Description

Technical Field

[0001] This utility model belongs to the field of flexographic printing press technology, and more specifically, it relates to an anilox roller structure for a flexographic printing press. Background Technology

[0002] In the process of processing cigarette inner liner paper and tipping paper, flexographic printing presses are required for pattern printing. The anilox roller of the flexographic printing press is the core component for realizing quantitative ink transfer in the flexographic printing system. Its design and performance directly determine the printing quality and efficiency. The surface of the anilox roller is uniformly distributed with micron-sized ink pores, usually engraved at a 45° spiral angle. These pores complete the ink transfer through ink storage, ink distribution, and quantitative ink transfer. The existing flexographic printing press anilox roller generally consists of the anilox roller body and the connecting shaft connected to the printing press.

[0003] Existing application number: CN202223077989.5, this utility model discloses an anilox roller structure for a flexographic printing press, including an anilox roller, a fixed shaft, an adjusting shaft, a connecting shaft, gears, and a motor; the fixed shaft is provided at both ends of the anilox roller, and the adjusting shaft is circumferentially limited and axially retractable at the ends of the fixed shafts at both ends; the connecting shaft is rotatably provided on the frame at both ends of the anilox roller, and the outer ends of the adjusting shafts at both ends are circumferentially limited and extend into the connecting shafts; the motor passes through one side of the frame, and the gears meshing with the fixed shaft on the motor shaft and the corresponding side of the fixed shaft are provided. This application can realize quick installation and disassembly between the anilox roller and the frame, improve the installation and disassembly efficiency of the anilox roller, and facilitate daily cleaning, maintenance, or replacement of the anilox roller.

[0004] Based on the above, if the interval between the replacement of the anilox roller of a flexographic printing press and the subsequent cleaning is too long, the ink remaining on the surface of the anilox roller will quickly come into contact with the air and solidify, adhering to the surface of the anilox roller and the cells, forming a dry plate layer that is difficult to clean. This not only increases the difficulty of subsequent cleaning, but also easily clogs the cells, affecting the ink transfer accuracy and quality of subsequent printing. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a structure for anilox rollers in flexographic printing presses. This solves the problem that when replacing anilox rollers in existing flexographic printing presses, if the interval between disassembly and subsequent cleaning is long, residual ink on the anilox roller surface will quickly come into contact with air and solidify, adhering to the anilox roller surface and cells, forming a dry plate layer that is difficult to clean. This not only increases the difficulty of subsequent cleaning but also easily clogs the cells, affecting the ink transfer accuracy and quality of subsequent printing.

[0006] The purpose and effect of this utility model's anilox roller structure for a flexographic printing press are achieved through the following specific technical means:

[0007] A structure for an anilox roller in a flexographic printing press includes a connecting shaft, an anilox roller body, a first connecting plate, a second connecting plate, a first fixing magnet, an instant cleaning component, and an auxiliary cleaning component. The anilox roller body is coaxially fixedly connected to the outside of the connecting shaft. The first connecting plate is fixedly connected to the outside of the left end of the connecting shaft. The second connecting plate is coaxially fixedly connected to the outside of the right end of the connecting shaft. Two sets of the first fixing magnet are provided, with two magnets in each set, and the two sets of first fixing magnets are respectively fixedly connected to the inside of the first and second connecting plates. The instant cleaning component is located on the outside of the connecting shaft. The auxiliary cleaning component is located inside the anilox roller body.

[0008] Furthermore, the instant cleaning component includes: a first fixing ring and a cleaning brush; the first fixing ring is disposed on the right side of the first connecting plate; the cleaning brush is fixedly connected inside the first fixing ring.

[0009] Furthermore, the instant cleaning component also includes: a second retaining ring and a wiping sponge; the second retaining ring is disposed on the left side of the second connecting plate; the wiping sponge is fixedly connected inside the second retaining ring.

[0010] Furthermore, the instant cleaning component also includes: docking slots and second fixing magnets; four docking slots are provided, and the four docking slots are respectively provided inside the first fixing ring and the second fixing ring, and four first fixing magnets are respectively inserted into the four docking slots; four second fixing magnets are provided, and the four second fixing magnets are respectively fixedly connected to the four docking slots.

[0011] Furthermore, the auxiliary cleaning component includes a heating tube and a power interface; the heating tube is wound around and fixed inside the anilox roller body, and the right end of the heating tube extends out of the anilox roller body; the power interface is fixedly connected to the right end of the heating tube.

[0012] Furthermore, the auxiliary cleaning component also includes: a connecting rope and a sealing cap; the left end of the connecting rope is fixedly connected to the top of the power interface; the sealing cap is rotatably connected to the lower right end of the connecting rope, and the sealing cap is threadedly connected to the outer end of the power interface.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, by setting an instant cleaning component in the anilox roller structure of the flexographic printing press, after the anilox roller body is removed, the ink adhering to the surface of the anilox roller body can be quickly removed by moving and rotating the first fixing ring and using the cleaning ring brush. Then, by moving the second fixing ring, the residual ink can be further absorbed by the wiping sponge. This avoids the situation where the residual ink dries out and clogs the cells during storage or while waiting for cleaning, thus improving the efficiency of the anilox roller body's later maintenance and the ink transfer accuracy of subsequent printing.

[0015] Secondly, an auxiliary cleaning component is added. When the anilox roller body is deeply cleaned, the heating tube is powered by electricity. The heat generated by the heating tube can soften the ink that is solidified on the surface of the anilox roller body and in the cells. Combined with ultrasonic cleaning, the thoroughness of cell cleaning can be significantly improved. This avoids the problem that traditional cleaning methods are unable to remove solidified ink, which leads to a decrease in the ink transfer capacity of the cells and extends the service life of the anilox roller.

[0016] This invention enables rapid and immediate initial cleaning of the disassembled anilox roller body by setting up an instant cleaning component. The addition of an auxiliary cleaning component can improve the thoroughness of cleaning by heating and softening the ink. Together, they improve the maintenance efficiency of the anilox roller body, ink transfer accuracy, and extend service life, providing a more suitable anilox roller maintenance solution for flexographic printing presses, reducing equipment maintenance costs, and achieving more efficient production operations.
