Modern paper-making machinery can be said to be a behemoth with a high degree of integration. Its width can reach 10m, height can reach 20m, and length can even reach 150m. Each papermaking machine includes at least four main parts: forming part or wire part, press part, drying part, rewinding part

At present, the technologies for fault diagnosis and maintenance of paper machines mainly include oil analysis technology and vibration monitoring technology. Vibration monitoring technology mainly uses vibration signals to perform condition monitoring and fault diagnosis of paper machines.

The main body of the paper machine and its auxiliary and auxiliary systems have different forms and specifications. In engineering design, the forms and specifications of various parts are determined based on the types of pulp used in papermaking, paper types, and output requirements.

Different types and specifications of paper machines have regulations on the components to be configured. The domestically produced paper machines are all designed according to the standard series specifications; however, in order to meet the various special needs of users

The lifting mechanism of the rewinder should rise and fall steadily and rise and fall in parallel. The bottom knife roller and the upper knife axis should be parallel to the bottom roller, the distance to the bottom roller should be accurate, and the rotation should be flexible. After the slitter rewinder is installed and calibrated, check whether all the parts are intact, whether the connecting bolts are tightened reliably, and whether the movable parts are flexible, and then fill the lubrication parts with corresponding lubricating oil. Clean, clean, check and refuel. It can be turned on after confirming that it is correct.

The maintenance of the rewinder should pay attention to the following three points. As long as practical attention is paid to production, the service life of the rewinder will be extended. Improve productivity.
