The invention discloses a calender for a PVC film processing process. The calender comprises a frame, a calendering device arranged on the frame and a scraping device arranged at the front part of theframe. The calendering device comprises a first pressing roller, a second pressing roller arranged on one side of the first pressing roller, a third pressing roller arranged below the second pressingroller, a fourth pressing roller arranged below the third pressing roller, first connecting blocks arranged on the left side and the right side of the first pressing roller and the second pressing roller, second connecting blocks arranged on the left side and the right side of the third pressing roller, third connecting blocks arranged on the left side and the right side of the fourth pressing roller, transmission devices arranged on the connecting blocks, a discharging device arranged on the first pressing roller, and the scraping device arranged at the front part of the fourth pressing roller. According to the calender, intermittent blanking is carried out through a blanking trough, so that the blanking is more uniform, two sides of a PVC film are the same in thickness, the PVC film isrolled and flattened through a flattening device, the consistent thickness can be realized by the scraping device, meanwhile, scraped materials can be recycled, and thus resources are saved.
