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.

[0018] Please see Figures 1 to 14 The present invention provides a technical solution: a supply chain logistics conveying device, including a conveyor belt 1, a transport frame base 2 provided on the surface of the conveyor belt 1, a moving stabilizing mechanism 3 provided on both sides of the transport frame base 2 for stabilizing the transport frame base 2, a covering mechanism 4 rotatably connected to both sides of the transport frame base 2 for stabilizing the object during movement, an inclined transport mechanism 5 installed inside the transport frame base 2 for smoothly transporting the object into the carriage, and a drive groove 6 fixedly connected to both sides of the conveyor belt 1 for driving the mechanism inside the transport frame base 2.

[0019] The mobile stabilizing mechanism 3 includes a fixed frame 31, which is fixedly connected to the side of the transport frame base 2. A U-shaped sliding rod 32 is slidably connected inside the fixed frame 31. A telescopic spring 33 is provided between the U-shaped sliding rod 32 and the fixed frame 31. A semi-circular locking block 34 is fixedly connected inside the U-shaped sliding rod 32. A spring locking rod 35 is slidably connected inside the fixed frame 31. A semi-circular groove that mates with the semi-circular locking block 34 is opened on the back of the spring locking rod 35. A knob 36 is rotatably connected to the side of the fixed frame 31. A lever 37 is fixedly connected to one end of the output shaft of the knob 36. The lever 37 is located at the L-shaped angle inside the spring locking rod 35.

[0020] The covering mechanism 4 includes a baffle 41, which is rotatably connected to the side of the fixed frame 31. An annular groove 42 is fixedly connected to the surface of the fixed frame 31. A rotating rod 43 is rotatably connected inside the annular groove 42. A small gear 44 is fixedly connected to the bottom of the rotating rod 43. A diagonal rod 45 is rotatably fixedly connected to the diagonal rod 45. A connecting rod 46 is hinged to one end of the diagonal rod 45, and a sliding sleeve 47 is hinged to one end of the connecting rod 46. The baffle 41 rotates from an open state to a closed state, thereby forming a enclosure structure on the side of the transport tray 58, reliably covering and constraining the objects on the transport tray 58. Within the carrying area, to prevent the object from falling off or shifting due to vibration or inertia during subsequent transport, the sliding sleeve 47 is slidably connected to the surface of the annular groove 42. A rotating rod 48 is rotatably connected to the surface of the sliding sleeve 47. One end of the rotating rod 48 is rotatably connected to the baffle 41. Through the upward sliding stroke of the sliding sleeve 47 (90 degrees), the baffle 41 is driven to rotate from the open state to the closed state, thereby forming a enclosure structure on the side of the transport tray 58, reliably covering and constraining the object on the transport tray 58 within the carrying area of ​​the transport tray 58, preventing it from falling off or shifting due to vibration or inertia during subsequent transport.

[0021] The tilting transport mechanism 5 includes a rotating shaft 51, with a gear 52 fixedly connected to one end of the rotating shaft 51 and a turntable 53 fixedly connected to the other end. The two turntables 53 are connected by a connecting rod 54, which is eccentrically connected to the turntables 53. A parallel rod 55 is rotatably connected to one end of the connecting rod 54, and the bottom of the parallel rod 55 is rotatably connected to the transport frame base 2. A second parallel rod 56 is rotatably connected to the surface of the transport frame base 2, and a fixed plate is hinged to the upper end of the parallel rod 55 and the second parallel rod 56. 57. A transport tray 58 is fixedly connected to the surface of the fixed plate 57. Through the swing of the parallel rod 55, the movement of the fixed plate 57 is precisely converted into the translational movement of the fixed plate 57. Its movement trajectory is an arc with the bottom hinge point as the center, thereby realizing the lifting and lowering of the fixed plate 57 at a constant posture, either diagonally upward or diagonally downward. Driven by the parallelogram mechanism, the fixed plate 57 moves upward and toward the interior of the carriage, smoothly lifting and transferring the transport tray 58 and objects located on it, saving manpower and improving work efficiency.

[0022] The drive groove 6 includes a sliding rail 61, which is fixedly connected to both sides of the conveyor belt 1. The guide component at the bottom of the transport frame base 2 and the sliding rail 61 fixedly installed on the frame form a sliding pair. This sliding pair constitutes a guide and limiting mechanism, which can effectively constrain the degree of freedom of the transport frame base 2 and the transport tray 58 during the transport process. The sliding rail 61 has a groove 62 inside and a slot 63 on its surface. One end of the sliding rail 61 is fixedly connected to a trigger plate 64. The groove 62 has teeth 65 fixedly connected inside. There are two sets of teeth 65 in the groove 62. The sliding rail 61 has a toothed plate 7 fixedly connected inside. When the lower end of the spring clip 35 is engaged in the slot 63, the transport frame base 2 is essentially rigidly connected or interlocked with the ground or a fixed frame through the clip. This locking mechanism greatly enhances the rigidity and stability of the entire device at the end of the conveying process, effectively suppressing any shaking or displacement that may be caused by equipment vibration or external interference, and providing an extremely stable reference platform for subsequent lifting, loading and unloading operations.

