The front end of the driving conveying roller 1 positioned on the feeding side and the rear end of the driving conveying roller 1 positioned on the discharging side of the press machine are respectively provided with a plurality of bearing rollers 2 in parallel, the bearing rollers 2 are arranged on the side frames, the side frames are mounting frames positioned on the side surfaces of the press machine, in order to avoid the interference of the drawing, the side frames are not shown in the drawing, and how to mount the bearing rollers 2 on the side frames is the common knowledge which should be possessed by the skilled person. The bearing roller 2 does not rotate actively with the bearing plate 0, but rotates along with the plate 0 in the moving process, so that the function of changing sliding friction into rolling friction is achieved. In order to improve the conveying stability, it is preferable that a driven conveying roller 35 is arranged above the driving conveying roller 1, and the driven conveying roller 35 is driven by the plate 0 instead of being driven by the same bearing roller 2, and mainly plays a role in vertically limiting the plate 0. The plate material 0 is clamped between the driving conveying roller 1 and the driven conveying roller 35, and the driven conveying roller 35 is installed on a side frame.

The two ends of the roller 36 close to the end disc 37 are provided with a thread section 39 with external threads on the circumferential surface. The threaded section 39 is externally sleeved with a cylindrical adjusting cap 40, and the adjusting cap 40 and the threaded section 39 form threaded fit. The circumferential surface of one end of the adjusting cap 40 facing the center of the roller body 36 is provided with a circular limiting brim 41. The distance between the limiting edges 41 of the two adjusting caps 40 actually corresponds to the width of the plate 0.
