Problems solved by technology
Due to the different maximum outer diameters of the carbon ribbon coils formed by winding the carbon ribbons of different specifications on the core barrel, the rewinding force required to drive the ribbon coils with different outer diameters to rotate is different, and the existing carbon ribbon recycling mechanism The rewinding force is determined by the compression spring 5'. When the specification of the compression spring 5' is determined, the rewinding force of the carbon ribbon recovery shaft is fixed. Therefore, the existing carbon ribbon recovery mechanism can only adapt to one specification of the carbon ribbon Recycling, its poor adaptability

A carbon ribbon recovery mechanism and a thermal transfer printer using same. The carbon ribbon recovery mechanism comprises a recovering component and a driving component. The recovering component comprises: a friction element (1), transmissively connected with the driving component and having a first and a second sleeves (13, 14) which are arranged coaxially; a first and a second torsion springs (4, 5), respectively held on the second sleeve (14) and the first sleeve (13) and having different torque value while overload sliding; a first supporting seat (2), used for spliced matching with a carbon ribbon core reel having a first external diameter, rotatably supported on the friction element (1) and connected with a first torsion beam (41) of the first torsion spring (4); a second supporting seat (3), used for spliced matching with a carbon ribbon core reel having a second external diameter, rotatably set in a center bore of the first supporting seat (2) and connected with a first torsion beam (51) of the second torsion spring (5). The second external diameter is less than the first one. The carbon ribbon recovery mechanism is able to provide different rewinding force for two kinds of the carbon ribbon coils having different external diameters, therefore enhancing the medium adaptability of the thermal transfer printer.
Description
technical field [0001] The present invention relates to a carbon ribbon recycling mechanism and a thermal transfer printer using the same. Background technique [0002] like Figure 1a As shown, a common thermal transfer printer includes a printing mechanism 100' and a ribbon mechanism 200', and a drive mechanism 300'. The printing mechanism 100' includes a tangent print head 11' and a printing rubber roller 12'; the carbon ribbon mechanism 200' includes a release shaft 21' and a recovery shaft 22', and the ribbon is drawn out from the release shaft 21' and passes through the print head 11' After being connected with the printing rubber roller 12', it is wound on the recovery shaft 22'; the driving mechanism 300' is respectively connected to the recovery shaft 22' and the printing rubber roller 12' in a transmission connection for driving the two to rotate. [0003] During printing, the unused carbon ribbon and the printing paper to be printed pass between the tangential pr...
