The working principle and the advantages of the invention are as follows: when the tissue embedding machine is used, the working process is as follows:

as shown in fig. 1, 2 and 4, the motor 10 is started to operate, the motor 10 drives the crankshaft 29 to rotate, so that the crankshaft 29 drives the tubular shaft 51 to rotate, after the heating assembly in the preheating chamber 16 heats paraffin therein to be melted and reaches a corresponding temperature, the first thermostat valve 18 is opened, so that the molten paraffin in the preheating chamber 16 flows into the filtering cylinder 4, the rotation of the tubular shaft 51 synchronously drives the spiral blade 52 to rotate, so that the spiral blade 52 conveys non-melted paraffin particles and particle impurities upwards and discharges the paraffin from the slag discharge cylinder 45, the paraffin continues to be heated and heated after entering the filtering cylinder 4, on one hand, the melting efficiency of paraffin is improved, on the other hand, paraffin is ensured to be in a smooth flowing state, and completely molten paraffin liquid enters the tubular shaft 51 through the pores on the tubular shaft 51, and when the paraffin temperature reaches a set temperature, the second thermostat valve 20 is opened, the paraffin liquid in the tubular shaft 51 enters the thermostatic chamber 37 through the first thermostat pipe 5, the heating assembly in the thermostatic chamber 37 further heats paraffin liquid and keeps the paraffin in a constant temperature state, and on the other hand, the paraffin liquid enters the thermostatic chamber 37, so that a new paraffin liquid is prevented from entering the paraffin feeding tube 35 and directly heated by the thermostatic liquid, and the paraffin feeding tube 35, so that the paraffin is prevented from entering the paraffin tissue heated by the paraffin liquid.

As described above, the rotation of the crankshaft 29 drives the connecting rod four 48 to approach or be away from the crankshaft 29 through the connecting rod two 32, so that the connecting rod four 48 applies a pushing force or a pulling force to the swing rod 31 through the connecting rod three 33, the swing rod 31 rotates around the crankshaft 29 after being stressed, and further the swing rod 31 drives the stirring rod 17 to reciprocate in the strip-shaped through hole 19 through the connecting rod one 23, attention needs to be paid, the swing rod 31, the connecting rod one 23 and the connecting rod three 33 cannot be in the same linear position all the time, thereby avoiding a self-locking phenomenon, the stirring rod 17 drives the rack 49 to reciprocate through the sealing plate 24, and the rack 49 drives the crushing shaft 15 to rotate through the gear five 50, when the paraffin blocks are thrown into the crushing barrel 14 through the material supplementing port 7, the crushing shaft 15 crushes the paraffin blocks, thereby accelerating the heating area of paraffin, and further improving the paraffin melting efficiency.

As mentioned above, the rotation of the crankshaft 29 synchronizes the rotation of the gear three 30, so that the gear three 30 drives the gear one 25 to rotate through the gear two 28, and further the gear one 25 drives the stirring rod 17 to rotate synchronously, so that the stirring rod 17 stirs and mixes the paraffin in the preheating cavity 16, and the stirring rod 17 also moves in a reciprocating manner in the strip-shaped through hole 19, thereby further accelerating the melting efficiency and effect of the paraffin.
