Description

Technical Field

[0001] The utility model relates to the technical field of rubber tire production, in particular to a tire strip shaping device for a rubber tire. Background Art

[0002] Rubber tires are round rubber products used on vehicles. Their primary function is to provide support, shock absorption, and traction. They are typically constructed from multiple layers of material, including an inner tube, a ply (such as nylon or polyester), and a rubber outer layer. During tire production, a bead former is used to create the bead strips on the outer rubber layer of the tire.

[0003] The strip shaper commonly used for rubber tires at present is to directly put the rubber tire on the strip shaper, and then use the strip shaper to cut the strip on the rubber tire. Although this is simple to operate, the rubber tire put on the strip shaper has inconsistent putting positions, which requires frequent adjustment of the strip cutting knife on the strip shaper. In addition, the rubber tire put on the strip shaper may be displaced by external force during the strip cutting process or the rotating rubber tire may be displaced, which will affect the strip shaping and cutting quality of the rubber tire.

[0004] Therefore we have proposed a tire strip shaping device for rubber tire to solve the above problems. Utility Model Content
