[0054] The working principle of the present invention is as follows: the shoe upper to be processed is placed on the mold 2, the second motor 41 drives the threaded rod 42 to rotate, the threaded sleeve 43 moves downward along the axial direction of the threaded rod 42, and drives the mounting plate 51 to move downward, the mounting frames 54 at both ends of the mounting plate 51 move downward, the flattening roller 56 at the bottom of the mounting frame 54 contacts the top of the mold 2, and rolls down along the side of the mold 2 under the action of resistance on both sides to flatten the shoe upper. In the process of moving downward and rolling, the rotating block 55 at the upper end of the mounting frame 54 rotates around the rotating column 53, and the torsion spring 57 between the two rotating blocks 55 applies elastic resistance to the mounting frame 54 rotating outward, so that the bottom of the mounting frame 54 The flattening roller 56 fits tightly against the shoe upper on the mold 2, better flattens the shoe upper and flattens wrinkles. After the flattening roller 56 moves down to the bottom of the mold 2, the first motor 66 drives the gear 65 to rotate, and the racks 64 on both sides of the gear 65 move to drive the first fixed plates 61 at both ends to move relative to each other. The second fixed plate 62 first contacts the bottom of the shoe upper and fixes the shoe upper through the compression force of the spring 610. The toothed block 62 located below the second fixed plate 62 can better apply thrust to the bottom of the shoe upper to fix it, and the flattening roller 56 is engaged with the placement groove 611, which will not cause resistance to the first fixed plate 61. After the fixation is completed, the shoe upper can be processed.
