A. Paper Feeding Section
1) Core Configuration: Adopts a pre-feeding system, paired with an air-assisted paper feeding device with a 7.5KW fan. It can adapt to cardboard of different curvatures by adjusting air flow; the paper feeding wheels are made of ultra-wear-resistant material from Taiwan, supporting switching between single-sheet/continuous feeding modes. It is centrally controlled by a 7-inch computer touch screen, which can display production volume, trigger count alarms, and adjust phases.
2)Adjustment & Protection: Side baffles and rear baffles are electrically adjusted, while the front baffle is manually adjusted; it is equipped with a pneumatic alignment device (alignment timing controlled by computer) and a paper dust removal device to remove impurities on the printing surface of cardboard; the main motor and fan are both variable-frequency motors, saving 30% energy with stable startup. Meanwhile, it has a clutch alarm bell, air pressure interlock device, and motor protection device to ensure operational safety.
3)Comparative Advantages: Compared with traditional mechanical pre-feeding, the servo pre-feeding system of similar equipment (e.g., SYK-1200 series) drives the paper feeding wheels through an independent servo motor, enabling zero-pressure transmission of cardboard to avoid corrugated damage. It can save 20g/m² paper for three-layer cardboard and 40g/m² paper for five-layer cardboard.
B. Printing Section
1) Core Components: Supports 1-4 optional colors for printing. The outer diameter of the printing roller is 395mm (410mm including the plate), processed by steel pipe surface grinding + hard chrome plating, and adjusted by dynamic balancing; the anilox roller has an outer diameter of 180mm, with optional mesh sizes of 180-260, also treated with surface grinding, embossing, hard chrome plating, and dynamic balancing. It is paired with a wear-resistant rubber roller with an outer diameter of 180mm and a hardness of 60-65 degrees to ensure uniform ink distribution and transfer.
2) Adjustment & Control: Uses a planetary gear structure for phase adjustment; the printing phase can be adjusted 360 degrees via the computer screen (both in running/stopped state), and the horizontal position is manually adjusted with a tolerance of ±10mm; a pneumatic diaphragm pump is equipped to achieve stable ink supply, with an ink filter to remove impurities. The printing phase is fixed by a cylinder-type braking device, and the motor can be controlled to forward/reverse via a foot switch during plate changing.
C. Die-cutting Section
1) Core Components: Adopts a rotary die-cutting structure, with the die-cutting roller (outer diameter 395mm) processed by steel pipe surface grinding + hard chrome plating and dynamic balancing. The die-cutting blade plate is made of high-precision 45# steel, and the pressure roller (outer diameter 395mm) uses a high-wear-resistant rubber layer (Shore hardness 85-90 degrees) to ensure stable die-cutting force.
2) Adjustment & Control: The die-cutting pressure is adjusted by a worm gear mechanism (with a digital display of pressure value), and the phase of the die-cutting roller can be adjusted 360 degrees via the computer screen (synchronized with the printing phase). It is equipped with a die-cutting waste discharge device (powered by a 1.5KW motor) to collect and discharge waste paper edges automatically.
3)Comparative Advantages: Compared with flat die-cutting, this rotary die-cutting system has 2-3 times higher efficiency, and the die-cutting accuracy error is controlled within ±0.1mm (suitable for fine patterns). For equipment like the SYK-1200, the quick-change die-cutting plate structure can reduce plate-changing time by 50% compared to traditional models.
