[0040] The specific implementation method is as follows: by setting up a stacking clamp mechanism 6, the second electric push rod 605 push rod drives the pressure plate frame 602 to move, so that the pressure plate frame 602 moves down and contacts the top of the paper bag, and the second electric push rod 605 continuously drives the pressure plate frame 602 to move, so that the pressure plate frame 602 fixes the paper bag to prevent the upper paper bag from falling due to wind during the transportation process, thereby ensuring that the paper bag is more stable during transportation, and by setting up a first electric push rod 603, the first electric push rod 603 push rod drives the connecting frame 606 to move, and then the connecting frame 606 drives the supporting plate 604 to move, so that when the stacked paper bags are stacked, the supporting plate 604 slides out, thereby avoiding the need for manual picking, thereby improving work efficiency, and by setting up an adjusting device 9, by rotating the bottom plate 902, the bottom plate 902 drives the adjusting ring 901 to rotate, so that the adjusting ring 901 moves through the internal nut, and then the first support frame 3 is leveled to ensure the horizontality of the device operation.

[0041] One of the stacking mechanisms 8 is located at the top of the second conveying mechanism 5 and is lower than the first conveying mechanism 4, and the other stacking mechanism 8 is located at the side of the second conveying mechanism 5 and is lower than the second conveying mechanism 5.

[0042] The specific implementation method is as follows: by setting a stacking mechanism 8, when the conveyor belt 403 drives the paper bag to move and fall to the top of the bottom frame 807, a baffle plate 808 is set to block the paper bag from sliding out of the bottom frame 807 due to inertia, thereby preventing the paper bag from being wasted. In addition, the guide plate 801 is used to guide the paper bag to fall accurately and drive the top of the bottom frame 807, and then the third electric push rod 812 drives the moving plate 809 to move, so that the moving plate 809 drives the screed plate 802 to move, so that the screed plate 802 squeezes the paper bag. The paper bags are pressed and leveled to keep the stack neat, making it more convenient to transfer them later. The sliding rod 811 is arranged and driven by the movable plate 809 to slide in the sliding sleeve.

Therefore, the device can adjust the leveling area according to the size of the paper bags, thereby ensuring the scope of application of the device.

[0043] Working principle: When in use, the paper bags are conveyed to the stacking mechanism 8 via the conveyor belt 403 of the first conveying mechanism 4. When the stacking mechanism 8 of the upper layer is stacked to the required thickness, the push rod of the cylinder 11 drives one side of the fixed frame 402 in the first conveying mechanism 4 to move, so that the fixed frame 402 drives the conveyor belt 403 to change the conveying direction, and then the subsequent paper bags are conveyed to the stacking mechanism 8 of the lower layer via the second conveying mechanism 5, so that the device can transfer the paper bag pile without stopping. When the paper bag falls to the top of the bottom frame 807, the push rod of the third electric push rod 812 drives the moving plate 809 to move , so that the movable plate 809 drives the leveling plate 802 to move, and then the leveling plate 802 levels the paper bags for subsequent transportation. Finally, the robot arm 1 drives the connecting rod 611 to move through the connecting plate 2, so that the connecting rod 611 drives the second support frame 609 to move, and then the second support frame 609 drives the connecting frame 606 to move, so that the connecting frame 606 drives the supporting plate 604 to move and plug into the bottom of the paper bag pile, and then drives the pressing plate frame 602 to move through the second electric push rod 605, so that the pressing plate frame 602 squeezes the paper bag pile to prevent the upper paper bags from falling when the paper bag pile is transported.

10. The method for using the paper bag forming, conveying and stacking machine is characterized in that: The paper bag forming, conveying and stacking machine used in any one of claims 1 to 9 specifically comprises the following steps: The output end of the driving unit (407) drives the second rotating rod (406) to rotate, thereby causing the second rotating rod (406) to drive the transmission wheel (405) to rotate, and the second transmission wheel (405) drives the conveyor belt (403) to rotate, so that the conveyor belt (403) drives the paper bags to be transported to the upper stacking mechanism (8). When the upper stacking mechanism (8) reaches the required thickness, the top rod of the cylinder (11) drives the fixed frame (402) in the first conveying mechanism (4) to move, so that the fixed frame (402) rotates through the first fixed plate (7), thereby causing one side of the first conveying mechanism (4) to be flush with one side of the second conveying mechanism (5), so that the paper bags are transported to the lower stacking mechanism (8) through the second conveying mechanism (5), so that the machine does not need to be stopped when the stacked paper bags are transported, thereby ensuring work efficiency.
