The utility model discloses a twine FRP pipe production line steel band mould shaft in succession to propulsion system, including main shaft, support disc, aluminum beam and steel band, be provided with the cam disc on the main shaft, the cam disc is close to aluminum beam's side is the helicoid that spiral shell screwing in rose, and every aluminum beam or aluminum beam at the interval are being close to cam disc one side is provided with the promotion the axial propeller that the steel band gos forward. The utility model discloses the mould that will twine the steel band constitution outside aluminum beam is along with the rotatory a week of main shaft impels 1 width of the steel strip to can realize reliable and stable propulsion, the solid of revolution mould of constituteing the surface by the steel band has promptly realized that even fine pitch impels. This propulsion output has reliable and stable characteristics, can guarantee the requirement of the reliable and stable pitch of propulsion of 360 degree rotatory a weeks, avoids appearing the variable -pitch phenomenon of non - expectancy, ensures the materials quality of pipe wall.
