[0036] The working process and working principle of the utility model are as follows:

[0037] When the utility model is in the initial state, the piston rod of the clamping plate cylinder 3 is retracted, the clamping plate 8 is opened, the piston rod of the lifting cylinder 9 is retracted, the piston rod of the tensioning cylinder 15 is retracted, the pneumatic clamp mechanism is in a high position, away from the bag clamping opening at the lower end of the bag clamp body 1, and is in an open state.

[0038] After the bagging robot gloves are put on the bag, the piston rod of the clamp cylinder 3 extends out, the clamp 8 closes, clamps the bag, and presses the bag against the wide side plate 1.1. The robot returns, the piston rod of the tension and retraction cylinder 15 extends out, and drives the second connecting rod 16, the third connecting rod 18 and the clamp cylinder mounting plate 19 to move through the third piston rod connector 17. The piston rod of the clamp cylinder 22 moves upward, and drives the fourth connecting rod 24 and the clamp rod 25 to move through the drive block 23, so that the clamp block 26 fixed at the lower end of the clamp rod 25 is close to the bag clamping mouth, clamps the two sides of the bag, and presses it against the narrow side plate 1.2. At this time, the matching packaging quantitative scale above puts the material into the bag. After the material is discharged, the piston rod of the clamp cylinder 3 retracts, the clamp 8 opens, the piston rod of the lifting cylinder 9 extends, the pneumatic clamp mechanism puts the packaging bag down, the piston rod of the tension and contraction cylinder 15 retracts, and the pneumatic clamp mechanisms on both sides of the bag clamping mouth move outward to straighten the bag mouth, and the clamp of the bag delivery trolley clamps the bag mouth under the pneumatic clamp mechanism. The piston rod of the clamp cylinder 22 moves downward, and drives the fourth connecting rod 24 and the clamp rod 25 to move through the driving block 23, so that the clamp block 26 fixed to the lower end of the clamp rod 25 opens, the piston rod of the lifting cylinder 9 retracts, and the pneumatic clamp mechanism returns to the high position. The entire workflow is completed.

[0039] The utility model adopts a fixed hexagonal bag clamp body 1, the clamp driving mechanism is installed on the wide side plate 1.1 of the bag clamp body 1, and the pneumatic clamp mechanism is symmetrically arranged on the left and right sides of the bag clamp body 1. The parallelogram of the pulling and retracting action (composed of the lifting mounting plate 11, the second connecting rod 16, the third connecting rod 18 and the clamp cylinder mounting plate 19) has a compact structure and is easy to install. The clamp 8 presses the long side of the bag opening on the wide side plate 1.1, and the inner end of the clamp block 26 is made into a chamfered bevel, such as Figure 6 As shown, the two sides of the bag opening are pressed on the narrow side plate 1.2, so that the entire bag opening is closed, and there is no worry about material leakage, especially for powdery materials, there is no need to worry about dust leaking from the two sides of the bag opening. The pneumatic clamp mechanism also has the functions of pulling and lifting, and is used in conjunction with the bagging manipulator and the bag feeding device, and the action is convenient and reliable.
