Automatic transmission device

The flexible and rotatable chain is used to drive the tray to move forward and backward, and the chain is led to the outside of the sterilization cabinet through an external shaft. The outside is equipped with a servo motor or asynchronous motor+frequency converter for smooth acceleration and deceleration; Due to the lack of high concentration EO gas in the preheating room and analysis room, the transmission mechanism is directly connected to the room content for transmission.
