[0001] This invention relates to the field of renewable resource recycling, and in particular to a feeding device and a material sorting equipment. Background Technology

[0002] Traditional recycling industries, due to historical, market, management, raw material characteristics, and technological reasons, often use centralized feeding of materials, which are then transported to manual sorting stations. After sorting, simple mechanical conveying is used, and finally, equipment such as compressors and crushers are used to compress and package the sorted materials. However, centralized feeding greatly reduces the accuracy of sorting and easily leads to material stacking. Furthermore, manual sorting is inefficient, with poor and unstable sorting quality, thus failing to meet market sorting demands.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] This invention provides a feeding device, such as... Figure 1 As shown, the assembly includes a support 10, a material handling component, and a conveying component. Both the material handling component and the conveying component are mounted on the support 10. The support 10 provides support for the material handling component and the conveying component. The material handling component is used to receive and sort materials, while the conveying component receives the materials output by the material handling component. Specifically, the input end of the conveying component is connected to the output end of the material handling component.

[0037] In this embodiment, the material handling component includes a material handling platform 11 and an outer baffle 12. The material handling platform 11 is used to receive and sort materials, and the outer baffle 12 is arranged around the perimeter of the material handling platform 11 to limit the movement range of materials, form a closed material handling area, and prevent materials from falling outside the material handling platform 11 during the material handling process.

[0038] Preferably, such as Figure 1 As shown, the above-mentioned material handling assembly also includes a material handling tray 13, an output tray 14, a first sorting belt 15, and a second sorting belt 16. The material handling tray 13 and the output tray 14 are spaced apart at the bottom of the material handling platform 11, and the material handling tray 13 and the output tray 14 rotate in the same direction. One side of the output tray 14 is connected to the input end of the conveying component. The material handling tray 13 is used to receive and sort the input material. The centrifugal force generated by the rotation of the material handling tray 13 can be used to throw the material onto the output tray 14 in sequence. The output tray 14 is used for feeding material. The centrifugal force generated by the rotation can be used to throw the material onto the output component. Furthermore, the first sorting belt 15 and the second sorting belt 16 are both arranged between the material handling tray 13 and the output tray 14, and the conveying directions of the first sorting belt 15 and the second sorting belt 16 are opposite to each other to assist in the material handling and feeding operations.

[0039] In this embodiment, both the feeding tray 13 and the output tray 14 are convex-facing circular structures. The circular structure facilitates the tangential ejection of materials, and the upward-facing convex surface of the discs prevents material from accumulating in the feeding tray 13 and the output tray 14.

[0040] Optionally, the material feeding tray 13 and the output tray 14 rotate at the same speed, which can avoid the material feeding speed of the material feeding tray 13 being inconsistent with the feeding speed of the output tray 14, thus preventing material blockage and improving the stability of the feeding process.

[0041] For example, the first sorting belt 15 and the second sorting belt 16 have the same specifications and the same operating speed, which improves the stability of the feeding process. In addition, the first sorting belt 15 and the second sorting belt 16 cover the entire sorting platform 11, which effectively avoids the occurrence of non-working areas on the sorting platform 11 and the accumulation of materials.

[0042] In this embodiment, the first sorting belt 15 runs from the sorting tray 13 to the output tray 14, and the second sorting belt 16 runs from the output tray 14 to the sorting tray 13. The first sorting belt 15 can assist in transferring materials from the sorting tray 13 to the output tray 14, and the second sorting belt 16 can re-transport materials that are thrown out of the output tray 14 but fail to enter the output component in time back into the sorting tray 13 to participate in sorting, thus avoiding material blockage.

[0043] For example, the outer baffle 12 includes a fixed baffle 120 and a discharge plate 121. One end of the discharge plate 121 is hinged to the fixed baffle 120, and the other end is snapped into the fixed baffle 120. The opening and closing of the discharge plate 121 is centered on the hinge. Every once in a while, the discharge plate 121 is opened to discharge the miscellaneous materials that are not properly sorted or do not meet the requirements on the material handling platform 11. After the discharge is completed, the discharge plate 121 is closed and the feeding is started.

[0044] Preferably, the discharge plate 121 is located at one end near the material handling tray 13 to facilitate the cleaning of debris.

[0045] Optionally, the outer baffle 12 also includes a movable baffle 122. The movable baffle 122 is provided with a torsion spring at the pivot. One end of the movable baffle 122 is fixedly connected to the fixed baffle 120, and the other end is always in close contact with the conveying component through the torsion spring at the pivot, so that the material can be cut into the conveying component more smoothly.

[0046] In this embodiment, the conveying assembly includes a discharge belt 17 and a conveying baffle 18. The input end of the discharge belt 17 is connected to one side of the output disk 14. The material output from the output disk 14 directly cuts into the discharge belt 17 and is conveyed by the discharge belt 17. The conveying baffle 18 is set on one side of the discharge belt 17 to prevent the material from falling outside the feeding device. Specifically, the other end of the movable baffle 122 is tightly attached to the conveying baffle 18 through a torsion spring at the rotating shaft to ensure that the material can smoothly cut into the discharge belt 17.

