At present, pollution-free paper machines are very popular in the paper machine industry. The reason is that environmental protection awareness has increased and polluting equipment has been gradually eliminated.

Paper is inferior to imported paper in terms of pulling strength, so my country is a big paper-making country, not a strong paper-making country.

After the paper sheet from the drying section is calendered by the calender, the smoothness, gloss and tightness of the paper sheet can be improved, the thickness of the whole paper sheet can be consistent, and the air permeability can be reduced; Rolling into a paper roll completes the main process of papermaking. In order to meet different needs in the future, there are also calenders, rewinders, paper cutters, etc. after the paper roll in the papermaking equipment workshop.

The modern paper machine industry has developed to this day, how to quickly realize energy saving and consumption reduction in production is one of the necessary ways for the development of the paper machine industry. The production of paper machine equipment can implement advanced key technologies and equipment by improving the structure of each operating unit, thereby realizing energy saving and reducing consumption, and ensuring the stable and rapid development of the paper machine industry.

The vibration of the paper machine, especially the high-speed paper machine press roll, is a headache and dangerous thing. The vibration of the press roll will inevitably lead to uneven dehydration of the paper in the press section, which will easily cause frequent paper breaks. Excessive vibration will limit the speed of the paper machine. If it causes resonance, it will directly affect the structural stability of the entire paper machine; Vibration will also produce harsh noise.
