When the stacking height of large-sized packaging bags is high, the situation that the middle concave is arched on both sides (such as Fig.13 As shown in the figure, the top plate of the bag warehouse will be lifted up to level the packaging bags. Fig.14 As shown, in order to cope with and solve the problem and improve the success rate of bag retrieval, when the height of the packaging bag is reduced to a certain height, the top plate of the bag warehouse will retract to avoid the situation where the middle is convex and the two sides collapse.

[0052] In this embodiment, a driving mechanism 150 for driving the movement of the bag storage centering plate is provided below the bag placing plate, a clearance slot is provided on the bag placing plate for the bag storage centering plate to pass downward, and sliding seats 160 that can be synchronously moved toward or away from each other by the driving mechanism are provided on the left and right sides of the bottom of the bag placing plate, and the lower part of the bag storage centering plate is connected to the sliding seat on the same side.

[0053] In this embodiment, the driving mechanism 150 includes a transverse screw 151 arranged along the left and right directions, and the left and right sections of the transverse screw are provided with threaded sections with opposite rotation directions.

[0054] In this embodiment, a lifting cylinder 170 for driving the top plate of the bag storage to rise and fall and a detection sensor 180 for sensing the packaging bags are installed at the bottom of the bag placing plate. A clearance hole is provided above the lifting cylinder and the detection sensor on the bag placing plate. When the detection sensor detects that the packaging bags are used up, it will prompt that the packaging bags are used up and stop the further action.

[0055] A working method of the automatic bagging machine as described above comprises the following steps: (1) a worker stacks packaging bags and places them on a bag storage mechanism; (2) a bag picking and moving mechanism transfers the packaging bags in the bag storage mechanism and places them in a bag feeding and centering mechanism; (3) the bag feeding and centering mechanism transports the packaging bags forward and performs centering and deviation correction processing; (4) a bag baffle plate at the front end of the bag feeding and centering mechanism rises to stop the packaging bags at a suitable position, and an upper bag opening cylinder and a lower bag opening cylinder cooperate to open the bag mouth of the packaging bags; (5) a swing arm mechanism puts the packaging bags on a shaping machine.

[0056] The specific process of step (1) is as follows: the front end of the packaging bag is blocked by the front baffle of the bag library, and the packaging bag is centered by the centering plates of the bag library on both sides. The packaging bags are stacked neatly by using the centering plates and the front baffle of the bag library. When the height of the large-sized packaging bags is high, the concave middle and the arched sides are more obvious. At this time, the top plate of the bag library will be lifted up to flatten the packaging bag, thereby improving the success rate of bag retrieval.

[0057] The specific process of step (2) is as follows: the lifting cylinder receives a signal, descends to the position and absorbs the packaging bag through the vacuum suction cup. After the detection signal detects that the bag is successfully taken, the packaging bag will be raised to a suitable position, and the packaging bag will be placed in the bag delivery centering mechanism by moving the cylinder forward for the next step of judgment. After the detection signal detects that the bag is placed, it will move backward and repeat the bag taking action; if the detection signal detects that the bag taking fails, the bag taking action will be repeated until the bag is successfully taken.

[0058] The specific process of step (3) is as follows: the conveyor belt rotates forward to convey the packaging bag forward to the front end of the conveyor belt. When the packaging bag reaches the middle of the brush mounting plates on both sides, the brush mounting plates on both sides move toward the middle, and the brushes on the lower sides of the brush mounting plates are used to perform centering and deviation correction on the packaging bag.

[0059] The specific process of step (4) is as follows: the bag-stopping cylinder extends, and the bag-stopping plate is used to stop the packaging bag at a suitable position to prepare for the bag-opening action; the upper bag-opening cylinder and the lower bag-opening cylinder extend, and the suction cup on the upper bag-opening cylinder sucks the upper side of the packaging bag, and the suction cup on the lower bag-opening cylinder sucks the lower side of the packaging bag, and then the upper bag-opening cylinder and the lower bag-opening cylinder contract to complete the bag-opening action, and then the bag-stopping cylinder contracts and the bag-stopping plate descends;

[0060] The specific process of step (5) is as follows: when the packaging bag is in the bag-opening state, the swing arm of the swing arm mechanism swings down into position along with the upper bag rotating shaft, and then the two swing arm mounting plates move away from each other to complete the bag-opening operation, and then the suction cups on the upper and lower bag-opening cylinders are released, and the swing arm swings up into position along with the upper bag rotating shaft, and the packaging bag is put onto the shaping machine for subsequent shaping operations.

[0061] The automatic bagging machine of the present invention can automatically bag four six-sided vacuum bags at the same time. The bag taking method is that multiple vacuum suction cups perform targeted vacuum absorption according to the size of the bags. The method is more stable and compatible with bags of various specifications. The bag feeding and centering mechanism is used to correct the placement of the bags and improve the success rate of bag loading. The bag opening mechanism can adjust the opening size according to the packaging specifications of the bags. The swing arm mechanism adopts a rotating plunger for positioning, which can quickly and accurately adjust the swing arm bag width into place. The bagging machine can move forward and backward, which not only provides convenience for employees to operate and debug, but also facilitates later maintenance and repair.