[0047] Preferably, the input end of the discharge belt 17 is connected to one side of the output disk 14 along the rotation direction of the output disk 14. This arrangement effectively improves the smoothness of material cutting into the discharge belt 17.

[0048] Optionally, the discharge belt 17 is set close to the sorting platform 11, specifically, it is set on the side close to the second sorting belt 16, so that the material falling during the conveying process can flow back into the sorting tray 13 through the second sorting belt 16, thereby improving the sorting quality.

[0049] In this embodiment, the position of the conveying baffle 18 on the discharge belt 17 is adjustable. Adjusting the position of the conveying baffle 18 along the conveying direction of the discharge belt 17 can control the effective working width of the discharge belt 17. More importantly, this setting can limit the size of the material entering the next process. The center of gravity of the material that is too large will fall outside the discharge belt 17 and will fall onto the second sorting belt 16 during the conveying process, and then flow back into the sorting pool.

[0050] Optionally, the discharge belt 17 can be configured as a two-section belt, namely a first discharge belt 170 near the input end and a second discharge belt 171 near the output end. The first discharge belt 170 and the second discharge belt 171 are controlled by different motors to ensure that the running speed of the second discharge belt 171 is greater than the running speed of the first discharge belt 170, thereby increasing the spacing between materials and facilitating subsequent identification and sorting.

[0051] For example, a reverse plate 19 is connected to one side of the discharge belt 17, and one end of the reverse plate 19 is connected to the outer baffle 12. A partition 190 is provided on the reverse plate 19, and a channel of a preset size can be formed between the partition 190 and the conveying baffle 18. The preset size is the distance between the partition 190 and the conveying baffle 18. This channel can limit the size of the material. Material larger than the width of the channel will be blocked by the partition 190 and remain on the reverse plate 19. In order to allow the material remaining on the reverse plate 19 to flow back to the sorting platform 11 and be discharged from the device when the discharge plate 121 is opened next time, the discharge belt 17 can be tilted. The reverse plate 19 tilts with the discharge belt 17, so that the material can slide back into the sorting platform 11, thereby improving the overall material quality.

[0052] In this embodiment, the feeding device further includes a first driving component. The first driving component controls the material feeding disc 13 and the output disc 14 to rotate in the same direction and at the same speed, drives the first material feeding belt and the second material feeding belt to run in opposite directions at the same speed, drives the discharge plate 121 to rotate and open, and drives the first discharge belt 170 and the second discharge belt 171 to run at different speeds.

[0053] The feeding device provided by this invention can effectively improve the problems of material stacking and small processing volume, improve the material handling effect, and greatly improve the accuracy of subsequent sorting.

[0054] In use, the material to be sorted is fed into the sorting tray 13 of the feeding device. The first drive component controls the rotation of the sorting tray 13 to enable its sorting function. The sorting tray 13 uses centrifugal force to throw the material onto the output tray 14. Some of the material is not thrown directly onto the output tray 14, but is instead transported to the output tray 14 by the first sorting belt 15. The first drive component controls the rotation of the output tray 14 to enable its feeding function, throwing the material onto the discharge belt 17, which then transports it to the next process. The portion of the material thrown out by the output tray 14 is not directly thrown onto the output tray 14. The material can be promptly cut into the discharge belt 17, and this portion of material will be re-transported to the sorting tray 13 by the second sorting belt 16. During the sorting process, the outer baffle 12 is set around the perimeter of the sorting platform 11 to prevent materials from falling outside the device. At the same time, under the action of the conveying baffle 18, materials are prevented from falling and the size of the materials is limited. Materials that are too large or not properly sorted return to the sorting platform 11 along the reversing plate 19. Every once in a while, the first drive component controls the opening of the discharge plate 121 and stops feeding, discharging the waste materials from the sorting platform 11. This realizes the feeding function of the device.

[0055] The present invention also provides a material sorting device, such as... Figure 2 As shown, the device includes the aforementioned feeding device, as well as a conveying device 2, an identification device 3, and a sorting device 4. The conveying device 2 is located downstream of the feeding device and is used to transport the material processed by the feeding device. The identification device 3 is located above the conveying device 2 to identify the material processed by the feeding device. The sorting device 4 is located along the conveying device 2 and is used to sort the material identified by the identification device 3.

[0056] Sorting plates 20 are provided on both sides of the input end of the conveying device 2. The channel formed by the sorting plates 20 gradually narrows. After some of the materials that are tilted on the conveying device 2 pass through the channel, the angle is adjusted, which facilitates subsequent identification and sorting.

[0057] In this embodiment, the conveying device 2 uses a conveyor belt 21 to realize the transportation function, and the conveyor belt 21 is connected to the input end of the discharge belt 17.

