The double‑speed chain conveyor is a core key equipment for flexible assembly and automatic circulation in the field of intelligent manufacturing. Relying on the unique differential speed transmission principle, it realizes low‑speed operation of chains and high‑speed transportation of tooling plates. It supports workpiece accumulation and buffering at stations, precise positioning and independent operation without stopping the whole production line. With the core advantages of stable and efficient performance, strong adaptability and easy automation integration, it is widely used in automated assembly lines of various industries and serves as standard equipment for production lines.
