Technical Field

[0001] The utility model relates to the technical field of ore sorting equipment, in particular to a heat dissipation structure and a sorting machine. Background Art

[0002] At present, when sorting ore, optical identification devices such as X-ray machines are usually used. However, X-ray machines will generate a certain amount of heat when working. In related technologies, heat exchangers installed in the sorting machine cabinet are usually used to dissipate heat. However, since the internal space of the cabinet is relatively closed, the cooling effect on the optical identification device is poor. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] In view of this, an embodiment of the first aspect of the present invention provides a heat dissipation structure.

[0005] The embodiment of the second aspect of the utility model provides a sorting machine.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the first aspect of the utility model provides a heat dissipation structure for a sorting machine, the sorting machine includes a cabinet and an optical recognition device arranged in the cabinet, the heat dissipation structure includes: a lifting device, which is movably arranged in the cabinet, and the moving range of the lifting device includes a first station and a second station; a heat exchange device, which is arranged on the lifting device, and the heat exchange device is used to dissipate heat for the optical recognition device. When the lifting device is located at the first station, the heat exchange device is located outside the cabinet, and when the lifting device is located at the second station, the heat exchange device is located inside the cabinet; wherein, the lifting device moves from one of the first station and the second station to the other, and the movement trajectory of the heat exchange device is a straight line.

[0007] The heat dissipation structure proposed by the utility model mainly includes a lifting device and a heat exchange device. The design of the lifting device allows the heat exchange device to move between inside and outside the cabinet to meet different heat dissipation needs and transportation needs. Among them, the lifting device enables the heat exchange device to move inside and outside the cabinet according to the heat dissipation needs. When the heat dissipation device is in use, it can better absorb fresh cold air for heat exchange. When it is transported, it can be retracted into the equipment without additional disassembly of the heat dissipation device due to height restrictions. It can be understood that this solution optimizes the problem of the heat dissipation device in the overall layout of the equipment and reduces the disassembly of unnecessary components when the equipment is transported and the use status changes.

[0008] It can be understood that when the heat dissipation demand is high, the heat exchange device is moved outside the cabinet to utilize a larger ambient space for efficient heat dissipation; when low temperature is required or space is limited, it can be retracted into the cabinet.

[0009] Specifically, the lifting device allows the heat exchange device to move between designated positions (the first station and the second station) inside and outside the cabinet, ensuring that the heat exchange device can flexibly adjust its position according to working conditions and heat dissipation requirements to optimize heat dissipation efficiency. The heat exchange device is directly responsible for dissipating heat from the optical recognition device to keep it running at the optimal operating temperature. The position change of the heat exchange device enhances the heat dissipation capacity and avoids performance degradation or damage to the optical recognition device due to overheating.

[0010] It should be emphasized that in this solution, the movement trajectory of the heat exchanger is a straight line under the action of the lifting device. On the one hand, the straight line movement trajectory simplifies the structure and reduces the failure points. On the other hand, the movement of the heat exchanger is smoother, reducing the possibility of failure of the heat exchanger during movement.

[0011] In some technical solutions, optionally, the heat exchange device includes: a supporting plate fixedly connected to the lifting device, and a heat exchanger is provided on the supporting plate.

[0012] In this technical solution, the heat exchange device includes a supporting plate and a heat exchanger, wherein the supporting plate provides a stable platform to fix the heat exchanger on the lifting device, thereby ensuring a close connection between the heat exchanger and the lifting device, thereby ensuring the stability of the heat exchanger during movement, reducing potential damage caused by vibration or movement, and facilitating the heat exchanger to dissipate heat in the optimal position.

[0013] The heat exchanger is directly responsible for absorbing the heat generated by the optical recognition device and releasing it to the outside world. It is the core component for achieving the purpose of heat dissipation. With the support of the carrier plate, the heat exchanger can be accurately positioned in the area where heat dissipation is most needed. The heat exchanger set on the carrier plate can efficiently perform heat exchange. Whether working inside or outside the cabinet, it can effectively maintain the operating temperature of the optical recognition device within a safe range, thereby ensuring the stable operation of the equipment and extending its service life.

