[0002] Anilox rollers, as key components in flexographic printing and coating production lines, are highly susceptible to clogging by ink, glue, and paint residues. Prolonged clogging leads to decreased print quality, uneven ink distribution, and severely impacts production efficiency and product quality.

[0003] Traditional anilox roller cleaning methods mainly include: manual scrubbing, which is inefficient, incomplete, and prone to damaging the roller surface; high-pressure water cleaning, but the cleaning pressure is difficult to control, easily causing damage and deformation to the anilox roller cells, affecting its service life; and chemical cleaning, which requires large amounts of chemical reagents, is environmentally unfriendly, and poses a risk of operator exposure to toxic and harmful substances. Additionally, there is ordinary ultrasonic cleaning, but existing ultrasonic cleaning equipment is mostly general-purpose, and its structural design is not optimized for the characteristics of anilox rollers, resulting in unstable cleaning effects and difficulty in removing deep-seated blockages in the cells. Furthermore, equipment operation usually still relies on manual adjustments, leading to low efficiency, high labor intensity, and a lack of necessary safety precautions during the cleaning process, posing safety hazards.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] As mentioned in the background technology, existing anilox roller cleaning technologies generally suffer from defects such as low cleaning efficiency, unstable cleaning effect, easy damage to anilox rollers, cumbersome operation and poor safety, which cannot meet the needs of modern industrial production for efficient, thorough, safe and automated cleaning.

[0030] Regarding the above issues, please refer to the appendix. Figure 1 To be continued Figure 8The present invention provides an anilox roller cleaning device, the overall structure of which is designed to achieve efficient and automated cleaning of anilox roller 600.

[0031] In a further embodiment, the cleaning device includes a support frame 100, which serves as the supporting framework for the entire device. The support frame 100 may be equipped with at least two sets of liquid storage tanks 300 and at least two sets of lifting cleaning mechanisms 500, as needed, to achieve parallel cleaning of multiple anilox rollers and significantly improve work efficiency.

[0032] In a further embodiment, the lifting and cleaning mechanism 500 is mounted on the bracket 100. The lifting and cleaning mechanism 500 includes a guide rod 54 mounted on the bracket 100 along a third direction Z, for example, a vertical direction, and a cleaning assembly 52 slidably mounted on the guide rod 54 along the third direction Z. The cleaning assembly 52 is the core unit for cleaning the anilox roller 600, and it includes a cleaning tank 522 for placing and cleaning the anilox roller 600. The cleaning tank 522 is typically a rectangular or circular tank, and its interior is used to hold cleaning fluid. An extension plate 521 is provided on the outer side of the cleaning tank 522, which facilitates the installation of subsequent components. To enable the cleaning assembly 52 to slide smoothly on the guide rod 54, a guide block 55 is also mounted on the guide rod 54, which cooperates with the extension plate 521 of the cleaning assembly 52. Specifically, the guide block 55 is provided with a locking block 56 on one side near the extension plate 521. The locking block 56 is located at the lower part of the extension plate 521, forming a sliding locking structure to ensure the stability and positioning accuracy of the cleaning component 52 during the lifting process.

[0033] In a further embodiment, a drive assembly 51 is also installed on the bracket 100 to drive the cleaning assembly 52 to reciprocate along a third direction Z, thereby raising and lowering the cleaning tank 522 so that the anilox roller 600 is immersed in or detached from the cleaning liquid. The specific structure of the drive assembly 51 includes: a first motor 511 mounted on the bracket 100 as the power source for raising and lowering; a first sprocket 512 connected to the first motor 511; and the first sprocket 512 mounted on a rotating shaft 514 arranged along a first direction X, for example, a horizontal direction. The rotating shaft 514 is mounted on the bracket 100 via a shaft seat to ensure smooth rotation. To achieve synchronous drive of both sides of the cleaning assembly 52, a second sprocket 513 is provided at one end of the rotating shaft 514 along the third direction Z. The second sprocket 513 is connected to one side of the extension plate 521 via a chain. A third sprocket 515 is provided at the other end of the rotating shaft 514 along the second direction Y, for example, a horizontal direction perpendicular to the first direction X. The third sprocket 515 is connected to the other side of the extension plate 521 via a fourth sprocket 516 provided along the third direction Z and a chain. This multi-sprocket transmission method ensures that the cleaning assembly 52 remains horizontally stable during lifting and lowering, avoiding tilting.

