Background

The fully automatic pathological section dyeing machine used at present is mostly used for dyeing in a multi-tank dip dyeing mode. 1. The reagent loading process of the traditional pathological section dyeing machine is manually operated, so that the dyeing efficiency is improved by increasing the number of dyeing tanks of the same reagent, and the number of the dyeing tanks is far more than the types of the used reagents. In the using process, the replacement of the reagent is also carried out manually, and the replacement process is complicated; xylene is a common reagent, and the artificial replacement of the xylene has biosafety danger. 2. The reagent used by the existing full-automatic pathological section dyeing machine is always stored in the dyeing tank, all the dyeing tanks are always exposed in the air, and the dyeing tanks are only covered by covers when the machine is stopped, so that the stability of the reagent is difficult to ensure. 3. When traditional pathological section dyeing machine manual loading reagent, it is difficult to hold the reagent volume of adding accurately usually, and in the dyeing process, the reagent probably spills over the dyeing jar when slide carrier immerses, causes the pollution. 4. The dyeing machine aims at the defects that the traditional dyeing machine for adding liquid by using a pipeline generally has low liquid adding speed and incomplete liquid drainage, and meanwhile, after the dyeing machine is used for many times, residual stains on a dyeing tank and the pipeline are difficult to clean, so that the next use is influenced. 5. Aiming at the full-automatic dyeing machine which utilizes the pipeline to add liquid, when the pipeline valve is in fault or is blocked, if the fault or the blockage cannot be found in time, the pipeline can be directly damaged due to the rapid increase of the pipeline pressure. 6. The full-automatic dyeing effect has a certain relation with the concentration of a reagent, but the traditional full-automatic dyeing machine is carried out in each dyeing tank, so that the real-time detection of the concentration of all reagents is difficult, the traditional full-automatic dyeing machine estimates whether the dyeing concentration reaches a threshold value by calculating the dyeing times and needs to replace the reagent, and the dyeing process cannot be changed no matter how much the concentration of the reagent is, so that the dyeing effect cannot be controlled.