[0014] By closely combining the design of the carrier plate and the heat exchanger, this heat dissipation solution not only achieves efficient heat dissipation, but also takes into account the overall stability and reliability of the system. The introduction of the carrier plate not only provides a stable installation platform for the heat exchanger, but also makes the movement of the entire heat dissipation device more flexible and safe, providing a strong guarantee for the efficient operation of the sorting machine in different working environments.

[0015] In some technical solutions, optionally, the lifting device includes: a screw structure extending along the motion trajectory of the heat exchange device, and the telescopic end of the screw structure is fixedly connected to the heat exchange device.

[0016] In this technical solution, the lead screw structure, as the core mechanical component of the lifting device, realizes precise lifting and lowering control of the heat exchange device through its spiral linear motion characteristics. The fixed connection between the telescopic end and the heat exchange device ensures that the heat exchange device can move stably along the set straight path. It can be understood that the introduction of the lead screw structure makes the position adjustment of the heat exchange device during the lifting process more stable and precise, greatly reducing the vibration or deviation caused by movement, and ensuring the maximization of heat exchange efficiency. At the same time, the design of the lead screw mechanism also allows for detailed adjustment of the height of the heat exchange device, so that the heat dissipation system can better adapt to different transportation needs and heat dissipation needs.

[0017] Through the fixed connection between the screw structure and the heat exchange device, the lifting device not only provides the power and guidance for the movement of the heat exchange device, but also ensures the stability and reliability of the entire heat dissipation system. The use of the screw structure makes the entire heat dissipation solution not only more convenient and accurate in operation, but also more stable and reliable in structure, providing an efficient and stable heat dissipation environment for the optical recognition device, thereby ensuring the high performance and long-term stable operation of the sorting machine.

[0018] In some technical solutions, optionally, it also includes: a stabilizing guide rail, which is arranged in the cabinet, and the stabilizing guide rail extends along the movement trajectory of the heat exchange device; a matching pulley, which is arranged on the supporting plate corresponding to the stabilizing guide rail, and the matching pulley is slidably connected to the stabilizing guide rail.

[0019] In this technical solution, the addition of a stable guide rail and a matching pulley design further enhances the stability and smooth operability of the heat dissipation structure, making the entire lifting process smoother. Among them, the stable guide rail is fixed in the cabinet and is designed along the motion trajectory of the heat exchanger, providing a stable moving path for the heat exchanger. The guide rail ensures the linear motion of the heat exchanger during the lifting process, reducing lateral deviation and vibration. Guided by the stable guide rail, the movement of the heat exchanger is more stable, reducing friction and wear caused by movement, and extending the service life of the heat dissipation device. In addition, the design of the stable guide rail also ensures the precise positioning of the heat exchanger during movement, optimizing the heat dissipation effect.

[0020] The matching pulley is installed on the load plate, corresponding to the stable rail. The sliding connection between the pulley and the rail reduces the movement resistance, making the movement of the lifting device smoother and easier. The addition of the pulley system greatly reduces the friction when the heat exchange device moves, providing a smoother lifting experience. This design not only reduces noise during operation, but also reduces energy consumption, and improves the operating efficiency and reliability of the entire system.

[0021] The design of stable rails and matching pulleys makes the lifting process of the heat exchanger smoother and more stable, which not only improves the convenience of operation and the response speed of the system, but also further improves the durability and reliability of the system by reducing vibration and wear during movement. This consideration of design details ensures that the heat dissipation system can operate stably for a long time under different working environments, effectively protects the optical recognition device, and thus ensures the efficient performance and long-term stability of the sorting machine.

[0022] In some technical solutions, optionally, the bearing plate includes a connecting plate and a guiding plate that are connected to each other, the lead screw structure is fixedly connected to the connecting plate, and the matching pulley is arranged at the edge of the guiding plate.

