[0074] The working process of the M-bag feeding and waste cutting device of this embodiment is as follows:

[0075] In the first step, the bag-opening component 2 opens the bag opening 91 of the M bag 9 , and the material-feeding component 1 loads a plurality of stacked material trays into the M bag 9 .

[0076] In the second step, the transfer component 3 transfers the M bag 9 carrying several stacked material trays in an open state to the material receiving belt 4, and the transfer component 3 returns to its original position; specifically, in the process of transferring the M bag 9, the first suction cup 343 and the second suction cup 353 respectively adsorb the two sides of the outside of the bag opening 91 of the M bag 9, and the first vertical clamping plate 346 and the second vertical clamping plate 356 respectively clamp the two sides of the bag body 92 of the M bag 9 to ensure that the M bag is in an open state and stably transfer the M bag 9 to the material receiving belt 4; on the material receiving belt 4, in order to ensure that the M bag is in an open state, the third suction cup 572 and the fourth suction cup 582 approach each other and adsorb the two sides of the M bag 9 to make the M bag 9 in an open state, and the first movable plate 32 and the second movable plate 33 drive the first suction cup 343 and the second suction cup 353 to return to their original positions, and the open state of the M bag is ensured by the third suction cup 572 and the fourth suction cup 582 after the handover.

[0077] In the third step, the vacuum assembly 5 performs vacuuming on the M bag 9 placed on the receiving belt 4; specifically, the third lifting cylinder 51 drives the vacuum suction nozzle 54 to insert into the M bag 9 in the open state, the vacuum suction nozzle 54 is a flat and narrow rectangle, the first shaping plate 55 and the second shaping plate 56 are respectively located at the folding mark 95 of the M bag 9 in the open state, and are ready for bag folding; the fourth clamping finger cylinder 52 respectively drives the first shaping plate 55 and the second shaping plate 56 to approach each other and fold the M bag 9, and after folding, the third suction cup 572 and the fourth suction cup 582 return to their positions.

[0078] In the fourth step, the M bag 9 after the heat sealing assembly is evacuated is heat-sealed; specifically, the first telescopic cylinder 61 drives the first heat sealing assembly 62 to contact one side of the M bag 9, and the second telescopic cylinder 63 drives the second heat sealing assembly 64 to contact the other side of the M bag 9, and the vacuum suction nozzle 54 is sandwiched between the first foam cotton seal 623 and the second foam cotton seal 643. In order to press the vacuum suction nozzle 54 firmly, the first foam cotton seal 623 and the second foam cotton seal 643 will be deformed; the vacuum suction nozzle 54 starts to evacuate and evacuate the inside of the M bag 9 to a predetermined vacuum degree, such as a vacuum degree of 30%-70%, and the vacuum suction nozzle 54 is driven by the third lifting cylinder 51 to rise and withdraw from the M bag 9. During the withdrawal process, the first foam cotton seal 623 and the second foam cotton seal 643 will always press the bag opening 91; the first heat sealing assembly 62 and the second heat sealing assembly 64 are started to form a first heat seal 93 and a second heat seal 94 on both sides of the M bag, and the two heat seals can effectively prevent the occurrence of air leakage.

[0079] In the fifth step, the first clamping finger cylinder 37 clamps the waste edge 10 formed after the heat-sealed M bag, and the waste edge cutting component 7 cuts off the waste edge 10; specifically, when the first M bag is heat-sealed, the transfer component 3 has returned to its position and received the second M bag, and the transverse connecting plate 36 and the first clamping finger cylinder 37 are on one side of the first M bag. When the first clamping finger cylinder 37 clamps one side of the first M bag, the waste edge cutting component 7 moves along the top of the first heat sealing component 62 and completes the cutting of the waste edge 10.

[0080] In the sixth step, the transfer assembly 3 transfers the next M bag 9 carrying a plurality of stacked material trays to the material receiving belt 4 in an open state, and the waste edge 10 clamped by the first clamping finger cylinder 37 is transferred to the waste edge recovery assembly 8. Specifically, the next M bag 9 is the second M bag in the seventh step. When the second M bag is transferred to the material receiving belt 4, the transverse connecting plate 36 and the first clamping finger cylinder 37 are transferred to the top of the clamping finger 83. After the clamping finger 83 clamps the waste edge 10, the first clamping finger cylinder 37 releases the waste edge 10, so that the waste edge 10 is transferred to the clamping finger 83. After the transverse connecting plate 36 and the first clamping finger cylinder 37 return to their original positions, the telescopic cylinder 81 drives the clamping finger 83 to move to the top of the recovery container 85 through the mounting plate 82, and then releases the waste edge 10, which makes full use of the transfer process of the transfer assembly 3 and improves the efficiency of cutting waste edges of M bags.

[0087] Step S4: the M bag 9 after the heat sealing assembly is evacuated is heat-sealed; specifically, the first telescopic cylinder 61 drives the first heat sealing assembly 62 to contact one side of the M bag 9, and the second telescopic cylinder 63 drives the second heat sealing assembly 64 to contact the other side of the M bag 9, and the vacuum suction nozzle 54 is clamped between the first foam cotton seal 623 and the second foam cotton seal 643. In order to press the vacuum suction nozzle 54 firmly, the first foam cotton seal 623 and the second foam cotton seal 643 will be deformed; the vacuum suction nozzle 54 starts to evacuate and evacuates the inside of the M bag 9 to a predetermined vacuum degree, such as a vacuum degree of 30%-70%, and the vacuum suction nozzle 54 is driven to rise and withdraw from the M bag 9 by the third lifting cylinder 51. During the withdrawal process, the first foam cotton seal 623 and the second foam cotton seal 643 will always press the bag opening 91; the first heat sealing assembly 62 and the second heat sealing assembly 64 are started to form a first heat seal 93 and a second heat seal 94 on both sides of the M bag, and the two heat seals can effectively prevent the occurrence of air leakage.
