[0028] like Figure 1-5As shown, a UV printer ink supply device that facilitates ink cartridge replacement includes a positioning plate 3 and a cartridge cover 81. The positioning plate 3 is provided with a positioning mechanism that has a sleeve rod 5 to limit the movement of the cartridge body 80. The positioning mechanism includes a sleeve 4, which is interference-fitted with the sleeve rod 5. A spring 6 is sleeved on the sleeve rod 5. A triangular positioning plate 7 is fixedly connected to one side of the spring 6 and is engaged in the inclined groove 801.

[0029] The lid 81 is provided with a stirring mechanism that has a motor 9 to prevent ink sedimentation. The stirring mechanism includes a stirrer 13, and the rotating end of the motor 9 is fitted with the stirrer 13.

[0030] It also includes a UV printer body 1, which is composed of a horizontal linear module, a vertical linear module, and a vertical linear module. A print head 100 is bolted to the sliding end of the vertical linear module, and a placement box 2 is fixedly connected to the sliding end of the vertical linear module. The horizontal, vertical, and vertical linear modules of the UV printer body 1 enable the print head 100 to achieve three-dimensional movement in the horizontal, vertical, and vertical directions. At the same time, the ink cartridge 8 provides printing ink to the print head 100 through a guide tube. The above descriptions are all prior art and will not be elaborated further here.

[0031] Please see Figure 3 The four corners of the bottom surface of the placement box 2 are fixedly connected to guide ends 20. The interior of the placement box 2 is provided with a cavity, in which a box body 80 is placed. The box body 80 is placed from top to bottom in the placement box 2 and first passes through the four guide ends 20. The four guide ends 20 guide and limit the falling of the box body 80.

[0032] Please see Figure 2 The top surfaces of both sides of the placement box 2 are fixedly connected to positioning plates 3. The positioning plates 3 are horizontally fixedly connected to sleeves 4. The sleeves 4 have limit grooves 40. One end of the sleeve rod 5 is fixedly connected to a limit strip 50. The limit strip 50 is slidably connected to the limit groove 40. The spring 6 is located between the sleeve 4 and the triangular positioning plate 7. The function of the sliding limit strip 50 in the limit groove 40 is mainly to keep the sleeve rod 5 in a horizontal state so that the triangular positioning plate 7 can slide horizontally and will not rotate on its own.

[0033] Please see Figure 3 The top of the cartridge 80 has symmetrically arranged inclined grooves 801 on both sides, and a slot 800 is provided at the center of the top of the cartridge 80. A cover 81 is inserted into the slot 800, and a sealing ring is fitted at the bottom of the cover 81. The cartridge 80 and the cover 81 are combined to form an ink cartridge 8. The function of the sealing ring is to prevent leakage of the ink-containing cartridge 80 and to prevent external impurities from entering the cartridge 80.

[0034] Please see Figure 1 A bracket 10 is attached to the top of the cartridge cover 81. The bracket 10 is fixedly connected to the outer circumferential walls on both sides of the motor 9. A screw 11 is inserted into the bracket 10 and threaded into the cartridge cover 81. The cartridge cover 81 has a threaded hole. The screw 11 positions the motor 9 through the threaded hole. At the same time, the screw 11 can be unscrewed from the bolt hole to achieve the advantage of easy disassembly and assembly, thus facilitating its application to new ink cartridges 8.

[0035] Please see Figure 1 The stirrer 13 consists of a stirring rod and a stirring blade. The rotating end of the motor 9 passes through the top of the cover 81. The rotating end of the motor 9 and the stirring rod are horizontally connected by bolts 12. Both the rotating end of the motor 9 and the stirring rod have horizontal through holes. The bolts 12 pass through the through holes and connect the motor 9 and the stirring rod. At the same time, the bolts 12 can also be used to remove the stirrer 13 from the motor 9, so that it can be disassembled and reassembled for use on a new ink cartridge 8.

[0036] The implementation principle of the UV printer ink supply device for easy ink cartridge replacement according to an embodiment of this application is as follows:

[0037] The replacement ink cartridge 8 is placed from the guide end 20. The ink cartridge 8 falls from top to bottom onto the placement box 2. The ink cartridge 8 makes vertical contact with the inclined surface of the triangular positioning plate 7, which will cause the triangular positioning plate 7 to move towards the positioning plate 3. The triangular positioning plate 7 drives the sleeve rod 5 to move into the sleeve 4, while the spring 6 compresses and contracts. When the cartridge body 80 is placed at the bottom of the placement box 2, the inclined groove 801 is parallel to the triangular positioning plate 7. At this time, the triangular positioning plate 7 is inserted into the inclined groove 801 under the rebound of the spring 6. The triangular positioning plate 7 is inserted into the slot 800 by the rebound force of the spring 6, thereby locking the cartridge body 80.

[0038] The process of removing ink cartridge 8 from the placement box 2 is as follows: Hold the top of the box cover 81 and lift it upwards. As the ink cartridge 8 is lifted, the triangular positioning plate 7 of the box cover 81 will first slide out of the inclined groove 801. Then the triangular positioning plate 7 will continue to contact the side wall of the box body 80 until it is completely slid out and reset.

[0039] During the continuous ink ejection process from the print head 100 to the ink cartridge 8, in order to prevent sediment in the cartridge 80 from causing poor ink ejection and clogging, the motor 9 is turned on. The motor 9 drives the agitator 13 to stir the ink in the cartridge 80. The stirring mechanism can make the ink fully mixed, so that all the ink in the ink cartridge 8 can be effectively utilized, improving the ink utilization rate, extending the service life of the ink cartridge 8, and reducing the user's printing costs.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