[0023] In this technical solution, the load-bearing plate is composed of a connecting plate and a guiding plate. The connecting plate is fixedly connected to the lead screw structure, and the guiding plate is used to guide the movement of the matching pulley. By arranging the matching pulley at the edge of the guiding plate, so that it and the lead screw structure are placed at both ends of the load-bearing plate, the connecting plate plays the main load-bearing role and the lifting and lowering movement under the lead screw structure, and the guiding plate is used to achieve auxiliary support under the action of the stable guide rail and the quota and pulley, which greatly improves the lifting stability of the entire load-bearing plate.

[0024] In some technical schemes, optionally, the screw structure includes: a fixed seat, extending along the motion trajectory of the heat exchange device; a worm, arranged in the fixed seat; a worm wheel, arranged on the fixed seat, the worm wheel and the worm threaded connection; a driving wheel, connected to the worm wheel, the worm wheel rotates with the driving wheel, and the worm and the fixed seat produce relative movement.

[0025] In this technical solution, the screw structure includes a fixed seat, a worm, a worm wheel and a driving wheel, wherein the fixed seat extends along the motion trajectory of the heat exchange device to fix and support the worm and the worm wheel. The fixed seat provides support and positioning for the screw structure to ensure stable movement of the worm and the worm wheel.

[0026] The worm is located in the fixed seat and is the core component of the screw structure. The worm is connected to the worm wheel through a thread. When the worm wheel rotates, the worm moves relative to the worm, thereby driving the fixed seat and the load-bearing plate to move up and down. The drive wheel is connected to the worm wheel, and the rotation of the drive wheel drives the worm wheel to rotate. The drive wheel provides a power source, allowing the worm wheel to rotate, thereby realizing the lifting and lowering movement of the screw structure.

[0027] Among them, the driving wheel can be used as a structure for electronic intelligent control, and can also be used as a handwheel for manual adjustment by the user.

[0028] To sum up, the screw structure realizes the up and down movement of the supporting plate through the cooperation of the fixed seat, worm, worm wheel and driving wheel, thereby realizing the position adjustment of the heat exchange device and the heat dissipation effect of the optical recognition device, and improving the stability and heat dissipation efficiency of the equipment.

[0029] In some technical solutions, optionally, it also includes: a locking groove, which is arranged on the worm along the axial direction of the worm; a locking member, a part of which extends into the locking groove, and the rotation of the worm is limited by the cooperation between the locking member and the locking groove.

[0030] In this technical solution, the locking groove is arranged on the worm along the axial direction of the worm, and is an axial groove used to limit the rotation of the worm. The design of the locking groove can provide a fixed point when needed, and the rotation of the worm can be limited by extending part of the locking member into the locking groove under the cooperation of the locking member and the locking groove. It can be understood that when the locking member extends into the locking groove, the entire worm cannot rotate on its own, and the effect of parallel movement can be achieved under the action of the driving wheel. Under the drive of the hand wheel, it can only move up and down, thereby improving the stability of lifting.

[0031] In summary, the design of the locking groove and the locking piece plays a role in limiting the rotation of the worm in the screw structure, providing a safety mechanism to ensure that the worm can stay stably when it needs to be fixed in position, thereby ensuring the stable operation and working efficiency of the heat dissipation structure.

[0032] In some technical solutions, optionally, it also includes: a fastening structure, which is arranged on the carrying plate, and the fastening structure is used to connect the carrying plate to the cabinet when the lifting device is located at the first station or the second station.

[0033] In this technical solution, by providing a fastening structure, the load-bearing plate can be connected to the cabinet when the lifting device is located at the first position or the second position. Its function is to ensure that the load-bearing plate can be firmly fixed to the cabinet when it is at the two positions, so as to prevent loosening or displacement during the operation or transportation of the equipment, and ensure the safety and stability of the equipment.

[0034] It can be understood that the design of the fastening structure can effectively fix the carrier plate, so that it forms a firm connection with the cabinet, thereby ensuring the normal operation and heat dissipation effect of the heat dissipation device and the optical recognition device. The design of the fastening structure enables the carrier plate to be firmly connected to the cabinet in the first position, thereby improving the stability and reliability of the entire heat dissipation structure.

