Slicer for deploying and detecting cutters based on negative feedback system

Abstract

The invention discloses a slicer for deploying and detecting cutters based on a negative feedback system. The slicer comprises a frame body, wherein a driving cavity is formed in the frame body, a driving block is installed on the top wall of the driving cavity in a sliding mode, a containing cavity with a leftward opening is formed in the driving block, a threaded shaft is rotatably installed on the top wall of the containing cavity, a threaded block is in threaded connection with the threaded shaft, a rotatable blocking plate is installed on the right side of the threaded block through a damping rotating shaft, a fastening plate fixed to the right side face of the threaded block is arranged on the lower side of the blocking plate, and four sets of fastening measuring devices which are completely the same in functional structure and are transversely arranged are installed on the front side face of the fastening plate. According to the slicer, whether foreign matters or hands exist in the machine or not is sensed through a sensor, so that the machine cannot injure people, even if a fault occurs, the machine cannot run, and the phenomenon that people are injured due to the fault of the machine is avoided.

Description

technical field [0001] The invention relates to the technical field of slicers, in particular to a slicer for adjusting and detecting knives based on a negative feedback system. Background technique [0002] A microtome is a machine that cuts thin and uniform slices of tissue. The tissue is supported by hard paraffin or other substances. Each cut is automatically advanced (towards the direction of the knife) by the slice thickness device to the required distance. The gradient of the thickness device is usually 1 micron. When cutting paraffin-embedded tissue, multiple slices are made due to the adhesion to the wax edge of the previous slice. The traditional machine has the following disadvantages: [0003] 1. The traditional machine is not convenient to measure the hardness of the material, which reduces the service life of the tool; [0004] 2. Traditional machines are inconvenient to clean and inspect the cutting tool, resulting in uneven and incomplete slices; [0005] ...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional machine is not convenient to measure the hardness of the material, which reduces the service life of the tool;

[0004] 2. Traditional machines are inconvenient to clean and inspect the cutting tool, resulting in uneven and incomplete slices;

[0005] 3. Traditional machines are not convenient for distributing knives according to materials with different hardness, and there is no complete control system to relatively control the cooperation between various mechanisms;

[0006] 4. The traditional machine is not convenient to protect the human body, and it is easy to cause the machine to start before the preparation process is completed, causing harm
