Description

Technical Field

[0001] This invention relates to the field of CTP plate production technology, and in particular to a double-sided coating and stepped drying equipment for high-print-resistant, heat-sensitive, double-coated CTP plates. Background Technology

[0002] CTP technology is one of the core technologies for the digital transformation of the printing industry. It adopts a digital workflow to directly convert text and images into digital signals and generate printing plates directly, eliminating the need for film materials, manual plate assembly, and exposure processes in traditional plate-making. CTP plates, as the core consumables of this technology, are mainly divided into photosensitive systems, thermal systems, and ultraviolet laser systems according to their plate-making principles. Among them, thermal CTP plates occupy a dominant position in the market due to their high printing durability, which can reach millions of printings.

[0003] In the manufacturing process of CTP plates, coating and drying are the key processes that determine the quality of the plates. The production of CTP plates usually includes processes such as degreasing of aluminum plates, electrolysis, descaling, oxidation, sealing, coating of photosensitive liquid, drying, cutting and packaging. For double-coated thermal CTP plates, the bottom layer coating and the top layer coating need to be completed sequentially on the aluminum plate base, and each coating needs to be dried.

[0004] Existing double-coating CTP plate coating and drying equipment suffers from defects such as uneven heating and the coating being prone to "skinning effect". The heating mechanism of traditional drying equipment is mostly a structure of radiant heating tube or radiant heating tube supplemented by axial flow fan, which easily generates obvious high temperature zone, resulting in uneven heating of the coating on the CTP plate and skinning phenomenon. In addition, existing drying equipment mostly adopts a constant temperature drying method with a single temperature range, which makes it difficult to finely control the drying temperature according to different stages of the coating drying process. Therefore, a double-sided coating stepped drying equipment for high printing resistance heat-sensitive double-coating CTP plates is proposed. Summary of the Invention

[0005] This invention addresses the problems of uneven drying of printing plates and surface dust residue affecting coating. It provides a double-sided coating stepped drying device for high-durability heat-sensitive double-coating CTP printing plates.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a double-sided coating stepped drying device for high-printability heat-sensitive double-coating CTP plates, including a support frame and a drying chamber; The drying chamber is equipped with a feeding rack and a unloading rack at both ends. The feeding rack and the unloading rack are installed at both ends of the drying chamber. A pre-treatment mechanism is installed on the feeding rack. The pre-treatment mechanism includes a transmission frame. A set of cleaning plates is installed inside the transmission frame. The cleaning plates are used to adhere to the outside of the printing plate to assist in cleaning. The unloading rack is equipped with a lifting plate, and a flipping mechanism for plate flipping is rotatably mounted on one side of the lifting plate. The flipping mechanism includes a rotating disk and a set of clamping plates. A vision inspection module is installed on the outside of the clamping plates. The vision inspection module is used for plate surface coating inspection. The pretreatment mechanism removes oil and dirt and recovers cleaning agents from the plate, effectively ensuring the surface cleanliness before coating. The positioning belt on the conveyor roller prevents the plate from shifting during transport, ensuring that it passes stably through the uniform drying area of ​​the stepped exhaust port. Combined with the movable discharge port of the coating mechanism, it achieves uniform material distribution, significantly improving the problems of coating skinning and uneven thickness. The lifting plate, rotating disk and clamping plates on the unloading rack enable the plate to flip smoothly, which is convenient for double-sided coating processing. At the same time, the vision inspection module performs multi-angle real-time detection on the coating surface during the flipping process, promptly identifying defects such as wrinkles and orange peel and providing feedback to adjust drying parameters, effectively improving product yield and process control accuracy.

[0007] A further preferred embodiment of the present invention is as follows: a sealing cover is installed on the top of the drying chamber, a conveying pipe is installed on the sealing cover, one end of the conveying pipe is connected to an air inlet device, a stepped exhaust port is installed at the bottom of the sealing cover, and several heating wires are installed inside the stepped exhaust port. The stepped exhaust port is connected to the conveying pipe. By using the stepped exhaust port in conjunction with the heating wires, gradient temperature rise drying is achieved, which can effectively avoid the coating from forming a skin due to sudden heating and significantly improve the drying uniformity.

