[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] Refer to Figures 1-7 , an ink injection device for a coding machine provided in this embodiment includes an ink storage tank 1. The top of the ink storage tank 1 is provided with a feed inlet 3 through a tank cover 2. A stirring mechanism 4 is provided near the bottom of the ink storage tank 1. A filter screen 6 is provided on the ink storage tank 1 through a fixed cylinder 5. An ink supply component 7 is provided on one side of the ink storage tank 1. The stirring mechanism 4 can improve the fluidity of the ink in the ink storage tank 1 and clean the particles filtered on the filter screen 6.

[0027] In the present utility model, the ink for coding is first injected into the ink storage tank 1 through the feed inlet 3 on the tank cover 2 for storage. During coding, the stirring mechanism 4 is started to stir the ink in the ink storage tank 1, thereby improving the fluidity of the ink and avoiding the precipitation of the ink in the ink storage tank 1. The ink is pumped out through the ink supply component 7 and sent to the inkjet mechanism of the coding machine. During this process, the ink passes through the filter screen 6 in the fixed cylinder 5 to filter out impurities and particles in the ink. The stirring mechanism 4 can scrape off the impurities and particles filtered on the filter screen 6 while stirring the ink, thereby maintaining the smoothness of the filter screen 6 and avoiding blockage of the filter screen 6.

[0028] Specifically, as Figure 2 and Figure 3 shown, the stirring mechanism 4 includes a reduction motor 42 provided on the ink storage tank 1 through a mounting frame 41. A connecting shaft 43 is provided at the output end of the reduction motor 42. A stirring rod 44 located inside the ink storage tank 1 is provided on the connecting shaft 43.

[0029] Among them, when the ink in the ink storage tank 1 is stored for a long time, the reduction motor 42 on the mounting frame 41 drives the connecting shaft 43 to rotate, and then the stirring rod 44 on the connecting shaft 43 rotates. The rotating stirring rod 44 stirs the ink, thereby improving the fluidity of the ink and preventing the ink from precipitating.

[0030] Specifically, as Figures 2-4 shown, the stirring mechanism 4 further includes a scraping net assembly 45 arranged on the connecting shaft 43. The scraping net assembly 45 includes a mounting seat 451 sleeved on the connecting shaft 43. A scraping plate 453 in contact with the filter screen 6 is arranged on the mounting seat 451 through a fixing plate 452. The scraping plate 453 penetrates through the fixing plate 452 through a socket 454. A first screw hole 455 is formed on the fixing plate 452, and a second screw hole 456 matching the first screw hole 455 is formed on the scraping plate 453.

[0031] Among them, the scraping plate 453 on the fixing plate 452 is fixed on the connecting shaft 43 through the mounting seat 451. Thus, when the reduction motor 42 drives the stirring rod 44 to rotate to improve the fluidity of the ink, the scraping plate 453 is driven to rotate. The rotating scraping plate 453 scrapes off the impurities and particles filtered and attached on the filter screen 6, thereby keeping the filter screen 6 unobstructed, preventing the filter screen 6 from being blocked, and further improving the filtering efficiency of the ink and ensuring the purity of the ink and the printing quality.

[0032] When the scraping plate 453 needs to be disassembled and replaced, the screw on the first screw hole 455 is unscrewed to make the screw disengage from the second screw hole 456 of the scraping plate 453, and then the scraping plate 453 is pulled out from the socket 454 of the fixing plate 452. When installing a new scraping plate 453, the scraping plate 453 penetrates through the socket 454, and then the screw penetrates through the first screw hole 455 and is screwed into the second screw hole 456.

[0033] It should be noted that, as Figure 2 shown, the side surface of the filter screen 6 facing the inside of the ink storage tank 1 and the side surface of the fixed cylinder 5 facing the inside of the ink storage tank 1 are on the same plane. The fixed cylinder 5 and the filter screen 6 with flush end faces enable the scraping plate 453 to closely fit the surface of the filter screen 6, without additional gaps or protrusions hindering the scraping action. The scraping plate 453 can more effectively scrape off the particles attached to the filter screen 6 during the moving process, ensuring a more thorough cleaning effect.

[0034] Specifically, as Figure 5 and Figure 6 shown, the filter screen 6 is detachably installed on the fixed cylinder 5 through a threaded connection cylinder 51, and a handle 52 is arranged on the threaded connection cylinder 51.

[0035] Among them, when the filter screen 6 is installed and disassembled, the operator holds the threaded connection cylinder 51 with the handle 52, and then the threaded connection cylinder 51 can be disassembled and installed in the fixed cylinder 5 by using the thread, so as to facilitate the maintenance and repair of the filter screen 6 and ensure that the filter screen 6 can effectively filter the ink.

[0036] Specifically, as Figure 1 and Figure 7 shown, the ink feeding assembly 7 includes an ink pump 72 arranged on one side of the ink storage tank 1 through a fixing frame 71. The inlet end of the ink pump 72 is communicated with the fixed cylinder 5 through a connecting hose 73, and a ink feeding pipe 74 is arranged at the outlet end of the ink pump 72.

[0037] Among them, when the ink is transported, the ink pump 72 on the fixing frame 71 is started, the ink in the ink storage tank 1 is pumped out through the connecting hose 73, and then the ink is sent to the ink jetting mechanism of the inkjet printer through the ink feeding pipe 74, so as to realize the ink injection work.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
