The application provides an anilox roller laser cleaning device, which is used for cleaning an anilox roller 500, and comprises a case 100, a roller group 200 and a laser head 300, as shown in fig. 1 and 2. The roller group 200 is connected to the housing 100, and includes a first rotating roller 210 and a second rotating roller 220, and the first rotating roller 210 and the second rotating roller 220 are arranged in parallel to receive the anilox roller 500. At least one of first live-rollers 210 and second live-rollers 220 is connected with the motor, and then when anilox roller 500 and first live-rollers 210, second live-rollers 220 butt, the rotation of first live-rollers 210 and/or second live-rollers 220 can drive anilox roller 500's rotation, conveniently carries out the washing of circumferential laser 310 to anilox roller 500. In this embodiment, first live-rollers 210 is connected with the motor, can take place to rotate under the motor drives, and then drives anilox roller 500 and takes place to rotate, and second live-rollers 220 rotates with quick-witted case 100 to be connected, and then anilox roller 500 is driven the back by first live-rollers 210, also can drive the rotation of second live-rollers 220 to reduce frictional resistance to anilox roller 500 pivoted influence.

It should be noted that, after the outer circumferential surface of the anilox roller 500 is clamped by the clamping device in the conventional art, the rotation of the clamping device drives the anilox roller 500 to rotate. However, this driving method has a disadvantage that the clamping area between the clamping device and the anilox roller 500 is wrapped by the clamping member, and the laser 310 cannot clean the clamping area, so that the clamping area needs to be replaced in the cleaning process of the anilox roller 500, and all areas on the outer circumferential surface of the anilox roller 500 can be cleaned. In addition, in a large batch of cleaning operations of the anilox roller 500, the anilox roller 500 needs to be continuously clamped, and the assembly and disassembly of the anilox roller 500 takes much time. In this application, through accepting anilox roller 500 with first live-rollers 210 and second live-rollers 220, avoided centre gripping anilox roller 500 to form the clearance dead angle on the one hand, can realize the comprehensive washing of anilox roller 500 outer circumferential surface through anilox roller 500's rotation and laser head 300's removal, need not to carry out substep processing. On the other hand, the assembling and disassembling process of the anilox roller 500 is more convenient, namely the anilox roller 500 is placed on the first rotating roller 210 and the second rotating roller 220, so that the anilox roller 500 can be assembled, the disassembling process is similar, the clamping and locking operation is not needed, the preparation time before processing can be shortened for large-batch cleaning of the anilox roller 500, and the cleaning efficiency is greatly improved.

As shown in fig. 2, a laser head 300 is connected to the cabinet 100, and the laser head 300 is used to emit a laser 310. In this embodiment, the laser head 300 mainly functions to transmit the laser light 310, and the laser light 310 is generated by the laser generator, transmitted through the optical path inside the laser head 300, and then emitted from the light exit hole 320 of the laser head 300. The laser 310 is focused on the surface of the anilox roller 500, and impurities on the surface of the anilox roller 500 can be broken by energy flow and then fall off, so that the cleaning purpose is achieved. Be different from traditional setting up laser head 300 in the top of anilox roller 500 or with laser head 300 and anilox roller 500 parallel and level setting, in this application, laser head 300 is located between first rotating roller 210 and the second rotating roller 220, and is located the below of first rotating roller 210 and second rotating roller 220 has the clearance between first rotating roller 210 and the second rotating roller 220, and under operating condition, laser 310 that laser head 300 sent can pass this clearance and reach the surface of anilox roller 500, and then realizes the cleaning operation to anilox roller 500 surface. The laser head 300 can move in the axial direction of the roller set 200, that is, in the length direction of the anilox roller 500, thereby performing the cleaning of the anilox roller 500 in the length direction.

