[0030] See the attached Figures 1-5 As shown, the high-speed continuous drying device for single-layer coated paper in the embodiments of the present utility model includes a housing 1, an anti-warping component 8, and a drying component 2 for drying the single-layer coated paper. One end of the housing 1 is provided with a feed port 5. One end of the feed port 5 is correspondingly provided with a conveyor belt 6. The conveyor belt 6 is located at one end of the anti-warping component 8. The other end of the housing 1 is provided with a discharge port 11. One end of the housing 1 is provided with a motor 7.

[0031] The drying component 2 is located above the conveyor belt 6. One side of the housing 1 is provided with a ventilation port 3. The ventilation port 3 is in communication with the housing 1. A dust-proof net 4 is fixedly installed in the ventilation port 3. The other end of the inner wall of the housing 1 is provided with a transparent observation panel 12.

[0032] The other end of the conveyor belt 6 is provided with a partition 9. There is an empty hole in the middle of the partition 9 which is flush with the conveyor belt 6. One end of the center inside the partition 9 is provided with a first empty groove, and a warm air blower 14 is arranged in the first empty groove.

[0033] One end of the partition 9 is provided with a conveying roller 10. The conveying roller 10 is rotatably installed at one end of the inner wall of the housing 1. One end of the conveying roller 10 is correspondingly provided with a driving roller 13. The other end of the driving roller 13 is connected to the output shaft of the motor 7. There are two groups of conveying rollers 10 which are all driven by the rotation of the driving roller 13.

[0034] The conveyor belt 6 of the above technical solution is arranged at one end of the anti-warping component 8. There is a space between the two groups of conveyor belts 6, which is beneficial to the natural sagging of the single-layer coated paper during transportation, reduces the friction and pulling between the papers, and reduces the possibility of warping and deformation, facilitating the use of the high-speed continuous drying device for single-layer coated paper.

[0035] When the drying component 2 heats and dries the paper transported on the conveyor belt 6, the internal situation can be observed through the transparent observation plate 12 provided at one end of the housing 1, and the distance between the drying component 2 and the paper can be adjusted, which is convenient for drying the paper, thereby improving the overall heat uniformity of the paper. By cooperating with the anti-warping component 8, the problem of warping of the paper during drying can be effectively reduced, ensuring that the paper moves smoothly under the drying component 2. The ventilation opening 3 is provided on one side of the housing 1 to adjust the internal air circulation and ensure the uniformity of the drying effect, avoiding local overheating.

[0036] In order to further improve the drying effect of the paper, in the embodiment of the present utility model, a partition plate 9 is provided at the other end of the conveyor belt 6, and the empty holes provided at one end of the partition plate 9 are flush with the conveyor belt 6, which is convenient for the paper transported on the conveyor belt 6 to move out from the empty holes. During the moving out process, hot air blowers 14 provided at both the upper and lower ends of the inner wall of the partition plate 9 blow air on the paper to supplement heat the paper, blow and heat the areas that are not fully covered, further improving the drying quality, ensuring that the paper receives uniform hot air treatment during transportation. Then, the paper is pulled out from the discharge port 11 by the driving roller 13. As the paper moves, the conveying roller 10 in contact with it rotates, and rotates by relying on the pulling force of the paper and the friction of the roller surface, ensuring that the paper smoothly enters the next process and improving the continuity of the paper during drying.

[0037] See appendix Figure 4 As shown in the figure, the drying component 2 includes a top block 201. The top block 201 is fixedly installed at one end of the upper surface of the housing 1. A second empty slot is provided at the center of the lower surface of the top block 201. An electric push rod 202 is provided in the second empty slot. The piston rod of the electric push rod 202 is connected to an infrared radiation heater 204. The infrared radiation heater 204 is located above the conveyor belt 6. Both ends of the upper surface of the infrared radiation heater 204 are connected to telescopic auxiliary rods 203. The other ends of the telescopic auxiliary rods 203 are provided in the second empty slot opened in the top block 201. The telescopic auxiliary rods 203 expand and contract with the expansion and contraction of the piston rod of the electric push rod 202.

