[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1-4 A hydraulic cover plate device for finished product roller conveyor at the exit of a rolling mill includes a first frame 1 and a second frame 9. Two first mounting plates 6 are symmetrically fixed on the first frame 1, and two second mounting plates 10 are symmetrically fixed on the second frame 9. A first conveying assembly is installed between the two first mounting plates 6, and a second conveying assembly is installed between the two second mounting plates 10. A guiding mechanism is installed above the first conveying assembly, and a correction mechanism is installed above the second conveying assembly.

[0022] The guiding mechanism includes two guide plates 7. A connecting seat 18 is fixed on one side of the guide plate 7. A connecting rod 19 is fixed on the connecting seat 18. A U-shaped frame 17 is fixed on one side of the first mounting plate 6. One end of the connecting rod 19 is inserted into the middle of the U-shaped frame 17, and nuts 21 are screwed onto both the inner and outer sides of the connecting rod 19 on the U-shaped frame 17.

[0023] The first conveying assembly includes a first conveying roller 5 rotatably mounted between two first mounting plates 6 via bearings. Each of the first mounting plates 6 has a number of first servo motors 2 that are equidistant from one side, the same number as the first conveying roller 5. The output end of each first servo motor 2 is connected to one end of a first conveying roller 5.

[0024] The second conveying assembly includes a second conveying roller 22 rotatably mounted between two second mounting plates 10 via bearings. Each of the second mounting plates 10 has a number of second servo motors 23 that are equidistant from one side, the same number as the second conveying rollers 22. The output end of each second servo motor 23 is connected to one end of a second conveying roller 22.

[0025] The calibration mechanism includes two support blocks 8 fixed on opposite sides of two second mounting plates 10. A rotating plate 3 is rotatably mounted on each of the two support blocks 8. An installation port is provided at the end of each rotating plate 3 away from the support block 8. A first guide wheel 13 is rotatably mounted at the installation port via a bearing. A hydraulic push rod 4 is mounted on each of the two second mounting plates 10. A connecting block 12 is fixed at the opposite end of each of the two hydraulic push rods 4. A toggle rod 15 is fixed on each of the two connecting blocks 12. A movable groove 16 is provided on one side of each of the two rotating plates 3. A strip hole 14 is provided at both the upper and lower ends of the movable groove 16 on the rotating plate 3. The upper and lower ends of the toggle rod 15 are respectively slidably engaged with the strip holes 14 at the upper and lower ends of the rotating plate 3. The two hydraulic push rods 4 are externally connected to a synchronizer through a hydraulic station. When the hydraulic push rods 4 extend or retract, they drive the toggle rod 15 to slide at the strip hole 14, thereby driving the rotating plate 3 to rotate.

[0026] Both guide plates 7 are provided with fixing holes, and a second guide wheel 20 is installed at the fixing holes.

[0027] The first frame 1 and the second frame 9 are bolted onto the external support of the rolling mill. The first frame 1 is located at the exit of the rolling mill, and the second frame 9 is located behind the first frame 1. The number of second frames 9 is installed in groups according to the length of the rolled piece. The first servo motor 2 and the second servo motor 23 are controlled by an external controller, which causes the first conveying roller 5 and the second conveying roller 22 to rotate. After the rolled piece comes out of the rolling mill, it enters between two guide plates 7. The rotation of the first conveying roller 5 realizes the conveying of the rolled piece. The second guide wheels 20 on the two guide plates 7 provide rolling support to the sides of the rolled piece. When the rolled piece moves onto the second conveying roller 22, the rotation of the second conveying roller 22 continues to convey the rolled piece. The external controller synchronously controls the extension and retraction of two hydraulic push rods 4, which drives the two rotating plates 3 to rotate synchronously to adjust the distance between the two first guide wheels 13. The rolled piece can pass normally within the distance, ensuring that the rolled piece does not bend or twist.

[0028] Example 2 is an optimization based on Example 1, specifically:

[0029] Both guide plates 7 have bent sections 11 at their ends, and the two bent sections 11 are combined to form a flared mouth.

[0030] When the rolled piece comes out of the rolling mill, the design of the flared mouth helps guide the rolled piece to smoothly enter between the two guide plates 7.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
