The invention relates to the technical field of bottle blowing machines, in particular to a conveying mechanism of a full-automatic double-channel bottle blowing machine. The conveying mechanism comprises a feeding device, a first blowing device and a second blowing device; the feeding device comprises a material box, a first conveying belt, a sliding way, a second conveying belt and a third conveying belt; the first blowing device and the second blowing device comprise conveying components, blowing components, cooling components, discharging components and reset components; and a lifting board is arranged at the tail end of the third conveying belt, the two sides of the lifting plate are provided with a first lifting block and a second lifting block respectively, and a heating component is arranged at the tail end of the lifting plate. According to the conveying mechanism, the first conveyor belt, the second conveyor belt and the third conveyor belt are coordinated to work so that bottle blanks can be loaded and positioned on the conveying components, the bottle blanks are conveyed by the conveying components and sequentially pass through all the working components, and automaticconveying of the bottle blanks in the blowing process is completed; and a special-shaped plate is adopted to replace an air clamp and an air cylinder, so that demands on energy sources is reduced, andcost of the bottle blowing machine is reduced.
