The device for detecting and marking rod-shaped materials according to claim 1, wherein: The structure of a single lifting support mechanism (3) is as follows: it comprises a mounting plate (301) fixed on a main frame (10); a plurality of parallel lifting rails (303) are mounted on the front of the mounting plate (301); a plurality of lifting sliders (304) are mounted on the single lifting rail (303); a lifting seat (302) is fixed on the lifting slider (304); a lift (310) is mounted on the main frame (10) below the lifting seat (302); a power input end of the lift (310) is connected to a corresponding second connecting shaft (7); an output end of the lift (310) is connected to the lifting seat (302); when the second connecting shaft (7) rotates, it provides driving force for the lift (310), so that the lift (310) drives the lifting seat (302) to perform a linear motion of rising or falling in a vertical direction; The top of the lifting seat (302) is equipped with a first transmission wheel (305) and a roller group. The roller group includes an active roller (308) and a driven roller (309) arranged at intervals. The end of the active roller (308) is equipped with a second transmission wheel (307). A transmission chain (306) is installed between the first transmission wheel (305) and the second transmission wheel (307). The first transmission wheel (305) is connected to the corresponding first connecting shaft (6). When the first connecting shaft (6) rotates, it drives the first transmission wheel (305) to rotate, thereby driving the active roller (308) to rotate through the transmission chain (306) and the second transmission wheel (307), and then driving the workpiece (11) on the roller group to rotate.

5. The detection and marking device for rod-shaped materials according to claim 1, characterized in that: The structure of the first chain transmission mechanism (8) is as follows: it includes a first driving wheel (801) connected to the output end of the rotary drive motor (4), and a first driven wheel (803) installed at the end of the first connecting shaft (6), and a first chain (802) is installed between the first driven wheel (803) and the first driving wheel (801).

6. The device for detecting and marking rod-shaped materials according to claim 1, wherein: The structure of the second chain transmission mechanism (9) is as follows: comprising a transmission shaft (904), wherein a second driven wheel (905) and a third driven wheel (906) are installed at the shaft end of the transmission shaft (904) at intervals; The invention also includes a second driving wheel (901) connected to the output end of the lifting drive motor (5), and a fourth driven wheel (907) installed at the end of the second connecting shaft (7). A second chain (902) is installed between the second driving wheel (901) and the second driven wheel (905), and a third chain (903) is installed between the fourth driven wheel (907) and the third driven wheel (906).

7. The device for detecting and marking rod-shaped materials according to claim 1, wherein: Two adjacent first connecting shafts (6) and two adjacent second connecting shafts (7) are connected via couplings.
