Thermal cycle type annealing calender and method thereof

The invention provides a thermal cycle type annealing calender and a method thereof, and relates to the technical field of annealing calenders. On one hand, when the tensioning force needs to be adjusted, the tensioning force can be adjusted through two methods, when large-amplitude adjustment needs to be conducted, a first electric cylinder is directly controlled to stretch out and draw back, and large-amplitude adjustment of the two second conveying rollers can be achieved when the first electric cylinder stretches out and draws back; and on the other hand, when small-amplitude adjustment needs to be carried out, a first motor is controlled to rotate, when the first motor rotates, a threaded rod can be driven to rotate, height adjustment of a connecting block and a mounting arm can be achieved under driving of the threaded rod, and compared with an existing device, the device can achieve tensioning at different tensioning speeds, is higher in practicability, and is suitable for popularization and applicatio
