<p>The present invention the servo motor (10) is connected with gear box (9) with flexible coupling (7), when the motor starts , lifting cam (6) rotates eccentrically. Lifting Cam fork (5) with roller (15) is pivoted on lifting cam (6) outer surface so, when the lifting cam (6) is eccentrically moves in rotational direction the lifting cam fork (5) with roller (15) also moves forward & reverse direction to push the lifting connecting pipe (3) through lifting link (4) so; lifting lever (14) lift the printing trolley (1) up & down, which is resting on T-Slot (11). In the present invention single pair or multiple pair of spiral spring(18) with square threaded lead screw(16) and nut (17) to adjust the spiral spring tension is provided at any place of the lifting connecting pipe (3). Spiral spring mounting flat (20) is provided at the other/distal end of connecting pipe (3).</p> |
