Description

Technical Field

[0001] The utility model relates to the technical field of calendering rolls, in particular to a calendering roll for metal calendering which is convenient for disassembly and assembly. Background Technique

[0002] Since the development of calender technology to date, various types and structures of equipment have been derived to meet different industrial application requirements. Calendering technology plays an important role in the field of polymer material processing. Not only is it an important processing and forming method for semi-finished and finished products of certain materials (such as rubber and thermoplastic plastics), but also through the calendering process, the material can be subjected to extrusion and stretching effects to become a thin sheet product with a certain thickness, width and smooth surface. The working principle of the calender is that through the shear force generated between the rollers, the material is repeatedly extruded and sheared, thereby increasing its plasticity and being extended into a thin product on the basis of further plasticization.

[0003] Most of the existing metal calendering rolls need to be maintained and replaced after long-term use. However, due to their complex structure and cumbersome disassembly and assembly process, a large amount of time and manpower are often required, which affects production efficiency. Therefore, we propose a calendering roll for metal calendering that is convenient for disassembly and assembly to solve this problem. Content of the Utility Model
