[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. In this solution, the glue application trough is used to store high-strength water-resistant glue, and the glue application roller can limit the double-sided paper, so that the glue in the glue application trough passes through the double-sided paper during the conveying process, so that the glue adheres to the surface of the double-sided paper, thereby realizing the glue application.

[0041] 2. In this scheme, heat exchange coil B is used to transport the hot air discharged from heat exchange coil A. When the hot air passes through heat exchange coil B, it will exchange heat with the water in the preheating box, thereby heating the water and generating steam. Most of the generated steam will remain in the preheating box. When the double-sided coated paper passes through the inside of the preheating box, the moisture in the steam will humidify the double-sided coated paper, thereby increasing the humidity of the double-sided coated paper. At the same time, the high temperature of the steam can heat the double-sided coated paper. Through heating and humidifying the double-sided coated paper, it is more conducive to the application of adhesive to the double-sided coated paper.

[0042] 3. In this solution, the double-sided coated paper can be conveyed by two conveying rollers. At the same time, the two conveying rollers squeeze the double-sided coated paper while conveying it, so that the double-sided coated paper becomes flat. The double-sided coated paper after being heated and humidified can be easily flattened, thus ensuring the uniformity of the glue application when the double-sided coated paper is coated.

[0043] 4. In this solution, the two cleaning rollers can rotate in opposite directions at the same time to clean both sides of the double-sided coated paper, thereby removing the attached impurities. The hot air in the heat exchange coil B can be transported into the two jet pipes through the three-way pipe. The hot air is then sprayed out through the two jet pipes. The sprayed hot air can sweep both sides of the double-sided coated paper and preheat the double-sided coated paper at the same time.

[0044] 5. In this solution, the extension of the electric telescopic rod B can drive the extrusion roller to move, so that the extrusion roller can press down on the double-sided adhesive paper, thereby preventing the double-sided adhesive paper from deviating after glue application. At the same time, it can squeeze the glue application surface of the double-sided adhesive paper to remove air bubbles on the glue application surface and ensure uniform glue application.

[0045] 6. In this solution, the rotating shaft drives the scraper to rotate. The two scrapers can scrape off excess glue from the surface of the double-sided adhesive paper, ensuring uniform glue application. At the same time, the excess glue falls back into the glue application tank under gravity after being scraped off, allowing it to be reused, thereby reducing waste and lowering costs.

[0046] 7. In this solution, two guide rollers are used to transport the double-sided coated paper, allowing it to pass through the drying chamber while remaining taut. A heating fan generates hot air; the working principle and internal structure of the heating fan are common knowledge to those skilled in the art and will not be elaborated here. The hot air is delivered into heat exchange coil A. As the hot air flows within heat exchange coil A, it exchanges heat with the air inside the drying chamber, thereby increasing the temperature inside the drying chamber. This allows the coated double-sided coated paper to dry quickly after entering the drying chamber. The heated air then enters heat exchange coil B through a connecting pipe for secondary heat exchange. Attached Figure Description

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0059] Please see Figures 1-9 The technical solution provided in this embodiment is as follows:

[0060] A sizing apparatus for producing high-strength, water-resistant double-sided offset paper, comprising:

[0061] In a specific embodiment of the present invention, it is composed of a vertical plate 1, a cleaning roller 10, a glue application roller 2, a preheating mechanism, a cleaning mechanism, a pressure roller mechanism, a scraping mechanism, and a drying mechanism. Two vertical plates 1 are symmetrically arranged, and a glue application groove 19 is fixedly connected between the two vertical plates 1. The glue application roller 2 is rotatably mounted on the glue application groove 19.

[0062] In a specific embodiment of the present invention, the glue application groove 19 is used to store high-strength water-resistant adhesive, and the glue application roller 2 is used to limit the movement of the double-sided coated paper, so that the double-sided coated paper passes through the adhesive in the glue application groove 19 during the feeding process, and the adhesive adheres to the surface of the double-sided coated paper, thereby realizing glue application. One-third of the glue application roller 2 is submerged in the adhesive, so that the double-sided coated paper can completely pass through the adhesive.

[0063] Specifically, the preheating components are mounted on two vertical plates 1. The preheating components include a preheating box 20 and a heat exchange coil B33. The preheating box 20 is fixedly connected between the two vertical plates 1. The heat exchange coil B33 is located inside the preheating box 20, and both ends of the heat exchange coil B33 penetrate the preheating box 20 and the two vertical plates 1 and extend to the outside of the two vertical plates 1. The heat exchange coil B33 is located on the lower side of the preheating box 20.

