Description

Technical Field

[0001] This utility model relates to the field of tire rubber processing technology, specifically to a quick-change device for triangular rubber pressing rollers. Background Technology

[0002] The rubber tire triangular rubber pressing roller is a pressing roller device used in the tire manufacturing process to press the triangular rubber together. Its main function is to improve the discharge of excess air between the triangular rubber and the tire carcass cord, thereby comprehensively improving the bonding quality between the various components and thus enhancing the manufacturing quality of the tire.

[0003] According to the tire bead forming process, the triangular rubber strip is first bonded to the steel rim, and the bead bonding area is then rolled and sealed. The completed bead is then removed, a new steel rim is re-installed, and the next forming cycle begins. Currently, all processes are completed in a series. In actual production, operators will change the rubber strip width according to the tire factory's requirements. Different widths of rubber strips require different roller shapes, therefore the roller device for rolling and sealing the bead bonding area needs to be changed in real time. If different widths of rubber strips are frequently changed, the cumulative time spent changing the roller device in a conventional structure is long, affecting production efficiency.
