Function Of Printing Department： 1.The printing roller and trace pressing roller adopt good quality steel material.To grind the surface and do the hard chrome plating. 2.To correct by dynamic balance,so the revolving is steady. 3.To load and unload the printing plating and step on the switch.Electric controlling the positive and negative revolving. 4.The space of the printing & pressing roller is adjusted by hand.The scale panel shows the data. 5.Phase-adjusting mechanism,planet type gear structure. 6.Priting phase fixed device,pneumatic brakes.While the machine separates or the phase is adjusting,the brakes can restrict the revolviing of the machine platform and keep the fixed point of the original gears'position. 7.Rubber roller:The surface of the roller is steel pipe which is packed by the wear-resisting rubber.Adoping medium and high special grinding the rubber roller has effective ink-spreading. 8.The oil roller adopt high precision hard chrome plating net-grain roller. 9.Installed with ink roller rotation electrical machinery to the main engine's drying up while its stopping.
