Description

Technical Field

[0001] This disclosure relates to the field of material sorting, specifically to an identification device and a sorting machine. Background Technology

[0002] In some material sorting scenarios, such as food sorting, materials often overlap or are close together, which may lead to inaccurate material identification and detection, reduced material sorting accuracy, decreased sorting output, and reduced overall equipment reliability. Utility Model Content

[0003] To overcome the problems existing in the related technologies, an exemplary embodiment of the present disclosure provides an identification device in the first aspect, wherein the identification device includes: a first transmission mechanism for receiving and conveying materials; a second transmission mechanism disposed downstream of the first transmission mechanism for receiving the materials conveyed by the first transmission mechanism and discharging the materials, wherein the transmission speed of the second transmission mechanism is greater than the transmission speed of the first transmission mechanism; a detection mechanism for detecting the materials conveyed by the second transmission mechanism; and a first steel curtain assembly disposed above the first or second transmission mechanism and upstream of the detection mechanism for separating materials stacked vertically.

[0004] In some embodiments, the detection mechanism includes an X-ray source for emitting X-rays to identify materials, and the detection mechanism is covered by a cover plate; a first steel curtain assembly is disposed on one side of the cover plate to prevent X-ray leakage; the identification device further includes a second steel curtain assembly disposed on the opposite side of the cover plate from the first steel curtain assembly to prevent X-ray leakage.

[0005] In some embodiments, the first steel curtain assembly and / or the second steel curtain assembly includes: two hooks, each fixedly connected to a cover plate, wherein each hook has a notch; a pivot, both ends of which are detachably supported at the notches of the two hooks; and a plurality of rotating slats, hinged side by side to the pivot and capable of swinging about the pivot to separate overlapping materials.

[0006] In some embodiments, the rotating shaft further includes two limiting grooves, respectively disposed at both ends of the rotating shaft, which cooperate with the notch of the hook to prevent the rotating shaft from moving axially.

[0007] In some embodiments, the rotating shaft further includes: a rotating handle rotatably connected to the end of the rotating shaft, wherein the rotating handle is capable of rotating relative to the rotating shaft in the radial direction of the rotating shaft; and a limiting member fixedly disposed at both ends of the rotating shaft for fixing the rotating handle.

[0008] In some embodiments, the first transmission mechanism includes: a first belt conveyor for conveying materials; two side guards disposed on both sides of the first belt conveyor along the conveying direction of the first belt conveyor; and one or more partition baffles disposed above the first belt conveyor along the conveying direction of the first belt conveyor, wherein the side guards and partition baffles together form multiple material conveying channels so that the materials are transported to the second transmission mechanism along the multiple material conveying channels.

[0009] Secondly, this disclosure also provides a sorting machine, comprising: an identification device as described in any of the above aspects, used for conveying and separating materials, wherein the detection mechanism in the identification device is capable of detecting the category of the materials; and a sorting device, disposed at the discharge end of the identification device, used for sorting the materials according to the detection results of the detection mechanism.

[0010] In some embodiments, the sorting device includes: a receiving belt disposed downstream of the second conveying mechanism for receiving and conveying the material discharged by the second conveying mechanism; a sorting belt having one end for receiving the material from the receiving belt and the other end for discharging the material; and a driving device connected to the sorting belt for driving the sorting belt to rotate so that the material is sorted to different positions.

[0011] In some embodiments, the sorting machine further includes a collection device for collecting materials of different categories after being sorted by the sorting device.

[0012] In some embodiments, the collecting device includes: a multi-layer belt arranged vertically to receive different types of materials and discharge the materials.

[0013] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0014] This disclosure provides an identification device that improves the efficiency and accuracy of material detection. A second transmission mechanism is set at a higher speed than the first transmission mechanism, creating a speed difference when continuously conveyed materials enter the downstream section. This effectively increases the spacing between materials, avoiding blind spots caused by materials being too close together. A first steel curtain assembly upstream of the detection mechanism separates stacked materials, preventing obstruction caused by material overlap and ensuring that each material enters the detection area independently. The combined effect of these two mechanisms allows for clearer and more comprehensive material detection, effectively improving identification and sorting accuracy, reducing the probability of missed or false detections. It ensures continuous material transport to maintain processing efficiency while improving detection reliability through optimized material conditions, thus enhancing the overall practicality and economic benefits of the equipment.