[0008] A further preferred embodiment of the present invention is: a coating mechanism is installed at the bottom of the sealing cover plate, and a movable discharge port is provided at the bottom of the coating mechanism for coating the surface of the plate. The movable discharge port is used to move and coat the plate in close contact with it, so as to ensure that the material can be evenly distributed on the surface of the plate, thereby eliminating the processing quality defects caused by uneven coating.

[0009] A further preferred embodiment of the present invention is as follows: a set of connecting shafts is installed inside the drying chamber, and several transmission rollers are movably arranged between the connecting shafts. Several locking ring grooves are opened on the transmission rollers, and positioning belts are locked inside the locking ring grooves. The positioning belts are arranged outside the several transmission rollers and are used to abut against both ends of the printing plate. By using the locking ring grooves on the transmission rollers in conjunction with the adjustable positioning belts, the two ends of the printing plate are flexibly limited, effectively preventing the printing plate from deviating during the conveying process and ensuring that it is always in the optimal air-receiving position to improve drying efficiency.

[0010] A further preferred embodiment of the present invention is as follows: a plurality of rotating rollers are provided at the bottom of the feeding rack, and rubber sleeves are provided on the outside of the rotating rollers. A set of fixed seats is installed inside the feeding rack. A transmission plate is movably provided on the top of the fixed seats. A reset shaft insert is provided between the transmission plate and the fixed seats. An external threaded rod is installed on one side of the fixed seat and passes through the transmission plate. A control turntable is movably installed on the transmission plate. The control turntable is threaded onto the external threaded rod. A pressure roller is rotatably provided between the transmission plates. The distance between the pressure roller and the rotating roller is adjusted by the control turntable, so that the equipment can flexibly adapt to plates of different thicknesses and achieve stable pressing and smooth automated feeding.

[0011] A further preferred embodiment of the present invention is as follows: both ends of the cleaning plate are equipped with extension plates, and the bottom of the extension plates are connected to telescopic end blocks. The telescopic end blocks are movably inserted into the transmission frame. The transmission frame is provided with two sets of sliders, and the sliders are installed at one end of the extension plates. Straight grooves are provided on both sides of the cleaning plate, and a drive shaft is rotatably provided inside one straight groove. The drive shaft passes through the cleaning plate and is equipped with a connecting rod. A set of inclined plates is movably provided between the connecting rods, and a swing shaft is movably hinged inside the inclined plates. A rotating shaft is installed at the top of the swing shaft, and a hinge frame is installed on the rotating shaft. A hinge assembly is movably provided inside the hinge frame, and a tension tube is movably clamped at both ends on the other side. The tension tube is connected to the hinge assembly, and the tension tube is reciprocated at both ends of the straight groove by means of the rotation of the drive shaft. The drive shaft is externally fitted with several rubber sleeves, which abut against the surface of the printing plate. The friction of the advancing printing plate drives the drive shaft to rotate. The rotational motion is converted into the reciprocating oscillation of the stretching tube through a mechanical linkage mechanism, thus achieving the driving of physical cleaning action without the need for an additional power source.

[0012] A further preferred embodiment of the present invention is as follows: a telescopic rod is installed inside the stretching tube, and a cleaning frame is separately installed on the stretching tube. The cleaning frame consists of several fixed shafts and cleaning rings, with the fixed shafts installed outside the stretching tube and the cleaning rings evenly distributed on the fixed shafts. The cleaning frame is used to clean the surface of the printing plate. The stretching tube drives the cleaning frame equipped with cleaning rings to continuously scrape back and forth, and the cleaning agent is used to perform deep physical degreasing and cleaning of the surface of the printing plate, ensuring a thorough cleaning effect.

[0013] A further preferred embodiment of the present invention is as follows: a set of recycling plates are inserted on the transmission frame. The recycling plates are open and hollow on the side near the printing plate. A sponge pad is provided inside the recycling plate and the sponge pad rests against both sides of the printing plate. A connection port is provided at the top of the recycling plate for adsorbing the cleaning agent on the surface of the printing plate. Through the hollow recycling plate, the sponge pad and negative pressure adsorption, excess cleaning agent is scraped off while residual moisture is recovered, achieving rapid drying of the surface after cleaning and avoiding residue contamination of subsequent coating processes.

