Description

Technical Field

[0001] This utility model relates to the field of vulcanization equipment technology, specifically to a tire storage device with interconnected internal and external supports. Background Technology

[0002] Before the tire blank is fed into the vulcanizing machine for vulcanization, it generally needs to be placed on a tire holder for easy handling by a robotic arm. The existing tire holders mainly consist of a tray and inner and outer supports on the tray. Typically, the inner support is fixed to the tray, while the outer support can be adjusted radially. This type of tire holder cannot adapt to working conditions with large differences in rim diameter. In addition, some tire holders have radially adjustable inner and outer supports. However, multiple inner or outer supports cannot be adjusted in unison, which makes the actual operation not only time-consuming and labor-intensive, but also results in inaccurate adjustments.

[0003] Therefore, developing a tire storage device that can be adjusted independently and in a coordinated manner with multiple internal and external supports, with precise adjustment dimensions applicable to tire blanks of different inner and outer diameters, and which is easy to operate and saves time and effort, is an urgent problem to be solved at this stage. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a tire holder with interconnected inner and outer supports. When the inner drive plate rotates relative to the fixed plate, the first connecting rod and the first moving block can drive all the inner claws to move radially synchronously, realizing the linkage adjustment of multiple inner supports. When the outer drive plate rotates relative to the fixed plate, the second connecting rod and the second moving block can drive all the outer claws to move radially synchronously, realizing the linkage adjustment of multiple outer supports. The radial positions of the inner and outer claws can be easily adjusted according to the inner and outer diameters of the tire blank.
