The invention discloses a spinning melt multi-stage filtering system for low-melting-point spandex fibers and a preparation method, and relates to the technical field of spandex fiber production. Discharge ends are fixedly arranged on the left side and the right side of the bottom of a first bearing cylinder. According to the spinning melt multi-stage filtering system for the low-melting-point spandex fibers and the preparation method, through mutual cooperation of the second bearing cylinders, the first bolts, the filtering cover assemblies and the connecting shafts, the number of the second bearing cylinders, the number of the filtering cover assemblies and the number of the connecting shafts can be flexibly increased or decreased according to needs, and then the filtering frequency is adjusted; through mutual cooperation of an arc-shaped brush, a sliding block, an inserting rod and a first spring, the inner walls of the rotating left filtering semicircular net cover and the rotating right filtering semicir
