[0002] The anilox roller is a critical component in printing presses, particularly in flexographic and gravure printing processes. Its primary function is to precisely control the amount of ink or paint transferred and ensure even distribution. However, over time, ink residues can solidify or become difficult to remove within the cells of the roller. Currently, the anilox roller is routinely removed and cleaned during use to ensure optimal printing results.

[0003] Existing patent CN201910473759.4 discloses a flexographic printing anilox roller cleaning device, which specifically discloses that a clamping device for clamping the anilox roller is provided on the frame, and a driving device for driving the anilox roller to rotate around its axis is provided on the clamping device. The frame is also provided with a cleaning device, which includes a T-shaped slider slidably connected to the frame, the T-shaped slider is connected to a cleaning member for cleaning the anilox roller, and the T-shaped slider is also provided with a cleaning device for spraying a cleaning agent on the anilox roller and recovering the cleaning agent. Through the above arrangement, anilox rollers of different models or sizes are clamped by the clamping device, and then the anilox roller is driven to rotate by the driving device. The cleaning member slides along the length direction of the anilox roller following the T-shaped slider, and improves the cleaning efficiency and cleaning effect by spraying the cleaning agent on the anilox roller, and then recovers the cleaning agent and cleaning waste liquid to reduce pollution to the working environment. It has the function of automatically cleaning the anilox roller, is easy to operate, cleans quickly, and improves the efficiency of cleaning the anilox roller. However, the above technical solution cannot completely remove the residue inside the cell, mainly because the cleaning element and the anilox roller always remain in a vertical position during the cleaning process. During the rotation and cleaning of the anilox roller, the sprayed cleaning agent cannot perform multi-angle cleaning on the blind corners of the inner edge of the cell. Secondly, the technical solution cannot be used to understand the real-time cleaning effect of the cell, and it is impossible to determine whether to stop cleaning or continue cleaning, resulting in ineffective operation.

In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0041] Example 1:

[0042] See Figures 1-11, a screen roller cleaning system includes a cleaning box 1, wherein a first chamber A and a second chamber B are provided inside the cleaning box 1, the first chamber A opens upward and is located above the second chamber B, the first chamber A is mainly used for cleaning the screen roller 6, a slide rail 2 is fixedly provided at the bottom of the first chamber A, a first support frame 3 is movably installed on the slide rail 2, a second support frame 4 is fixedly provided at the far end of the first support frame 3, and the bottom of the second support frame 4 is fixedly connected to the bottom of the first chamber A, a speed regulating motor 5 is also fixedly provided at the far end of the second support frame 4, and the speed regulating motor 5 is fixedly connected to the inner wall of the first chamber A, an anilox roller 6 is set between the first support frame 3 and the second support frame 4, wherein the first support frame 3 can move left and right on the slide rail 2, so that it is convenient to pass through the servo The service motor 17 adjusts the distance from the first support frame 3 to the second support frame 4, and can adapt to anilox rollers 6 of different lengths. Tooth plates 7 and T-shaped slides 8 are respectively installed on the inner walls of both sides of the first chamber A. The tooth plates 7 and T-shaped slides 8 are arranged in parallel. Under the action of the driving motor 902, the cleaning component 9 can move left and right along the tooth plate 7, and the T-shaped slide 8 is located on the other side, mainly to ensure that the cleaning component 9 can maintain linear motion, play a positioning and limiting role, and a cleaning component 9 is movably arranged between the tooth plate 7 and the T-shaped slide 8. The cleaning component 9 includes a first cleaning component 90 and a second cleaning component 91. The controller 11 is respectively connected to the speed regulating motor 5, the first cleaning component 90, the second cleaning component 91, the imaging component 10 and the display 12 signals. The first cleaning assembly 90 has two main functions: first, it pulls the second cleaning assembly 91; second, it brushes the anilox roller 6. The first cleaning assembly 90 efficiently removes residue from the cells of the anilox roller 6 after high-pressure cleaning. Furthermore, during the return process, brushing loosens the residual ink, allowing the second cleaning assembly 91 to flush out the residue more effectively. The first cleaning assembly 90 is also connected to the imaging assembly 10. The imaging assembly 10 primarily captures the distribution of residue within the cells. The controller 11 can adjust the angle of the annular water pipe 913 at any time. The annular water pipe 913 can be adjusted at multiple angles, including but not limited to being perpendicular to the anilox roller 6, offset left and right, or offset up and down. This allows the angle of the atomizing nozzle 914 to be changed, thereby cleaning residue from the edges of the cells. The controller 11 and display 12 are also fixedly mounted on the exterior of the cleaning box 1. The display 12 allows for a visual display of the ink distribution within the cells, allowing the controller 11 to control the second cleaning assembly 91 to perform different levels of cleaning.

