Product Description
1. Paper feeding section:
Our state-of-the-art servo pressure-free extended paper feeding front edge adopts an innovative design that eliminates the need for traditional paper guide rubber rollers and embossing roller pressure feeding mechanisms. The cardboard transitions seamlessly to the printing roller via the front edge vacuum. The key power input gear of the paper feeding section's intermittent divider is synchronized with the vacuum paper guide wheel's outer circle at the front edge pressure-free section. This advanced design simplifies operations, extending auxiliary paper feeding time to its maximum and allowing for effortless paper feeding time adjustments.
The paper feeding section utilizes the renowned French Martin front edge paper feeding structure, featuring a unique table top that tilts and lifts to streamline the feeding process. With a lower front and higher back table top during lifting and feeding, it significantly mitigates paper jams and cardboard damage, making it ideal for single corrugated and curved cardboard. The Martin bellows, a snail-type suction blower, delivers concentrated power to maintain alignment, even with high-strength or heavier cardboards. The light-pressure bearing wheel frame design facilitates table lifting and lowering, reducing weight load and enhancing speed in the pressure-free section.
Our pressure-free front edge paper feeding system is a game-changer, resolving the issue of cardboard damage from paper guide rubber rollers. It guarantees nearly 100% preservation of the cardboard's physical attributes, providing carton manufacturers with a wider selection of paper. By removing the paper guide rubber roller conveying mechanism, all cardboards remain unharmed during transport, achieving what other systems cannot.
