Press roller position automatic correction mechanism and automatic correction method of screen press

The present invention provides a press roller position automatic correction mechanism and an automatic correction method of a screen press which are able to maintain the position of the front end of a press roller in the horizontal direction to be a level so as to obtain enough printing precision. The screen press with a screen (11) and the press roller (20) comprises: an angle regulator of an adjustable press roller (20); a laser displacement meter (15) capable of measuring the horizontal distance of the front end of the press roller (20) in the vertical state, namely a first distance, and an included angle between the screen (11) and the press roller (20), namely the horizontal distance of the front end of the press roller (20) in the angle inclination state, and namely a second distance; and a press roller driving tool (12) horizontally moved from the position where the angle inclination begins to the position where printing starts according to the distance difference between the first distance and the second distance.
