Description

Technical Field

[0001] This utility model relates to the field of express delivery technology, and in particular to a correction structure for express delivery conveyors. Background Technology

[0002] Express delivery conveyors are widely used in the logistics industry to achieve efficient parcel transportation. In existing technology, conveyors typically employ belt or roller structures, driven by motors for continuous transport. To prevent conveyor belt deviation, common correction devices include mechanical guide wheels, pneumatic adjustment devices, or electronic sensor control systems. Mechanical guide wheels guide the conveyor belt back to the correct track through contact with its edge; pneumatic devices use air pressure to adjust the guide wheel angle; and electronic sensors detect deviation signals to drive the motor for correction. These devices can maintain the stability of the conveyor belt to a certain extent during the high-speed operation of express delivery conveyors, meeting basic logistics transportation needs.

[0003] However, existing deviation correction devices have significant drawbacks. Mechanical guide wheels have a simple structure but lack cushioning, making them prone to wear or failure due to deviation impacts; pneumatic devices, while flexible in adjustment, have complex structures and high maintenance costs; electronic sensor systems rely on electricity and complex circuits, resulting in a high failure rate and poor environmental adaptability. Furthermore, existing devices exhibit low deviation correction efficiency in scenarios with frequent deviations or high-speed operation, making it difficult to balance durability and low cost, thus limiting the operational stability of express delivery conveyors and impacting logistics efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a correction structure for express delivery conveyors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A correction structure for a courier conveyor includes a support unit for fixing the correction structure, fixedly disposed on both sides of the conveyor bracket, including a fixing frame, a fixing plate fixed on the fixing frame, and a bracket fixed on one side of the fixing plate and extending to one side of the conveyor belt; a buffer unit elastically disposed on the support unit, including a movable tube movably sleeved at the end of the bracket, a limiting piece fixed on the bracket, a spring movably sleeved on the bracket, a connecting rod fixed at one end of the movable tube, and a fixing tube fixed at the end of the connecting rod, wherein the spring is located between the limiting piece and the movable tube, and the movable tube is elastically connected to the spring through the limiting piece; and a correction unit fixedly disposed at the end of the buffer unit for correcting the conveyor belt of the conveyor, including a support tube fixed inside the fixing tube, bearings fixed at the upper and lower ends of the inner wall of the support tube, and a correction rotating rod fixed by the inner ring of the bearing, the lower end of the correction rotating rod extending below the support tube.

[0007] Preferably, the support unit further includes mounting holes formed on the fixing frame for fixing the fixing frame to the conveyor support.

[0008] Preferably, the end of the bracket is provided with a first T-shaped head, and the inside of the movable tube near the bracket is provided with a boss that restricts the first T-shaped head from moving away from the limiting piece.

[0009] Preferably, a second T-shaped head is provided at the top of the correction rod, which is located above the bearing and is used to restrict the downward movement of the correction rod.

[0010] Preferably, the spring is compressed between the limiting plate and the movable tube. When the conveyor belt deviates, the movable tube slides along the support and compresses the spring to absorb the impact force.

[0011] Preferably, the bearing is a rolling bearing, and the correction rod is connected to the support tube with low friction through the rolling bearing to improve the correction efficiency.

[0012] This utility model has the following beneficial effects:

[0013] 1. This belt alignment structure effectively absorbs the impact force when the conveyor belt deviates, significantly improving the device's durability through the spring and movable tube design of the buffer unit. The spring elastically compresses between the limiting plate and the movable tube, mitigating the hard impact of lateral forces on the structure and reducing component wear. The limiting design of the first T-head and the boss further ensures the stable sliding of the movable tube, avoiding the risk of disengagement. This buffering mechanism makes the alignment process smoother, making it particularly suitable for the high-frequency operation of express delivery conveyors. Compared to the shortcomings of traditional mechanical guide wheels that directly bear the impact, this structure extends service life, reduces maintenance frequency and costs, and provides a more reliable conveyor belt alignment solution for the logistics industry.

