[0029] Implementation Method 1

[0030] like Figures 1 to 4 As shown, the utility model provides an ink cartridge 100 for a rotary printer, comprising an ink storage mechanism 110 and an ink output printing mechanism 120; the ink storage mechanism 110 has a plurality of ink storage chambers 1110 and a plurality of ink output holes 1113; the plurality of ink storage chambers 1110 are independently arranged inside the ink storage mechanism 110, and an ink storage chamber 1110 is used to store ink of one color; the ink output holes 1113 are arranged on the surface of the ink storage mechanism 110, and an ink output hole 1113 is connected to an ink storage chamber 1110; the ink output printing mechanism 120 is arranged on the ink storage mechanism 110 and can be connected to each ink output hole 1113, and can output ink to a printing carrier to print a mark.

[0031] In a specific implementation, multiple independent ink storage chambers 1110 are provided within the ink storage mechanism 110. Each ink storage chamber is dedicated to storing a single color of ink. Each ink storage chamber 1110 is equipped with an ink outlet 1113 communicating therewith. These ink outlets 1113 are located on the surface of the ink storage mechanism 110 and can supply inks of different colors to the ink outlet printing mechanism 120. As a result, the ink output by the ink outlet printing mechanism 120 is not a single color, but multiple colors. This enables the rotary printer to print using multiple colors of ink, thus meeting the demand for multi-color printing.

[0032] In this embodiment, the rotary printer can be conventional. There can be two ink storage chambers 1110 and two ink outlets 1113. The ink outlet printing mechanism 120 functions to discharge the ink in the ink storage chamber 1110 onto a printing substrate such as paper after the ink enters the ink outlet printing mechanism 120. It is understood that since the ink output onto the printing substrate such as paper has multiple colors, rather than just one, when these inks land on the printing substrate, they form a multi-colored print, thus satisfying the demand for multi-color printing.

[0033] According to one embodiment of the present invention, the ink printing mechanism 120 includes a plurality of connected print heads 121; each print head 121 has an ink inlet hole, an inkjet cavity and a plurality of inkjet holes; an ink inlet hole is connected to an ink outlet hole 1113, and the ink inlet hole can be connected to each inkjet hole of the corresponding print head 121 through the inkjet cavity.

[0034] In specific implementations, the ink-discharging printing mechanism 120 is further subdivided into multiple interconnected print heads 121, each of which has an ink inlet, an inkjet cavity, and multiple inkjet orifices. This structure means that each color of ink flows from the ink storage cavity 1110 through an independent ink outlet 1113 into the ink inlet of the corresponding print head 121, is then distributed through the inkjet cavity, and is ultimately precisely ejected onto the paper through the inkjet orifices. Since each print head 121 is responsible for outputting ink of a specific color, this design not only prevents mixing of colors, ensuring the purity and accuracy of printed colors, but also enables the printer to control the ejection of multiple colors of ink, achieving high-quality color printing.

[0035] In this embodiment, there may be two print heads 121 , and the two print heads 121 may be integrally formed. The print heads 121 may be conventional.

[0036] According to one embodiment of the present invention, the print head 121 is a thermal inkjet print head.

[0037] In specific implementations, thermal bubble jet print heads can be existing technology. Thermal bubble jet print heads generate heat by using a heating element near the nozzle (inkjet orifice), causing the ink in the inkjet cavity to rapidly heat and form bubbles. The pressure generated by the expanding bubbles squeezes the ink in the inkjet cavity through the inkjet orifice, thereby forming an imprint on the paper. This technology offers advantages such as fast response, high precision, and excellent color reproduction. Because each print head 121 is equipped with an independent ink inlet, inkjet cavity, and multiple inkjet orifices, and is able to communicate with the different colors of ink in the ink storage chamber 1110, the use of thermal bubble technology ensures that each color of ink is efficiently heated and precisely sprayed into the designated location, achieving clear and detailed color printing. Furthermore, thermal bubble jet print heads are compact, easy to maintain, and relatively low in cost. This not only improves the performance of the entire ink cartridge 100, but also makes it more economical and practical to meet user needs. Therefore, the use of thermal bubble jet print heads further enhances the stability and color rendering of rotary printers during multi-color printing.

