The belt pulleys 20 are installed on the bearing seats 24 through a rotating shaft 25.

[0023] The moving mechanism 4 further includes a linear slide rail 26. The linear slide rail 26 is arranged on the frame 1 between the two moving frames 6. The end of the moving frame 6 is fixed to the slider 27 by bolts, and the slider 27 is slidably assembled on the linear slide rail 26. The first motor 7 is installed on the frame 1.

[0024] The centering mechanism 5 further includes three columns, which are divided into a first column 29, a second column 30, and a third column 31. The first column 29, the second column 30, and the third column 31 are all installed on the frame 1. The rack 14 is arranged along the height direction of the first column 29. Linear guide rails 32 are arranged on the second column 30 and the third column 31.

That is to say, the claw pieces 11 can be evenly distributed, and the claw piece structure can be matched with the bead, which can well protect the embryo 47. The claw pieces 11 are fixed to the top of the fixed tire retaining plate 41, and there are protrusions 42 on the outside of the claw pieces 11. The opening and closing of the claw pieces 11 are driven by the second servo motor 35 to achieve centering of the embryo 47. Through the feedback of the driving torque of the second servo motor 35, the radial force of the claw pieces 11 supporting the embryo 47 can be controlled to avoid over-expansion and damage to the embryo 47. That is, the claw pieces 11 support the upper steel ring of the embryo 47, and the upper steel ring and upper tread of the embryo 47 are not easily deformed.

[0026] In the present utility model, before conveying the embryo, the first motor 7 can be actuated to make the two moving frames 6 move inwards or outwards synchronously to adapt to different specifications of embryos. The tire embryo 47 is first conveyed to the conveying mechanism 3 through the tire retaining roller path 2, and then conveyed to the upper part of the centering mechanism 5 by the third motor 19 driving the conveyor belt 9 to realize the storage and transportation of the tire embryo 47. Subsequently, through the gear 13 and the rack 14 of the lifting assembly, the centering mechanism 5 can be raised or lowered. Then, through the action of the second servo motor 35 and the second screw rod 36 connected to the second servo motor 35, the moving seat 38 can be driven to rise or fall. Then, with the movement of the moving seat 38, the first connecting rod 39 can be driven to rotate, so as to realize the opening or closing of the fixed tire retaining plate 41, that is, to drive the claw pieces 11 to open or close. The lower bead of the tire embryo 47 will be stuck under the protrusion 42 of the claw pieces 11, and the external manipulator can grasp the upper bead of the tire embryo 47, so as to realize the correction and straightening of the tire embryo 47, reduce the deformation of the embryo 47, improve the shaping success rate after the embryo 47 enters the center of the mold, reduce the occurrence of production defects. At the same time, through the feedback of the driving torque of the second servo motor 35, the tensile force on the embryo 47 can be controlled to avoid over-stretching and damage to the embryo 47.

[0027] Driven by the servo motor, the present utility model improves the production efficiency as a whole, is more energy-saving, has high action responsiveness, and the action is more stable. The tire is not easily tilted, and the centering degree is better. And the entire tire retaining device has no cylinder drive, and all cables are quickly connected and disconnected through aviation plugs, saving the workload required for removing and resetting the tire retaining device during mold change and eliminating the work of manually connecting the compressed air pipe.
