The equipment is mainly used for the printing of sheet metal or coating after the drying, the main line from the conveyor, feeding device, drying, cooling, unloading, accumulation. The main heating energy is applicable: electricity, city gas, liquefied petroleum gas, natural gas, diesel, kerosene, coal-fired stoves and other energy sources can also be used.Using imported PLC and frequency controller, to achieve shaftless transmission, to ensure that the feed, printing, unloading, receiving, conveying synchronization.Before and after the drive is closed, handsome in appearance.Unloading protection, tension conveyor chain, metal sheet metal Qi Qi are using pneumatic control to achieve.Adopting the stepless speed change in the iron feeding part, it also adopts the vacuum absorption and servo system to implement the buffer to ensure the metal sheet does not bruise or bruise at high speed.
