Tension control system of photogravure press

The utility model discloses a tension control system of a photogravure press. The tension control system comprises at least two swing rollers and at least three guide rollers, wherein the two swing rollers are simultaneously driven by the same swing arm, and the guide rollers are sequentially arrayed. A thin film material sequentially passes through the guide rollers and the swing rollers as required. After the structure of each swing roller is transformed, double-tension control can be achieved by flexibly changing the material film moving mode according to the tension requirements of the thin film material in the actual printing production According to the transforming scheme, influences on other parts of gravure equipment is little, and accuracy of the gravure equipment can not be influenced.
