At this time, the surface of the limit gear 61 is engaged with the surfaces of the limit teeth 62 on both sides at the same time, and the adjustment block 41 cannot move further. At the same time, the retraction rod 91 and the control column 44 will extend under the action of the spring. At this time, the groove on the surface of the control column 44 will contact the surface of the rotating rod 43. The rotation of the rotating rod 43 will drive the control column 44 to rotate, thereby prompting the transfer gear 45 to rotate. At this time, all the rolling rollers 2 will be driven to rotate through the reversing component 8 and the synchronous component 5, and the billet can be placed on the conveyor belt surface to start rolling the billet.
