[0017] Please see Figure 1 , Figure 2 and Figure 3A centering frame for steel plate trimming is installed on a conveyor roller conveyor 10 in front of the trimming station. It includes a base frame 20 and two sets of centering units 30. The base frame 20 is installed on the top of the conveyor roller conveyor 10 along the steel plate conveying direction, and has two guide rails 21 extending towards the central axis of the conveyor roller conveyor 10, one in front of the other on each side. The two sets of centering units 30 are correspondingly arranged on both sides of the conveyor roller conveyor 10, and each centering unit 30 includes a fixed base 31 connected to the outside of the conveyor roller conveyor 10 and a centering drive mounted on the upper part of the fixed base 31. The centering roller 33 is hinged to the telescopic rod of the centering drive cylinder 32. The telescopic rod of the centering drive cylinder 32 is set towards the central axis of the conveyor roller table 10. Each centering roller 33 is set between two guide rails 21 on the same side. The centering roller 33 is provided with a slide block 331 at the bottom that matches the guide rail 21, so that the telescopic rod of the centering drive cylinder 32 can extend and retract, which can drive the centering roller 33 to move forward and backward along the two guide rails 21 on the same side towards the central axis of the conveyor roller table 10. The centering rollers 33 of the two sets of centering units 30 are used to center the steel plate in front of the trimming station.

[0018] Furthermore, in this embodiment, the conveying roller conveyor 10 includes two support frames 11 arranged opposite to each other and a plurality of conveying rollers 12 rotatably arranged above the two support frames 11 at intervals along the steel plate conveying direction. One end of each conveying roller 12 is correspondingly arranged on the top of a support frame 11 and a bearing seat 121 connected to the top of the support frame 11 is provided thereon, so that the top of the plurality of conveying rollers 12 forms a conveying surface for conveying the steel plate.

[0019] Furthermore, in this embodiment, the bottom frame 20 is disposed between the tops of the two support frames 11, and its top surface is flush with the top surfaces of the two support frames 11. Each support frame 11 has a guide rail 21 arranged one in front of the other on its top surface. Each guide rail 21 is connected to the top surface of the support frame 11 at one end and to the top surface of the bottom frame 20 at the other end.

[0020] Furthermore, in this embodiment, the guide rail 21 is formed with a reinforcing section 211 extending to the outside of the support frame 11. The reinforcing section 211 is connected to the fixed seat 31 to achieve a reinforcing effect.

[0021] Furthermore, in this embodiment, the centering roller 33 includes a hinge seat 332 that is hinged to the telescopic rod of the central drive cylinder and a roller body 333 that is rotatably disposed on the side of the hinge seat 332 facing the central axis of the conveyor roller table 10. The slide 331 is installed at the bottom of the hinge seat 332.

[0022] Furthermore, in this embodiment, after the centering rollers 33 of the two sets of centering units 30 are installed, their roller bodies 333 are horizontal in the same position and perpendicular to the central axis of the conveyor roller table 10.

[0023] Furthermore, in this embodiment, the fixed seat 31 includes a main seat 311 disposed on the outside of the support frame 11 and a cylinder mounting seat 312 mounted on the top surface of the main seat 311. The top surface of the main seat 311 is flush with the top surface of the support frame 11, and the centering drive cylinder 32 is mounted on the cylinder mounting seat 312.

[0024] Understandably, the method of using the centering frame for steel plate trimming according to this utility model is as follows: Based on the trimming position of the steel plate, the position of the centering rollers 33 of the two sets of centering units 30 is adjusted by extending and retracting the telescopic rod of the centering drive cylinder 32, so that the center of the steel plate before entering the trimming station is parallel or coincident with the central axis of the conveying roller table 10, thereby ensuring the accuracy of trimming.

[0025] In summary, the centering frame for steel plate trimming of this utility model, through the cooperation between the bottom frame 20 and two sets of centering units 30, can center the steel plate before it enters the trimming station, thus ensuring the accuracy of steel plate trimming.

[0026] Any combination of different embodiments of this utility model, provided it does not violate the inventive concept of this utility model, shall be considered as the disclosure of this utility model; any simple modifications to the technical solution and any combination of different embodiments within the scope of the inventive concept of this utility model, without violating the inventive concept of this utility model, shall be within the protection scope of this utility model.
