[0030] The transverse movement mechanism includes a motor 26, a crankshaft 27, a mounting block 28, a slide rail 29, and a slider 30. The motor 26, crankshaft 27, and mounting block 28 are mounted on the chassis 9. The output end of the motor 26 is connected to the crankshaft 27 for transmission. The upper end of the crankshaft 27 is fitted and connected to the lower center of the acupoint plate 11. The slide rail 29 is fixedly mounted on the mounting block 28, and the slider 30 slides along the slide rail 29. The upper end of the slider 30 is fixedly connected to the bottom of the acupoint plate 11. The motor 26 drives the crankshaft 27 to move, causing the acupoint plate 11 to swing laterally along the slide rail 29, facilitating better shaking of materials into the acupoint groove 13.
[0031] The working principle of this utility model is as follows:
[0032] When the unremoved dried fruit is poured into the elevator 2, the elevator 2 lifts the material to a certain height and then it falls into the first vibrating screen 3. The first vibrating screen 3 initially separates the product material from the impurities through vibration. Then, the product material falls into the screen plate 20 through the outlet of the first vibrating screen 3. The cavity plate 11 is driven by the motor 26 to drive the crankshaft 27 to swing laterally along the slide rail 29. During the swinging process, the product material rolls into the cavity 13 along the hopper door 23 by gravity. The operator can set the time for each cycle by observing when the product material basically fills the cavity 13. The interval between each horizontal swing continues until the product material fills the cavity 13. Once the cavity 13 is full, the product material is sucked up by the suction nozzle 19 of the suction mechanism 7 driven by the robotic arm 6 and transferred to the carrier of the next process, thus completing the screening and arrangement of the material. Excess material and unremoved debris fall into the second vibrating screen 5 under the action of gravity through the outlet of the cavity plate 11 for further screening. Excess material then falls into the storage hopper 8 below the elevator through the second vibrating screen 5. This cycle is repeated to perform multi-stage screening and arrangement of the material.
[0033] This invention achieves three-stage impurity removal through two vibration-based impurity removal processes before and after material handling, as well as wind-based impurity removal, which improves the efficiency and pass rate of dried fruit sorting. The automatic cycle of material screening and sorting effectively reduces labor costs.
[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Therefore, any modifications, equivalent changes, or improvements made in accordance with the claims of this utility model shall still fall within the scope of this utility model.