[0014] 2. The correction unit employs a low-friction connection between rolling bearings and the correction rod, significantly improving correction efficiency and reducing energy consumption. The bearings are fixed to the inner wall of the support tube, allowing the correction rod to rotate flexibly and reducing frictional resistance when in contact with the conveyor belt. The second T-head design ensures the vertical stability of the rod during high-speed rotation, preventing it from falling off. This low-friction design makes the correction action more precise and faster, suitable for the high-speed transportation needs of express delivery conveyors. Compared with traditional correction devices, this structure reduces energy loss and component wear, improves the sensitivity of the correction response, and provides technical support for the efficient operation of the logistics system.

[0015] 3. This correction structure achieves ease of installation and maintenance through modular design, enhancing its practicality and adaptability. The mounting holes of the support unit facilitate fixing to different conveyor brackets, and the separate design of the buffer unit and correction unit facilitates disassembly and replacement. The simple structure and standardized components reduce production and maintenance costs, making it suitable for large-scale logistics applications. Compared to the high complexity and maintenance difficulty of pneumatic or electronic correction systems, this structure simplifies the operation process while maintaining efficient correction, adapting to various working environments and providing an economical and efficient solution for the rapid deployment and long-term stable operation of express delivery conveyors.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4A correction structure for a courier conveyor includes a support unit for fixing the correction structure, which is fixedly installed on both sides of the conveyor support and includes a fixing frame 1, a fixing plate 2 fixed on the fixing frame 1, and a bracket 3 fixed on one side of the fixing plate 2 and extending to one side of the conveyor belt; a buffer unit elastically installed on the support unit, including a movable tube 4 movably sleeved at the end of the bracket 3, a limiting piece 5 fixed on the bracket 3, a spring 6 movably sleeved on the bracket 3, a connecting rod 7 fixed at one end of the movable tube 4, and a fixing tube 8 fixed at the end of the connecting rod 7, wherein the spring 6 is located between the limiting piece 5 and the movable tube 4, and the movable tube 4 is elastically connected to the spring 6 through the limiting piece 5; and a correction unit fixedly installed at the end of the buffer unit for correcting the conveyor belt of the conveyor, including a support tube 9 fixed inside the fixing tube 8, bearings 10 fixed at the upper and lower ends of the inner wall of the support tube 9, and a correction rotating rod 11 fixed through the inner ring of the bearings 10, the lower end of the correction rotating rod 11 extending below the support tube 9.

[0023] In this embodiment, the conveyor belt deviation is effectively corrected through the coordinated action of the support unit, buffer unit, and correction unit. The support unit is securely installed on both sides of the conveyor support using a fixed frame 1, a fixed plate 2, and a bracket 3, ensuring overall stability. The buffer unit absorbs the impact of deviation through the elastic connection between the limiting plate 5 and the movable tube 4 via a spring 6, in conjunction with the connecting rod 7 and the fixed tube 8, thus improving durability. The correction unit supports the correction rotating rod 11 via a bearing 10 inside the support tube 9, achieving low-friction rotation and accurately guiding the conveyor belt back to the correct position. This structure improves correction efficiency, reduces wear and maintenance costs, and is suitable for high-speed logistics scenarios.

[0024] In this utility model, the support unit also includes a mounting hole 101 opened on the fixed frame 1, which is used to fix the fixed frame 1 on the conveyor support.

[0025] In this embodiment, a stable installation is achieved through the mounting holes 101 on the fixing frame 1, significantly enhancing the stability and adaptability of the structure. The mounting holes 101 are located on the fixing frame 1, facilitating the secure connection of the fixing frame 1 to both sides of the conveyor support using bolts or other fasteners, ensuring the positional stability of the correction structure during high-speed operation. Compared to traditional welding or complex fixing methods, the mounting hole 101 design simplifies the installation process, adapts to different conveyor support specifications, and improves the versatility of the device. Furthermore, this design facilitates disassembly and maintenance, reducing the cost of deploying and adjusting logistics equipment, and providing a reliable fixed foundation for the efficient and stable operation of the express delivery conveyor.