[0027] The following describes specific embodiments of this disclosure. It should be noted that, in order to provide a concise description, this specification cannot exhaustively describe all features of the actual embodiments. It should be understood that, in the actual implementation of any embodiment, just as in any engineering or design project, various specific decisions are often made to achieve the developer's specific goals and to meet system-related or business-related constraints, and this can change from one embodiment to another. Furthermore, it is understood that although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content of this disclosure, some design, manufacturing, or production modifications based on the technical content disclosed in this disclosure are merely conventional technical means and should not be construed as insufficient content of this disclosure.

[0028] Unless otherwise defined, the technical or scientific terms used in the claims and description shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar words used in the specification and claims of this utility model patent application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. The terms "an" or "a" and similar words do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms "comprising" or "including" and similar words mean that the element or object preceding "comprising" or "including" encompasses the element or object listed following "comprising" or "including" and its equivalents, and do not exclude other elements or objects. The terms "connected" or "linked" and similar words are not limited to physical or mechanical connections, nor are they limited to direct or indirect connections.

[0029] In some scenarios, such as the sorting of food materials, problems with detection accuracy and efficiency often arise due to poor material transport conditions. During continuous transport, materials may be packed tightly together, creating blind spots in the detection process. Furthermore, materials like meat tend to stack during transport, making it difficult for the identification device to effectively identify overlapping portions. This leads to high rates of missed and false detections, decreased sorting accuracy, lower sorting output, and reduced economic benefits.

[0030] To overcome the problems existing in related technologies, exemplary embodiments of this disclosure provide an identification device 100, such as... Figure 1 , Figure 2 , Figure 10As shown, this can be applied to a sorting machine, which can be used to sort materials such as food. It can include an identification device 100 and a sorting device 200. The identification device 100 can be used to convey and separate materials, and the detection mechanism 130 in the identification device 100 can detect the category of the material. The sorting device 200 can be located at the discharge end of the identification device 100 and is used to sort the materials according to the detection results of the detection mechanism 130, thus separating materials of different categories.

[0031] like Figure 1 , Figure 2 As shown, the identification device 100 may include: a first transmission mechanism 110, a second transmission mechanism 120, a detection mechanism 130, and a first steel curtain assembly 140.

[0032] like Figure 1 , Figure 6 As shown, the first conveying mechanism 110 is used to receive and convey materials. The first conveying mechanism 110, serving as the material input end of the identification device 100, may include: a first belt conveyor mechanism 111, a drive motor, a driving roller, a driven roller, and side guards 112, etc. The first belt conveyor mechanism 111 can be sleeved between the driving roller and the driven roller, and the drive motor can be connected to the driving roller to provide power. The side guards 112 can be symmetrically arranged on both sides of the first belt conveyor mechanism 111 to form a material conveying channel, used to limit the width range of material transmission.

[0033] The first transmission mechanism 110 can be located at the uppermost end of the identification device 100. The output end of the first transmission mechanism 110 is close to the second transmission mechanism 120 and can be aligned and connected with the input end of the second transmission mechanism 120 to ensure that the material can be transferred smoothly.

[0034] like Figure 1 As shown, the second transmission mechanism 120 can be located downstream of the first transmission mechanism 110, and is used to receive the material conveyed by the first transmission mechanism 110 and discharge the material. The second transmission mechanism 120 has a similar structure to the first transmission mechanism 110 and can be a belt or the like. The input end of the second transmission mechanism 120 can be connected and aligned with the output end of the first transmission mechanism 110, so that the material can transition from the first transmission mechanism 110 to the second transmission mechanism 120, thus preventing the material from falling or getting stuck.

[0035] The transmission speed of the second transmission mechanism 120 is greater than that of the first transmission mechanism 110. When adjacent materials enter the second transmission mechanism 120 from the first transmission mechanism 110, the preceding material can instantly change from a lower speed to a higher speed. At this time, the speed difference will cause the preceding material to move away from the following material. When the following material enters the second transmission mechanism 120 from the first transmission mechanism 110, the preceding material has already been running at a higher speed on the second transmission mechanism 120 for a period of time. At this time, a gap has been formed between the preceding and following materials, thus realizing the separation of adjacent materials.

