Description

Technical Field

[0001] This utility model relates to the field of anilox roller cleaning technology for printing presses, and more particularly to an anilox roller cleaning device for flexographic printing presses. Background Technology

[0002] In flexographic printing equipment, the anilox roller is often referred to as the "heart" of the flexographic printing press, highlighting its crucial role. The anilox roller's function is to transfer ink, thereby transferring the text and images from the printing plate to the substrate. After a period of use, the anilox roller needs to be disassembled and cleaned to remove any ink residue adhering to its surface.

[0003] The prior art, Chinese utility model with publication number CN214188942U, discloses a cleaning device for an anilox roller of a flexographic printing press. The dirt on the surface of the anilox roller 18 is scraped off by a doctor blade, then sprayed and cleaned by a spraying device, and finally dried.

[0004] In the existing technology, after fixing the anilox roller, it is directly scraped and rinsed. However, the ink residue still attached to the surface of the anilox roller is directly rinsed away, which is a waste of resources. Therefore, we designed a method to recycle the residual ink on the surface before rinsing, which not only reduces resource waste but also saves costs. Utility Model Content

The main rotating shaft is connected to the output end of the motor.

[0008] The main fixing component consists of a fixing base and a positioning part. Multiple positioning parts are installed on the wall of the fixing groove provided on the fixing base. Each positioning part consists of an adjusting screw and a pressure plate. The adjusting screw is threaded into a threaded hole provided on the fixing base, and a pressure plate is provided at the end of the adjusting screw.

[0009] The secondary fastener has the same structure as the main fastener.

[0010] The ink recycling mechanism includes an electric telescopic rod, a rubber scraper, a recycling filter, and a recycling box.

The lower end of the moving block is located in the moving slot, and the upper end of the moving block is connected to the support frame.

[0013] The rinsing assembly includes a liquid supply tank, a spray plate, nozzles, a waste liquid filter, and a cleaning scraper. The liquid supply tank is located on top of the protective cover. The outlet of the liquid supply tank is connected to the spray plate via a spray pump. Multiple nozzles are arranged below the spray plate, and the nozzles are connected to the inner cavity of the spray plate. A waste liquid filter is located below the nozzles and is installed at the opening of a waste liquid recovery tank on the base. The cleaning scraper is installed on the inner wall of the protective cover.

[0014] The drying assembly consists of an exhaust fan, a heating chamber, and an exhaust pipe. The exhaust fan and the heating chamber are both installed above the protective cover. The exhaust fan's outlet is connected to the heating chamber's inlet. The heating chamber's outlet is connected to the exhaust pipe.

[0018] Furthermore, the inner wall of the heating chamber is equipped with electric heating wires, which turn the air passing through the heating chamber into hot air. This hot air is blown onto the surface of the anilox roller through a branch outlet pipe, thereby drying the washed anilox roller.

[0019] Furthermore, a control panel is installed on the outside of the protective cover, through which the operation of the device is controlled.

[0020] The beneficial effects of this utility model are:

[0021] This invention designs an ink recycling mechanism. The two ends of the anilox roller are fixed to it by the fixing parts on the support frame. The rubber scraper is moved down to be in close contact with the anilox roller by the electric telescopic rod. The anilox roller rotates under the drive of the motor. The rubber scraper scrapes off the ink on its surface. The ink accumulated on the rubber scraper falls into the recycling box below due to gravity and is recycled. This not only reduces resource waste but also saves costs.

[0022] In the cleaning device designed in this utility model, after recovering the residual ink on the surface of the anilox roller, the drive motor in the moving drive mechanism drives the lead screw to rotate, causing the moving block to move axially, which in turn moves the support frame and the anilox roller fixed on the support frame to a position below the rinsing and drying components. One side of the anilox roller will then contact the cleaning scraper installed on the inner wall of the protective cover. The spray pump is then activated to rinse the anilox roller through the spray nozzle. At this time, the anilox roller rotates under the drive of the motor, realizing the simultaneous rinsing and scraping operation on the outer wall of the anilox roller, thereby improving the cleaning efficiency.

Multiple branch air outlet pipes 44 are arranged at intervals on the outer side of the air outlet pipe 43. The inner wall of the heating box 42 is equipped with electric heating wires, so that the air passing through the heating box 42 becomes hot air. This hot air is blown onto the surface of the anilox roller 100 through the branch air outlet pipes 44 to dry the washed anilox roller 100.