[0038] In order to improve the drying uniformity of the single-layer coated paper, by installing an electric push rod 202 in the second empty slot provided on the lower surface of the top block 201, the piston rod of the electric push rod 202 drives the infrared radiation heater 204 to move up and down, and the height can be adjusted according to the actual heating requirements, optimizing the drying effect and avoiding problems such as uneven drying or overheating caused by improper distance. Driven by the telescopic auxiliary rods 203 provided at both ends of the electric push rod 202 to expand and contract with the electric push rod 202, the stability can be improved during the height adjustment process, improving the practical usability.

[0039] See appendix Figure 5As shown in the figure, the anti-warping assembly 8 includes a double-headed plate 801 and a U-shaped deflector plate 802. There are two sets of double-headed plates 801, which are respectively fixedly installed on both sides of the inner wall of the housing 1. The two sets of double-headed plates 801 are connected by a U-shaped deflector plate 802. An installation hole 803 is provided at one end of each double-headed plate 801. The conveyor belt 6 is located in the installation hole 803. A number of heating holes 804 are formed at one end of the upper surface of the double-headed plate 801, and a heat-receiving hole 805 is provided between each group of heating holes 804. A anti-sinking plate 807 is provided at the upper end of the U-shaped deflector plate 802. Connecting plates 806 are fixedly installed at both ends of the anti-sinking plate 807, and the other ends of the connecting plates 806 are fixedly installed on one side of the double-headed plate 801. The anti-sinking plate 807 is flush with the conveyor belt 6.

[0040] Specifically, the two sets of double-headed plates 801 are connected by a U-shaped deflector plate 802. When the infrared radiation heater 204 heats and dries the paper, it helps to guide the flow of hot air, improve the drying efficiency, enable the paper to be evenly heated, and avoid local overheating or incomplete drying. By providing an anti-sinking plate 807 between the double-headed plates 801 and being flush with the conveyor belt 6, it prevents the paper from sinking and deforming during the drying process. During the drying process of transporting the paper, the paper is placed on the upper surface of the conveyor belt 6. The conveyor belt 6 is arranged in the installation hole 803. There is a space for transporting the paper between the installation hole 803 and the conveyor belt 6, which can restrict the paper and prevent the problem of warping during the drying of the paper, ensuring the drying quality and the smooth transportation of the paper. The heating holes 804 and heat-receiving holes 805 provided on the upper surface of the double-headed plate 801 are conducive to heat transfer and distribution, increasing the heating area of the paper.

[0041] The working principle of the embodiment of the present invention: Place the single-layer coated paper to be dried and processed on the conveyor belt 6, so that the paper enters the housing 1 through the conveyor belt 6. The piston rod of the electric push rod 202 drives the infrared radiation heater 204 to move up and down to heat and dry the paper. The U-shaped deflector plate 802 provided between the double-headed plates 801 helps to guide the flow of hot air at the lower end when the infrared radiation heater 204 heats and dries the paper, enabling the paper to be evenly heated and avoiding local overheating or incomplete drying. By providing an anti-sinking plate 807 between the double-headed plates 801 and being flush with the conveyor belt 6, it prevents the paper from sinking and deforming during the drying process. By arranging the conveyor belt 6 in the installation hole 803, the problem of warping during the drying of the paper is avoided, ensuring the drying quality and the smooth transportation of the paper. The paper is taken out by the driving roller 13 from the empty hole provided at one end of the partition plate 9. During the taking-out process, the warm air blower 14 provided at both the upper and lower ends of the inner wall of the partition plate 9 blows air on the paper to supplement the heating of the paper, blow and heat the area that cannot be completely covered, further improving the drying quality. It is taken out through the discharge port 11 at one end of the driving roller 13 and enters the next processing point to ensure the continuity of the paper during drying.

[0042] The overall structure of the single-layer coated paper high-speed continuous drying device in the embodiment of the utility model is relatively stable during heating, can be adjusted according to the heating requirements, and can effectively solve the uneven heating of the paper, improve the overall uniform heating of the paper, and ensure that the production quality is not affected.

[0043] In the process of drying the paper, the embodiment of the utility model can effectively prevent the problem of warping, ensure the drying quality, continuously dry the paper, and improve the drying efficiency.

[0044] The above shows and describes the basic principle of the invention. The above is only the preferred embodiment of the invention and is not used to limit the invention. The descriptions in the above embodiments and the specification only illustrate the principle of the invention.