[0043] See Figure 1-Figure 2The top of the cleaning box 1 is also equipped with a box cover 13 through a hinge. During the cleaning process, the box cover 13 ensures that impurities will not enter the first chamber A and that water will not leak out. Secondly, an observation window 14 and a handle 15 are also provided on the box cover 13. The internal operation status can be observed through the observation window 14, which facilitates the acquisition of the internal status. Support columns 16 are also provided at the four corners of the bottom of the cleaning box 1.

[0044] See Figure 2-Figure 4 , the two ends of the slide rail 2 are also fixedly installed with a servo motor 17 and a base 18, the output end of the servo motor 17 is fixedly installed with a screw 19, the first support frame 3 is sleeved on the screw 19, and the distal end of the screw 19 is installed in conjunction with the base 18. In order to adapt to the different lengths of the anilox roller 6, the screw 19 can be driven to rotate by the servo motor 17. When the screw 19 rotates, the first support frame 3 sleeved with the screw 19 will move along the slide rail 2, and the direction of movement is related to the rotation direction of the screw 19, and the first Arc-shaped limit plates 20 are movably installed on the support frame 3 and the second support frame 4. The arc-shaped limit plates 20 can stabilize the rotating shafts at both ends of the anilox roller 6, so as to prevent the anilox roller 6 from swinging during rotation. The output end of the speed regulating motor 5 is connected to the hollow shaft 21, and the power of the speed regulating motor 5 can be transmitted to the anilox roller 6 through the hollow shaft 21. A number of pre-tightening screws 22 are also movably installed on the hollow shaft 21. The pre-tightening screws 22 can ensure that the power transmission is more stable and can be adjusted to adapt to rotating shafts of different diameters.

[0045] See Figure 5 A water storage tank 23, a recovery tank 24, and a water purifier 25 are also provided inside the second chamber B. The recovery tank 24 is connected to the water outlet 26 via a pipe. The recovery tank 24 is also connected to the water purifier 25 via a pipe. The water purifier 25 is also connected to the water storage tank 23. The water storage tank 23 is connected to an external pipe via a water inlet pipe 27. A water pump 28 is provided inside the water storage tank 23. The water pump 28 is connected to the controller 11 for signal transmission. The output end of the water pump 28 is connected to a bellows 29. The other end of the bellows 29 is connected to the second cleaning assembly 91. The length of the bellows 29 can be adjusted to facilitate movement. The sewage generated during the cleaning process first enters the recovery tank 24 through the water outlet 26, and then passes through the water purifier 25 to filter and purify the sewage. The purified cleaning liquid is collected in the water storage tank 23 and re-sent to the annular water pipe 913 through the water pump 28.

[0046] See Figure 1-Figure 7The first cleaning assembly 90 includes a ring 900, a connecting frame 901, a driving motor 902, a driving gear 903, a connecting arm 904, a T-shaped slider 905 and a cleaning mechanism 906. The cleaning mechanism 906 mainly brushes the surface of the anilox roller 6 during the left and right movement. The ring 900 is sleeved on the anilox roller 6. One end of the ring 900 is respectively fixed with the connecting frame 901 and the connecting arm 904. The connecting arm 904 can mainly ensure that when the driving motor 902 is working, the driving gear 903 can always be kept in mesh with the tooth plate 7, which is equivalent to playing a guiding and limiting role. When the driving motor 902 is working, the ring 900 will move left and right on the anilox roller 6. The moving direction is related to the rotation direction of the drive motor 902. The drive motor 902 is fixedly installed on the connecting frame 901, and the drive motor 902 is also connected to the controller 11 signal. The output end of the drive motor 902 is fixedly installed with a driving gear 903, and the driving gear 903 is engaged with the tooth plate 7. The far end of the connecting arm 904 is fixed with a T-shaped slider 905, and the T-shaped slider 905 is movably mounted in the T-shaped slide groove 8. The ring 900 is also equipped with a cleaning mechanism 906. The other end of the ring 900 is movably mounted with a second cleaning component 91. The second cleaning component 91 is mainly used for spraying cleaning liquid, and the angle can be changed during the spraying and cleaning process.

