Abstract

This invention provides an adjustable bead-fitting device, comprising a hollow fixing frame and a detachable fixing plate assembly mounted on the fixing frame. The fixing plate assembly includes a fixing plate with a hollow receiving hole for a forming drum to pass through. The fixing plate assembly also includes several fixing elements disposed near one end of the receiving hole, with the fixing elements evenly distributed along the circumference of the receiving hole. This invention primarily utilizes a newly designed bead-fitting device with a detachable fixing plate assembly. When producing tires with large diameter variations across different sizes, the fixing plate assembly can be replaced as a single unit, enabling rapid changeover. Conversely, when producing tires of the same size but different types with small diameter variations, a drive mechanism adjusts the positions of the bead-fitting elements, allowing for production without replacing the fixing plate assembly and providing a rapid production response.
