The heating section 13 is configured to generate and deliver hot air, which enters the drying section 12 through the first air duct and the second air duct to dry the fabric inside the drying section 12.

[0035] Specifically, a ventilation plate 121 is provided between the ventilation section 11 and the drying section 12. The ventilation plate 121 has several ventilation holes, and hot air enters the drying section 12 through the ventilation holes on the ventilation plate.

[0050] Specifically, the support assembly includes multiple support rods, with both ends of the support rods connected to the circular mesh 1202 and the rotating shaft.

[0051] The cooperation of the first drive component 1201, the rotary screen 1202, the rotating shaft, and the support component ensures the fabric drying effect while improving the automation level of the drying process and increasing the fabric drying efficiency.

The conveying roller 22 is configured to receive and transport the fabric to cooperate with the circular mesh 1202 to enhance the tension of the fabric.

[0053] Specifically, when the fabric is initially conveyed, it passes the lower end of the conveyor roller 22 and then moves upward to the upper end of the circular mesh 1202, and then downward to the lower end of the circular mesh 1202 of the subsequent adjacent drying mechanism 10; when the fabric leaves the drying oven, the fabric at the upper end of the circular mesh 1202 is conveyed to the lower end of the conveyor roller 22 and then leaves the drying oven.

[0054] Specifically, the base frame 15 is mounted on the base frame 15 of the corresponding drying section 12 by means of bolt assembly.

[0055] Specifically, the conveying assembly 20 is installed at both ends of the oven along the first direction.

[0056] By adding a conveying component 20 to one side of the rotary screen 1202, the conveying roller 22 cooperates with the rotary screen 1202 to enhance the tension of the fabric, prevent the fabric from loosening or wrinkling, ensure the drying effect, and improve the quality of the finished product.
