[0003] For example, the utility model patent with patent announcement number CN214030597U discloses a sheet material driving roller, including a left side plate and a right side plate, wherein a central shaft rod is inserted and fixedly installed in the center of the left side plate and the right side plate, and the left side plate and the right side plate are respectively provided with a plurality of radial long hollow grooves centered on the central shaft rod, and a driving rod is connected between the long hollow grooves of the left side plate and the right side plate, and external threads are respectively provided at both ends of the driving rod, and the ends of the driving rod are inserted into the long hollow grooves and fixed by nuts.

[0004] When the sheet driving roller is used and the spacing between the driving rods needs to be adjusted according to the size of the product, the nuts at both ends of the driving rod need to be loosened, and then the driving rod is moved to the corresponding position and the nuts are tightened to position the driving rod. The above operations are then performed on other driving rods in turn, so that the distance from each driving rod to the central shaft is consistent, thereby achieving the spacing adjustment between the driving rods.

[0005] When moving the driving rod, the distance between the driving rod and the central axis rod needs to be judged by the staff through visual inspection, which is highly subjective and may cause differences in the distance between the adjusted position of each driving rod and the central axis rod, thereby causing inconsistent spacing between the driving rods. As a result, during the production process, the driving rod cannot be accurately inserted between the semi-finished sheets to push the semi-finished sheets to the feeder, affecting the processing efficiency of the product and needs to be improved.
