[0030] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 7 A printing plate cleaning device includes a bracket 1, two support brackets are symmetrically arranged, and a rotating and translating cleaning component 2 for rotating and translating to comprehensively clean the printing plate is installed between the tops of the two brackets 1; the rotating and translating cleaning component 2 includes a translating fixed component 21 and a rotating cleaning component 22, the translating fixed component 21 is installed between the tops of the two brackets 1, and the rotating cleaning component 22 is installed at the bottom of the translating fixed component 21; a printing plate placing component 3 for supporting the lifting of the printing plate is provided between the bottoms of the two brackets 1.

[0032] When the utility model is used, when the printing plate needs to be cleaned, the printing plate placed on the printing plate placing component 3 rises, and the rotating cleaning component 22 performs cyclic rotating cleaning. After cleaning a part of the printing plate, the translation fixing component 21 drives the rotating cleaning component 22 to translate to the right for the next rotation cleaning, until the right side of the printing plate is cleaned, thereby achieving comprehensive cleaning of the printing plate.

[0033] In the embodiment, the translation fixing assembly 21 includes a support frame 211, a screw rod 212, a motor 213, a slider 214, a connecting plate 215, a block 216 and a spring 217. The support frame 211 is fixedly installed between the tops of the two brackets 1, the screw rod 212 is arranged inside the support frame 211 for rotation connection, the left end of the screw rod 212 is fixedly connected to the output end of the motor 213, the motor 213 is fixedly installed inside the left end of the support frame 211, the top of the slider 214 is threadedly connected to the screw rod 212, and the slider 214 is connected to the support frame 211. The bottom of the supporting frame 211 is slidably connected, and the block 216 is set in the internal sliding connection of the slider 214. The top of the block 216 can slide and fit on the bottom of the support frame 211. The top of the connecting plate 215 is provided with a slot that matches the bottom sliding connection of the block 216. The top of the spring 217 is fixedly connected to the bottom of the block 216, and the bottom of the spring 217 is fixedly connected to the inner bottom wall of the slot of the connecting plate 215. The inner wall of the slot of the connecting plate 215 is fixedly installed on the bottom outer wall of the slider 214, and the bottom of the connecting plate 215 is connected to the rotating cleaning component 22.

[0034] Among them, four equally spaced wedge-shaped grooves are opened at the bottom of the support frame 211, and the grooves can be engaged with the top of the block 216; the left and right sides of the top of the block 216 are set as arc-shaped surfaces, and the arc-shaped surface setting facilitates the top of the block 216 to slide out of the groove.

[0035] When the present invention is in use, when cleaning shift is required, motor 1 213 drives screw rod 212 to rotate, screw rod 212 drives slider 214 to move right, slider 214 drives block 216 to move right, and the top of block 216 slides out of the groove of support frame 211. At this time, block 216 moves down, squeezing spring 217, block 216 drives connecting plate 215 to move right, and connecting plate 215 drives rotary cleaning assembly 22 to move right; when block 216 reaches the next groove of support frame 211, spring 217 rebounds, drives block 216 to rise, and the top of block 216 is inserted into the groove of support frame 211 and stuck. At this time, motor 1 213 is turned off, and rotary cleaning assembly 22 starts working, thereby realizing the fixed-point cleaning operation of the surface of the printing plate at the groove position of support frame 211.

[0036] In the embodiment, the rotary cleaning assembly 22 includes a second motor 221, a ring plate 222, a connecting rod 223, a cross plate 224, and a cleaning brush 225. The second motor 221 is fixedly mounted on the bottom of the connecting plate 215. The output end of the second motor 221 is fixedly connected to the top of the connecting rod 223. The ring plate 222 is rotatably mounted on the outside of the connecting rod 223. The bottom of the connecting rod 223 is fixedly connected to the top surface of the cross plate 224. The bottom surface of the ring plate 222 is in contact with the top surface of the cross plate 224 and is rotatably connected. The cleaning brush 225 is fixedly mounted on the bottom of the cross plate 224. The outer wall of the connecting rod 223 is provided with an annular groove, and the outer wall of the ring plate 222 is provided with a through opening. The spacing between two adjacent grooves on the support frame 211 is less than the length of the long side of the cross plate 224.

[0037] The rotary cleaning assembly 22 also includes a water trough 226 and a through-trough 227. The water trough 226 is formed inside the connecting rod 223, and the through-trough 227 is formed inside the cross plate 224 and the cleaning brush 225. The through-trough 227 connects the interiors of the cross plate 224 and the cleaning brush 225. One end of the water trough 226 connects to the outside of the annular groove of the connecting rod 223, and the other end of the water trough 226 connects to the through-trough 227. Six cleaning brushes 225 are provided and are evenly spaced at the bottom of the cross plate 224.

[0038] During use of the present invention, when reciprocating cleaning is required, the top of the clamping block 216 engages with the groove on the support frame 211, and the second motor 221 drives the connecting rod 223 to rotate, which in turn drives the horizontal plate 224 to rotate, which in turn drives the cleaning brush 225 to rotate, thereby performing a cyclical cleaning of the printed plate. Simultaneously, the opening of the ring plate 222 is connected to an external pipeline, allowing the inflow of detergent and water. The water flows from the water trough 226 into the through groove 227 and is ultimately ejected from the bottom of the through groove 227 of the cleaning brush 225 to clean the surface of the printed plate. Because the spacing between two adjacent grooves on the support frame 211 is less than the length of the long side of the horizontal plate 224, the rotating circular ranges of the horizontal plates 224 at the two adjacent grooves overlap, and the diameter of the overlapping portion is greater than the width of the printed plate, allowing for more thorough cleaning.

[0039] In the embodiment, the printed board placement assembly 3 includes a support plate 31, a cylinder 32 and a support plate 33. The two cylinders 32 are respectively arranged on both sides between the bottoms of the two brackets 1. The output ends of the two cylinders 32 are fixedly connected to the support plate 31. The tops of the two support plates 31 are used to place the printed board, and the sides of the two cylinders 32 facing away from each other are fixedly connected to the support plates 33.

[0040] When the utility model is used, when the printing plate needs to be cleaned and placed, the two support plates 31 can support and fix the printing plate, and the cylinder 32 drives the support plate 31 to move upward to correspond to the cleaning surface of the cleaning brush 225 for easy brushing.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
