[0029] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0030] This specific embodiment relates to a cleaning device for a cylinder screen 200. Figure 1 As shown, it includes a bracket 100. A rotatable round net 200 is arranged on the bracket 100. The round net 200 is a cylindrical screen, and the round net 200 is engraved with meshes with patterns. The round net 200 is rotatably connected to the bracket 100 through a roller skating assembly, so that the round net 200 can be cleaned while rotating. The roller skating assembly includes a driving wheel 500 and a driven wheel 510 respectively arranged on both sides of the round net 200, and the driving wheel 500 and the driven wheel 510 are both against the round net 200 and arranged on the bracket 100. The roller skating assembly is located below the round net 200. When the round net 200 is installed on the bracket 100, the roller skating assembly can support the round net 200. The round net 200 is also easy to install and disassemble. The driving wheel 500 is rotated by a motor, and then the rotation of the driving wheel 500 drives the rotation of the round net 200, and the rotation of the round net 200 drives the rotation of the driven wheel 510. The driven wheel 510 cooperates with the driving wheel 500 to correct the cylinder 200. At least two groups of roller skating assemblies are provided and are respectively located at both ends of the cylinder 200 along its axial direction. The two groups of roller skating assemblies can make the cylinder 200 more stable during the rotation process. The number of roller skating assemblies can also be increased according to the actual production needs.

[0031] like Figures 1 to 8As shown, a water spray assembly 300 is arranged on the bracket 100 and can move axially along the round screen 200. When the printing work of the round screen 200 is completed, the round screen 200 will be removed from the round screen 200 printing machine and then installed in the bracket 100. After the installation is completed, the water spray assembly 300 starts to work. The water spray assembly 300 removes stains on the round screen 200 and the magnetic suction member by spraying water. The water spray assembly 300 is located above the magnetic suction member. The water spray assembly 300 includes a cleaning head 310 and at least two nozzles 320. The cleaning head 310 reciprocates through a first driving member. The first driving member can be a cylinder. The cleaning head 310 is arranged on the driving shaft of the first driving member, and then reciprocates and retracts along the radial direction of the round screen 200 through the first driving member, so that the water sprayed from the cleaning head 310 can cover most areas of the round screen 200. At least two nozzles 320 are arranged on both sides of the cleaning head 310. At least two nozzles 320 are arranged at intervals on each side, and the nozzles 320 are connected to a water pipe, and the other end of the water pipe is connected to a water tank and drives water to flow through a driving device, which can be a water pump. At least one nozzle 320 is arranged at the front end of the cleaning head 310. There are two nozzles 320 arranged at the front end and they are arranged at intervals.

[0032] like Figures 1 to 3 , Figures 6 to 8 As shown, the bracket 100 is also provided with a brush assembly 400 that can cooperate with the water spray assembly 300, and the brush assembly 400 is used to brush away impurities on the round screen 200. The water spray assembly 300 and the brush assembly 400 are both located inside the round screen 200. After printing is completed, the water spray assembly 300 first extends through the first driving member, and then moves along the magnetic suction member while spraying water through the nozzle 320. The brush assembly 400 is located below the water spray assembly 300. When the round screen 200 is wetted with water, the round screen 200 will continue to rotate, and the brush assembly 400 will brush away the dirt on the round screen 200. The brush assembly 400 includes bristles 410, which are reciprocated by the second driving member. After the water sprayed by the nozzle 320 falls on the round screen 200, the bristles 410 are used to remove impurities on the round screen 200. The brush assembly 400 includes a connector 420 connected to the driving end of the second driving member, and the connector 420 is a bristle 410. The bristles 410 are arranged on the side wall of the connector 420. The brush assembly 400 can also be installed on a linear motor module. The brush assembly 400 can also rotate while moving in the round net 200 through the linear motor module to better remove the stains in the round net 200. The bristles 410 are evenly distributed on the side wall or the peripheral wall of the connector 420. During the rotation of the connector 420, the impurities on the round net 200 can be removed by brushing the bristles 410. The rotation direction of the connector 420 is opposite to the rotation direction of the round net 200.

[0033] like Figures 2 to 5As shown, a drying unit 600 is provided between the support 100 and the round net 200 for drying the round net 200 after cleaning. The drying unit 600 is used for quick drying of the round net 200 to prevent the round net 200 from rusting in a humid condition. The drying unit 600 includes a fan and an air outlet 610 connected to the fan, and the fan is located below the support 100 and is generally fixed on the ground. The air outlet end of the air outlet 610 faces the round net 200. The air outlet 610 is provided on the support 100 and is located on the support 100 for spacing the round net 200. The air outlet 610 is provided at intervals, and the air outlet end faces the round net 200, so as to dry and remove the cleaning liquid on the surface of the round net 200.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
