Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to an ink cartridge that reduces the generation of air bubbles. Background Technology

[0002] An ink cartridge is a device used to store and supply ink in the printing industry. It is connected to the ink delivery system of printing equipment via an ink outlet. When the equipment needs ink, the ink in the cartridge flows out from the outlet under the action of pressure difference or other driving mechanisms. It is then distributed onto the printing medium through the ink delivery pipes or nozzle components to form the required text, images, or patterns. During this process, the sealed structure of the ink cartridge ensures that the ink will not leak or be contaminated by the external environment during storage and supply. At the same time, the parameters such as the amount of ink and pressure inside the cartridge must be matched with the operating requirements of the equipment to ensure the stability and continuity of ink supply.

[0003] A search revealed Chinese patent publication number CN217319774U, which discloses a quick-release ink cartridge. The cartridge includes a box body with a cavity for holding ink and a cover for sealing the cavity. A guide portion is provided at one end of the box body near the cover for sliding the cover, allowing the cover to slide relative to the box body and seal or move away from the cavity. When the cover seals the cavity, the box body and cover are magnetically connected. According to the ink cartridge provided in the above embodiment, when the ink cartridge is in operation, the box body is magnetically connected to the cover to seal the ink within the cavity. When the ink cartridge needs to be disassembled, a force can be applied to the cover to overcome the magnetic force between the box body and the cover, allowing the cover to slide relative to the guide portion. Compared to the prior art, the ink cartridge provided in this embodiment is easier to disassemble; however, in actual use, during prolonged use, uneven ink flow and air ingress during extraction can cause air bubbles to form inside the ink cartridge, affecting print quality and stability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an ink cartridge that reduces the generation of air bubbles. It aims to improve the problem in the prior art where uneven ink flow and air mixing during long-term use lead to air bubbles inside the ink cartridge, thus affecting print quality and stability.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an ink cartridge for reducing bubble generation, comprising a shell, a servo motor fixedly connected to the bottom of the shell, a rotating column fixedly connected to the output end of the servo motor, rotating rods rotatably connected to the left and right sides of the inner top wall of the shell, drive bevel gears fixedly connected to the bottom ends of the outer walls of the rotating column and the two rotating rods, fixing sleeves fixedly connected to the left and right ends of the rear side of the inner wall of the shell, rotating rods rotatably connected to the inner walls of the fixing sleeves, driven bevel gears fixedly connected to the left and right ends of the rotating rods, the drive bevel gears meshing with the driven bevel gears, multiple connecting plates fixedly connected to the outer walls of the rotating column and the two rotating rods, a stirring blade fixedly connected to one side of the connecting plate, an injection valve connected to the right side of the shell, and a spray mechanism provided on the rear side of the shell.

[0006] The above technical solution enables the rotating column and the drive bevel gear to rotate synchronously when the servo motor is started. Under the meshing connection between the drive bevel gear and the corresponding driven bevel gear, the two rotating rods complete the rotation, and then multiple stirring blades fixed by the connecting plate rotate synchronously, which enables uniform mixing of ink, reduces the air bubble content in the ink, and improves printing quality.

[0007] As a further description of the above technical solution: The spraying mechanism includes a micro spray pump, the front of which is fixedly connected to the rear side of the housing. The left end of the micro spray pump is connected to an extraction tube, the front end of which is connected to the inner top of the housing. The rear side of the micro spray pump is connected to a delivery tube, the top end of which is connected to a spray head. A locking groove is provided on the top rear side of the housing, and the front side of the spray head engages with the locking groove. Connecting blocks are fixedly connected to both the left and right sides of the spray head, and bolts are threaded to the rear side of the connecting blocks. The front end of the bolts is connected to the rear side of the housing.

[0008] The above technical solution enables the ink to circulate from bottom to top when it is extracted from the bottom, thus forming a multi-layered three-dimensional mixing effect. This prevents ink sedimentation and allows the spray head to be disassembled from the rear of the housing by rotating the bolt, thereby enabling unclogging and maintenance of the spray head and improving its flexibility.

[0009] As a further description of the above technical solution: The spraying mechanism also includes two rubber rings, the inner walls of which are respectively fixedly connected to the middle of the bolt.

[0010] The above technical solution reduces the rotational damage to the connecting block caused by the bolts, thanks to the connection of the rubber ring.

[0011] As a further description of the above technical solution: A control switch is fixedly connected to the front right end of the housing, and the control switch is electrically connected to the servo motor and the micro spray pump respectively.

