Thus, when the pneumatic cylinder drives the clamping blocks to extend and move towards each other and abut against each other, the opening 141 is closed at this time, and the storage hopper 12 and the bagging cylinder 11 are not communicated; when the pneumatic cylinder drives the clamping blocks to retract and move away from each other by a distance, the opening 141 is opened at this time, and the storage hopper 12 and the bagging cylinder 11 are communicated to realize the material falling.

[0055] Referring to Figures 5-6 The plug plate air extraction assembly 21 of the top box mechanism 2 comprises a first box body 211, a plurality of plug plate air extraction modules arranged on the first box body 211, and an opening and closing driving module 213 arranged on the first box body 211 and used for driving the plug plate air extraction modules to act; specifically, the plug plate air extraction module comprises two fixed plug plates 2121 arranged at intervals left and right, two movable plug plates 2122 arranged at intervals left and right and capable of moving left and right, and an air extraction pipe 2123 arranged between the two fixed plug plates 2121; the opening and closing driving module 213 is used for driving the two movable plug plates 2122 to move towards or away from each other in the left and right directions; wherein the fixed plug plate 2121 comprises two plug plate units arranged at intervals front and back, and a gap exists between the two plug plate units, and the opening and closing driving module 213 can drive the movable plug plate 2122 to move left and right and pass through the gap to realize the folding angle of the bag opening of the packaging bag 5; the air extraction pipe 2123 is used for vacuumizing the packaging bag 5.

[0056] In addition, a lifting driving module 214 is further arranged at both ends of the first box body 211, and the lifting driving module 214 is used for driving the first box body 211 to lift relative to the shoulder pressing and sealing assembly 22. Wherein, the shoulder pressing and sealing assembly 22 comprises a second box body 221, and the lifting driving module 214 is a pneumatic cylinder, the cylinder body of the pneumatic cylinder is installed at the end of the first box body 211, and the piston rod of the pneumatic cylinder is connected with the second box body 221; thus, when the piston rod of the pneumatic cylinder extends or retracts, the plug plate air extraction assembly 21 can be driven to lift relative to the shoulder pressing and sealing assembly 22.

[0057] In addition, the shoulder pressing and sealing assembly 22 further comprises a shoulder pressing module 222 and a sealing module 223 arranged on the second box body 221. Specifically, the shoulder pressing module 222 comprises two pressing blocks 2221 arranged in front and back directions and a first driving assembly for driving the two pressing blocks 2221 to move towards or away from each other in the front and back directions.

Preferably, the first driving assembly is a first air cylinder 2222, and the second driving assembly is a second air cylinder 2232.

[0058] Therefore, the working process of the top box mechanism 2 is as follows: first, as shown in Figure 5 , the opening and closing driving module 213 drives the two movable insertion plates 2122 to move away from each other to be in an open state, and at the same time, the shoulder pressing module 222 and the sealing module 223 are also in an open state. At this time, the insertion plate vacuumizing assembly 21 is lowered by the lifting driving module 214 to make the fixed insertion plate 2121, the movable insertion plate 2122 and the vacuumizing pipe 2123 inserted into the packaging bag 5; then, the opening and closing driving module 213 drives the two movable insertion plates 2122 to move towards each other and pass through the gap between the two insertion plate units to fold out the bag opening corner, as shown in Figure 7 ; subsequently, the shoulder pressing module 222 is actuated to make the two pressing blocks 2221 move towards each other and press and seal the bag opening of the packaging bag 5, and then the vacuumizing pipe 2123 starts to vacuumize, as shown in Figure 8 ; after the vacuumizing is completed, the insertion plate vacuumizing assembly 21 is raised by the lifting driving module 214, at this time, the fixed insertion plate 2121, the movable insertion plate 2122 and the vacuumizing pipe 2123 are all separated from the packaging bag 5, at this time, the sealing module 223 is actuated to make the two heating bodies 2231 move towards each other and heat seal the bag opening of the packaging bag 5, as shown in Figure 9 ; after the heat sealing is completed, the sealing module 223 is actuated to make the two heating bodies 2231 move away from each other to be separated from the packaging bag 5, at this time, the shoulder pressing module 222 is still in a closed state and clamps the finished product of the packaging bag 5, as shown in Figure 10 ; finally, after the conveying belt 43 moves below the top box mechanism 2, the shoulder pressing module 222 of the top box mechanism 2 is opened to make the finished product of the packaging bag 5 fall onto the conveying belt 43, and then the finished product of the packaging bag 5 is conveyed to the next station by the conveying belt 43, thus completing one cycle.

[0059] Referring to Figures 11-13The bidirectional lifting mechanism 3 further comprises a transmission shaft assembly, a driving assembly and a wheel belt transmission assembly. The transmission shaft assembly comprises an upper transmission shaft 34 and a lower transmission shaft 35 arranged in an upper-lower interval, both ends of the upper transmission shaft 34 and both ends of the lower transmission shaft 35 are respectively penetrated in the two supports 31. The driving assembly comprises a first driving device 36 and a second driving device 37 arranged in an upper-lower interval, the first driving device 36 is used for driving the upper transmission shaft 34 to rotate, and the second driving device 37 is used for driving the lower transmission shaft 35 to rotate. Preferably, the first driving device 36 and the second driving device 37 are both speed reduction motors. The wheel belt transmission assembly comprises a first wheel belt transmission module 38 and a second wheel belt transmission module 39 arranged between the upper transmission shaft 34 and the lower transmission shaft 35, the first wheel belt transmission module 38 is connected with the two first hanging arms 32, and the second wheel belt transmission module 39 is connected with the two second hanging arms 33.

[0060] Further, the first wheel belt transmission module 38 comprises a first driving wheel 381 fixedly sleeved on the upper transmission shaft 34, a first driven wheel 382 rotatably sleeved on the lower transmission shaft 35, and a first transmission strip 383 wound on the first driving wheel 381 and the first driven wheel 382 respectively, the first transmission strip 383 is connected with the first hanging arm 32; the second wheel belt transmission module 39 comprises a second driving wheel 391 fixedly sleeved on the lower transmission shaft 35, a second driven wheel 392 rotatably sleeved on the upper transmission shaft 34, and a second transmission strip 393 wound on the second driving wheel 391 and the second driven wheel 392 respectively; the second transmission strip 393 is connected with the second hanging arm 33.

[0061] Therefore, when the first driving device 36 drives the upper transmission shaft 34 to rotate, at this time the upper transmission shaft 34 is the driving shaft and the lower transmission shaft 35 is the fixed shaft, under the action of the first wheel belt transmission module 38, the first hanging arm 32 can be driven to move up and down; when the second driving device 37 drives the lower transmission shaft 35 to rotate, at this time the lower transmission shaft 35 is the driving shaft and the upper transmission shaft 34 is the fixed shaft, under the action of the second wheel belt transmission module 39, the second hanging arm 33 can be driven to move up and down. Therefore, by using the bidirectional lifting mechanism 3 of the present application, the originally two independent transmission shaft assemblies become one shared transmission shaft assembly, the device can greatly reduce the space occupied without interfering with each other, and the number of parts is also reduced, thereby reducing the cost.

[0062] Preferably, the first wheel belt transmission module 38 and the second wheel belt transmission module 39 are each provided with two groups and are arranged on the left and right ends of the transmission shaft assembly. Therefore, by arranging two groups of the first wheel belt transmission module 38 and two groups of the second wheel belt transmission module 39, the structure is more balanced and stable, thereby improving the lifting movement reliability of the bidirectional lifting device.
