At the bag loading station, the claw opening mechanism 6 separates the outer claw A37 and the outer claw B38, the inner claw A39 and the inner claw B310 of a group of clamping mechanisms 3 to clamp the four corners of the folding bag, and then the outer claw A37 and the outer claw B38, the inner claw A39 and the inner claw B310 are closed to clamp the folding bag, and then the rotary positioning disk body 1 is rotated to rotate the group of clamping mechanisms 3 to the bag opening station and the blanking station in turn, and the cam 2 starts to rotate at the bag opening station, and the rotation of the cam 2 drives The transmission track slider 4 moves back and forth along the transmission track, thereby driving the push rod 5 to move. The movement of the push rod 5 drives the gear transmission shaft 325 to rotate, thereby driving the rack to move along the gear groove 321. The movement of the rack drives the slide rail support block 34 to move along the sliding track 33, thereby driving the outer claw fixing block 35 and the inner claw fixing block 36 to move back and forth, and further drives the outer claw A37 and the outer claw B38, the inner claw A39 and the inner claw B310 to move back and forth, pull the four corners of the angle bag apart, and then drop the material. After the drop is completed, the cam 2 rotates to reset and close the outer claw A37 and the outer claw B38, the inner claw A39 and the inner claw B310, and then the rotating positioning plate body 1 continues to rotate to perform the actions of the subsequent workstations to complete the entire packaging process.
