Document Type and Number:
WIPO Patent Application WO/2023/241707
Kind Code:
A1
Abstract:
A roller turn-up mechanism and a mechanical drum. The roller turn-up mechanism is arranged on a spindle assembly (10) and comprises a plurality of first turn-up structures (20), which are arranged circumferentially around the spindle assembly (10), wherein each first turn-up structure (20) comprises: a roller assembly (201) for rolling a sidewall (50) of a tire; a first drive rod (21), which is in drive connection with the roller assembly (201); a first drive assembly (211), which is connected to the first drive rod (21) to drive, by means of the first drive rod (21), the roller assembly (201) to move in the radial direction of the tire; a support assembly (25), which is connected to the first drive rod (21) to support the sidewall (50) outside a roller turn-up mechanism; a second drive assembly (221), which is connected to the support assembly (25) to drive, by means of the support assembly (25), the roller assembly (201) to tightly press the tire, the roller assembly (201) being arranged on the support assembly (25); and a second drive rod (22), which is connected to the second drive assembly (221), and is also rotationally connected to the first drive rod (21), wherein one end of a third drive rod (23) is rotationally connected to the end of the support assembly (25) away from the roller assembly (201), and the other end thereof is rotationally connected to the second drive rod (22); and the second drive assembly (221) drives the second drive rod (22) to move, so as to separately drive the first drive rod (21) and the third drive rod (23) to rotate. The roller turn-over mechanism solves the problem in the prior art of wrinkles easily occurring when a mechanical drum rolls a sidewall.
