AI Technical Summary
In existing twin-screw drive mechanisms, different feeding rates require replacing the motor or output screw, which is inconvenient to operate.
By adding a set of drive gears to the existing structure, and through a one-way bearing and a transition gear set, different drive gears can work when the motor rotates in both directions, thereby achieving power transmission with different speed ratios, while the output shaft rotation direction remains unchanged.
This allows for changing the feed rate within the same transmission box by rotating the motor forward and backward without replacing the screw and motor, thus improving operational flexibility and efficiency.
