Embodiment 1
[0074] Such as figure 1 As shown, a cleaning device for cleaning the rubber cylinder of a printing press includes: two wallboards 1 arranged symmetrically, a cloth shaft 2 and a cleaning cloth roll 4, wherein the cloth shaft 2 is rotatably connected to the two wallboards 1, The cleaning cloth roll 4 is wound on the cloth shaft 2 . The wall panel 1 provides support for the cloth shaft 2 and other components.
[0075] Such as figure 1 As shown, the cloth amount detection mechanism 3 of the blanket cylinder of the printing press is arranged on one of the wallboards 1. Specifically, the cloth amount detection mechanism 3 of the blanket cylinder of the printing press includes a rotating shaft 33, a cloth inspection rocker arm 31 and a cloth inspection sensor 39, wherein , the rotating shaft 33 passes through the above-mentioned wallboard 1, the rotating shaft 33 is rotatably connected with the wallboard 1, one end of the cloth inspection rocker arm 31 is connected with the rotati...
Embodiment 2
[0087] The difference between embodiment 2 and embodiment 1 is that, as Figure 6 As shown, the cloth inspection sensor 39 adopts a displacement sensor 39b, one end of the displacement sensor 39b is pivotally connected to the wallboard 1, and the other end is pivotally connected to the detection block 34.
[0088] As preferred, such as Figure 8 As shown, the cleaning device also includes a processor 5 and a display 6, the processor 5 is configured to receive the cloth amount signal generated by the cloth inspection sensor 39; the processor 5 is connected to the display 6, and the processor 5 is configured to be able to The signal calculates the remaining cloth amount, and the display 6 is set to be able to display the remaining cloth amount.
[0089] As preferred, such as Figure 8 As shown, the cleaning device also includes an alarm 7. When the cloth amount signal reaches a preset value, the processor 5 sends an alarm signal to the alarm 7, and the alarm 7 is set to alarm ...
Embodiment 3
[0091] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 2 is that the deployment detection sensor 39 in this embodiment adopts an angle sensor 39c, and the angle sensor 39c is directly connected to the rotating shaft 33 for measuring the twisting angle of the rotating shaft 33.
[0092] in, Figure 10 The embodiment of and embodiment 1, embodiment 2, and embodiment 4 are combined in the case where there is no contradiction.
[0093] Further, the cleaning cloth derived from the cleaning cloth roll is wrapped on the pressure head (rubber strip), and in the cleaning process, the rubber strip is compressed by the pressure of the rubber cylinder; the cleaning method also includes step E: Make a relationship curve between the pressure between the rubber strip and the rubber cylinder and the compression amount in advance, and determine a reasonable compression value on the relationship curve according to the degree of cleaning and the rotation speed ...
