Description

Technical Field

[0001] This utility model belongs to the technical field of anilox roller cleaning equipment, specifically relating to an automatic anilox roller cleaning device. Background Technology

[0002] As a key component in printing processes such as flexographic and gravure printing, the state of the cells on the anilox roller directly affects the amount of ink transferred and the printing quality. Over long-term use, ink and impurities can accumulate on the surface of the anilox roller. If not cleaned promptly, this will not only reduce printing quality and shorten the roller's lifespan but may also lead to production stoppages.

[0003] However, existing anilox rollers are mainly cleaned manually, which is labor-intensive, inefficient, and the cleaning effect is difficult to guarantee, and it is also easy to damage the surface of the anilox roller. Therefore, there is an urgent need for an automatic anilox roller cleaning device that can guarantee the cleaning effect and improve the cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic cleaning device for anilox rollers, which solves the problems of low efficiency, poor effect and easy damage to the surface of anilox rollers caused by improper operation in the existing manual cleaning of anilox rollers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic cleaning device for anilox rollers, including a cleaning box with a drain outlet at the bottom, a limiting groove for overlapping anilox rollers on the cleaning box, and a first driving mechanism on the cleaning box that can dock with the anilox rollers and drive the anilox rollers to rotate.

[0006] The anilox roller, which is attached to the limiting groove, has a transfer frame suspended above it that can move horizontally along the axial direction of the anilox roller. The transfer frame is equipped with a nozzle for spraying liquid toward the surface of the anilox roller. The transfer frame is also equipped with a rotatable mounting plate. Multiple brush heads that can be rotated to the top of the anilox roller are floating vertically on the mounting plate. When the brush head moves to the top of the anilox roller, it can move under the drive of a second drive mechanism to contact the surface of the anilox roller.

[0007] Optionally, a transfer plate is slidably provided on the cleaning machine housing along the moving direction of the transfer frame, and a limiting support frame capable of overlapping the anilox roller is provided on the transfer plate.

[0008] Optionally, the transfer frame is provided with a first servo motor, and the mounting plate is located at the output end of the first servo motor.

[0009] Optionally, the brush head is connected to the moving end of the floating component, and the transfer frame is provided with a drive cylinder located above the floating component. The floating component includes a fixed seat provided on the mounting plate, a floating rod that moves vertically through the fixed seat, and a return spring sleeved on the outer periphery of the floating rod. The brush head is provided at the bottom end of the floating rod.

[0010] The two ends of the return spring are supported by the fixed base and the floating rod, respectively. The output end of the drive cylinder can press down on the top of the floating rod, and the floating rod can compress the return spring when it moves downward.

[0011] Optionally, the bottom end of the floating rod is connected to a first clamping block, and a second clamping block is detachably connected to the first clamping block by bolts, and the first clamping block and the second clamping block can clamp the brush head.

[0012] Optionally, the first drive mechanism includes a second servo motor and a quick-release chuck connected to the second servo motor, the quick-release chuck being capable of clamping the end of the anilox roller.

[0013] Optionally, the transfer plate and the cleaning chamber are slidably connected via linear guide rails.

[0014] Optionally, the second drive mechanism is a servo slide, and the transfer frame is connected to a slider on the servo slide.

[0015] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: the brush head, driven by the second drive mechanism, can contact the surface of the anilox roller. As the anilox roller rotates and the liquid sprayed from the nozzle towards it, the brush head continuously rubs against the surface of the anilox roller, thus cleaning it. Simultaneously, as the transfer frame moves axially along the anilox roller, the brush head can thoroughly clean the surface of the anilox roller, improving efficiency and enhancing the cleaning effect.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] like Figures 1-2 As shown, an automatic cleaning device for anilox rollers includes a cleaning housing 1 with a drain outlet 101 at the bottom. The cleaning housing 1 has a limiting groove 102 for overlapping the anilox roller 3, and a first drive mechanism on the cleaning housing 1 capable of docking with the anilox roller 3 and driving the anilox roller 3 to rotate. Specifically, the anilox roller 3 can be overlapped in the limiting groove 102 on the cleaning housing 1 manually or by a robot, and one end of the anilox roller 3 can dock with the first drive mechanism, enabling the first drive mechanism to drive the anilox roller 3 to rotate. Meanwhile, in this technical solution, the anilox roller 3, which is attached to the limiting groove 102, is suspended above a transfer frame 4 that can move horizontally along the axial direction of the anilox roller 3. The transfer frame 4 is equipped with a nozzle (not shown in the figure) for spraying liquid toward the surface of the anilox roller 3. The nozzle is connected to the output end of a water pump in the prior art through a corrugated pipe, water pipe, etc., and the water inlet end of the water pump can be connected to a cleaning agent, clean water, or other liquid used for cleaning the anilox roller 3. The sprayed liquid can be collected by the cleaning machine box 1 and discharged centrally through the drain outlet 101. Furthermore, the transfer frame 4 is equipped with a rotatable mounting plate 5, on which multiple brush heads 6 are vertically floating and can be rotated to be above the anilox roller 3. It should be noted that the nozzles can spray liquid onto the surface of the anilox roller 3 that contacts the brush head 6, and the multiple brush heads 6 can be made of different materials and can also be set in different shapes and sizes. When the brush head 6 moves above the anilox roller 3, it can move under the drive of the second drive mechanism to contact the surface of the anilox roller 3, so that different brush heads 6 can be selected for cleaning the anilox roller 3 according to different scenarios, thereby improving the flexibility of the device.

