[0031] A contour positioning mechanism 5 for correcting and positioning the workpiece position is arranged above the discharge side of the roller frame 2, and a lifting mechanism 6 for lifting the workpiece after position correction is arranged below;

[0032] The profiling positioning mechanism 5 includes a front profiling positioning plate 51, a right profiling positioning component 52 and a left profiling positioning component 53 connected to the roller frame 2.
