PRINTING UNIT WITH SYNCHRONISED CONTROL FOR ROTARY OR FLAT SILK-SCREEN PRINTING MACHINES
摘要：
A printing unit for rotary, frame or cylinder (20) silk-screen printing machines, which are used for printing of substrates, and in particular textiles. Two spindles (50) for each printing unit drive a ring (30) of the printing cylinder (20), whereas each spindle (50) is controlled by means of a brushless-type electric motor (60), an epicycloidal reduction gear (70) with reduced play, a toothed drive belt (10), and ball bearings which have a small cross section, such that the digital drives of the electric motors (60) control the speed of the motors (60) in a closed loop. The digital drives are in turn controlled by axis control cards which are integrated in a PLC, in order to obtain synchronisation of the motion of the cylinders (20) and of the conveyor belt (40) for the substrate to be printed.
摘要（中）：

用于旋转，框架或圆筒（20）丝网印刷机的印刷单元，其用于印刷基材，特别是纺织品。 用于每个印刷单元的两个主轴（50）驱动印刷滚筒（20）的环（30），而每个主轴（50）通过无刷型电动机（60），外部减少齿轮（70） ），齿形传动带（10）和具有小截面的球轴承，使得电动机（60）的数字驱动器控制电动机（60）在闭环中的速度。 数字驱动器又由集成在PLC中的轴控制卡控制，以便获得要打印的基板的气缸（20）和传送带（40）的运动的同步。