[0038] According to one embodiment of the present invention, the rotary printer includes a drive motor 200; the drive motor 200 has an output shaft 210; the ink cartridge 100 also includes a connecting column 130 for connecting the output shaft 210; the connecting column 130 is arranged on the ink storage mechanism 110; each ink outlet hole 1113 is located at one end of the ink storage mechanism 110 away from the drive motor 200.

[0039] In specific implementation, the drive motor 200 is equipped with an output shaft 210, and the ink cartridge 100 is connected to this output shaft 210 via a connecting post 130. The connecting post 130 is fixed to the ink reservoir 110, ensuring that the entire ink cartridge 100 can rotate synchronously with the rotation of the drive motor 200. This mechanical structure enables the ink cartridge 100 to perform precise and stable rotational motion, allowing the ink outlet 1113 located at the end of the ink reservoir 110 facing away from the drive motor 200 to accurately spray ink at a designated location on the paper.

[0040] In this embodiment, the ink storage mechanism 110 includes a bottom shell 111, a partition structure 112, and a top cover 113. The bottom shell 111 has a cavity 1111 and an opening 1112 that communicates with the cavity 1111. The cavity 1111 is located within the bottom shell 111. The opening 1112 is located at the top of the bottom shell 111. The ink outlet holes 1113 are located at the bottom of the bottom shell 111. The partition structure 112 is disposed within the cavity 1111 and can divide the cavity 1111 into multiple ink storage chambers 1110. The top cover 113 is disposed over the opening 1112. The connecting posts 130 are disposed on the top cover 113 and / or the bottom shell 111. Each print head 121 is disposed at the bottom of the bottom shell 111.

[0041] In a specific embodiment, the bottom shell 111 has a cavity 1111 within it, an opening 1112 at the top, and multiple ink outlet holes 1113 at the bottom. These ink outlet holes 1113 directly connect to their respective independent ink storage chambers 1110, allowing different colors of ink to be stored separately without interfering with each other. A partition structure 112 is located within the cavity 1111 of the bottom shell 111, dividing the entire cavity 1111 into multiple independent ink storage chambers 1110, each storing a specific color of ink. This design prevents the various colors of ink from mixing, thereby ensuring color purity and accuracy during printing. A top cover 113 covers the opening 1112 at the top of the bottom shell 111, not only protecting the internal structure from external contamination but also providing a seal to prevent ink volatilization or leakage. Furthermore, a connecting post 130 is provided on the top cover 113 and / or the bottom shell 111 and is connected to the output shaft 210 of the drive motor 200, allowing the entire ink cartridge 100 to rotate with the rotation of the motor.

[0042] According to one embodiment of the present invention, the partition structure 112 has a setting hole 1121 extending along the axial direction O of the bottom shell 111, the setting hole 1121 is located at the center of the cavity 1111, and passes through both ends of the partition structure 112 along the axial direction O of the bottom shell 111, so that the bottom of the setting hole 1121 is connected to the bottom of the cavity 1111; the top of the top cover 113 has an avoidance hole 1131; the connecting column 130 is embedded in the setting hole 1121 and passes through the avoidance hole 1131, and the connecting column 130 is sealed and connected to the periphery of the avoidance hole 1131.

[0043] In practice, this design provides a through-channel (hole 1121) for the connecting post 130. The shape of hole 1121 matches the shape of the connecting post 130, allowing the connecting post 130 to be securely embedded therein. The further the connecting post 130 is inserted, the greater the contact area between the connecting post 130 and the wall of the through-channel, thereby making the connection between the two more secure. The through-channel 1131 on the top cover 113 not only allows the connecting post 130 to pass through, but also forms a sealed connection between its periphery and the connecting post 130, ensuring the sealing of the entire ink cartridge 100 during rotation, preventing ink leakage or external dust from entering and affecting print quality.

[0044] According to one embodiment of the present invention, the output end of the output shaft 210 has an embedding hole; the connecting column 130 can be embedded in the embedding hole.

