Description:

1. Main driving structure: Controlled by INOVANCE frequency controlled motor, axle coupling driving.

Feature: Stable running.

2. Shaftless printing roller fixing System: adopt pneumatic cylinder fixing style to drive the printing roller core, and transverse adjustment through screw.

Feature: Swift printing roller replacement, so as to insure the concentric of printing rollers to improve printing precision. 

3. Ink scraper structure: use air diaphragm pump to cycling and feeding ink; doctor blade slowing drive by low speed synchro-motor which can be up & down and angle adjusted; the pressure controlled by double pneumatic cylinder.

Feature: increase service life of printing roller and easy use.

4. Imprinting ascending and descending structure: controlled by twin pneumatic cylinder synchronous ascend and descend; oscillating arm type cylinder seat to insure the stability of material tension.

Feature: insure the pressure equalization, decrease chromatic aberration.

5. Overprint Mechanical hand: longitudinal automatic overprinting adjusted by micro-computer (through photocell detecting) and synchronous motor (through screw rod slow driving).

Feature: flexible, stable, and high overprint precision.

6. Rewinding and unwinding system: double stations, auto-cutting and connecting for rewinding, and controlled by moment motor; Rewinding traction adopt vector frequency controlled motor. Unwinding adopt magnetic powder brake constant tension controlling. Feature: low tension variety, to reduce waste and cost-cutting.  

7. Drying & cooling system: drying tunnel wind cycling by centrifugal blower; temperature controlled by intelligent temperature controller; material cooling by singe unit wind cooling device.
