[0024] The specific implementation process is as follows:

[0025] After the suction cup on the mechanical arm sucks up the ton bag and exposes the bag opening, the controller controls motor two 220 to start, and when motor two 220 runs, it drives the driving gear one above the support plate 206 to rotate, and when the driving gear one rotates, it drives the annular chain two 218 to move, and when the annular chain two 218 moves, it pulls the base plate 210 to move vertically up and down on the support plate 206, and when the height of the base plate 210 is the same as the height of the bag opening of the ton bag, the controller controls motor two 220 to stop running, and then starts motor one 219, and when motor one 219 runs, it drives the transmission gear to rotate, and when the transmission gear 208 rotates, it drives the chain one to move, and when the chain one moves, it drives the moving plate 204 to move towards the bag opening of the ton bag, and since the support plate 206 is fixedly connected to the moving plate 204, the support plate 206 is fixedly connected to the moving plate 204 through the connecting plate 211, and the circumference of the circular plate 212 is rotatably connected to four evenly spaced support rods 213, so the moving plate 204 moves synchronously with the support rods 213, until the support rods 213 are inserted into the bag opening of the ton bag, at which time the controller stops the operation of motor one 219, and then starts the bag supporting cylinder to extend the output shaft of the bag supporting cylinder, and when the output shaft of the bag supporting cylinder extends, it pushes the linkage plate 214 to move in the extension direction of the output shaft of the bag supporting cylinder, and when the linkage plate 214 moves, the four linkage rods 215 gradually change from an inclined state to a state perpendicular to the support rods 213, at which time the four support rods 213 are lifted by the linkage rods 215, increasing the distance between the support rods 213, and as the distance between the support rods 213 increases, the support rods 213 open the bag opening of the ton bag, allowing the bag opening to assume a rectangular shape, facilitating the clamping of the ton bag by the mechanical arm in the next process. After the ton bag mechanical arm clamps it, the controller controls the output shaft of the bag supporting cylinder to shorten, and when the output shaft of the bag supporting cylinder shortens, it drives the linkage plate 214 to return to the original position, and in the process of returning to the original position, the linkage plate 214 pulls the linkage rod 215, and then the linkage rod 215 gradually changes from a vertical state to an inclined state, and in this process, the linkage rod 215 pulls the support rods 213 towards the center, at which time the support rods 213 are disengaged from the bag opening of the ton bag. Then the controller controls motor one 219 to start in reverse, and when motor one 219 runs in reverse, it drives the moving plate 204 to reverse on the rectangular frame 202 and return to the original position, thereby driving the support rods 213 out of the bag opening of the ton bag.