[0035] In some technical solutions, optionally, it includes: a telescopic opening, which is arranged on the top of the cabinet; and a cover plate, which is movably connected to the cabinet to open and close the telescopic opening; wherein, when the lifting device is located at the first position, the heat exchange device extends out of the telescopic opening.

[0036] In this technical solution, a telescopic opening is provided on the top of the cabinet, which is used to expand or retract when needed to facilitate the extension and retraction of the heat exchange device. The design of the telescopic opening can flexibly adjust the size according to actual needs to accommodate the telescopic movement of the heat exchange device. Among them, this solution is also provided with a cover plate, which is used to open and close the telescopic opening through a movable connection with the cabinet. The function of the cover plate is that when the lifting device is in the first position, it can be opened to allow the heat exchange device to extend out of the telescopic opening, and at the same time, the cover plate can be closed when needed to protect the heat exchange device and ensure the overall sealing of the cabinet. The movable connection between the cover plate and the cabinet includes but is not limited to a hinged connection and a sliding connection.

[0037] When the lifting device is in the first position, the heat exchange device can extend out of the telescopic opening. This design allows the heat exchange device to be moved inside and outside the cabinet as needed, facilitating the heat dissipation operation of the optical recognition device, and can be folded up when not needed to save space and protect the equipment.

[0038] The embodiment of the second aspect of the utility model provides a sorting machine, comprising: a cabinet, in which an optical recognition device is arranged; and any heat dissipation structure in the first aspect is arranged in the cabinet.

[0039] The sorting machine proposed in the utility model includes a cabinet, an optical recognition device is arranged in the cabinet, and any heat dissipation structure described in the first aspect, which is arranged in the cabinet. This design integrates the heat dissipation structure into the interior of the cabinet, and dissipates the heat of the optical recognition device through the heat dissipation structure, thereby improving the heat dissipation effect and stability of the sorting machine. By placing the heat dissipation structure inside the cabinet, the space occupied by the equipment can be effectively reduced, making the equipment layout more compact and neat. At the same time, the built-in heat dissipation structure also helps to reduce the connectors between the devices, reduce the failure rate, and improve the reliability and safety of the equipment.

[0040] It should be added that, since the sorting machine includes the heat dissipation structure of any of the above-mentioned solutions, it has the beneficial effects of any of the above-mentioned heat dissipation structures, which will not be described in detail here.

[0041] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0055] Refer to the following Figures 1 to 8 Some embodiments according to the present invention are described.

[0056] like Figure 1As shown, a heat dissipation structure 100 proposed in this embodiment mainly includes a lifting device 102 and a heat exchange device 104. The design of the lifting device 102 allows the heat exchange device 104 to move between the inside and outside of the cabinet 202 to meet different heat dissipation requirements and transportation requirements. Among them, the lifting device 102 enables the heat exchange device 104 to move inside and outside the cabinet 202 according to the heat dissipation requirements. When the heat dissipation device is in use, it can better absorb fresh cold air for heat exchange. When it is transported, it can be retracted into the equipment without additional disassembly of the heat dissipation device due to height restrictions. It can be understood that this solution optimizes the problem of the heat dissipation device in the overall layout of the equipment and reduces the disassembly of unnecessary components when the equipment is transported and the use status changes.

[0057] It is understandable that when the heat dissipation demand is high, the heat exchange device 104 is moved outside the cabinet 202 to utilize a larger ambient space for efficient heat dissipation; when low temperature is required or space is limited, it can be retracted into the cabinet 202.

[0058] Specifically, the lifting device 102 allows the heat exchange device 104 to move between designated positions (the first station and the second station) inside and outside the cabinet 202, ensuring that the heat exchange device 104 can flexibly adjust its position according to working conditions and heat dissipation requirements to optimize heat dissipation efficiency. The heat exchange device 104 is directly responsible for dissipating heat for the optical recognition device 204 to keep it running at an optimal working temperature. The position change of the heat exchange device 104 enhances the heat dissipation capacity and avoids performance degradation or damage to the optical recognition device 204 due to overheating.

