[0002] The calender is a machine that presses and stretches rubber or plastic into a film of a certain thickness and surface shape, and can hang glue on the fiber cord canvas or steel cord. The calender can be divided into two rollers and three rollers according to the number of rollers. , four-roll and five-roll calenders, etc. At present, the existing calenders are mainly composed of pressure rollers, racks, roller distance adjustment devices, roller temperature adjustment devices, transmission devices, lubrication systems and control systems, etc. The existing calenders The roller distance adjustment device adopts electric and manual methods to adjust the roller distance. The above two methods belong to mechanical distance adjustment. The problem of mechanical distance adjustment is that the adjustment accuracy is low and it cannot meet the use requirements well.
