The semi-automatic double-head paste filling machine features outstanding efficiency: the two filling heads operate synchronously, increasing efficiency by nearly double compared to single-head equipment. Equipped with a servo system for precise speed control, the filling speed can reach 30-60 bottles per minute under normal working conditions, and the speed can be flexibly adjusted according to the material viscosity. It is compatible with various container specifications, allowing for quick model changeover and reducing downtime. The flexible switching between manual and automatic modes ensures the continuity of small and medium batch production, effectively reducing efficiency loss caused by manual intervention and significantly increasing output per unit time.
