Sliding holes for sliding of the two connecting sliders are opened on the side wall of the coating box. The two connecting sliders are respectively connected to the two racks. The first electric push rod is mounted on the coating box and its output shaft is connected to the upper scraper.

[0015] Preferably, the second power mechanism includes a first servo motor, a threaded rod, and two sets of telescopic components. The two sets of telescopic components are respectively located at both ends of the inner side of the coating box. Each telescopic component includes a sleeve and a sliding rod.

[0023] Example 1

[0024] like Figures 1-3 As shown in the figure, the high-efficiency coating device for producing coated paper proposed in this embodiment includes a coating box 1, a second power mechanism, a clamping mechanism, two nozzles 2, two scrapers 3, and two heating nozzles 4.

[0025] The coating box 1 has openings at both ends; two nozzles 2 are installed inside the coating box 1 and are arranged symmetrically up and down; a feeding device is connected to each of the two nozzles 2; a recycling box 23 is provided inside the coating box 1, which is used to recycle excess material dripping from the paper.

[0026] Both scrapers 3 are slidably mounted inside the coating box 1. The coating box 1 is equipped with a first power mechanism for driving the two scrapers 3 to move closer or further apart. The first power mechanism includes a first electric push rod 11 and a transmission assembly. The transmission assembly includes a gear 16 and two racks 17. A gear mounting bracket 19 is connected to the outer wall of the coating box 1. The gear 16 is rotatably mounted on the gear mounting bracket 19. Both racks 17 are slidably mounted on the outer wall of the coating box 1 and are meshed with the gear 16. Both scrapers 3 are connected to connecting sliders 7. The side wall of the coating box 1 has sliding holes for the two connecting sliders 7 to slide. The two connecting sliders 7 are respectively connected to the two racks 17. The first electric push rod 11 is mounted on the coating box 1 and its output shaft is connected to the upper scraper 3.

[0027] Two heating nozzles 4 are symmetrically arranged inside the coating box 1, and the two heating nozzles 4 are fixedly connected to the two scrapers 3 respectively; a heating device is connected to each of the two heating nozzles 4.

[0028] The clamping mechanism includes a base plate 12, a clamping plate 13 disposed above the base plate 12, and a second electric push rod 21 mounted on the base plate 12 for driving the clamping plate 13 to rise and fall. A mounting bracket 22 is fixed on the base plate 12, and the second electric push rod 21 is mounted on the mounting bracket 22 and its output shaft is connected to the clamping plate 13.

[0029] The second power mechanism is installed on the coating box 1 to drive the base plate 12 to move. The second power mechanism includes a first servo motor 10, a threaded rod 24 and two sets of telescopic components. The two sets of telescopic components are respectively located at both ends of the inner side of the coating box 1. The telescopic components include a sleeve 8 and a slide rod 9. The sleeve 8 is connected to the inner wall of the coating box 1. The end of the slide rod 9 is slidably installed on the inner side of the sleeve 8. The outer ends of the two slide rods 9 are connected to the connecting frame 20. The two ends of the base plate 12 are respectively connected to the connecting frames 20 on both sides. The threaded rod 24 is rotatably installed in the sleeve 8 on one side. A threaded groove adapted to the threaded rod 24 is opened on the corresponding slide rod 9. The first servo motor 10 is installed on the coating box 1 and its output shaft is connected to the threaded rod 24.

[0030] The lower roller 51 is rotatably installed inside the coating box 1, and the upper pressure roller 52 is set above the lower roller 51. Sliding seats 6 are slidably installed on both sides of the inner wall of the coating box 1. The upper pressure roller 52 is rotatably installed between the two sliding seats 6. The paper is passed between the lower roller 51 and the upper pressure roller 52. The upper pressure roller 52 applies a certain pressure to the paper, thereby limiting the paper and flattening the paper.

[0031] Furthermore, this technical solution also includes a PLC controller, which plays a role in controlling and processing data.

[0032] In this embodiment, the paper is pulled out from the unwinding roller, so that the outer end of the paper passes through the space between the lower roller 51 and the upper pressure roller 52 and between the two nozzles 2. In the initial state, the two scrapers 3 are far apart, and the base plate 12 is located between the two scrapers 3. The end of the paper is placed between the base plate 12 and the clamping plate 13. Then, the clamping plate 13 is driven to move downward by the second electric push rod 21 to clamp the paper.

[0033] The raw material for spraying is supplied to the two nozzles 2 by a feeding device. It should be noted that the feeding device includes a material tank and a pump. The material tank is used to store liquid raw material, and the pump is used to pump the raw material to the nozzles 2 through the pipeline. The raw material is sprayed onto the surface of the paper through the two nozzles 2. In addition, the feeding device can also choose another feeding method, that is, the material tank is placed above the coating box 1, and the material tank is supported by a bracket. Pipes are connected between the material tank and the two nozzles 2, and valves are installed on the pipes. After the valves are opened, the material inside the material tank flows to the nozzles 2 through the pipes under the action of gravity.

[0034] The second power mechanism drives the base plate 12 to move outward, thereby moving the paper outward. When the base plate 12 moves past the position of the heating nozzle 4, the first power mechanism immediately drives the two scrapers 3 to move closer together, thereby moving the two heating nozzles 4 closer together. The two heating nozzles 4 can scrape off excess material on the paper and can smooth the material on the paper.

[0035] Hot air is supplied to the two heating nozzles 4 by a heating device. It should be added that the output end of the hot air blower 18 is connected to a three-way pipe, and the two output ends of the three-way pipe are respectively connected to two high-temperature resistant hoses. The other ends of the two high-temperature resistant hoses are respectively connected to the two heating nozzles 4. The hot air generated by the hot air blower 18 is delivered to the two heating nozzles 4 and sprayed onto the two sides of the paper, thereby accelerating the drying speed of the raw materials on the paper surface.

[0036] When the base plate 12 moves outward to the specified position, the equipment stops working briefly, the paper is released from clamping, the end of the paper is fixed on the take-up roller, and the paper is pulled by the rotation of the take-up roller itself, thereby realizing the continuous and uninterrupted coating operation of the paper.

Through the above structure, the flow range of the hot air blown out by the heating nozzle 4 on the paper surface can be increased, thereby improving the hot air utilization efficiency and improving the drying effect on the raw materials.