[0012] The above technical solution enables the device to be turned on and off by connecting the control switch.

[0013] As a further description of the above technical solution: Both the upper and lower sides of the spray head are fixedly connected with sealing gaskets, and the outer walls of both sealing gaskets are designed to be smooth.

[0014] The above technical solution improves the sealing performance when the spray head is connected to the locking groove by means of a sealing gasket.

[0015] As a further description of the above technical solution: A rubber ring is fixedly connected to the top of the outer wall of the delivery pipe, and the front side of the rubber ring is fixedly connected to the rear side of the spray head.

[0016] The above technical solution improves the protection effect at the connection of the conveying pipe by using rubber rings.

[0017] As a further description of the above technical solution: An observation window is fixedly connected to the front right end of the outer casing, and a sealing ring is fixedly connected to the outer wall of the injection valve.

[0018] The above technical solution enables the observation of the ink level inside the ink cartridge through the connection of the observation window.

[0019] As a further description of the above technical solution: The bottom wall of the outer shell is fixedly connected to the left and right sides with protective frames, and the bottom front and rear sides of the protective frames are fixedly connected to corner protectors.

[0020] The above technical solution enables the protection of the bottom of the ink cartridge through the connection of the protective frame and corner protectors.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the servo motor is started to drive the rotating column to rotate. Under the meshing connection of the driving bevel gear and the corresponding driven bevel gear, the two rotating rods rotate synchronously, and then multiple stirring blades rotate synchronously. This enables the ink at the top of the inner shell to be mixed evenly, reducing the air bubble content in the ink, improving the printing quality, and avoiding a decrease in stability.

[0022] 2. In this utility model, the micro spray pump is activated to extract ink from the bottom, and then the ink is circulated from bottom to top by the output of the spray head, thus forming a multi-layer three-dimensional mixing effect. This prevents ink sedimentation and extends the service life of the ink cartridge. When the spray head is inspected, the spray head can be disassembled from the back of the housing by rotating the bolt, so that the spray head can be unblocked and maintained.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an ink cartridge for reducing air bubble formation, comprising a housing 1, a servo motor 3 fixedly connected to the bottom of the housing 1, a rotating column 4 fixedly connected to the output end of the servo motor 3, and the rotating column 4 rotating when the servo motor 3 is started. Rotating rods 5 are rotatably connected to the left and right sides of the inner top wall of the housing 1. Drive bevel gears 6 are fixedly connected to the bottom ends of the outer walls of the rotating column 4 and the two rotating rods 5. Fixing sleeves 7 are fixedly connected to the left and right ends of the rear side of the inner wall of the housing 1, so that the rotating rods 8 can rotate synchronously through the rotation of the driven bevel gears 9 under the connection of the fixing sleeves 7. A rotating rod 8 is rotatably connected to the wall. A driven bevel gear 9 is fixedly connected to both the left and right ends of the rotating rod 8. A driving bevel gear 6 meshes with the driven bevel gear 9. Under the rotation of the driving bevel gear 6, the two rotating rods 5 rotate synchronously with the rotating column 4. Multiple connecting plates 10 are fixedly connected to the outer walls of the rotating column 4 and the two rotating rods 5. A stirring blade 11 is fixedly connected to one side of the connecting plate 10, so that the multiple stirring blades 11 can mix the ink evenly. An injection valve 12 is connected to the right side of the outer shell 1. Ink can be injected into the ink cartridge through the injection valve 12. A spray mechanism 2 is provided on the rear side of the outer shell 1. Specifically, by starting the servo motor 3, the rotating column 4 can be driven to rotate. While the rotating column 4 is rotating, the driving bevel gear 6 and the corresponding driven bevel gear 9 are meshed together to ensure the transmission of power. The rotating rod 8 rotates inside the fixed sleeve 7. Due to the stable connection of the fixed sleeve 7, the rotating rod 8 can ensure that the driving bevel gears 6 on the left and right sides can rotate synchronously under the rotation of the corresponding driven bevel gears 9. This ensures that the rotating column 4 can rotate in a consistent manner with the two rotating rods 5, thereby enabling the multiple stirring blades 11 to stir synchronously through the connecting plate 10. During the synchronous rotation of the stirring blades 11, the ink at the top of the inner shell 1 can be evenly mixed, thereby reducing the air bubble content in the ink. Reducing air bubbles not only improves the quality of the ink, but also improves the printing quality when using the ink in actual use.

