The Base Coating Machine is a highly automated equipment that specializes in printing lead tin, aluminum and other metal tube primers.The formed aluminum tube comes from the annealing oven or lacquer curing oven, and has the functions of automatic feeding, automatic intubation, automatic detection and automatic extubation. After the aluminum tube is printed, it is automatically inserted into the drying oven conveyor chain and sent to the drying oven for drying. If the aluminum tube is empty, when the mandrel of the missing aluminum tube turns to the printing position, the printing ink roller can automatically retreat. Realized by mechanical joint control.

This machine uses the same main power as the pattern printing machine in the production of the whole line, so it can be kept in complete synchronization with the printing machine. The spindle rotation motor adopts frequency conversion speed regulation. The whole machine is controlled by PLC, and it will automatically give way without any tube to avoid printing on the mandrel. The printing rubber roller of polyurethane material is convenient to use, saves the cost, improves the printing quality, and is durable. The machine's eight-axis disc, cam and other main parts are processed by numerical control equipment, which ensures the accuracy of mandrel operation and rotation accuracy, and improves the printing effect.