[0036] like Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the detection mechanism 130 is used to detect the material conveyed by the second transmission mechanism 120. The detection mechanism 130 may include a radiation source 131 and a radiation receiver 132, which may be respectively positioned above and below the second transmission mechanism 120. When the material on the second transmission mechanism 120 passes through the detection mechanism 130, the density of the material and any foreign matter inside will affect the intensity of the radiation to varying degrees, thereby detecting whether the material meets the requirements for material sorting. The detection mechanism 130 may also be configured as a color sorter, a camera, etc., to identify and detect the material to be sorted.

[0037] like Figure 1 , Figure 2 As shown, the first steel curtain assembly 140 can be positioned above the first conveying mechanism 110 or the second conveying mechanism 120, and upstream of the detection mechanism 130, for separating stacked materials. The first steel curtain assembly 140 is detachably installed on the first conveying mechanism 110 or the second conveying mechanism 120 for easy disassembly and cleaning. When the stacked materials move along the conveyor belt to below the steel curtain, the bottom of the steel curtain slightly presses down or obstructs the upper layer of materials. The forward force of the conveyor belt combined with the resistance between the steel curtain and the upper layer of materials can be used to push or flatten the materials, ensuring that all materials continue to be conveyed in a single layer, preventing overlapping parts from being missed by the detection mechanism 130. The first steel curtain assembly 140 can be positioned upstream of the detection mechanism 130, ensuring that materials separated by the first steel curtain assembly 140 can directly enter the detection area of ​​the detection mechanism 130.

[0038] In some embodiments, such as Figure 1As shown, the first steel curtain assembly 140 can be positioned above the first transmission mechanism 110, close to its output end. This allows for the early separation of initially stacked materials. The separated single-layer material can then undergo secondary separation due to the speed difference between the belts. By pre-separating the stacked material and utilizing the subsequent gap created by the speed difference, the material entering the detection mechanism 130 passes through the detection area in a single layer with no adjacent materials. This avoids signal interference or missed detection due to material overlap, improving the accuracy of the detection mechanism 130 in identifying materials and internal foreign objects.

[0039] In some embodiments, the first transmission mechanism 110 receives materials as an input and conveys them to the downstream second transmission mechanism 120. The first steel curtain assembly 140, located above the first transmission mechanism 110, separates the stacked materials during the conveying process, pushing aside and flattening the upper layer of materials so that the materials continue to be conveyed in a single layer. The single layer of materials transitions from the first transmission mechanism 110 to the second transmission mechanism 120, which has a faster transmission speed. The speed difference causes the preceding material to quickly move away from the following material, forming a gap and achieving the separation of the materials that are close together. After two separations, the single layer of materials that are not close together enters the detection mechanism 130 area with the second transmission mechanism 120. By observing the different effects of the materials and internal foreign objects on the radiation intensity, the detection mechanism determines whether the materials meet the requirements, providing a reliable basis for subsequent sorting.

[0040] In this embodiment, the identification device 100 includes a first transmission mechanism 110, a second transmission mechanism 120, a detection mechanism 130, and a first steel curtain assembly 140. The speed difference between the second transmission mechanism 120 and the first transmission mechanism 110 automatically widens the gap between adjacent materials. Combined with the separation effect of the first steel curtain assembly 140 on stacked materials, the materials enter the detection area in a single layer and independently, completely eliminating the detection blind spots caused by overlapping and close proximity of materials in traditional devices. The detachable design of the first steel curtain assembly 140 facilitates cleaning and maintenance, reducing equipment downtime. Overall, the device balances processing efficiency, detection accuracy, and ease of maintenance, effectively improving identification and sorting accuracy, reducing inaccurate identification and sorting due to material overlap, and increasing the reliability and economic benefits of the setup.

[0041] In some embodiments, such as Figure 7As shown, the detection mechanism 130 may include a radiation source 131 for emitting radiation to identify materials. A cover plate 133 may be provided around the detection mechanism 130. The radiation source 131 may be fixed to the top or side of the cover plate 133, with its radiation emission direction aligned with the material conveying surface of the second transmission mechanism 120, and may cooperate with the radiation receiving device 132 below. The cover plate 133 may be a closed shell structure, located around the periphery of the second transmission mechanism 120, and may be lined with lead sheeting to shield the X-rays scattered by the radiation source 131, effectively preventing radiation leakage.

