[0029] Example 1, as Figure 1-5 As shown, a blowing device of a flexible printing machine 1 with an air supply function includes a flexible printing machine 1 and a pressure roller 7. A bracket 4 is symmetrically arranged on one side of the flexible printing machine 1. An electric telescopic rod 5 is fixedly connected to one side of the inner wall of the bracket 4. The output end of the electric telescopic rod 5 is fixedly connected to a rectangular slider 6. The rectangular slider 6 is slidably connected to the inner wall of the bracket 4. The two ends of the pressure roller 7 are respectively rotatably connected to one side of the two rectangular sliders 6. A nozzle 8 is passed through and connected between one side of the two device brackets 4. A fan 9 is fixedly connected to one side of the nozzle 8. One side of the fan 9 is fixedly connected to one side of the bracket 4. A cleaning device 2 is symmetrically arranged between the two rectangular sliders 6. The cleaning device 2 can clean the dust and impurities attached to the pressure roller 7. The effect achieved by the above components is as follows: when the blowing device is installed on the flexible printing machine 1 for use, the electric telescopic rod 5 on the bracket 4 is first started to drive the rectangular slider 6 to slide downward in the inner wall of the bracket 4, driving the pressure roller 7 to move downward, and the surface is close to the conveyor belt on the flexible printing machine 1. When the printed paper is placed on the conveyor belt of the flexible printing machine 1 for transmission, after it is transmitted to a certain position, the fan 9 is started to suck the external air into the nozzle 8 and spray it out, blowing it towards the moving paper. The air pressure flattens it and makes it close to the conveyor belt. Then, when it is transported to the pressure roller 7, the pressure roller 7 rotates under the drive of the transmission belt, flattening the printed paper between the two. While the pressure roller 7 rotates, the cleaning device 2 close to the outer surface can clean the dust and impurities attached to its surface to avoid dirtying the printed paper during flattening, affecting the effect and quality of later printing.

[0030] Reference Figure 1-5As shown, this embodiment discloses a cleaning device 2 including a brush 22, each of which is fixedly connected to a connecting frame 21 at both ends. One side of the connecting frame 21 is fixedly connected to one side of a rectangular slider 6. A scraper 23 is fixedly connected to the outer surface of the brush 22, and one end of the scraper 23 is inclined and closely attached to the outer surface of the pressure roller 7. During the rotation of the pressure roller 7, when the surface of the pressure roller 7 contacts the scraper 23 and one side of the brush 22, the scraper 23 can remove dust and impurities that are relatively firmly attached to the surface. The brush 22 can also provide a fine cleaning of the surface, making it less likely to adhere to dust, thereby preventing the printed paper from being contaminated during flattening and affecting the quality of subsequent printing. A collection mechanism 27 is disposed between the two connecting frames 21. The collection mechanism 27 includes a collection box 272. A slot 271 is defined on one side of the connecting frame 21. The slot 271 has an L-shaped longitudinal cross-section. A block 273 is fixedly connected to each side of the collection box 272, and one end of the block 273 is inserted into the inner wall of the slot 271. Before using the brush 22 to clean the pressure roller 7, first manually insert the clamping blocks 273 on both ends of the collection box 272 into the two clamping slots 271 to a certain position, and then allow the clamping blocks 273 to be clamped in place by gravity on the inner wall of one end of the clamping slot 271, so that the collection box 272 is directly below the brush 22. The dust and impurities brushed off are cleaned to prevent the cleaned dust and impurities from falling on the conveyor belt and printed paper on the flexible printing machine 1, thereby improving the cleaning effect. A handle block 274 is fixedly connected to one side of the collection box 272. The cross-section of the handle block 274 is U-shaped. By providing the handle block 274, the contact area of ​​one side of the collection box 272 can be increased, making it easier to manually grasp one side of the collection box for installation or removal.

[0031] Reference Figure 1-5 As shown, this embodiment discloses that the outer surfaces of both ends of the brush 22 are symmetrically fixedly connected to reinforcement rods 24, and one end of the reinforcement rod 24 is fixedly connected to one side of the connecting frame 21. By providing the reinforcement rod 24, the connection area between the brush 22 and the connecting frame 21 can be increased, making the connection more secure and less prone to breakage and damage. The outer surface of the brush 22 is symmetrically fixedly connected to connecting rods 25, and a sponge roller 26 is rotatably connected between one side of the two connecting rods 25. By providing the connecting rod 25 and the sponge roller 26, the brush 22 can be attached to wipe off the fine fluff adhering to the pressure roller 7, making it clean more thoroughly.

[0032] Reference Figure 1-5As shown, this embodiment discloses a detachable device 3 including two bolts 34. A mounting slot 31 is defined on both sides of the rectangular slider 6. The inner walls of the mounting slots 31 are symmetrically defined with threaded holes 32. A screw block 33 is fixedly connected to one side of the connecting frame 21. One end of the screw block 33 is inserted into the inner wall of the mounting slot 31, and one end of the bolt 34 is screwed into the inner walls of the threaded holes 32 and the screw block 33. To replace the brush 22, the bolt 34 can be manually unscrewed from the threaded holes 32 and the inner walls of the screw block 33. The connecting frame 21 can then be pulled toward one end, removing the screw block 33 from the inner wall of the mounting slot 31. This allows the brush 22 to be removed from one side of the rectangular slider 6, facilitating its replacement. One end of the bolt 34 has a screw groove 35, which has a hexagonal longitudinal cross-section. By providing the screwing groove 35 , when it is inconvenient to manually screw the bolt 34 , a screwing tool of corresponding shape can be inserted into the screwing groove 35 , and the bolt 34 can be screwed, making it easier to install.

[0033] Working principle: when installing the blowing device on the flexible printing machine 1 for use, first manually clamp the blocks 273 on both ends of the collection box 272 into the two card slots 271 to a certain position, and then make it clamped in the inner wall of one end of the card slot 271 under the action of gravity so that the collection box 272 is located directly below the brush 22, and then start the electric telescopic rod 5 on the bracket 4 to drive the rectangular slider 6 to slide downward in the inner wall of the bracket 4, driving the pressure roller 7 to move downward, and the surface is close to the conveyor belt on the flexible printing machine 1. When the printed paper is placed on the conveyor belt of the flexible printing machine 1 for transportation, after it is transported to a certain position, start the fan 9 to suck the external air into the nozzle 8 and spray it out, blowing it towards the moving paper, and the air pressure makes it flat and close to the conveyor belt. The scraper 23 and the brush 22 are used to clean the dust and impurities firmly attached to the surface of the press roller 7. The brush 22 and the sponge roller 26 can clean the surface of the press roller 7 to prevent dust from adhering to the surface of the press roller 7. This will prevent the printed paper from being stained during flattening and affect the effect and quality of subsequent printing. The cleaned dust and impurities will fall into the collection box 272 below for collection, which is convenient for unified treatment later. At the same time, it can prevent the cleaned dust and impurities from falling on the conveyor belt and printed paper on the flexible printing machine 1, thereby improving the cleaning effect.

[0034] When the brush 22 needs to be replaced, the bolt 34 can be manually screwed out from the threaded hole 32 and the inner wall of the screw hole block 33, and then the connecting frame 21 can be pulled toward one end so that the screw hole block 33 on one end is pulled out from the inner wall of the mounting groove 31, so that the brush 22 can be removed from one side of the rectangular slider 6 for easy replacement.
