Description

Technical Field

[0001] This utility model relates to the field of printing plate making equipment technology, specifically a sealing device for CTP plates that does not require processing. Background Technology

[0002] The development of computer-to-plate (CTP) technology has been rapid, especially with the increasing maturity and widespread adoption of thermal CTP plate-making technology. Developing high-performance CTP plates has become a focus of the printing plate manufacturing industry. Currently, commonly used thermal plates mainly include negative thermal cross-linking thermal CTP plates, positive thermal CTP plates, and thermal ablation thermal CTP plates. The CTP plate-making process requires a sealing treatment, which involves using chemical methods to treat the micropores of the oxide film on the surface of anodized aluminum plates to adjust their surface properties.

[0003] Existing sealing coating devices mostly employ a single coating structure, making it difficult to achieve uniform solution coating. This can easily lead to inconsistent sealing effects on the plate surface, affecting printing quality. Furthermore, solutions are prone to waste during coating, making effective recycling impossible and increasing production costs. After sealing, the plates lack efficient drying and cleaning processes. Traditional drying equipment often suffers from low drying efficiency and uneven temperature, easily leaving residual moisture on the plate surface, affecting subsequent use. The absence of a cleaning step allows impurities on the plate surface to affect the sealing effect, reducing the plate yield. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this embodiment proposes a CTP plate sealing device without processing. The CTP plate sealing device includes: a main unit 1, with mounting plates 101 fixedly connected to the left and right sides of the inner wall of the main unit 1. A first rotating shaft 102 is movably connected inside the mounting plate 101, and a conveyor belt 103 is movably connected to the outer wall of the first rotating shaft 102. A first meshing gear 104 is fixedly connected to the outer wall of the left end of the first rotating shaft 102. The CTP plate is placed on the placement plate 1011 of the conveyor belt 103. The drive motor 1010 drives the drive box 109 to rotate, thereby driving the first rotating shaft 102 to rotate, so that the conveyor belt 103 starts to transport the plate. During the transport process, the first meshing gear 104 at the left end of the first rotating shaft 102 drives the second meshing gear 106 to rotate through the chain 107, so that the second rotating shaft 105 rotates synchronously. The cleaning rod 108 fixed on the second rotating shaft 105 rotates accordingly to clean the surface of the plate and remove impurities.

[0023] The drying unit 2 has an internal mounting groove 201. A first air pump 202 is fixedly installed at the rear of the mounting groove 201. A first air rod 203 is movably connected to the output end of one side of the first air pump 202. Slide rails 204 are fixedly connected to the left and right sides of the upper surface of the main unit 1, and the slide rails 204 are located inside the mounting groove 201. The first air pump 202 pushes the first air rod 203, which drives the sliding frame 205 to move laterally along the slide rails 204 on the upper surface of the main unit 1, adjusting the position of the hot air box 2011 so that it is aligned with the plate.

[0024] The sealing unit 3 has a servo motor 301 fixedly connected to the middle of its left side and a solution conduit 302 fixedly connected to its right side. A circulation pipe 303 is provided on one side of the solution conduit 302. The output end of the servo motor 301 is fixedly connected to a rotating shaft 304 via a coupling.

[0025] The scraping unit 4 has a first return spring 401 movably connected to the rear side of its inner wall, and second return springs 402 movably connected to the upper and lower sides of its interior.

[0026] Preferably, a second rotating shaft 105 is rotatably mounted on the left side of the main body unit 1, near the first meshing gear 104. A second meshing gear 106 is rotatably mounted on the outer wall of the second rotating shaft 105.

A solution tank 1012 is fixedly connected to one side of the main body unit 1 on the placement plate 1011. When the first rotating shaft 102 rotates, the first meshing gear 104 fixedly connected to the outer wall of its left end rotates accordingly. The first meshing gear 104 is connected to the second meshing gear 106 on the outer wall of the second rotating shaft 105 through the chain 107. When the first meshing gear 104 rotates, it drives the second meshing gear 106 to rotate through the chain 107, thereby causing the second rotating shaft 105 to rotate synchronously, thereby causing the cleaning rod 108 to rotate, so that the cleaning rod 108 can remove dust and impurities that may exist on the surface of the plate.