[0027] Reference Figure 1 , Figure 3 and Figure 5The spray mechanism 2 includes a micro spray pump 201. The front side of the micro spray pump 201 is fixedly connected to the rear side of the housing 1. The left end of the micro spray pump 201 is connected to an extraction tube 202. The front end of the extraction tube 202 is connected to the top of the interior of the housing 1. Through the connection of the extraction tube 202, the micro spray pump 201 can extract the ink at the bottom. The rear side of the micro spray pump 201 is connected to a delivery tube 203. The top end of the delivery tube 203 is connected to a spray head 204. Then the ink at the bottom is output through the spray head 204 to achieve a multi-layer three-dimensional mixing effect. The top of the rear side of the housing 1 is provided with a locking groove 205. The front side of the spray head 204 is engaged with the locking groove 205. The left and right sides of the spray head 204 are fixedly connected to connecting blocks 206. The rear side of the connecting blocks 206 is threaded with bolts 207. By rotating the bolts 207, the spray head 204 can be disassembled and maintained, thereby improving its flexibility. The front end of the bolts 207 is connected to the rear side of the housing 1. Specifically, by activating the micro spray pump 201, ink from the bottom of the ink cartridge can be drawn through the extraction tube 202. Under the operation of the micro spray pump 201, the ink at the bottom can be effectively sprayed out through the spray head 204, ensuring that the ink can circulate upwards from the bottom, thereby achieving multi-layer three-dimensional mixing of the ink, effectively preventing ink sedimentation, and thus extending the overall service life of the ink cartridge. When it is necessary to inspect and clean the spray head 204, the spray head 204 and the connecting block 206 can be disassembled from the rear side of the outer casing 1 by turning the bolt 207, which improves the maintenance flexibility of the spray head 204 and makes maintenance work simpler and faster.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The spray mechanism 2 also includes two rubber rings 208, the inner walls of which are fixedly connected to the middle of bolts 207 respectively; a control switch 14 is fixedly connected to the front right end of the housing 1, and the control switch 14 is electrically connected to the servo motor 3 and the micro spray pump 201 respectively; sealing gaskets 210 are fixedly connected to the upper and lower sides of the spray head 204, and the outer walls of the two sealing gaskets 210 are both designed to be smooth. Specifically, the rubber ring 208 can reduce the rotational damage of the bolt 207 to the connecting block 206. The control switch 14, which is electrically connected to the servo motor 3 and the micro spray pump 201 respectively, can turn the equipment on and off. The two sealing gaskets 210 can improve the sealing effect between the spray head 204 and the locking groove 205.

[0029] Reference Figure 1 , Figure 2 and Figure 5A rubber ring 209 is fixedly connected to the top of the outer wall of the delivery pipe 203, and the front side of the rubber ring 209 is fixedly connected to the rear side of the spray head 204; an observation window 15 is fixedly connected to the right front end of the outer casing 1, and a sealing ring 13 is fixedly connected to the outer wall of the injection valve 12; a protective frame 16 is fixedly connected to both the left and right sides of the bottom wall of the outer casing 1, and corner protectors 17 are fixedly connected to the front and rear sides of the bottom of the protective frame 16. Specifically, the rubber ring 209 protects the connection at the top of the delivery tube 203, the observation window 15 allows for observation of the remaining ink level, and the protective frame 16 and corner protectors 17 protect the bottom of the ink cartridge, thus improving its service life.

[0030] Working principle: When in use, the servo motor 3 is started, which drives the rotating column 4 to rotate. Under the meshing connection of the driving bevel gear 6 and the corresponding driven bevel gear 9, the rotating rod 8 rotates inside the fixed sleeve 7. Thus, the driving bevel gears 6 on the left and right sides can rotate synchronously under the rotation of the corresponding driven bevel gear 9, so that the rotating column 4 can rotate synchronously with the two rotating rods 5. In turn, multiple stirring blades 11 can perform stirring work synchronously through the connecting plate 10, so that the stirring blades 11 can uniformly mix the ink at the top of the inner shell 1, thereby reducing the air bubble content in the ink and improving the printing quality when using the ink. Furthermore, by activating the micro spray pump 201, the ink at the bottom can be drawn through the extraction tube 202. Under the operation of the micro spray pump 201, the ink at the bottom can be sprayed out through the spray head 204, allowing the ink to circulate from bottom to top. This creates a multi-layered three-dimensional mixing effect, preventing ink sedimentation and extending the service life of the ink cartridge. When inspecting and cleaning the spray head 204, the spray head 204 and the connecting block 206 can be disassembled from the rear of the housing 1 by rotating the bolt 207, thus improving the flexibility of the spray head 204.
