A polyester or epoxy base is applied over the tubes to receive prints. Germ tubes dropping into “V” slot are inserted over mandrel by push rod mechanism. The mandrel turns to the coating station, coating is applied with rotating rubber rollers over the spinning tubes.
Coated tubes are unloaded by manipulator. The manipulator takes tubes from the mandrel and puts them on the transferring chain towards the base-coating oven.
A. Tube range: φ11-φ38mm
B. Production speed: ≤60tubes/min
C. Motor power: 0.75KW (main power from printing machine)
D. Dimensions: 2500*1800*1200mm
E. Weight: 1800KG
A. The machine can work synchronously with printing machines or work alone.
B. SIEMENS PLC controls speed and frequency. Mandrel rotation adopts frequency control.
C. Main units of the machine like mandrel plate and cam are processed by CNC equipment, which increase the accuracy of mandrel rotation.
D. The manipulator takes tubes up and down automatically. The machine has self-inspection system. If tubes are not well inserted into the mandrels, the machine would stop working automatically. No tubes, no printing. The mandrel can be prevented from being accidentally coated.