[0027] Preferably, a sliding frame 205 is slidably connected to the outer wall of the upper surface of the slide rail 204, and the sliding frame 205 is fixedly connected to the output end of the first air rod 203. A fixing plate 206 is provided inside the sliding frame 205. A second air pump 207 is fixedly connected to the upper surface of the fixing plate 206. A second air rod 208 is movably connected to the output end of the lower surface of the second air pump 207. Guide rods 209 are fixedly connected to the left and right sides of the lower surface of the fixing plate 206. A wind cutter plate 2010 is fixedly connected to the output end of the lower surface of the second air rod 208, and the wind cutter plate 2010 is slidably connected to the outer wall of the guide rod 209. A hot air box is fixedly connected to the upper surface of the wind cutter plate 2010. 2011, hot air box 2011 is fixedly connected to the left and right sides with air pipes 2012, and the first air pump 202 starts to drive the first air rod 203 to push the sliding frame 205 to move. The sliding frame 205 moves laterally along the slide rail 204 on the upper surface of the main unit 1, thereby adjusting the horizontal position of the hot air box 2011 so that it is accurately aligned with the plate. After the horizontal position is adjusted, the second air pump 207 drives the second air rod 208 to extend and retract, thereby causing the air cutting plate 2010 to slide up and down along the angle of the guide rod 209. Hot air is delivered to the air cutting plate 2010 through the air pipes 2012 on the left and right sides, and then blown out evenly by the air cutting plate 2010.

[0028] Preferably, an outer sleeve 305 is fixedly connected to the output end of one side of the rotating shaft 304. A plurality of sealing coating blocks 306 are fixedly connected to the outer wall of the outer sleeve 305. An inner core cylinder 307 is movably connected inside the outer sleeve 305. A solution passage cavity 308 is formed inside the inner core cylinder 307. A guide groove 309 is formed on the lower surface of the solution passage cavity 308. A flow divider block 3010 is connected to the inner wall of the guide groove 309. A guide pipe 3011 is formed between the outer sleeve 305 and the inner core cylinder 307, and the guide pipe 3011 is connected to the guide groove 309. Connecting shafts 3012 are movably connected to the left and right sides of the inner core cylinder 307. A servo motor 301 drives the rotating shaft 304 to rotate, and the output end of one side of the rotating shaft 304 is synchronized with the outer sleeve 305. The inner core cylinder 307 rotates, and the sealing solution flows into the solution passage 308 of the inner core cylinder 307 through the solution conduit 302. After the solution is collected in the solution passage 308, it is evenly distributed to the guide tube 3011 through the guide groove 309 and under the action of the diverter block 3010, so that the solution is stably delivered to the sealing coating block 306, thereby uniformly coating the solution on the surface of the CTP plate. The connecting shafts 3012 on the left and right sides of the inner core cylinder 307 can keep the inner core cylinder 307 vertically downward, and the connecting shafts 3012 rotate under the drive of the outer sleeve 305. The connecting shafts 3012 penetrate the interior of the inner core cylinder 307, and the connecting shafts 3012 rotate independently in the inner core cylinder 307, so that the guide groove 309 of the inner core cylinder 307 always faces downward.

[0029] In use, when the CTP plate is placed on the placement plate 1011 of the conveyor belt 103 of the main unit 1, the drive motor 1010 starts, and the power is transmitted to the first rotating shaft 102 through the drive box 109, driving the conveyor belt 103 to rotate and start the plate transmission. During the transmission process, the first meshing gear 104 at the left end of the first rotating shaft 102 drives the second rotating shaft 105 to rotate through the chain 107. The cleaning rod 108 fixed on the second rotating shaft 105 rotates synchronously to clean the surface of the plate and remove impurities. After cleaning, the plate is transmitted to the bottom of the sealing unit 3, and the servo motor 301 starts, driving the rotating shaft 304 to rotate through the coupling, thereby causing the outer sleeve 305 and the sealing coating block 306 to rotate at high speed. The sealing solution flows into the solution passage cavity 308 of the inner core cylinder 307 through the solution conduit 302, and is then evenly transported to the sealing coating block 306 through the guide groove 309, the diverter block 3010 and the guide pipe 3011. The rotating sealing coating block... 306 The solution is evenly applied to the surface of the plate to complete the sealing process. Excess solution flows back to the solution tank 1012 on the right side of the main unit 1 through the solution conduit 302 and circulation pipe 303. The sealed plate continues to move forward and enters the scraping unit 4. The first return spring 401 and the second return spring 402 in the scraping unit 4 keep the scraper 403 in close contact with the surface of the plate to scrape off the excess sealing solution. The scraped solution flows back to the solution tank 1012 through the inclined guide groove 404. Finally, the scraper... When the printing plate arrives at the drying unit 2, the first air pump 202 pushes the first air rod 203, which drives the sliding frame 205 to move laterally along the slide rail 204, adjusting the horizontal position of the hot air box 2011; the second air pump 207 drives the second air rod 208, which causes the air cutting plate 2010 to slide up and down along the guide rod 209, adjusting the vertical distance between the hot air box 2011 and the printing plate. After the adjustment is in place, hot air is delivered to the hot air box 2011 through the air pipe 2012 to quickly and evenly dry the surface of the printing plate.
