[0041] By setting the pressure roller 4 located at the first position and the second position so that the spacing between them and the conveying roller 2 is greater than or equal to D and less than 2D, the overlapping steel bars 100 cannot continue to be conveyed forward due to the obstruction of the pressure roller 4. By setting the pressure roller 4 to float between the first position and the second position, the pressure roller 4 can apply a downward pressure to the steel bars located in the upper layer during the floating process, thereby pressing the steel bars 100 located in the upper layer down to be flush with the steel bars 100 in the lower layer, thereby realizing automatic sorting of the overlapping steel bars 100, which has the advantages of high efficiency, safety and reliability and low labor intensity.

[0042] Specifically, refer to Figures 1 to 7A support seat 6 is fixedly arranged on the conveying frame 1, and a pivot hole 61 and a first arc hole 62 and a second arc hole 63 are provided on the support seat 6. An adjusting rotating seat 7 is arranged on the side of the support seat 6 close to the nip roller 4, and the adjusting rotating seat 7 is pivotally connected to the pivot hole 61 through an adjusting shaft 71, and a fixing hole 72 arranged opposite to the first arc hole 62 is provided on the adjusting rotating seat 7.

A first fixing rod 10 is fixedly arranged on the adjusting rotating seat 7, and the first fixing rod 10 passes through the second arc hole 63 to the side of the supporting seat 6 away from the adjusting rotating seat 7, and a second fixing rod 11 is fixedly arranged on the supporting seat 6, and the first fixing rod 10 and the second fixing rod 11 are spaced apart along the extending direction of the second arc hole 63, and an elastic member 9 is connected between the first fixing rod 10 and the second fixing rod 11. Preferably, the elastic member 9 is a tension spring. Through the above arrangement, the nip roller 4 can be moved from the first position to the second position under the action of an external force, and can be moved from the second position to the first position under the action of the restoring force of the elastic member 9.

[0043] Initially, refer to Figure 1 , the nip roller shaft 5 is located at the lower end of the first arc hole 62 (ie, at the first position), and the first fixing rod 10 is located at the upper end of the second arc hole 63, referring to Figures 8 to 10 When the overlapping steel bars 100 are conveyed to the pressing roller 4 along the conveying roller 2, the upper steel bars 100 will apply a lifting force to the pressing roller 4, driving the pressing roller shaft 5 and the adjusting rotating seat 7 to rotate around the adjusting shaft 71, and the pressing roller shaft 5 will move upward along the first arc hole 62 to the second position. At the same time, the first fixing rod 10 will move downward along the second arc hole 63, and the elastic member 9 will be stretched.
