[0019] The driven roller 4 has a long axis and a short axis extending from both ends, the long axis end is installed with a synchronous wheel 9 and a bearing flange 15, and the short axis side is installed with a bearing flange 15; the bearing flanges 15 at both ends of the driven roller 4 are rotatably connected to the driven roller 4 through bearings 16, and the bearing flanges 15 at both ends of the driven roller 4 are fixed to the brackets 12 located on both sides of the driven roller 4 by screws, and a spring rod 14 is installed under each bracket 12, and a spring 13 is arranged outside the spring rod 14; one end of the spring 13 is fixedly connected to the roller base 1, and the other end of the spring 13 is fixedly connected to the spring rod 14, and the spring generates an upward thrust to the bracket; the top of each bracket 12 is rotatably connected to the roller base 1 through the shaft A17 and the copper sleeve 18; the outer side of the shaft A17 is fixedly connected with a stopper 19;

[0021] When this roller conveyor for bar bundling is working:

[0022] The rod is transported forward in the roller baffle 2 through the transmission of multiple active rollers 3. When the rod passes through the driven roller 4, the rod presses the driven roller 4 downward, so that the upper surface of the driven roller 4 is close to the lower surface of the rod, thereby driving the driven roller 4 to rotate, and the number of rotations is transmitted to the encoder 11 through the synchronous wheel 9 and the synchronous belt 10, and the rod is sized by the calculation of the upper computer; the light curtain switch set at the far end of the rod in the roller baffle 2 checks and confirms whether the rod has been transported to the specified position; the encoder 11 receives the number of rotations and adds the transportation time to calculate the transportation speed of the rod in the roller, thereby controlling the transportation speed of the rod; when the rod completely passes through the driven roller 4, the driven roller 4 clamps the bottom of the roller baffle 2 through the thrust of the lower spring 13 to determine whether the rod has completely passed through the roller baffle 2.
