Background

Aluminum is a material with excellent ductility, and is often manufactured into a plate-shaped structure with a very thin thickness in industrial production, such as a roll of las aluminum and a roll of painted aluminum. The coating process for aluminum coils generally comprises the following steps: unreeling, printing, baking, cooling and receiving material. Printing and coating are realized by using a printing unit, when the patterns are complex, multiple times of printing are often needed, namely, multiple sets of printing units are needed to be installed, and if double-color printing needs two sets of printing units; the following problems are often encountered in the current operation;

1) in large enterprises, in order to avoid the interruption of production caused by the replacement of an aluminum roller, and to keep continuous production and working efficiency, an aluminum roll butt-joint mechanism is added between the unreeling and the printing, and the tail end of the previous aluminum roll and the starting end of the standby aluminum roll can be quickly connected and fixed by aluminum roll butt-joint; forming a butt joint port with two mutually crossed sides at the butt joint position of the aluminum coil through a butt joint mechanism, inserting a resistance strip into the butt joint port, and flattening and driving the butt joint port through a transmission mechanism; in the traditional production mode, the resistance strips need to be manually inserted by staff, and the manual dependence is serious;

2) a drying furnace channel in a drying mechanism used in the current production and processing process is mostly fixed and the drying length is not variable; the processing requirements of more complex and dense printed patterns often appear in the production and processing processes; therefore, a longer drying time or drying process is required in the drying process or in the drying tunnel; the drying oven channel with invariable drying length can not meet the production requirement; in addition, the wind direction in the drying furnace channel is generally vertical to the surface of the printed aluminum roll, when the printed patterns are complex and the printing paint is dense, the printing paint is blown by the vertical wind direction of direct blowing, so that the phenomenon of uneven thickness of the printing paint occurs, and the printing effect is poor;

therefore, an automatic printing forming device is needed, and meanwhile, the drying device can be adjusted according to different printed patterns, so that the printing effect is ensured.
