The cutter is fixed on the top of the machine body. In order to prevent the cutter from destroying the shape of the stacked liner paper when cutting the liner paper, a hydraulic cylinder is generally used to drive the pressure plate to move downward so that the pressure plate presses the liner paper. However, the pressing force of the existing pressure plate is inconvenient to adjust, and it is easy for the pressure plate to have low fixing stability on the liner paper due to too small a pressing force or to damage the liner paper due to too large a pressing force of the pressure plate. Therefore, it is necessary to design and transform the tension adjustment mechanism of the liner paper slitting machine to effectively prevent the phenomenon of inconvenient adjustment.
