[0002] After the tire blank is formed, it needs to be transported to other processes by a conveyor belt for subsequent processing. During tire blank processing, a robot is generally required to grab the tire blank onto a tire blank support to fix the tire blank position. However, the position of the tire blank on the conveyor belt is uncertain, which leads to inaccurate and inconvenient grabbing by the robot, or even failure to grab, resulting in an unsmooth production line or even interruption. Therefore, those skilled in the art need to develop a centering device that cooperates with a conveyor belt and can adapt to tires of different specifications. Utility Model Content

[0005] The tire is placed flat on the conveyor belt for transportation. When the tire is transported to the middle of the centering assembly, the driving assembly drives the two moving rods to move synchronously, thereby driving the brackets in the two roller groups to move closer to the middle position. The rollers on the four brackets squeeze the outer wall of the tire and finally center the tire. Then the two roller groups move away from each other to release the tire, making it convenient for the conveyor belt to transport the tire to the next process for production and processing. The moving rod is set below the conveyor belt to avoid interference with the tire.

[0006] Furthermore, in order to drive the two roller groups to move synchronously closer or farther away, thereby realizing the centering action of the tire, the driving assembly includes two slide rails arranged along the width direction of the conveyor belt, and slides are slidably arranged on the two slide rails. Two moving rods are respectively fixedly connected to the two slides, and racks are arranged on the side where the two slides are close to each other. A central gear meshing with the two racks is arranged between the two racks, and the central gear is rotatably connected to the frame. The central gear cooperates with the two racks arranged in parallel, so that the two slides can move synchronously the same distance on the slide rails to ensure the accuracy of tire centering. The driving force for tire centering can be manual, can be a cylinder connected to the moving rod, a telescopic motor or a hydraulic cylinder, or can be a motor connected to the central gear transmission.

[0007] Furthermore, a cylinder parallel to the axis of the slide rail is provided on the frame, a cylinder body of the cylinder is fixedly connected to the frame, and an output end of the cylinder is fixedly connected to one of the slides or the moving rod.

[0008] Furthermore, in order to improve the conveying capacity of the conveying roller for the tire and prevent slipping between the tire and the conveying roller, the conveying roller includes a central axis and a plurality of omnidirectional wheels sleeved on the central axis, and the cross section of the central axis is a polygon.

[0009] Furthermore, in order to prevent the conveyor roller from bending and deforming due to long-term use, a support frame is provided on the center line of the conveyor belt, and a plurality of bearing seats are provided on the support frame. Bearings are provided in the bearing seats. The positions and quantities of the bearings correspond one-to-one with the conveyor rollers, and the inner ring of the bearing is provided in a sleeve that cooperates with the center shaft.

[0010] The beneficial effects of the utility model are as follows: the utility model provides a tire centering device, which adopts two figure-eight roller groups symmetrically arranged on the conveyor belt, and centers the tire on the conveyor belt by synchronously moving the two roller groups to the center position. It can adapt to tires of various specifications, is convenient and fast, and has a good centering effect. BRIEF DESCRIPTION OF THE DRAWINGS