It should be noted that the laser 310 has a certain focal depth, and a better cleaning effect can be achieved within the focal depth range, and further, when the change of the outer diameter of the anilox roller 500 is within a certain range, the position of the laser head 300 does not need to be adjusted to enable the surface of the anilox roller 500 to be located within the focal length of the laser 310, and for convenience of subsequent description, the outer diameter range of the anilox roller 500 which can be cleaned by the anilox roller laser cleaning device is called as a cleaning range under the condition that the vertical position of the laser head 300 and the parameters of the laser 310 are not changed. In this application, because laser head 300 is located anilox roller 500's below, the anilox roller 500 of different external diameters is accepted the back by first rotating roller 210 and second rotating roller 220, its minimum is not big to laser head 300's distance change, and even if laser head 300 is at the ascending position determination of vertical side, also can obtain great washing scope, compare in the top or the side direction with laser head 300 setting at anilox roller 500, set up laser head 300 and can obtain bigger washing scope in anilox roller 500's below, and then when wasing the anilox roller 500 of different specifications, as long as satisfy anilox roller 500's external diameter size in the washing scope, need not to adjust laser 310 parameter or adjustment laser head 300 position promptly.

Based on the above, the anilox roller laser cleaning equipment of this application is applicable to the washing of big batch anilox roller 500, need not to carry out the centre gripping locking of anilox roller 500 or remove locking operation, only needs to pack into or pull down anilox roller 500 from roller train 200 and can accomplish anilox roller 500's loading and unloading operation, has greatly improved anilox roller 500's handling efficiency, and need not to clear up the dead angle, need not to divide the work step operation, has greatly shortened long when single anilox roller 500's washing. Because the laser head 300 is located at the lower side of the anilox roller 500, the anilox roller laser cleaning equipment has a large cleaning range, and can reduce the operation of adjusting the parameters of the laser 310 or the position of the laser head 300 when cleaning large batches of anilox rollers 500 of various specifications, thereby greatly shortening the early-stage preparation time of the cleaning operation of the anilox roller 500.

In some embodiments, as shown in fig. 2 and 3, to obtain a larger cleaning range, the perpendicular bisector of the line connecting the centers of the first rotating roller 210 and the second rotating roller 220 coincides with the optical path of the laser 310, and thus the laser 310 can be irradiated to the lowest point of the anilox roller 500 when the anilox roller 500 is mounted on the roller group 200. For the sake of convenience, the following description is given by way of an example of an embodiment with specific values, but it should not be understood that the present application only protects the anilox roller laser cleaning apparatus which is suitable for this set of values. In some embodiments, the diameter a of the first rotating roller 210 and the second rotating roller 220 is 76mm, the center distance b of the first rotating roller 210 and the second rotating roller 220 is 85mm, the focal depth c of the laser 310 is 12mm, and further, the cleaning range of the laser cleaning equipment for the anilox roller under the specification parameters is phi 50-phi 300, that is, after the anilox roller 500 with the outer diameter ranging from 50mm to 300mm is mounted on the roller group 200, a good cleaning effect can be obtained without adjusting the position of the laser head 300 or the parameters of the laser 310. Specifically, the minimum diameter of the anilox roller 500 is set to d1, the maximum diameter of the anilox roller 500 is set to d2, the vertical distance from the lowest point of the anilox roller 500 with the minimum diameter to the line connecting the centers of the first rotating roller 210 and the second rotating roller 220 is set to e1, the vertical distance from the lowest point of the anilox roller 500 with the maximum diameter to the line connecting the centers of the first rotating roller 210 and the second rotating roller 220 is set to e2, and e1 and e2 satisfy the following relationships:

Δe＝e2-e1

in the embodiment, d1 is 50mm, d2 is 300mm, a is 76mm, b is 85mm, e1 is 21.51mm, e2 is 33.13mm, the height difference Δ e of the lowest point is 11.62mm, and the focal depth of the laser 310 is 12mm by substituting the above formula, when the anilox roller laser cleaning equipment firstly processes the anilox roller 500 with the diameter of 50mm, the laser head 300 is adjusted to the limit position where the anilox roller 500 is located in the focal depth of the laser 310 and the laser head 300 is closest to the anilox roller 500, and in the subsequent processing process of the anilox roller 500 with the diameter of 50mm to 300mm, the anilox roller 500 can be located in the focal depth of the laser 310 without adjusting the parameters of the laser head 300 or the laser 310. On the contrary, when the anilox roller laser cleaning equipment firstly processes the anilox roller 500 with the specification of 300mm, the laser head 300 is adjusted to the limit position where the anilox roller 500 is positioned in the focal depth of the laser 310 and the laser head 300 is farthest from the anilox roller 500, and the adjustment of the parameters of the laser head 300 or the laser 310 is not needed in the subsequent processing process.

