Leveling device for plastic film production

The flattening device for plastic film production comprises a rack, the flattening device comprises an A-shaped frame and flattening rollers, the A-shaped frame comprises two frames which are symmetrically arranged along a vertical line, each frame comprises an upper frame and a lower frame which are of a square structure, and a plurality of extrusion rollers which are arranged in parallel are arranged in the upper frame and the lower frame respectively; the bottoms of the two lower frames are provided with two parallel auxiliary frames, and each auxiliary frame is provided with an auxiliary extrusion roller perpendicular to the extrusion rollers. On the premise that the requirement for the included angle of the propeller strut is met, the height of the propeller strut can be reduced as much as possible through the arrangement of the upper frame and the lower frame, the equipment manufacturing difficulty is reduced, the number of extrusion rollers can be larger than that of a conventional propeller strut, and
