Description

Technical Field

[0001] This utility model relates to the field of printer technology, and more specifically to a color inkjet printer core and printer thereof. Background Technology

[0002] Traditional color inkjet printers often lack integrated internal structures, with key components being scattered and independently configured. This means that when producing printers with different casing styles, each component must be individually assembled with the printer casing, requiring precise positioning and fixation. This increases the complexity of the assembly process and significantly extends assembly time. Furthermore, because the components are assembled separately, the precision of their fit is difficult to guarantee, easily leading to problems such as poor paper feeding and ink cartridge jamming, affecting the overall operational stability of the printer.

[0006] The present invention is further configured such that: the ink cartridge rotating mechanism includes a second gear set disposed on the base, and a rotating motor mounted on the base; a gear disk is rotatably connected to the base; the output shaft of the rotating motor and the gear disk are both connected to the second gear set for transmission, so that the rotating motor drives the gear disk to rotate through the second gear set; and the ink cartridge is fixed on the gear disk.

[0007] The present invention is further configured such that: mounting grooves are provided on both sides of the base, and bushings are respectively fitted on both ends of the rubber roller, and the bushings are fixed in the mounting grooves.

[0008] The present invention is further configured such that: limiting plates are respectively provided at both ends of the rubber roller, the limiting plates are attached to the base, and the limiting plates are used to limit the axial displacement of the rubber roller.

[0009] The present invention is further configured such that: a mounting bracket is fixed on the rotating shaft of the gear disc, and the ink cartridge is detachably connected to the mounting bracket.

[0010] The present invention is further configured such that: a first magnet is provided on the mounting bracket, and a second magnet is provided on the ink cartridge to cooperate with the first magnet, and the ink cartridge is magnetically fixed to the mounting bracket.

[0011] The present invention is further configured such that: one end of the base has an arc surface, the arc surface is coaxially arranged with the rotation axis of the gear disk, and the nozzle of the ink cartridge protrudes outside the arc surface and rotates along the arc surface.

[0012] In addition, this utility model also proposes a printer, including the aforementioned color inkjet printer core.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] 1.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0023] A type of color inkjet printer cartridge, such as Figures 1 to 3 As shown, the printer includes a base 1 with multiple threaded holes on its edge, allowing it to be fixed to the printer housing with screws. A paper feeding mechanism is mounted on the base 1, and a rubber roller 2 is rotatably connected to it. The paper feeding mechanism drives the rubber roller 2 to rotate, thus enabling it to transport paper. An ink cartridge 3 rotation mechanism is also mounted on the base 1, with the ink cartridge 3 fixed to it. This mechanism drives the ink cartridge 3 to rotate; as the paper is fed forward, the ink cartridge 3 rotates while the nozzle 16 ejects ink to achieve printing.

[0024] Specifically, the paper feeding transmission mechanism includes a first gear set 4 mounted on the base 1, and a paper feeding motor 5 mounted on the base 1. A driven gear 6 is coaxially fixed to one end of the rubber roller 2. The output shaft of the paper feeding motor 5 and the driven gear 6 are both connected to the first gear set 4, so that the paper feeding motor 5 drives the rubber roller 2 to rotate through the first gear set 4. A gear is also coaxially fixed on the output shaft of the paper feeding motor 5. When the paper feeding motor 5 is running, the output shaft drives the first gear set 4 to rotate through the gear.

[0025] The base 1 has mounting grooves 10 on both sides, and bushings 11 are fitted on both ends of the rubber roller 2. The rubber roller 2 and the bushings 11 rotate relative to each other, and the bushings 11 are fixed in the mounting grooves 10, so that the rubber roller 2 can rotate on the base 1. The mounting groove 10 is formed by an elastic arm with a notch at the top. The bushings 11 are pressed into the mounting groove 10 from the notch at the top. The inner wall of the mounting groove 10 is arc-shaped and fits against the peripheral side wall of the circular bushing 11.

[0026] Limiting plates 12 are provided at both ends of the rubber roller 2. A notch is provided on the base 1. The limiting plates 12 fit against the inner wall of the notch on the base 1. The limiting plates 12 are used to limit the axial displacement of the rubber roller 2 and improve the stability of the rubber roller 2. The limiting plates 12 can be integrally formed with the bushing 11.

[0027] Specifically, the ink cartridge 3 rotation mechanism includes a second gear set 7 mounted on the base 1, and a rotary motor 8 mounted on the base 1. A gear disk 9 is rotatably connected to the base 1. The output shaft of the rotary motor 8 and the gear disk 9 are both connected to the second gear set 7, so that the rotary motor 8 drives the gear disk 9 to rotate through the second gear set 7. A gear is also coaxially fixed on the output shaft of the rotary motor 8. When the rotary motor 8 is running, the output shaft drives the second gear set 7 to rotate through the gear. The ink cartridge 3 is fixed on the gear disk 9, and when the gear disk 9 rotates, the ink cartridge 3 rotates together with the gear disk 9.

[0028] like Figures 3 to 5 As shown, specifically, a mounting bracket 13 is fixed on the rotating shaft 15 of the gear disk 9, and the ink cartridge 3 is detachably connected to the mounting bracket 13. A first magnet 18 is embedded in the mounting bracket 13, and a second magnet 19 that cooperates with the first magnet 18 is fixed on the side of the ink cartridge 3 facing the mounting bracket 13. The ink cartridge 13 is fixed by attracting the second magnet 19 to the first magnet 18, which facilitates disassembly and assembly and makes it convenient for users to replace the ink cartridge later. The first magnet 18 is respectively provided on the left and right sides of the mounting bracket 13, and the second magnet 19 is also fixed on the left and right sides of the ink cartridge 13 respectively.

[0029] One end of the base 1 has an arc surface 14, which is coaxially arranged with the rotation shaft 15 of the gear disk 9. The nozzle 16 of the ink cartridge 3 is located at the end of the ink cartridge 3 away from the gear disk 9. The nozzle 16 of the ink cartridge 3 protrudes outside the arc surface 14 and rotates along the arc surface 14, so that the nozzle 16 of the ink cartridge 3 will not be blocked by the base 1 when rotating.

[0030] The base 1 has several protruding conveyor ribs 17, which extend along the paper conveying direction. The conveyor ribs 17 reduce the friction between the paper and the surface of the base 1, making the paper conveying smoother. The rubber roller 2 is located on the same side of the base 1 as the conveyor ribs 17, and the ink cartridge 3 is located on the other side of the base 1, with the nozzle 16 of the ink cartridge 3 facing the side of the conveyor ribs 17.

[0031] This embodiment also proposes a printer, including a housing, in which the aforementioned color inkjet printer core is installed.

[0032] The working process of this utility model is as follows:

[0033] The paper feeding motor 5 drives the rubber roller 2 to rotate through the first gear set 4. The rubber roller 2 adheres to the paper and conveys the paper towards the nozzle 16 of the ink cartridge 3. The rotating motor 8 drives the gear disk 9 to rotate through the second gear set 7, thereby moving the ink cartridge 3 along the arc surface 14. At the same time, the nozzle 16 of the ink cartridge 3 sprays ink onto the paper to achieve printing.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.

[0035] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