[0023] When the transport rack base 2 is in motion, it drives the pinion 44 to mesh with the toothed gear 65. The transport rack base 2 also drives the gear 52 to mesh with the toothed plate 7. When the transport rack base 2 is in motion, the U-shaped sliding rod 32 is pressed by the trigger plate 64, causing the spring latch 35 to engage in the slot 63. The fixing plate 57 accurately delivers the object to the predetermined position inside the carriage, completing the automated loading operation. Subsequently, when the mechanism reverses its movement, the fixing plate 57 can return to its initial position empty, ready for the next cycle. Simultaneously, the operator can remove the unloaded transport tray 58 from the unlocked transport rack base 2 and replace it with a transport tray 58 loaded with the next object to be transported, thus preparing to begin a new round of automated conveying and loading / unloading cycles.

[0024] The method of use and advantages of this invention: The working process of this supply chain logistics conveying device is as follows: like Figures 1 to 14 As shown.

[0025] In use, large objects to be transported are first placed on the surface of the transport tray 58, and then transported via the conveyor belt 1. During the transport process, the guide component fixedly connected to the bottom of the transport frame base 2 and the sliding rail 61 fixedly installed on the frame form a sliding pair. This sliding pair constitutes a guide and limiting mechanism, which can effectively constrain the degrees of freedom of the transport frame base 2 and the transport tray 58 during the transport process, preventing lateral deviation or overturning, and ensuring the stability and reliability of the transport process. Simultaneously, the pinion 44, which moves with the transport frame base 2, is embedded in the groove 62 under the guidance of the guide, and moves with the transport... As the process progresses, the pinion 44, guided by the slide groove 62, gradually engages with the first set of teeth 65 fixed on the frame. Since the first set of teeth 65 is stationary while the transport frame base 2 continues to advance, the meshing action between the pinion 44 and the first set of teeth 65 converts the horizontal linear motion of the transport frame base 2 into the rotational motion of the pinion 44 around its own axis. The pinion 44 drives the rotating rod 43 to rotate via a key connection or coaxial fixation. The rotational motion of the rotating rod 43 is then converted into the circular motion of the inclined rod 45. When the inclined rod 45 is making circular motion, its distal end is hinged to one end of the connecting rod 46. The other end of the connecting rod 46 is hinged to a sliding sleeve 47 located outside the rotating rod 43. The motion of the inclined rod 45 is transmitted to the sliding sleeve 47 through the connecting rod 46, forcing the sliding sleeve 47 to slide along the inner surface of a fixed annular slide groove 42. The trajectory of the annular groove 42 is configured to convert and limit the continuous rotational motion of the inclined rod 45 into a precise 90-degree arc lifting and sliding stroke of the sleeve 47 along the annular groove 42. The outer wall of the sleeve 47 is hinged to one end of a rotating rod 48, and the other end of the rotating rod 48 is hinged to a baffle 41. The baffle 41 is rotatably mounted on the fixed frame 31 via a pivot. The sliding of the sleeve 47 is further converted into the rotational motion of the baffle 41 about its pivot through the transmission of the rotating rod 48. Specifically, the upward sliding stroke of the sleeve 47 by ninety degrees drives the baffle 41 to rotate from the open state to the closed state, thereby forming a enclosure structure on the side of the transport tray 58, reliably covering and constraining the objects on the transport tray 58 within the bearing area of ​​the transport tray 58, preventing them from falling off or shifting due to vibration or inertia during subsequent transport. Then, the pinion 44 will disengage from the first set of teeth 65, and the sleeve 47 on the connecting rod 46 will be supported by the inclined rod 45. When the pinion 44 re-engages with the second set of teeth 65, the inclined rod 45 rotates again, pulling the connecting rod 46 to cause the sleeve 47 to slide downward by ninety degrees, opening the transport tray 58.