[0064] In a specific embodiment of the present invention, the bottom of the preheating box 20 is used to store water, and the heat exchange coil B33 is set to transport the hot air discharged from the heat exchange coil A31. When the hot air passes through the heat exchange coil B33, it will exchange heat with the water in the preheating box 20, thereby heating the water and generating steam. Most of the generated steam will remain in the preheating box 20. When the double-sided coated paper passes through the inside of the preheating box 20, the moisture in the steam will humidify the double-sided coated paper, thereby increasing the humidity of the double-sided coated paper. At the same time, the high temperature of the steam can heat the double-sided coated paper. By heating and humidifying the double-sided coated paper, it is more conducive to the application of adhesive to the double-sided coated paper.

[0065] Specifically, there are two sets of conveying components, which are symmetrically arranged on two vertical plates 1. Each set of conveying components includes a gear A5 and a conveying roller 6. There are two conveying rollers 6, each of which is rotatably connected between the two vertical plates 1. Both ends of each conveying roller 6 rotatably pass through the two vertical plates 1 and extend to the outside of the two vertical plates 1. There are two gears A5, each of which is fixedly connected to each conveying roller 6. The two conveying rollers 6 mesh with each other.

[0066] The transmission components are located on two sets of conveying components. The transmission components include belts B29 and pulleys B30. There are two belts B29. Each belt B29 is fixedly connected to each conveying roller 6. The belts B29 are driven to the two pulleys B30.

[0067] The driving component is mounted on the vertical plate 1 and is connected to the conveying component. The driving component includes a horizontal plate 27 and a forward and reverse motor 28. The horizontal plate 27 is fixedly connected to the vertical plate 1, and the forward and reverse motor 28 is fixedly connected to the horizontal plate 27. The output end of the forward and reverse motor 28 is fixedly connected to the conveying roller 6.

[0068] In a specific embodiment of the present invention, the double-sided coated paper is conveyed by two conveying rollers 6. At the same time, the two conveying rollers 6 compress the double-sided coated paper while conveying it, thereby making the double-sided coated paper flat. The double-sided coated paper after heating and humidification can be easily flattened, thereby ensuring the uniformity of the double-sided coated paper during glue application. The transmission is carried out by the setting of belt B29 and pulley B30. The conveying rollers 6 are driven to rotate by the output end of the forward and reverse motor 28. Since the two gears A5 mesh with each other, the two conveying rollers 6 rotate in opposite directions at the same time.

[0069] Specifically, there are two side plates 21, and each side plate 21 is fixedly connected to each upright plate 1;

[0070] There are two sets of cleaning components, which are symmetrically arranged on two side plates 21. Each set of cleaning components is connected to each gear A5. Each set of cleaning components includes a pulley A8, a drive belt A9, and a cleaning roller 10. The cleaning roller 10 is rotatably connected between the two side plates 21, and both ends of the cleaning roller 10 rotatably pass through the two side plates 21 and extend to the outside of the two side plates 21. There are two pulleys A8, one of which is fixedly connected to the conveyor roller 6, and the other pulley A8 is fixedly connected to the cleaning roller 10. The drive belt A9 is drivenly connected to the two pulleys A8.

[0071] The purging components are mounted on two vertical plates 1 and connected to the heat exchange coil B33. The purging components include a jet pipe 11 and a three-way pipe 32. There are two jet pipes 11, which are fixedly connected between the two side plates 21 and are symmetrically arranged. One end of the three-way pipe 32 is fixedly connected to the heat exchange coil B33, and the other two ends are fixedly connected to the two jet pipes 11 respectively.

[0072] In a specific embodiment of the present invention, the two side plates 21 are configured to connect the cleaning roller 10 and the air jet pipe 11. The rotation of the conveyor roller 6 drives the pulley A8 to rotate. Since the transmission belt A9 is connected to the two pulleys A8, the two pulleys A8 can rotate simultaneously. The rotation of the conveyor roller 6 drives the cleaning roller 10 to rotate. The two cleaning rollers 10 rotate in opposite directions at the same time, which can clean both sides of the double-sided coated paper at the same time, thereby removing the attached impurities. The hot air in the heat exchange coil B33 can be transported into the two air jet pipes 11 through the three-way pipe 32. The hot air is sprayed out through the two air jet pipes 11. The sprayed hot air can blow on both sides of the double-sided coated paper and preheat the double-sided coated paper at the same time.

