Description

Technical Field

[0001] The utility model relates to the technical field of printing machinery, and particularly relates to an automatic cleaning device for printing machine ink rollers. Background Technique

[0002] During the printing production process, the ink rollers of the printing machine will continuously accumulate ink and impurities, and need to be cleaned regularly to ensure the printing quality and the normal operation of the equipment. The traditional cleaning method usually involves manual cleaning by personnel using cleaning agents. This method is not only time-consuming and laborious, but also has low efficiency, affecting the production progress of the printing machine. Therefore, it is necessary to design an automatic cleaning device for printing machine ink rollers to improve the cleaning efficiency and production quality of the printing machine ink rollers.

[0003] An automatic cleaning device for printing machine ink rollers with a reference publication number of CN220995876U includes a main box body, a box cover and a water storage tank. This device fills the inside of the cleaning tank with cleaning liquid, and at the same time places the ink roller to be cleaned between the driving roller and the driven roller. Then, by starting the electric telescopic rod to control the fixed plate to move downward, the soft brush is driven to move synchronously to achieve the purpose of limiting the printing machine ink roller. At the same time, after the ink roller cleaning device is cleaned, the first electromagnetic control valve is started to discharge the water with dirt into the inside of the filter tank, and then through various filters with different apertures inside the filter tank to achieve the purpose of filtering the water. Then, by starting the water pump and the second electromagnetic control valve, the filtered water is collected into the inside of the water storage tank for convenient secondary utilization, thereby saving costs and achieving an environmental protection effect at the same time. According to the above, although this device can be well applied, it is usually not convenient to brush the ink rollers simultaneously, so that the cleaning efficiency of the device for the ink rollers is still difficult to reach the established expectation, often troubling the users. Content of the Utility Model

[0025] At the center position of the top end of the I-shaped frame 1 is provided a cleaning tank 2. At the top end of the I-shaped frame 1 on one side of the cleaning tank 2 is provided a liquid storage tank 11. At the top end of the I-shaped frame 1 on the side of the cleaning tank 2 away from the liquid storage tank 11 is provided a transmission frame 3. An electric motor 4 is installed on the outer wall of the transmission frame 3 away from the cleaning tank 2, and the output end of the electric motor 4 is installed with a rotating shaft 5 through a coupling;

[0026] During use, through the setting of the electric motor 4, the driving roller 6 can be driven to rotate through the rotating shaft 5;

[0027] The end of the rotating shaft 5 away from the electric motor 4 extends into the interior of the cleaning tank 2 and is provided with a driving roller 6. Inside the cleaning tank 2 on one side of the driving roller 6 is provided a driven roller 17. One end of the driven roller 17 extends to the outside of the cleaning tank 2 and is rotatably connected to the inner wall of the transmission frame 3;

[0028] During use, through the setting of the driving roller 6 and the driven roller 17, the ink roller of the printing machine can be driven to turn over;

[0029] At the center position of the top of the transmission frame 3 is provided an upright frame 7, and the top end of the upright frame 7 is connected to the bottom end of the L-shaped component seat 8;

[0030] During use, through the setting of the upright frame 7, the L-shaped component seat 8 can be supported and placed;

[0031] Above the transmission frame 3, there is an L-shaped component placement seat 8. At the top of the L-shaped component placement seat 8, there is a limit rail 9. On one side of the bottom of the limit rail 9, a movable seat 18 is slidably connected. On the outer wall of one side of the L-shaped component placement seat 8, a telescopic driving member 10 is installed. One end of the telescopic driving member 10 is connected to the outer wall of the movable seat 18. At the bottom end of the movable seat 18, there is a bearing frame 19.
