[0070] S1: Place the pathological sample on the load slat, start the drive seat, adjust the lower end of the cutting blade and the upper surface of the load slat to be close to the upper surface of the load slat, and then start all the synchronously arranged motors in the traverse device to make the cutting blade approach the inner side, At the same time, the pathological sample is attached and moved, so that the left and right cutting blades are in contact with the left and right sides of the pathological sample;
[0071] S2: Start the light-sensing monitoring ring to automatically monitor the distance, that is, whether the left and right light-sensing monitoring rings move from the beginning to the end in the process of S1 is the same. If so, the left and right screw sleeves are in a normal state. Go to S3, if not, overhaul the traverse device and go to S1 again;
[0072] S3: According to the solid strength and flexibility of the pathological sample, select the appropriate tilt angle of the first transmission component, wherein the tilt angle adjustment rod is used for hinged joint, and the slice thickness value is preset, that is, after each slice is completed, the , the screw sleeve is driven by the motor to urge the cutting blade to approach inward, and the thickness value of the slice can be automatically changed again halfway;
[0073] S4: The value obtained by multiplying the moving speed of the conveyor belt driven by the drive shaft in the first transmission assembly by cosA, the moving speed of the driving shaft in the fourth conveying assembly is also cosA, which is consistent with the moving speed of the driving seat 1, so that the cutting blade moves down When the cut pathological section and the conveyor belt are in a relatively static state, A is the angle between the conveyor assembly 1 and the longitudinal plane.
