Description

Four-color printing forming device for pre-roll coating aluminum coil and roll coating process thereof

Technical Field

The invention belongs to the technical field of aluminum coil coating, and particularly relates to a pre-roll coating aluminum coil four-color printing forming device and a roll coating process thereof.

Background

Aluminum is an extremely ductile material that is often used in industrial applications to make very thin plate-like structures such as rolls of aluminum for placians and colored drawings. The coating process of aluminum coils generally comprises the steps of: unreeling, printing, baking, cooling and collecting materials. The printing and coating are realized by using a printing machine set, and when the pattern is complex, multiple printing is often needed, namely, a plurality of printing machine sets are needed to be installed, for example, double-color printing needs a double-printing machine set; the following problems are often encountered in the current operation;

1) In large enterprises, in order to avoid the interruption of production of a processing production line due to the replacement of a material aluminum roller, an aluminum coil butt joint mechanism is added between unreeling and printing in order to maintain continuous production and working efficiency, and the tail end of the last aluminum coil and the initial end of the standby aluminum coil can be quickly connected and fixed through aluminum coil butt joint; the butt joint of the aluminum coil is formed into a butt joint opening with two mutually crossed sides through a butt joint mechanism, then a blocking strip is inserted into the butt joint opening, and the butt joint opening is flattened and transmitted through a transmission mechanism; in the traditional production mode, the blocking strips are needed to be manually inserted by staff, and the manual dependence is serious;

2) Most of drying furnace paths in a drying mechanism used in the current production and processing process are fixed, and the drying length is not variable; the complex and dense processing requirements of printed patterns often occur in the production and processing processes; thus requiring a longer drying time or drying process in the drying process or in the drying oven; the drying furnace path with invariable drying length can not meet the production requirement; in addition, the wind direction in the drying oven is generally vertical to the surface of the printed aluminum coil, when the printed patterns are complex and the printed paint is dense, the directly blown vertical wind direction often blows the printed paint, and the phenomenon that the printed paint is uneven in thickness and thickness can occur, so that the printing effect has chromatic aberration;

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