YFD semi-automatic printer Semi-automatic chain feeder and side rail for orientation ensure feeding precisely. Design by CAD, can combine multi-color printer at will. Each link position can be locked pneumatically and opened electrically. After machine section is moved out, the pneumatic device will be affected to make machine section's gear meshed accurately, printing phase fixed to secure the gears engaged precisely in case the unit is locked. To protect the forme, the anilox roller separate with the surface of the forme automatically when the machine stops. With the pneumatic diaphragm pump, it is stable in ink supply. The automatic-running system of the anilox roller can avoid the ink drying fast when the machine is paused. Clean ink automatically. All cylinder are plated hard chromium and never be rusted. On the surface of the anilox roller, the transmit lnes are carved to stick rapidly the forme. The anilox roller can choose 165 lines, 180 lines, 200 lines, 220lines at will. Transmitting gears transmit without side clearance after be heat treated and be grinded precisely Gears with lubricating oil have long using life, low noise and stable performance. Electrical planetary gear system is designed for adjusting phase position. Adjustment dial display. Automatic counter can record the output accurately. Regulate slitting and creasing manually. The slitter is designed specially with long using life and is anti-abrasion.
