Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution for an ink supply device of a UV inkjet printer, including: a bottom plate 1, a ink storage cylinder 3 and an ink cartridge 5 arranged on the upper surface of the bottom plate 1 from left to right. A heat preservation cylinder 2 is sleeved outside the ink storage cylinder 3, and heating tubes 23 are symmetrically arranged inside the heat preservation cylinder 2. A second heat preservation sleeve 24 is also wrapped outside the heat preservation cylinder 2. A heat conduction rod 221 is arranged through the outside of the heat preservation cylinder 2, and a first heat preservation sleeve 22 is wrapped outside the heat conduction rod 221. The upper end of the ink storage cylinder 3 is threadedly connected with a connecting sleeve 4, and a motor 41 is installed on the upper surface of the connecting sleeve 4. The driving end of the motor 41 is connected with a rotating shaft 42. A first stirring rod 43 and a second stirring rod 44 are respectively arranged on the outside of the rotating shaft 42 from left to right. A first ink pumping pump 51 is also installed on the upper surface of the ink cartridge 5, and a second ink pumping pump 52 is installed on one side of the ink cartridge 5. This setting uses the heating tubes 23 inside the heat preservation cylinder 2 to heat the ink inside the ink storage cylinder 3, avoiding ink solidification and affecting the subsequent ink supply work of the UV inkjet printer. At the same time, the operation of the motor 41 will cause the first stirring rod 43 and the second stirring rod 44 outside the rotating shaft 42 to rotate, thereby achieving the purpose of stirring and heating the ink inside the ink storage cylinder 3 evenly.

[0023] As Figure 1 shown, the inlet of the first ink pumping pump 51 is connected with a first connecting pipe 511, and the outlet of the first ink pumping pump 51 is connected with a second connecting pipe 512. One end of the first connecting pipe 511 penetrates through the outside of the ink storage cylinder 3 and extends into the inside of the ink storage cylinder 3. The lower end of the second connecting pipe 512 penetrates through the upper surface of the ink cartridge 5 and extends into the inside of the ink cartridge 5. This setting uses the first ink pumping pump 51 to pump the ink inside the ink storage cylinder 3 through the first connecting pipe 511 and enter the inside of the ink cartridge 5 through the second connecting pipe 512, achieving the purpose of supplying ink to the inside of the ink cartridge 5.

[0024] As Figure 1 shown, the outlet of the second ink pumping pump 52 is connected with an ink outlet pipe 521, and the inlet of the second ink pumping pump 52 is connected with an ink pumping pipe. The ink pumping pipe is arranged inside the ink cartridge 5. This setting uses the second ink pumping pump 52 to pump the ink inside the ink cartridge 5 through the ink pumping pipe and discharge it outward through the ink outlet pipe 521, achieving the purpose of supplying ink to the UV inkjet printer.

[0025] As Figure 1 and Figure 2 shown, three groups of heat conduction rods 221 are symmetrically arranged outside the heat preservation cylinder 2, and one end of the heat conduction rod 221 penetrates through one side of the ink cartridge 5 and extends into the inside of the ink cartridge 5. This setting uses the heat conduction rod 221 to transfer the heated heat to the inside of the ink cartridge 5, achieving the purpose of heating the ink inside the ink cartridge 5.

[0026] As Figure 2 and Figure 3As shown, a heat-conducting adhesive 21 is also coated on the inner side of the heat-insulating cylinder 2. At least sixteen heating tubes 23 are symmetrically arranged inside the heat-insulating cylinder 2. This arrangement uses the heat-conducting adhesive 21 to transfer heat to the ink storage cylinder 3, achieving the purpose of heating the ink inside the ink storage cylinder 3.

[0027] As Figure 4 shown, the first stirring rod 43 and the second stirring rod 44 are arranged alternately outside the rotating shaft 42, and both the first stirring rod 43 and the second stirring rod 44 are provided with four. This arrangement uses the first stirring rod 43 and the second stirring rod 44 to rotate when the motor 41 works to drive the rotating shaft 42 to rotate, so that the first stirring rod 43 and the second stirring rod 44 rotate, achieving the purpose of uniformly stirring and heating the ink inside the ink storage cylinder 3.

[0028] As Figure 4 shown, a connecting rod 45 is connected to the lower end of the rotating shaft 42. A scraping plate 451 is installed at the end position of the upper surface of the connecting rod 45. The outer side of the scraping plate 451 is in contact with the inner wall of the ink storage cylinder 3. This arrangement uses the scraping plate 451 to scrape the ink on the inner wall of the ink storage cylinder 3, avoiding waste caused by its adhesion to the inner wall.

[0029] The working principle of the present utility model is as follows: When the ink supply device of the UV inkjet printer of the present utility model is in use, first, when the weather is cold, the heating tubes 23 inside the heat-insulating cylinder 2 can be powered on and started. After being powered on, the heat generated by heating is transferred to the inside of the ink storage cylinder 3 through the heat-conducting adhesive 21, achieving the purpose of heating the ink inside it. When heating, the motor 41 is started to work, which will cause the rotating shaft 42 to rotate, and the first stirring rod 43 and the second stirring rod 44 to rotate to stir the ink, so that the heating is uniform. At the same time, when the rotating shaft 42 rotates, the scraping plate 451 at the upper end of the connecting rod 45 can clean the inner wall of the ink storage cylinder 3, avoiding damage and waste caused by the adhesion of ink to the inner wall. After heating, the first ink pumping pump 51 can extract the ink inside the ink storage cylinder 3 through the first connecting pipe 511 and discharge it into the inside of the ink cartridge 5 through the second connecting pipe 512, so as to ensure the amount of ink inside the ink cartridge 5. Finally, the second ink pumping pump 52 can extract the ink inside the ink cartridge 5 and discharge it out through the ink outlet pipe 521 to supply ink for the UV inkjet printer, with good practicability.

[0030] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
