The columnar raw material sawed by the sawing machine is conveyed to the detection platform 1 through the conveying belt 2 to be detected in a mode that the axial direction of the columnar raw material is kept perpendicular to the conveying direction of the conveying belt 2, so that whether the columnar raw material needs secondary grinding or not is judged. When the columnar raw material is conveyed to the detection platform 1, the columnar raw material is fixed on the detection platform 1 by the fixing mechanism 3, and then the columnar far-away burr condition is detected by the detection mechanism 4.
Referring to fig. 2, a limit groove 31 is formed in one end, close to the conveyor belt 2, of the upper end surface of the detection platform 1, the limit groove 31 is a trapezoidal groove, and the size of an opening of the limit groove 31 is gradually reduced along the forming direction. The extending direction of the limiting groove 31 is parallel to the length direction of the detection platform 1, and the center of the limiting groove 31 in the length direction is corresponding to the position of the conveyor belt 2, so that the columnar raw material can roll into the limiting groove 31 under the action of inertia and self gravity after being conveyed from the conveyor belt 2 to the detection platform 1.
Referring to fig. 3, the folded plate 32 includes a rotating plate 323 and a fixing plate 321, the rotating plate 323 and the fixing plate 321 are rectangular plates, and the length directions of the rotating plate 323 and the fixing plate 321 are both parallel to the length direction of the testing platform 1.

The guide rail 621 is a trapezoidal rail, the guide rail 621 is connected with a rotating support 622 in a sliding manner, the sliding support can be longitudinally prevented from slipping off and can slip on the guide rail 621 along the length direction of the guide rail 621, the rotating support 622 is connected with a rotating shaft 623 in a rotating manner, and the axial direction of the rotating shaft 623 is parallel to the width direction of the detection platform 1.
At this time, the rotating support 622 is driven to move towards the nondestructive channel 51 on the guide rail 621, and then the sliding rail 624 is driven to move towards the nondestructive channel 51, under the matching of the rail wall of the sliding rail 624 and the sliding bar 625, when the sliding rail 624 moves towards the nondestructive channel 51, the sliding rail 624 simultaneously rotates on the rotating support 622, and the sliding bar 625 moves towards one end of the sliding rail 624 close to the nondestructive channel 51, and then the detection platform 1 fixedly connected with the sliding bar 625 is pulled to turn over by taking the support shaft close to the nondestructive channel 51 as an axis, so as to guide the columnar raw material into the nondestructive channel 51.
Similarly, the rotating support 622 is driven to move toward the polishing channel 52 on the guide rail 621, and the detecting platform 1 can be driven to turn around the supporting shaft near the polishing channel 52, which is not described herein again. In order to drive the rotating support 622 to move on the guide rail 621, a linear driving member is further disposed on the guide rail 621.

The driving motor 626 drives the screw rod to rotate, so as to drive the rotating support 622 to move in the guide rail 621 along the length direction of the guide rail 621. The driving motor 626 is also electrically connected to the controller, so that the worker controls the driving motor 626 to turn the detecting platform 1 over to sieve the columnar material.
Further, due to the irregular shape and position of the burrs, part of the burrs may be folded to the side wall of the cylindrical raw material, so that the detection platform 1 is provided with an end wall polishing lane 521 and a side wall polishing lane 522 on the side of the polishing channel 52 away from the nondestructive channel 51, and is provided with a splitter 7 for guiding the cylindrical raw material to the end wall polishing lane 521/side wall polishing lane 522.

Meanwhile, the shunt motor 73 is electrically connected with the controller, so that the position of the shunt plate 71 can be rapidly changed through the matching of the controller and the shunt motor 73 after workers judge the burr condition on the columnar raw material.
Furthermore, because the columnar raw material is guided to the end wall polishing lane 521/side wall polishing lane 522 under the action of the flow distribution plate 71 and collides with the flow distribution plate 71, in order to prolong the service life of the flow distribution plate 71 and to avoid the columnar raw material from being damaged during collision, glue layers 72 are fixedly connected to both sides of the surface of the flow distribution plate 71 so as to reduce the impact force when the columnar raw material collides with the flow distribution plate 71.
Meanwhile, no matter the columnar raw material is shunted to the lossless channel 51 or the polishing channel 52, when the columnar raw material slides out of the fixing plate 321 of the folded plate 32, the pressure applied to the pressure sensor is reduced, the pressure is triggered again, the controller is driven to close the electromagnet, after the electromagnet is closed, the folded plate 32 is reset under the action of the torsion spring, returns to the initial position, and waits for the next columnar raw material to be transferred to the limiting groove 31 for detection.