From the above formula or its deformation formula, when cleaning a large batch of anilox rollers 500, the following ideas can be adopted to process the anilox rollers 500:

selecting the anilox roll 500 with the smallest diameter of the batch of anilox rolls 500 (determining the smallest diameter d 1);

selecting a first rotating roller 210 and a second rotating roller 220 with proper outer diameters to receive the anilox roller 500 (determining a rotating roller diameter a and a center distance b);

selecting appropriate laser 310 processing parameters (determining depth of focus c);

adjusting the laser head 300 to the limit position where the anilox roller 500 is positioned in the focal depth of the laser 310 and the laser head 300 is closest to the anilox roller 500 for processing (determining the minimum vertical distance e 1);

measuring the maximum diameter of the workable anilox roll 500 (calculating the maximum diameter d 2);

machining an anilox roll 500 having a diameter in the range of a minimum diameter d1 to a maximum diameter d 2;

the anilox roll 500 with the smallest diameter of the remaining unwashed anilox rolls 500 is selected, the appropriate laser 310 processing parameters or the specifications of the rotating rolls are reselected, and the above steps are repeated.

Based on the above, through the arrangement of the processing sequence, the anilox rollers 500 of various specifications can be classified and processed, the anilox rollers 500 of the same type can be directly installed on the roller group 200 to be cleaned and processed by the laser 310, the laser 310 processing parameters do not need to be debugged, the preparation time before the laser 310 is cleaned is greatly shortened, and the processing efficiency is improved.

In order to show the advantages of the anilox roller laser cleaning apparatus and the above-described processing method in the present application, a comparative example will be described herein of the processing when the laser head 300 is positioned above the anilox roller 500. As shown in fig. 4, the vertical distance from the highest point of the minimum diameter anilox roller 500 to the line connecting the centers of the first and second

rotating rollers

210 and 220 is set as e3, the vertical distance from the highest point of the maximum diameter anilox roller 500 to the line connecting the centers of the first and second

rotating rollers

210 and 220 is set as e4, and e3 and e4 satisfy the following relationship:

Δe＝e4-e3

the parameters in this comparative example were all kept the same as those in the above example, d1 was 50mm, d2 was 300mm, a was 76mm, and b was 85mm, and by substituting the above formula, it was possible to calculate that e3 was 71.51mm, e2 was 333.13mm, and the height difference Δ e at the highest point was 261.62mm, and the height difference in the comparative example was changed by only 11.62mm compared to the height difference at the lowest point in the above example, and the height difference in the comparative example was greatly changed, so it was necessary to readjust the position of the laser head 300 to ensure that the surface of the anilox roller 500 was within the depth of focus of the laser light 310.

Based on the comparison between the above comparative example and the embodiment, it can be seen that in the present application, the light path of the laser 310 is adjusted to coincide with the perpendicular bisector of the central connecting line of the roller set 200, so that the laser 310 irradiates on the lowest point of the anilox roller 500, and further, when a workpiece in a certain range is processed, the cleaning process can be directly performed without adjusting the parameters of the laser 310, thereby improving the processing efficiency.

In some embodiments, the anilox roller laser cleaning apparatus includes two sets of roller sets 200 respectively disposed at both ends of the cabinet 100 in an axial direction of the roller sets 200, and a distance between the roller sets 200 can be adjusted. In this embodiment, as shown in fig. 5, the roller set 200 at the left end is a fixed roller set 230, and is fixedly connected to the chassis 100. The roller set 200 at the right end is a movable roller set 240, is movably connected with the case 100, and can move along the length direction of the anilox roller 500, so that the distance between the roller sets 200 can be properly adjusted according to the length of the anilox roller 500. When the anilox roller 500 is loaded, the left end of the anilox roller 500 is placed on the fixed roller set 230 at the left end, and the right end of the anilox roller is received by the movable roller set 240, so that the laser head 300 moves between the fixed roller set 230 and the movable roller set 240 to clean the anilox roller 500. In this embodiment, the movable roller set 240 can feed back to the laser head 300 according to the adjustment of the length of the anilox roller 500, so that the laser head 300 moves a corresponding distance according to the length of the anilox roller 500, thereby preventing the laser head 300 from moving too long along the length direction of the anilox roller 500, avoiding the situation of 'idle running' without irradiating the anilox roller 500, shortening the moving stroke of the laser head 300, and improving the effective work rate of the laser 310.

