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

Embodiment Construction
[0064] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0065] figure 2 It is a schematic cross-sectional view of an embodiment of the thermal transfer printer provided by the present invention, image 3 It is a structural schematic diagram of an embodiment of the thermal transfer printer provided by the present invention when the upper cover is opened. Such as figure 2 , image 3 As shown, the thermal transfer printer includes a base 100 , an upper cover 200 , a ribbon holder 300 , a printing mechanism 400 , a ribbon mechanism 500 , and a paper roll support mechanism 600 .
[0066] The upper cover 200 and the ribbon holder 300 are pivotally connected to the base 100 through the pivot shaft 101, and can be rotated to open or close relative to the base 100. Along the opening and closing direction of the upper cover 200, the ribbon holder 300 is located between the base 100 and the upper cover 200. betw...

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 invention relates to a ribbon recovery mechanism and a thermal transfer printer using the mechanism. Background technique [0002] Such as Figure 1a As shown, a common thermal transfer printer includes a printing mechanism 100', a ribbon mechanism 200', and a driving mechanism 300'. Among them, the printing mechanism 100' includes a tangential printing head 11' and printing rubber roller 12'; the carbon ribbon mechanism 200' includes a distribution shaft 21' and a recovery shaft 22', and the carbon ribbon is drawn out from the distribution shaft 21' and passes through the printing head 11' Between the printing rubber roller 12', it is wound on the recovery shaft 22'; the driving mechanism 300' is respectively connected with the recovery shaft 22' and the printing rubber roller 12', and is used to drive the two to rotate. [0003] When printing, the unused carbon ribbon and the printing paper to be printed pass between the tangential print head 11...
