Cable shaft cylinder plate preparation equipment

The invention relates to cable shaft barrel plate preparation equipment which comprises a rack, a moving structure, a polishing assembly and a spring. Firstly, a rectangular plate is placed on a bearing plate, a piston rod of a first air cylinder abuts against the rectangular plate, driving pieces drive a lead screw to rotate, the lead screw drives a bearing plate to move along a guide rod in the rotating state, and after the bearing plate drives the rectangular plate to make contact with a gravel column of a left grinding piece and a gravel column of a right grinding piece, the two driving pieces drive the gravel columns to rotate correspondingly; in the rotating state, the gravel column makes contact with the side edge of the rectangular plate, the lead screw drives the bearing plate to continue to move along the guide rod, the two ends of a spring are fixedly connected with the two connecting rods correspondingly, the gravel column makes contact with the side edge of the rectangular plate in the rotating s
