Printing machine with smoothing assembly

The printing machine comprises a main body, a flat plate is attached to the top of the main body, limiting plates are arranged on the two sides of the upper portion of the flat plate, track pads are arranged on the sides, close to the main body, of the limiting plates, and a translation assembly is arranged on the top of the flat plate; the translation assembly comprises a cross rod, a convex edge, a first support and a double-end stud; the two ends of the transverse rod are rotationally connected with first supports, the bottoms of the first supports are fixedly connected with the top of the main body, and the outer wall of the transverse rod sequentially penetrates through the two limiting plates. The utility model relates to the technical field of printing machines, in particular to a printing machine with a flattening assembly, which can flatten materials to be printed from the middle to the two sides, is uniform in flattening force, large in flattening area, more complete in flattening and better in effe
