Automatic Roll to Roll Two-Color Screen Printing Machine
1. Winding & unwinding: Pneumatic control bar for easily winding & unwinding.
2. Edge alignment: Roll to roll transmission, the edge of material can be aligned automatically.
3. Feeding length setting: Feeding length of each color can be set by the HMI touch screen, the transmission is by servo motor.
4. Printing function: printing stroke is performed by the servo motor, top grade linear bearing for printing head transmission with high accuracy. Functions: Squeegee stops at front/rear, inching movement, speed control and repeat printing for solid result.
5. Off contact function: the lifting height of the off-contact can be adjusted according to the printing speed to avoid shadow occurred by the screen sticking with substrate.
6. Squeegee cylinder: After pressure setting, the squeegee pressure keeps constant to have more perfect printing result.
7. Printing table: High precision printing table is built by the aerospace purpose aluminum alloy plates with honeycomb structure inside. The surface of the table is hard chrome coated. It’s anti-scratch. The vacuum of the table is even and the strength can be adjusted.
8. Screen frame rack: 4 post up/down movement is driven by the German SEW safety brake motor, the movement is smooth without ink stray.
9. Safety structure: When lifting screen frame for cleaning, the 4 safety cylinders at 4 corners will move up synchronously for safety supporting. The emergency stop button also installed at each corner. All the motors, electric components and pneumatic parts all conform to the CE standard.
10. Dryer: High efficiency force air designed to have quick drying speed and the material will not deform easily. Equip filter, exhaust motor, lifting cylinder of upper cover.
(Drying system: Flat oven, vertical oven, UV lamp oven and UV + Hot air oven are available for option. )
