Description

Technical Field

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

[0002] The cap strip winding method is based on the original winding method, and is wound two more times in the center area. The wound cap strip is used to supplement the rubber material lacking in the center area of the tread, thereby avoiding the uneven appearance quality defect of the tire caused by the flow of rubber material around the tread, improving the appearance inspection pass rate, simplifying the process flow, and improving product quality. In the tire molding process, when the tube strip is wound, the tire is rotated by a rotating clamping device, so that the tube strip can be smoothly wound on the tire. When cutting the cap strip, the electric push rod drives the cutter to clamp the cap strip to cut the cap strip. Since the cap strip itself has a certain elasticity, when it is cut, the cutter contacts it, and the tube strip generates elastic force under the action of the extrusion pressure, which is easy to produce a large deformation, causing the tube strip to shift. In actual operation, it is easy to cause the cap strip to not be completely cut, and some cap strip fractures still have connected parts, affecting the cutting quality. For this reason, we propose a cap strip winding device for a tire molding machine. Utility Model Content