[0035] like Figure 1 and 3 The support frame 6 for mounting the anilox roller 100 is set on the base 1. The bottom ends of the support frame 6 are respectively connected to the slider 63. The slider 63 is slidably connected to the slide rail 64. The slide rail 64 is fixedly installed on the base 1. One end of the support frame 6 is connected to the main fixing component via the main rotating shaft, and the other end is connected to the secondary fixing component via the secondary rotating shaft. The main rotating shaft is connected to the output end of the motor 7, so that the motor 7 drives the main fixing component to rotate. The main fixing component and the secondary fixing component have the same structure. The main fixing component consists of a fixing seat 61 and a positioning part. Multiple positioning parts are installed on the groove wall of the fixing groove provided on the fixing seat 61. The positioning part consists of an adjusting screw 621 and a pressure plate 622. The adjusting screw 621 is threadedly connected to the threaded hole provided on the fixing seat 61, and the end of the adjusting screw 621 is provided with a pressure plate 622.

[0036] like Figure 4 One end of the support frame 6 is connected to the moving block 53 in the moving drive mechanism. The other end of the moving block 53 extends into the moving groove 12 provided on the base 1 and is threadedly connected to the lead screw 52 in the moving groove 12. The lead screw 52 is installed in the moving groove 12 through a bearing, and one end of the lead screw 52 is connected to the output end of the drive motor 51.

[0037] like Figure 1The protective cover 2 has an ink recovery mechanism at its front end, and a lifting baffle is installed between the ink recovery mechanism and the rinsing assembly. The electric telescopic rod 81 in the ink recovery mechanism is fixed to the protective cover 2 by a mounting base. The telescopic end of the electric telescopic rod 81 is connected to the mounting plate 811, and a rubber scraper 82 is installed below the mounting plate 811. The recovery filter screen 83, which filters the ink that falls into the recovery box 84, is installed at the upper opening of the recovery trough on the base 1, and the recovery box 84 is provided in the recovery trough of the base 1.

[0038] The lifting baffle consists of a multi-stage electric telescopic rod 91 and a baffle 92. The multi-stage electric telescopic rod 91 is installed on the side of the protective cover 2 through a fixing plate. The telescopic end of the multi-stage electric telescopic rod 91 is connected to the baffle 92 through a connecting plate 911. The baffle 92 passes through the through hole provided at the top of the protective cover 2 and extends into the protective cover 2. The baffle 92 is made of transparent material, which not only reduces liquid splashing into the recycling box during spraying, but also makes it easy to see the internal cleaning status from the outside.

[0039] Furthermore, a control panel 101 is installed on the outside of the protective cover 2, and the operation of this utility model is controlled through the control panel 101.

[0040] Example 2

[0041] When using this invention, firstly, the anilox roller 100, removed from the printing press, is installed on the support frame 6. Both ends of the anilox roller 100 are inserted into the fixing seats 61 of the fixing component. By adjusting the adjusting screws 621 in the three sets of positioning parts, the pressure plate 622 abuts against the outer wall at the end of the anilox roller 100, thus fixing it to the support frame 6. The motor 7 drives the main rotating shaft to rotate, thereby causing the main fixing component to rotate, which in turn drives the anilox roller 100 to rotate.

[0042] After the anilox roller 100 is installed, the electric telescopic rod 81 in the ink recovery mechanism is activated, which controls the rubber scraper 82 to move down to be in close contact with the outer wall of the anilox roller 100. The anilox roller 100 rotates under the drive of the motor 7, and the rubber scraper 82 in close contact with it scrapes off the ink remaining on its surface. The ink accumulated on the rubber scraper 82 will fall into the recovery box 84 below due to gravity to complete the recovery, which not only reduces resource waste but also saves costs.

[0043] After the residual ink on the outer wall of the anilox roller 100 is recovered, the drive motor 51 in the moving drive mechanism drives the lead screw 52 to rotate, causing the moving block 53 threaded on the lead screw 52 to move axially, thereby driving the entire support frame 6 and the anilox roller 100 to move backward, moving to below the rinsing assembly and the drying assembly. One side of the anilox roller 100 will come into contact with the cleaning scraper 31 installed on the inner wall of the protective cover 2. Then, the spray pump in the rinsing assembly is started, and the anilox roller 100 is rinsed through the nozzle 34. At the same time, the motor 7 is started, causing the anilox roller 100 to rotate under the drive of the motor 7, realizing the simultaneous rinsing and scraping operation on the outer wall of the anilox roller 100, improving the cleaning efficiency.

[0044] After cleaning, the exhaust fan 41 and heating box 42 in the drying assembly are started. The exhaust fan 41 draws air into the heating box 42. The electric heating wire in the heating box 42 is energized and heats up, so that the gas passing through the heating box 42 becomes hot air. The hot air is blown onto the surface of the anilox roller 100 through the branch air outlet pipe 4 to dry it.

[0045] After drying is completed, the drive motor 51 controls the anilox roller 100 to return to its initial position. The operator removes the cleaned and dried anilox roller 100, and then installs the next one to be cleaned, starting the next round of operation.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