[0073] Specifically, the pressure roller mechanism is located on the glue application groove 19. The pressure roller mechanism is used to press the double-sided coated paper, thereby achieving auxiliary glue application and ultimately achieving defoaming of the glued double-sided coated paper. The pressure roller mechanism includes a slide bar 22, an electric telescopic rod B23, a squeeze roller 24, and a U-shaped plate 34. There are two slide bars 22, both of which are movably inserted into one side of the glue application groove 19. Both glue application grooves 19 are movably inserted through the glue application groove 19 and extend to the inner side of the glue application groove 19. The U-shaped plate 34 is fixedly connected to the two slide bars 22 and is located inside the glue application groove 19. The squeeze roller 24 is rotatably connected between the side walls of the U-shaped plate 34 and is aligned with the glue application roller 2. The electric telescopic rod B23 is fixedly connected to the glue application groove 19, and the extended end of the electric telescopic rod B23 movably passes through the glue application groove 19 and is fixedly connected to the U-shaped plate 34.

[0074] In a specific embodiment of the present invention, the extension of the electric telescopic rod B23 can drive the extrusion roller 24 to move, so that the extrusion roller 24 can press down on the double-sided adhesive paper, thereby preventing the double-sided adhesive paper from deviating after glue application. At the same time, it can squeeze the glue application surface of the double-sided adhesive paper to remove air bubbles on the glue application surface and ensure uniform glue application.

[0075] Specifically, the scraping component is mounted on two vertical plates 1. The scraping component includes a gear B17, a rotating shaft 18, and a scraper 35. There are two rotating shafts 18, both of which are rotatably connected between the two vertical plates 1. Both rotating shafts 18 rotatably pass through the two vertical plates 1 and extend to the outer side of the two vertical plates 1. There are two scraper 35, each of which is fixedly connected to each rotating shaft 18. The two scraper 35 are arranged in a figure-eight shape. There are two gears B17, each of which is fixedly connected to each rotating shaft 18. The two rotating shafts 18 mesh with each other.

[0076] In a specific embodiment of the present invention, since the two gears B17 mesh with each other, the two gears B17 can rotate in opposite directions at the same time, so that the included angle generated by the two scrapers 35 can be adjusted. The rotation of the rotating shaft 18 drives the scrapers 35 to rotate, and the two scrapers 35 can scrape off the excess glue on the surface of the double-sided adhesive paper to ensure uniform glue application. At the same time, after the excess glue is scraped off, it falls back into the glue application tank 19 under the action of gravity for reuse, thereby reducing waste and lowering costs.

[0077] Specifically, there are two sets of limiting components, each set of which is located on each vertical plate 1 and connected to the scraping component. The two sets of limiting components are symmetrically arranged. Each set of limiting components includes an electric telescopic rod A3, a through hole 12, a slide rail 13, a T-shaped slider 14, a rack 15, and a spring 16. The slide rail 13 is fixedly connected to the vertical plate 1, the T-shaped slider 14 is slidably connected inside the slide rail 13, the spring 16 is fixedly connected between the T-shaped slider 14 and one inner wall of the slide rail 13, the rack 15 is fixedly connected to the T-shaped slider 14, and the rack 15 meshes with one of the gears B17. The through hole 12 is opened at one end of the slide rail 13, and the electric telescopic rod A3 is fixedly connected to one end of the vertical plate 1.

[0078] In a specific embodiment of the present invention, the slide rail 13 enables the T-shaped slider 14 to slide. The rack 15 meshes with the gear B17, so that the rotation of the gear B17 can drive the rack 15 to move. The movement of the rack 15 can drive the T-shaped slider 14 to move. At the same time, the T-shaped slider 14 compresses the spring 16, and the extension of the electric telescopic rod A3 can push the T-shaped slider 14 to move. The elastic force of the spring 16 can hold the T-shaped slider 14, thereby restricting the movement of the rack 15. This ensures that the scraper 35 is tightly attached to the double-sided adhesive paper. The included angle of the two scrapers 35 can be adjusted according to the thickness of the paper to ensure that it can adapt to double-sided adhesive paper of different thicknesses for adhesive application.

