Description

Technical Field

[0001] The utility model belongs to the technical field of PS plate sealing holes, and particularly relates to a sealing hole device for PS plate production. Background Technique

[0002] A PS plate refers to a pre-coated photosensitive plate for printing in which a photosensitive resin is coated on a hydrophilic anodized aluminum plate substrate. After the aluminum plate serving as the PS plate base is anodized, a porous oxide film is formed on the surface. This oxide film has very strong adsorption. When directly coating a photosensitive layer on it, the photosensitive layer will penetrate into the pores of the oxide film and be firmly adsorbed and not easily removed. By performing a sealing hole treatment on the surface of the anodized aluminum plate, the adsorption force of the oxide film on the photosensitive layer can be reduced. By sealing the holes, a good hydrophilic surface can be formed. After sealing the holes, the alkali resistance and wear resistance of the oxide film are improved. After the alkali resistance of the oxide film is improved, the dissolution of the oxide film in the developer can be effectively reduced during the development process of the PS plate, increasing the service life of the developer and the printing resistance of the printing plate;

[0026] Furthermore:

[0027] As Figures 1-3 shown:

[0028] A cleaning component 4 is installed on the surface of the sealing chamber main body 1. The cleaning component 4 includes side plates 407 that are symmetrically arranged and fixed on one side of the sealing chamber main body 1, a first conveying roller 402 that is symmetrically arranged and rotatably connected between the two groups of side plates 407 through bearings, and a first gear 403 fixed at one end of the first conveying roller 402.

[0031] In this embodiment: When the sealing device for PS plate production is in use and the sealing liquid seals the aluminum plate body 3, by starting the driving motor 401, the first conveying roller 402 is driven to rotate. By driving a set of first gears 403 to rotate, since the two sets of first gears 403 are meshed and connected, the other set of first gears 403 is driven to rotate, so that the two first conveying rollers 402 can be driven to rotate relatively, thereby conveying the aluminum plate body 3. At the same time, the first sprocket 404 is driven to rotate. Since the first sprocket 404 is meshed and connected with the second sprocket 406 through the chain 405, the second sprocket 406 is driven to rotate. The second conveying roller 419 is driven to rotate by the second sprocket 406. The second gear 408 is driven to rotate by the second conveying roller 419. Since the second gear 408 and the third gear 409 are meshed and connected, the third gear 409 is driven to rotate. The cleaning brush 410 is driven to rotate by the third gear 409. The impurities on the surface of the aluminum plate body 3 are cleaned by the cleaning brush 410, so as to avoid the unevenness of the plate surface that may be caused by impurities on the aluminum plate body 3, which will not affect the uniform coverage of the sealing liquid and the sealing effect. At the same time, it avoids polluting the sealing liquid and will not cause the loss of some details and clarity of the plate surface due to the blockage of the micro-pores on the aluminum plate body 3, improves the quality and use effect of the printed matter, further meets the actual use requirements. Through the setting of the second conveying roller 419, it not only supports the aluminum plate body 3, but also conveys the aluminum plate body 3.

[0032] Furthermore;

[0033] In an alternative embodiment, a rotating disk 411 is fixed to the other end of the cleaning brush 410. The surface of the rotating disk 411 is hinged with a first movable rod 412 through a hinge shaft. A pin body is fixed to the other end of the first movable rod 412. A square block is fixed to one side of the side plate 407 close to the first movable rod 412. A second movable rod 413 is slidably connected in the square block. A rectangular hole is opened at the top of the outer side of the second movable rod 413. The pin body is rotatably installed in the rectangular hole through a bearing. A piston disk 415 is fixed to the bottom end of the second movable rod 413. An air supply cylinder 414 is arranged outside the piston disk 415. The air supply cylinder 414 is fixedly connected with the side plate 407. The bottom end of the air supply cylinder 414 is fixedly communicated with an exhaust pipe 418. One end of the exhaust pipe 418 penetrates through a set of side plates 407 and is fixedly connected with the other set of side plates 407. A one-way intake valve 417 is fixedly installed at the bottom of the air supply cylinder 414. A plurality of equally spaced air nozzles are installed on the surface of the exhaust pipe 418;

[0034] A sliding groove adapted to the second movable rod 413 is opened on the surface of the square block. The second movable rod 413 and the square block are slidably connected through the sliding groove.