[0042] like Figure 1 , Figure 2 As shown, the first steel curtain assembly 140 can be disposed on one side of the cover plate 133 to prevent radiation leakage. The first steel curtain assembly 140 can be located on the entrance side of the material entering the detection area, and the bottom of the first steel curtain assembly 140 can be disposed close to the surface of the conveyor belt of the first transmission mechanism 110, forming a protective barrier with the cover plate to prevent radiation leakage at the material inlet.

[0043] like Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the identification device 100 may further include a second steel curtain assembly 150, disposed on the opposite side of the cover plate 133 and the first steel curtain assembly 140, for preventing radiation leakage. The second steel curtain assembly 150 may be disposed on the material outlet side corresponding to the cover plate 133, and may correspond to the first steel curtain assembly 140, the three forming a closed protective space. The cover plate 133 covers the core area of ​​the detection mechanism 130, the first steel curtain assembly 140 seals the radiation gap when material enters the detection area, and the second steel curtain assembly 150 seals the exit of material from the detection area, the three forming a complete radiation protection barrier to prevent radiation leakage.

[0044] In this embodiment, the X-ray source 131 of the detection mechanism 130 cooperates with the X-ray receiving device 132 to achieve identification by utilizing the density difference of the material through which the X-rays penetrate. The coordinated arrangement of the cover plate 133, the first steel curtain assembly 140, and the second steel curtain assembly 150 constructs all-round radiation protection. The cover plate 133, as a protective component, uses a closed shell combined with internal lead sheeting to effectively block the X-rays from the X-ray source 131 and prevent radiation leakage. The first steel curtain assembly 140 cooperates with the conveyor belt on the material inlet side to form a continuous protective barrier with the cover plate 133. The second steel curtain assembly 150 is symmetrically arranged on the outlet side to avoid radiation leakage when the material leaves. The three components work together to form a closed space, eliminating operational safety hazards. This approach balances detection accuracy, operational safety, and production continuity, providing a reliable guarantee for efficient industrial-scale detection.

[0045] In some embodiments, such as Figures 3 to 5 As shown, the first steel curtain assembly 140 may include: two hooks 141, a pivot 142, and a plurality of rotating slats 143.

[0046] Two hooks 141 are fixedly connected to the cover plate 133, and each hook 141 has a notch 1411. The hooks 141 have a plate-like structure, can be two in number, and can have mounting holes, and can be fixedly connected to the cover plate 133 by bolts or the like. Each hook 141 can have a notch 1411, which can be L-shaped, and can be used to fix the rotating shaft 142.

[0047] The pivot 142 is detachably supported at both ends by the notches of the two hooks 141. As the core supporting component of the first steel curtain assembly 140, the pivot 142 is cylindrical in shape and can be made of high-strength stainless steel, with a diameter slightly smaller than the width of the notches in the hooks 141. Its length matches the spacing between the two hooks 141, ensuring that both ends can be inserted into the notches. The two ends of the pivot 142 are respectively mounted within the L-shaped notches of the two hooks 141, forming a detachable structure.

[0048] Multiple rotating slats 143 can be hinged side-by-side to a rotating shaft 142 and can swing around the shaft 142 to separate overlapping materials. The rotating slats 143 can be plate-like structures, generally rectangular, and can be 15-20 in number. The multiple rotating slats 143 can be arranged side-by-side along the axial direction of the rotating shaft 142, with each slat 143 having a central hole that hinges to the shaft 142, forming a structure that can independently swing around the shaft 142. The overall arrangement can cover the width of the conveying channel of the second conveying mechanism 120, ensuring no material is missed during passage, and that the bottom of the slats can contact the material. When the stacked material moves with the conveyor belt to below the slats, the upper layer of material contacts the bottom of the slats 143, pushing the slats 143 upwards around the shaft 142. Using the weight of the slats 143 and their swing inertia, the upper layer of material is pushed forward in the conveying direction; simultaneously, the lower layer of material can pass smoothly, ultimately separating the overlapping material into a single layer. In addition, densely arranged curtains can help block rays.

