Description

Technical Field

[0001] The present invention relates to the technical field of logistics unloading, and in particular to a logistics unloading mechanism and method. Background Art

[0002] A logistics unloading mechanism is a key equipment for material transfer and unloading. It is widely used in industrial production, warehousing and logistics and other fields. It is mainly used to realize automatic transportation, positioning dumping and efficient unloading of materials. It can significantly improve loading and unloading efficiency, reduce labor costs and reduce material loss. Announcement No. CN212047524U discloses a free lifting device for logistics handling, which relates to the field of logistics unloading technology. The free lifting device for logistics handling includes a base plate and a placement table. The four corners of the bottom surface of the base plate are fixedly connected to rollers, one side of the base plate is fixedly connected to a trailer ring, one end of the top surface of the base plate is fixedly connected to a lifting mechanism, and the side of the placement table close to the lifting mechanism is fixedly connected to two symmetrical hooks. The free lifting device for logistics handling achieves the effect of automatic descent during loading and automatic rise during unloading by setting a lifting mechanism, a placement platform, a slide and a hook. It has the advantages of reducing the working intensity of workers and a pure mechanical structure, and does not require an external power supply. It solves the problem that in traditional logistics handling operations, the initial stage of each material discharge and the final stage of material retrieval require bending over to complete due to the low height of the discharge platform, and long-term operation will make people feel sore and tired. The invention can achieve the effect of automatic descent during loading and automatic rise during unloading by setting a lifting device, a base plate and a placement platform. However, when facing materials with irregular shapes, smooth surfaces or large weights, due to the lack of an effective clamping mechanism, the materials are prone to slipping and tipping over during the lifting process, posing a safety hazard. Moreover, it is difficult to ensure the accuracy of the placement position by relying solely on manual placement and transfer of materials, which affects subsequent transportation and processing, and needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to solve the technical problems raised in the above background technology.

[0004] The present invention adopts the following technical scheme: a logistics unloading mechanism comprises a base, the surface of the base is fixedly mounted with a moving wheel and a steering motor, the output end of the steering motor is fixedly mounted with a lifting frame, the surface of the lifting frame is fixedly mounted with a lifting motor, the output end of the lifting motor is fixedly mounted with a lifting threaded rod, the surface of the lifting threaded rod is threadedly connected with a lifting block, the surface of the lifting block is fixedly mounted with a tilting motor, the output end of the tilting motor is fixedly mounted with a tilting shaft, the surface of the tilting shaft is fixedly mounted with a telescopic rod frame, the surface of the telescopic rod frame is fixedly mounted with an electric telescopic rod, the output end of the electric telescopic rod is fixedly mounted with a unloading frame, the surface of the unloading frame is fixedly mounted with a supporting plate, a clamping motor, and a clamping slide rod, the output end of the clamping motor is fixedly mounted with a clamping threaded rod, the surface of the clamping threaded rod is threadedly connected with a clamping plate, a slide groove is provided on the surface of the clamping plate, and a spring is fixedly mounted on the bottom surface of the clamping plate, the other end of the spring is fixedly mounted with a pressure plate, and the surface of the pressure plate is fixedly mounted with a clamping pad.

[0005] Preferably, the clamping threaded rod is a bidirectional threaded rod, and the clamping plates are two and symmetrically distributed at both ends of the clamping threaded rod. This allows for synchronous movement in opposite directions, ensuring uniform and stable clamping force on the material, and preventing material tilting or damage due to uneven force. The symmetrical structure also effectively balances lateral forces during unloading, preventing the unloading frame from shifting during operation, significantly improving the safety and reliability of the unloading mechanism. It is also suitable for the rapid and precise clamping of materials of different specifications and shapes, greatly enhancing the versatility and practicality of the unloading mechanism.

[0006] Preferably, the lengths of the clamping threaded rod, the clamping slide, and the material support plate are all equal, and the surface of the clamping slide is in sliding connection with the surface of the chute. Here, the equal lengths allow the clamping plate to maintain a parallel trajectory with the material support plate as it moves along the threaded rod, avoiding wobbling and offsetting caused by length differences, and preventing the material from slipping or being damaged during the clamping process. The sliding fit between the clamping slide and the chute provides a stable guide support for the clamping plate, reducing frictional resistance during movement, and making the clamping action smoother and more efficient.

[0007] Preferably, there are three springs evenly distributed on the bottom surface of the clamping plate, and the side of the pressure plate can be slidably connected between the spring and the inner side of the clamping plate. Here, the spring can ensure that the pressure plate is subjected to balanced force at all parts when contacting the material, avoiding excessive local pressure that may cause indentations or damage to the material surface. The spring gives the pressure plate adaptive adjustment capabilities. When facing materials with irregular shapes or uneven surfaces, the pressure plate can adjust the fitting angle and force through the expansion and contraction of the spring, ensuring a tight clamping without destroying the material shape. The spring can effectively absorb vibration and impact during the unloading process, reducing the shaking of the material during transportation and unloading, ensuring the safety and stability of the unloading operation, and extending the service life of the unloading mechanism.

