[0053] The hot air guiding mechanism 5 can guide the hot air to flow in an S shape from the outlet end of the drying chamber main body 1 to the inlet end of the drying chamber main body 1 .

[0054] Moreover, a conventional drying heating pipe can also be installed in the drying chamber body 1.

[0055] In this embodiment, when the painted metal leisure chair frame is dried, the frame moves along the conveying track 2 to the drying chamber main body 1, and hot air is generated in the hot air unit 4 and conveyed to the hot air guide mechanism 5. Under the action of the hot air guide mechanism 5, the hot air flows in an S shape from the outlet end of the drying chamber main body 1 to the inlet end of the drying chamber main body 1. The temperature of the hot air gradually decreases during the flow, so that the temperature inside the drying chamber main body 1 gradually increases from the inlet end to the outlet end. After the frame enters the drying chamber main body 1, the temperature also gradually rises, thereby preventing defects in the paint surface due to sudden changes in temperature, and improving the drying effect of the skeleton paint surface.

[0056] Example 2:

[0057] This embodiment provides a coating drying device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the hot air guide mechanism 5 further includes: an initial air outlet 50, which is arranged on the inner wall of the drying chamber body 1 and located at the outlet end of the drying chamber body 1; a final return air outlet 51, which is arranged on the inner wall of the drying chamber body 1 and located at the inlet end of the drying chamber body 1; a plurality of intermediate air outlets, which are arranged on the inner walls of both sides of the drying chamber body 1, and the plurality of intermediate air outlets include a plurality of intermediate air outlets 52 and a plurality of intermediate return air outlets 53;

The initial air outlet 50 corresponds to an intermediate return air outlet 53 on the inner wall of the drying chamber main body 1 on the opposite side, and the final return air outlet 51 corresponds to an intermediate air outlet 52 on the inner wall of the drying chamber main body 1 on the opposite side, and the intermediate return air outlets 53 and the intermediate air outlets 52 are connected in pairs.

[0060] In this embodiment, after the hot air unit 4 generates hot air, the hot air first moves to the initial air outlet 50 and is discharged into the drying chamber main body 1 from the initial air outlet 50, and then the hot air enters the intermediate return air outlet 53 corresponding to the initial air outlet 50 on the side wall of the other side of the drying chamber main body 1, and moves from the intermediate return air outlet 53 to the adjacent intermediate air outlet 52, and then is discharged into the drying chamber main body 1 from the intermediate air outlet 52, and then enters the intermediate return air outlet 53 corresponding to the side wall of the other side of the drying chamber main body 1 again, forming an S-shaped flow path in this way, and finally is received by the final return air outlet 51 and returns to the hot air unit 4, so that the temperature inside the drying chamber main body 1 gradually increases from the inlet end to the outlet end.

[0064] The dehumidification unit further includes: a fixed orifice plate 6, which is disposed in the dehumidification box 43; a movable orifice plate 7, which is movably disposed in the dehumidification box 43; a moisture-absorbing cotton 8, which is disposed between the fixed orifice plate 6 and the movable orifice plate 7; and a drain port 9, which is disposed at the bottom of the dehumidification box 43 and below the moisture-absorbing cotton 8.

[0065] The drain port 9 can discharge the moisture squeezed out of the moisture-absorbing cotton 8 out of the dehumidification box 43 .

[0066] Moreover, the heating part 42 is a conventional heating device, and the movable orifice plate 7 is installed in the dehumidification box 43 by a conventional movable connection method. For example, a guide groove is opened on the side wall of the dehumidification box 43, and guide blocks cooperating with the guide groove are installed on both sides of the movable orifice plate 7.

After the hot air returns to the air inlet box 44, it is moved to the dehumidification box 43 by the air inlet box 44. When the hot air passes through the hygroscopic cotton 8, the moisture carried in the hot air is absorbed by the hygroscopic cotton 8, thereby improving the dryness of the hot air. After the hygroscopic cotton 8 absorbs a large amount of moisture, the movable orifice plate 7 is moved close to the fixed orifice plate 6 to squeeze the hygroscopic cotton 8 and squeeze out the moisture absorbed by the hygroscopic cotton 8. The squeezed out moisture can be discharged from the dehumidification box 43 through the drain port 9. Compared with the prior art, the utility model can effectively improve the dryness of the hot air, thereby improving the drying effect of the hot air, and at the same time can automatically maintain the hygroscopic cotton 8, thereby improving the stability of the dehumidification box 43.
