THERMAL PRINTING MECHANISM WITH COMPACTING SYSTEM OF CLAMPING ROLLER Russian patent published in 2019 - IPC B41J2/32 

FIELD: thermal printing.

SUBSTANCE: thermal printing mechanism according to the invention comprises: a thermo-printing mechanism housing, a thermal head, a motor for rotating a clamping roller with a spur gear, pressure roller with clamping bead gear wheel arranged thereon, wherein said pinch roll gear wheel is a worm gear capable of engaging a worm screw. Engine is installed so that the axis of its gear wheel is actually parallel to the surface of the thermal head, which is in contact with the pressure roller, and perpendicular to the shaft of the clamping roller. Thermal printing mechanism also comprises a transmission shaft installed substantially parallel to axis of gear wheel of engine, wherein said transmission shaft has on one end a straight-toothed cylindrical gear wheel, installed so as to interact with driving straight-toothed cylindrical gear wheel, and at other end – worm screw, installed so that to engage with gear wheel of clamping roller.

EFFECT: thermal printing mechanism is proposed.