[0049] The second steel curtain assembly 150 has a similar structure and connection relationship to the first steel curtain assembly 140, and can be installed simultaneously with the first steel curtain assembly 140 or separately.

[0050] In this embodiment, the first steel curtain assembly 140 and the second steel curtain assembly 150 are equipped with hooks 141, a rotating shaft 142, and rotating slats 143. The hooks 141, with their plate-like structure and L-shaped notches, are securely connected to the cover plate 133 via bolts, ensuring overall installation rigidity and providing a detachable support point for the rotating shaft 142. The rotating shaft 142 stably supports multiple rotating slats 143 and provides a fulcrum for the slats 143 to swing. Multiple rectangular rotating slats 143 are arranged axially along the rotating shaft, and their independent hinged design allows for adaptive swinging according to the material stacking height. When upper-layer material pushes the slats upward, the slats, using their own weight and inertia, push them forward, allowing lower-layer material to pass smoothly and eliminating blind spots in the detection. Overall, this assembly ensures that material enters the detection area in a single layer, improving detection accuracy while simultaneously increasing sorting output and achieving high economic benefits.

[0051] In some embodiments, such as Figures 3 to 5 As shown, the rotating shaft 142 may further include two limiting grooves 144, which can be respectively disposed at both ends of the rotating shaft 142 and cooperate with the notches of the hook 141 to prevent the rotating shaft 142 from moving axially. The limiting grooves 144 can be disposed at both ends of the rotating shaft 142, and can be integrally formed with the rotating shaft 142 or disposed separately. The overall structure is a cylindrical ring structure, which is sleeved on both ends of the rotating shaft 142. The outer side of the ring structure has a groove that can cooperate with the L-shaped notch of the hook 141. When the equipment is running, the rotating slats 143 will generate a lateral thrust when subjected to the force of the material. The limiting grooves 144, by engaging with the notches of the hooks, can counteract these lateral forces, fix the rotating shaft 142 in a preset position, prevent it from moving left or right along the axial direction, and thus ensure the stability of the arrangement of multiple rotating slats 143.

[0052] In this embodiment of the present disclosure, by setting two limiting grooves 144, the axial movement of the rotating shaft 142 can be prevented. After the axial displacement of the rotating shaft 142 is restricted, the rotating slats 143 can always be neatly arranged along the width of the transmission channel, avoiding the occurrence of covering gaps or overlaps due to slat offset. This ensures that the stacked materials can be effectively separated by the slats, which can effectively improve the identification accuracy and sorting accuracy, reduce the probability of missed detection and false detection, ensure the continuity of material transmission to maintain processing efficiency, and improve the reliability of detection by optimizing the material state.

[0053] In some embodiments, such as Figures 3 to 5 As shown, the rotating shaft 142 may also include a rotating handle 145 and a limiting member 146.

[0054] A rotating handle 145 is rotatably connected to the end of a rotating shaft 142, and the rotating handle 145 can rotate radially relative to the rotating shaft 142. The rotating handle 145 can be made of the same high-strength stainless steel as the rotating shaft 142. It can be cylindrical in shape and located at the end of the rotating shaft 142, allowing it to rotate radially relative to the shaft. When the steel curtain assembly needs cleaning or maintenance, the operator can extend the rotating handle 145, which can be used as an extension handle to pull upwards or move the rotating shaft 142 laterally, providing convenience and speed. When the equipment is running, the handle can be rotated back to a position perpendicular to the rotating shaft 142.

[0055] The limiting member 146 can be fixedly installed at both ends of the rotating shaft 142 to fix the rotating handle 145. The limiting member 146 can be a ring-shaped structure, fixed at both ends of the rotating shaft 142, and located on the outside of the rotating handle 145. When the steel curtain assembly needs cleaning or maintenance, the rotating handle 145 can be rotated to a certain position, and the limiting member 146 can fix the rotating handle 145 by bolts, clips, etc. When the equipment is running, the limiting member 146 can also fix the rotating handle 145.

