Product Description

Application and operating principle

XR09 6-color printing machine is suitable for printing the surface of metal tubes like aluminum tubes and cans. It can realize polychrome printing of patterns in six colors.

Base coated and dried germ tubes move into the tube slot and are inserted over printing mandrel by push rod. The ink is transferred to printing plate through ink fountain, ink roller, middle roller, oscillating roller and rubber roller. The printing plate then transmits the pattern to the blanket cylinder with appropriate pressure and prints tubes with desired patterns. The manipulator takes tubes away from the mandrel and sends them to the transfer chain towards the drying oven. Aluminum tube printing adopts circle presses circle to realize polychrome printing.

Main features

If tubes are not well inserted into mandrels, the machine will stop working. No tubes, no printing. Printing mandrel rotates automatically and can change frequency and speed. The printing units adopt Branch and R plate structure which is easy for replacement.
• Point-moving regulating handle makes it easy to regulate printing.
• Draw-out type printing components are convenient for replacement.
• Mandrel components adopt integral replacement, which is suitable for different types of aluminum tubes and convenient for changing mandrel.
