[0002] The double-sided detection device of the gravure printing machine is an important equipment used on the gravure printing machine. Its main function is to ensure the quality of double-sided printing during the printing process. It mainly captures and records the image information in the printing process through the camera group on the double-sided detection device of the gravure printing machine. The camera group can capture the image of the printed product and provide real-time feedback on the printing quality of the printed product, such as color, clarity, image and text integrity, etc. The working environment of the double-sided detection device of the gravure printing machine is relatively complex. A large amount of printing coatings are stored during the printing process, and the printing coatings will splash through the gravure printing machine.

[0003] Most of the existing double-sided inspection devices of gravure printing machines lack protective devices on the lens of the camera group when in use. As a result, in a complex working environment, the lens is easily covered with dust, impurities and splashed printing paint, which leads to poor image quality and inaccurate information captured by the camera group, making it difficult to control the quality of the printed products. In addition, it is time-consuming and laborious to clean the lens, especially the cleaning of the printed paint on the lens requires the use of cleaning agents, which are difficult to remove by ordinary wiping.

[0004] Therefore, a double-sided detection device for a gravure printing machine is proposed. Utility Model Content

[0027] like Figures 1 to 6 As shown, a specific embodiment of the utility model provides a double-sided detection device for a gravure printing machine, comprising a gravure printing machine 1, a detection device 2 fixedly mounted on the top of the gravure printing machine 1, and a camera 3 arranged on the top of the detection device 2. A protective plate 4 is arranged at the bottom of the lens of the camera 3. The protective plate 4 is made of a transparent glass material, which is convenient for the camera 3 to capture information through the protective plate 4. By setting the protective plate 4, the lens of the camera 3 can be protected to prevent external dust and impurities and paint from splashing onto the lens surface and affecting the camera 3 from capturing information. A cleaning component for wiping paint dust on the surface of the protective plate 4 is arranged at the bottom of the protective plate 4. By setting the cleaning component, it is convenient to clean and remove dust and paint and other contaminants on the surface of the protective plate 4. Dyes are ensured to ensure that the camera 3 continues to work normally through a clean protective plate 4. The cleaning component includes a movable frame 5 arranged in the detection device 2, and a limit box 6 is fixedly connected to the movable frame 5. A solution box 7 is arranged in the limit box 6, and a cleaning cotton 8 is arranged in the solution box 7. It also includes a switch component arranged at the bottom of the detection device 2 for automatically providing a wiping agent to the cleaning cotton 8. By setting the switch component, it is convenient to provide the cleaning cotton 8 with a reagent for wiping the paint at a regular time, so that the staff does not need to spend time and effort to spray the reagent on the cleaning cotton 8. The switch component includes a push plate 9 slidably connected to the solution box 7. A push block 10 is arranged at the bottom of the detection device 2, and a stop block 11 is arranged on one side of the push block 10.

[0028] like Figure 2 , Figure 4 and Figure 5As shown, specifically, a liquid storage tank 12 is fixedly installed on the top of the movable frame 5, and the liquid storage tank 12 stores reagents for wiping the paint, and a drainage pipe 13 with a sealed top is provided at the bottom end of the liquid storage tank 12, and a connecting pipe 14 is slidably connected to the inner cavity of the drainage pipe 13, and the other end of the connecting pipe 14 passes through the inner cavity of the solution box 7, and a motor 20 is fixedly installed on one side of the detection device 2, and a threaded rod 21 is fixedly connected to the output shaft of the motor 20, and the threaded rod 21 is threadedly connected to the movable frame 5, and the threaded rod 21 is rotatably connected to the detection device 2. When paint or foreign matter is found on the protective plate 4 in the information results captured by the camera 3, the motor 20 is started to drive the threaded rod 21 to rotate, and the threaded rod 21 enables the movable frame 5 to move with the limit box 6 and the solution box 7 at the bottom end of the protective plate 4, and the solution The cleaning cotton 8 in the box 7 wipes the protective plate 4 during the movement, and a frame 17 is fixedly connected between the bottom end of the push plate 9 and the drain pipe 13, and the push block 10 is fixedly installed on the frame 17, and a first spring 18 is fixedly connected between the push block 10 and the moving frame 5, and a support plate 19 is fixedly connected to the bottom end of the detection device 2, and the stopper 11 is fixedly installed on the support plate 19. When the moving frame 5 moves, it drives the liquid storage tank 12 and the frame 17 at the top to move. When the push block 10 on the frame 17 moves to the stopper 11 on the support plate 19 and applies pressure to the stopper 11, one side of the stopper 11 is inclined at the same angle as one side of the push block 10, thereby causing the frame 17 to move upward. At this time, the first spring 18 is forced to contract, and the frame 17 moves upward to push the push plate 9 and the drain pipe 13 upward.

[0029] like Figure 5 and Figure 6 As shown, specifically, a limiting hole 15 is provided in the liquid storage tank 12, and a through hole 16 connected to the inside is provided on the drainage pipe 13. When the drainage pipe 13 moves upward, the through hole 16 disengages from the limiting hole 15 and moves into the inner cavity of the liquid storage tank 12. At this time, the reagent in the liquid storage tank 12 can be discharged to the connecting pipe 14 through the through hole 16, and then discharged to the inner cavity of the solution box 7. At the same time, the push plate 9 moves upward to push the reagent flowing into the solution box 7 to contact with the cleaning cotton 8, so that the absorbent cleaning cotton 8 absorbs the reagent, and then the combination of the reagent and the cleaning cotton 8 facilitates the cleaning of the paint on the protective plate 4 during movement. After the push block 10 disengages from the block 11 during the movement, the frame 17 moves downward and resets under the gravity of the push plate 9 and the reaction force of the first spring 18. At this time, the frame 17 drives the drainage pipe 13 to move downward and reset, so that the through hole 16 is re-engaged into the limiting hole 15, so that the reagent in the liquid storage tank 12 cannot continue to enter the solution box 7.

[0030] like Figure 5As shown, specifically, a second spring 23 is fixedly connected between the movable frame 5 and the solution box 7. By arranging the second spring 23, the solution box 7 pushes the solution box 7 and the cleaning cotton 8 to always be in contact and friction with the protective plate 4 under its reaction force, thereby increasing the pressure and facilitating cleaning and wiping. Connecting plates are fixedly connected to both sides of the solution box 7, and wiping cotton 24 is arranged on the connecting plates. By arranging the wiping cotton 24, the protective plate 4 can be further wiped by the wiping cotton 8 stained with the reagent after being wiped, thereby enhancing the cleaning effect. When the moving frame 5 moves to the second stop block 11 or reverse drives the motor 20, its working principle is the same as described above. The protective plate 4 is wiped multiple times by repeatedly driving the motor 20 to remove impurities or paint on the surface of the protective plate 4, thereby ensuring that the camera 3 can work normally to capture information. A limit groove is provided in the detection device 2, and a limit frame 22 is slidably connected in the limit groove, and the protective plate 4 is arranged in the limit frame 22. By setting the limit frame 22, when the protective plate 4 is damaged, the limit frame 22 in the limit groove is pulled to take out the protective plate 4 for replacement.
