A sealing device of a cement paste spraying mechanism comprises a compartment body, a driving roller shaft, a driven roller shaft, an end face mounting flange, a packing mounting ring, an aramid fiber packing ring, a sealing rubber strip, an end face flange, an opening flange, a copper sleeve, a bouncing device, a sliding block, a copper sleeve positioning block, a gear and a chain wheel. When the distribution system runs, one end face of the aramid fiber packing ring is in friction sealing with the end face flange, cement paste is prevented from flowing out from a shaft hole of the end face flange, and the sealing rubber strip is mounted between the end face flange and the end face mounting flange, so that the cement paste is prevented from flowing out from a mounting gap. The fastening bolts on the two sides of the end face flange are regularly re-tightened, so that the sealing performance of the aramid fiber packing ring and the sealing rubber strip can be continuously kept, and the normal operation of the
