Background
In the printing process of the general double-color printing machine series products, the paper can be printed in three conditions of front double-color printing or back double-color printing or one front double-color printing and one back double-color printing according to the requirements of customers. The conventional two-color printer can only print the back side of the paper without turning over, and if the printing of the second group of paper is required, a group of turning frames must be added to reverse the back side of the paper, so as to print the second color on the front side of the paper, as shown in fig. 1 and 12. However, this has the following drawbacks: 1. the front and back tension can not be ensured to be consistent during printing, so that the winding tightness can not be ensured during winding, and the quality of the product is not in accordance with the requirements of customers; 2. when the second group of color register is printed, because the air blowing device is arranged on the upper side of the roll-over stand, the color register at the back side is inaccurate (the color register of the second group of print color is run) due to uneven air quantity; 3. when printing 650 broad widths, the roll-over stand needs to be arranged above the printing group, and the height reaches about 3 meters, so that great inconvenience is generated for paper passing and adjustment.
