[0023] The clamping assembly includes a housing 23 mounted at the end of a connecting rod 22, an electric telescopic rod 24 is arranged in the housing 23, and an output shaft of the electric telescopic rod 24 passes through the housing 23 and is connected to a clamping plate 25;

[0024] A cleaning component is provided in the cleaning tank 12 .

[0025] In the initial state, the two clamping plates 25 are far away from each other and are located at the upper end of the processing tank 1; when in use, the hollow gravure cylinder is placed between the two clamping plates 25, and then the electric telescopic rod 24 is started to drive the clamping plate 25 to approach the hollow gravure cylinder to clamp the two ends of the hollow gravure cylinder; the motor 21 is started to drive the rotating shaft 2 to rotate, and then the hollow gravure cylinder can be driven into the electroplating liquid in the electroplating tank 13 through the connecting rod 22, and the electroplating treatment is performed in the electroplating tank 13. After the electroplating is completed, the motor 21 can be started to drive the hollow gravure cylinder into the cleaning tank 12, and the cleaning component in the cleaning tank 12 will rinse the hollow gravure cylinder to rinse off the residual electroplating liquid on its surface, so as to facilitate subsequent processing;

[0026] Through the arrangement of the electric telescopic rod 24 and the clamping plate 25, hollow gravure cylinders of different models can be clamped and fixed;

[0027] The housing 23 protects the electric telescopic rod 24 to prevent the electric telescopic rod 24 from being damaged by prolonged contact with the electroplating solution.

[0028] The housing 23 is rotated at the end of the connecting rod 22 through a rotating rod;

[0029] The cleaning assembly includes a water storage tank 3 installed at the front side of the processing pool 1, a water pump is arranged in the water storage tank 3, the water outlet end of the water pump is connected to a water outlet pipe 31, the end of the water outlet pipe 31 is connected to a nozzle 311 located in the cleaning pool 12, a circular shell 32 is installed at the front side of the processing pool 1, the water outlet pipe 31 is connected to one side of the circular shell 32, a rotating block 33 is rotatably arranged in the middle of the circular shell 32, a plurality of evenly distributed push plates 34 are installed on the side of the rotating block 33, the rear end of the rotating block 33 extends into the cleaning pool 12 and is connected to a first gear 35, the front wall of the cleaning pool 12 is rotatably equipped with a second gear 36 meshing with the first gear 35, and a third gear 37 matching the second gear 36 is fixed to the end of the front rotating rod;

At this time, the second gear 36 connected to the end of the front rotating rod will mesh with the third gear 37. By starting the water pump in the water storage tank 3, the clean water in the water storage tank 3 enters the nozzle 311 through the outlet pipe 31, and is finally sprayed out from the several nozzles of the nozzle 311 to rinse the hollow gravure cylinder. When the clean water flows in the outlet pipe 31, the clean water will enter the circular shell 32, pushing the several push plates 34 to rotate, thereby driving the first gear 35 to rotate through the rotating gear 33, and then driving the second gear 36 to rotate, and the third gear 37 rotates, so that the hollow gravure cylinder itself rotates.

After the cleaning of the hollow gravure cylinder is completed, the staff can rotate the screw 4 to drive the strip plate 41 to approach the hollow gravure cylinder, so that the sponge bar 42 abuts against the surface of the hollow gravure cylinder, and then the staff can rotate the handle 43 to drive the second gear 36 to rotate, and then drive the hollow gravure cylinder to rotate, and the sponge bar 42 can be used to wipe off the water stains remaining on the surface of the hollow gravure cylinder.

[0033] Limit rods 44 are fixed on both the front and rear sides of the strip plate 41, and the limit rods 44 are slidably connected to the side walls of the cleaning tank 12; the limit rods 44 are slidably connected to the side walls of the cleaning tank 12, which can limit the strip plate 41 so that the strip plate 41 can only slide left and right.

[0034] The utility model can conveniently carry out electroplating on the hollow gravure printing cylinder, and after the electroplating is completed, it can be quickly transferred to the inside of the cleaning pool, and the water pressure can automatically drive the hollow gravure printing cylinder to rotate, so that the hollow gravure printing cylinder can be fully washed to avoid residual electroplating liquid on the surface of the hollow gravure printing cylinder, and the structural design is reasonable.
