[0002] Flexographic printing is an important printing method, which can achieve high-resolution image printing. Flexographic plate-making machines play a very important role in flexographic printing and are widely used in many fields such as electronic products, medical devices, and packaging printing. High-compatible flexographic plate-making machines are flexographic plate-making devices with wide adaptability and compatibility, and can flexibly handle diverse printing tasks.

[0030] Furthermore, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the transmission assembly 8 includes a servo motor 81. The servo motor 81 is fixed to one side wall of the frame 2. One end of the anilox roller 4 is coaxially fixed to one end of the output shaft of the servo motor 81. Belt pulleys 82 are fixed between the anilox roller 4 and the plate cylinder 5. A belt 83 is sleeved on the outer surfaces of the two belt pulleys 82. Straight gears 84 are arranged between the plate cylinder 5 and the impression cylinder 6, and the two straight gears 84 mesh with each other; there are two bearing plates 85. The two bearing plates 85 are symmetrically distributed and fixed to one side wall of the frame 2. One side of the bearing plate 85 is fixed to the top side wall of the workbench 1. Slots 86 are opened on one side of the two bearing plates 85. A bearing roller 87 is rotatably connected inside the slot 86. A sheet 88 is wound on the outer surface of the bearing roller 87. The sheet 88 is stretched and pulled between the plate cylinder 5 and the impression cylinder 6. Through the setting of the transmission assembly 8, it is ensured that the anilox roller 4, the plate cylinder 5 and the impression cylinder 6 operate in a relatively stable and smooth state, thus having a good guarantee for the qualification rate of the plate-making products, and having the advantages of strong structural reliability and simple operation, and having a good market promotion prospect.

[0031] Further, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, it is worth specifically stating that a moisturizing component 9 adapted to the anilox roller 4 is provided on one side of the frame 2. The moisturizing component 9 includes a mounting frame 91, and the mounting frame 91 is fixed to the top side wall of the workbench 1. A movable plate 92 is slidably connected to one side wall of the mounting frame 91. A plurality of spray pipes 93 are fixed to one side wall of the movable plate 92 at equal intervals.

A water tank 98 is fixed to one side wall of the workbench 1. A water supply pipe 910 is fixed between the input end of the water pump 96 and the water tank 98; two bearing seats 911, and the two bearing seats 911 are symmetrically distributed and fixed to one side wall of the mounting frame 91. A threaded rod 912 is rotatably connected between the two bearing seats 911. The external thread of the threaded rod 912 is threadedly connected to the movable plate 92. A driving motor 99 is fixed to one side wall of the workbench 1. One end of the output shaft of the driving motor 99 is coaxially fixed to one end of the threaded rod 912. Through the setting of the moisturizing component 9, the water spray amount of the atomizing nozzle 94 can be adjusted according to specific actual needs, so as to meet the needs of different plate-making operations. Moreover, the distance between the atomizing nozzle 94 and the anilox roller 4 can be flexibly adjusted, which is more applicable to different plate-making processing requirements, has good practicability, can save the working link of the staff continuously wiping the plate in a high-temperature weather environment, can greatly reduce the labor intensity of the staff, not only can reduce the loss of finished products, but also can greatly improve the qualification rate of finished products.

[0032] The working process of this solution is as follows: When flexible plate-making of the plate material is required, first place the carrier roller 87 in the card slot 86, stretch the plate material to be located between the plate cylinder 5 and the impression cylinder 6, and through the drive of the servo motor 81, the anilox roller 4 rotates synchronously, so that the anilox roller 4 contacts the ink in the ink cartridge 3, thereby ensuring that a sufficient amount of ink is adsorbed on the surface of the anilox roller 4. The excess ink on the surface of the anilox roller 4 is wiped by the doctor blade 7, so that the excess ink flows into the ink cartridge 3 for storage. By the transmission of the belt pulley 82 and the belt 83, the plate cylinder 5 rotates synchronously, and by the meshing transmission of the two spur gears 84, the plate cylinder 5 and the impression cylinder 6 rotate in opposite directions, so as to complete the flexible plate-making processing of the plate material 88. When moisturizing is required at the anilox roller 4, through the drive of the water pump 96, the water source in the water tank 98 is pumped and pressurized by the water supply pipe 910, and the pressurized water source is conveyed into the communicating pipe 95 by the flexible hose 97, and the communicating pipe 95 conveys the water source into the spray pipes 93 in turn, so that the atomizing nozzle 94 generates water mist to humidify and moisturize the anilox roller 4.

[0033] According to the above working process, it can be seen that through the setting of the moisturizing component 9, the water spray amount of the atomizing nozzle 94 can be adjusted according to specific actual needs, so as to meet the different plate-making work requirements. Moreover, the distance between the atomizing nozzle 94 and the anilox roller 4 can be flexibly adjusted, which is more suitable for different plate-making processing work requirements, has good practicability, can save the working link of the staff continuously wiping the plate in a high-temperature weather environment, can greatly reduce the labor intensity of the staff, not only can reduce the loss of finished products, but also can greatly improve the qualification rate of finished products. And through the setting of the water collecting box 10, the situation that the atomizing nozzle 94 dripping water affects the device can be effectively solved, the situation that the device rusts due to the dripping water at the atomizing nozzle 94 can be effectively prevented, and the situation that the proportion of the ink at the anilox roller 4 is out of balance due to the dripping water of the atomizing nozzle 94 can be avoided. The situation that the color of the plate-making product is uneven due to the different depths of the ink can be avoided, so as to greatly guarantee the qualification rate of the plate-making product, and the service life of the device is further improved.

[0034] Further, as Figure 1 , Figure 2 and Figure 3 shown, it is worth specifically explaining that a water collecting box 10 is fixed on one side wall of the movable plate 92. The water collecting box 10 is located directly below a plurality of atomizing nozzles 94. Through the setting of the water collecting box 10, the situation that the atomizing nozzle 94 dripping water affects the device can be effectively solved, the situation that the device rusts due to the dripping water at the atomizing nozzle 94 can be effectively prevented, and the situation that the proportion of the ink at the anilox roller 4 is out of balance due to the dripping water of the atomizing nozzle 94 can be avoided. The situation that the color of the plate-making product is uneven due to the different depths of the ink can be avoided, so as to greatly guarantee the qualification rate of the plate-making product, and the service life of the device is further improved.

The water inlet pipe 13 is communicated with the inside of the ink cartridge 3. One end of the water inlet pipe 13 is fixedly connected with a water inlet hopper 14. Through the setting of the water inlet hopper 14 and the water inlet pipe 13, it is convenient for the staff to add ink to the ink cartridge 3 in time, so as to prevent the situation of plate breakage caused by insufficient ink storage in the ink cartridge 3, thereby further improving the qualification rate of the plate-making product. And in cooperation with the setting of the water outlet pipe 11 and the faucet 12, it is beneficial for the staff to discharge the ink in the ink cartridge 3, and prevent the situation that the ink in the ink cartridge 3 deteriorates due to the long time and affects the quality of the finished product.

[0036] Further, asFigure 3 As shown, it is worth specifically explaining that a mounting seat 15 is fixed on one side wall of the workbench 1, and the water outlet pipe 11 is fixed inside the mounting seat 15.