[0014] A further preferred embodiment of the present invention is as follows: a plurality of transmission shafts are rotatably arranged on the unloading rack, a hinge platform is inserted inside the unloading rack, a lifting plate is installed on the top of the hinge platform, a fixing groove is opened on each of the clamping plates, and a plurality of transmission rollers are rotatably arranged inside the fixing grooves, and rubber sleeves are provided on the outside of the transmission rollers. By adjusting the positioning of the straightening rollers and combining the linkage between the lifting plate and the rotating disk, the plate material is stably lifted and accurately flipped 180 degrees, providing automated support for returning to the other side for coating processing. After the plate material is flipped, it is returned to the drying chamber for coating and drying processing on the other side.

[0015] A further preferred embodiment of the present invention is as follows: the visual inspection module is equipped with several cameras to capture the price status of the coating layer during the clamping process, and uses external supplementary lighting to illuminate the surface of the plate. The visual inspection module is used to feed back multi-angle data to the processing center, integrates multi-angle cameras and supplementary lighting system, performs real-time image inspection of the coating layer, can accurately identify defects such as orange peel and wrinkles and screen out defective products, and dynamically adjusts the drying temperature and air volume according to the inspection data to achieve intelligent quality control.

[0016] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention, by setting up a pretreatment mechanism, utilizes a cleaning plate in conjunction with a reciprocating oscillating stretching tube and a cleaning frame to effectively remove surface oil and impurities before the printing plate enters the drying chamber. Furthermore, by combining a recovery plate and a sponge pad, the cleaning agent is recovered under negative pressure, reducing the impact of residue on the subsequent coating quality.

[0017] 2. This invention, by opening a snap-fit ​​groove on the conveyor roller shaft and setting a positioning belt, allows for flexible adjustment of the positioning belt position according to different sizes of printing plates, ensuring that the printing plates remain centered and stable during conveying, reducing offset phenomena, and ensuring that the printing plates are always within the effective drying area of ​​the stepped exhaust vents, thereby improving drying uniformity and efficiency.

[0018] 3. This invention uses a stepped exhaust port and a movable coating mechanism to gradually heat and dry the coating, effectively reducing the skinning phenomenon caused by uneven heating. At the same time, the movable discharge port evenly distributes the material, improving the smoothness and consistency of the coating layer and ensuring the quality of double-sided coating.

[0019] 4. This invention uses a flipping mechanism consisting of a lifting plate, a rotating disk, and a clamping plate on the unloading rack, and combines it with a vision inspection module to perform multi-angle real-time detection of the coating on the plate surface during the flipping process. This enables timely identification of defects such as wrinkles and orange peel, and facilitates dynamic adjustment of drying temperature and airflow, thereby achieving defective product screening and process optimization.

Detailed Implementation

[0023] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes the title of the double-sided coating stepped drying equipment for high-printability, heat-sensitive, double-coated CTP plates. Please refer to [link / reference]. Figures 1-11 Specifically, the equipment for double-sided coating and stepped drying of high-durability heat-sensitive double-coating CTP plates includes a support frame 1 and a drying chamber 11. The drying chamber 11 is equipped with a feeding rack 2 and a unloading rack 4 on the outside. The feeding rack 2 and the unloading rack 4 are installed at both ends of the drying chamber 11. The feeding rack 2 is equipped with a pre-treatment mechanism 3. The pre-treatment mechanism 3 includes a transmission frame 31. A set of cleaning plates 33 is installed inside the transmission frame 31. The cleaning plates 33 are used to adhere to the outside of the plate material for auxiliary cleaning. The unloading rack 4 is equipped with a lifting plate 42. A flipping mechanism for flipping the plate is rotatably mounted on one side of the lifting plate 42. The flipping mechanism includes a rotating disk 43 and a set of clamping plates 44. A vision inspection module 45 is mounted on the outside of the clamping plates 44. The vision inspection module 45 is used to inspect the coating on the surface of the plate. The pretreatment mechanism 3 removes oil and dirt and recovers cleaning agents from the plate, effectively ensuring the surface cleanliness before coating. The positioning belt 16 on the transmission roller 15 prevents the plate from shifting during transport, ensuring that it passes stably through the uniform drying area of ​​the stepped exhaust port 17. The movable discharge port of the coating mechanism 18 achieves uniform material distribution, significantly improving the problems of coating skinning and uneven thickness. The lifting plate 42, rotating disk 43 and clamping plates 44 on the unloading rack 4 enable the plate to flip smoothly, which is convenient for double-sided coating processing. At the same time, the vision inspection module 45 performs multi-angle real-time detection on the coating surface during the flipping process, promptly identifying defects such as wrinkles and orange peel and providing feedback to adjust the drying parameters, effectively improving product yield and process control accuracy.