[0056] In this embodiment, the rotary handle 145 is made of high-strength stainless steel to suit industrial environments. Its radial rotation around the shaft facilitates disassembly. During maintenance and cleaning, the handle can be extended as a point of force application, significantly shortening disassembly and assembly time and reducing equipment downtime maintenance costs. When the equipment is running, the handle can be rotated back to a position perpendicular to the shaft, without occupying extra space or interfering with material transmission or the swing separation of the rotating curtain 143, thus balancing ease of operation and operational compatibility. The limiting component 146 forms a reliable constraint on the outside of the handle through a ring structure and fixing methods such as bolts and buckles. During maintenance, the handle can be fixed in a position that facilitates force application, preventing the handle from shaking during operation and affecting disassembly and assembly efficiency. When the equipment is running, the handle is stably fixed to prevent it from shifting or falling off due to conveyor belt vibration or material impact, eliminating the risk of equipment failure caused by loose parts, and realizing the high-frequency maintenance and safety requirements of continuous industrial production.

[0057] In some embodiments, such as Figure 1 , Figure 2 , Figure 6 As shown, the first transmission mechanism 110 may include: a first belt conveyor mechanism 111, two side guards 112 and one or more partition baffles 113.

[0058] The first belt conveyor mechanism 111 is used to convey materials. The first belt conveyor mechanism 111 can rely on stable belt drive to ensure that materials can be continuously and smoothly conveyed to the second transmission mechanism 120, avoiding material accumulation caused by unstable conveying, and providing orderly initial conditions for subsequent speed difference separation and detection.

[0059] The two side guards 112 can be arranged on both sides of the first belt conveyor 111 along the conveying direction of the first belt conveyor 111. The two side guards 112 can be arranged to fit against both sides of the belt along the conveying direction, which can effectively prevent the material from moving to both sides during transmission, prevent the material from falling or deviating from the conveying path, and ensure the integrity of the material conveying.

[0060] One or more partition baffles 113 can be arranged above the first belt conveyor 111 along the conveying direction of the first belt conveyor 111. The side guards 112 and the partition baffles 113 together form multiple material conveying channels, allowing materials to be transported along these channels to the second conveying mechanism 120. The partition baffles 113 can be plate-shaped structures, arranged above the first belt conveyor 111. When multiple baffles are provided, the spacing between adjacent baffles can be adjusted according to the material size, ensuring that each channel accommodates only a single row of material. The partition baffles 113 can divide the conveying surface of the first belt conveyor 111 into two or more independent material conveying channels, enabling parallel material transport across multiple channels. Furthermore, the partition baffles 113 can prevent lateral movement of materials due to vibration and inertia during belt operation, preventing material collisions and stacking across channels, ensuring that materials within a single channel are transported along a fixed path. The detection mechanism 130 can simultaneously detect materials in multiple material conveying channels, improving detection efficiency and output. Furthermore, the number of sorting devices 200 can be set to match the number of material conveying channels, allowing multiple sorting devices 200 to sort materials simultaneously, thereby improving sorting efficiency and further increasing the sorting output of materials.

[0061] In this embodiment of the disclosure, by setting one or more partition baffles 113, the multi-channel parallel design increases the material throughput of the first transmission mechanism 110 by two times or more. The detection mechanism 130 can detect and identify the material at the same time, and the subsequent sorting device can sort the material at the same time, further improving the material sorting output. The sorting output increases exponentially, resulting in high economic benefits.

[0062] Based on the same inventive concept, exemplary embodiments of this disclosure also provide a sorting machine, such as... Figure 1 , Figure 2 , Figure 10 As shown, it can be used for material sorting, including: identification device 100 and sorting device 200 as described in the foregoing embodiments.

[0063] like Figure 1 , Figure 2As shown, the identification device 100 is used to convey and separate materials, and the detection mechanism 130 in the identification device 100 can detect the category of the materials. The second transmission mechanism 120 in the identification device 100 is set at a higher speed than the first transmission mechanism 110, which can create a speed difference when the continuously conveyed materials enter the downstream, effectively widening the gap between the front and rear materials and avoiding detection blind spots caused by materials being too close together. The first steel curtain assembly 140 separates the stacked materials upstream of the detection mechanism 130, avoiding the occlusion problem caused by material overlap and ensuring that each material can enter the detection area in an independent state. The two work together to enable the detection mechanism 130 to detect materials more clearly and comprehensively, effectively improving the identification accuracy and sorting accuracy, reducing the probability of missed detection and false detection, ensuring the continuity of material transmission to maintain processing efficiency, and improving detection reliability by optimizing the material state, thus improving the overall practicality of the equipment and achieving high economic benefits.

