Abstract

A stamping machine includes a casing on which a press-printing assembly is mounted which included a heated pressing cylinder and a gripper member with a gap defined therebetween. A first conversion member with a first pattern releasably formed thereon is displaced to extend through the gap. A second conversion member with a second pattern releasably formed thereon is displaced to extend through the gap. A guiding member is provided for introducing the workpiece into the gap to be urged and pressed between the first and second conversion members such that the first and second patterns on the first and second conversion members are respectively printed on the top and bottom faces of the workpiece.

A stamping machine for printing patterns onto a workpiece (80) which includes a top face and a bottom face, said stamping machine comprising:

a casing (10) having a first side (102), a second side (104) and a top portion (106) with a first end adjacent to the first side (102) and a second end adjacent to the second side (104);
a first base (12) formed on the first end of the top portion (106) of said casing (10) and including a first roller group (30) mounted thereon;
a second base (14) formed on the second end of the top portion (106) of said casing (10) and including a first driving roller (39) mounted thereon;
a third base (13) formed on the first side (102) of said casing (10) beneath said first base (12) and including a second roller group (40) mounted thereon;
a fourth base (15) formed on the second side (104) of said casing (10) beneath said second base (14) and including a second driving roller (45) mounted thereon;
a press-printing assembly (60) mounted on a mediate portion of the top portion (106) of said casing (10) and including a heated pressing cylinder (61) and a gripper member (63) with a gap (602) defined therebetween;
a first conversion member (90) with a first pattern releasably formed thereon having a first end stretched on said first roller group (30), a second end mounted around said first driving roller (39) and a mediate portion extending through said gap (602) between said heated pressing cylinder (61) and said gripper member (63);
a second conversion member (91) with a second pattern releasably formed thereon having a first end stretched on said second roller group (40), a second end mounted around said second driving roller (45) and a mediate portion extending through said gap (602) between said heated pressing cylinder (61) and said gripper member (63);
and
a guiding member (50) mounted on said first base (12) for introducing said workpiece (80) into said gap (602) to be urged and pressed between said first and second conversion members (90) and (91) such that said first and second patterns on said first and second conversion members (90) and (91) are respectively printed on the top and bottom faces of said workpiece (80).
