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.
A. Tube diameter range: φ16mm-φ25mm or φ25-φ35mm
B. Tube length range: ≤200mm
C. Production speed: ≤120tubes/min
D. Motor power: 11KW
E. Dimensions: 3340*2330*2100mm
F. Net weight: 7600KG
G. Intake pressure: 0.5Mpa
A. It adopts SIEMENS PLC and Pro-face color touch screen to display information of speed and production. The machine has self-inspection system. 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.
B. Point-moving regulating handle makes it easy to regulate printing.
C. Draw-out type printing components are convenient for replacement.
D. Mandrel components adopt integral replacement, which is suitable for different types of aluminum tubes and convenient for changing mandrel.
