Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a roller conveyor drive device. Background Technology

[0002] Currently, roller conveyors are commonly used in automated production lines and logistics sorting systems, widely applied in workpiece transfer, packaging, assembly, and warehousing. Existing roller conveyor systems generally employ a single drive mechanism, where a single motor drives the drive roller to rotate, which in turn drives multiple conveyor rollers via synchronous belts or chains to achieve material transport. While this structure can fulfill basic conveying functions, its overall structure is simple, its control method is simplistic, and it is difficult to achieve dynamic adjustment of the conveying direction and angle.

[0003] In a typical structure, the drive roller of the existing conveyor is fixedly mounted on the conveyor frame, and its drive motor output is only used to drive the transmission chain or synchronous belt in one direction, which cannot achieve overall deflection of the conveyor platform. When the production line needs to change the conveying direction or realize multi-station diversion, it is often necessary to complete the direction switching by external mechanical turntable or manual handling. This not only occupies extra space, but also the adjustment process is complicated, which can easily cause positioning errors and affect the continuity of production and the degree of automation.

[0004] Furthermore, traditional roller conveyors mostly operate with open-loop drive control systems, lacking real-time monitoring and feedback of roller speed and conveyor seat angle. Without angle detection and speed control modules, the conveying system cannot automatically adjust its output power according to load changes, leading to speed differences between rollers, uneven conveying, material misalignment, and even jamming. While some improved designs have added angle adjustment mechanisms, most rely on mechanical limits or manual calibration, resulting in low control precision and limited adjustment frequency, failing to meet the dynamic control requirements of modern intelligent manufacturing systems.

[0005] In view of this, we will study and improve the existing problems and provide a roller conveyor drive device to solve the current problems. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is: a roller conveyor drive device, including a conveyor base and a drive assembly.

[0008] The conveyor seat is rotatably mounted with an active roller, a shaft, and several conveying rollers for carrying and conveying materials. A synchronous transmission box is fixedly installed on one side of the conveyor seat to realize synchronous transmission between the active roller and the several conveying rollers. The active roller and the shaft are respectively provided with meshing transmission wheels and bevel gear shafts. A turntable gear is fixedly installed at the bottom of the conveyor seat. The drive assembly includes a drive platform, a first drive motor, and a second drive motor. The two motors are respectively connected to the turntable gear and the bevel gear shaft for synchronous control of the conveyor seat angle deflection and roller drive.

[0009] This device can achieve adjustable conveying direction and synchronous drive of multiple rollers through a dual-drive system during the conveying process, ensuring smooth conveying and accurate system response.

[0010] In a preferred example, the output shaft of the second drive motor is coaxially arranged with the turntable teeth, which are rotatably mounted on the surface of the drive table.

[0011] Specifically, this coaxial arrangement structure can reduce eccentric loads, improve the rotational accuracy and stress stability of the turntable teeth, thereby making the deflection action of the conveyor seat smoother and more reliable.

[0012] In a preferred embodiment, a transmission shaft is rotatably mounted on the surface of the drive platform, the output end of the first drive motor meshes with the surface of the transmission shaft for transmission, and one end of the transmission shaft is connected to the turntable teeth via a belt.

[0013] Specifically, this structure forms a flexible transmission path, which can reduce the impact force of the motor output while ensuring power transmission efficiency, thereby improving the stability and vibration resistance of the system operation.

[0014] In a preferred example, an angle sensor is fixedly installed on the bottom surface of the drive platform. The angle sensor is connected to the bottom end of the drive shaft and is used to monitor the rotation angle of the drive shaft, thereby realizing real-time detection of the deflection state of the turntable teeth and the conveyor seat.

[0015] Specifically, the sensing system can form a closed-loop feedback control, which, combined with the electronic control module, enables precise adjustment of the conveying direction and angle, ensuring the accuracy and consistency of the conveying system's actions.

[0016] In a preferred example, the synchronous transmission box is equipped with a transmission chain or synchronous belt structure to connect the drive roller and several conveying rollers to achieve stable synchronous transmission.

[0017] Specifically, this structure ensures that the rotation speed of each roller is consistent, preventing materials from shifting, piling up, or slipping due to asynchrony during the conveying process, thereby improving the operational stability and accuracy of the conveyor line.

[0018] In a preferred example, the transmission ratio between the bevel gear shaft and the second drive motor is preset according to the conveying pitch to adjust the conveying speed and rotational balance.

[0019] Specifically, by setting the gear ratio appropriately, the speed can be flexibly adjusted according to the material weight and conveying pitch, maintaining a constant linear speed and low noise operation, and ensuring the uniformity of the conveying effect.

[0020] In a preferred example, both the first drive motor and the second drive motor are adjustable speed motors and are electrically connected to an independent electronic control module to adjust the output speed in real time according to the load being transported.

[0021] Specifically, through this independent control method, the system can automatically match the optimal power output according to the conveying status, realize synchronous speed control of the drive roller and shaft, avoid overload operation, and improve the overall energy efficiency and control accuracy.

[0022] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting up a dual-drive structure with a first drive motor and a second drive motor, combined with the linkage design of the turntable gear and synchronous transmission box, the angle deflection adjustment of the conveyor seat and the synchronous drive of multiple rollers are realized. This structure can achieve flexible control of the conveying direction while maintaining the smoothness of conveying, significantly improving the adaptability and operating efficiency of the material conveying device.

[0023] 2. In this utility model, by setting an angle sensor at the bottom of the drive table and forming a closed-loop control system with the electronic control module, the deflection status of the turntable teeth and the conveyor seat can be monitored in real time, so as to achieve precise control of the conveying direction and running speed, ensuring the stability and positioning accuracy of the conveying process, and improving the automation level and operational reliability of the overall system.

[0037] The first drive motor 220 and the second drive motor 230 are fixedly mounted on the surface of the drive platform 210, serving as the steering drive source and the conveying drive source, respectively.