[0008] Preferably, a pushing motor and a slide fixing block are fixedly mounted on the surface of the supporting plate, a pushing threaded rod is fixedly mounted on the output end of the pushing motor, a pushing slide is fixedly mounted on the surface of the slide fixing block, the surface of the pushing threaded rod is threadedly connected to a pushing plate, and a pushing slide hole is provided on the surface of the pushing plate. Here, the pushing motor drives the pushing threaded rod to rotate, and the rotational motion is converted into the linear motion of the pushing plate through the threaded transmission, providing stable and controllable power for pushing materials, and the cooperation between the pushing slide and the pushing slide hole on the pushing plate plays a role of precise guidance, which can effectively limit the movement direction of the pushing plate and avoid its deviation or shaking during the pushing process, ensuring that the material is pushed smoothly along the preset path, not only can the pushing distance of the pushing plate be controlled according to different unloading requirements to achieve orderly unloading of materials, but also it can adapt to materials of different weights and specifications through the control of the motor, thereby improving the unloading efficiency and accuracy, and ensuring the continuity and efficiency of the logistics unloading operation.

[0009] Preferably, the length of the pusher threaded rod and the length of the pusher slide are equal and symmetrically distributed on both sides of the pusher plate, and the surface of the pusher slide hole and the surface of the pusher slide are slidably connected. Here, the symmetrically distributed equal-length rods can provide uniform force support when the pusher plate moves, effectively balancing the lateral force generated by uneven material weight or the pushing process, avoiding problems such as tilting and jamming of the pusher plate, and ensuring smooth and straight material transportation. The pusher slide strengthens the guiding function, so that the pusher plate moves along a predetermined trajectory under the drive of the pusher threaded rod, thereby improving the pushing accuracy, not only improving the reliability of the unloading operation, but also reducing the mechanical wear caused by uneven structural force, extending the service life of the unloading mechanism, enhancing the adaptability of the unloading mechanism to different working conditions and material types, and improving the overall efficiency and stability of the logistics unloading operation.

[0010] A method for a logistics unloading mechanism, comprising the following steps: Step 1: The moving wheel moves to the designated position with the cooperation of the steering motor, and the lifting motor drives the lifting threaded rod to drive the lifting block to rise to the appropriate height to pick up the material. The electric telescopic rod is extended and retracted to lift the material onto the supporting plate; Step 2: The clamping motor drives the clamping threaded rod to rotate, causing the two clamping plates to move toward each other. Cooperating with the spring, pressure plate and clamping pad, the clamping plates adhere to the surface of the material and fix the material, thus completing the stable clamping of the unloaded material. Step 3: The tilting motor drives the tilting shaft to rotate, causing the unloading rack to tilt. The pushing motor drives the pushing threaded rod to rotate. The pushing plate, guided by the pushing slide rod, pushes the material from the supporting plate to complete the unloading. All components work together to ensure stable material transportation and accurate unloading.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the present invention, by arranging a lifting threaded rod, a discharge rack, a supporting plate, a clamping threaded rod, and a clamping plate, and utilizing the synergistic effect of these structures, the lifting threaded rod drives the discharge rack to perform vertical lifting under the drive of the lifting motor, and the unloading height is adjusted to meet the needs of different loading and unloading scenarios. The supporting plate is used to carry materials, and the clamping plate can make the symmetrically distributed clamping plates move synchronously through the rotation of the bidirectional threaded rod, thereby stably clamping the materials and preventing them from slipping during the unloading process. The discharge rack provides support for the overall structure, and with the cooperation of components such as the electric telescopic rod, it realizes the inclined unloading action, thereby improving the unloading efficiency, enhancing the stability and safety of the unloading process, and being able to adapt to the loading and unloading of materials of various specifications, thereby improving the practicality and versatility of the logistics unloading mechanism.

[0012] 2. In the present invention, by setting a pushing motor, a pushing threaded rod, a pushing slide, a pushing plate, and a pushing slide hole, and utilizing the synergistic effect of these structures, the pushing motor serves as a power source to drive the pushing threaded rod to rotate, thereby providing stable power for pushing materials. The pushing slide rod and the pushing slide hole on the pushing plate slide together to form a precise guiding structure, which effectively limits the movement trajectory of the pushing plate, avoids its deviation or shaking during the pushing process, and ensures smooth material transportation. Driven by the threaded rod and guided by the slide rod, the pushing plate can flexibly adjust the pushing distance and speed according to the unloading requirements to achieve quantitative and orderly unloading. These structures cooperate with each other, which not only improves the unloading efficiency and accuracy, but also reduces mechanical wear and extends the service life of the equipment. At the same time, it also enhances the adaptability of the unloading mechanism to different materials and working conditions, ensuring the efficient and stable operation of logistics unloading operations.

Here, the equal length allows the clamping plate 17 to be fixedly mounted on the surface of the When moving along the threaded rod, the movement trajectory always remains parallel to the supporting plate 13, avoiding shaking and offset caused by length difference, preventing the material from slipping or being damaged during the clamping process, and the sliding cooperation between the clamping slide bar 16 and the slide groove 18 provides a stable guide support for the clamping plate 17, reducing the friction resistance during the movement, making the clamping action smoother and more efficient. The surface of the clamping threaded rod 15 is threadedly connected with the clamping plate 17. The clamping threaded rod 15 is a bidirectional threaded rod. There are two clamping plates 17 and they are symmetrically distributed at both ends of the clamping threaded rod 15.

Example

[0018] See also Figure 5 The surface of the supporting plate 13 is fixedly mounted with a pushing motor 22 and a slide fixing block 24. The output end of the pushing motor 22 is fixedly mounted with a pushing threaded rod 23. Under the drive of the pushing motor 22, the rotary motion is converted into a linear motion of the pushing plate 26 through a threaded connection with the pushing plate 26, pushing the material to move. The surface of the slide fixing block 24 is fixedly mounted with a pushing slide rod 25, which cooperates with the pushing slide hole 27 on the pushing plate 26 to provide a guide for the movement of the pushing plate 26, ensuring that the pushing plate 26 pushes the material smoothly along the predetermined path.
