[0029] Please refer to Figures 1-6As shown in the figure, the utility model relates to an inkjet mechanism of a printing press, which includes a storage tank 1. The inner wall of the top of the storage tank 1 is fixedly connected with an ink inlet pipe 101. The inner wall of the storage tank 1 is fixedly connected with a conveying pipe 102. The outer wall of one side of the conveying pipe 102 away from the storage tank 1 is fixedly connected with a diaphragm pump 103. The operator starts the diaphragm pump 103. The outer wall of the diaphragm pump 103 is fixedly connected with a fixing frame 104. The outer wall of the fixing frame 104 is fixedly connected with the outer wall of the storage tank 1. The output end of the diaphragm pump 103 is fixedly connected with an inkjet head 105. The diaphragm pump 103 is fixed by the fixing frame 104 to prevent the diaphragm pump 103 from shaking during use. A filtering mechanism 2 is arranged on the outer wall of the storage tank 1. The filtering mechanism 2 includes a controller 201. The outer wall of the controller 201 is fixedly connected with the outer wall of the storage tank 1. The outer wall of the top of the storage tank 1 is fixedly connected with a mounting frame 202. When the first motor 203 is used in the mounting frame 202, the first motor 203 will not shake, so that the first motor 203 operates stably. The inner wall of the mounting frame 202 is fixedly connected with a first motor 203. The operator starts the first motor 203 through the controller 201. The bottom output end of the first motor 203 is fixedly connected with a rotating shaft 204 through a coupling. The outer wall of the rotating shaft 204 is fixedly connected with a cam 205. After the first motor 203 is started, it will drive the rotating shaft 204 to rotate, and then the rotating shaft 204 will drive the cam 205 to rotate, realizing the kinetic energy conduction between parts. A plurality of circular grooves 206 are formed on the inner wall of the top of the storage tank 1. The inner wall of the circular groove 206 is slidably connected with a sliding rod 207. When the sliding rod 207 slides in the circular groove 206, the sliding rod 207 will not shake, so that the sliding rod 207 maintains a linear motion. The outer wall of one side of the sliding rod 207 close to the mounting frame 202 is fixedly connected with a fixing frame 208. The outer wall of the side of the sliding rod 207 away from the fixing frame 208 is fixedly connected with a filter plate 209. When the cam 205 rotates, it will squeeze the fixing frame 208, so that the fixing frame 208 moves. At the same time, the fixing frame 208 will drive the sliding rod 207 to move. When the sliding rod 207 moves, it will drive the filter plate 209 to move. At the same time, the movement of the filter plate 209 filters the ink. A plurality of support plates 210 are fixedly connected to the inner wall of the storage tank 1. The outer wall of the top of the support plate 210 is fixedly connected with a fixing rod 211. When the filter plate 209 slides on the fixing rod 211, the filter plate 209 will maintain a horizontal movement to avoid shaking of the filter plate 209. The outer wall of the fixing rod 211 is slidably connected with the inner wall of the filter plate 209. A spring 212 is sleeved on the outer wall of the fixing rod 211. A stirring mechanism 3 is arranged on the outer wall of the rotating shaft 204. When the spring 212 is squeezed on the fixing rod 211, the spring 212 will not be displaced, so that the spring 212 can be used normally.

[0030] The stirring mechanism 3 includes a crown gear 301. The inner wall of the crown gear 301 is fixedly connected to the outer wall of the rotating shaft 204. A roller 302 is rotatably connected to the inner wall of the storage tank 1. The outer wall of the roller 302 is slidably connected to the inner wall of the filter plate 209. One end of the roller 302 close to the crown gear 301 is fixedly connected to a gear 303 on the outer wall. When the rotating shaft 204 rotates, it will drive the crown gear 301 to rotate, and then the crown gear 301 drives the gear 303 to rotate. At the same time, the roller 302 will rotate following the gear 303, realizing the kinetic energy transfer between parts. The outer wall of the gear 303 meshes with the outer wall of the crown gear 301. The outer wall of the roller 302 is fixedly connected with a plurality of stirring rods 304. When the roller 302 rotates, it will drive the stirring rods 304 to rotate. Then, when the stirring rods 304 rotate, they will stir the ink to prevent pigment precipitation in the ink. The top outer wall of the storage tank 1 is fixedly connected with a fixing plate 305. The inner wall of the fixing plate 305 is rotatably connected to the outer wall of the rotating shaft 204. The rotating shaft 204 is further supported by the fixing plate 305, making the rotating shaft 204 operate more smoothly.

[0031] One end of the rotating shaft 204 away from the first motor 203 is fixedly connected to a pulley 306 on the outer wall. The outer wall of the pulley 306 is drivingly connected to a belt 307. When the rotating shaft 204 rotates, it will drive the pulley 306 to rotate, and then the pulley 306 will drive the belt 307 to move, realizing the kinetic energy conduction process between parts. A rotating rod 308 is rotatably connected to the inner wall of the storage tank 1. One end of the rotating rod 308 close to the pulley 306 is fixedly connected to a belt disc 309 on the outer wall. When the belt 307 moves, it will drive the belt disc 309 to rotate, and then the rotating rod 308 will rotate following the belt disc 309, completing the kinetic energy transfer between parts. The outer wall of the belt disc 309 is drivingly connected to the inner wall of the belt 307. The outer wall of the belt disc 309 is fixedly connected with a plurality of second stirring rods 310. When the rotating rod 308 rotates, it will drive the second stirring rods 310 to rotate. Then, when the second stirring rods 310 rotate, they will further stir the ink.

[0032] A specific application of this embodiment is:

[0033] When the staff needs to use the device, first, the ink is conveyed from the ink inlet pipe 101 to the storage tank 1. Then the ink will fall onto the filter plate 209. At the same time, the first motor 203 is started through the controller 201. After the first motor 203 starts, it will drive the rotating shaft 204 to rotate. Then when the rotating shaft 204 rotates, it will drive the cam 205 to rotate. When the cam 205 rotates, it will squeeze the fixed frame 208, causing the fixed frame 208 to move. When the fixed frame 208 moves, it will drive the sliding rod 207 to slide in the circular groove 206. Then when the sliding rod 207 slides, it will drive the filter plate 209 to move on the fixed rod 211. When the filter plate 209 moves, it will filter the ink to prevent impurity particles from being contained in the ink. Then when the filter plate 209 slides on the fixed rod 211, the filter plate 209 will squeeze the spring 212. When the cam 205 does not contact the fixed frame 208, the spring 212 will squeeze the filter plate 209 to reset the filter plate 209. At the same time, other parts will also be reset. Then the filtered ink will fall below the storage tank 1. At the same time, when the rotating shaft 204 rotates, it will drive the crown gear 301 to rotate. Then the crown gear 301 will drive the gear 303 to rotate. When the gear 303 rotates, it will drive the roller 302 to rotate. At the same time, the stirring rod 304 will rotate along with the roller 302. When the stirring rod 304 rotates, it will stir the ink to make the components in the ink more uniform. At the same time, when the rotating shaft 204 rotates, it will drive the pulley 306 to rotate. Then the pulley 306 drives the belt pulley 309 to rotate through the belt 307. When the belt pulley 309 rotates, it will drive the rotating rod 308 to rotate. Then the second stirring rod 310 will rotate along with the rotating rod 308. When the second stirring rod 310 rotates, it will further stir the ink to avoid the precipitation of pigments in the ink. When using the ink, the diaphragm pump 103 can be started. Then the diaphragm pump 103 pumps out the ink in the storage tank 1 through the delivery pipe 102. Finally, the ink is discharged from the inkjet head 105.
