[0004] The cross-belt sorting mechanism in the above invention has poor support and guiding performance during use, and is prone to shaking and deviation, which affects the use of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a cross-system, mixed-use, circular, cross-belt sorting system to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cross-mechanism mixed collection and delivery ring-shaped cross-belt sorting system, including a sorting device, the sorting device consisting of a holding platform, a worktable, and a transmission mechanism. The transmission mechanism is installed on the upper side of the worktable and consists of a frame, a shaft, a conveyor belt, and a first motor. The frame is installed on both sides of the holding platform, the shaft is rotatably installed on both sides of the frame, one end of the shaft passes through the frame and is installed at the front end of the first motor, the first motor is installed on one side of the frame, the conveyor belt wraps around the outside of the shaft, the bottom end of the holding platform is installed on the upper side of the mounting platform, a guide mechanism is installed between the bottom end of the mounting platform and the worktable, a support mechanism is installed between the holding platform and the worktable, one side of the mounting platform is installed on one side of the transmission mechanism, the bottom end of the transmission mechanism is installed on the upper side of the mounting frame, the mounting frame is installed around the inside of the worktable, the bottom end of the transmission mechanism is installed on the upper side of the power mechanism, and the upper end of the power mechanism is installed on the bottom end of the mounting frame.

[0007] Preferably, the guiding mechanism consists of rollers and slide rails, with the slide rails mounted on the upper side of the worktable and the rollers rotatably mounted on the bottom end of the mounting platform, and the rollers and slide rails being slidably connected.

[0008] Preferably, the transmission mechanisms are provided with flexible connectors, and the flexible connectors are fixedly installed on one side of adjacent transmission mechanisms by bolts.

[0009] Preferably, the transmission mechanism consists of a large gear disc and a chain, with the chain meshing on the upper side of the large gear disc, the bottom end of the large gear disc mounted on one side of the mounting frame, and one side of the mounting platform mounted on one side of the chain.

[0010] Preferably, the power mechanism consists of a second motor and a transmission. The transmission is mounted at the bottom of the mounting bracket, and the upper shaft of the transmission passes through the mounting bracket and is connected to the transmission mechanism. The second motor is mounted at the bottom of the transmission.

[0011] Preferably, the support mechanism consists of a support column and ball bearings. The support column is installed around the bottom of the serving table, and the ball bearings are rolled on the bottom of the support column and rolled on the upper side of the worktable.

[0012] Preferably, the conveyor belt surface is uniformly distributed with anti-slip protrusions, which are integrally molded from elastic rubber material, and the spacing between adjacent anti-slip protrusions is 2-5cm; the mounting platform and the holding platform are fixedly connected by shock-absorbing pads, which are honeycomb-structured silicone pads.

[0013] Preferably, the outer sides of the first motor and the power mechanism are provided with heat dissipation covers, the surface of which has a plurality of heat dissipation holes, and dustproof nets are installed inside the heat dissipation holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The guide mechanism at the bottom of the mounting platform ensures that it slides smoothly along a fixed trajectory, while the support mechanism further enhances the stability of the holding platform during movement, avoiding shaking caused by material conveying or position adjustment, thereby achieving synchronous coordination of material conveying and position adjustment during the sorting process, and ensuring sorting efficiency and accuracy in cross-organization mixed collection and delivery scenarios.

[0016] 2. During the straight conveying phase, the flexible connector remains taut, effectively preventing materials from falling out of the gaps between the mechanisms during transmission and ensuring conveying safety. When the system enters the turning phase, the flexible connector adapts by extending due to its own flexibility, preventing pulling or breakage due to the angle adjustment of the mechanism. This ensures the continuous operation of the conveying mechanism during the circular sorting process. At the same time, the bolt fixing method ensures the firmness of the connection and prevents loosening during long-term operation, thus balancing the continuity and stability of the transmission and adapting to the complex operating trajectory requirements of cross-mechanism circular sorting.

[0017] 3. After the power output from the power mechanism is transmitted to the large gear plate, the large gear plate and the chain form a meshing transmission. Since one side of the mounting platform is fixedly connected to the chain, the cyclical movement of the chain can drive the mounting platform to move synchronously, thereby realizing the overall displacement of the holding platform and the upper transmission mechanism. The meshing transmission between the large gear plate and the chain has the advantages of stable transmission ratio and high power transmission efficiency, which can ensure that the movement speed and displacement accuracy of the mounting platform are controllable, and adapt to the precise docking requirements of different sorting stations in cross-mechanism mixed receiving and sending scenarios.

