[0037] Working principle:

[0038] First, the steel plate to be cut is placed on the steel plate placing table 10, and then pushed onto the adjusting roller, and then the steel plate is transported forward during the rotation of the adjusting roller;

[0039] During the cutting process, first, when the output shaft of the driving motor 6 rotates, it drives the driving shaft 21 to rotate, and the driving shaft 21 drives the adjusting rod 25 to rotate. At the same time, the connecting plate on the adjusting rod is fixedly connected to the adjusting roller 2, so it can drive the adjusting roller 2 to rotate; the frame 1 is also provided with a detection component for detecting whether the steel plate is offset. The photoelectric transmitter continuously sends a signal to the photoelectric receiving sensor, which is convenient for the sensor to receive. When the steel plate is offset and blocks the signal, the offset signal will be transmitted to the central processing unit. At the same time, the central processing unit controls the deviation correction telescopic motor 23 to start. When the telescopic rod of the deviation correction telescopic motor 23 is extended or shortened, it drives the adjusting rod 25 to move left and right, and then drives the adjusting roller 2 to move left and right, and then corrects the deviation.

[0040] When the steel plate is on the cutting table 91 and moves to the position to be cut, the drive motor stops rotating, the steel plate stops being transported, and the suction cup electromagnet is energized, and the suction cup electromagnet tightly absorbs the steel plate; then the cutting mechanism cuts the steel plate. After the cutting is completed, the suction cup electromagnet is powered off, the suction cup electromagnet is separated from the steel plate, the drive motor is started, and the cut steel plate continues to be transported forward, and the cut steel plate is transported to the receiving table at the rear end of the frame.

[0041] In the above embodiments and working processes, the anti-deviation rollers can be used to correct slight deviations in real time. If the deviation continues, the correction telescopic motor will be activated to correct the deviation at the source; the detection components can facilitate real-time monitoring of the transportation process of the steel plate and transmit the deviation signal to the central processor for real-time processing; the balls and limit slides can facilitate smooth movement when adjusting the position of the rollers without jamming; the mounting holes are provided on the frame and fixed with the fastening screws, which facilitates the installation and adjustment of the detection bracket; the suction cup electromagnet and the corresponding suction cup electromagnet mounting tube can facilitate the fixed limit of the steel plate, thereby avoiding the deviation of the steel plate during the cutting process.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
