Servo motor drives the suction belts to send bottom paper which includes cardboard, grey board and 3-ply, 4-ply, 5-ply and 7-ply corrugated board with A/B/C/D/E/F/N-flute. The sending is smooth and precise.
With strong suction design, machine can send paper with thickness between 250-1100g/㎡.
HBZ-170 bottom sheet feeding part uses dual-vortex pump with dual-solenoid valve control, aiming at 1100+mm width paper, can start a second air pump to increase air suction volume, function better on conveying warping and thick corrugation board.
