Laundry rack driving module winding tightness detection device and working method thereof

The invention relates to the technical field of clothes hangers, in particular to a clothes hanger driving module winding tightness detection device and a working method thereof. A to-be-wound clothesline is unwound through the arranged pay-off roller, and the unwound clothesline is straightened in advance through the guide roller, so that the clothesline entering the tightness detection device is in a straight state, and the clothesline entering the tightness detection device is pressed on a pressure sensor; therefore, whether the clothesline is in a normal tightening state or an over-tightening or over-loosening state is judged according to the pressure data acquired by the pressure sensor, and meanwhile, the tightness detection assembly can perform active adjustment when detecting that the clothesline is in the over-tightening or over-loosening state, so that the clothesline on the winding station is always kept in the normal tightening state, and the clothes drying efficiency is improved.
