Abstract
“ROTATIVE PRINTING MACHINE WITH AUTO-TENSIONABLE RULER”, it deals with an auto-tensionable ruler (1) by spring (2) contiguous to the movable bushing (3), both annexed to the main axle (4) that receives by extreme connection (5) the printing paste spilled by holes (6), in order to make possible the scattering of said paste in the interior of the cylinder (7), in this manner making possible the preparation and/or assembly of surplus sets of stamping (CE) outside the machine (M), being the relative position of the said sets demarcated in points of reference (15) in the bushing (8) and in the flange (16) receiver of the cylinder (7).
Claims1
“ROTATIVE PRINTING MACHINE WITH AUTO-TENSIONABLE RULER”, a ruler (1) formed from a passer-by axle (4) with holes (6) for passage of the paste, in whose an extremity it has a rotative bushing (10) fixed to the axle (4) and, in the opposite extremity a removable rotative bushing (3) fixed by cotter (C);
- the axle (4) presents a spring (2) that keeps the stretching of the cylinder (7) located between the disc (d) fixed in the axle (4) and the removable bushing (3);
- from the bushings (3 and 10) derive the belts (8 and 9);
- the fixed bushing (10) is fastened to the axle by weld (S) or another way of setting already known;
- the central projections (18) of the belts (8 and 9) have lock-pin (19) used to guarantee that the print of that cylinder (7) is, when of the locking, in the correct position of stamping;
- the set of stamping (CE) is supported in supports (24) connected to the axle (25) of the pistons (26) that adjust the height of the ruler (1) in relation to the carpet (11), increasing or reducing the contact;
- the carpet (11) keeps a uniformity of displacement thanks to lateral guides (27), being overlapped the table (13), located above of magnets (12) or electromagnets (12I), whose magnetic field is adjusted by the tension applied to the same;
- the belts (8 and 9) turn thanks to the parallel bearings (28) limited in the due positions for lock ring (29), having still retainers (R);
- the removable bushing (3) is fastened to the axle by cotters;
- markings of reference (15) detach as much in the belts (8 and 9) how much in the flanges (16);
- the flange (16) has two marks (15 and 15′), being the mark of reference (15) which must be lined up to the mark (15) of the bushing in the assembly of the machine and the marks (15′) of glue of the cylinder in the flange, foreseeing the alteration of the measures to promote the rabbet of the drawing;
- when assembling the cylinder (7), it must be kept the references (15) lined up and the pin (19) locked;
- below of the related table (13), the magnets (12) are located and act as much in the faces (17) of the belts (8 and 9) how much throughout the baton (14) of scattering of the paste;
- the movement of magnets (12) occurs by a screwed spindle (30) supported in bearings (31), this spindle (30) is connected to the motor-reducer set (32).