[0047] The cleaning mechanism 906 includes a nut 9060, an adjusting screw 9061, a spring 9062, a connecting sleeve 9063 and a cleaning plate 9064. Several through circular holes are opened on the ring 900. A nut 9060 is fixedly set on the outside of each through circular hole. The adjusting screw 9061 extends into the through circular hole, and the protruding end is movably connected to the connecting sleeve 9063. The connecting sleeve 9063 is fixedly installed on the cleaning plate 9064. Two springs 9062 are also fixedly connected to each cleaning plate 9064. The other end of each spring 9062 is fixedly connected to the inner wall of the ring 900, and the connecting sleeve 9063 is located in the middle of the two springs 9062. After the anilox roller 6 is placed between the first support frame 3 and the second support frame 4, the cleaning mechanism 906 needs to be manually adjusted according to the diameter of the anilox roller 6. First, by twisting the adjusting screw 9061, the bottom of the adjusting screw 9061 drives the cleaning plate 9064 to move downward. The cleaning plate 9064 is an arc-shaped structure. The arc-shaped cleaning plate 9064 can fit with the surface of the anilox roller 6, so that there is a certain pressure between the brush 30 and the anilox roller 6, so that the brush 30 will extend into the mesh hole. The adjusting screw 9061 mainly adjusts the spacing, which is convenient for adjusting the distance according to the wear of the brush 30 to prevent the brush 30 from not contacting or the contact pressure is insufficient, resulting in the inability to brush out ink residues, etc. The number is not less than four, and a brush 30 is also provided on the side of the cleaning plate 9064 facing the anilox roller.

[0048] The second cleaning assembly 91 includes a universal ball head 910, an electric cylinder 911, a telescopic rod 912, a circular water pipe 913 and an atomizing nozzle 914. Three universal ball heads 910 are fixedly arranged on the circumference of the end face of the circular ring 900. The end of each universal ball head 910 is connected to the bottom of the electric cylinder 911. Each electric cylinder 911 is respectively connected to the controller 11 by signal. A telescopic rod 912 is movably arranged at the front end of the electric cylinder 911. Each electric cylinder 911 can control the length of the telescopic rod 912 at the end through the controller 11, that is, the length is adjusted by controlling the working stroke of the electric cylinder 911. The three electric cylinders 911 are distributed at equal intervals, and the bottom of each electric cylinder 911 is movably connected to the circular ring 900 through the universal ball head 910. The telescopic rod 912 at the top is also movably hinged to the circular water pipe 913. Several atomizing nozzles 914 are fixedly installed on the inner circular wall of the circular water pipe 913. The circular water pipe 913 is also connected to the bellows 29.

[0049] When the residue displayed on the display 12 is concentrated in the middle of the cell, the pre-processing unit recognizes it as F K2 , then the controller 11 controls the three electric cylinders 911 to be in the same stroke, and the three electric cylinders 911 are distributed circumferentially and in different spaces, so that the telescopic rod 912 at the top of each electric cylinder 911 maintains the same length, so that the annular water pipe 913 can be perpendicular to the anilox roller 6, as shown Figure 8 As shown, the atomizing nozzle 914 vertically flushes the cells. When the residues displayed on the display 12 are concentrated at the edge of the cells, the pre-processing unit recognizes them as F K1 , it is necessary to control the stroke of different electric cylinders 911 through the controller 11 so that the length of each telescopic rod 912 is no longer the same, so that the circular water pipe 913 is offset, such as Figure 9 and Figure 10 As shown, the atomizing nozzle 914 can clean the residues at all angles inside the mesh cells, especially at the edges of dead corners. During this process, the angle of the circular water pipe 913 should not be too large to avoid contact friction between the atomizing nozzle 914 and the surface of the anilox roller 6, which can ensure more thorough cleaning.

[0050] The imaging assembly 10 includes a hollow square tube 100, a telescopic square tube 101, a fastening screw 102, a vertical pole 103, a lifting seat 104, a movable arm 105, a sleeve 106, a camera 107 and a transmitter 108. One end of the hollow square tube 100 is fixed to one end of the connecting frame 901, and the upper part of the hollow square tube 100 is equipped with a fastening screw 102. The fastening screw 102 can control the length of the telescopic square tube 101 extending out of the hollow square tube 100, thereby avoiding the influence of the cleaning liquid on the camera 107 during the cleaning process, and the lifting seat 104 on the vertical pole 103 can be adjusted in height, thereby conveniently adjusting the vertical distance between the camera 107 and the anilox roller 6, which is convenient for To adjust the clarity, a telescopic square tube 101 is installed in the hollow square tube 100. A vertical pole 103 is installed at the far end of the telescopic square tube 101. A lifting seat 104 is installed on the vertical pole 103. The lifting seat 104 is fixedly connected to a movable arm 105. A sleeve 106 is vertically fixedly installed on the movable arm 105. A camera 107 is fixedly installed at the bottom of the sleeve 106. The image information collected by the camera 107 is directly transmitted to the controller 11 through the transmitter 108, and then output to the display 12 after the controller 11. A transmitter 108 is fixedly installed on the top of the sleeve 106. The transmitter 108 is connected to the controller 11 by signal. The real-time effect of the display 12 is shown in the figure below. Figure 11 As shown in the figure, it can be seen that shadows exist at the blind corners of the edges of some cells. This shows that the circular water pipe 913 needs to be controlled to deflect in order to completely remove the residues at the edges of the cells.

