The invention discloses an automatic knife
positioning system with dynamic running state display and timing control of a freezing
microtome and four-point
refrigeration, which comprises a case which has a
freezing chamber arranged inside and four refrigerating points of a freezing table, a freezing head and a freezing knife, etc., and an automatic knife positioning distance
detector is arranged at the
leading edge of the freezing knife;
software of the automatic knife
positioning system includes a timing controlling program and a dynamic displaying program; the automatic knife
positioning system has the functions including the control that the
machine halt and startup interval lies in 5 minutes or more, the control that the complete
machine automatically shuts down after running for 8 hours, the control that a compressor A automatically enters a resting state, the temperature setting of the refrigerating points, the temperature, illumination and
ultraviolet disinfection control of the freezing table, the
freezing chamber, the freezing head and the freezing knife, the automatic knife positioning and deviation calibration, and the
countdown time display. The automatic knife positioning
system has ingenious conception, reasonable design and dynamic hardware identification display of the complete
machine, adopts the parts of excellent materials and famous foreign brands as well as precise
processing and
assembly of key parts, can be freely used after startup in any time, overcomes the disadvantages of large
power consumption and long
waiting time, has perfect, stable and reliable performance and easy operations, and is applicable to research departments and hospitals.
