After pressing and dewatering, the sheet is dried into paper. During the use of paper, drying is usually required.
[0003] The existing Chinese patent with publication number CN220789244U discloses a paper dryer. The existing technical solution has the following defects: Although the above technical solution uses a conveyor belt with drying holes, uses heating tubes to generate heat, and uses a fan to enhance airflow to exhaust the steam generated during paper drying, the drying is more uniform, the steam affects the drying effect, and the drying efficiency is improved. However, in the above technical solution, the paper may wrinkle due to loss of moisture during drying. The above technology lacks a leveling mechanism to level the wrinkles on the paper, which can easily affect the subsequent processing of the paper and reduce its practicality. Utility Model Content

[0024] Please refer to Figure 1-4A hot air rapid drying device for paper includes a housing 1. A through-hole 2 is provided at the middle of both sides of the housing 1, and a conveying roller 3 passes through the through-hole 2. A fixing block 4 is provided between the conveying roller 3 and the housing 1. A connecting frame 6 is provided on the lower top surface and the upper bottom surface of the housing 1, and an air outlet 11 passes through the connecting frame 6. An electric heating wire 10 is installed inside the connecting frame 6. A bushing is provided on the top surface and the bottom surface of the housing 1, and a rotating rod 9 passes through the bushing. One end of the rotating rod 9... Inside the connecting frame 6, there is a fan blade 8. A dual-axis motor 23 is mounted on the rear surface of the housing 1. The output end of the dual-axis motor 23 and one end of the rotating rod 9 are provided with a synchronous pulley 24. A synchronous belt 25 is provided between the synchronous pulleys 24. Through slots 7 are provided on both sides of the top surface of the housing 1. A lower pressure roller 13 is provided on one side of the upper surface of the bottom end of the housing 1. A rack 19 is provided on one side of the top surface of the housing 1. One end of the rack 19 is located inside the housing 1 and is provided with an upper pressure roller 12. One side of the rack 19 is located on the surface of the top end of the housing 1. A connecting block 20 is provided, and one end of the connecting block 20 extends into the interior of the connecting groove 21 opened on one side of the inner wall of the box 1. A second motor 18 is installed on one side of the top surface of the box 1, and a gear 17 is fixedly connected to the output end of the second motor 18. The gear 17 meshes with the rack 19. Paper is placed on the conveying roller 3, and the paper is conveyed into the box 1 by the use of the conveying roller 3. The dual-axis motor 23 on the rear surface of the box 1 is turned on. The dual-axis motor 23 drives the synchronous wheel 24 to rotate. Then, the synchronous belt 25 drives the rotating rod 9 to rotate, so that the fan blade 8 at one end of the rotating rod 9 rotates. Then, the heating wire 10 in the connecting frame 6 is used to dry the paper in the box 1 with hot air, so that the moisture on the surface of the paper can evaporate quickly. The use of two connecting frames 6, fan blade 8, and heating wire 10 can dry the top and bottom surfaces of the paper at the same time, which can improve the drying speed of the paper and thus improve its working efficiency.
[0025] In one embodiment, a mounting frame 16 is provided on one side surface of the housing 1 below the opening 2, and a first motor 14 is mounted on the front end surface of the mounting frame 16. The output end of the first motor 14 is fixedly connected to a take-up roller 15. After the paper is leveled, the first motor 14 on the front end surface of the mounting frame 16 is turned on, and the first motor 14 drives the take-up roller 15 to rotate, so as to take up the dried and leveled paper, thereby facilitating the subsequent processing of the dried and leveled paper and improving its practicality.
[0026] In one embodiment, the upper pressure roller 12 is movably connected to the housing 1, and the lower pressure roller 13 is fixedly connected to the housing 1. The upper pressure roller 12 and the lower pressure roller 13 correspond to each other. By opening the second motor 18 on one side of the top surface of the housing 1, the second motor 18 drives the gear 17 to rotate. While the gear 17 is rotating, it drives the rack 19 to move. While the rack 19 is moving, it drives the upper pressure roller 12 to move. When the upper pressure roller 12 and the lower pressure roller 13 come into contact, the surface of the paper can be flattened by the cooperation of the upper pressure roller 12 and the lower pressure roller 13, reducing wrinkles on the paper.
[0027] In one embodiment, the front surface of the housing 1 is provided with an observation window 22, and a sealing strip is provided between the observation window 22 and the housing 1. The working condition inside the housing 1 can be observed by using the observation window 22, and the sealing strip can improve the sealing between the observation window 22 and the housing 1.
[0028] In one embodiment, the bottom surface of the box 1 is provided with support legs 5 on both sides. There are multiple support legs 5, and the multiple support legs 5 are evenly distributed in pairs on both sides of the bottom surface of the box 1. The support legs 5 support the box 1, which helps to improve the stability of the box 1.

By using the two connecting frames 6, fan blades 8, and heating wires 10, the top and bottom surfaces of the paper can be dried simultaneously, which can improve the drying speed of the paper and thus improve its working efficiency.
[0030] In one embodiment, the connecting block 20 and the connecting groove 21 are rectangular structures, and the connecting block 20 and the connecting groove 21 are slidably connected. The use of the connecting block 20 and the connecting groove 21 can limit the rack 19, thereby facilitating the maintenance of the stability of the rack 19 during movement.
[0031] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.
[0032] Working principle:
[0033] In use, paper is placed on the conveyor roller 3, which transports the paper into the housing 1. The dual-axis motor 23 on the rear surface of the housing 1 is then activated. The motor 23 drives the synchronous pulley 24 to rotate, which in turn drives the rotating rod 9 via the synchronous belt 25. This causes the fan blade 8 at one end of the rotating rod 9 to rotate, and the heating wire 10 in the connecting frame 6 provides hot air drying for the paper in the housing 1, allowing the moisture on the paper surface to evaporate quickly. The use of the two connecting frames 6, fan blade 8, and heating wire 10 allows for simultaneous drying of both the top and bottom surfaces of the paper, improving the drying speed and thus increasing work efficiency. By opening the second motor 18 on one side of the top surface of the housing 1, the second motor 18 drives the gear 17 to rotate. While the gear 17 is rotating, it drives the rack 19 to move. While the rack 19 is moving, it drives the upper pressure roller 12 to move. When the upper pressure roller 12 and the lower pressure roller 13 come into contact, the surface of the paper can be flattened by the cooperation of the upper pressure roller 12 and the lower pressure roller 13, reducing wrinkles on the paper. After the paper is flattened, the first motor 14 on the front surface of the mounting frame 16 is opened. The first motor 14 drives the winding roller 15 to rotate, which can wind up the dried and flattened paper, thus facilitating subsequent processing of the dried and flattened paper and improving its practicality.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