[0051] The present invention also provides a cleaning method based on the anilox roller cleaning system, comprising the following steps:

[0052] S1: When the system is in use, the cover 13 is opened, one end of the rotating shaft of the anilox roller 6 is placed on the second support frame 4, and the rotating shaft of the anilox roller 6 is pushed into the hollow shaft 21. The anilox roller 6 is fixed to the hollow shaft 21 by the pre-tightening screw 22. Then, the drive motor 902 is operated by the controller 11, so that the second cleaning assembly 91 and the first cleaning assembly 90 are sequentially mounted on the anilox roller 6. During the reciprocating movement of the first cleaning assembly 90, the second cleaning assembly 91 and the imaging assembly 10 are driven to move together.

[0053] S2: The controller 11 controls the servo motor 17 to operate, causing the first support frame 3 to move axially to the right along the lead screw 19 until the first support frame 3 is located below the right end rotation shaft of the anilox roller 6. Then, the arc-shaped limit plates 20 on the first support frame 3 and the second support frame 4 are manually closed, so that the anilox roller 6 is movably mounted on the first support frame 3 and the second support frame 4. Then, the position of each cleaning plate 9064 is adjusted by adjusting the screw 9061 so that the brush 30 contacts the surface of the anilox roller 6. Finally, the imaging assembly 10 is adjusted to the optimal position, so that the equipment can start the cleaning operation.

[0054] S3: Cleaning operation. In this process, the controller 11 controls the drive motor 902 to move left or right along the tooth plate 7, so that the cleaning component 9 as a whole moves left or right on the anilox roller 6. At this time, the speed regulating motor 5 and the water pump 28 also start working. The speed regulating motor 5 causes the anilox roller 6 to start rotating, and the water pump 28 inputs the cleaning liquid into the annular water pipe 913 through the bellows 29. In this process, the annular water pipe 913 continuously changes its position and angle through the adjustment mechanism. The adjustment mechanism is mainly based on the image information obtained by the controller 11. According to the distribution of residues inside the cells, the cells of the anilox roller 6 can be cleaned in a targeted manner. After cleaning, it is brushed with a brush 30 until the cleaning is completely completed.

[0055] The specific steps of the regulation mechanism include:

[0056] S30: Image acquisition: During the cleaning process, the image Q of the anilox roller 6 is acquired in real time through the camera 107. S , and fed back to the controller 11 through the transmitter 108. At the same time, the controller 11 converts the image Q S The ink residue inside the cells can be observed by visually displaying it on the display 12;

[0057] S31: Image processing, the controller 11 processes the image Q S , the image Q is transformed into S Remove noise and then split into different sub-images Q ZS , then each sub-image Q ZS Mark different coordinate areas A K , and at the same time obtain each coordinate area A K The shadow shape feature F K , shadow morphological feature F K Including F K1 and F K2 , where F K1 Indicates that there is a shadow at the edge of the cell, F K2 Indicates that there is a shadow in the middle of the cell;

[0058] S32: Adjustment mechanism, in the next cleaning process, when the circular water pipe 913 reaches the designated sub-image Q ZS When the corresponding anilox roller 6 position is selected, firstly according to the different coordinate areas A K , while keeping the annular water pipe 913 perpendicular to the anilox roller 6, the atomizing nozzle 914 changes the spray pressure and spray time at any time. In the actual process, each coordinate area A K The specific injection pressure and time depend on the shadow morphology characteristics F K1 and F K2 When identifying the size of FK2 When the residue fills the entire cell, a greater cleaning intensity is required. K1 When the residue is concentrated on the edge, it is necessary to carry out local cleaning according to the shadow morphological characteristics F K1 and F K2 The controller 11 can control each electric cylinder 911 at any time, so that the travel of the telescopic rod 912 of each electric cylinder 911 changes, thereby causing the circular water pipe 913 to change at different angles, thereby achieving efficient cleaning.

[0059] The following table identifies F K2 When , the system parameters are compared with the experimental data.

[0060]

[0061] By comparing the data in the above table, it can be seen that when the spray pressure of the atomizing nozzle 914 is 100 Bar and the time is 15 ms, its coverage and residue removal rate are better than those under other parameters.

[0062] The following table identifies F K1 When , the system parameters are compared with the experimental data.

[0063]

[0064] Comparing the data in the table above, it can be seen that when shadows exist at the edge, the atomizing nozzle 914 achieves a better debris removal rate and a lower center false positive rate when the spray pressure is 70 bar and the spray time is 10 ms compared to other parameters. The center false positive rate mainly refers to the number of false positives on the cell center caused by the atomizing nozzle 914 during the process of changing the angle of the circular water pipe 913. A higher number of false positives will cause changes in the cell depth, which can seriously affect print quality.
