At the same time, the circulating fan starts working, sending the hot air generated by the burner into the air supply box through the gas duct. Part of the hot air enters the shrinking air duct through the air supply box, and then passes through the wave air duct to form a certain wind pressure and wind speed, so that the textiles are completely driven by the air flow without the need for traction belts, and the textiles are evenly dried; Part of the hot air enters the upper air duct 1 and upper air duct 2 through the air supply box, and the hot air is blown to the conveyor belt through the upper air duct blowing port, so that the violently shaking textiles can fall steadily on the conveyor belt, further accelerating the drying process; (3) After a sufficient drying time, the textiles will be transported to the output port of the drying oven by the conveyor belt. At the output port, the cloth traction roller starts to work and outputs the dried textiles at a uniform speed.

[0015] The technical problem to be solved by the present invention can also be further achieved through the following technical solutions. For the above-mentioned high-efficiency and energy-saving fluffy drying method, during the drying process, the mesh belt body is adjusted by the mesh belt traction roller, the mesh belt correction roller, and the mesh belt tensioning roller, so that the textiles are output to the outside of the oven without tension.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The main frame of the oven of the present invention is welded with 10# channel steel. The burner is fixed near the circulating fan, which greatly shortens the travel of the heating zone. The upper and lower bottom frames of the oven are filled with rock wool, and the surroundings are sealed with insulation boards filled with rock wool. The closed structure greatly reduces the heat radiation loss, saves energy and improves the production environment. 2. Excess hot air will be blown out at the inlet of the air supply box of the present invention. The air supply box and the circulating fan are designed to be at a distance from the inlet of the oven so that there is enough space for the air to be recycled in the oven, thus saving energy and improving the production environment. 3. The air supply box of the present invention uses the Venturi principle. When the hot air blown by the circulating fan passes through the air duct which becomes narrower from wide, the textiles will be brought into the carefully designed corrugated plate air duct by the pressure difference. The textiles are completely driven by the airflow, and there is no need to use a lead belt to pull them during operation, which is convenient to operate. 4. The wave air duct of the present invention is a special wave flow channel design. The material is stainless steel to prevent rust and ensure a smooth working surface. The wave air duct allows the textiles to move freely under the blowing of hot air, allowing the textiles to creep freely. The strong airflow causes the textiles to shake violently in the wave plate air duct, so that the wool surface is fully erected, and the water molecules are vaporized by heat, reaching a tension-free and contact-free state. The drying and fluffy effects of the textiles meet customer satisfaction requirements; 5. The present invention is designed with upper air duct 1 and upper air duct 2, which utilizes a circulating fan to generate strong airflow hot air, so that it acts on the textiles just out of the curved air duct 2, so that the violently shaking fabrics can fall steadily on the conveyor belt; 6. The present invention is designed with a conveyor belt transmission, which can transport the textiles out of the oven without tension, thus ensuring the quality of the fabrics; 7. The present invention is designed with a dehumidification function. The wet textiles in the oven will generate a large amount of moisture during drying. Excessive moisture cannot be discharged, which will greatly reduce the drying effect and fluffiness of the textiles. The amount of moisture is large near the second curved air duct, so a high-power dehumidification fan is configured. The amount of moisture is small near the tail of the machine, so a relatively low-power dehumidification fan is configured, which saves electricity costs and meets customer needs.