[0045] In practice, this embedded connection ensures a tight fit and stable connection between the ink cartridge 100 and the drive motor 200, allowing the entire ink cartridge 100 to rotate smoothly and accurately when the drive motor 200 rotates. This not only improves power transmission efficiency but also reduces printing deviation or jitter caused by an unstable connection, thereby ensuring high-precision positioning during the printing process. Furthermore, the embedded design simplifies installation, making it easier for users to replace ink cartridges 100 or maintain the device.

[0046] According to one embodiment of the present invention, there are two ink storage chambers 1110 , two ink outlet holes 1113 and two print heads 121 .

[0047] In a specific implementation, there are two ink storage chambers 1110, two ink outlet holes 1113, and two print heads 121. This configuration means that the interior of the ink cartridge 100 is divided into two independent ink storage chambers 1110, each for storing a different color of ink and connected to a corresponding print head 121 via an independent ink outlet hole 1113.

[0048] In this embodiment, the volumes of the ink storage chambers 1110 may be the same or different, and the specific volumes may be set according to actual needs.

[0049] Implementation Method 2

[0050] The present invention also provides a rotary printer, comprising: a drive motor 200 having an output shaft 210; the ink cartridge 100 of the above embodiment, the output shaft 210 being connected to the ink cartridge 100; and a control mechanism electrically connecting the drive motor 200 and the ink cartridge 100, capable of controlling the rotation of the drive motor 200 and controlling the ink discharge of the ink cartridge 100.

[0051] In a specific implementation, the drive motor 200 is equipped with an output shaft 210, which is connected to the ink cartridge 100 via this output shaft 210, allowing the ink cartridge 100 to rotate as the drive motor 200 rotates. The control mechanism is responsible for electrically connecting the drive motor 200 and the ink cartridge 100. It not only controls the rotation speed and direction of the drive motor 200, but also precisely controls the ink discharge process in the ink cartridge 100, ensuring that the ink discharge printing mechanism 120 (print nozzle 121) ejects the appropriate color of ink onto the paper at the correct time. The specific structure, operating principle, and beneficial effects of the ink cartridge 100 are the same as those in the first embodiment and will not be repeated here.

[0052] According to one embodiment of the present invention, it also includes a shell and a vibration sensor; the drive motor 200, the ink cartridge 100, the control mechanism and the vibration sensor are accommodated in the shell; the vibration sensor can detect the vibration value of the shell; the control mechanism controls the drive motor 200 and the ink cartridge 100 to turn on when the vibration value is greater than a preset vibration value.

[0053] In specific implementation, the vibration sensor can monitor the vibration of the shell in real time. When the detected vibration value exceeds the preset safety threshold, the control mechanism will trigger the drive motor 200 to start and control the ink cartridge 100 to start discharging ink for printing. This design means that the user can activate the rotary printer by knocking on the desktop or other means to generate sufficient vibration, thereby realizing a unique print start mechanism. By introducing the vibration sensor and its linkage function with the control mechanism, the rotary printer can automatically enter the working state after detecting a sufficiently large external vibration, which not only enhances the interactivity and flexibility of the device, but also may expand the application range of the printer.

[0054] In this embodiment, the shell can be a vertically arranged cylindrical structure with a closed upper end and an opening 1112 at the lower end. The two print heads 121 of the ink cartridge 100 can be located at the opening 1112 at the lower end of the shell, so that the two print heads 121 can spray ink from the opening 1112 onto a printing carrier such as paper.

[0055] Working principle:

[0056] First, place a printing substrate such as paper on the table, then place the rotary printer on the printing substrate such as paper, and make the lower end opening 1112 of the rotary printer shell cover the position where the mark is to be printed, then knock on the table hard. At this time, the table will vibrate, and when the table vibrates, the shell will also vibrate. At this time, the vibration sensor can detect the vibration. When the vibration value is greater than the preset vibration value, the rotary printer can start printing.

[0057] The above are only several embodiments of the present invention. Those skilled in the art may make various changes or modifications to the embodiments of the present invention based on the contents disclosed in the application documents without departing from the spirit and scope of the present invention.
