Their performance requirements are exceptionally high, necessitating sophisticated technology and equipment in both manufacturing and recycling. Bead cutting and stripping devices are among the highly specialized pieces of equipment used in aircraft tire manufacturing and recycling. Because aircraft tire beads typically contain robust bundles of steel wires to ensure airtightness and structural strength between the tire sidewall and the rim, specialized equipment is needed to handle these steel wires during material separation in tire recycling or production processes.

[0003] For example, in a class of prior art represented by application number CN202020792729.8, the main structure includes a cutting assembly installed at the end of the workbench mechanism, a movable roller assembly with adjustable spacing installed on the workbench, horizontal moving slide rail assemblies installed on both sides of the workbench mechanism, and a clamping assembly installed on the horizontal moving slide rail assembly; a bead traction mechanism, installed on the workbench mechanism behind the bead cutting mechanism, is used to transport the cut bead to the bead stripping mechanism; the bead stripping mechanism, installed on the workbench mechanism, includes a bead stripping assembly, a debris storage box located directly below the bead stripping assembly, a wire traction assembly located behind the bead stripping assembly, and a wire storage box located below the wire traction assembly.
