step four: the movable sleeve shaft 544 in the lifting and positioning component 54 is sleeved, the two ends of the shaft lever 523 are installed in the butt joint roller 522, and the cylinder 541 lifts to drive the positioning bracket 543 to ascend or descend, so as to drive the butt joint roller 522 to lift, so as to adjust the clamping degree of cutting between the butt joint roller 522 and the cutting roller 521, and facilitate the placement of materials to be cut;

step five: in cutting, both ends of the mounting shaft 523 in the cutting roller 521 are mounted in U-shaped mounting grooves 5241 in the abutting shaft 524, and bolts are mounted in fixing holes 5242 where the mounting shaft 523 and the mounting grooves 5241 overlap, whereby the cutting roller 521 and the mounting shaft 523 can be detached from the abutting shaft 524 even when not in use, and the cutting roller 521 can be replaced.

In summary, in the method for cutting pieces in a drum-type for a medical foldable mask, the upper ends of the fixed shaft levers 33 penetrate through the mounting frame plate 31, the guide motor 32 is installed at the upper end of one of the fixed shaft levers 33, the materials used for manufacturing the mask are placed into the guide rollers 34 for guiding, and can be placed into two groups in a one-time overlapping manner, the guide motor 32 drives the guide rollers 34 to rotate for guiding the materials, so as to improve the flatness of the materials and prevent wrinkles from appearing, thereby affecting the next round of operation, the cutting motor 531 drives the lower folding roller 43 to rotate through the connecting belt 533, embosses the surfaces of the two groups of materials after being folded, shapes the materials after being folded and embossed, thereby facilitating the subsequent cutting, the folding motor is connected with the mounting shaft lever 523 at the side end of the butt roller 522 through the belt, the two groups of materials after being embossed are placed into the cutting roller 521 and the butt roller 522, the cutting motor 531 drives, the folding and pressing motor drives the butt joint roller 522 to rotate, two groups of materials which are printed and pressed are cut, the materials are cut into the shape of the medical folding mask, two groups of cutting knife strips 5211 are arranged, the two groups of materials can be cut simultaneously, the cutting efficiency is improved, the production speed is increased, the production cost is reduced, the air cylinder 541 is lifted and lowered to drive the two ends of the positioning support 543 to ascend or descend in the penetrating groove 22, so that the butt joint roller 522 is driven to ascend and descend to adjust the pressing degree of cutting between the butt joint roller 522 and the cutting roller 521, the materials to be cut are convenient to place, the pressing degree between the butt joint roller 522 and the cutting roller 521 can be adjusted according to requirements, the adjustability in production is increased, the abrasion of the knife strips is reduced while the quality of products is guaranteed, the service life of the knife strips is prolonged, the installation shaft lever 523 is fixedly connected with the installation groove 5241 through bolts, the bolts are installed in the fixed holes 5242 where the installation shaft lever, when the cutting device is not used, the cutting roller 521 and the mounting shaft lever 523 can be detached from the butt joint shaft lever 524, the cutting roller 521 can be replaced, replacement and maintenance are facilitated, and poor products caused by aging and abrasion of blades are avoided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