[0026] In this utility model, the end of the bracket 3 is provided with a first T-shaped head 301, and the inside of the movable tube 4 is provided with a boss 401 on the side near the bracket 3 to restrict the first T-shaped head 301 from moving away from the limiting piece 5.

[0027] In this embodiment, the cooperation between the first T-shaped head 301 at the end of the support 3 and the inner boss 401 of the movable tube 4 effectively enhances structural reliability and operational stability. The first T-shaped head 301 and the boss 401 form a limiting structure, restricting the movable tube 4 from moving away from the limiting piece 5, preventing it from detaching from the support 3 due to the spring force of the spring 6 or the impact of belt deviation. This design ensures that the movable tube 4 maintains controlled movement during elastic sliding, absorbing the impact of conveyor belt deviation while avoiding structural failure. Compared with traditional belt deviation correction devices with no limit design, this structure improves durability and safety, is suitable for high-frequency operation scenarios of express delivery conveyors, and reduces maintenance frequency and failure risk.

[0028] In this utility model, a second T-shaped head 1101 is provided at the top of the correction rod 11. The second T-shaped head 1101 is located above the bearing 10 and is used to restrict the downward movement of the correction rod 11.

[0029] In this embodiment, the design of the second T-shaped head 1101 at the top of the correction rod 11 significantly improves operational stability and durability. The second T-shaped head 1101 is located above the bearing 10, restricting the downward movement of the correction rod 11 and preventing it from falling off under high-speed rotation or conveyor belt misalignment impact. Combined with the low-friction support of the bearing 10, this structure ensures that the correction rod 11 maintains precise positioning and stable rotation when guiding the conveyor belt back to center. Compared to traditional correction devices with no fixed position design, this structure effectively avoids rod loosening or failure, extends service life, is suitable for high-frequency, high-speed operation scenarios of express delivery conveyors, reduces maintenance costs, and improves correction efficiency.

[0030] In this invention, the spring 6 is pressurized between the limiting plate 5 and the movable tube 4. When the conveyor belt deviates, the movable tube 4 slides along the bracket 3 and compresses the spring 6 to absorb the impact force.

[0031] In this embodiment, the spring 6, positioned between the limiting plate 5 and the movable tube 4, effectively absorbs the impact force when the conveyor belt deviates, improving the device's durability. When the conveyor belt deviates, the movable tube 4 slides along the bracket 3, compressing the spring 6. The elastic deformation of the spring 6 alleviates lateral impacts, protecting the correction structure from hard damage. This design ensures a smooth correction process, reduces component wear, and is particularly suitable for the high-frequency operating environment of express delivery conveyors. Compared to traditional rigid correction devices, this structure reduces maintenance frequency and failure rate through the buffering effect of the spring 6, providing an efficient and economical solution for the stable operation of logistics systems.

[0032] In this invention, the bearing 10 is a rolling bearing, and the correction rod 11 is connected to the support tube 9 with low friction through the rolling bearing to improve the correction efficiency.

[0033] In this embodiment, bearing 10 is used as a rolling bearing to achieve a low-friction connection between the correction rod 11 and the support tube 9, significantly improving correction efficiency. The rolling bearing 10 is fixed to the inner wall of the support tube 9, supporting the flexible rotation of the correction rod 11 and reducing frictional resistance when in contact with the conveyor belt, ensuring rapid and accurate guidance of the conveyor belt back to center. This low-friction design reduces energy loss and component wear, extending the device's service life, and is particularly suitable for the high-speed, high-frequency operation of express delivery conveyors. Compared to traditional sliding bearings or high-friction correction devices, this structure optimizes the correction response speed and stability through the rolling bearing 10, providing reliable support for the efficient operation of the logistics system.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
