Pre-roller-coating aluminum coil four-color printing forming device and roller coating process thereof

Abstract

The invention discloses a pre-roller-coating aluminum coil four-color printing forming device. The pre-roller-coating aluminum coil four-color printing forming device comprises an unwinding mechanism,a cutting mechanism, a butt joint mechanism, a transmission mechanism, a printing mechanism, a drying mechanism, a water cooling mechanism and an air cooling mechanism, wherein the cutting mechanismis located on one side of the unwinding mechanism; the butt joint mechanism is located on one side of the cutting mechanism; the cutting mechanism is located between the unwinding mechanism and the butt joint mechanism; the transmission mechanism is located on one side of the butt joint mechanism; the printing mechanism is located on one side of the transmission mechanism; the drying mechanism islocated on one side of the printing mechanism; the water cooling mechanism is located on one side of the drying mechanism; the air cooling mechanism is located on one side of the water cooling mechanism; the water cooling mechanism is located between the drying mechanism and the air cooling mechanism; and an adjusting and turning mechanism is arranged on the unwinding mechanism. Four sets of printing units are arranged; a hot air control mechanism is arranged in the drying furnace channel and can adjust the hot air direction; and in the drying process, the drying furnace channel can adjust thelength of the furnace channel to enhance the drying effect.

Description

Technical field [0001] The invention belongs to the technical field of aluminum coil coating, and particularly relates to a four-color printing forming device for pre-rolled aluminum coils and a roller coating process thereof. Background technique [0002] Aluminum is a material with excellent ductility. In industrial production, aluminum is often made into thin plate-like structures, such as Las aluminum coils and painted aluminum coils. The coating process of aluminum coil generally includes the following steps: unwinding, printing, baking, cooling, and receiving. Printing and coating need to be realized by a printing unit. When the pattern is complex, multiple printing units are often required, that is, multiple printing units need to be installed. For example, two-color printing requires two printing units; the following problems are often encountered in current operations; [0003] 1) In large enterprises, in order to avoid the interruption of the processing production line d...

Problems solved by technology

[0004] 2) The drying channels in the drying mechanism used in the current production and processing process are mostly fixed and the drying length is not variable; in the production and processing process, there are often complex and intensive processing requirements for printing patterns; therefore, in the drying In the process or in the drying furnace, a longer drying time or drying process is required; the drying furnace with a constant drying length can no longer meet the production needs; in addition, the wind direction in the drying furnace is generally the same as that of the printed aluminum In the vertical state of the roll surface, when the printing pattern is complex and the printing paint is dense, the vertical wind direction of the direct blowing will often blow the printing paint, which will cause uneven thickness of the printing paint, resulting in color difference in the printing effect;
