The invention provides an automatically adjusted cataplasm automatic production line, which comprises an automatic skew adjustment device and a spunlaced fabric unwinding device, wherein the automatic skew adjustment device comprises a base and an adjusting vehicle which is arranged on the base; the adjusting vehicle is connected to the base in a sliding mode by virtue of a guide rail which is fixedly arranged at the upper end of the base; an adjusting cylinder is arranged on the base, and a piston rod of the adjusting cylinder is hinged with the vehicle body; an opposite-side sensor is additionally fixedly connected to the lower part of the base; the spunlaced fabric unwinding device is detachably connected to a bearing base which is fixedly arranged on the vehicle body by virtue of a bearing; and a lower spunlaced fabric rolling shaft is connected to the part, close to the opposite-side sensor, of the lower side of the vehicle body in a rotatable mode by virtue of a mounted bearing. The automatically adjusted cataplasm automatic production line disclosed by the invention is simple to operate and conducive to production and maintenance. The coating width and thickness of a cataplasm body can be controlled, so that uniform coating is guaranteed; and meanwhile, the sticking amount of the cataplasm body on a cutter head can be reduced when a finished product is cut in a longitudinal direction. In addition, the position of a spunlaced fabric can be also automatically adjusted, so that product quality is guaranteed.
