The specific implementation process is as follows:

the stripped sanitary towel semi-finished product is sent to the gap between the anvil roller 3 and the knife roller 11, the motor drives the knife roller 11 to rotate clockwise, the knife roller 11 drives the anvil roller 3 to rotate anticlockwise through friction, and therefore the sanitary towel semi-finished product is conveyed outwards. When the knife roller 11 rotates, the knife 12 contacts with the semi-finished product of the sanitary towel to cut the shape of the sanitary towel to form a product. Through the external getter device of gas connection 20 during the cutting, distribution disc 13 does not rotate when rotor 11 rotates, and air flue 9 on rotor 11 rotates to 8 intercommunications with the gas groove on distribution disc 13 during the cutting, and getter device passes through gas groove 8, air flue 9 and gas pocket 10 and adsorbs the product on rotor 11 for more level and smooth of product cutting. After cutting, the knife roller 11 rotates until the air channel 9 is staggered with the air groove 8, products are not adsorbed by the knife roller 11, the products are absorbed by the conveying drum, and then the products are transferred to the conveying belt to be conveyed away. Meanwhile, the waste materials are sucked by the conveying drum and conveyed to a subsequent processing device for processing.

The anvil roll 3 is cleaned by rubbing its roll surface against the wiping member 14 during rotation of the anvil roll 3. In the same way, in the rotating process of the knife roller 11, the knife 12 rubs against the cleaning ring 17, and the cleaning ring 17 cleans the knife 12; the guard circle of rotor 11 rubs with guard circle clearance piece 21, realizes the clearance of guard circle, through clearing up anvil roller 3, cutter 12 and guard circle, can effectually avoid impurity to carry the product on.

When the gap between the knife roll 11 and the anvil roll 3 needs to be adjusted, the adjusting screw 16 is rotated, the adjusting screw 16 drives the adjusting inclined block 19 to move, and the inclined surface of the adjusting inclined block 19 cooperates with the inclined surface of the bearing 6 on the anvil roll 3 to enable the bearing 6 to move upwards or downwards, so that the gap between the anvil roll 3 and the knife roll 11 is adjusted.

In the embodiment, the knife roll 11 drives the anvil roll 3 to rotate through friction, and compared with the prior art in which gear driving is adopted, the problem that gears are not suitable and need to be replaced after the anvil roll 3 is worn does not need to be worried about; in addition, because the problem of gear engagement is avoided, the impression of the knife roll 11 on the anvil roll 3 is not always in the same position, thereby effectively reducing the abrasion of the anvil roll 3 and prolonging the service life of the anvil roll 3. In the cutting process, the anvil roller 3 is pressed on the knife roller 11 through the air cylinder 4 and the self gravity, the air cylinder 4 does not need to provide large air pressure, the efficiency and resources are saved, and the service lives of the anvil roller 3 and the knife roller 11 are prolonged.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein.
