<p>The present invention is used for lifting the angle of flat bed screen printing machine. The servo motor (10) is connected with gear box (9) with coupling (7), when the motor starts , the shaft of the motor also rotates which transmit their rotational motion to the gear box (9). Cam (6) is connected with gear box (9) so, when the motor runs, cam (6) rotates eccentrically. Lifting Cam fork (5) with roller (15) is pivoted (Line Contact) on cam (6) outer surface so, when the cam (6) is eccentrically moves in rotational direction the lifting cam fork (5) with roller (15) also moves forward and reverse direction to push the lifting connecting pipe (4) through lifting link (3) so; lifting lever (14) lift the printing trolley (1) up & down, which is resting on T Slot (11). T Slot (11) is fitted on lifting angle (12).</p> |
