Base coating machine

Description
The DYC01 primer coating machine is suitable for the printing of aluminum, lead, tin and some other metal cans' circumferential surface in the form of background color rolled printing.

To make the surface of the aluminum can easier for printing patterns and add aesthetic sense to the printing, a layer of bottom ink is printed over the outer surface of the aluminum cans before printing patterns. The cylindrical shape is caught by the vacuum suction drum after passing the conveyor chain. The putt plugs the printing mandrel in the cylindrical shape. When the mandrel reaches the coating station with the aluminum cans, the aluminum cans touch the glue roll which is stick with the iron printing coating. The aluminum can moves against the glue roll and in the meantime, the iron printing coating is printed over the can body evenly by the PU glue roll to finish the grounding printing. Then the primer turntable with the mandrel which is bringing the aluminum cans with itself rotates to the unloading robot. The unloading robot takes off the aluminum can from the primer mandrel and send it to the transferring chain. The aluminum cans go into the primer drying oven along with the chain. After being dried by the primer drying oven, the aluminum cans are sent to the coating machine.

Features The whole primer coating machine is controlled by the Siemens PLC and operated by the Pro-face color touch screen. It can realize that all the operations is controlled smartly. The movement shaft, cam and some other main parts of the machine are processed by CNC equipment to guarantee the operational accuracy of the mandrel and the rotation accuracy. The mechanical arm which is also called the robot sends and outputs the cans automatically. It has the function of automatic detection which can make sure that the equipment can be out of service automatically when can taking is poor and stop printing without cans. The replacing auxiliary system of the mandrel can realize the fast interchange of the mandrels. The coating machine has good configuration. Most shafts of this machine adopt FESTO pneumatic components and the bearings of this machine adopt NTN, NSK and so on. Chain Indexer Robot