[0059] When the lifting device 102 is located at the first working position, Figure 6 and Figure 8 As shown, the heat exchange device 104 is located outside the cabinet 202, and the lifting device 102 is located at the second position. Figure 5 and Figure 7 As shown, the heat exchange device 104 is located in the cabinet 202 .

[0060] It should be emphasized that in this solution, under the action of the lifting device 102, the moving trajectory of the heat exchange device 104 is a straight line. On the one hand, the straight line movement trajectory simplifies the structure and reduces the failure points. On the other hand, the movement of the heat exchange device 104 is smoother, reducing the possibility of failure of the heat exchange device 104 during movement.

[0061] In some embodiments, optionally, the heat exchange device 104 includes a supporting plate 1042 and a heat exchanger 105, wherein the supporting plate 1042 provides a stable platform to fix the heat exchanger 105 on the lifting device 102, thereby ensuring a close connection between the heat exchanger 105 and the lifting device 102, thereby ensuring the stability of the heat exchanger 105 during movement, reducing potential damage caused by vibration or movement, and facilitating the heat exchanger 105 to dissipate heat in the optimal position.

[0062] The heat exchanger 105 is directly responsible for absorbing the heat generated by the optical recognition device 204 and releasing it to the outside, and is a core component for achieving the purpose of heat dissipation. With the support of the carrier plate 1042, the heat exchanger 105 can be accurately positioned in the area where heat dissipation is most needed. The heat exchanger 105 set on the carrier plate 1042 can efficiently perform heat exchange, and can effectively maintain the operating temperature of the optical recognition device 204 within a safe range whether working inside or outside the cabinet 202, thereby ensuring the stable operation of the equipment and extending its service life.

[0063] By closely combining the design of the carrier plate 1042 and the heat exchanger 105, this heat dissipation solution not only achieves efficient heat dissipation, but also takes into account the overall stability and reliability of the system. The introduction of the carrier plate 1042 not only provides a stable installation platform for the heat exchanger 105, but also makes the movement of the entire heat dissipation device more flexible and safe, providing a strong guarantee for the efficient operation of the sorting machine 200 in different working environments.

[0064] In some embodiments, optionally, the lead screw structure 1022 serves as the core mechanical component of the lifting device 102, and realizes precise lifting and lowering control of the heat exchange device 104 through its spiral linear motion characteristics. The fixed connection between the telescopic end and the heat exchange device 104 ensures that the heat exchange device 104 can move stably along a set straight path. It can be understood that the introduction of the lead screw structure 1022 makes the position adjustment of the heat exchange device 104 during the lifting process more stable and precise, greatly reduces the vibration or deviation caused by movement, and ensures the maximization of heat exchange efficiency. At the same time, the design of the lead screw mechanism also allows for detailed adjustment of the height of the heat exchange device 104, so that the heat dissipation system can better adapt to different transportation needs and heat dissipation needs.

[0065] Through the fixed connection between the lead screw structure 1022 and the heat exchange device 104, the lifting device 102 not only provides power and guidance for the movement of the heat exchange device 104, but also ensures the stability and reliability of the entire heat dissipation system. The use of the lead screw structure 1022 makes the entire heat dissipation solution not only more convenient and accurate in operation, but also more stable and reliable in structure, providing an efficient and stable heat dissipation environment for the optical recognition device 204, thereby ensuring the high performance and long-term stable operation of the sorting machine 200.