[0034] In a further embodiment, a rotating rod 526 is provided inside the cleaning tank 522 to enable the rotation of the anilox roller 600. The cleaning tank 522 also has positioning components 53 along a first direction X, such as the anilox roller axial direction, and on both sides of the anilox roller 600 for precise positioning of the anilox roller 600. When the anilox roller 600 is precisely positioned by the positioning components 53 and is located within the cleaning tank 522, the rotating rod 526 contacts the side of the anilox roller 600. When the rotating rod 526 rotates, through friction or mechanical engagement, the anilox roller 600 rotates synchronously with the rotating rod 526, thereby achieving uniform force distribution on the anilox roller in the cleaning liquid.

[0035] In a further embodiment, the positioning component 53 is specifically mounted on both ends of the cleaning tank 522 via a base 57. The positioning component 53 includes a slide rail 532 mounted on the base 57 along a first direction X and a slider 531 mounted on the slide rail 532. A fixing plate 534 is mounted on the upper part of the slider 531. To achieve automated and precise positioning, a cylinder 533 is provided between the fixing plate 534 and the base 57. The extension and retraction of the cylinder 533 can drive the fixing plate 534 to move along the slide rail 532. A positioning rod 535 is provided on the side of the fixing plate 534 facing the anilox roller 600 along a third direction Z. When the anilox roller 600 is placed into the cleaning tank 522, the cylinder 533 drives the fixing plate 534 to move the positioning rod 535, precisely clamping and positioning the anilox roller 600.

[0036] To drive the rotating rod 526 to rotate, a second motor 524 is provided on the upper part of the outer plate 521 of the cleaning tank 522. The second motor 524 is connected to the rotating rod 526 in the cleaning tank 522 through the conveyor belt 525, and drives the rotating rod 526 to rotate along the axial direction of the anilox roller 600.

[0037] In a further embodiment, the cleaning device also includes a storage tank 300 for storing and processing the cleaning fluid. A heating rod 32 is installed in the storage tank 300 to heat the cleaning fluid to the optimal cleaning temperature, improving cleaning efficiency. Simultaneously, a spray storage tank 33 is also installed in the storage tank 300, which may be used for spray rinsing after cleaning or as a buffer for cleaning fluid circulation. Several filter screens 31 are installed between the heating rod 32 and the spray storage tank 33 for preliminary filtration of the cleaning fluid, removing larger particles of impurities. The storage tank 300 and the cleaning tank 522 are connected via a vertical pump 700 and pipelines. The vertical pump 700 is responsible for pumping the cleaning fluid from the storage tank 300 to the cleaning tank 522 or for circulation. A filter 800 is also installed between the vertical pump 700 and the cleaning tank 522 for finer filtration of impurities, further ensuring the cleanliness of the cleaning fluid.

[0038] In a further embodiment, to achieve the ultrasonic cleaning function, the device further includes an ultrasonic generator 400. The ultrasonic generator 400 is electrically connected to a vibrating plate 523 disposed inside the cleaning tank 522, and the vibrating plate 523 transmits ultrasonic energy to the cleaning fluid. To ensure uniform distribution of ultrasonic energy and cleaning effect, at least two sets of vibrating plates 523 are provided, distributed at different positions in the cleaning tank 522.

[0039] In a further embodiment, the automated operation of the entire cleaning device is centrally controlled by an electrical control box 200. The electrical control box 200 is electrically connected to key functional components such as the ultrasonic generator 400, the heating rod 32, the first motor 511 and the second motor 524 of the lifting cleaning mechanism 500, and the vertical pump 700. The electrical control box 200 typically contains electrical components such as a PLC (Programmable Logic Controller), a frequency converter, and relays, enabling precise control of the start, stop, speed, and stroke of each component based on preset programs and sensor feedback, thus achieving automation and intelligence of the entire cleaning process.

[0040] This anilox roller cleaning device is automated through the electrical control box 200. When the anilox roller 600 is loaded by a forklift, the drive assembly 51 controls the cleaning tank 522 in the lifting cleaning mechanism 500 to descend, avoiding the forklift. After the anilox roller 600 is in position, the positioning assembly 53 extends the positioning rod 535 to precisely lock it in place. After positioning, the drive assembly 51 controls the cleaning tank 522 in the lifting cleaning mechanism 500 to rise. During cleaning, the lower part of the anilox roller 600 is immersed in the cleaning solution. Simultaneously, the ultrasonic generator 400 is activated, and the second motor 524 drives the rotating rod 526 to rotate the anilox roller 600 in the cleaning solution, ensuring that the surface of the anilox roller 600 receives comprehensive and uniform ultrasonic cleaning. After cleaning, the cleaning tank 522 descends, and the positioning assembly 53 retracts, allowing the forklift to unload the roller.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
