Adaptive flattening device for edge folding of high-grade printing color box

The utility model relates to a box body edge folding process, in particular to an adaptive flattening device for edge folding of a high-grade printing color box. The carton flattening device comprises an installation part, a driving assembly and a flattening part, the flattening part and the driving assembly are connected through a ball hinge, the driving assembly drives the flattening part to flatten the surface of a carton, due to the ball hinge, the positions, with different heights, of the surface of the carton can bear pressure, and finally the parts with different heights are attached and flattened. 本实用新型申请涉及盒体折边工艺，尤其设计一种用于高档印刷彩盒折边的适配型压平装置。其包括：安装件、驱动组件和压平件，其中压平件和驱动组件通过球铰接连接，驱动组件驱动压平件压平纸箱表面，由于球铰接，纸箱表面高度不同的地方均能受到压力，最终表现为高度不同的部分贴合压平。