[0079] Specifically, the drying mechanism is located on two vertical plates 1 and is connected to the preheating mechanism. It is used to dry the coated double-sided paper. The drying mechanism includes guide rollers 4, connecting pipes 7, drying chamber 25, heating gas generator 26, and heat exchange coil A31. The connecting pipe 7 is fixedly connected to the heat exchange coil B33. There are two guide rollers 4, both of which are rotatably connected between the two vertical plates 1 and are symmetrically arranged. The drying chamber 25 is fixedly connected between the two vertical plates 1 and is located between the two guide rollers 4. The drying chamber 25 is fixedly connected to the vertical plate 1. The heat exchange coil A31 is located inside the vertical plate 1, and both ends of the heat exchange coil A31 pass through the drying chamber 25 and the two vertical plates 1. One end of the heat exchange coil A31 is fixedly connected to the drying chamber 25, and the other end of the heat exchange coil A31 is fixedly connected to the connecting pipe 7.

[0080] In a specific embodiment of the present invention, two guide rollers 4 are used to transport the double-sided coated paper, allowing it to pass through the drying chamber 25 while remaining taut as it enters the chamber. A heating fan 26 generates hot air. The working principle and internal structure of the heating fan 26 are common knowledge to those skilled in the art and will not be described in detail here. The heating fan 26 delivers the generated hot air into the heat exchange coil A31. As the hot air flows within the heat exchange coil A31, it exchanges heat with the air inside the drying chamber 25, thereby increasing the temperature inside the drying chamber 25. This allows the coated double-sided coated paper to dry quickly after entering the drying chamber 25. The heat exchanged hot air then enters the heat exchange coil B33 through the connecting pipe 7 for secondary heat exchange.

[0081] The working principle of the sizing device for producing high-strength water-resistant double-sided coated paper provided by the present invention is as follows: the output end of the forward and reverse motor 28 rotates to drive the conveyor roller 6 to rotate, the conveyor roller 6 rotates to drive the gear A5 to rotate, and since the two gears A5 mesh with each other, the two conveyor rollers 6 rotate in opposite directions at the same time. The rotation of the conveyor roller 6 drives the pulley B30 to rotate, the pulley B30 rotates to drive the belt B29 to rotate, and the belt B29 rotates to drive the two pulleys B30 to rotate at the same time.

[0082] The rotation of conveyor roller 6 drives pulley A8 to rotate, pulley A8 drives drive belt A9 to rotate, drive belt A9 drives both pulleys A8 to rotate simultaneously, and pulley A8 drives cleaning roller 10 to rotate.

[0083] The setting of the glue roller 2 can press the double-sided adhesive paper into the glue trough 19. The electric telescopic rod B23 extends and drives the U-shaped plate 34 to move. The movement of the U-shaped plate 34 drives the slide rod 22 to move on the glue trough 19. The movement of the U-shaped plate 34 drives the extrusion roller 24 to move. The movement of the extrusion roller 24 cooperates with the glue roller 2 to press the double-sided adhesive paper.

[0084] The electric telescopic rod A3 extends and pushes the T-shaped slider 14 to slide within the slide rail 13. After the T-shaped slider 14 moves, it compresses the spring 16. The guide roller 4 moves and drives the rack 15 to move. The rack 15 moves and drives the gear B17 to rotate. The rotation of the gear B17 drives the rotating shaft 18 to rotate. Since the two gears B17 mesh with each other, the two gears B17 rotate in opposite directions at the same time. The rotation of the rotating shaft 18 drives the scraper 35 to rotate, thereby adjusting the included angle of the two scrapers 35.

[0085] Two guide rollers 4 are used to transport the double-sided coated paper, allowing it to pass through the drying chamber 25. The hot air generated by the heating gas generator 26 enters the heat exchange coil A31, where it exchanges heat with the gas inside the drying chamber 25, thus raising the temperature. The coated paper can then be dried inside the drying chamber 25. The hot air after heat exchange in the heat exchange coil A31 enters the heat exchange coil B33 through the connecting pipe 7. As the hot air flows through the heat exchange coil B33, it heats the water inside the preheating chamber 20, generating steam. The hot air inside the heat exchange coil B33 then enters the two jet pipes 11 through the three-way pipe 32, and is then sprayed out through the two jet pipes 11 to purge the coated paper and preheat it simultaneously.
