[0002] Papermaking industry plays an important role in modern society, with the progress of science and technology and the development of economy, the market for paper types and quality requirements are increasingly diversified. Different application scenarios, such as printing, packaging, writing, health and other fields, have strict and different requirements for the thickness of paper. From the very thin capacitor paper, cigarette paper to thicker cardboard, corrugated paper and other paper, papermaking enterprises need to be able to flexibly produce paper of various thickness specifications to meet market demand. The traditional papermaking roll is mostly fixed structure, and the distance between the rolls cannot be easily adjusted. This leads to the fact that when producing paper of different thickness, the pressure and gap between the rolls cannot be accurately controlled according to the ideal thickness of the paper. The installation and disassembly of traditional papermaking roll are often very complex. They are usually fixed on the papermaking machine through large bolts, welding or complex nested structure, which makes it a difficult task to disassemble the roll.
