[0001] The utility model relates to the technical field of gravure printing machines, in particular to an aluminum film balloon gravure printing machine with a replaceable gravure cylinder mechanism. Background Art

[0002] A gravure printing press is a machine that uses a gravure plate for printing, and is mainly used for flexible packaging printing. During the printing process, the gravure printing press uses specific mechanism designs, such as a gravure plate holder, a rotating motor, and an ink tank, to achieve uniform ink supply and precise movement of the printing roller, thereby completing high-quality printing tasks. This type of printing press has the characteristics of high working efficiency and good printing quality, and during the design and manufacturing process, it continuously meets the diverse needs of consumers through technological innovation and upgrading. As an important printing equipment, the gravure printing press plays a vital role in the field of packaging printing.

[0003] In the prior art, traditional gravure printing machines require manual disassembly of the roller when changing the printing pattern, which consumes a lot of time and manpower, has low work efficiency, and cannot guarantee the installation accuracy of the printing roller during replacement, which may cause deviations in subsequent printing. Utility Model Content

[0004] The utility model discloses an aluminum film balloon gravure printing machine with a replaceable gravure roller mechanism, aiming to solve the technical problems that a traditional gravure printing machine needs to manually disassemble the roller when replacing a printing pattern, has low working efficiency and cannot ensure the installation accuracy of the printing roller.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an aluminum film balloon gravure printing machine with a replaceable gravure roller mechanism, comprising a fixed frame, the outer walls on both sides of the fixed frame are connected to side frames by bolts, the fixed frame and the two side frames are provided with the same positioning and replacement module, and the inner walls on both sides of the fixed frame are connected to the same ink tank by bolts, and the ink tank and the fixed frame are provided with the same ink uniforming module, the positioning and replacement module comprises two mutually symmetrical rotating seats, and the two side frames are provided with mounting holes, the two rotating seats are rotatably connected to the corresponding mounting holes by bearings, the fixed frame is provided with two sliding slots, and the same printing roller is slidably connected in the two sliding slots, the ink uniforming module comprises two mutually symmetrical friction wheels, and the inner walls on both sides of the fixed frame are provided with circular holes, the two friction wheels are rotatably connected to the corresponding circular holes by bearings, the two friction wheels are tightly attached to the outer wall of the printing roller, the outer walls on both sides of the fixed frame are provided with rotation holes, and the two rotation holes are provided with shafts.

[0006] By providing a positioning and replacement module, when the printing roller needs to be replaced, the servo motor is started to rotate the threaded rod, and the bevel gear one is rotated through the meshing of the bevel gear two, so that all the threaded rods are driven to rotate, so that the sliding block slides on the outside of the threaded rod, and the clamping piece is driven to move outward through the connecting rod to release the fixation of the printing roller, and then the hydraulic rod is started to push the support piece, and the printing roller is pushed to slide in the sliding slot through the support wheel. The support wheel can reduce the wear on the outside of the printing roller, push the printing roller out, and continue to push the new printing roller into the sliding slot, so that the printing roller can be automatically and quickly pushed out without manual disassembly, thereby reducing manpower consumption and improving work efficiency. The printing roller slowly reaches the specified position through the hydraulic rod and the support wheel, and the servo motor is started in the reverse direction. The printing roller is driven to the center and then fixed by the clamping piece.

[0008] By providing an ink uniforming module, when the printing roller rotates to start printing, the friction wheel rotates synchronously through the friction between the printing roller, driving the movable rod to reciprocate, and the ink is uniformly stirred by the stirring member. The ink can be stirred while printing to improve its fluidity, thereby ensuring uniform inking of the substrate and improving the printing effect.

[0009] From the above, it can be seen that the aluminum film balloon gravure printing machine with a replaceable gravure cylinder mechanism provided by the utility model can automatically and quickly push out the printing roller through the positioning and replacement module when the printing roller needs to be replaced, without the need for manual disassembly, thereby reducing manpower consumption and improving work efficiency. At the same time, the printing roller can be positioned and fixed after the replacement is completed to avoid its offset and printing deviation. When the fluidity of ink in the ink tank decreases after working for a long time, the ink uniformity module can stir the ink while printing to improve its fluidity, thereby ensuring uniform inking of the substrate and improving the printing effect.