[0026] like Figure 2 and Figure 4 As shown, a sealing cover plate 12 is installed on the top of the drying chamber 11, and a conveying pipe 13 is installed on the sealing cover plate 12. One end of the conveying pipe 13 is connected to an air inlet device, and a stepped exhaust port 17 is installed at the bottom of the sealing cover plate 12. Several heating wires are installed inside the stepped exhaust port 17. The stepped exhaust port 17 is connected to the conveying pipe 13. The heating wires can heat the airflow, and the coated plate material can be dried step by step according to the stepped exhaust port 17, which can reduce the phenomenon of skin formation caused by uneven heating of the coating during the drying process.

[0027] like Figure 4 As shown, a coating mechanism 18 is installed at the bottom of the sealing cover plate 12. The bottom of the coating mechanism 18 is provided with a movable discharge port for coating the surface of the plate. By using the movable discharge port to press against the top of the plate, the material can be evenly distributed on the surface of the plate, reducing the impact of uneven material distribution on the overall processing quality.

[0028] like Figure 2 and Figure 3 As shown, a set of connecting shafts 14 are installed inside the drying chamber 11. Several transmission rollers 15 are movably arranged between the connecting shafts 14. Several locking ring grooves are opened on the transmission rollers 15, and positioning belts 16 are locked inside the locking ring grooves. The positioning belts 16 are set on the outside of the several transmission rollers 15. The positioning belts 16 are used to abut against both ends of the plate. The position of the positioning belts 16 can be adjusted according to the plate of different sizes, so that the positioning belts 16 can be set on both sides of the plate, reducing the offset of the plate during the conveying process and reducing the position of the plate away from the air outlet, which affects the overall drying efficiency.

[0029] like Figure 5 and Figure 6 As shown, the bottom of the feeding rack 2 is provided with several rotating rollers 25, and the rotating rollers 25 are covered with rubber sleeves. A set of fixed seats 21 is installed inside the feeding rack 2. A transmission plate 22 is movably installed on the top of the fixed seat 21. A reset shaft insert is provided between the transmission plate 22 and the fixed seat 21. An external threaded rod is installed on one side of the fixed seat 21, and the external threaded rod passes through the transmission plate 22. A control turntable 23 is movably installed on the transmission plate 22. The control turntable 23 is threaded onto the external threaded rod. A pressure roller 24 is rotatably arranged between the transmission plates 22. During the operation of the equipment, the rotation of the control turntable 23 can be adjusted to control the height of the pressure roller 24. The height can be adjusted according to the thickness of different plates. As the pressure roller 24 and the rotating rollers 25 rotate, the plate material is fed and moved to the top of the transmission roller shaft 15, so that the plate material is conveyed and dried inside the drying chamber 11.

[0030] like Figure 7 and Figure 9As shown, both ends of the cleaning plate 33 are equipped with extension plates, and the bottom of the extension plates are connected to telescopic end blocks 32. The telescopic end blocks 32 are movably inserted into the transmission frame 31. The transmission frame 31 is equipped with two sets of sliders, and the sliders are installed at one end of the extension plates. The cleaning plate 33 is provided with straight grooves on both sides, and a drive shaft 35 is rotatably installed inside one straight groove. The drive shaft 35 passes through the cleaning plate 33 and is equipped with a connecting rod 351. A set of inclined plates is movably arranged between the connecting rods 351, and a swing shaft 36 is movably hinged inside the inclined plate. A rotating shaft is installed at the top of the swing shaft 36, and a hinge frame 37 is installed on the rotating shaft. A hinge assembly is movably arranged inside the hinge frame 37, and a tension tube 38 is movably clamped at both ends on the other side. The tension tube 38 is connected to the hinge assembly. The tension tube 38 is swung back and forth at both ends of the straight groove by means of the rotation of the drive shaft 35. Several rubber sleeves are externally attached to the drive shaft 35, and the rubber sleeves abut against the surface of the plate. As the plate enters the gap of the cleaning plate 33 and abuts against the rubber sleeves of the drive shaft 35, the drive shaft 35 can be rotated, which can drive the connecting rod 351 to rotate, thereby driving the swing shaft 36 and the top hinge frame 37 to rotate. In conjunction with the movement of the hinge frame 37 and the hinge assembly, the stretching tube 38 can be driven to reciprocate, and in conjunction with the cleaning frame 381, the surface of the plate is cleaned to achieve pretreatment effects such as degreasing and stain removal.

