Circular knife setting and adjusting mechanical structure

The invention discloses a mechanical structure for setting and adjusting a circular knife. The mechanical structure comprises an upper knife workpiece, a lower knife workpiece and an upper knife control workpiece module, the upper cutter control workpiece module is in transmission connection with an upper cutter workpiece, and the upper cutter workpiece is driven by the upper cutter control workpiece module to turn over and swing; the upper cutter workpiece is in transmission connection with the lower cutter workpiece; the upper cutter control workpiece module is provided with a side pressure measuring assembly and an occlusion depth measuring assembly. The occlusion depth measuring assembly is used for measuring occlusion depth data between the upper cutter workpiece and the lower cutter workpiece; the problem that current actual occlusion depth data and the lateral pressure numerical value are difficult to quantify is solved, the numerical value of the occlusion depth and the numerical value of the lateral