[0018] 4. The support mechanism provides multi-point stable support for the holding platform through the rolling cooperation of the support column and the ball bearings, while adapting to the movement requirements of the holding platform. When the holding platform moves under the drive of the transmission mechanism, the ball bearings at the bottom of the support column roll along the upper side of the worktable, which can provide uniform support force for the holding platform, distribute the weight of the holding platform and the materials, and prevent the holding platform from deforming due to excessive local stress. At the same time, the ball bearings can roll synchronously with the movement of the holding platform without generating resistance to the movement. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the invention, the cross-mechanism mixed collection and delivery ring cross-belt sorting system includes a sorting device 1. The sorting device 1 consists of a holding platform 2, a workbench 4, and a transmission mechanism 10. The transmission mechanism 10 is installed on the upper side of the workbench 4 and consists of a frame 11, a shaft 9, a conveyor belt 6, and a first motor 8. The frame 11 is installed on both sides of the holding platform 2, and the shaft 9 is rotatably installed on both sides of the frame 11. One end of the shaft 9 passes through the frame 11 and is installed at the front end of the first motor 8. The first motor 8 is installed on one side of the frame 11. The conveyor belt 6 wraps around the outside of the shaft 9. The bottom end of the holding platform 2 is installed on the upper side of the mounting platform 23. A guide mechanism 3 is installed between the bottom end of the mounting platform 23 and the workbench 4. A support mechanism 14 is installed between the holding platform 2 and the workbench 4. One side of the mounting platform 23 is installed on one side of the transmission mechanism 5. The bottom end of the transmission mechanism 5 is installed on the upper side of the mounting frame 22. The mounting frame 22 is installed around the inside of the workbench 4. The bottom end of the transmission mechanism 5 is installed on the upper side of the power mechanism 18, and the upper end of the power mechanism 18 is installed on the bottom end of the mounting frame 22.

[0027] The guiding mechanism 3 consists of rollers 17 and slide rails 13. The slide rails 13 are mounted on the upper side of the worktable 4, and the rollers 17 are rotatably mounted on the bottom end of the mounting platform 23. The rollers 17 and slide rails 13 are slidably connected. Through the sliding cooperation between the rollers 17 and slide rails 13, the guiding mechanism 3 provides precise guidance and smooth support for the movement of the mounting platform 23. When the transmission mechanism 5 drives the mounting platform 23 to move, the rollers 17 at the bottom of the mounting platform 23 roll along the slide rails 13 on the upper side of the worktable 4, converting the sliding friction between the mounting platform 23 and the worktable 4 into rolling friction. This significantly reduces movement resistance and component wear. Simultaneously, the limiting function of the slide rails 13 strictly constrains the movement trajectory of the mounting platform 23, preventing deviation during turns or straight-line movement in circular sorting. This ensures the movement accuracy of the holding platform 2 and the transmission mechanism 10, providing a fundamental guarantee for the stable transmission of materials across mechanisms.

[0028] Flexible connectors 7 are installed between the transmission mechanisms 10, and the flexible connectors 7 are fixed to one side of adjacent transmission mechanisms 10 by bolts. During the straight conveying phase, the flexible connectors 7 remain taut, effectively preventing materials from falling out of the gaps between the mechanisms during transmission and ensuring conveying safety. When the system enters the turning phase, the flexible connectors 7 adapt by extending due to their own flexibility, and will not be pulled or broken due to the angle adjustment of the mechanism, ensuring the continuous operation of the transmission mechanism 10 during the circular sorting process. At the same time, the bolt fixing method ensures the firmness of the connection and avoids loosening during long-term operation, taking into account both the continuity and stability of transmission, and adapting to the complex operating trajectory requirements of cross-mechanism circular sorting.

[0029] The transmission mechanism 5 consists of a large gear disc 21 and a chain 12. The chain 12 is meshed and mounted on the upper side of the large gear disc 21, and the bottom end of the large gear disc 21 is mounted on one side of the mounting frame 22. One side of the mounting platform 23 is mounted on one side of the chain 12. After the power output from the power mechanism 18 is transmitted to the large gear disc 21, the large gear disc 21 and the chain 12 form a meshing transmission. Since one side of the mounting platform 23 is fixedly connected to the chain 12, the cyclic movement of the chain 12 can drive the mounting platform 23 to move synchronously, thereby realizing the overall displacement of the holding platform 2 and the upper transmission mechanism 10. The meshing transmission between the large gear disc 21 and the chain 12 has the advantages of stable transmission ratio and high power transmission efficiency, which can ensure that the movement speed and displacement accuracy of the mounting platform 23 are controllable, adapting to the precise docking requirements of different sorting stations in cross-mechanism mixed collection and delivery scenarios.

