[0033] Working principle: Before using this cutting device for packaging bag production with pressing function, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, as the automatic cutting machine 102 continues to cut, before the cutter of the automatic cutting machine 102 descends, the electric shaft 202 will rotate the disc 203, so that the circular groove 204 drives the connecting rod 206 to rise and fall, and then the pressing plate 207 descends.