[0035] In this embodiment: As the cleaning brush 410 rotates, it drives the rotating disk 411 to rotate. The rotating disk 411 drives the first movable rod 412 to rotate, causing the pin on the first movable rod 412 to rotate within the rectangular hole of the second movable rod 413, thereby driving the second movable rod 413 to reciprocate. The second movable rod 413 drives the piston disk 415 to reciprocate up and down inside the air supply cylinder 414. The piston disk 415 compresses the air inside the air supply cylinder 414 into the exhaust pipe 418, and the air is discharged through the air nozzle on the exhaust pipe 418. The blown air can further remove the dust and other impurities remaining on the surface of the aluminum plate body 3 after being cleaned by the cleaning brush 410. The combined use of the cleaning brush 410 and the blown air can accelerate the cleaning speed. Compared with using only the cleaning brush 410 or the blown air alone, the cleaning work can be completed more quickly, further improving the usage effect of the device. When the piston disk 415 moves upward, it can achieve an air intake effect through the one-way intake valve 417.

[0036] Furthermore;

[0037] In an alternative embodiment, a sealing ring 416 is fixed to the outer surface of the piston disk 415, and the sealing ring 416 is in contact with the inner side wall of the air supply cylinder 414.

[0038] In this embodiment: While the piston disk 415 moves, due to the arrangement of the sealing ring 416, its sealing performance can be enhanced, preventing air leakage and improving the exhaust effect.

[0039] Working principle and usage process of the present utility model: When using the hole-sealing device for PS plate production, when the hole-sealing liquid seals the aluminum plate body 3, by starting the driving motor 401, the conveying roller 402 is driven to rotate. By driving a set of gears 403 to rotate, since the two sets of gears 403 are meshed and connected, another set of gears 403 is driven to rotate, so that the two sets of conveying rollers 402 can be driven to rotate relatively, thereby conveying the aluminum plate body 3. At the same time, the sprocket 404 is driven to rotate. Since the sprocket 404 is meshed and connected with the sprocket 406 through the chain 405, the sprocket 406 is driven to rotate. The conveying roller 419 is driven to rotate by the sprocket 406. The gear 408 is driven to rotate by the conveying roller 419. Since the gear 408 and the gear 409 are meshed and connected, the gear 409 is driven to rotate. The cleaning brush 410 is driven to rotate by the gear 409. The impurities on the surface of the aluminum plate body 3 are cleaned by the cleaning brush 410, so as to avoid the unevenness of the plate surface caused by impurities on the aluminum plate body 3, which will not affect the uniform coverage of the hole-sealing liquid and the hole-sealing effect. At the same time, it avoids polluting the hole-sealing liquid and will not cause the loss of some details and clarity of the plate surface due to the blockage of the micro-pores on the aluminum plate body 3, improving the quality and usage effect of the printed matter, further meeting the actual usage requirements. Through the setting of the conveying roller 419, it not only supports the aluminum plate body 3, but also conveys the aluminum plate body 3. As the cleaning brush 410 rotates, the rotating disk 411 is driven to rotate. The movable rod 412 is driven to rotate by the rotating disk 411, so that the pin on the movable rod 412 rotates in the rectangular hole of the movable rod 413, thereby driving the movable rod 413 to reciprocate. The piston disk 415 is driven to reciprocate up and down inside the air supply cylinder 414 by the movable rod 413. The air inside the air supply cylinder 414 is compressed into the exhaust pipe 418 by the piston disk 415 and discharged through the air nozzle on the exhaust pipe 418. The blowing of the gas can further remove the dust and other impurities remaining on the surface of the aluminum plate body 3 after being cleaned by the cleaning brush 410. The combined use of the cleaning brush 410 and the blowing of the gas can accelerate the cleaning speed. Compared with using the cleaning brush 410 or the blowing of the gas alone, the cleaning work can be completed more quickly, further improving the usage effect of the device. When the piston disk 415 moves upward, the air intake effect can be achieved through the one-way air intake valve 417. While the piston disk 415 moves, through the setting of the sealing ring 416, its sealing performance can be increased, avoiding gas leakage and improving the exhaust effect.
