◆ Consistent dot patterns and even inking.

◆ Extended service life of the printing plate and rubber roller. ◆ The anilox roller gap adjustment features a self-locking mechanism with an adjustment range of 0-8mm.

4. Rubber Roller:

◆ The ink distribution roller is coated with wear-resistant rubber. The center height of the roller is parabolic to compensate for deformation under load and improve ink transfer. The rubber is made of nitrile butadiene rubber with a Shore hardness of over 60 and a special polishing process for excellent ink transfer. The roller is driven by a motor when the main machine is shut down, automatically distributing the ink without stopping the machine.

◆ The rubber roller gap adjustment features a self-locking mechanism with an adjustment range of 0-8mm.

5. Phase Adjustment Mechanism:

◆ Planetary gear mechanism.

◆ The printing phase is computerized and digitally controlled, allowing 360-degree adjustment (adjustable both during operation and at rest).

◆ The lateral displacement of the printing roller is electrically adjusted with an adjustment range of ±5mm.

◆ The printing plate roller uses electrically adjusted phase, enabling fast zeroing and plate adjustment, and high plate adjustment accuracy. 6. Paper Feed Shaft

◆ Upper paper feed roller,

◆ Lower paper feed roller, and lower paper guide roller are hard chrome-plated.

◆ The paper guide roller gap adjustment uses a self-locking mechanism with an adjustment range of 0-11mm.

7. Ink Circulation Structure:
