The working principle and operation precautions of the calender
Release time:
Dec 07,2023
The calender usually works in the form of continuous extrusion. The printed matter is fed from the paper feed table to the calender rod between the pressure roller and the pressure roller. Under the action of temperature and pressure, the coating is stuck on the surface of the calender and smeared. After the coating layer will slowly cool down, after which will form a bright surface. The calender strip is a uniquely processed stainless steel ring-shaped steel chain. There are many far infrared heating sources inside the pressure roller to provide the heat required in the smearing process. The working pressure of the roller is generally an electric variable oil pressure system, which can accurately meet the size requirements of the polishing pressure, and the polishing speed can be controlled by a variable speed drive motor or a slip motor. The calender contains a plurality of rotating rolls and the apparatus is one hundred percent automated and controlled by the main control room. In the maintenance or overhaul of the calender, attention should be paid to the following aspects: 1. When carrying out maintenance or repair work, it is very important to disconnect the power supply in the relevant area from the protection switch of the independent motor to avoid accidental activation of the calender. 2, the rotating roller can not force or contact with other objects. The noise of the calender will not be less than 85 decibels, so the personnel nearby must remember to wear hearing protection equipment. When the calender is running, all mechanical equipment adjustments with risk factors are expressly prohibited. 5. When the paper is broken, the pressing area will automatically open. When the calender is working, no one is allowed to enter the extrusion zone. The working principle and operation precautions of the calender are introduced here. I don't know if you have a further understanding of this problem after reading the above introduction.
