AI Technical Summary
In printing equipment, the lack of a correction mechanism when feeding thick paper can cause slight skew during the feeding process, affecting the printing effect.
The paper is corrected by employing a correction mechanism and a detection mechanism. A laser edge detection sensor is used to detect the edge position of the paper in real time. A cylinder drives the correction roller to contact the guide roller, and a motor drives the correction roller to rotate synchronously to adjust the paper position and achieve the correction effect.
This effectively prevents paper from skewing when it is fed into the printing equipment, thus improving printing quality and efficiency.