[0022] In actual operation, the scrubbing head 6, driven by the second drive mechanism, comes into contact with the surface of the anilox roller 3. As the anilox roller 3 rotates and the spray nozzles spray liquid towards it, the scrubbing head 6 continuously rubs against the surface of the anilox roller 3, thus scrubbing its surface. Simultaneously, as the transfer frame 4 moves axially along the anilox roller 3, the scrubbing head 6 can thoroughly scrub the surface of the anilox roller 3, improving efficiency and enhancing the cleaning effect.

[0023] Furthermore, such as Figure 1 As shown, a transfer plate 7 is slidably mounted on the cleaning housing 1 along the moving direction of the transfer frame 4. A limiting support frame 8 is mounted on the transfer plate 7 to overlap the anilox roller 3, allowing the position of the limiting support plate to be adjusted according to the length of the anilox roller 3, thereby improving the flexibility of the device. Simultaneously, the transfer plate 7 is slidably connected to the cleaning housing 1 via a linear guide rail 18 to improve the accuracy of the linear movement of the transfer plate 7.

[0024] It should be noted that the aforementioned limiting support frame 8 is also provided with limiting grooves 102 for overlapping the anilox roller 3, and the limiting grooves 102 on the limiting support frame 8 are coaxially arranged with the limiting grooves 102 on the cleaning machine housing 1 to ensure the uniqueness of the position when the anilox roller overlaps on the limiting grooves 102. Meanwhile, in practical applications, the bearings at both ends of the anilox roller 3 can be movably embedded in the limiting grooves 102 to improve the smoothness of the rotation of the anilox roller 3 and enhance its rotational stability.

[0025] Furthermore, such as Figure 2 As shown, the brush head 6 is connected to the moving end of the floating component. A drive cylinder 13 is mounted on the transfer frame 4 above the floating component. The floating component includes a fixed base 10 mounted on the mounting plate 5, a floating rod 11 that moves vertically through the fixed base 10, and a return spring 12 sleeved around the outer periphery of the floating rod 11. The brush head 6 is located at the bottom end of the floating rod 11. The two ends of the return spring 12 are supported by the fixed base 10 and the floating rod 11, respectively. The output end of the drive cylinder 13 can press down on the top of the floating rod 11, and when the floating rod 11 moves downward, it can compress the return spring 12. When the output end of the drive cylinder 13 retracts, the floating rod 11 can return to its original position under the support of the return spring 12. It should be noted that... Figure 2As shown, in this technical solution, the fixed base 10 includes a first fixed block and a second fixed block, which are fixed together by bolts. A stepped groove is provided on the first fixed block. A limiting ring is provided on the outer periphery of the floating rod 11. The floating rod 11 can slide along the stepped groove, but the limiting ring on the floating rod 11 abuts against the cross-sections at both ends of the sliding groove when the floating rod 11 slides along the stepped groove, thereby limiting the movement distance of the floating rod 11. One end of the return spring 12 abuts against the limiting ring on the floating rod 11, and the other end abuts against the cross-section of the stepped groove. Furthermore, when the first fixed block and the second fixed block surround the outer periphery of the floating rod 11, the floating rod 11 cannot detach from the fixed base 10.

[0026] Furthermore, such as Figure 1 As shown, a first servo motor 9 is provided on the transfer frame 4, and the mounting plate 5 is located at the output end of the first servo motor 9. The first servo motor 9 is existing technology and can drive the mounting plate 5 to rotate at any angle, so that any floating component set on the mounting plate 5 can rotate to below the output end of the drive cylinder 13, so that the output end of the drive cylinder 13 can press down the floating rod 11 on the floating component, so that the brush head 6 set on the floating rod 11 can contact the surface of the anilox roller 3.

[0027] The above, such as Figure 2 As shown, the bottom end of the floating rod 11 is connected to the first clamping block 14, and the second clamping block 15 is detachably connected to the first clamping block 14 by bolts. The first clamping block 14 and the second clamping block 15 can clamp the brush head 6 to facilitate the replacement of the brush head 6.

[0028] In this embodiment, the first driving mechanism includes a second servo motor 16 and a quick-release chuck 17 driven and connected to the second servo motor 16. The quick-release chuck 17 is capable of clamping the end of the anilox roller 3. The quick-release chuck 17 is existing technology and can quickly clamp the end of the anilox roller 3. It should be noted that the quick-release chuck 17 is driven and connected to the second servo motor 16, meaning that the quick-release chuck 17 and the second servo motor 16 are driven by mechanical transmission components, including but not limited to gears, chains, synchronous pulleys, and synchronous belts, so that the second servo motor 16 can drive the anilox roller 3 to rotate via the quick-release chuck 17.

[0029] Furthermore, the second drive mechanism is a servo slide 19, which is existing technology, and the transfer frame 4 is connected to the slider 20 on the servo slide 19 to improve the stability of the transfer frame 4 movement and the accuracy of linear motion.

[0030] Working principle: First, the anilox roller 3 can be manually or robotically placed into the limiting groove 102 on the cleaning machine housing 1, with one end of the anilox roller 3 engaging with the quick-release chuck 17. Then, the second servo motor 16 drives the anilox roller 3 to rotate. Next, according to process requirements, a suitable brush head 6 is selected, and the first servo motor 9 drives the mounting plate 5 to rotate, causing the floating component with the suitable brush head 6 to rotate below the output end of the drive cylinder 13. Then, the drive cylinder 13 presses down the floating rod 11 on the floating component, causing the brush head 6 on the floating rod 11 to contact the surface of the anilox roller 3. Subsequently, the servo slide 19 drives the transfer table to move along the axial direction of the anilox roller 3. With the rotation of the anilox roller 3 and the liquid sprayed from the nozzle towards the anilox roller 3, the brush head 6 continuously rubs against the surface of the anilox roller 3, allowing the brush head 6 to thoroughly clean the surface of the anilox roller 3, improving efficiency and enhancing the cleaning effect.

[0031] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
