Embodiment 1
[0043] In a specific embodiment of the present invention, a closed-loop molding control system of the composite shell is adopted to integrally form and wind a compound shell with medicine of a flexible cross-section mandrel with a diameter of 300 mm and a length of 1000 mm. This embodiment solves the problem of insufficient rigidity of the mandrel when the viscoelastic grain acts as the mandrel for winding, and the problem of easy deformation during the belt tension winding process that causes the size change of the winding layer, as well as the problem of the integrated molding of the engine outer shell structure. The problem of variable cross-section improves the fine control of product quality.
