Description

Technical Field

[0001] The utility model relates to the field of printers, and more specifically to a ribbon shaft of a printer. Background Art

[0002] The ribbon shaft is the part inside the printer or typewriter that holds and supports the ribbon (usually a film or tape soaked in ink). The ribbon is constantly moved during the printing process by the rotation of the ribbon shaft, so that the ink on the ribbon is transferred to the paper, thereby achieving the function of printing or typing. The main functions of the ribbon shaft include fixing the ribbon, ensuring that the ribbon moves smoothly during the printing process, and collecting the ribbon after use;

[0003] In printers and typewriters, the ribbon shaft is one of the key components used to support and drive the movement of the ribbon. The ribbon shaft drives the ribbon by rotating, so that the ribbon moves continuously during the printing process, transferring the ink on the ribbon to the paper to achieve the function of printing or typing;

[0004] For example, patent (CN220662066U) discloses a ribbon shaft for a label printer, which is advantageous in preventing the ribbon from piling up due to the rotation of the ribbon shaft, thereby avoiding abnormalities of the printer caused by the accumulation of ribbons.

The vertical sliding plate 7 and the transverse moving plate 8 are slidably connected by the first inclined surface and the second inclined surface, so that the transverse movement of the transverse moving plate 8 enables the vertical sliding plate 7 to rise vertically, and the rise of the vertical sliding plate 7 enables the arc-shaped clamping plate 3 to rotate through the oblique rotating plate 6;

[0033] An arc-shaped support plate 5 is also fixed inside the transverse shaft body 1, and a plurality of gear blocks are evenly fixed on the outer side of the top of the arc-shaped support plate 5. A gear groove adapted to the gear block is opened inside the arc-shaped clamping plate 3. Through the arrangement of the gear block and the gear groove, the ribbon can be fixed between the arc-shaped clamping plate 3 and the arc-shaped support plate 5, so as to prevent the ribbon from being wound around the outer side of the transverse shaft body 1 when the transverse shaft body 1 rotates;

[0034] A transverse through hole is provided inside the transverse shaft body 1, and a transverse light rod 15 is located inside the transverse through hole and is slidably connected with the transverse shaft body 1 through the transverse through hole.

[0038] Here, the elastic characteristics of the vertical rigid spring 13 enable the vertical light rod 11 to slide inside the L-shaped support plate 9, and then enable the vertical sliding plate 7 to slide inside the L-shaped support plate 9. The sliding of the vertical sliding plate 7 enables the arc clamping plate 3 to rotate toward the arc support plate 5 through the oblique rotating plate 6, so that the ribbon can be fixed between the arc clamping plate 3 and the arc support plate 5.

[0039] When in use: the circular pulling block 4 is pulled, and the pulling of the circular pulling block 4 enables the transverse light rod 15 to move inside the transverse shaft body 1, and the movement of the transverse light rod 15 enables the transverse circular fixing block 16 to move, and the movement of the transverse circular fixing block 16 causes the transverse rigid spring 17 to contract under force, and the movement of the transverse light rod 15 enables the transverse moving seat 14 to move, and the movement of the transverse moving seat 14 enables the transverse moving plate 8 to move, and the movement of the transverse moving plate 8 enables the vertical sliding plate 7 to rise through the setting of the first inclined surface and the second inclined surface, and the rise of the vertical sliding plate 7 enables the arc clamping plate 3 to rotate through the oblique rotating plate 6, thereby causing a gap between the circular pulling block 4 and the arc supporting plate 5, so that the ribbon can be replaced;
