The application discloses a bottle cap and bottle body continuous screwing equipment and operation method of barrier bottles, and relates to the technical field of screwing equipment. The bottle cap and bottle body continuous screwing equipment and operation method of barrier bottles are characterized by the following: a U-shaped frame is arranged in the outer middle part of the conveying mechanism. The worn spliced screwing plate can be replaced in a targeted manner through the cooperation of the T-shaped block, the sealing plate and the bolt, and the whole screwing assembly does not need to be replaced, so that the use cost is reduced. Through the cooperation of the bearing sliding block, the third spring, the U-shaped cross link and the brush, the two high-friction long plate assemblies are far away from each other to release the clamping of the bottle cap as the bevel gear moves downward.
