[0109] The limiting plate 35 is fixed on the end surface of the transport frame 31 close to the base 341 .

[0110] A slot 350 is formed on one side of the limiting plate 35 close to the base 341 , and the slot 350 matches the shape of the buckle 346 .

[0111] By starting the motor 331, its output end drives the driving gear 333 to rotate through the commutator 332, and then drives the chain 1 to rotate through the meshing relationship. The chain 1 drives multiple driven gears 3211 to rotate in the same direction, thereby driving multiple rotating rods 321 to rotate in the same direction, which can be used to transport the completed packaging bags.

[0112] In some of the embodiments, the packaging bags are transported to the rod group 32 via a conveyor belt (not shown) or other equipment that can realize automatic transportation. If the packaging bags are directly transported to the multiple rotating rods 321 via a conveyor belt or other equipment that can realize automatic transportation, it is difficult to synchronize the packaging bags due to the speed difference between the conveying speed of the conveyor belt or other equipment that can realize automatic transportation and the rotating rods 321. As a result, the packaging bags will be deflected due to the speed difference when they are transported to the rotating rods 321, and the fully automatic bag stacking machine can generally only effectively stack packaging bags with the correct posture.

[0113] By setting the rotating rod 2 322 and the rotating rod 3 323, the length relationship of the rotating rod 1 321, the rotating rod 2 322 and the rotating rod 3 323 is that the rotating rod 1 321 is the longest, the rotating rod 2 322 is the second, and the rotating rod 3 323 is the shortest, and the rotating rod 3 323 is the shortest and is located at the outermost edge of the rod group 32. The rotating rod 2 322 is the closest to the outermost edge of the rod group 32 except the rotating rod 3 323. The rotating rod 1 321 is driven by the chain 1 to rotate synchronously, and the rotating rod 2 322 and the rotating rod 3 323 are only connected to the transport frame 31 by rotation.

[0114] In this case, when the packaging bag is transported to the rod group 32 by a conveyor belt (not shown) or other equipment capable of realizing automatic transportation, it will first be transported to the second rotating rod 322 and the third rotating rod 323. Since the second rotating rod 322 and the third rotating rod 323 are not driven by a driving device, the rotation of the two is a passive rotation caused by the push of the packaging bag. Therefore, the rotation speed is consistent with the transportation speed of the packaging bag. By synchronizing the speeds of the two, the deflection caused by the differential speed can be effectively eliminated. When the packaging bag is completely transported to the rod group 32, the first rotating rod 322 and the third rotating rod 323 are used to transport the packaging bag. 21 is rotated for conveying, the second rotating rod 322 and the third rotating rod 323 are passively rotated when the packaging bag is dragged, so the conveying speed remains consistent, until the packaging bag is conveyed outward from the rod group 32, the first rotating rod 321 rotates to convey the packaging bag to the other end of the rod group 32, and the second rotating rod 322 and the third rotating rod 323 at the other end are pushed by the packaging bag and passively rotated, so the conveying speed is also kept consistent. Similarly, when the packaging bag is conveyed from the rod group 32 to other equipment that can realize automatic conveying, the same speed conveying can also be maintained.

[0115] By starting the second motor 342, it drives the second driving gear 344 to rotate through the second commutator 343, and the second driving gear 344 drives the turntable 345 to rotate through the meshing relationship. The turntable 345 drives the entire transport frame 31 and the rod group 32 and the driving assembly 33 on the transport frame 31 to rotate. The angle of the rod group 32 can be adjusted in this way.

[0116] By adjusting the angle of the rod group 32, the following two beneficial effects can be achieved:

[0117] First, when the packaging bag is transported to the rod group 32 by a conveyor belt or other equipment that can realize automatic transportation, if the conveyor belt or other equipment that can realize automatic transportation is not aligned with the rod group 32, the two can be aligned by adjusting the angle of the rod group 32. After the packaging bag is transported to the rod group 32, the angle of the rod group 32 is adjusted again to restore it, and the packaging bag can be transported at the correct angle. Even if the conveyor belt or other equipment that can realize automatic transportation is not aligned with the rod group 32, the packaging bag can be effectively transported. Similarly, when the packaging bag is transported from the rod group 32 to the conveyor belt or other equipment that can realize automatic transportation, if the two are not aligned, the angle of the rod group 32 can also be adjusted to achieve effective transportation of the packaging bag.

[0118] Secondly, in some special cases, the packaging bags are not stacked in a head-to-tail alignment manner, but need to be stacked in a horizontally and vertically alternating manner or other non-head-to-tail alignment manner to increase the stability of the stacking. Taking the horizontally and vertically alternating manner as an example, after the first packaging bag is transported to the rod group 32, it is lifted up by the bag lifting device 2 in a normal posture. After the second packaging bag is transported to the rod group 32, the angle of the rod group 32 is adjusted to rotate 90°. When the bag lifting device 2 falls back, the packaging bag lifted on it falls on the packaging bag on the rod group 32, and the two are alternately stacked horizontally and vertically. Then the angle of the rod group 32 is adjusted to rotate 90°, and the bag lifting device 2 lifts the two horizontally and vertically alternating packaging bags, and then the next packaging bag is transported to the rod group 32. By analogy, it is possible to stack the packaging bags in a horizontally and vertically alternating manner or other non-head-to-tail alignment manner.

[0119] By starting motor three 111, motor three 111 drives connecting rod three 122 to rotate through commutator three 112, connecting rod three 122 drives connecting rod four 123 to rotate through commutator four 121, connecting rod four 123 drives driving gear three 137 to rotate, driving gear three 137 drives chain two to rotate, chain two drives slider one 134 to move on slide rail one 133, and slide rail one 133 drives the entire bag lifting device 2 to move up and down through connecting rod one 135.

[0120] It can be understood that when the bag lifting device 2 moves downward, and the cylinder 1 222 is connected to an independent high-pressure air pump (not shown), the output end of the cylinder 1 222 is controlled by the high-pressure air pump to extend, so that the lifting plate 223 can be pushed to move downward, and the rotating wheels 2232 on both sides of the lifting plate 223 are restricted by the vertical groove 1 2241, the vertical groove 2242 and the arc groove 2243, so that the lifting plate 223 will deflect to the side where the vertical groove 1 2241 is located while moving downward, so that the packaging bag on the rod group 32 can be lifted, and then the bag lifting device 2 can be controlled to move upward. , the packaging bag can be moved upward. After the next packaging bag is transported to the rod group 32, the bag lifting device 2 is controlled to move downward, the output end of the control cylinder 222 is retracted, the lifting plate 223 is reset, and the previously lifted packaging bag falls back to the top of the packaging bag on the rod group 32, and then the output end of the control cylinder 222 is extended again to lift the two packaging bags at the same time, and the bag lifting device 2 is controlled to move upward, so that both packaging bags can be moved upward, and so on, until the number of stacked packaging bags is consistent with the number of packaging bags required for stacking, the stack will be transported outward by the rod group 32.

[0121] It can be understood that by connecting cylinder 241 to an independent high-pressure air pump, and controlling the output end of cylinder 241 to extend through the high-pressure air pump, the push plate 243 can be driven to move. The push plate 243 drives the baffle 245 to move around the packaging bag through the mounting frame 244 to block the packaging bag and prevent the packaging bag from falling when it is lifted by the lifting plate 223.

[0122] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the scope of the present invention through the above description. The technical scope of this invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
