The single-wall corrugated pipe production line supports forward and backward movement as well as center height adjustment functions. It can flexibly adjust the position of the molds according to different pipe diameters (such as DN200-DN1200) and corrugation depths to ensure uniform wall thickness of the pipes. The vacuum automatic feeding system uses negative pressure to convey raw materials, preventing dust from spilling out. At the same time, it is combined with the automatic feeding device to achieve stable supply of raw materials, reducing the frequency of machine shutdown for replenishment.
