A vibrator 205 is connected to the lower end of the bracket 204. The vibrator 205 and the bracket 204 are connected. A stirring blade 206 is installed inside the second ink cartridge 201. A first bevel gear 207 is detachably installed at the lower end of the stirring blade 206. A servo motor 208 is installed at the lower end of the second ink cartridge 201. A second bevel gear 209 is fixedly connected to the output end of the servo motor 208. The first bevel gear 207 and the second bevel gear 209 are meshed together.

[0026] In one specific embodiment, the ink supply component 100, in conjunction with the stirring and sieving component 200, not only performs vibration sieving and stirring operations on the ink blocks, thereby improving the processing quality of the ink blocks, but also facilitates stable delivery of printing ink through the cooperation of the above structures, thus improving the ink supply smoothness of the printer. In use, the ink blocks are first placed on the upper end of the screen 203, and then the vibrator 205 is started to vibrate the screen 203, breaking the ink blocks into the second ink cartridge 201. The presence of the spring 222 increases the vibration amplitude of the screen 203, thereby improving the sieving efficiency of the ink blocks. At this time, the servo motor 2 is activated. 08 rotates with the second bevel gear 209, which in turn rotates the first bevel gear 207 and its upper stirring blade 206 to stir the ink block, thus improving the processing quality of the printing ink. When the printer is in use, the ink supply pump draws the printing ink from the second ink cartridge 201 and delivers it into several first ink tubes 1051. The ink then enters several ink sacs 102 through the first ink tubes 1051. At this time, the printing ink passes through several second ink tubes 1052 and enters the print head 104, thus enabling printing. The above structures work together to facilitate stable ink supply, thereby improving the smoothness of printer operation.

[0029] Please see Figure 2 A support plate 111 is fixedly connected to the lower end of the first ink cartridge 101.

[0030] In one specific embodiment, the support plate 111 can improve the installation stability of the first ink cartridge 101, thereby improving the safety of use.

[0031] Please see Figures 3-5 The inner wall of the second ink cartridge 201 has two guide grooves 211 on both sides, and the screen 203 has two guide blocks 212 fixedly connected to both sides. The two guide blocks 212 are slidably connected inside the guide grooves 211.

[0032] In one specific embodiment, when the screen 203 vibrates, the guide block 212 moves up and down along the guide groove 211, thereby improving the vibration stability of the screen 203 and thus improving the screening effect on the ink block.

[0033] Please see Figures 3-5 A positioning rod 221 is fixedly connected inside the guide groove 211. A spring 222 is sleeved on the side surface of the positioning rod 221. The positioning rod 221 is inserted into the inside of the guide block 212.

[0034] In one specific embodiment, the positioning rod 221 is inserted into the guide block 212 to guide the screen 203, and the presence of the spring 222 can increase the vibration amplitude of the screen 203 and improve the screening quality of the ink block.

[0035] Please see Figures 3-5 The lower end of the stirring blade 206 is provided with several slots 231, and the upper end of the first bevel gear 207 is fixedly connected with several blocks 232, all of which are engaged inside the slots 231.

[0036] In one specific embodiment, the locking block 232 is engaged inside the locking slot 231, thereby improving the ease of disassembly and replacement of the first bevel gear 207 and the stirring blade 206.

[0037] Please see Figures 3-5 The lower end of the second ink cartridge 201 is fixedly connected to several support legs 241, and the lower ends of the several support legs 241 are connected to a stabilizing plate 242.

[0038] In one specific embodiment, the support leg 241, together with the stabilizing plate 242, can significantly improve the vibration stability of the second ink cartridge 201, thereby improving the safety of using the second ink cartridge 201.

[0039] Working principle: In use, the ink block is first placed on the upper end of the screen 203 and the vibrator 205 is started to vibrate the screen 203, which breaks the ink block into the second ink cartridge 201. Then, the servo motor 208 is started to rotate the second bevel gear 209, which in turn rotates the first bevel gear 207 and its upper stirring blade 206 to stir the ink block, thereby improving the processing quality of the printing ink. When the printer is in use, the ink is drawn from the second ink cartridge 201 by the ink pump and delivered into several first ink tubes 1051. The ink then enters several ink sacs 102 through the first ink tubes 1051. At this time, the printing ink passes through several second ink tubes 1052 and enters the print head 104, thus enabling the printing operation. The above structure works together to facilitate stable ink supply, thereby improving the smoothness and convenience of printer operation.
