Screen printing machine for printing e.g. compact disk, has screen support supported by columns displaced vertically for adjusting distance between screen and object, and cylinder simultaneously raising and lowering columns

摘要

#CMT# #/CMT# The machine (8) has a printing station (54) with a screen support (68) supported by three columns (78) integrated with a frame (48), where the station has a receiving zone (69) to receive a texture screen (70). The columns, slidingly mounted on a cylinder (80), are non-aligned and positioned on either sides of the zone, where the cylinder simultaneously raises and lowers the columns. The columns are displaced vertically to adjust the distance between the screen and an object (6) to be printed based on the height of the object determined by a sensor (64). #CMT# : #/CMT# An independent claim is also included for a printing device having a screen printing machine. #CMT#USE : #/CMT# Used in a printing device (claimed) for printing an object e.g. compact disk, telephone card and solar cell. #CMT#ADVANTAGE : #/CMT# The cylinder simultaneously raises and lowers the columns to adjust the distance between the texture screen and the object to be printed in a precise manner, thus improving the printing quality and avoiding breakage of fragile objects. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a printing device. 6 : Object 8 : Screen printing machine 48 : Frame 54 : Printing station 64 : Sensor 68 : Screen support 69 : Receiving zone 70 : Texture screen 78 : Columns 80 : Cylinder.
