[0023] In the present invention, preferably, the bottom surface of the ribbon cassette lower shell 2 is snap-connected with the bottom cover 3 .

[0024] In the present invention, preferably, the supply-end tower spring 7 is in close contact with the side wall of the lower shell 2 of the ribbon cassette.

[0025] In the present invention, preferably, a damping torsion spring 9 is installed on the ribbon power gear shaft 10, and the damping torsion spring 9 is used to control the rotation speed of the recycling end ribbon shaft 6.

[0026] In the present invention, preferably, the damping torsion spring 9 is arranged on the ribbon power gear shaft 10, which is used to control the rotation speed of the ribbon recovery shaft so that the linear speed of the rotation of the ribbon recovery end is always the same as the paper output speed. Through the set ribbon power gear shaft 10 and the damping torsion spring 9 structure, the function of ribbon recovery stability is realized. The damping torsion spring 9 can ensure that the linear speed of the rotation of the ribbon recovery end is always the same as the paper output speed, thereby avoiding the relative slippage between the ribbon and the paper and ensuring the printing effect.

[0027] In the present invention, preferably, a paper bin is provided at the rear end of the ribbon cassette lower shell 2 for accommodating the label paper roll 4 .

[0028] In the present invention, preferably, a ribbon recovery bin is provided at the front end of the ribbon cassette upper shell 1 for accommodating recovered ribbons.

[0029] In the present invention, preferably, the ribbon recovery bin and the ribbon supply bin are connected by cantilevers on both sides, and the distance between the middle parts of the cantilevers is wider than the movement, so that the ribbon box can be installed on the printer from a vertical direction.

[0030] The compact structure is used to reduce the overall size of the printer. The utility model integrates the ribbon cartridge and the paper bin into one, and adopts a vertical installation method to optimize the space layout and reduce the overall size of the printer.

[0031] The working principle and usage process of the present invention are as follows: When in use, the user first loads the label paper roll 4 into the paper bin inside the upper shell 1 of the ribbon cassette, then mates the assembled upper shell with the lower shell, and installs the bottom cover 3 to complete the assembly of the ribbon cassette. Next, the user vertically installs the ribbon cassette on the printer, and uses the ribbon recovery bin at the front end of the ribbon cassette lower shell 2 to connect the ribbon supply shaft and the recovery end ribbon shaft 6 to the corresponding components of the printer. When the printer is working, the label paper roll 4 is fed out from the paper bin of the upper shell 1 of the ribbon cassette through the paper channel, and the ribbon supply shaft feeds the ribbon to the print head for printing. The printed ribbon enters the ribbon recovery bin through the ribbon recovery channel and is recovered by the recovery end ribbon shaft 6. The damping torsion spring 9 on the ribbon power gear shaft 10 can ensure that the linear speed of the ribbon recovery end is always the same as the paper output speed, avoiding relative slippage between the ribbon and paper and ensuring the printing effect. Because both the supply-end ribbon shaft 5 and the recycle-end ribbon shaft 6 are equipped with springs, when the ribbon is forced forward, the supply-end ribbon shaft 5 is compressed and rubs against the sidewall of the ribbon cassette lower shell 2, generating a ribbon tensioning force to prevent the ribbon from wrinkling during printing. At the same time, a ribbon power gear shaft 10 and a damping torsion spring 9 tightly fitted with the ribbon power gear shaft 10 are installed in the hole of the recycle-end ribbon shaft 6. When the ribbon power gear shaft 10 moves, the pins of the damping torsion spring 9 drive the recycle-end ribbon shaft 6 to rotate, generating a force that separates the ribbon from the paper, thereby achieving the effect of recovering the printed ribbon.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
