Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A cleaning device for the stamping cylinder of a tinplate printing machine, such as Figures 1-3 As shown, the system includes a support frame 1, a cleaning box 2, a first motor 3, a lead screw 4, a guide rod 5, a slider 6, an impression roller 7, a second motor 8, a gear 9, a water sprayer 10, a third motor 11, a brush 12, and a wastewater pipe 13. The cleaning box 2 is connected to the upper right side of the support frame 1. The cleaning box 2 is made of transparent material for easy observation of the cleaning process. The lower part of the cleaning box 2 is sloped to facilitate wastewater collection and discharge. The first motor 3 is connected to the upper right side of the cleaning box 2. The output shaft of the first motor 3 passes through the cleaning box 2 and is connected to the lead screw 4. The lead screw 4 is rotatably connected to the support frame 1. A guide rod 5 connects the upper parts of the support frame 1 and the cleaning box 2. The guide rod 5 is slidably connected to two sliders 6 on the left and right. The right slider 6 is connected to the lead screw 4 by a thread. The lower part of the slider 6 is rotatably connected to the impression cylinder 7. The lower front part of the right slider 6 is connected to the second motor 8.