[0026] Synchronously with the conveying process of the transport tray 58, the transport frame base 2 drives the rotating shaft 51 and its coaxially fixed driven gear 52 to move along the conveying path. When the transport tray 58 gradually moves to the predetermined position corresponding to the loading and unloading station, the driven gear 52 meshes with a toothed plate 7 fixedly installed on the frame or foundation. After the gear 52 meshes with the stationary toothed plate 7, the continuous forward movement of the transport tray 58 forces the driven gear 52 to rotate around its own axis. The rotation of the driven gear 52 drives the rotating shaft 51 fixedly connected to it to rotate synchronously. A turntable 53 is fixedly installed on the rotating shaft 51, thereby transmitting the rotational motion to the turntable 53. On the surface of the turntable 53, away from its center of rotation, there is an eccentric pin. One end of a connecting rod 54 is hinged to the eccentric pin through a first rotating joint. The uniform circular motion of the turntable 53 is converted into the planar motion of the connecting rod 54 through the eccentric pin. The other end of connecting rod 54 is hinged to the middle or upper part of parallel rod 55 via a second revolute joint, thereby pushing parallel rod 55 to swing around its fixed hinge point at the bottom. The bottom end of parallel rod 55 is hinged to the frame via a third revolute joint, allowing it to pivot around this hinge point. The upper middle or top part of parallel rod 55 is hinged to fixed plate 57. Therefore, the swinging motion of parallel rod 55 is directly converted into a pushing and pulling action on fixed plate 57, causing fixed plate 57 to displace. To ensure that fixed plate 57 maintains a specific horizontal state during movement, parallel rod 56 is of equal length to parallel rod 55 and arranged parallel to it. Its bottom end is also hinged to the frame via a fourth revolute joint, and its top end is hinged to fixed plate 57. Parallel rod 55, parallel rod 56, fixed plate 57, and frame together constitute a parallelogram mechanism. This mechanism precisely converts the swing of the parallel rod 55 into the translational motion of the fixed plate 57. Its trajectory is an arc centered at the bottom hinge point, allowing the fixed plate 57 to rise and fall diagonally upwards or downwards with a constant posture. Driven by the parallelogram mechanism, the fixed plate 57 moves upwards and towards the interior of the carriage, smoothly lifting and transferring the transport tray 58 and objects located on it. When it reaches the end of its travel, the fixed plate 57 accurately delivers the objects to the predetermined position inside the carriage, completing the automated loading operation. Subsequently, when the mechanism reverses its movement, the fixed plate 57 can return to its initial position empty, ready for the next cycle.

[0027] Synchronously with the conveying process of the transport tray 58, a trigger plate 64, fixedly installed on the transport frame base 2 or the transport tray 58, moves along with it. When it moves to the locking position, the trigger plate 64 contacts the inclined surface or end of a U-shaped sliding rod 32 slidably disposed on the fixed frame 31 and presses it, forcing the U-shaped sliding rod 32 to move away from the trigger plate 64. The U-shaped sliding rod 32 is installed in the guide hole or guide groove of the fixed frame 31 through a sliding pair to ensure that it slides along a predetermined straight trajectory. The U-shaped sliding rod 32 is fixedly connected to or integrally formed with a semi-circular locking block 34. The linear movement of the U-shaped sliding rod 32 directly drives the semi-circular locking block 34 to move synchronously. The movement of the semi-circular locking block 34 causes its original locking recess or plane to move away from the end of a spring locking rod 35, thereby releasing the radial constraint on the spring locking rod 35, that is, the two separate from each other and disengage from the locking state. The spring locking rod 35 typically includes a rod body, a compression spring, and a guide portion. Once the constraint at its top is removed, the spring lever 35, driven by the elastic potential energy released by the pre-compressed spring inside, moves rapidly downwards along its guide section, generating a "launching" action. Its lower end reliably embeds and locks into the pre-set slot 63 on the ground or frame. Since the spring lever 35 is connected to the transport frame base 2 via the fixing bracket 31, when the lower end of the spring lever 35 engages in the slot 63, it essentially rigidly connects or interlocks the transport frame base 2 to the ground or a fixed frame through the lever body. This locking mechanism greatly enhances the rigidity and stability of the entire device at the end of the transport process, effectively suppressing any shaking or displacement that may be caused by equipment vibration or external interference. It provides an extremely stable reference platform for subsequent lifting, loading, and unloading operations. After loading is completed, a reset operation is required. The knob 36 is manually turned, which drives the coaxial lever 37 to rotate via a keyed connection or threaded engagement. During rotation, the protrusion or end of the lever 37 contacts the top or side of the spring-loaded lever 35, applying an upward force to overcome the preload of the internal spring and forcing the spring-loaded lever 35 to retract upward. The knob 36 is continued to be turned until the top of the spring-loaded lever 35 is completely disengaged from the slot 63 and moves upward to its highest point of travel. At this point, the U-shaped sliding rod 32 returns to its initial position under the action of its own return spring, causing the semi-circular locking block 34 to reset. The locking jaws of the semi-circular locking block 34 realign and lock the top of the spring-loaded lever 35, holding it stably in the retracted state. At this point, the entire locking mechanism is completely released and returned to the initial state to be triggered. The operator can then remove the unloaded transport tray 58 from the unlocked transport rack base 2 and replace it with the transport tray 58 loaded with the next item to be transported, thus preparing to start a new round of automated conveying and loading / unloading cycle.