[0064] The sorting device can be installed at the discharge end of the identification device 100 to sort materials according to the detection results of the detection mechanism 130. The sorting device can be installed downstream of the second transmission mechanism 120. The sorting device 200 can sort materials according to their categories, so that materials of different categories can be separated from each other.

[0065] In this embodiment, a sorting machine can be configured, including an identification device 100 and a sorting device 200, to sort materials. The identification device 100 includes a first transmission mechanism 110, a second transmission mechanism 120, a detection mechanism 130, and a first steel curtain assembly 140. The speed difference between the second transmission mechanism 120 and the first transmission mechanism 110 automatically widens the gap between closely packed materials. Combined with the separation effect of the first steel curtain assembly 140 on stacked materials, the materials enter the detection area in a single layer and independently, completely eliminating the detection blind spots caused by overlapping and close proximity of materials in traditional devices. The detection mechanism 130, through the vertical arrangement of the X-ray source and receiving device, uses the density difference between materials and foreign objects for identification. The state of the materials after double separation significantly improves the clarity of X-ray detection, significantly reduces the rate of missed and false detections, and ensures sorting accuracy. Furthermore, the detachable design of the first steel curtain assembly 140 facilitates cleaning and maintenance, reducing equipment downtime. Overall, the device balances processing efficiency, detection accuracy, and ease of maintenance. It effectively improves identification and sorting accuracy, reduces material overlap that could lead to inaccurate identification and sorting, and increases the reliability and economic benefits of the setup.

[0066] In some embodiments, such as Figure 1 , Figure 2 , Figure 9 As shown, the sorting device 200 may include: a receiving belt 210, a sorting belt 220, and a drive device 230.

[0067] The receiving belt 210 can be located downstream of the second conveying mechanism 120 to receive and transport the material discharged from the second conveying mechanism 120. The receiving belt 210 can be located downstream of the second conveying mechanism 120, and its width can be consistent with the output end of the second conveying mechanism 120. The input end of the receiving belt 210 is connected to the second conveying mechanism 120, allowing it to receive and transport materials. The speed of the receiving belt 210 can also be consistent with that of the second conveying mechanism 120, ensuring continuous transmission, providing a stable foundation for downstream sorting or collection, and supporting the efficient operation of the device.

[0068] The sorting belt 220 has one end for receiving material from the belt 210 and the other end for discharging material. The number of sorting belts 220 can be consistent with the number of conveying channels in the first conveying mechanism 110, and can be two, three, or more. Multiple sorting belts 220 are arranged side by side at intervals to perform sorting operations.

[0069] The drive unit 230 can be connected to the sorting belt 220 to drive the sorting belt 220 to rotate, so that the material is sorted to different positions. When the material reaches the sorting device 200, the drive unit 230 controls its own action according to the instruction of the identification signal, thereby sorting the material. The drive unit 230 can be a cylinder or the like, and can be connected one-to-one with the sorting belt 220 to achieve independent sorting for each section of the sorting belt. By driving the sorting belt 220 to rotate, the inclination direction of the belt's discharge end relative to the feed end can be changed, so that the material changes from horizontal conveying to inclined sliding, and then falls into different collection devices, thus achieving material sorting.

[0070] In this embodiment, the sorting device 200 achieves efficient material reception and precise sorting through the coordinated arrangement of the receiving belt 210, the sorting belt 220, and the driving device 230, resulting in significant technical benefits. The receiving belt 210 and the second transmission mechanism 120 have the same width and synchronized speed, ensuring stable material reception and preventing material drop or accumulation during transfer, thus guaranteeing continuous transmission and laying a stable foundation for subsequent sorting. The number of sorting belts 220 matches the conveying channels of the first transmission mechanism 110, and they are arranged side-by-side at intervals, allowing them to receive materials from different channels and preventing material mixing during sorting. The driving device 230 corresponds one-to-one with the sorting belts 220, independently driving the belts to rotate and changing the tilt direction of the discharge end, causing the material to change from horizontal conveying to inclined sliding, accurately falling into different collection devices. This achieves efficient material sorting based on detection results and, through independent driving, adapts to the needs of multi-channel parallel processing, improving sorting efficiency and comprehensively meeting the precise sorting and efficient operation requirements of continuous industrial production.