[0058] Preferably, the conveyor belt 21 can be configured as a V-shaped belt that is low in the middle and high on both sides, so that the material can automatically center itself on the belt according to its own shape characteristics and weight.

[0059] For example, the identification device 3 includes an identification bracket 30 and an identification component. The identification bracket 30 is mounted on the conveying device 2, and the identification component is disposed on the identification bracket 30. The identification component is a multi-sensor fusion device, including but not limited to a CCD color camera, a near-infrared camera, and a hyperspectral camera. The CCD color camera obtains the color of the material, the near-infrared camera obtains the image of the material, and the hyperspectral camera obtains the spectral map of the material. It should be noted that the aforementioned CCD color camera, near-infrared camera, and hyperspectral camera can be present simultaneously, or only one or two of them can be present, depending on the identification requirements.

[0060] In this embodiment, the identification component includes a position sensor 32, which is positioned in front of other identification components. After the incoming material is detected at its specific position by the position sensor 32, it is then specifically identified by a CCD color camera, a near-infrared camera, a hyperspectral camera, etc., thereby improving the efficiency and accuracy of the identification device 3.

[0061] In other embodiments, the identification component may be disposed on the transport device 2, or it may be disposed separately on the identification bracket 30 and the transport device 2, depending on the specific circumstances.

[0062] In this embodiment, the material sorting equipment is equipped with a control center. The identification information obtained by multiple sensors is transmitted to the control center, and then the control center issues instructions to the sorting device 4 according to the specific classification requirements to complete the sorting.

[0063] The control center is a device that uses multiple sensors to issue instructions to the sorting device 4. It is a mature technology in this field and can directly use commercially available products. Its specific principles and structure will not be elaborated here.

[0064] For example, the sorting device 4 includes a sorting component and a receiving bin 40. The sorting component is located on one side of the conveying device 2, and the receiving bin 40 is located on the other side of the receiving bin 40 corresponding to the sorting component. The sorting component directly acts on the identified materials and sorts the qualified materials into the corresponding receiving bin 40 according to the instructions of the control center.

[0065] Specifically, at least one sorting component is provided, and the corresponding number can be set according to specific needs. For each sorting component, a matching receiving bin 40 is provided on the other side of the conveying device 2.

[0066] In this embodiment, as Figure 3 and Figure 4As shown, a portion of the sorting assembly includes an air jet unit, which comprises two sets of air jets arranged side by side. Each set of air jets includes a first nozzle 41 and a second nozzle 42. The first nozzle 41 is fixedly connected to the sorting assembly, and the second nozzle 42 is rotatably connected below the first nozzle 41. The second nozzle 42 can adjust its angle according to the different shapes of the materials to ensure that the materials can be blown into the corresponding receiving bin 40. The first nozzle 41 and the second nozzle 42 are controlled by a solenoid valve and can be started and stopped simultaneously or alternately to achieve sorting of materials with different shapes.

[0067] Another part of the sorting components includes a pusher unit, such as... Figure 4 As shown, the push cylinder unit includes two push cylinders 43, which are arranged horizontally side by side and are both connected to the sorting component. The two push cylinders 43 move in a straight line and can retract after pushing the material, pushing the material into the corresponding receiving hopper 40. The two push cylinders 43 are controlled by a solenoid valve and can be started and stopped simultaneously or alternately to achieve sorting of materials of different lengths.

[0068] In other embodiments, each jet unit can be equipped with a different number and position of jet components and nozzles. Similarly, the cylinder pusher unit can also be equipped with a different number and position of cylinder pushers 43. The actual setup method depends on the actual needs.

[0069] The sorting mechanism at different locations on the conveying device 2 is equipped with either an air jet unit or a push cylinder unit, depending on the actual usage and requirements. By setting up two sets of actuators, the air jet unit and the push cylinder unit, the sorting of materials of different weights can be achieved.

[0070] In this embodiment, the material sorting equipment also includes a second drive component, which drives the conveyor belt 21 to run.

[0071] The material sorting equipment provided by this invention can accurately classify materials according to specific classification requirements, replacing repetitive manual labor. It has fast sorting efficiency, high and stable sorting quality, and can standby 24 hours a day, operating fully automatically, thus meeting the market's sorting needs.

[0072] In use, the discharge belt 17 delivers the lined materials to the conveyor belt 21. After passing through the channel formed by the sorting plates 20 on both sides at the input end, the angle is adjusted. The materials are then conveyed by the conveyor belt 21 to the position sensor 32 for sensing. The CCD color camera, near-infrared camera, hyperspectral camera, etc., then perform specific identification. The identification information obtained by the above multiple sensors is transmitted to the control center. The detected materials reach the jetting unit and / or pusher unit via the conveyor belt 21. The control center issues instructions based on the identification information, controlling the jetting unit of the sorting component to spray the materials into the corresponding receiving bin 40 with compressed air, or controlling the pusher unit to push the materials into the corresponding receiving bin 40, thus completing the sorting of materials.

[0073] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