[0031] like Figure 7 and Figure 9 As shown, a telescopic rod is installed inside the stretching tube 38, and a cleaning frame 381 is installed on the stretching tube 38. The cleaning frame 381 consists of several fixed shafts and cleaning rings. The fixed shafts are installed on the outside of the stretching tube 38, and the cleaning rings are evenly distributed on the fixed shafts. The cleaning frame 381 is used to clean the surface of the plate. As the stretching tube 38 reciprocates, the cleaning frame 381 with cleaning rings continuously cleans both sides of the plate, and the surface cleaning agent reduces oil and other residues.

[0032] like Figure 7 and Figure 8 As shown, a set of recycling plates 34 are inserted into the transmission frame 31. The recycling plates 34 are open and hollow on the side near the plate. A sponge pad is installed inside the recycling plate 34 and the sponge pad is against both sides of the plate. A connection port 341 is opened at the top of the recycling plate 34 for absorbing the cleaning agent on the surface of the plate. Combined with the sponge pad against the surface of the plate, the excess cleaning agent is recycled. As the residual water inside the sponge pad can be discharged from the conveying pipe under the action of negative pressure, the surface of the plate can be continuously cleaned and dried, reducing the impact on subsequent coating. The sponge pad can be replaced and maintained regularly.

[0033] like Figure 10 and Figure 11As shown, several transmission shafts 41 are rotatably mounted on the unloading rack 4. A hinge platform 421 is inserted inside the unloading rack 4. A lifting plate 42 is installed on the top of the hinge platform 421. Each clamping plate 44 has a fixing groove, and several transmission rollers are rotatably mounted inside the fixing groove. The transmission rollers are equipped with rubber sleeves. When the plate material is conveyed to the unloading rack 4, the edge of the plate material is between the edge and the clamping plate 44. As the clamping plate 44 moves, it can be corrected in conjunction with the movable rollers and clamped by the clamping plate 44. At this time, the hinge platform 421 at the bottom moves to lift the plate material. As the rotating disk 43 rotates, the plate material can be flipped over. After the plate material is returned, the other side is coated.

[0034] like Figure 10 and Figure 11 As shown, the visual inspection module 45 is equipped with several cameras to capture the coating condition during clamping. External supplementary lighting is used to illuminate the surface of the plate. The visual inspection module 45 is used to feed back multi-angle data to the processing center. The visual inspection module 45 performs real-time detection of the coating on the surface of the plate. During the flipping process, it works with external supplementary lighting to detect whether wrinkles, orange peel, or other defects appear on the surface, thus removing defective products. The internal drying temperature and airflow can be adjusted in real time.

[0035] During use, the printing plate is fed into the pretreatment mechanism 3 via the feeding rack 2. The drive shaft 35 inside the cleaning plate 33 drives the stretching tube 38 to reciprocate, working in conjunction with the cleaning rack 381 to remove oil and dirt. At the same time, the recovery plate 34 uses a sponge pad and negative pressure to remove residual cleaning agent, completing the pretreatment. Then, the printing plate enters the drying chamber 11 and is stably conveyed to the bottom of the coating mechanism 18 via the transfer roller 15 and positioning belt 16. The movable discharge port evenly coats the material. After coating, hot air is delivered through the stepped exhaust port 17 and the conveying pipe 13 to gradually dry the printing plate. To reduce coating skinning, the dried plate is moved to the unloading rack 4, where it is straightened and clamped by the clamping plate 44 and the transmission rollers. It is then lifted by the lifting plate 42 and rotated by the rotating disk 43 to achieve double-sided coating. During the rotation process, the vision inspection module 45 takes pictures from multiple angles and provides feedback on the coating quality. Combined with external supplementary lighting, the data is transmitted to the processing center to adjust the drying parameters in real time. Finally, defective products are screened out. After the inspection is completed, the plate with one side processed can be returned to the drying chamber for processing and inspection of the other side, thus completing the entire double-sided coating and drying process.
