Non-woven fabric drying oven and protection mechanism thereof

The invention discloses a non-woven fabric drying oven and a protection mechanism thereof. The non-woven fabric drying oven comprises a drying oven body. A conveying line penetrating through the head and the tail of the drying oven body is arranged in the drying oven body and used for conveying non-woven fabric. A hot air device is further fixedly mounted at the top of the drying oven body and used for providing hot air into the drying oven body; the exhaust device is used for exhausting low-temperature airflow after heat exchange of the drying oven main body is completed out of the drying oven main body; the exhaust device also plays a role in fixing the non-woven fabric on the conveying line; the air inducing cover is directly located under the conveying belt, and a low-pressure area is formed under the conveying belt, so that the non-woven fabric can be firmly adsorbed on the conveying belt; and when the temperature information is continuously higher than the preset temperature value within the temperature
