The calender is composed of two or more rollers, arranged according to the heating method, which can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite film, graphite sheet, suction Wave materials, shielding materials, magnetic materials, non-ferrous metal materials, etc. Hot pressing is divided into water heating, electric heating, oil heating and electromagnetic heating. It is a machine that presses and stretches materials such as rubber, silica gel, silicone rubber, phase change material, PTFE or plastic into a film with a certain thickness and surface shape at a certain temperature, and can glue fiber curtain canvas or steel cord fabric. . Calenders can be divided into two-roller, three-roller, four-roller and five-roller calenders according to the number of rollers; according to the arrangement of rollers, they can be divided into "L" type, "T" type, "F" type, " Z" type and "S" type, etc.
The ordinary calender is mainly composed of rollers, frame, roller distance adjustment device, roller temperature adjustment device, transmission device, lubrication system, control system and roll removal device. In addition to the main components and devices of the ordinary calender, the precision calender has added devices to ensure the calendering accuracy, such as pressure maintaining system, bearing clearance adjustment system, etc.
