The invention relates to an ABS plastic recycling and cleaning re-production production line. The ABS plastic recycling and cleaning re-production production line comprises a feeding machine, a magnetic separation device, a first cleaning tank, a first dehydration and transfer mechanism, a spraying mechanism, a first conveying mechanism, a second cleaning tank, a second dehydration and transfer mechanism, a drying mechanism, a first plastic cap separation device, a second plastic cap separation device, a second conveying mechanism and a color sorting device from left to right. According to theproduction line, by arranging the first dehydration and transfer mechanism, the spraying mechanism and the first conveying mechanism between the first cleaning tank and the second cleaning tank, cleaning liquid carried with materials from the first cleaning tank is thoroughly removed from the materials which are cleaned for the first time through the first dehydration and transfer mechanism, thenremaining chemicals on the surfaces of the materials are removed through the spraying mechanism, afterwards, the materials are transported into the second cleaning tank through the first conveying mechanism, and the situation that the chemicals on the surfaces of the materials which are cleaned for the first time contaminate the second cleaning tank, and the cleaning and separating effect at thesecond time is influenced accordingly is effectively avoided.
