The invention relates to a lining paper directional discharging device and an
isolator, and the lining paper directional discharging device comprises a conveying platform which is arranged in the
isolator and comprises a first end and a second end opposite to the first end, and the first end is used for bearing lining paper to be discharged; the pushing mechanism is arranged in the
isolator and is configured to apply a pushing force for moving from the first end to the second end to the lining paper arranged on the conveying platform; and the closing-in guide
assembly is mounted at the exhaust port of the isolator. According to the lining paper directional discharging device and the isolator, the lining paper is actively pushed by arranging the pushing mechanism, and the lining paper is directionally discharged from the
waste paper outlet with the controlled
caliber in cooperation with the closing-up guide
assembly, so that the problem that in the prior art, the lining paper is discharged from the
waste paper outlet with the controlled
caliber is solved; the problems that a preset
positive pressure environment in the isolator is out of control and external pollutants invade due to the fact that
waste paper is discharged through a large opening are solved, and meanwhile clamping stagnation possibly occurring in the discharging process of the lining paper easy to curl is overcome.
