Tube coating machine

Application of equipment and operating principle
The DYD01 primer coating machine is one piece of equipment on an automatic aluminum tube production line, and is primarily used for roller coating on the outer surface of the aluminum tube.

In order to get a better print pattern on the aluminum tube surface and increase the printing aesthetic, a white coating should be applied to the outer tube surface. The tube fell into the "V" type ship through the conveyer, and was inserted into the printing mandrel during the reciprocating movement of the pushing rod. When the central spindle is transferred to the coating station with aluminum tube, the aluminum tube comes into contact with the adhesive roller, and will rotate in the opposite direction of the adhesive roller. At this time, the coating is evenly coated on the tube body through the use of a glue stick to finish the background printing. The bottom coated rotary disc then rotates to the unloading manipulator with an aluminum mandrel, which removes the aluminum tube from the bottom coated mandrel and sends it up the conveyor chain. The aluminum tube enters the bottom coating oven with the conveyor chain. After drying using the primer coating oven, the aluminum tube enters the printing machine.

Technical parameters

suitable tube diameter	φ11mm-φ38mm
maximum production rate	60 tubes/minute
motor power	0.75KW (The main power comes from the printing press)
dimension	2500*1800*1200mm

Main features The entire machine can be synchronized with a printing machine, or run separately. The machine is controlled using a Siemens PLC and can be adjusted using frequency conversion. The main parts of the machine, such as the spindle plate and cam, are processed using numerical control equipment, which ensures the accuracy and rotation accuracy of the spindle. The manipulators automatically move up and down the tube. Using an automatic detection function, when there is no tube, the machine will automatically stop printing and working.