[0066] In some embodiments, optionally, the addition of a stabilizing rail 1032 and a matching pulley 1034 further enhances the stability and smooth operability of the heat dissipation structure 100, making the entire lifting process smoother. Among them, the stabilizing rail 1032 is fixed in the cabinet 202 and is designed along the motion trajectory of the heat exchange device 104, providing a stable moving path for the heat exchange device 104. The rail ensures the linear motion of the heat exchange device 104 during the lifting process, reducing lateral deviation and vibration. Through the guidance of the stabilizing rail 1032, the movement of the heat exchange device 104 is more stable, reducing the friction and wear caused by the movement, and extending the service life of the heat dissipation device. In addition, the design of the stabilizing rail 1032 also ensures the precise positioning of the heat exchange device 104 during the movement, thereby optimizing the heat dissipation effect.

[0067] The matching pulley 1034 is mounted on the bearing plate 1042, corresponding to the stabilizing rail 1032. The sliding connection between the pulley and the rail reduces the movement resistance, making the movement of the lifting device 102 smoother and easier. The addition of the pulley system greatly reduces the friction when the heat exchange device 104 moves, providing a smoother lifting experience. This design not only reduces noise during operation, but also reduces energy consumption, and improves the operating efficiency and reliability of the entire system.

[0068] The design of the stabilizing rail 1032 and the matching pulley 1034 makes the lifting process of the heat exchange device 104 smoother and more stable, which not only improves the convenience of operation and the response speed of the system, but also further improves the durability and reliability of the system by reducing vibration and wear during movement. This consideration of design details ensures that the heat dissipation system can operate stably for a long time under different working environments, effectively protects the optical recognition device 204, and thus ensures the high efficiency performance and long-term stability of the sorting machine 200.

[0069] In some embodiments, optionally, Figure 4 As shown, the bearing plate 1042 is composed of a connecting plate 1044 and a guiding plate 1046. The connecting plate 1044 is fixedly connected to the lead screw structure 1022, and the guiding plate 1046 is used to guide the movement of the matching pulley 1034. By arranging the matching pulley 1034 at the edge of the guiding plate 1046, the matching pulley 1034 and the lead screw structure 1022 are placed at both ends of the bearing plate 1042, so that the connecting plate 1044 plays a major role in bearing the load and lifting movement under the lead screw structure 1022, and the guiding plate 1046 is used to achieve auxiliary support under the action of the stabilizing guide rail 1032 and the quota and pulley, which greatly improves the lifting stability of the entire bearing plate 1042.

[0070] In some embodiments, optionally, Figure 2As shown, the lead screw structure 1022 includes a fixed seat 1024, a worm 1026, a worm wheel 1028 and a driving wheel 1030, wherein the fixed seat 1024 extends along the motion trajectory of the heat exchange device 104, and plays a role in fixing and supporting the worm 1026 and the worm wheel 1028. The fixed seat 1024 provides support and positioning for the lead screw structure 1022, ensuring the stable movement of the worm 1026 and the worm wheel 1028.

[0071] The worm 1026 is disposed in the fixed seat 1024 and is the core component of the screw structure 1022. The worm 1026 is connected to the worm wheel 1028 by a thread. When the worm wheel 1028 rotates, the worm 1026 moves relative to each other, thereby driving the fixed seat 1024 and the carrier plate 1042 to move up and down. The driving wheel 1030 is connected to the worm wheel 1028 in a transmission manner, and the worm wheel 1028 is driven to rotate by the rotation of the driving wheel 1030. The driving wheel 1030 provides a power source, so that the worm wheel 1028 can rotate, thereby realizing the lifting and lowering movement of the screw structure 1022.

[0072] The driving wheel 1030 can be used as an electronically controlled intelligent control structure, and can also be used as a hand wheel for manual adjustment by the user.

[0073] To summarize, the screw structure 1022 realizes the up and down movement of the supporting plate 1042 through the cooperation of the fixed seat 1024, the worm 1026, the worm wheel 1028 and the driving wheel 1030, thereby realizing the position adjustment of the heat exchange device 104 and the heat dissipation effect of the optical recognition device 204, and improving the stability and heat dissipation efficiency of the equipment.

