[0053] The working principle of the present invention is as follows:

[0054] Before packaging, the operator first places the packaging bag into the storage unit 11 in the feeding module 1 .

[0055] During packaging, the transfer unit 33 moves to the storage unit 11 in the feeding module 1 through the transfer drive slide rail 32, and the piston rod of the electric push cylinder 332 extends to drive the transfer fixed plate 335 to move downward. At this time, the third suction cup 440 indirectly connected to the transfer fixed plate 335 through the first transfer bracket 336, the second transfer bracket 337, the third transfer bracket 338 and the fourth transfer bracket 339 moves downward together to suck up the packaging bag. After sucking it up, the piston rod of the electric push cylinder 332 retracts to lift the sucked packaging bag.

[0056] Then, the transfer unit 33 moves to the bag opening unit 22 in the bag opening module 2 through the transfer drive slide rail 32, and the piston rod of the electric push cylinder 332 extends to drive the transfer fixing plate 335 to move downward, and the packaging bag sucked up by the third suction cup 440 follows and descends; after descending to a certain height, the second suction cup 226 sucks one side of the bag opening of the packaging bag. At this time, the piston rod of the bag pressing cylinder 442 extends to drive the pressure rod 443 on it to descend, pressing the bag opening of the packaging bag downward and disengaging it from the third suction cup 440 in the first transfer bracket 336; then, the piston rod of the bag pressing cylinder 441 extends to drive the pressure rod 443 on it to descend, disengaging the middle and rear part of the packaging bag from the second transfer bracket 337, the third transfer bracket 338 and the third suction cup 440 in the fourth transfer bracket 339, and pressing it down into the bag opening fixing frame 221 and the bag opening. The gap between the brackets 223; then, the piston rod of the electric push cylinder 332 retracts, so that the third suction cup 440 is away from the packaging bag. After lifting a certain high end, the piston rods of the bag pressing cylinder 442 and the bag pressing cylinder 441 retract. At the same time, the bag opening rotating cylinder 225 drives the bag opening bracket 223 to rotate 90 degrees. At this time, the second suction cup 226 changes from a horizontal state to a vertical state, opposite to the first suction cup 222; then, the bag opening rodless cylinder 224 drives the bag opening rotating cylinder 225 to move, so that the second suction cup 226 approaches the first suction cup 222, so that the first suction cup 222 sucks the other side of the bag opening of the packaging bag. After sucking, the bag opening rodless cylinder 224 drives the bag opening rotating cylinder 225 to move in the opposite direction, so that the second suction cup 226 is away from the first suction cup 222, thereby opening the bag opening of the packaging bag.

[0057] Then, the robot arm 51 in the bagging module 5 drives the bag clamping unit 52 to move to the bag opening unit 22, and moves toward the bag with the bag opening opened, so that the clamping claw of the first clamping claw cylinder 522 drives the clamping plate 523 to clamp the bag opening of the bag (such as Figure 15 As shown); then, the robotic arm 51 drives the packaging bag clamping claw unit 52 holding the packaging bag to move to the material box return unit 42.

[0058] Then, the speed chain unit 41 drives the magazine assembly 43 to move to the pressing cylinder 424 in the magazine return unit 42. Subsequently, the piston rod of the pressing cylinder 424 extends to drive the pressing plate 425 and presses the first folding plate 434 and the second folding plate 43 on the left and right sides of the upper end of the magazine 432, so that the first folding plate 434 and the second folding plate 43 are folded along the first hinge 433 to the outside of the magazine 432. After completion, the speed chain unit 41 drives the magazine assembly 43 to move to the folding ear Component 421, and the robot arm 51 drives the packaging bag clamping claw unit 52 with the packaging bag to move above the material box 432; then, the piston rod of the clamping claw lifting cylinder 524 extends, and drives the expansion roller 529 to descend to the bottom of the packaging bag through the clamping claw connecting plate 530, the second clamping claw cylinder 527 and the core shaft connecting piece 528; then, the clamping claw of the second clamping claw cylinder 527 drives the two sets of expansion rollers 529 to expand through the core shaft connecting piece 528, so as to realize the expansion of the bottom of the packaging bag (such as Figure 16 434, and the second folding plate 436 on the corresponding side is folded 90 degrees to the inner side of the first folding plate 434. The stacking plate 436 presses the mouth of the packaging bag; then, the piston rod of the ear folding lifting cylinder 4215 extends out, and after lifting the ear folding roller 4213 on the corresponding side, the piston rod of the double-rod cylinder 4212 contracts, driving the ear folding roller 4213 on the corresponding side to retract, and then the clamping jaws of the second clamping cylinder 527 close, driving the two sets of stretching rollers 529 to close, and then the piston rod of the clamping jaw lifting cylinder 524 retracts, so that the stretching roller 529 is separated from the packaging bag; finally, the material box assembly 43 flows to the next workstation through the double-speed chain unit 41.

[0059] It should be noted here that when the packaging bags in one group of storage units 11 are taken out, they will automatically be transferred to other storage units 11 to continue taking packaging bags, and the storage unit 11 that has run out of packaging bags will sound an alarm, and the operator can come to place the packaging bags, and there is no need for special personnel to guard, which frees up manpower; secondly, in each group of storage units 11, after 10 packaging bags are taken out, there will be a partition. At this time, the transfer module 3 will first transfer the partition to the partition receiving unit 23 in the bag opening module 2, and then transfer the packaging bags; and after each packaging bag is taken out, the lifting unit 12 will lift the other packaging bags in the storage unit 11 to a corresponding height to facilitate the next time the transfer module 3 takes material.

[0060] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
