The invention belongs to the technical field of plate film covering, and relates to a film covering device for PP plate production, the film covering device comprises a
workbench, transmission rollers, side frames, a mounting seat and a winding shaft, the multiple transmission rollers are uniformly and rotatably connected to the upper portion of the
workbench at intervals, the side frames are connected to the two sides of the top of the
workbench, and the mounting seat is connected to the upper portions of the side frames; a winding shaft is installed between the two installation bases, the winding device further comprises a pressing roller, a sliding shaft, a first elastic piece, a
cut-off mechanism and a
cutting mechanism, the sliding shaft is connected between the lower portions of the two side frames in a sliding mode, the pressing roller is connected to the sliding shaft in a rotating mode, the first elastic piece is connected between the sliding shaft and the side frames, and the
cut-off mechanism and the
cutting mechanism are arranged on the side frames. According to the film pasting device, after film pasting of the PP plate is completed, redundant excess materials on the two sides of the PP plate are
cut through the
cutting knife, and during cutting, a covering film on the PP plate can be pressed through the lower pressing frame, so that the covering film is prevented from being wrinkled, and the yield during film pasting of the PP plate is guaranteed.
