Background
The linen folding machine is mainly suitable for laundry places of hotels, hospitals and large washing plants, and is used for selecting corresponding programs for folding and screening linen such as washed and ironed sheets, tablecloths, quilt covers, pillowcase and towels. Generally, each folding of the linen is performed independently by the linen folding machine, the linen is folded for five times by five folding mechanisms, the folded linen is conveyed to the sorting and stacking mechanism through the conveying belt for sorting, generally, because the folding mechanism in the linen folding machine is only responsible for the folding of the linen and does not perform preliminary screening or recognition on the linen, the folded linen conveyed to the sorting and stacking mechanism cannot be finely sorted, for example, the actual length difference of the linen in certain specifications is small or even no difference, for example, the length difference of the linen in 1.2 meters and 1.8 meters is only a few centimeters after being folded by the folding machine. Therefore, great difficulty is brought to subsequent linen classification work, when the actual measured value has great deviation from the actual preset length value of linen, errors of stacking positions occur, and great loss is brought to field efficiency and asset management.
