Through detachable outer ring 42 and detachable fixed block 75 convenient with cutting knife 43 fixed mounting on rotating body 41, but also can be after cutting knife 43 long-term work wearing and tearing, can be so that change new cutting knife 43 through dismantling outer ring 42 and fixed block 75. The cutting knife 43 can be a plurality of, and each cutting knife 43 is all installed on the rotating main body 41 through the crimping of fixed block 75, and a plurality of cutting knives 43 evenly set up on the rotating main body 41 along the circumferencial direction, can cut off the bridge of the nose strip that obtains required length between every two adjacent cutting knives 43, and the quantity of the cutting knife 43 on the cutter roller 4 designs according to the cutting length of bridge of the nose strip.

More specifically, referring to fig. 9, the outer ring 42 is composed of a plurality of circular arc ring blocks, each circular arc ring block is detachably connected to the rotating body 41 through a bolt, and a cutting opening for exposing the cutting knife 43 is formed between two adjacent circular arc ring blocks; referring to fig. 10, the adjusting hole 441 is an oblong hole, and the fixing hole of the rotating body 41 is a common circular hole, so that the adjusting hole 441 is convenient to be displaced left and right when the mounting block 44 is mounted on the rotating body 41, so as to adjust the length of the cutting blade 43 exposed out of the entire cutter roller 4, and the cutting blade 43 has a proper cutting depth to cut off the nose bridge. In addition, referring to fig. 11, a bearing seat 81 is installed on the moving base plate 2, the bearing seat 81 is rotatably connected with the rotating shaft of the cutter roller 4 through an inner bearing 82, a synchronizing wheel 83 is installed at the other end of the rotating shaft of the cutter roller 4, the synchronizing wheel 83 can be in transmission connection with the output shaft of the cutter roller 4 through a belt, the synchronizing wheel 83 can also be in meshing connection with a gear on the output shaft of a power device, and the transmission connection between the whole cutter roller 4 and the power device can be released.

The specific processing steps of this example are:

referring to fig. 12, the processing direction of the nose bridge strip is AB direction in fig. 12, the nose bridge strip firstly enters the whole device through the nose bridge strip limiting inlet mechanism 9, passes through the guide gap between the first guide wheel 61 and the second guide wheel 62 to guide the nose bridge strip to be conveyed in the corresponding direction, then the feeding of the nose bridge strip is stabilized through the first limiting part 63, and then the nose bridge strip passes through the flattening gap between the first flattening roller 64 and the second flattening roller 65 so as to provide the power for the forward conveying of the nose bridge strip, and under the guiding action of the second limiting part 66, the cutting position of the nose bridge strip is smoothly conveyed to the cutter roller 4, the cutting operation of the nose bridge strip is completed in the cutting gap formed by the cutter roller 4 and the cutter anvil 5, then the cut nose bridge strip is pressed on the material wrapping plate 71 by the compaction roller 72, so that the cut nose bridge strip and the non-woven fabric material are combined together to complete the installation of the nose bridge strip in the mask.
