The nonwoven textile calender finishing machine can be divided into two rolls, three rolls, four rolls and five rolls of calenders according to the number of rolls; according to the arrangement of the rolls, it can be divided into "L" type, "T" type, "F". "Type, "Z" type and "S" type. It mainly consists of roller, frame, roller distance adjustment device, roller temperature adjustment device, transmission device, lubrication system and control system. In addition to the main components and devices of the ordinary calender, a device for ensuring the accuracy of calendering is added.
The length and diameter of the roll of the nonwoven textile calender finishing machine refer to the length and diameter of the working portion of the roll. The length characterizes the maximum extent of the calenderable article. Since the two ends need to leave the position where the baffle is placed, the effective length of the roll is the roll length minus the non-working surface length.
The aspect ratio of the rolls primarily affects the thickness dimensional accuracy of the rolled product. In addition to the properties of the calendered material, the material of the roll and the length of the working part, it depends mainly on the quality requirements of the rolled product. In order to ensure the thickness dimensional accuracy of the calendered product, according to the production practice experience, the roll length to diameter ratio should be limited to a certain range.