In some embodiments, as shown in fig. 6, the anilox roller laser cleaning device comprises a fine adjustment structure 400, wherein the fine adjustment structure 400 is abutted against the bottom surface of the laser head 300, and the position of the laser head 300 in the vertical direction can be adjusted. The fine adjustment structure 400 mainly plays a role in fine adjustment, when the maximum diameter and the minimum diameter of the anilox roller 500 are too large, the focal depth of the laser 310 cannot be covered, or the surface pattern on the anilox roller 500 is too deep, so that the focal depth of the laser 310 is exceeded, the fine adjustment structure 400 can perform fine adjustment on the laser head 300 in the vertical direction, so that the surface of the anilox roller 500 is located in the focal depth of the laser 310. When a large range of displacement is required, the displacement is still performed using the driving structure to which the laser head 300 is connected. The driving structure comprises a screw motor and an optical axis, and can move in three degrees of freedom to adjust the position of the laser head 300.

In some embodiments, as shown in fig. 6, the anilox laser cleaning apparatus further comprises a distance sensor 410 disposed on the top surface of the laser head 300 to measure the vertical distance between the anilox roller 500 and the laser head 300. When the workpiece surface is detected to be outside the focal depth coverage, the distance sensor 410 can give an electrical signal feedback to the fine adjustment structure 400 or the driving structure to automatically adjust the position of the laser head 300 so that the surface of the anilox roller 500 can be cleaned.

In some embodiments, as shown in fig. 6, the laser head 300 has a light exit hole 320 formed on the top surface thereof, and the laser 310 is emitted from the light exit hole 320. The anilox roller laser cleaning apparatus further comprises an air knife 460, the air knife 460 is disposed at one side of the top surface and can form an air flow parallel to the top surface to prevent dust from falling into the light exit hole 320 under the action of gravity when the laser 310 is cleaned.

In some embodiments, as shown in fig. 6, the anilox roller laser cleaning apparatus further includes a blocking cover 420, the blocking cover 420 is rotatably connected to the laser head 300, when the laser head 300 stops working, the blocking cover 420 can rotate to cover the light outlet 320 to prevent dust or other impurities from falling into the light outlet 320, and when the laser head 300 performs cleaning work, the blocking cover 420 can rotate to expose the light outlet 320 to prevent blocking of the light path. In other embodiments, a motor is additionally installed on the blocking cover 420, and the rotation of the motor is controlled by a switch, so that when the laser head 300 starts to work, the blocking cover 420 automatically rotates to expose the light emitting hole 320, and after the laser head 300 stops working, the blocking cover 420 automatically closes to prevent dust from falling.

In some embodiments, a protection lens is disposed on the light exit hole 320 to prevent dust from falling into the light exit hole 320, so that the laser 310 can be transmitted while blocking the dust. However, the dust adhered to the lens tends to increase the temperature of the lens and even melt the lens. In this embodiment, in order to prevent this situation, as shown in fig. 6, the anilox roller laser cleaning device further includes a temperature sensor 430, and the optical path of the infrared temperature sensor 430 is aligned with the lens, so as to monitor the temperature of the lens, and feed back to the control center of the anilox roller laser cleaning device in real time.

In some embodiments, the anilox roller laser cleaning apparatus comprises a dust recovery device for recovering dust within the cabinet 100. The dust recovery device is arranged opposite to the air knife 460, an air pump is connected outside the dust recovery device and can form relative negative pressure, then the air flow moves along the direction from the air knife 460 to the dust recovery device, and finally the air flow is sucked into the dust recovery device for centralized processing.
