Description

Preparation process of cutter roller Technical Field The invention relates to a preparation process of a cutter roller. Background In the production process of sanitary articles such as diapers, a roll cutting device is an indispensable device mainly used for cutting continuously conveyed materials such as nonwoven fabrics, absorbent cores, etc. at a high speed according to a predetermined shape and size. The conventional roll cutting device generally comprises a cutter roller and a bottom roller which are matched with each other, wherein a cutter is arranged on the cutter roller, and a shearing action is realized through relative rotation of the cutter roller and the bottom roller. However, conventional cutter rolls are often manufactured by integral machining or integral heat treatment, and expensive high-hardness alloy steels are often required for the whole roll body in order to ensure the hardness and wear resistance of the cutter. The cutter and the roller body are in an integrated structure or fixed and not detachable when the cutter is worn or broken, so that the whole cutter roller is often required to be replaced, the downtime is increased, and the maintenance cost is greatly increased. Disclosure of Invention Therefore, in order to solve the above problems, the present invention provides a process for manufacturing a cutter roller, which can reduce the production cost, is convenient to maintain, and can flexibly match the performances of different materials.
