[0040] The working principle of the present scheme is as follows:

[0041] After the outer bag reaches the conveying platform 1, it is conveyed forward by the conveying belt mechanism installed on the rack, and when it reaches the end of the conveying platform 1, the baffle drive cylinder 21 of the baffle assembly 2 extends the piston rod downward, so that the vertical face of the L-shaped baffle 23 blocks the outer bag, and at the same time the conveying mechanism of the conveying platform 1 stops conveying, thus completing the positioning of the outer bag.

[0042] After the positioning of the outer bag is completed, the upper and lower suction disc assemblies 5 and 6 work simultaneously to adsorb the upper and lower surfaces of the bag body respectively, and then the upper suction disc cylinder 51 of the upper suction disc assembly 5 is lifted upward, thereby completing the opening action of the bag opening.

[0043] As shown, Figure 9 When the bag opening is opened, the rotating mechanism 71 of the rotating base assembly 7 is rotated by 90 degrees, so that the rotating arm 72 is inserted into the bag body, and the hole taking preparation action is completed. Then the head 33 of the head hole taking assembly 3 is driven downward by the head cylinder 31, and contacts the upper surface of the bag body, and under the action of the heating sawteeth, the hole is completed on the upper surface of the bag body.

[0044] After the hole is completed, the circular sheet material obtained by the hole is adhered to the sawtooth of the ironing head 33, when the ironing head 33 is lifted, the recovery pipe 42 of the waste recovery assembly 4 reaches the opening of the ironing head 33 under the push of the waste recovery cylinder 41, then the internal jet cavity 331 of the ironing head 33 sprays air outward, and the recovery pipe 42 inhales air inward, under the cooperation of the two, the circular sheet material after the hole is completed is inhaled into the recovery pipe 42, and then is conveyed to the air suction material collecting device through the conveying hose for collection.
