[0049] See also Figures 1 to 14 As shown, the working method of a bionic manipulator with bag-rolling function in this embodiment is as follows:
[0050] Step 1: The initial position of the bag feeding mechanism is: the guide rod of the bag-supporting and flipping cylinder extends, pushing the connecting plate and the rotating shaft to rotate counterclockwise to turn the clamping plate and the front clamping plate to the initial state of the clamping plate;
[0051] Step 2: When the material bag moves to Fig.13 When the bag is in the position, the clamping plates of the bag feeding mechanism clamp the two sides of the material bag, and the bag opening mechanism opens the material bag. At this time, the guide rod of the rotating arm cylinder extends to drive the two clamping arms to rotate toward each other to give the material bag the space it needs when opening the bag mouth.
[0052] Step 3: When the bag opening is opened, the guide rod of the bag flipping cylinder shrinks, pushing the connecting plate and the rotating shaft to rotate clockwise to turn the clamping plate and the front clamping plate to insert the clamping plate into the bag opening;
[0053] Step 4: After completing the above actions, the clamp arm drives the driving wheel to rotate counterclockwise under the drive of the motor, and the driving wheel drives the driven wheel to rotate counterclockwise through the transmission chain, and the driven wheel drives the clamp arm to turn 90 degrees counterclockwise to enter the canning position;
[0054] Step 5: After the canning is completed, the material bag is handed over to the canning mechanism. At this time, the clamp arm drives the driving wheel to rotate clockwise under the drive of the motor, and drives the driven wheel to rotate clockwise through the transmission chain to move the clamp arm to the initial position to deliver the next material bag.
