PET Film Printing Machine

Model: DNAY800B, DNAY1100B

Design Advantages of the PET Film Printing Machine
1. Main transmission mechanism
This PET film printing machine is equipped with a frequency inverter from Shenzhen Inovance Company to control the electric motor, and finally achieves the goal of driving each group of printing cylinder. The transmission mechanism makes the printing equipment highly energy efficient.

2. Shaftless printing cylinder mounting mechanism
Our PET film printing machine makes use of an air cylinder for printing cylinder mounting, and the transverse movement of the printing cylinder is achieved via a screw rod. This ensures fast printing cylinder mounting and high concentricity between the printing cylinders, thus ensuring high printing quality for final products.

3. Doctor blade
The doctor blade of the printing machine is movable up and down and its contact angle is adjustable as well. The pressure force on the doctor blade is controlled by dual air cylinders, and an electric motor is utilized to drive the cam to rotate to achieve the transverse movement of the blade. This doctor blade design effectively extends the lifespan of the printing cylinder.

4. Impression cylinder lifting mechanism
The impression cylinder of the PET film printing machine adopts dual air cylinders for pressure control and an electromagnetic valve for self-locking and positioning. This design provides protection against air cylinder leakage and failing of the air cylinder due to printer shutdown. This also ensures uniform printing pressure and consistent printing color.

5. Color registration system
The PET film printing machine has a computer controlled synchronized motor to drive the double ball screws via a speed reducer, thus achieving pre-printing color registration and automatic color registration during printing process.

6. Roll material rewinding and unwinding system
Our PET film printing machine is manufactured with dual-station rewinding and unwinding unit to achieve automatic roll material replacement and automatic material rewinding. In order to achieve constant unwinding and rewinding tension force and traction force, the film printing equipment utilizes a vector controlled frequency inverter for linear speed adjustment. As compared with common printing machines with three vector controlled motors, our seven-motor PET film printing machine can save 15m film material and 20% printing ink, solvent and energy at material rewinding speed of 120m/min.

7. Energy efficient drying and cooling system
The drying system of our PET film gravure printing machine includes a fully enclosed oven, an external secondary heat source return air system, and an intelligent temperature controller. The printer cooling system has water cooled returning rollers to reduce the temperature on PET film material. In addition, we can equip our printing machine with a drying system with external steam and conduction oil combinational heating system, with an additional cost.

Applications
The PET film printing machine is multifunctional. It can be used for printing on not only PET film, but also BOPP film, CPP film, PC film, PVC film, and various composite film with similar properties. It can also be used for paper printing. The printing equipment offers a maximum printing speed of 120m per minute and the mechanical speed is 130m per minute.
