A. Paper Feeding & Conveying   1.Face Paper System: Taiwan-imported suction feeder (powerful suction for smooth feeding) + PU wear-resistant rubber sun wheel (new soft material) with belt feeding (prevents print surface wear, adapts to various paper thicknesses).   2.Bottom Paper System: Imported perforated belt suction feeder + synchronous claw mechanism (compatible with 300g/m²+ cardstock, A-F/N corrugated boards, 3/5/7-layer paperboard) for high-speed stable feeding. B.Transmission & Control   1.Drive System: Imported synchronous belts + Japanese chain-driven push claws (alignment error ≤±1.5mm, low paper damage rate).   2.Control System: Original Japanese precision phase adjuster (corrects fitting errors at high speed, boosts efficiency); world-renowned electrical components (variable frequency speed control, low ...
