[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, the carriage mechanism in this embodiment includes a carriage frame 1, a carriage head 2, an ink cartridge 3, and an ink bag 4.

[0030] The headstock 2 is fixedly mounted on the carriage frame 1, and then performs printing work as the carriage frame 1 moves. The headstock 2 in this embodiment includes a main body 21 having a mounting cavity 211 and a cover 22 mounted on the main body 21, wherein the main body 21 is fixed on the carriage frame 1, and the cover 22 is openable and closable and is mounted on the mouth of the mounting cavity 211. In order to avoid the cover 22 from being lost, the cover 22 in this embodiment is rotatably connected to the main body 21, specifically, the cover 22 is connected to one of the side edges of the main body 21. In addition, a buckle 224 is rotatably connected to the cover 22, and a snap-on portion 212 for snapping the buckle 224 is provided on the main body 21. When the cover 22 needs to be snapped onto the main body 21, the cover 22 is rotated and operated, and the buckle 224 is deformed and snapped onto the snap-on portion 212 based on its own elasticity. Since the carriage head 2 needs to move when working, vibration is inevitable. In order to ensure the firmness of the cover body 22 on the main body 21, a torsion spring 225 is provided on the cover body 22 at a position corresponding to the connection of the buckle 224. The end of the torsion spring 225 is connected to the buckle 224, and has a tendency to pull the buckle 224 to rotate in the opposite direction of the buckling direction. That is, when the buckle 224 is buckled on the snap-on portion 212, based on the contact degree of the torsion spring 225 tightening the buckle 224 on the snap-on portion 212, the buckle 224 is prevented from being too loose relative to the snap-on portion 212 and opening.

[0031] The ink cartridge 3 is detachably arranged in the installation cavity 211 of the main body 21, that is, when the ink cartridge 3 needs to be installed, the cover 22 is operated to be opened relative to the main body 21, and then the ink cartridge 3 is placed, and then the cover 22 is closed, so that the buckle 224 on the cover 22 is buckled on the buckle 212 of the main body 21, thereby ensuring the stability of the ink cartridge 3 in the installation cavity 211. Of course, the stability of the ink cartridge 3 in the installation cavity 211 can also be further ensured by setting a relative limiting structure on the installation cavity 211 of the main body 21 and the ink cartridge 3. When the ink outlet on the ink cartridge 3 needs to be cleaned, the cover 22 is opened, and then the ink cartridge 3 is taken out from the installation cavity 211 of the main body 21 for cleaning.

[0032] The ink bag 4 is detachably arranged on the headstock 2, and the ink bag 4 is in fluid communication with the ink cartridge 3. In this embodiment, the ink bag 4 is detachably arranged in the cover 22. In order to facilitate the rapid installation of the ink bag 4, a mounting groove 221 for placing the ink bag 4 is provided in the cover 22. When installing, the ink bag 4 can be inserted into the mounting groove 221. This structure also facilitates the replacement of the ink bag 4.

[0033] Specifically, the lower part of the ink sac 4 is provided with an ink outlet 41 for docking with the ink cartridge 3. The ink outlet 41 in this embodiment is a tube body integrally connected to the ink sac 4. An opening 222 is provided on the lower surface of the cover 22 in an area corresponding to the ink outlet 41. An ink inlet is provided on the upper surface of the ink cartridge 3 corresponding to each ink sac 4. After the ink sac 4 is installed in the cover 22, the ink outlet 41 of the ink sac 4 passes through the opening 222 of the cover 22 and is just inserted into the ink inlet of the ink cartridge 3, thereby achieving communication with the ink cartridge 3 and supplying ink to the ink cartridge 3.

[0034] In order to ensure the firmness of the ink sac 4 installed on the cover 22, an elastic sheet 42 is provided on the side wall of the ink sac 4. The elastic sheet 42 is inclined outward from bottom to top relative to the side wall of the ink sac 4, and a limiting buckle 43 is provided on the elastic sheet 42. A limiting hole 223 is provided on the side wall of the cover 22 for the limiting buckle 43 to be inserted based on the elastic force of the elastic sheet 42. When installing the ink sac 4, the ink sac 4 is inserted from top to bottom into the installation groove 221 of the cover 22. As the ink sac 4 moves downward, the elastic sheet 42 is squeezed by the groove wall of the installation groove 221 and tightened toward the side wall of the ink sac 4 until the limiting buckle 43 of the elastic sheet 42 is inserted into the additional limiting hole 223 of the cover 22, and the ink sac 4 is just installed in place in the installation groove 221. At the same time, based on the elastic force of the elastic sheet 42, the stability of the ink sac 4 in the installation groove 221 is ensured. When the ink bag 4 needs to be taken out, the elastic sheet 42 is manually pressed toward the side wall of the ink bag 4 to make the limiting buckle 43 disengage from the limiting hole 223 , and the ink bag 4 is pulled upward to make the ink bag 4 escape from the installation groove 221 .

[0035] Usually, ink bags 4 of multiple colors are installed on the headstock 2, that is, the ink bags 4 include at least two. In order to facilitate the rapid installation of the ink bag 4 and ensure the stability of the ink bag 4 after installation in the installation groove 221, the cover body 22 is provided with installation grooves 221 matching the number of ink bags 4, and limiting ribs 2211 are provided in the installation grooves 221 along the installation direction of the ink bag 4. The side walls of the ink bag 4 are formed with limiting grooves 44 for the limiting ribs 2211 to be placed. When installing the ink bag 4 on the cover body 22, the limiting grooves 44 on the ink bag 4 are aligned with the limiting ribs 2211 on the cover body 22 and inserted into the installation grooves 221, thereby realizing rapid and stable installation of the ink bag 4 in the installation grooves 221.

[0036] When installing ink sacs 4 of multiple colors, different ink sacs 4 need to be installed at fixed positions. If the positions of ink sacs 4 of different colors are incorrectly arranged, the printing image will be affected. In order to ensure the accuracy of the installation of the positions of the ink sacs 4 of each color, the limiting ribs 2211 in each installation groove 221 are set at different positions relative to the side wall of the ink sac 4. The ink sac 4 is formed with multiple limiting grooves 44, and some limiting grooves 44 are filled with ribs 45. In this way, the position of the limiting ribs 2211 in each installation groove 221 matches the position of the limiting groove 44 on the corresponding ink sac 4, avoiding the problem of incorrect installation.

[0037] The carriage mechanism of the utility model disassembles the ink cartridge 3 in the mounting cavity 211 of the main body 21. Based on the arrangement structure of the ink cartridge 3, when cleaning the ink cartridge 3, it is only necessary to take the ink cartridge 3 out of the mounting cavity 211 of the main body 21 for cleaning, which is simple and convenient to operate. At the same time, based on the disassembly and cleaning of the ink cartridge 3, there is no need to set up an additional cleaning device in the carriage, which greatly reduces the cost of the carriage. In addition, without the need to set up a cleaning device, the structure of the carriage is simpler, which is also conducive to its more compact design.

[0038] The utility model also relates to an inkjet printer, comprising the above-mentioned carriage mechanism. The inkjet printer, which applies the above-mentioned carriage mechanism, has a simple structure and low cost.
