Abstract
The utility model relates to a winding and unreeling device for a vertical continuous annealing furnace. The device is suitable for the continuous annealing of a metal thin strip with min-sectional area size and the requirement for extremely high accuracy of the micro tension and constant tension at high temperature. According to the winding and unreeling device provided by the utility model, by actively unreeling by virtue of a unreeling machine 1 at the top of the furnace, the required tension generated by the weight of a mobile device 6 at the bottom of the furnace, the tension of the strip in the annealing furnace can be adjusted by adjusting the weight of the mobile device 6, when the weight of the mobile device 6 is constant, the tension of the strip in the annealing furnace is constant, a closed-loop control is formed between a position sensor 7 on the bottom of the furnace and a winding machine 9, and when the mobile device 6 deviates from the position sensor 7, the coiling speed of the winding machine 9 is correspondingly adjusted so as to ensure that the strip speed on the winding machine and the strip speed on the unreeling machine are synchronous.