[0030] The power mechanism 18 consists of a second motor 20 and a gearbox 19. The gearbox 19 is mounted at the bottom of the mounting frame 22, and its upper shaft passes through the mounting frame 22 and is connected to the transmission mechanism 5. The second motor 20 is mounted at the bottom of the gearbox 19. The power mechanism 18 provides a stable and controllable power output for the movement of the entire sorting device 1. The speed is adjusted through the gearbox 19 to adapt to different sorting efficiency requirements. During operation, the second motor 20 starts and outputs its initial power, which is transmitted to the gearbox 19. The gearbox 19 adjusts its output speed according to the needs of the sorting scenario, such as the conveying speed of different materials and the movement rhythm of different mechanisms. The adjusted power is transmitted to the transmission mechanism 5 through the output shaft, providing suitable power support for the operation of the transmission mechanism 5.

[0031] The support mechanism 14 consists of a support column 15 and ball bearings 16. The support column 15 is installed around the bottom of the holding platform 2, and the ball bearings 16 are rolled on the bottom of the support column 15 and the upper side of the worktable 4. Through the rolling cooperation of the support column 15 and the ball bearings 16, the support mechanism 14 provides multi-point stable support for the holding platform 2, while also adapting to the movement requirements of the holding platform 2. When the holding platform 2 moves under the drive of the transmission mechanism 5, the ball bearings 16 at the bottom of the support column 15 roll along the upper side of the worktable 4, providing uniform support force to the holding platform 2, distributing the weight of the holding platform 2 and the material, preventing deformation of the holding platform 2 due to excessive local stress, and rolling synchronously with the movement of the holding platform 2 without generating resistance to movement.

[0032] The conveyor belt 6 has uniformly distributed anti-slip protrusions on its surface. These protrusions are integrally molded from elastic rubber, with a spacing of 2-5 cm between adjacent protrusions. The mounting platform 23 and the holding platform 2 are fixedly connected by shock-absorbing pads, which are honeycomb-structured silicone pads. In cross-mechanism sorting scenarios, packages vary in size and weight. The elastic rubber anti-slip protrusions increase the friction between the conveyor belt and the bottom of the package, preventing slippage or deviation during high-speed transport, turning, or starting and stopping. This is especially effective in preventing lightweight packages and smooth-surfaced packages (such as plastic bags and cartons) from slipping, ensuring accurate sorting trajectories. The elastic material provides cushioning, absorbing the impact of package placement and reducing bounce. The reasonable spacing of 2-5 cm avoids uneven force distribution on the bottom of the package due to insufficient spacing, while also preventing reduced anti-slip effect due to excessive spacing. It also does not affect the contact and transmission between the conveyor belt and the shaft, adapting to the continuous movement requirements of circular sorting. The operation of the first motor and power mechanism, as well as the transport of packages, will generate vibrations. The porous structure of the honeycomb silicone pad can effectively absorb the vibration energy, preventing the vibration from being transmitted to the holding platform and the above transport mechanism. This prevents packages from shifting position or tilting due to vibration, ensuring the synchronous coordination of material transport and the adjustment of the mounting platform position, and improving sorting accuracy.

[0033] Both the first motor 8 and the power mechanism 18 are equipped with heat sinks on their outer sides. The heat sinks have several heat dissipation holes on their surface, and dustproof nets are installed inside the holes. The first motor drives the conveyor belt, and the power mechanism drives the transmission mechanism; both are core power sources of the system and generate a large amount of heat during prolonged operation. The heat dissipation holes on the heat sink surface create air convection, quickly dissipating heat from the generator and preventing the motor from overheating, causing unstable speed, shutdown protection, or burnout, thus ensuring continuous sorting operations. The logistics sorting center generates a lot of dust and paper scraps; the dustproof nets inside the heat dissipation holes prevent dust and impurities from entering the motor and power mechanism, avoiding dust adhesion to precision components such as bearings, coils, and gears, preventing component wear, short circuits, or transmission failures, and reducing equipment maintenance frequency and failure rate.

[0034] The working principle and usage process of this invention: The sorting device 1 achieves stable material transport through the transmission mechanism 10. Simultaneously, with the synergistic effect of the transmission mechanism 5 and the power mechanism 18, the holding platform 2 is driven to precisely shift along the worktable 4, adapting to the circular sorting requirements of cross-agency collection and delivery. During operation, the first motor 8 starts and drives the shaft 9 to rotate. The shaft 9 drives the outer conveyor belt 6 to rotate synchronously, allowing materials to be placed on the conveyor belt 6 for stable transport. The power output of the power mechanism 18 is transmitted to the transmission mechanism 5 after the speed is adjusted by the gearbox 19. The transmission mechanism 5 drives the connected mounting platform 23 to move through the meshing of the large gear 21 and the chain 12. The guide mechanism 3 at the bottom of the mounting platform 23 ensures that it slides smoothly along a fixed trajectory. The support mechanism 14 further enhances the stability of the holding platform 2 during movement, preventing shaking caused by material transport or position adjustment. This achieves synchronous coordination of material transport and position adjustment during sorting, ensuring sorting efficiency and accuracy in cross-agency mixed collection and delivery scenarios.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