[0074] In some embodiments, optionally, Figure 3 As shown, the locking groove 1062 is provided on the worm 1026 along the axial direction of the worm 1026, and is an axial groove used to limit the rotation of the worm 1026. The design of the locking groove 1062 can provide a fixed point when needed, and by extending part of the locking member 1064 into the locking groove 1062, the rotation of the worm 1026 can be limited under the cooperation of the locking member 1064 and the locking groove 1062. It can be understood that when the locking member 1064 extends into the locking groove 1062, the entire worm 1026 cannot rotate on its own, and the effect of parallel movement can be achieved under the action of the driving wheel 1030. Under the drive of the hand wheel, it can only move up and down, thereby improving the stability of the lifting.

[0075] In summary, the design of the locking groove 1062 and the locking member 1064 plays a role in limiting the rotation of the worm 1026 in the screw structure 1022, providing a safety mechanism to ensure that the worm 1026 can stay stably when a fixed position is required, thereby ensuring the stable operation and working efficiency of the heat dissipation structure 100.

[0076] In some embodiments, optionally, Figure 7 and Figure 8 As shown, by providing the fastening structure 114, the load-bearing plate 1042 can be connected to the cabinet 202 when the lifting device 102 is located at the first position or the second position. Its function is to ensure that the load-bearing plate 1042 can be firmly fixed on the cabinet 202 when it is at the two positions, so as to prevent loosening or displacement during the operation or transportation of the equipment, and ensure the safety and stability of the equipment.

[0077] It can be understood that, through the design of the fastening structure 114, the carrier plate 1042 can be effectively fixed, so that a firm connection is formed between the carrier plate 1042 and the cabinet 202, thereby ensuring the normal operation and heat dissipation effect of the heat dissipation device and the optical recognition device 204. The design of the fastening structure 114 enables the carrier plate 1042 to be firmly connected to the cabinet 202 when in the first station or the second station, thereby improving the stability and reliability of the entire heat dissipation structure 100.

[0078] In some embodiments, optionally, a telescopic opening 110 is provided at the top of the cabinet 202, which is used to expand or retract when needed to facilitate the extension and retraction of the heat exchange device 104. The design of the telescopic opening 110 can flexibly adjust the size according to actual needs to adapt to the telescopic movement of the heat exchange device 104. Among them, the present solution is also provided with a cover plate 112, which is used to open and close the telescopic opening 110 through a movable connection with the cabinet 202. The function of the cover plate 112 is that when the lifting device 102 is located at the first station, it can be opened to allow the heat exchange device 104 to extend out of the telescopic opening 110, and at the same time, the cover plate 112 can be closed when needed to protect the heat exchange device 104 and ensure the overall sealing of the cabinet 202. The movable connection between the cover plate 112 and the cabinet 202 includes but is not limited to a hinged connection and a sliding connection.

[0079] When the lifting device 102 is at the first position, the heat exchange device 104 can extend out of the telescopic opening 110. This design allows the heat exchange device 104 to be moved inside and outside the cabinet 202 as needed, facilitating the heat dissipation operation of the optical recognition device 204, and can be folded up when not needed to save space and protect the equipment.

[0080] like Figure 4As shown, the present application proposes another embodiment of a sorting machine 200, including a cabinet 202, an optical recognition device 204 is provided in the cabinet 202, and any heat dissipation structure 100 described in the first aspect, the heat dissipation structure 100 is provided in the cabinet 202. This design integrates the heat dissipation structure 100 into the cabinet 202, and the optical recognition device 204 is dissipated by the heat dissipation structure 100, thereby improving the heat dissipation effect and stability of the sorting machine 200. By placing the heat dissipation structure 100 inside the cabinet 202, the space occupied by the equipment can be effectively reduced, making the equipment layout more compact and neat. At the same time, the built-in heat dissipation structure 100 also helps to reduce the connectors between the devices, reduce the failure rate, and improve the reliability and safety of the equipment.

[0081] It should be added that, since the sorting machine 200 includes the heat dissipation structure 100 of any of the above-mentioned solutions, it has the beneficial effects of any of the above-mentioned heat dissipation structures 100, which will not be described in detail here.

