Speed-controllable hot delivery roller device for production of bars with diameters of 18-40mm

The utility model discloses a speed-controllable hot delivery roller device for production of bars with the diameter of 18-40mm. A plurality of roller body driving motors are arranged below conveying roller bodies, close to one end of an inlet of a heating furnace, of a conveying roller way respectively and drive the roller bodies respectively, and meanwhile, rotating shafts of the driving motors are sleeved with pulse encoders and transmission control modules; after the rotating speed of each roller body close to the heating furnace is accurately measured, the pulse encoder is electrically connected with the transmission control module, so that the conveying speed of the red blank is effectively controlled, and the speed control precision of the red blank is improved. 本申请公开了一种直径18～40mm棒材生产用速度可控热送辊装置，在输送辊道靠近加热炉入口一端的输送辊体下方分别设置多个辊体驱动电机，分别对各辊体进行驱动，同时在驱动电机的转轴上套设脉冲编码器和传动控制模块，分别对靠近加热炉的各辊体的转动速度进行准确测量后，通过脉冲编码器与传动控制模块电连接，实现对红坯料输送速度的有效控制，提高红坯的速度控制精度。
