[0030] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0031] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] See also Figure 1-Figure 3 A paper drying device includes a box body 1, a bottom frame 2, a fixing frame 3, a magnet 4 and a motor 14. Specifically, the interior of the box body 1 is a rectangular space structure, and an air inlet 6 is respectively arranged at the bottom of both sides of the box body 1, and an air outlet 7 is arranged at the top of the box body 1.

[0035] The two ends of the bottom frame 2 are rotatably connected to the inner wall of the box body 1 through a rotating shaft 5, and a fixing frame 3 is covered on the bottom frame 2. The bottom frame 2 and the fixing frame 3 are both rectangular frame structures with the same size. A magnet 4 is respectively provided on the fixing frame 3 and the bottom frame 2. The two magnets 4 correspond to each other, and when the fixing frame 3 covers the bottom frame 2, the two opposite magnetic poles of the two magnets 4 are attracted.

[0036] The motor 14 is disposed in the housing 1 , and the output shaft of the motor 14 is rotatably connected to a rotating shaft 5 at one end of the bottom frame 2 , and driven by the motor 14 , the bottom frame 2 can rotate 90°.

[0037] The working principle of this embodiment is to first set an air inlet 6 at the bottom of both sides of the box body 1, and set an air outlet 7 at the top of the box body 1, and introduce warm air into the box body 1 through the two air inlets 6 and output it from the air outlet 7.

[0038] When the entire device is not working, the bottom frame 2 is in a horizontal position to facilitate laying of paper. After the paper is laid, the paper is pressed onto the bottom frame 2 by the fixing frame 3, and then the fixing frame 3 and the bottom frame 2 are connected by the magnet 4. Finally, the motor 14 drives the bottom frame 2 to rotate 90° and starts the drying work.

[0039] When the warm air is in the box 1, it contacts the paper on the bottom frame 2, thereby taking away the moisture on the paper and exhausting it from the box 1 through the air outlet 7. In the process of drying the paper, the paper is in a vertical state, so that both surfaces of the paper are evenly contacted with the warm air, and at the same time, water droplets can be prevented from falling back onto the paper.

[0040] In one specific embodiment:

[0041] Three groups of bottom frames 2 and fixing frames 3 are arranged in the box body 1 . The rotating shafts 5 of the three bottom frames 2 are distributed on the three vertices of an equilateral triangle, and the spacing between the rotating shafts 5 on the three bottom frames 2 is greater than the width of one bottom frame 2 .

[0042] The rotating shafts 5 of the three bottom frames 2 are all dynamically connected to the output shaft of the motor 14, so that the motor 14 can directly drive the three bottom frames 2 to rotate 90 degrees at the same time.

[0043] In this embodiment, the working efficiency of the drying device is increased by increasing the number of bottom frames 2 and fixing frames 3.

[0044] In another specific embodiment:

[0045] Two magnets 4 are respectively disposed at both ends of the bottom frame 2 and the fixing frame 3 , so that a total of four pairs of magnets 4 are disposed on the bottom frame 2 and the fixing frame 3 , thereby enhancing the connection strength between the bottom frame 2 and the fixing frame 3 .

[0046] In another specific embodiment:

[0047] The drying device further comprises a connecting rod 8, a driving rod 9, a rotating disk 10, a worm wheel 11 and a worm 12. Specifically, a connecting rod 8 is provided on the rotating shaft 5 at one end of each bottom frame 2, one end of the connecting rod 8 is fixedly provided on the rotating shaft 5, and the length direction of the connecting rod 8 is perpendicular to the axis of the rotating shaft 5. A strip groove 13 is provided on one end of the connecting rod 8 away from the rotating shaft 5.

[0048] One end of the driving rod 9 is slidably disposed in the strip groove 13, and the other end is fixedly disposed on the turntable 10, and the turntable 10 is rotatably disposed on the box body 1, and the axis of the turntable 10 is parallel to the axis of the rotating shaft 5, and the turntable 10 is located at the center of the equilateral triangle where the three rotating shafts 5 are located at the same end of the three bottom frames 2. The length direction of the driving rod 9 is perpendicular to the axis of the rotating shaft 5.

[0049] Three driving rods 9 are evenly distributed around the rotating disk 10 , and the three driving rods 9 are respectively connected to the strip grooves 13 on the three connecting rods 8 .

[0050] A worm wheel 11 is coaxially arranged on the turntable 10 , and a worm 12 is matched with the worm wheel 11 . One end of the worm 12 is coaxially connected to the output shaft of the motor 14 .

[0051] In this embodiment, the worm 12 is driven to rotate by the motor 14, so that the engagement of the worm 12 with the worm wheel 11 is realized to drive the turntable 10 and the driving rod 9 to rotate, and the sliding fit between the end of the driving rod 9 and the strip groove 13 is realized to drive the connecting rod 8 to rotate by the driving rod 9, thereby rotating the rotating shaft 5 and the bottom frame 2 by 90°.

[0052] In another specific embodiment:

[0053] The teeth on the worm wheel 11 are distributed in a sector-shaped area to form sector-shaped teeth, and the center angle corresponding to the sector-shaped area is between 90° and 110°. When the bottom frame 2 is in a vertical state, one end of the sector-shaped teeth meshes with the worm 12, and when the bottom frame 2 is in a horizontal state, the other end of the sector-shaped teeth meshes with the worm 12.

[0054] By limiting the existing area of ​​the teeth on the worm wheel 11, the maximum angle of each rotation of the worm wheel 11 is limited, thereby limiting the angle of each rotation of the driving rod 9 and the connecting rod 8 to drive the rotating shaft 5 and the bottom frame 2.

[0055] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