[0082] In a specific embodiment, a radiator structure (i.e., heat dissipation structure 100) is proposed, including: a radiator frame, a bottom cover plate (i.e., a bearing plate 1042), a screw structure 1022 including a screw elevator (i.e., a worm 1026, a worm wheel 1028, a driving wheel 1030), an elevator support (i.e., a fixed seat 1024), a lifting guide rail (i.e., a stabilizing guide rail 1032), etc.

[0083] The radiator frame is the outer frame of the radiator used in the optical machine. Its bottom is connected to the cover plate, and the front end is equipped with rollers. The upper end of the bottom cover plate is connected to the radiator frame, and the lower end is connected to the lead screw lift.

[0084] The screw lift is a worm gear structure. By turning the hand wheel (i.e., the driving wheel), the screw can be driven to move up and down, thereby adjusting the position of the radiator.

[0085] The lead screw is machined with an axial anti-rotation groove (i.e. locking groove), and a anti-rotation screw (i.e. locking piece) is located at the connecting plate and is stuck in the anti-rotation groove, so that the lead screw cannot rotate and can only move up and down when driven by the handwheel.

[0086] The elevator support is the fixed seat of the screw elevator. Its main body is a rectangular tube welding structure, the bottom is connected to the ground by bolts, the upper connecting plate is connected to the elevator, and there is a gap in the middle of the connecting plate to accommodate the moving screw extending downward.

[0087] The lifting rail matches the roller at the front end of the radiator frame. When the frame moves up and down under the action of the lift, the roller can also move accordingly relying on the lifting rail. The lifting rail is welded to the equipment frame and has a support plate at the bottom. When the frame moves to the bottom and is in the retracted state, the support plate can be connected and fixed to the frame to prevent the frame from moving during transportation.

[0088] In the actual use of the radiator of the sorting machine, because the radiator is large, it needs to be placed in an area with smooth air circulation when working. However, when transporting, it needs to be retracted into the equipment frame. In this embodiment, the radiator frame is arranged in the equipment frame, and there is a screw lift at its bottom, which can use the working principle of the worm gear to drive the radiator to move up and down.

[0089] When the sorting equipment is enabled, the radiator frame is inside the equipment. Its bottom is connected to the connecting plate of the screw lift. By turning the hand wheel, the screw can be driven to drive the entire frame assembly to move upward. However, the screw lift alone can only drive the frame to move a little, which is unstable. Therefore, rollers are arranged at the front end of the frame, and a guide frame is welded on the frame. When the lift moves, the rollers at the front end of the frame will also move upward along the guide frame. When it moves upward to the limit position, the bottom cover plate is attached to the upper frame, and they are connected together with bolts, and it can work normally. When the sorting equipment is transported, remove the bolts connecting the bottom cover plate and the frame, shake the hand wheel, drive the screw lift to drive the radiator frame to move downward, and the rollers at the front end of the bottom frame also move downward along the guide rail. After moving downward to the limit position, the bottom cover plate fits the support plate on the guide frame, and they are fixed together with bolts to form a stable structure, which can be transported.

[0090] The lead screw device's lead screw lever is machined with a rotation-stop groove, which is an axial rectangular notch. A rotation-stop screw is installed at the upper connecting plate, and the screw is embedded in the upper rotation-stop groove to prevent the lead screw lever from rotating. According to the principle of lead screw lifting, when the hand wheel is shaken, the lead screw lever will first rotate and not rise or fall. Only when the lead screw is controlled to rotate can the lead screw lever be raised or lowered. At the same time, when observing the side wall buckle of the support, a stop screw is installed. When the posture of the vibrating feeder has been determined and it is necessary to continuously feed in a stable state, the stop screw is screwed into the rotation-stop groove to lock the lead screw lever to prevent the lead screw support assembly from loosening due to vibration, thereby playing a safety protection role.

[0091] According to the heat dissipation structure and the sorting machine provided by the utility model, the heat exchange device is allowed to move between the inside and outside of the cabinet through the design of the lifting device to meet different heat dissipation requirements and transportation requirements.