[0071] In some embodiments, such as Figure 1 , Figure 10 , Figure 11 As shown, the sorting machine may further include a collection device 300 for collecting materials of different categories after being sorted by the sorting device 200. The collection device 300 can be a belt 310 or a collection box 320. Two or more collection devices 300 can be provided, depending on the number of categories to be sorted. The collection device 300 is used to receive different materials after being sorted by the sorting device 200, and can collect and temporarily store materials in categories. In this embodiment, by setting up collection devices 300, and providing two or more independent devices according to the sorting categories, the mixing of different categories of materials can be completely avoided through continuous belt receiving or independent storage in the boxes. The belt 310 is suitable for high-frequency continuous production and can automatically transfer materials, reducing manual intervention; the collection box 320 facilitates temporary storage of materials, preventing congestion in the sorting device due to untimely downstream transfer, ensuring continuous operation of the entire machine, and improving material sorting efficiency and production process stability.

[0072] In some embodiments, such as Figure 11 As shown, the collection device 300 may include: multi-layer belts 310, arranged vertically, for receiving different types of materials and discharging them. The belts 310 may have two or more layers, depending on the number of types to be sorted. The entire assembly can be vertically stacked, with each layer being an independent belt conveyor unit. According to the sorting results, different categories of materials (such as qualified materials and materials containing foreign matter) fall into their corresponding belt layers. Through independent conveying of each layer, the materials are continuously transported to downstream designated areas (such as sorting silos or packaging stations), preventing mixing of different types of materials, greatly reducing worker workload, and improving production line efficiency.

[0073] In some embodiments, such as Figure 1 , Figure 2As shown, the materials to be sorted first enter the first conveying mechanism 110. Its side baffles 112 and separating baffles 113 can form multiple independent conveying channels, restricting the lateral movement of the materials and ensuring that the materials are conveyed smoothly along fixed channels, avoiding collisions across channels. At the same time, it provides a precise pre-positioning basis for subsequent detection and sorting. The materials enter the second conveying mechanism 120 from the output end of the first conveying mechanism 110 (aligned with the input end of the second conveying mechanism 120). Because the speed of the second conveying mechanism is higher than that of the first conveying mechanism 110, after the materials that are close together enter, the materials in front accelerate quickly while the materials behind lag behind, and a gap is automatically formed between the two, realizing the initial separation of the materials. The materials move with the first conveying mechanism 110 to the first steel curtain assembly 140 upstream. When the stacked materials contact the bottom end of the rotating curtain 143, the upper layer of materials pushes the curtain to swing upward around the rotating shaft 142. The curtain uses its own weight and inertia to push the upper layer of materials forward, and the lower layer of materials passes smoothly. Finally, all materials continue to be conveyed in a single layer, eliminating the detection blind spot. Single-layer material enters the detection mechanism 130. The cover plate 133 and the first and second steel curtain assemblies form a closed protective space (to prevent radiation leakage). The top radiation source 131 emits radiation that penetrates the material. The radiation receiving device 132 below can capture changes in radiation intensity based on the density difference between the material and foreign objects, determine whether the material is qualified, and transmit the detection signal to the sorting device 200 in real time. After detection, the material enters the receiving belt 210 of the sorting device 200. The speed of the receiving belt is consistent with that of the second transmission mechanism 120 to ensure that the material is transferred without impact. Then, the material enters the sorting belt 220 (the quantity matches the channel of the first transmission mechanism 110). The drive device 230 (cylinder) independently drives the corresponding sorting belt to flip according to the detection signal, changing the tilt direction of the discharge end and guiding qualified and unqualified materials to different trajectories. Different types of materials finally fall into the collection device 300. If it is a multi-layer belt 310 (vertical layout), the materials fall into different layers of the belt according to the detection category and are transferred to the downstream silo through independent transmission. If it is a collection box 320, the materials are temporarily stored, completing the entire sorting operation.
