[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-7 This utility model provides a technical solution for a textile drying device.

[0038] A textile drying apparatus, comprising:

[0039] The drying chamber 1 has a drying cavity 2 inside. The drying cavity 2 has a drying inlet 3 and a drying outlet 4 at both ends. The upper side wall of the drying cavity 2 has an air inlet 5. A heating tube 6 is fixed on the air inlet 5. A heating element is installed inside the heating tube 6.

[0040] Air intake fan 7, the air outlet of air intake fan 7 is connected to heating pipe 6;

[0041] The exhaust fan 8 has an air inlet that is connected to the drying chamber 2.

[0042] The first rotating roller 9 is rotatably connected inside the drying chamber 2. The first rotating roller 9 is provided with a first heat exchange chamber 10. The first heat exchange chamber 10 is provided with a first heat exchange inlet 11 and a first heat exchange outlet 12 at both ends.

[0043] The second rotating roller 13 is rotatably connected inside the drying chamber 2. The second rotating roller 13 is provided with a second heat exchange chamber 14. The two ends of the second heat exchange chamber 14 are provided with a second heat exchange inlet 15 and a second heat exchange outlet 16. The first heat exchange inlet 11 and the second heat exchange inlet 15 are connected to the air outlet of the air blower 8.

[0044] During the drying process, the textile 17 (fabric) passes sequentially through the drying inlet 3, between the first rotating roller 9 and the second rotating roller 13, and the drying outlet 4. Air enters the drying chamber 2 through the air outlet of the air inlet fan 7 and the heating pipe 6. The hot air, heated by the heating element, heats and dries the textile 17. The air outlet fan 8 extracts the air from the drying chamber 2, thereby removing the internal water vapor. The extracted air enters the first heat exchange chamber 10 and the second heat exchange chamber 14, thereby heating the first rotating roller 9 and the second rotating roller 13. Then, it is discharged from the first heat exchange outlet 12 and the second heat exchange outlet 16, respectively. The first rotating roller 9 and the second rotating roller 13 can preheat and dry the textile 17, and can utilize the heat of the discharged air, making it more energy-efficient.

[0045] The first rotating roller 9 includes a first roller body 18, a first heat exchange inlet pipe 19 and a first heat exchange outlet pipe 20 fixed at both ends of the first roller body 18, and a first through hole 21 provided on two opposite side walls of the drying chamber 2. The first heat exchange inlet pipe 19 and the first heat exchange outlet pipe 20 are respectively inserted into the two first through holes 21, thereby enabling the first roller body 18 to rotate relative to the first through holes 21.

[0046] The second rotating roller 13 includes a second roller body 22, a second heat exchange inlet pipe 23 and a second heat exchange outlet pipe 24 fixed at both ends of the second roller body 22, and a second lifting groove 25 provided on two opposite side walls of the drying chamber 2.

[0047] After the textile 17 passes between the first roller 18 and the second roller 22, the second roller 22 presses the textile 17 onto the first roller 18, thereby enabling closer contact between the textile 17 and the roller and increasing the drying effect.

[0048] The textile drying device 17 also includes two second lifting components, which correspond one-to-one with the second heat exchange inlet pipe 23 and the second heat exchange outlet pipe 24, such as... Figure 5 As shown, the second lifting assembly includes:

The second heat exchange inlet pipe 23 and the second heat exchange outlet pipe 24 are connected to the lifting holes 29 of the two lifting sliders 28 respectively.

[0051] The lifting slider 28 can block the second lifting groove 25, and the second heat exchange inlet pipe 23 and the second heat exchange outlet pipe 24 can rotate relative to the lifting hole 29.

[0052] like Figure 5 As shown, a second rotating ring groove 30 is provided on the outer wall of the second heat exchange inlet pipe 23. A second rotating ring 31 is installed in the second rotating ring groove 30. A connecting pipe 32 is fixed on the second rotating ring 31. The connecting pipe 32 includes a connecting horizontal pipe 33 and a connecting vertical pipe 34. An air outlet pipe 35 is connected to the air outlet of the air outlet fan 8. The air outlet pipe 35 is fixedly connected to the outer wall of the drying chamber 1. A lower insertion pipe 36 is provided on the air outlet pipe 35. The lower insertion pipe 36 is inserted into the connecting vertical pipe 34.

[0053] With the above configuration, when the second roller 22 rotates, the second heat exchange inlet pipe 23 can rotate relative to the rotating ring, thus not affecting the normal rotation of the second roller 22. When adjusting the height of the second roller 22, the connecting vertical pipe 34 moves up and down relative to the lower insertion pipe 36, thus not affecting the height adjustment of the second roller 22.

[0054] like Figure 5As shown, the second lifting assembly also includes a fixing block 37, a fixing shaft 38, and a pressure spring 39. The fixing block 37 is fixed to the outer wall of the drying chamber 1, and a fixing hole 40 is provided on the fixing block 37. The fixing shaft 38 is fixed to the upper side of the lifting slider 28, and the upper end of the fixing shaft 38 is inserted into the fixing hole 40. The pressure spring 39 is sleeved on the fixing shaft 38 and is located between the fixing block 37 and the lifting slider 28. The pressure spring 39 can apply downward pressure to the lifting slider 28, thereby enabling the second roller 22 to be better pressed onto the textile 17.

[0055] The first heat exchange chamber 10 is provided with a first spiral protrusion 41, which can increase the contact area with the drawn-in air and improve the heat exchange effect. Similarly, the second heat exchange chamber 14 is provided with a second spiral protrusion 53.

The heating rod 46 is fixed to the inner wall of the heating tube 6, the heating column 47 is fixed to the heating rod 46, and the heating wire 48 is spirally fixed to the heating column 47. The heating wire 48 is spirally arranged. The textile drying device also includes a heating cover 49, which is fixed to the upper inner wall of the drying chamber 2 via an upper tube 50. The heating cover 49 has a cover cavity 51 inside, and the lower side wall of the cover cavity 51 has several cover perforations 52. The cover cavity 51 communicates with the heating tube 6.

[0058] Heating wire 48 heats the air drawn in by air intake fan 7, which then enters the cover cavity 51 and is blown onto textile 17 through cover perforation 52 for drying.
